The invention relates to a method, system and device for preventing power shortage of a storage battery and electronic equipment, the method for preventing power shortage of the storage battery is applied to a vehicle control unit, the vehicle control unit is connected with a battery management system and a direct current converter through a high-voltage bus, and the method comprises the steps that whether the power utilization state of a vehicle meets a preset high-voltage power supply condition or not is determined; if the power utilization state of the vehicle meets the high-voltage power supply condition, the battery management system is controlled to output a high-voltage electric signal to a high-voltage bus; and controlling the direct-current converter to convert the high-voltage electric signal into a low-voltage electric signal so as to supply power to a low-voltage electric load connected with the direct-current converter. The embodiment of the invention can ensure that the storage battery is fully charged all the time under the condition that the power battery has electricity, reduces the charging and discharging times of the storage battery, prolongs the service life of the storage battery, avoids the conditions that the user cannot use the vehicle and needs to call for rescue due to the lack of electricity of the storage battery, and is convenient for the user to use.

    本发明涉及一种防止蓄电池亏电的方法、系统、装置及电子设备,防止蓄电池亏电的方法,应用于整车控制器,整车控制器通过高压总线与电池管理系统及直流转换器连接,方法包括:确定车辆的用电状态是否满足预设的高压供电条件;若车辆的用电状态满足高压供电条件,控制电池管理系统向高压总线输出高压电信号;控制直流转换器将高压电信号转化为低压电信号,以为与直流转换器连接的低压用电负载供电。本申请实施例可以保证在动力电池有电的情况下,蓄电池一直处于满电,减少蓄电池充放电次数,延长蓄电池寿命,并规避由于蓄电池亏电导致用户无法用车,需要呼叫救援的情况,便于用户使用。
