In addition, when a battery is discharged at a low discharge rate, it generates extremely low internal heat to maintain its temperature. Thus, the temperature of the battery decreased sharply after the preheating stopped, as shown in Fig. 7 (d). This result means that preheating is not effective to the batteries discharging at a low rate.
