Lithium-ion (Li-ion) batteries, the most commonly used energy storage technology in EVs, are temperature sensitive, and their performance degrades at low operating temperatures due to increased internal resistance.

Fig. 14. (a) Charge time of the batteries in different stages at different temperatures and (b) total charge time of the batteries at different temperatures. Preheating is one of the best ways to enable the battery switch to super-charge mode as quickly as possible and reduce the charging time of the battery system.
With the increase of preheating rate, the time of trickle charge stage is greatly reduced and that of super-charge increases slightly. It is because that the faster the preheating rate, the sooner the battery system reaches the switch temperature of super-charge.
When the SC capacity ratio between SC and battery pack increased to 22.5 F/Wh and the ECPCM resistance decreased to 0.05 Ω, the preheating rate of the battery system reached 69.5 °C/min. In addition, preheating can increase the temperature of the battery, allowing the battery system to charge at a higher current, reducing charging time.
Compared with the benchmark electric car model, the battery energy consumption can be reduced by 36% at −30 °C. In addition, an annual analysis shows that a 30 kg heat storage tank can reduce the average annual consumption of battery by up to 20 Wh/km or 12%. Fig. 6. Block diagram of the HVAC system with a sensible heat storage tank .
By adjusting SC capacitance and ECPCM resistance, the preheating rate of the battery system can reach 69.5 °C/min, and the temperature difference is less than 5 °C. Moreover, the pulse current of SC can reduce the temperature difference inside the battery within 5 °C.
Therefore, preheating the battery system to the super-charge temperature (20 °C in this system) as fast as possible can greatly reduce the charging time and increase the charging speed of the battery system. Fig. 15.
