The invention discloses a method and device for determining the residual capacity of a battery and a nonvolatile storage medium. The method comprises the steps that voltage values of a plurality of battery cells included in a target battery and a temperature value of the target battery are obtained, and the target battery is located in the electric vehicle; determining a reference voltage value in the voltage values of the plurality of battery cells; according to the reference voltage value, the temperature value of the target battery and a predetermined battery capacity attribute table, the residual capacity value of the target battery is determined, the battery capacity attribute table comprises a plurality of temperature values, each temperature value in the plurality of temperature values corresponds to a plurality of voltage values, and the plurality of voltage values respectively correspond to a plurality of battery residual capacity values. The technical problem that the influence of environmental factors on the battery capacity is not comprehensively considered when the battery residual capacity is determined is solved.
本发明公开了一种电池剩余容量的确定方法、装置和非易失性存储介质。其中,该方法包括:获取目标电池包括的多个电芯各自的电压值,以及目标电池的温度值,其中,目标电池位于电动汽车内;在多个电芯各自的电压值中,确定参考电压值;根据参考电压值和目标电池的温度值,以及预先确定的电池容量属性表,确定目标电池的剩余容量值,其中,电池容量属性表中包括多个温度值,多个温度值中每个温度值对应多个电压值,多个电压值分别对应的多个电池剩余容量值。本发明解决了确定电池剩余容量时未综合考虑环境因素对电池容量造成的影响的技术问题。
