Power Distribution System Features
The main function of the high-voltage distribution box assembly is to supply the high-voltage DC power of the high-voltage battery to the high-voltage electrical appliances of the whole vehicle through the control of the contactor, and to receive the DC power of the on-board charger or off-board charger to charge the high-voltage battery. Other auxiliary detection functions, such as current detection, leakage detection, etc.
High-voltage interlocks include structural interlocks and functional interlocks. The main high-voltage connectors with structural interlocking all have an interlocking circuit. When one of the connectors is disconnected with electricity, the high-voltage battery manager will detect that there is an open circuit in the high-voltage interlocking circuit. Alarm and disconnect the main high voltage circuit electrical connection, and activate the active relief.
