A nonaqueous electrolyte secondary battery is a battery system for an electric vehicle which prevents high rate deterioration. An integrated evaluation value which is a deterioration index value of high rate deterioration is subjected to correction processing reflecting a recovery behavior of the high rate deterioration during charging/discharging deactivation in a battery deactivation period. The correction processing is executed according to a relaxation coefficient indicating the degree of relaxation of deviation of an ion concentration each time a given time elapses when the battery deactivation period ends. The relaxation coefficient is set variably such that, when a time length of the battery deactivation period is short, the degree of relaxation of deviation of the ion concentration for the given time becomes greater than that when the time length is long.
