CTS 345V 400V 80kWh Electric Vehicle Battery LiFePO4 System with Liquid Cooling for Electric Bus OEM Solution
In the transition to public transit electrification, thermal management and cycle life are the pillars of operational efficiency. The CTS 345V/400V 80kWh LiFePO4 Battery System is engineered specifically for electric buses and features advanced liquid cooling technology. Whether in extreme summer heat or freezing winters, our system maintains cells at their optimal temperature range, ensuring superior safety, extended range, and a service life exceeding 10 years for high-intensity transit operations.
- Advanced Liquid Cooling Management: Unlike traditional air cooling, liquid cooling provides more uniform and efficient temperature regulation. It effectively prevents thermal runaway and maintains stability during fast charging or steep climbing, extending cell life by over 20%.
- High-Voltage System Efficiency: The 345V-400V platform optimizes motor efficiency, reduces vehicle wiring weight and energy loss, significantly increasing the overall driving range.
- Grade A LiFePO4 Automotive Cells: We utilize only brand-new Grade A LiFePO4 cells. The inherent thermal stability of LFP offers the highest level of safety for public transport, with a cycle life of 3,500-4,000+.
- Full OEM/ODM Customization: As an original manufacturer, we offer deep customization from mechanical structures (box dimensions) and electrical design to communication protocols (CAN 2.0/SAE J1939), perfectly fitting various bus chassis.
- Intelligent Multi-Tier BMS: The integrated smart BMS monitors individual voltage, temperature, and system insulation resistance in real-time, supporting remote diagnostics and OTA updates.
