Product Description


6.6kW BC Series Liquid-Cooled EV Battery Charger (112-225VDC)

The DBC-Series 6.6kW EV Battery Charger’s rugged cast construction with a fully isolated output. This versatile under-the-hood charger is designed for harsh automotive environments providing years of reliable service. The DBC Series is designed for today and to keep your products ready to meet the requirements of the future.

The DBC-Series chargers have the integrated SAE J1772 (type 1), Mennekes (type 2), GB/T 20234.2, and CHAdeMO interface options and is IP67 rated (submersible). Communication is achieved through 2 CAN Bus interfaces. The DBC-Series Chargers are capable of charging up to a 900V Battery Pack without the need for a center tap and under full BMS control. You can parallel pairs in series to charge up to 900V battery packs at 13.2kW, 19.8kW and 26.4kW. The charger is designed to meet the stringent shake and vibration requirements of GMW3172. With this ruggedness, the charger can be mounted virtually anywhere onboard or off-board without the risk of damage from water or dust.

Up to the first 10 chargers are shipped with all of the external cables, VIP Control Software and User Manual at no extra charge. Chargers are shipped with everything needed to integrate it into your vehicle. After the first 10 chargers, Current Ways will provide you with our approved suppliers for the cables so you can integrate them into your wire harnesses, or you can purchase the cable kits from Current Ways. Current Ways cables must be used to preserve the IP67 rating and warranty. Our excellent customer support is available most anytime to assist you with setting up and integrating the charger into your system.

The BC-Series is designed to be adaptable to the requirements of the future.
