PROBLEM TO BE SOLVED: To provide a usage and a system of nonaqueous electrolytic battery capable of obtaining a sufficient performance in output under a low-temperature atmosphere. SOLUTION: Charging/discharging operation is performed after a temperature rise in battery by applying a voltage accompanied by a pulsation flow over 100 mV in peak-to-peak value and 1 Hz in frequency, when a battery temperature is lower than a predetermined temperature or a battery impedance is larger than a predetermined setting value. Under this condition, the time can be shortened for rising the temperature, and the increasing impedance can be suppressed when repeatedly performing temperature rise by means of the operation. An especially effective result can be expected when applying a nonaqueous electrolytic material using a lithium titanate to a negative electrode or to a battery system using the nonaqueous electrolytic material.
