Differences Between Pure Electric Vehicle, Range Extended Electric Vehicle and Fuel Cell Vehicles
Differences Between Pure Electric Vehicle, Range Extended Electric Vehicle and Fuel Cell Vehicles
1. Pure Electric Vehicle (PEV) This is what we often refer to as a pure electric vehicle,  only a lithium battery (no combustion engine) provides power with the help of an electric motor to drive the car forward.   Advantages: (1) Very little energy is lost from charging into the battery, to the battery driving the motor, driving the vehicle at low cost and emissions; (2) The sources of electricity are varied. It is less polluting and less costly than thermal power; (3) There are peaks and valleys in social electricity consumption. Many of the country's unit capacities are wasted during idle power hours, while charging vehicles at this time can cut the valley and fill the peak, optimising the demand for electricity on the grid and saving social costs;   2. Extended-Range Electric Vehicles (EREV) Generate electricity through fuel, charge the battery and the electric motor drives the car. The electric motor drives the car and has the good characteristics of an electric car. It can be equipped with smaller capacity batteries, low weight and low cost. Because it can generate electricity through fuel, there is no mileage anxiety. The disadvantage is that it cannot provide power at the same time as HEV fuel and electricity, and the power is not as good as HEV.   Advantages: The advantages of supercharged electric vehicles are similar to pure electric, the difference is that the engine can be used to power the battery. It has the advantages of quietness and high starting torque of electric vehicles, and can be used as a pure electric vehicle, with lower cost of use by only charging and not refuelling under convenient charging conditions.     3. Fuel cell vehicles (FCV) Fuel cell vehicles (FCVs) provide the energy needed for driving by converting the chemical energy of fuel into electric energy, and the vehicle is driven by an electric motor. Currently, the main type of fuel is hydrogen. The energy of fuel cell is replenished by adding fuel, so the time is similar to refuelling. In addition, the fuel cell energy conversion process is highly efficient, noiseless, and has no pollutant emissions. The biggest difficulties at present are the difficulty in obtaining fuel, the difficulty in storing and transporting fuel, and the scarcity of hydrogen refuelling stations.   Advantages: (1) There is no problem of range and energy refilling. No range anxiety. (2) No problems of high-capacity battery life and cost of pure electric vehicles, and high pollution from high-capacity battery end-of-life like pure electric vehicles.

Differences Between Hybrid Electric Vehicle and Plug-in Hybrid Electric Vehicle
Differences Between Hybrid Electric Vehicle and Plug-in Hybrid Electric Vehicle
Hybrid Electric Vehicle (HEV)   Hybrid Electric Vehicle (HEV) here refers to a traditional hybrid vehicle, which is powered by a fuel engine and an electric motor in parallel. Generally the battery capacity is small and cannot be charged externally, and the energy of the battery is obtained through energy recovery.   Advantages: (1) No mileage anxiety compared to pure electric vehicles because of the reliance on fuel to provide energy; (2) Low fuel consumption compared to traditional internal combustion engine vehicles and longer range than regular fuel vehicles with the same tank size. Low-speed and congested roads in urban areas are dominated by electric motors, which are smooth, quiet, and significantly reduce emissions, making them relatively cleaner.   Plug-in Hybrid Electric Vehicle (PHEV)   Unlike HEVs, PHEVs have an on-board power battery that can be recharged by an external power source. Power is provided by the fuel engine and electric motor. This model can switch between pure electric, pure fuel and hybrid fuel-electric modes in real time, etc. For details, refer to Super Hybrid Technology DMi, DHT, and so on.   Advantages: (1) Plug-in hybrid cars are the perfect transition from pure petrol to pure electric cars, refer to BYD A-class sedan laurel BYD Qinplus dmi, fuel saving and electricity saving, fill up a tank of fuel ran 1250 km, if daily work, can be completely used as a tram. (2) Handling and comfort, the motor-driven model, with no gearbox, is smooth and powerful.

