The invention discloses a method for controlling start-up battery charging, a battery manager, an electric vehicle and a storage medium, and the method comprises the steps: detecting that a vehicle enters a start-up battery charging mode; obtaining an initial voltage value and a DC output lower limit voltage value of the start-up battery; when the initial voltage value is larger than or equal to the DC output lower limit voltage value, controlling a DC/DC device to output a first voltage value so as to charge the start-up battery, the first voltage value being larger than the initial voltage value; and increasing the voltage value output by the DC/DC device every other preset time, and the increase amplitude is the preset voltage amplitude. According to the method, the battery manager andthe vehicle, the start-up battery is charged with the dynamic charging voltage, the lithium precipitation phenomenon caused by low-temperature charging can be avoided, the stability is improved, and the charging efficiency is considered.
本发明公开了一种控制起动电池充电的方法、电池管理器及电动车辆及存储介质,其中,该方法包括:检测到车辆进入起动电池充电模式;获取所述起动电池的初始电压值和DC输出下限电压值;当所述初始电压值大于等于所述DC输出下限电压值时,控制DC/DC装置输出第一电压值,以对所述起动电池充电,其中,所述第一电压值大于所述初始电压值;以及,每隔预设时间增大所述DC/DC装置输出的电压值,且增大幅度为预设电压幅值。本发明的方法、电池管理器和车辆,以动态充电电压对起动电池充电,可以避免低温充电出现析锂现象,提高稳定性,并兼顾充电效率。
