Free QuoteQin et al. depicts the thermal performance of a battery under active mode using forced-air cooling in PCM based thermal management system and shows superior performance with a maximum temperature of 16°C even at high charge/discharge current rate.
At a temperature difference of 150°C, the cost of TEG could rival the typical cost of fossil fuels, indicating that thermoelectric power generation can be conducted at a reasonable cost. Furthermore, compared to PV panels, TEG exhibits an attractive cost profile when considering the capacity factor [ 37 ].
Passive thermal management of battery systems can be achieved through passive thermal energy storage (TES) using phase change materials (PCMs) eliminating demand for additional energy consumption. Organic PCMs are commonly preferred for battery thermal management systems, as indicated in the literature .
Ideal conditions for operating Lithium-ion batteries are between -15°C to 40°C as shown in Fig. 1, and the temperature difference between cells should lie within 5°C, . Hence there is a need to develop an appropriate thermal management system for safely working of an electric vehicle with high efficiency.
The optimised design of the thermoelectric generator was designed, assembled and tested under real conditions and experimental data was collected. The findings show that 4.6 W of average electrical power is generated during the test cycle with an efficiency of 2.38%. The experimental evidence is used to verify the numerical model.
