Abstract
A management device that manages a battery acquires an internal and external temperature difference saturation value of the battery, at a constant current, based on a current of the battery. The management device also acquires an internal and external temperature difference of the battery, based on the internal and external temperature difference saturation value of the battery that is acquired at the constant current. The management device also acquires the internal temperature of the battery, based on an external temperature of the battery and the internal and external temperature difference of the battery that is acquired.
