According to the battery charging control method in the embodiment of the invention, pre-charging timing is triggered when the vehicle is dormant, when the pre-charging timing duration reaches the charging detection time threshold value, the first battery voltage parameter and the second battery remaining capacity parameter are obtained, and the charging state of the first battery is determined based on the preset charging state judgment rule; if the charging state is a to-be-charged state, performing single charging on the first battery based on a preset charging duration, after the single charging is completed, re-determining the charging state of the first battery, and circularly charging the first battery until the charging state is that the electric quantity is sufficient; according to the method, when the vehicle is in the dormancy state, the charging demand is periodically detected, if charging is needed, the first battery is controlled to be charged, circulating charging is carried out within the preset time, over-temperature damage to the first battery caused by single-time charging temperature rise can be avoided, and the residual electric quantity parameter of the second battery in the circulating charging process can be detected; and excessive loss of charging electric energy of the second battery is avoided.

    本发明实施例中的电池补电控制方法,通过车辆休眠时触发进行预补电计时,当预补电计时时长达到补电检测时间阈值,获取第一电池电压参数和第二电池剩余电量参数,并基于预设补电状态判定规则确定第一电池的补电状态,若补电状态为待补电,则基于预设补电时长对第一电池进行单次补电,当单次补电完成后,重新确定第一电池的补电状态,循环对第一电池进行补电,直至补电状态为电量充足;本方法在车辆休眠时,周期性检测补电需求,若需要补电则控制对第一电池进行补电,并以预设时间进行循环补电,可以避免单次充电温度上升造成的第一电池的过温损害以及在循环补电过程中对第二电池剩余电量参数进行检测,避免第二电池充电电能的多余损耗。
