CTS 6.6kW IP67 Waterproof On board charder OBC with CAN Bus Communication for electric vehicles

Based in Hunan China, CTS specializes in high-performance on-board charging solutions for electric vehicles. Our CTS 6.6kW IP67 Waterproof On-Board Charger (OBC) with CAN Bus Communication is engineered for passenger EVs, light commercial vehicles, and EV conversion projects. Designed in compliance with national standards for charging equipment, this charger delivers high efficiency, compact size, excellent stability, and long service life. Featuring IP67-rated waterproof housing, wide operating temperature range (-40°C to +85°C), and intelligent CAN bus communication for seamless integration with BMS and vehicle VCU, we offer one-stop OEM & ODM solutions with full automotive-grade reliability.

• Smart CAN Bus Communication & Advanced Diagnostics Built-in CAN bus (J1939 / custom protocol) enables real-time voltage, current, and temperature monitoring, automatic start/stop based on BMS commands, CC/CV multi-stage charging profile, and fault diagnosis. Supports UDS diagnostics and CAN wake-up function for advanced vehicle communication and remote troubleshooting.
• IP67 Waterproof & Rugged Durability Fully sealed IP67-rated aluminum housing ensures safe operation even under short-term water immersion conditions. Withstands vibration, temperature changes, dust, and moisture in engine bays or underbody installations, delivering reliable performance in harsh environments.
• Wide Temperature Range & Intelligent Thermal Protection Operates reliably from -40°C to +85°C with built-in temperature sensor that automatically shuts down output at internal 90°C for safety. Dual cooling options—air cooling and liquid cooling—ensure efficient heat dissipation and stable performance under all operating conditions.
• Comprehensive Multi-Layer Protection Integrated protections against overvoltage, undervoltage, overcurrent, short-circuit, overtemperature, and reverse electrical connection. Thermal shutdown with automatic recovery ensures safe operation under hazardous conditions, providing peace of mind for both drivers and fleet operators.
• High Efficiency Up to 96% Delivers exceptional charging conversion efficiency up to 96% to minimize energy loss and reduce charging costs. Optimized efficiency across the full output power range ensures maximum energy utilization and lower operating expenses.
• Optional 12V DC/DC Converter Available integrated 12V DC/DC converter provides power for low-voltage electric vehicle equipment (lights, wipers, infotainment, etc.), simplifying vehicle electrical system integration and reducing overall system cost.
• Programmable CC/CV Charging Profiles Supports programmable constant current / constant voltage charging profiles with high precision—±1% constant pressure accuracy and ±2% constant current accuracy—adapting to different battery chemistries and charging requirements.
• Compact & Lightweight Design Compact dimensions and lightweight construction enable easy installation in tight vehicle spaces. Optimized modular design accelerates vehicle R&D and conversion projects while reducing installation complexity.
• Full OEM & ODM Customization Fully customizable output voltage (50V–440V), connectors, communication protocols (CAN/RS485), and cooling methods. Compatible with various electric vehicles and charging station equipment, meeting diverse customer requirements worldwide.
• Complete Lab Testing & Quality Assurance CTS delivers customized power solutions for OEMs, system integrators, and mobility partners worldwide. Every charger undergoes rigorous testing including electrical performance and functional tests, safety and insulation tests, environmental and reliability tests, air leakage test, and charging compatibility test. Total annual capacity: 300,000 units with 3 assembly, testing, and packaging (ATP) lines. All products are 100% aging-inspected before shipment, ensuring long-term stability and reliability in real-world applications.
