The invention relates to a low-voltage storage battery charging method and device and a medium, and relates to the technical field of new energy automobiles. The method comprises the following steps: in an OFF electric fortification state of a whole vehicle, detecting the real-time electric quantity of a low-voltage storage battery by an electric quantity sensor, and judging whether the real-time electric quantity is lower than an electric quantity threshold value or not; if yes, the electric quantity sensor awakens a main node area controller; if the electric quantity sensor successfully awakens a main node area controller, and when the main node area controller detects that the real-time electric quantity is lower than an electric quantity threshold value, the main node area controller awakens a whole vehicle network and synchronously sends a power supplementing request; the whole vehicle controller judges whether the whole vehicle meets a high-voltage condition or not based on the power supply request; if yes, the vehicle control unit sends an upper high voltage request signal; and after the whole vehicle is in high voltage, the low-voltage storage battery is charged. It is ensured that the low-voltage storage battery in the vehicle parked for a long time is not lack of electricity, and irreversible damage to the low-voltage storage battery caused by over-discharge of the low-voltage storage battery is prevented.

    本公开涉及一种低压蓄电池补电方法、装置及介质,涉及新能源汽车技术领域。该方法包括:在整车OFF电设防状态下,电量传感器检测低压蓄电池的实时电量,且判断所述实时电量是否低于电量阈值;若是,所述电量传感器唤醒主节点区域控制器;若所述电量传感器成功唤醒主节点区域控制器,所述主节点区域控制器检测到实时电量低于电量阈值时,所述主节点区域控制器唤醒整车网络,且同步发送补电请求;整车控制器基于所述补电请求判断整车是否满足上高压的条件;若满足,所述整车控制器发送上高压请求信号;在整车上高压之后,对低压蓄电池进行补电。本公开确保长时间停放的车辆内的低压蓄电池不亏电,且防止低压蓄电池过度放电对低压蓄电池造成不可逆损害。
