The invention discloses a charging method and device of a storage battery and a computer readable storage medium, and relates to the technical field of new energy. Vehicle data are acquired according to a preset period, and whether a voltage value is lower than a preset threshold value is judged; if yes, outputting alarm information to a user, and receiving a user instruction; and if the instruction is a charging instruction, starting the VCU, the BMS and the DCDC so as to send a high-voltage instruction to the BMS through the VCU and output a high voltage to the DCDC through the BMS to obtain a charging voltage, and charging the storage battery according to the charging voltage. Visibly, when the voltage value of the storage battery is lower than the preset threshold value, the alarm information is output, and when the instruction of the user is the charging instruction, the VCU, the BMS and the DCDC are started to charge the storage battery, so that the situation that the user can find that the electric quantity of the storage battery is insufficient only when starting the vehicle is avoided, and meanwhile, the VCU, the BMS and the DCDC are started only during charging, so that power consumption can be reduced.
本申请公开了一种蓄电池的补电方法、装置及计算机可读存储介质,涉及新能源技术领域。通过按照预设周期获取车辆数据,判断电压值是否低于预设阈值;若是,输出报警信息至用户,并接收用户指令;若指令为补电指令,则启动VCU、BMS以及DCDC,以通过VCU发送上高压指令至BMS,并通过BMS输出高压至DCDC,以得到补电电压,并根据补电电压对蓄电池补电。可见,在蓄电池的电压值低于预设阈值时输出报警信息,并在用户的指令为补电指令时启动VCU、BMS以及DCDC以对蓄电池进行补电,避免了用户启动车辆时才能够发现蓄电池电量不足的情况,同时,在补电的时候才开启VCU、BMS以及DCDC可以减少功耗的产生。
