Power Control Unit

The PCU module, as a key component of the DC charging controller, mainly implements functions such as high-voltage DC contactor control, charging module communication, and cooling system control. Its main functions are as follows: 1) Communication with the CCU charging control board, with remote debugging capability. 2) Communication with the charging modules. 3) Communication with the OCU. 4) High-voltage DC contactor control and feedback sampling. 5) Cooling fan system control. 6) Detection of surge protective devices, AC contactors, and access control switches. 7) Power allocation control of the charging modules.
