The invention discloses a vehicle low-voltage energy management method and device, electronic equipment, a storage medium and a vehicle. The method is characterized by comprising the following steps: detecting whether a vehicle has a high-voltage power-on demand or not; when no high-voltage power-on requirement exists, a direct-current converter electrically connected with the power battery is turned off, the photovoltaic generator is controlled to supply power to a low-voltage electric appliance of the vehicle, and the direct-current converter, the photovoltaic generator and the storage battery are electrically connected with the low-voltage electric appliance of the vehicle after being connected in parallel; when a high-voltage power-on demand exists, the photovoltaic generator is controlled to stop supplying power to the low-voltage electric appliance, the direct-current converter is started, and the power battery is controlled to supply power to the low-voltage electric appliance through the direct-current converter. According to the invention, it is ensured that only the power battery or the photovoltaic generator supplies power at the same time, so that the storage battery is prevented from being damaged due to the fact that the photovoltaic generator needs to provide higher voltage when the power battery and the photovoltaic generator supply power at the same time.

    本发明公开车辆低压能量管理方法、装置、电子设备、存储介质及车辆。方法,其特征在于,包括:检测车辆是否有高压上电需求;在无高压上电需求时,关闭与动力电池电连接的直流转换器,并控制光伏发电器为车辆的低压用电器供电,直流转换器、光伏发电器以及蓄电池并联后与车辆的低压用电器电连接;在有高压上电需求时,控制光伏发电器停止为低压用电器供电,并启动直流转换器,控制动力电池通过直流转换器向低压用电器供电。本发明保证同一时刻仅有动力电池或者光伏发电器进行供电,因此,避免了动力电池与光伏发电器同时供电时,光伏发电器需要提供更高电压而损坏蓄电池。
