The invention provides a high-voltage accessory system of a P2 architecture vehicle and a control method, and relates to the technical field of P2 architecture hybrid vehicles, the high-voltage accessory system comprises an engine, a high-voltage power battery, a generator, a DCDC module, a high-voltage steering oil pump, a 24v low-voltage storage battery and a whole vehicle controller; the engine is connected with the generator through the belt pulley; the high-pressure power battery is connected with the DCDC module, the high-pressure air pump and the high-pressure steering oil pump. When the vehicle control unit detects that the electric quantity of the 24v low-voltage storage battery is lower than a preset value, the vehicle control unit controls the engine to drive the generator to charge the 24v low-voltage storage battery. And on the premise that the electric quantity balance of the low-voltage storage battery and the power utilization of the vehicle-mounted low-voltage accessory are maintained, the power utilization efficiency of the whole vehicle can be remarkably improved. And through reasonable control of the vehicle control unit, energy consumption can be reduced as much as possible under the condition that normal work is met.

    本发明提供一种P2架构车辆的高压附件系统及控制方法,涉及P2架构混动车辆技术领域,包括:发动机、高压动力电池、发电机、DCDC模块、高压转向油泵、24v低压电瓶以及整车控制器;发动机通过皮带轮与发电机相连;高压动力电池分别和DCDC模块、高压气泵以及高压转向油泵相连;整车控制器检测到24v低压电瓶电量低于预设值时,整车控制器控制发动机驱动发电机给24v低压电瓶充电。在维持低压蓄电池电量平衡及车载低压附件的用电前提下,还能够显著提高整车的用电效率。还通过整车控制器合理控制,可以在满足正常工作的情况下,尽可能减低能耗。
