The invention relates to a high-voltage distribution board circuit. The high-voltage distribution board circuit comprises a charging circuit body, a main power circuit body, an auxiliary power circuit body and a monitoring circuit body. The monitoring circuit body is connected with the charging circuit body, the main power circuit body and the auxiliary power circuit body through a sensor. The monitoring circuit body comprises an MCU, an NTC signal amplifier circuit, an isolation type voltage transducer, a current signal amplification circuit, a fuse monitoring circuit with an isolator, a high-voltage interlocking monitoring circuit, an intermediate relay circuit and a CAN communication circuit. By detecting multi-point voltage, current, temperature, the state of the connector and the state of a fuse of the circuit bodies in real time and analyzing and controlling the multi-point voltage, the current, the temperature, the state of the connector and the state of the fuse of the circuit bodies through a master control chip of a master control circuit board, safe and reliable operation of the high-voltage circuit bodies is achieved. Compared with an existing high-voltage distribution box, besides the fact that requirements for all functions of an existing circuit are met, capacitance safety investment operation is simplified, and the bus pre-charging function, the main contact safety investment function and the main contact fault monitoring function of the charging circuit body are added.
