The invention discloses a battery remaining life value calculation method and device, and a storage medium. The battery remaining life value calculation method comprises the following steps: obtaining first charging and discharging data of a first battery; generating a first relation curve of the capacity change rate and the voltage according to the first charging and discharging data; calculating a first full charge capacity value of the first battery according to the first relation curve; and calculating the remaining life value of the first battery according to a preset relational expression between a full-charge capacity value and the remaining life value of the battery and the first full-charge capacity value. According to the invention, the residual life value of the lithium ion battery can be accurately calculated in the actual application scene of the lithium ion battery. 本申请公开了一种电池剩余寿命值计算方法及装置、存储介质，上述电池剩余寿命值计算方法包括以下步骤：获取第一电池的第一充放电数据；根据所述第一充放电数据生成容量变化率与电压的第一关系曲线；根据所述第一关系曲线计算所述第一电池的第一满充容量值；根据预设的满充容量值与电
