2-IN-1 CCU(144V)

半岛 two-in-one vehicle charging system low-voltage platform, integrated the traditional 6.6KW bi-directional OBC, 1.5KW DC\DC with high power density at system level.

Using magnetic integration technology solution to innovatively integrate the product's primary side winding, high voltage winding and low voltage Busbar at the system level.

The OBC function converts AC power for high-voltage battery charging and low-voltage system power supply during charging, with freely distributable output power.

DCDC function converts power battery high-voltage power to low-voltage power for powering the entire vehicle's low-voltage system.

Advanced 3D waterway heat dissipation design makes the product volume effectively controlled and easy for flexible installation in the whole vehicle.


• Patented magnetic integration design, ultra-high power density integration of 2 major functions: OBC, DCDC.

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

• OBC mode with a maximum 14V low-voltage power output capability of 800W.

• integrated traditional full-bridge 1.5kW DCDC, and can withstand 1.8kW peak power for 6min.

• Low-voltage signal terminals with multiple interfaces reserved for flexible configuration of signals required by the whole vehicle system.

• Full DSP digital control, flexible customized maintenance, all software can be upgraded online.

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