The invention discloses an integrated control system and control method for an intelligent new energy commercial vehicle, and relates to the technical field of integrated control. The integrated control system comprises a high-voltage charging and distribution circuit, a DC/DC module, a motor control circuit and a main control board; the input end of the high-voltage charging and distributing circuit is connected with the power battery; the motor control circuit is provided with a pre-charging circuit, a discharging resistor, a motor control module and a current sensor; the main control board is provided with a plurality of driving circuits, a plurality of detection circuits, a plurality of voltage sampling circuits and a plurality of current sensor power supply and sampling circuits; the main control board is used for receiving information of the vehicle control unit and the battery management system, controlling the contactor to be closed or opened and feeding back the state of the contactor. The system can further integrate a circuit, can be compatible with a multi-branch power battery, and reduces the risk that a vehicle breaks down due to the fault of a battery branch.
