The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). The OBC is the interface between the car and the public grid. It converts the energy from the network grid AC (Alternative Current). A High Voltage Power Distribution Unit is an electrical assembly designed to route, protect, and monitor high-voltage circuits. It acts as the central hub for distributing power from the main battery or energy storage system to inverters, DC-DC converters, compressors, heaters, pumps, and auxiliary. High voltage distribution box is the control part of EV power supply, which has the functions of power distribution, current measurement, short circuit protection, charge and discharge control, pre-charging, manual emergency stop and insulation testing port. Features: 1) quick dial connector and. As a key electrical equipment for receiving and distributing high-voltage electric energy in the power system, the high-voltage distribution cabinet plays an indispensable role in the safe and stable operation of the power system. There are many types of components in the cabinet, and each has a. To support these demands, HUBER+SUHNER delivers innovative modular distribution boxes engineered to adapt to the changing requirements of modern vehicle architectures.
