Abstract

A battery safety evaluation apparatus according to one aspect of the present invention includes a battery characteristic estimator, a heat amount estimator and safety index calculator. The battery characteristic estimator estimates an estimation value of an inner state parameter of a first battery on the basis of data on voltage and current of the first battery measured in charging or discharging. The heat amount estimator estimates a heat amount of the first battery upon change of an external temperature on the basis of first reference data which is at least indicating relationship between a heat amount of a secondary battery and the external temperature and is set to correspond to the first battery on the basis of the estimation value. The safety index calculator calculates a safety index regarding a temperature of the first battery upon change of the external temperature on the basis of the estimated heat amount.
