The battery used in the model is a li-ion battery with a length of 65 mm, width of 18 mm and a height of 140 mm as displayed in Fig. 8 (b). The heat generation model of the li-ion battery is based on discharge rates between 0.5C to 2.5C with 0.5C increments while the air inlet velocity was set at 3.0 m/s and 3.5 m/s to ensure results accuracy.
To increase the heating rate, increasing the heating current was regarded as more effective than increasing the AC heating frequency, but this could lead to Li-ion plating and could reduce battery life. In addition, the electrode material and electrolyte can be optimized .
The SP heating at 90 W demonstrates the best performance, such as an acceptable heating time of 632 s and the second lowest temperature difference of 3.55 °C. The aerogel improves the discharge efficiency of the battery at low temperature and high discharge current.
The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance. The temperature uniformity is poor due to the narrow space, and the temperature of the water heating the battery is also decreased with the increase of the distance the water flows through .
After heating the bottom of the battery pack with PTC material for 3 hours, the average temperature of the external cells was 2.57°C, while the temperatures of the internal cells were －2.63 and －2.09°C.
Each battery thermal management system (BTMS) type has its own advantages and disadvantages in terms of both performance and cost. For instance, air cooling systems have good economic feasibility but may encounter challenges in efficiently dissipating heat during periods of elevated thermal stress.
