= METHOD FOR ESTIMATING BATTERY CAPACITY AND METHOD FOR ESTIMATING BATTERY SOC =

'''Abstract''':
an object of the present disclosure is to provide a method for accurately estimating battery capacity, and a method for accurately estimating soc of battery based on the estimated battery capacity determined by such a method for estimating battery capacity. the method of the present disclosure for estimating battery capacity, comprises having a computer execute the following steps: (a) determining a specific internal resistance, in a prescribed provisional soc of 80% or more and a prescribed temperature, by charging at a prescribed charging speed for a prescribed time; and (b) determining an estimated battery capacity from the specific internal resistance based on a pre-specified first relationship between the specific internal resistance and battery capacity. the method of the present disclosure for estimating battery soc comprises, after step (b), having a computer execute determining an estimated amount of change in soc or an estimated soc after change associated with battery degradation.
