The invention relates to an electric vehicle power supply management method, device and equipment and a storage medium. The method comprises the steps of starting timing while charging a storage battery, and storing the formed timing information in a database, respectively detecting and obtaining the voltage and current of each single battery in the storage battery when the storage battery is charged, calculating and obtaining the real-time electric quantity of each single battery according to the timing information in the database and the obtained voltage and current of each single battery, and discharging part of the single batteries according to the current real-time electric quantity condition of each single battery until the electric quantities of the single batteries are basically kept consistent. The method has the technical effects that the electric quantity difference among the single batteries in the charging process of the storage battery is relatively small, and the overallbalance of the battery pack is improved, so that the service life of the lead-acid storage battery is prolonged.

    本申请涉及一种电动车电源管理方法、装置、设备及存储介质,其中方法包括:在对蓄电池进行充电的同时,启动计时并将形成的计时信息存储在数据库中;在对蓄电池进行充电时分别检测并获取蓄电池内每一单体电池的电压及电流;根据所述数据库中的计时信息以及获取到的每一单体电池的电压及电流计算并得出每一单体电池的实时电量;根据每一所述单体电池当前的实时电量情况对部分单体电池进行放电,直至各单体电池之间的电量基本保持一致。本申请具有的技术效果是:蓄电池充电过程中各单体电池之间的电量差距较小,提升了电池组的整体均衡性,从而提升了铅酸蓄电池的使用寿命。
