Batteries have emerged as energy storage device in EVs. For EVs batteries, the key threat is temperature. Since the battery-charging trend is shifting towards fast charging, the new thermal challenges are going to arise in EVs battery pack. Therefore, an efficient thermal management is required to ensure the performance and safety.
The design of thermal management systems for cylindrical lithium-ion battery packs involves specific criteria to optimize performance and safety. First and foremost is the need for effective temperature control to maintain the battery within its optimal operating range, preventing overheating and potential safety hazards.
Battery thermal management systems (BTMS) aremethods employed to keep the temperature in a battery pack within a fixed range – ideally between 20 and 40 °C – avoiding excessive fluctuations and maintaining an even temperature from cell to cell.
To tackle these issues, lithium-ion batteries can be fitted with a battery management system (BMS) that oversees the regular functioning of the battery and optimizes its operation. Ensuring the safe functioning and extending the lifespan of a battery necessitates the presence of an efficient thermal management system.
Regarding future developments and perspectives of research, a novel concept of thermal management of battery packs is presented by static devices such as Thermoelectric Modules (TEMs). TEMs are lightweight, noiseless, and compact active thermal components able to convert electricity into thermal energy through the Peltier effect.
Hence, battery thermal management is not only essential to maintain a healthy operating range but also important to achieve uniformity on temperature distribution for a longer lifetime of a battery pack. Heat generation is inevitable inside the battery and battery pack.
