Product Introduction
PRODUCT PROFILE
Bus bar is an important part in the electrical system, because of the rapid development of new energy vehicles, automotive electrical bus bar has been widely used.High-voltage Power Distribution Unit (PDU) is responsible for Power Distribution and management in high-voltage system solutions of new energy vehicles.Through electrical bus bar and wire harness, the high-voltage components are electrically connected to provide charging and discharging control, high-voltage components power-on control, circuit overload and short-circuit protection, high-voltage sampling, low-voltage control and other functions for the vehicle to protect and monitor the operation of the high-voltage system.Structurally, PDU is mainly composed of copper bars, relays, fuses, pre-charged resistors, and current collectors.
