The invention relates to a vehicle-mounted high-voltage power distribution control method, device and equipment and a vehicle, which are used for solving the problem that when an alternating current discharge control circuit DCAC and a direct current conversion control circuit DCDC work at the same time, the rated output power of the direct current conversion control circuit DCDC is reduced, so that the low-voltage load power supply of the whole vehicle cannot be met. The vehicle-mounted high-voltage power distribution control method comprises the following steps: when an alternating-current discharge control circuit DCAC and a direct-current conversion control circuit DCDC work at the same time, according to the fault state of the alternating-current discharge control circuit DCAC, the working state of the direct-current conversion control circuit DCDC, the voltage of a low-voltage storage battery and the electric balance state of the low-voltage storage battery, controlling the direct-current discharge control circuit DCAC and the direct-current conversion control circuit DCDC; the AC discharge control circuit DCAC is temporarily shut down or the output power of the AC discharge control circuit DCAC is temporarily limited.

    本发明涉及一种车载高压配电控制方法、装置、设备及车辆,用于解决交流放电控制电路DCAC和直流转换控制电路DCDC同时工作时,因直流转换控制电路DCDC的额定输出功率下降导致整车的低压负载供电无法满足的问题。该车载高压配电控制方法包括:在交流放电控制电路DCAC和直流转换控制电路DCDC同时工作时,根据交流放电控制电路DCAC的故障状态、直流转换控制电路DCDC的工作状态、低压蓄电池的电压和低压蓄电池的电平衡状态,临时关停交流放电控制电路DCAC或者临时限制交流放电控制电路DCAC的输出功率。