How to deal with the inconsistency of lithium batteries
How to deal with the inconsistency of lithium batteries
The inconsistency in battery cell performance is formed during the production process and deepened during use. The cells within the same battery pack remain weak and accelerate to weaken. The degree of dispersion of parameters between individual cells increases with the deepening of aging.   Currently, engineers mainly consider three aspects when dealing with inconsistencies in individual battery cells. Single battery sorting, thermal management after grouping, and balancing function provided by the battery management system in case of a small amount of inconsistency.   1) Sorting   Different batches of battery cells should not be used together in theory. Even cells from the same batch need to be screened and the cells with relatively concentrated parameters should be placed in one battery pack and the same battery pack.   The purpose of sorting is to select cells with similar parameters. Sorting methods have been studied for many years, mainly divided into two categories: static sorting and dynamic sorting.   Static sorting involves selecting characteristic parameters such as open circuit voltage, internal resistance, and capacity of the cells, selecting target parameters, introducing statistical algorithms, setting screening criteria, and finally dividing the cells of the same batch into several groups.   Dynamic screening refers to the screening of the characteristics exhibited by the battery cells during the charging and discharging process. Some choose the constant current and constant voltage charging process, some choose the pulse impact charging and discharging process, and some compare the relationship between their own charging and discharging curves.   Combining dynamic and static sorting, static screening is used for preliminary grouping, and dynamic screening is carried out on this basis. This results in more groups being divided and higher screening accuracy, but the cost will also increase accordingly.   This reflects the importance of the scale of lithium battery production. Large scale shipment allows manufacturers to conduct more refined sorting and obtain battery packs with closer performance. If the production is too small and there are too many groups, a batch cannot be equipped with a battery pack, and even the best method cannot be applied.   2) Thermal management   In response to the issue of inconsistent internal resistance and heat generation in battery cells. The addition of a thermal management system can adjust the temperature difference of the entire battery pack to maintain it within a small range. Cells that generate more heat still have a higher temperature rise, but they will not widen the gap with other cells, and there will be no significant difference in degradation level.   3) Equilibrium   Inconsistency in the individual cells results in some cell terminal voltages always exceeding those of other cells and reaching the control threshold first, resulting in a decrease in the overall system capacity. To address this issue, the battery management system BMS has designed a balancing function.   A certain battery cell reaches the charging cut-off voltage first, while the voltage of the other battery cells lags significantly. The BMS starts the charging equalization function, or connects a resistor to release some of the electricity from the high voltage battery cell, or transfers the energy to the low voltage battery cell. In this way, the charging cut-off condition is lifted, the charging process resumes, and the battery pack is charged with more electricity.   Until now, the inconsistency of battery cells remains an important area of research within the industry. No matter how high the energy density of the battery cell is, encountering inconsistencies to disrupt the situation will greatly reduce the capacity of the battery pack.

Hazards of Inconsistency in Lithium Batteries
Hazards of Inconsistency in Lithium Batteries
The consistency of lithium batteries mainly refers to the consistency of capacity, internal resistance, and open circuit voltage. Inconsistent battery cell strings used together can cause the following problems:   1) Capacity loss refers to the formation of a battery pack consisting of individual cells, which conforms to the "barrel principle" in terms of capacity. The capacity of the worst cell determines the capacity of the entire battery pack.   To prevent overcharging and discharging of the battery, the logic of the battery management system is set as follows: during discharge, when the lowest individual voltage reaches the discharge cut-off voltage, the entire battery pack stops discharging; When charging, stop charging when the highest unit voltage touches the charging cutoff voltage.   Take two batteries connected in series as an example. One battery has a capacity of 1C, while the other has a capacity of only 0.9C. In a series connection, two batteries pass through the same amount of current.   When charging, batteries with small capacity must first be fully charged, reaching the charging cut-off condition, and the system will no longer continue to charge. When discharging, batteries with small capacity will inevitably discharge all available energy first, and the system will immediately stop discharging.   In this way, cells with small capacity are always fully charged and discharged, while cells with large capacity are always using a portion of their capacity. A portion of the entire battery pack's capacity is always idle.   2) Life loss, similarly, the lifespan of a battery pack is determined by the battery cell with the shortest lifespan. It is highly possible that the battery cell with the shortest lifespan is the one with a small capacity. Small capacity battery cells are always fully charged and discharged, with excessive output, which is likely to reach the key point of their lifespan first. When the lifespan of a battery cell ends, a group of battery cells welded together will also die with it.   3) As the internal resistance increases, different internal resistances flow through the same current, and cells with high internal resistance generate relatively more heat. If the battery temperature is too high, it will accelerate the degradation rate and further increase the internal resistance. Internal resistance and temperature rise form a pair of negative feedback, accelerating the degradation of high internal resistance cells.   The above three parameters are not completely independent. Cells with deep aging have higher internal resistance and more capacity decay. The inconsistency in battery cell performance is formed during the production process and deepened during use. The cells within the same battery pack remain weak and accelerate to weaken. The degree of dispersion of parameters between individual cells increases with the deepening of aging.

