Zusammenfassung: | The invention provides a method and a device for estimating the SOC of a battery, a storage medium and a vehicle. The method comprises the steps of: obtaining the initial SOC value of the initial charging and discharging stage of a battery through an open-circuit voltage method; acquiring current data of charging and discharging of the battery, and performing ampere-hour integration according to the current data based on the rated capacity of the battery to obtain a theoretical SOC variation; and detecting real-time battery capacity influence parameters, obtaining a capacity correction coefficient according to the battery capacity influence parameters, correcting the theoretical SOC variation according to the capacity correction coefficient to obtain an actual SOC variation, and obtainingan SOC estimated value of the battery according to the initial SOC value and the actual SOC variation. According to the method and the device for estimating the SOC of a battery, the capacity correction coefficient is obtaine |
