The invention discloses a method and a system for automatic charging control of a photovoltaic electric vehicle battery, and an electric vehicle. The method comprises the following steps: obtaining the operation modes of the photovoltaic electric vehicle, wherein the operation modes comprise a driving mode and a parking mode; obtaining the electric quantity condition of a low-voltage battery in real time if the photovoltaic electric vehicle is in the parking mode, charging the low-voltage battery according to a charging request, obtaining the electric quantity condition of the high-voltage battery after the low-voltage battery is charged, sending a power-on request, and powering on a high-voltage battery according to the power-on request; and acquiring the electric quantity condition of the low-voltage battery in real time if the photovoltaic electric vehicle is in the driving mode, generating a charging request according to the electric quantity condition, charging the low-voltage battery according to the charging request, and supplying power to an air conditioner. The operation modes of the photovoltaic electric vehicle are obtained, power is automatically supplied to the low-voltage battery, the high-voltage battery and the air conditioner according to the operation mode to avoid battery maintenance to the maximum extent, and the battery power consumption can be automatically supplemented to prevent battery cell damage caused by over-discharge and increase the endurance mileage of the whole vehicle.
本发明公开了一种光伏电动汽车电池自动充电控制方法、系统、电动汽车,获取光伏电动汽车的运行模式,运行模式包括行车模式和停车模式;若光伏电动汽车处于停车模式时,实时获取低压电池的电量情况,根据补电请求为低压电池充电,在低压电池充电后,获取高压电池的电量情况,发送上电请求,根据上电请求为高压电池上电;若光伏电动汽车处于行车模式时,实时获取低压电池的电量情况根据电量情况生成补电请求,根据补电请求为低压电池充电,并为空调供电,本发明通过获取光伏电动汽车的运行模式,根据运行模式自动为低压电池、高压电池、空调供电,最大限度避免电池维护,电池电量消耗可以自动补充,防止过放导致电芯损坏,增加整车续航里程。
