Enhancing temperature uniformity and maintaining the operational temperature of the battery within a suitable range are the principal objectives of BTMS in EVs.
These expressions are developed using the established energy, electrochemical, heat generation and transfer equations with the boundary constraints of the working environment. Methods like computational fluid dynamics (CFD) are essential to assess the thermal characteristics of a Li-ion battery.
Thus, lithium-ion batteries must be operated within a temperature range of 15 – 35°C with a maximum temperature difference of 5°C. Therefore, a thermal management system is essential in controlling batteries in an optimal range of temperatures and dealing with corresponding issues.
4.1. Theoretical modeling approach: The thermal modeling of a Li-ion battery is carried out using mathematical expressions and descriptions based on the specific thermal conditions, thus helping to predict the performance of the system.
In comparison to other PCMs types, organic materials, notably PA wax is the most commonly adopted to manage the battery thermal energy since it has high chemical stability, high latent heat, low cost, and corrosion resistance. Their drawbacks include the fact that they are not thermally conductive, prone to leaks, and are flammable.
Temperature uniformity of battery was higher for liquid-circulated compared with liquid-filled. Under 5C charge/discharge operations, these techniques reduced the battery pack's temperature non-uniformity and Tmax to less than 2.01 K and 305.13 K, respectively.