How to use electric motorcycle batteries safely?
How to use electric motorcycle batteries safely?
  As we know ,the charging temperature of lithium battery is 0℃~45℃, and the discharging temperature of lithium battery is -20℃~60℃. Lithium batteries do not have a memory effect, can be used with charging, but it should be noted that lithium batteries can not be over-discharged, over-discharge will cause a very large loss of capacity. NMC lithium battery single safe working voltage range is 2.75 ~ 4.2V, LiFePO4 battery single safe working voltage range is 2.5 ~ 3.65V, lower or higher than this voltage range of lithium ions in the battery becomes very unstable, and even cause accidents. In order to ensure that the battery is in the safe range, so you need a special charger, do not mix lead-acid charger for its charging.   When the lithium battery is left unused for a long period of time, it needs to be charged and discharged once every six months to restore its original performance. Lithium batteries need to be checked before use to see if they meet the requirements of the load, in the case of not meeting the requirements of the load or high current (more than 1C) will cause damage to the battery or shorten the life of the battery. Lithium batteries avoid frequent use in high or low temperature environments. Preferably at room temperature, temperature will have a great influence on the characteristics of lithium battery.   How to use lithium battery safely? The low-priced lithium batteries on the market are mostly assembled from dismantled and substandard battery cells, the safety risk is great. These substandard cells are combined with substandard BMS, which is the main reason for the safety issues of lithium batteries.   How to use the lithium battery correctly ? 1, the use of lithium battery charger matched with the battery pack. 2, do not use the lithium battery pack in illegal modification of high-power electric vehicles. 3, do not let the lithium battery long-term exposure to high temperatures (≥ 65 ℃). 4, in the electric car just after riding due to the high temperature of the battery pack, please let it cool down naturally for about half an hour before charging it. 5, Lithium battery can be used between 20% ~ 90% SOC to greatly extend the life of the lithium battery pack. 6, lithium battery in the winter temperature is lower than 15 ℃ temperature, the electric car range has a certain amount of shrinkage is a normal phenomenon. When the temperature returns to about 25 ℃, the range of the electric car back to normal.

Comparison of Different Types of Lithium Batteries
Comparison of Different Types of Lithium Batteries
Now Lithium batteries are a new trend , there are kinds of lithium batteries, what is the difference?   The lithium batteries used more widely on the market are mainly divided into three Types: ternary lithium-ion batteries(NMC batteries), lithium manganate batteries(LiMnO batteries), Lithium iron phosphate battery(LiFePO4 batteries). Among them, ternary lithium batteries and lithium iron phosphate batteries are more popular in the market. Among the three, the safety of lithium iron phosphate and lithium manganate is higher.   Ternary lithium-ion batteries, generally lithium nickel cobalt manganese or nickel cobalt aluminate lithium-ion batteries as the cathode material. Unlike other lithium-ion batteries, the capacity of ternary lithium-ion batteries is higher than other lithium-ion batteries, and the cycling performance of ternary lithium-ion batteries is better than that of ordinary lithium cobalt oxide lithium-ion batteries. The nominal voltage of ternary lithium-ion battery is 3.7v, and the working voltage is 2.75v-4.2v. However, the thermal stability of ternary lithium is poor, so the safety is not as good as that of lithium iron phosphate and lithium manganate.   Lithium manganese acid battery, refers to the battery using lithium manganate material in the positive pole, the nominal voltage of lithium manganate battery is 2.5~4.2v, lithium manganate battery is widely used for its low cost and good safety. Li-Mn2O4 battery has the advantages of low cost, high stability and low temperature performance, but it also has the disadvantages of low energy density, poor high temperature performance and fast attenuation.   Lithium iron phosphate battery, is a lithium ion battery that uses lithium iron phosphate as the cathode material. Lithium iron phosphate power battery, the cycle life reaches more than 3000 times, standard charging (5 hours rate) use, can reach 2000 times. Theoretical life will reach 8~10 years, which is the preferred type of battery cell with both safety and cost-effectiveness.   For our CTS Battery , we are using NMC and LiFePO4 materials , NMC batteries are usually used on EV , e-bike applications ,its has higher energy density ,lighter ,smaller . and LiFePO4 materials are more widely used due to its excellent safety and cost-effectiveness. CTS battery can OEM battery pack from 12v-1000v, 10-1000ah, which can be used in electric vehicle, E-bike, UPS, energy storage system, telecommunication base station,E-scooter,golf cart,electric boat, cleaning car , electric wheelchair, etc.   If you have any inquiry , feel free to contact CTS battery , thank you .

