Method and device for estimating remaining storable duration of storage battery and automobile

The invention provides a method for estimating the remaining storable duration of a storage battery. The method comprises the following steps: reading a first accumulative discharge capacity, a first accumulative charge capacity, a first remaining SOC and a first SOC precision of a vehicle before the last start; reading a second accumulative discharge amount, a second accumulative charge amount, a second residual SOC and a second SOC precision of the vehicle after the last flameout; if the first SOC precision and the second SOC precision meet the preset requirement, determining the maximum capacity of the vehicle when the storage battery is fully charged before the vehicle is started based on the read parameters; reading the current residual SOC of the storage battery, the current SOC precision, the dark current of the storage battery and the lowest starting electric quantity currently required by the vehicle when the vehicle is started this time; if the current SOC precision meets the preset requirement, the
