The optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.
The target temperature (T tgt) of heating is often different, such as 60 °C , 29.1 °C , 10 °C , and 5.6 °C , which is determined by the performance of the battery , .
The temperature of the battery instantly rises to 796.5 °C. After reaching the T onset temperature, the battery diaphragm is melted, and the independent components in the battery come into contact with each other, resulting in an internal short circuit.
Recent advances include the use of PCM and forced-air cooling, improving temperature regulation and battery performance . Hybrid thermal management systems have been developed, offering more efficient cooling for LIBs.
The cooling efficiency depends on the L/D ratio; at L/D = 36.1 gives a better performance. Increasing the flow rate enhanced the temperature reduction of the battery. Also, lowering the fluid's inlet temperature significantly reduces the battery pack's temperature. Need to optimize the inlet flow rate and temperature.
Heating with a spring enhances the heat transfer efficiency between the battery and the spring, resulting in more uniform internal heating and a lower triggering temperature for TR. Liu et al. observed that cylindrical heating rods achieve an efficiency of approximately 15% in heating the battery.