Key process of power battery assembly
Key process of power battery assembly
As an important component of electric vehicles, power batteries have very high requirements on temperature, safety and performance. Therefore, the assembly of power batteries has also become the focus of electric vehicle assembly.。   Key process of power battery assembly:   The power battery system is a complex system, which consists of BMS battery management system, multiple battery modules and housings. Among them, the battery pack is composed of multiple modules, and each module is composed of multiple battery cells connected in series and parallel.   The assembly of the power battery pack is mainly to arrange and fasten multiple modules and check the junction box. During the assembly process, many stations are involved in safe connections, and these assembly processes are directly related to the safety of the vehicle and its occupants.   The key assembly process of the power battery pack is as follows:   1.High and low voltage connector assembly:   There are many high and low voltage connectors on the battery pack and BMS. The assembly features of these interfaces include: > Security parts need to collect data feedback, and sensor tools must be used; > When tightening, it is usually a hand-held tool and a hand-held tool. It is best to use a gun-type tool for easy grip and tightening; > The torque range is not wide, so it is best to choose a compact tool.   2.Installation of high voltage wiring harness There are total positive and total negative high-voltage wire harnesses in the battery pack that need to be connected and assembled. When the module is charged, the voltage connected to this part is as high as hundreds of volts. Usually the ground of the work station will be insulated, which is a high-voltage protection work station. In addition, insulation treatment is also required in the assembly. The insulation treatment of this part of the work station not only affects the safety of the battery, but also affects the safety of the operator.   3.Connection and installation of high-voltage busbar The high-voltage busbar is used to connect the conduction between the modules. The current is large and intensively used, and the assembly is complicated. As the key structure of the battery conduction, the safety of assembly is also very important. The negligence of assembly may cause the battery to short circuit.   4.Module Installation The battery pack is composed of multiple battery modules. The assembly of the battery modules requires moderate tightness, and each structural component has sufficient strength to prevent deformation or damage due to external forces inside the battery. The battery module is composed of multiple power cells connected in series and parallel. The assembly of the battery module needs to fix the battery module in the aluminum box. Generally, long bolts are used to go through the module and fix it to the nut at the bottom of the box. In order to save space, some battery packs adopt the form of double-layer modules, and there will be mounting module brackets to fix the upper module.     5.Cover installation In order to meet the needs of light weight and improved efficiency, battery packs usually use aluminum casings. Dozens of bolts are used to connect and assemble the upper cover and the lower box of the battery pack aluminum case. The number of bolts is large and the distribution is regular, and the tightening direction is vertically downward. During assembly, they need to be tightened sequentially to ensure that the tightening stress of the upper cover is evenly distributed.

