The invention discloses a hybrid power system control method and system. The control method comprises the steps that in a driving preparation completion mode, a vehicle control unit determines a power demand, if the power demand exceeds the power capacity of a power battery, a fuel battery is started, and if the power demand does not exceed the power capacity of the power battery, the vehicle control unit works in a pure electric mode; in the parking charging mode, the whole vehicle control unit is awakened when the solar cell can be used, the whole vehicle control unit sends charging available information to the terminal, and when the charging condition is met, the whole vehicle control unit controls the relay to be powered on and controls the solar cell to charge the power cell. According to the embodiment of the invention, the solar cell and the fuel cell cooperatively work to provide power for the vehicle, and when the vehicle is in the parking charging state, the solar cell control unit controls the solar cell to charge the power cell according to the power of the solar cell and the charge state of the power cell; solar energy and battery electric energy are fully utilized, and the power supply efficiency is improved.

    本发明公开了一种混合动力系统控制方法及系统。该控制方法包括:在行车准备完成模式下,整车控制单元确定功率需求,若功率需求超过动力电池的功率能力,启动燃料电池,若没有超过,则工作在纯电动模式;在停车充电模式下,太阳能电池可使用时唤醒整车控制单元,整车控制单元向终端发送充电可用的信息,在满足充电条件时,整车控制单元控制继电器上电,并且控制太阳能电池为动力电池充电。本发明实施例通过太阳能电池与燃料电池协同工作为车辆提供动力,且当车辆处于停车充电状态时,太阳能电池控制单元根据太阳能电池的功率和动力电池的荷电状态控制太阳能电池为动力电池充电,实现了充分利用太阳能和电池电能,并且提高了供电效率。
