As electric vehicles (EVs) are gradually becoming the mainstream in the transportation sector, the number of lithium-ion batteries (LIBs) retired from EVs grows continuously. Repurposing retired EV LIBs into energy storage systems (ESS) for electricity grid is an effective way to utilize them.
The thermal conductivity of the battery is anisotropic, different directions have different thermal conductivity values. iv. The adjacent LIBs are assumed to be in tight contact, so contact thermal resistance is not considered between adjacent LIBs. Table 5 summarizes the thermophysical properties of LIBs in the ESS. Table 5.
Of the several types of batteries, lithium-ion is a type of battery that is generally used in electric vehicles. When an electric vehicle operates, the battery will produce heat, when the battery temperature is high, this can result in the performance of the battery decreasing and can even be exploded.
Moreover, for every 1°C increase within the 30-40°C range, battery lifespan diminishes by roughly two months [38, 39], underscoring the impact of exceeding operational temperature limits on the acceleration of lithium-ion batteries’ aging processes.
Under the conditions set for this simulation, it can be seen that the liquid-cooling system can reduce the temperature rise of the battery modules by 1.6 K and 0.8 K at the end of charging and discharging processes, respectively. Fig. 15.