Understanding the Lithium Battery Energy Storage System PACK
Understanding the Lithium Battery Energy Storage System PACK
With the formulation and promotion of China's strategic goal of "carbon peaking, carbon neutrality", the proportion of clean energy such as photovoltaic , wind power and power from energy storage systems will be significantly increased, which has brought huge development space for the energy storage market.   The main technical route in electrochemical energy storage is lithium-ion battery energy storage, and lithium-ion battery PACK technology is an important part of industry skills. Below, let's learn some basic knowledge of battery PACK with CTS.   1. Definition Lithium ion battery PACK is a manufacturing process for lithium-ion batteries, which means packaging, packaging, and assembly. It refers to the connection of multiple lithium ion battery celsl groups in series, taking into account system mechanical strength, thermal management, BMS matching, and other issues. Its important technologies are reflected in overall structural design, welding and processing process control, protection level, and active thermal management system. If two batteries are connected in series or parallel to form a specific shape according to customer requirements, it is called a PACK.   2. Composition of battery pack The battery pack consists of several important components, including individual battery modules, electrical systems, thermal management systems, cabinets, and BMS . ▶ Battery module: If battery PACK is compared to a human body, then the module is the "heart" responsible for storing and releasing electrical energy. ▶ BMS: Battery management system can be seen as the "brain" of batteries. Mainly responsible for measuring parameters such as voltage, current, and temperature of the battery, as well as balancing functions. Data can be transmitted to MES. ▶ Electrical system: mainly composed of connecting copper strips, high-voltage harnesses, low-voltage harnesses, and electrical assurance devices. The high-voltage harness can be seen as the "artery" of the battery PACK, transmitting the battery power to the end load continuously, and the low-voltage harness can be seen as the "neural network" of the battery PACK, transmitting the detection signal and control signal in real time. ▶ Thermal management system: There are two main methods of thermal management system: air cooling and liquid cooling, and liquid cooling can be divided into cold plate liquid cooling and immersion liquid cooling. The thermal management system is equivalent to installing an air conditioner for the battery pack. The battery generates heat during discharge mode. To ensure that the battery operates at a reasonable ambient temperature and improve its cycling life, the system temperature difference is generally required to be ≤ 5 ℃. ▶ Box: mainly composed of box, box cover, metal bracket, panel and fixing screws, it can be regarded as the "skeleton" of battery PACK, playing the role of support, resistance to mechanical shock, mechanical vibration and environmental protection.                                                                           CTS 48V 5kwh lifepo4 battery module     3. Characteristics of battery pack ▶ PACK lithium battery packs require high consistency in battery capacity, internal resistance, voltage, discharge curve, and lifespan. ▶ The cycle life of the battery pack PACK is lower than that of a single battery. ▶ Used under limited conditions (including charging, discharging current, charging method, temperature, etc.) ▶ After the lithium battery pack is formed, the battery voltage and capacity have greatly increased, and it must be protected by charging balance, temperature, voltage, and overcurrent monitoring. ▶ The battery pack must meet the voltage and capacity requirements required by the design.   4. PACK method ▶ Series parallel composition: The battery module is composed of individual cells connected in series. Parallel connection increases capacity, voltage remains unchanged, and after series connection, voltage doubles, capacity remains unchanged. For example, if 16 cells with a voltage of 3.2V are connected in series, it is 51.2V, which is called series boosting. For example, if two cells with a capacity of 50Ah are connected in parallel, there will be 100Ah, which is called parallel expansion. ▶ Battery requirements: Select the corresponding battery cells according to your own design requirements. The types and models of batteries in parallel and series should be consistent, and the differences in capacity, internal resistance, and voltage values should not exceed 2%. ▶ PACK process: The battery can be PACKed in two ways. One is laser welding, ultrasonic welding or pulse welding. This is a common welding method, which has the advantage of good reliability but is not easy to replace. The second is through contact with elastic metal sheets, which has the advantage of no welding and easy battery replacement. The disadvantage is that it may lead to poor contact. Considering the production yield, efficiency, and internal resistance of the connection point, laser welding is currently the preferred choice for many battery manufacturers.     5. How to understand the technical parameters of battery PACK   Items parameters marks Combination method 1P16S   Rated capacity 100Ah   Rated voltage 51.2V   total energy 5.12kWh   Discharge rate 1C   weight 45±0.5kg     ▶ Combination method: 1P16S Interpretation: S represents series cells, P represents parallel cells, and 1P51.2S represents 16 series and 1 parallel cells. After series connection, the voltage is doubled, and the rated voltage is 3.2 * 16=51.2V.   ▶ Rated capacity: 100Ah Interpretation: The rated capacity of a battery refers to the capacity of a battery to operate continuously for a long time under rated operating conditions. The rated capacity C of a battery, in ampere hours (Ah), is the product of the discharge current in amperes (A) and the discharge time in hours (h). So 100Ah represents discharge at a maximum current rate of 0.5C, which can last for 2 hours.   ▶ Rated energy: 5.12kWh Interpretation: Rated energy (Wh)=nominal capacity (Ah) * nominal voltage (V), so the total energy that a battery can release is related to both capacity and voltage.     If you have any questions of energy storage lithium battery , feel free to contact us , thank you

Application of Liquid Cooling system in Power Battery System
Application of Liquid Cooling system in Power Battery System
    With the requirement of IP67 for passenger cars becoming a necessity, liquid cooling systems have been widely used in power batteries.   Definition of liquid cooled plate: In a power battery system, excess heat is generated by the operation of the battery. The heat is transferred through the contact between the battery or module and the surface of the plate type aluminum device, and ultimately carried away by the cooling liquid passing through the internal flow channel of the device.  General requirements for liquid cooling plates   High heat dissipation power, able to timely export excess heat generated during the operation of the power battery, avoiding excessive temperature rise;   High reliability, working in road vehicle environments, vibration, impact, high and low temperature alternating environments, is a relatively harsh working condition for most products. However, the voltage of power batteries is often several hundred volts, and coolant leakage is a serious problem. Even if you use a coolant with good insulation performance, the insulation performance will immediately decrease when encountering external impurities. Therefore, the reliability of cooling plate sealing is very important;   The precise heat dissipation design avoids excessive temperature difference within the system, which is due to the performance requirements of lithium batteries themselves. The performance and aging of batteries are closely related to the working temperature;   The strict requirements for the weight of the cooling plate, which comes from the pursuit of energy density in the power battery system. Cooling systems that seriously lower the energy density of the system are simply unacceptable to both customers and designers.     What kind of liquid cooling plate  CTS use ?  please check below pictures , we normally put the cooling plate in the botton of the battery pack , it can adjust the battery temperature to maintain it within the temperature range suitable for battery operation; Reduce the difference between the highest and lowest temperatures inside the battery pack. except cooling system , we also can Integrated battery heating system  . if you want know more about the Battery thermal management system , feel free to contact us , thank you !

Power battery is widely used on electric vehicles for different scenario, electric boats and ships, two wheel autos like electric bicycles, scooters, and electric tools, etc. Among them, EV sector is the fastest growing one and it’s the biggest in its scale, concerning downstream applications of power batteries. Power battery is considered to be the key component to promote the development of new energy vehicle industry.   In recent years, countries in Europe, North America, East Asia and other regions are making efforts to develop clean energy by adjusting their energy mix to achieve the goal of peak carbon emissions and carbon neutrality.In the meantime, there has been continuous progress in EV related technology and infrastructure. The new energy vehicle industry is developing rapidly.   According to the statistics provided by EV Sale, the global sales volume of new energy vehicles in 2020 was 3.24 million, 43.36% more than that of last year. In 2021, the sales volume of new energy vehicles worldwide increased rapidly, reaching 6.75 million, 108% more than that of last year. This figure continues rocketing in 2022. In recent years, under the policy of vigorously promoting "carbon neutrality" and "electrification, intelligence and interconnection" of the automobile industry, major economies in the world have increased the market share of new energy vehicles. It is expected that the global new energy vehicle market will continuously and significantly develop in the next few years.   China boasts one of the largest market for new energy vehicle in the world. Propelled by policies and market force, this market has experiencing rapid development in recent years. According to the data of China Association of Automobile Manufacturers, the annual sales of new energy vehicles have rapidly increased from 18000 in 2013 to 1.206 million in 2019, with a compound annual growth rate of 101.53%, since central and local preferential policies coming into force in 2013. In 2020, the sales volume of new energy vehicles is 1.367 million. In the face of COVID-19, the sales volume of new energy vehicles grows by 10.9% than previous year. In 2021, the overall volume of production and sales of new energy vehicles is 3.545 million and 3.521 million respectively, with a record high growth of 159.5% and 157.5% than previous year.

