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.
