The invention relates to an SOC calculation method, system and device considering a battery state and a storage medium, and the method comprises the following steps: determining the state of a target battery based on the vehicle speed, gear, voltage and current data; calculating an instant SOC value corresponding to the target battery based on different states of the target battery; and performing temperature compensation on the instant SOC value of the target battery to obtain a final SOC value of the target battery. According to the method, accurate calculation of the initial SOC value of the new battery is facilitated, the accuracy of the SOC in the abnormal state of the single battery can be ensured, meanwhile, the influence of the temperature on the battery is considered, the accuracy of the SOC is further improved, the SOC gain is adjusted at different temperatures, the control process is optimized, and the service life of the battery is prolonged. Therefore, the method can be widely applied to the technical field of battery management systems.

    本发明涉及一种考虑电池状态的SOC计算方法、系统、设备和存储介质,包括以下步骤:基于车速、挡位、电压和电流数据,确定目标电池所处状态;基于目标电池的不同状态,计算得到目标电池所对应的即时SOC值;对目标电池的即时SOC值进行温度补偿,得到目标电池的最终SOC值。本发明便于新电池初始SOC值的准确计算,并且还可以确保单体电池异常状态下SOC的精准,同时考虑了温度对电池的影响,进一步提高了SOC的准确性,在不同的温度下调节SOC增益,从而优化控制过程,延长电池寿命。因此,本发明可以广泛应用于电池管理系统技术领域。
