High-voltage junction box of hybrid electric vehicle rear axle electric drive system

The utility model discloses a high-voltage junction box of a rear axle electric drive system of a hybrid electric vehicle. The high-voltage junction box comprises a high-voltage junction box shell, the motor controller is connected with the power battery through the power battery output positive electrode end and the power battery output negative electrode end; the motor controller is connected with the motor through a three-phase circuit; a wiring end of a charging input circuit is arranged on the high-voltage junction box shell between the power battery output positive electrode end and thepower battery output negative electrode end; and the charging input line is connected with a charging relay in the high-voltage junction box shell. By the adoption of the technical scheme, only the positive cable and the negative cable of the power battery enter the high-voltage box junction box, the output UVW three phases are directly connected to the motor, the power utilization requirements ofother loads can be reason
