The high-voltage distribution box in an electric vehicle acts as a central hub that distributes energy from the high-voltage battery to critical components such as the motor controller, accessory motor controllers, and DC/DC converters ( ). It integrates multiple functions, including:
The Vehicle Control Unit (VCU) oversees the operation of the high-voltage distribution box. It monitors voltage, current, and system status, coordinating the engagement of high-voltage contactors to safely connect or disconnect the battery from the load ( ). Key principles include:
The VCU high-voltage distribution box combines power routing, safety, and intelligent control. It ensures that high-voltage energy is delivered efficiently to motors and auxiliary systems while protecting the vehicle from overcurrent, inrush, and leakage hazards. By integrating contactors, pre-charge circuits, and monitoring systems, the VCU maintains safe and reliable operation of the electric drivetrain ( ).
