Abstract: 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.

Abstract: An evaluation value is calculated based on a history of currents in order to quantitatively evaluate unevenness of an ion concentration in a non-aqueous electrolyte of a secondary battery. An integrated evaluation value for each of the discharging side and the charging side are calculated. When the integrated evaluation value exceeds a positive threshold value, discharging of the secondary battery is restricted, and when the integrated evaluation value exceeds a negative threshold value, charging of the secondary battery is restricted.

Abstract: An electric vehicle includes: a wheel drive motor; an inverter that supplies electric power to the motor; a pump that delivers refrigerant to the motor and the inverter; and a controller that controls the pump. When a main switch of the vehicle is at an ON position, the controller limits the pump output at or below a predetermined pump output upper limit value, and, when the main switch is switched to an OFF position while travelling, the controller drives the pump at an output higher than the pump output upper limit value irrespective of the pump output upper limit value.
