The embodiment of the invention provides a battery charging method and device applied to a vehicle, electronic equipment, a storage medium and a program product. The method comprises the following steps: detecting the voltage state of a storage battery in the vehicle in the process of controlling a photovoltaic module in the vehicle to charge a power battery in the vehicle; when it is determined that the voltage state of the storage battery represents that the voltage of the storage battery is smaller than a first preset threshold value, the whole vehicle step-down DC/DC is controlled to be started, so that voltage lines of the power battery, the whole vehicle step-down DC/DC and the storage battery are conducted, and the power battery charges the storage battery through the whole vehicle step-down DC/DC. And the situation that the vehicle cannot be normally started due to insufficient electricity caused by continuous discharging of the storage battery is avoided.

    本申请实施例提供一种应用于车辆的电池充电方法、装置、电子设备、存储介质及程序产品。该方法包括:在控制车辆中的光伏组件向车辆中的动力电池充电的过程中,检测车辆中的蓄电池的电压状态;在确定蓄电池的电压状态表征蓄电池电压小于第一预设阈值时,控制整车降压DC/DC开启,以使动力电池、整车降压DC/DC、蓄电池三者的电压路线导通,使得动力电池通过整车降压DC/DC向蓄电池充电,该方法用以达到提高光伏发电利用率的同时,避免蓄电池持续放电造成亏电,以致车辆无法正常启动情况的发生。
