This paper describes construction of the Internal Temperature Model for NAS battery. NAS battery is paid attention to height of the energy density and easiness of maintenance in the field in the electric power system. The operation temperature of the NAS battery is high, and an internal temperature exceeds 300℃. To keep this temperature, heater has been introduced though the NAS battery is wrapped in the container where an insulated processing was done. Then it has aimed to reduce power consumption in the heater by paying attention to battery's heat radiation reaction when electricity is discharged, and designing the timing of the electrical charge and discharge, and to raise the combined efficiency. After the model with high accuracy is constructed, it is scheduled that the timing of the electrical charge and discharge is examined, and the best operating method is proposed.
