METHOD AND DEVICE FOR CALCULATING STATE OF CHARGE, VEHICLE AND STORAGE MEDIUM

A method, a device, a vehicle, and a storage medium for calculating state of charge of the battery are provided. The method is applied to a battery pack including battery cells and includes the following steps. Charge information of the battery cells is acquired, which includes a first state of charge and a second state of charge of the battery cells. A determination is made as to whether the charge information satisfies specified precision judging criteria. If the charge information satisfies the specified precision judging criteria, a target state of charge of the battery cells is determined based on the second state of charge. If the charge information fails to satisfy the specified precision judging criteria, the target state of charge of the battery cells is determined based on the first state of charge. When the charge information satisfies the specified precision judging criteria, the total state of charge of the battery pack is calculated on the basis of the second state of charge, which is more accurate than that calculated on the basis of the first state of charge, achieving a more accurate estimation of the total state of charge of the battery pack.
