The high-voltage electrical box is a power distribution box
What is a high voltage box? 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). The distribution box is a very important component of the power system. It is responsible for transmitting electrical energy from the power station to various electrical equipment. In this article, we will explain in detail how it works. A high voltage junction box (HVJB) in an electric powertrain is a critical electrical component that manages and distributes high voltage electrical power from the main battery pack to various high-voltage subsystems within an electric vehicle (EV) or hybrid vehicle. Our portfolio of HV PDUs enables controlled power flow.
