CDU8KM64 is a liquid-cooled, specifically designed for pure electric vehicles, can 

freely combine OBC+DC/DC+CDU, and high-voltage distribution unit ‘3-in-1’, conversion switching

power converter. OBC charger adopts advanced resonance technology, high efficiency, high power, 

small size, reliable work, charging mode using constant power and constant voltage automatic state 

transition, effectively saving the charging time. Wide input and output voltage range with active power 

factor correction, zero pollution to the grid. Using CAN2.0B communication protocol, with intelligent 

charging function, intelligent monitoring fault alarmprotection function, Built-in battery management 

system wake-up signal to power for BMS. DC-DC high voltage input and low voltage output adopts 

advanced fully digital technology, high power density, small size, reliable working method, with constant 

current and constant pressure automatic state conversion. Using CAN2.0B communication protocol, with 

intelligent charging function, with intelligent monitoring fault alarm and protection function.This power 

supply is specially designed for high voltage battery charging and buck conversion of electric vehicles. 

Reducing the number of vehicle wiring harness connector and the trouble caused by split power supply 

installation.The power supply adoptsliquid-cooled design, synchronizing with world-class automotive 

power supply manufacturers, the performance of the unit have reached and exceeded the international 

counterparts horizontal. Longer trouble-free operation time and reducing the natural defect risk caused 

by air cooling method.