What's the difference between lead acid battery and lithium battery?
What's the difference between lead acid battery and lithium battery?
What's the difference between lead acid battery and lithium battery?   At present, there are lead-acid batteries and lithium batteries on the market. What's the difference between lead-acid batteries and lithium batteries?   ① In terms of price, due to the better heat dissipation function and endurance function of lithium battery, the production process from packaging to sealing is also very strict; Therefore, the production cost is much higher than that of lead-acid battery.   ② The main component of positive electrode is lead dioxide, and the main component of negative electrode is lead; When the battery is charged, the main component of both positive and negative electrodes is lead sulfate.                       (Structure diagram of lead acid battery)   In the working state of lithium battery, the main component of the positive electrode is manganese dioxide, and the main component of the negative electrode is lithium metal or its synthetic metal, which uses non-aqueous electrolyte solution; In the state of charge, lithium alloy metal oxide is usually used as cathode material, graphite is used as anode material, and non-aqueous electrolyte is used as battery.                           (Structure diagram of lithium battery)   ③ The memory effect is different. After a period of time, the battery goes into sleep state, and the capacity is lower than the normal value; Lead acid battery will have memory effect, so special methods and equipment are needed to activate the battery and restore its normal capacity; Lithium battery has its own characteristics, without memory effect. It only needs 3-5 normal charge discharge cycles to activate the battery and restore its normal capacity.   ④ The service life of lead-acid batteries is generally only two years, and the number of complete charge discharge cycles is generally less than 300. The service life of lithium battery is four to five years. It is durable and can be fully charged and discharged for more than 500 times.   ⑤ Environmental protection efforts are different. Under the environmental protection policies, in order to protect the environment and reduce pollution, there is pollution caused by improper treatment in the production, use and recycling of lead-acid batteries. However, lithium batteries are relatively environmentally friendly due to their perfect packaging and sealing.

How to charge lithium iron phosphate batteries?  The correct way to use lithium iron phosphate batteries
How to charge lithium iron phosphate batteries? The correct way to use lithium iron phosphate batteries
How to charge lithium iron phosphate batteries? The correct way to use lithium iron phosphate batteries   The full name of the Lifepo4 batteries is lithium iron phosphate attery. Because its performance is particularly suitable for power application, the word "power" is added to the name, namely lithium iron phosphate power battery.   At present, the mainstream market of lithium iron phosphate batteries is used in the electric bus market and electric passenger car market, respectively. The related issues related to the charging of lithium iron phosphate have also been enlarged.   For example, can lithium iron phosphate batteries be charged every day, is the lithium iron phosphate battery charging at any time and so on.   So, let's take a look at the correct charging method of lithium iron phosphate batteries today.   Combined with the working principle of the lithium battery pack, the correct usage method mainly includes three aspects: charging, discharge, and maintenance.   1. The correct charging method of lithium battery packs   First, the principle of shallow charging and shallow discharge   Secondly, full charging can prevent overcharging. For lithium-ion batteries in the industrial industry, charging is relatively slow when using batteries in the past. It may take 8-12 hours for a single charge, while lithium battery packs can achieve fast charging. A lithium battery with the same capacity as the storage battery only takes about 4 hours to fully charge at a time, so pay attention when charging, and do not charge the lithium battery pack according to the charging time of the storage battery.   In the end, it's best not to use two things at once. In layman's terms, don't let the lithium battery work while charging. The main reason why this cannot be done is also very simple. This approach will reduce the service life of the lithium battery pack.       Improper use will lead to battery attenuation, which will affect battery life. The following points must be paid attention to:   1. Long-term parking at low temperature. The new energy vehicle batteries currently on the market are mainly divided into two types: ternary lithium batteries and lithium iron phosphate batteries. attenuation phenomenon.   2. Often charge with low battery. Since lithium-ion batteries do not have a battery memory effect, electric vehicles are like our smartphones, which can be charged as they are used, and try not to run out of power on charging.     3. Step on the accelerator heavily and brake in an emergency. Because electric vehicles have a characteristic, that is, excellent acceleration performance, some car owners like to step on the accelerator heavily, which leads to emergency braking. But it must be clear that the large current will increase the internal resistance of the battery sharply, and frequent driving in this way may even damage the battery.

