2-IN-1 CCU(400V)

The product integrates the traditional 6.6KW bi-directional OBC, 2.5KW DC\DC and PDU with high power density at system level.

The system core patent-magnetic integration technology innovatively integrates the primary winding, high-voltage winding and low-voltage Busbar of the product at the system level. High-voltage winding, and low-voltage Busbar of the product at a system level. The OBC function converts alternating current for high-voltage battery charging and low-voltage system power supply during charging, allowing for flexible power allocation. The DC/DC function converts high-voltage power from the traction battery to low-voltage power for the vehicle's low-voltage system. The advanced 3D water channel heat dissipation design effectively controls the product's size and facilitates flexible installation in the vehicle.


• Patented magnetic integration design, ultra-high power density integration of 2 major functions: BOBC (OBC/DCAC), DCDC.

• Die-casting one-piece molding of the body aatented 3D waterway design to optimally meet heat dissipation.

• OBC mode allows for flexible power allocation between high and low voltage outputs to meet various vehicle application requirements.

• In DCDC mode, the 6.6kVA DCAC can start quickly within 2 seconds.

• Multiple interfaces reserved for low-voltage signal terminals, allowing flexible configuration of vehicle system signal requirements.

• Full DSP digital control enables flexible customization and maintenance, with the ability to upgrade all software online.

• Standard CAN2.0B design, customizable charging strategy according to the needs of vehicle enterprises, compatible with national standard and enterprise standard charging requirements.
