The invention provides a battery SOC determination method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining a first voltage value of a target battery and a second voltage value of the target battery, the first voltage value being a voltage value of the target battery when the target battery is powered on at the current time, and the second voltage value being a voltage value of the target battery when the target battery is powered off at the last time; the first voltage value and the second voltage value are compared, a comparison result is obtained, a corresponding target mapping relation is determined at least according to the comparison result, and the target mapping relation is the mapping relation between the voltage value of the target battery and the SOC of the target battery; according to the first voltage value and the target mapping relation, the SOC of the target battery corresponding to the first voltage value is determined as the target SOC of the target battery, and the target SOC is the SOC of the target battery when the target battery is powered on at the current time. According to the method, different OCV curves are adopted to determine the current SOC according to different working conditions of the battery, so that the estimation of the SOC is more accurate.