All about electric car batteries
All about electric car batteries
All about electric car batteries Learn about electric car batteries, how they work and how they're recycled.   How do electric car batteries work?   Where internal combustion engined cars get energy from burning petrol or diesel, an electric vehicle gets its power directly from a big pack of batteries. These are much like a scaled up version of the lithium-ion (Li-ion) battery in your mobile phone - EVs don't use a single battery like a phone, they use instead a pack which is comprised of thousands of individual Li-ion cells working together. When the car's charging up, electricity is used to make chemical changes inside its batteries. When it's on the road, these changes are reversed to produce electricity. Electric car battery technology EV batteries undergo cycles of 'discharge' that occur when driving and 'charge' when the car's plugged in. Repeating this process over time affects the amount of charge the battery can hold. This decreases the range and time needed between each journey to charge. Most manufacturers have a five to eight-year warranty on their battery. However, the current prediction is that an electric car battery will last from 10 – 20 years before they need to be replaced. How a battery and the car's electric motor work together is surprisingly simple – the battery connects to one or more electric motors, which drive the wheels. When you press the accelerator the car instantly feeds power to the motor, which gradually consumes the energy stored in the batteries. Electric motors also work as generators, so when you take your foot off the throttle the car begins to slow down by converting its forward motion back into electricity – this happens more strongly if you hit the brakes. This regenerative braking recovers energy that would otherwise be lost, storing it in the battery again and so improving the car's range.   Electric car battery lithium-ion A Lithium-ion (Li-ion) battery is a type of rechargeable battery used in electric vehicles and a number of portable electronics. They have a higher energy density than typical lead-acid or nickel-cadmium rechargeable batteries. This means that battery manufacturers can save space, reducing the overall size of the battery pack. Lithium is also the lightest of all metals. However, lithium-ion (Li-ion) batteries contain no lithium metal, they contain ions. For those wondering what an ion is, an ion is a an atom or molecule with an electric charge caused by the loss or gain of one or more electrons. Lithium-ion batteries are also safer than many alternatives and battery manufacturers have to ensure that safety measures are in place to protect consumers in the unlikely event of a battery failure. For instance, manufacturers equip electric vehicles with charging safeguards to protect the batteries during repeated rapid charging sessions in a short period of time. Battery capacity explained Electric car battery life   Once an EV battery loses its capacity to power a vehicle, it can be used to power a home or building by contributing to a battery storage system. A battery energy storage system stores energy from batteries that can be used at a later time. If you power your home with renewable energy such as wind or solar, you can also pair it with an EV battery. You can store it up to use throughout the night when wind and sunlight are reduced. Or even during the day alongside solar or wind energy. This method of generating energy can help you save on bills and reduce the amount of energy you use from the grid. The battery on an electric car is a proven technology that will last for many years. In fact, EV manufacturers guarantee it. Nissan warrants that its electric car batteries will last eight years or 100,000 miles, for example and Tesla offers a similar guarantee.       This might seem remarkable when the battery in your mobile phone begins to wear out after only a couple of years, but during that time it might be fully charged and discharged hundreds of times. Each of these so-called charge cycles counts against the life of the battery: after perhaps 500 full cycles, a lithium-ion phone battery begins to lose a significant part of the capacity it had when new. While that might be OK in a phone, it's not good enough for a car designed to last many thousands of miles, so EV manufacturers go to great lengths to make electric car batteries last longer. In an EV, batteries are 'buffered', meaning that drivers can't use the full amount of power they store, reducing the number of cycles the battery goes through. Together with other techniques such as clever cooling systems, this means that electric car batteries should give many years of trouble-free life. In fact, in order to preserve the life of an electric vehicle battery, manufacturers ensure that there is additional spare capacity to compensate for degradation over time. So as an electric vehicle ages and the battery cycles, the additional spare capacity is used up. This allows the range of the vehicle to stay the same throughout the life of the battery. Once the battery capacity falls below 80%, drivers may start to notice a fall in the range and performance of the battery.
