The invention discloses a storage battery charging system and method and an automobile. The system comprises a photovoltaic module, a photovoltaic controller and a voltage converter. The photovoltaic module is respectively connected with the photovoltaic controller and the voltage converter, the photovoltaic controller is connected with the storage battery, and the voltage converter is connected with the storage battery; according to the method, the photovoltaic module is connected with the voltage converter, when the current residual electric quantity is lower than the preset electric quantity threshold value, the open-circuit voltage is lower than the preset voltage threshold value and the vehicle state is the power-off state, the photovoltaic module is controlled to output energy to the voltage converter, and the voltage converter is awakened; and then the awakened voltage converter outputs the charging voltage corresponding to the storage battery to charge the storage battery, so that power is supplied to the storage battery under the condition that the power generation capacity of the photovoltaic module is weak and the storage battery cannot be charged, and the situation that the vehicle cannot be started due to the feed of the storage battery is avoided.

    本发明公开了一种蓄电池充电系统、方法及汽车,该系统包括:光伏组件、光伏控制器以及电压变换器;光伏组件分别与光伏控制器以及电压变换器连接,光伏控制器与蓄电池连接,电压变换器与蓄电池连接;在本发明中通过将光伏组件与电压变换器建立连接,在当前剩余电量低于预设电量阈值、开路电压低于预设电压阈值且车辆状态为下电状态时,控制所述光伏组件将能量输出至电压变换器,对电压变换器进行唤醒,然后利用唤醒后的电压变换器输出所述蓄电池对应的充电电压,为所述蓄电池进行充电,从而实现了光伏组件发电能力弱无法为蓄电池进行充电的情况下为蓄电池进行供电,避免车辆因蓄电池馈电而无法启动。
