Battery Thermal Management

Battery thermal management system (BTMS) is a crucial component to electric vehicles. The performance and life of Li-ion battery, which is the widely used battery chemistry for electric vehicles is very sensitive to its operating temperature (15-50°C). Hence, BTMS have the critical role in maintaining the batteries in the desired temperature range during various operating conditions. Thermal management of high energy density batteries and during fast charging is a potential challenge to thermal engineers. Compared to single cooling, as flow boiling has high heat transfer capacity due to latent heat, an improved two-phase minichannel heat sink has been developed for cooling high energy density batteries.
