Abstract: A method and a device for acquiring a battery capacity, a storage medium, and a server are provided. The method includes: acquiring multiple initial charging parameters when a current charging process of a vehicle battery is effective charging, where the effective charging means that the range of variation in state of charge (SOC) of the battery covers a preset SOC range, and the minimum charging temperature of the battery is greater than or equal to a preset temperature threshold; periodically acquiring multiple actual charging parameters of the battery and a current number of effective charging times corresponding to the current charging process; and acquiring, according to the multiple initial charging parameters, the multiple actual charging parameters and the current number of effective charging times, a predicted battery capacity of the battery in a next effective charging process.
