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.
It has been observed that both active and passive cooling methods significantly reduce battery temperatures and maintain temperature uniformity. The air-based BTM system is suitable for batteries with low charging and discharge ratings due to its relatively lower heat transfer rate between air and the battery.

To reduce the energy consumption of batteries during the heating process of EVs, researchers have proposed burner heating methods that utilize alternative energy sources.
Using experimental data, the three-dimensional thermal model of a battery with TEC was developed and calibrated by Liu et al. . Implementing TEC cooling decreased the maximal battery temperature from 31.7 °C to 26.1 °C. Negi and Mal presented a technique for cooling batteries that used Thermoelectric cooling driven by PV with MPPT.
Findings indicate that lower convective heat transfer coefficients, higher latent heat of PCM, and increased PCM thickness lead to decreased battery pack temperature and increased temperature difference. Higher HP equivalent thermal conductivity or lower start temperatures also contribute to lower battery pack temperatures.
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 .
