In an electric vehicle, a battery serves as the power source for its various operations. Lithium-ion batteries are preferred because of their excellent performance. A battery pack comprises multiple cells that undergo repeated charge-discharge cycles, resulting in temperature changes due to heat generation. The performance and longevity of the battery are sensitive to temperature variations. It is critical to maintain the pack temperature between 15°C and 45°C. In addition, the cell temperature gradient shall be limited to 5°C. In recent years, significant research in this field has led to the development of several innovative solutions. Among them, liquid-based thermal management systems have received considerable interest owing to their superior thermal control and their ability to meet the needs of today’s electric vehicles. This article presents the latest developments in liquid-based thermal management techniques. A brief discussion of battery preheating strategies for cold climates is also presented.
