Some of the most advanced battery thermal management systems combine active and passive cooling methods. These hybrid systems allow for maximum efficiency while consuming less energy. For example, Rivian, a growing EV manufacturer, is considering using hybrid cooling systems for its fleet of trucks and SUVs.
Today’s technology allows a more efficient use and control of the thermal energy in electric cars. Temperature management is optimized between components such as the battery, the HVAC system, the electric motor, and the inverter. This is done using what is called a Battery Thermal Management System.
Consequently, the type of battery has a big impact on battery thermal management. One of the main functions of a battery thermal management system is to extract heat from the battery to prevent the degradation of its components as well as thermal runaways.
Effective thermal management can extend the life of your EV’s battery by preventing it from getting too hot or cold. For instance, electric vehicle manufacturers like Tesla use liquid cooling systems to maintain the temperature and extend the battery’s lifespan.
Each battery thermal management system (BTMS) type has its own advantages and disadvantages in terms of both performance and cost. For instance, air cooling systems have good economic feasibility but may encounter challenges in efficiently dissipating heat during periods of elevated thermal stress.
Types of battery thermal management systems. Battery thermal management systems are primarily split into three types: Active Cooling is split into three types: The cell or cells are held in an enclosure, air is forced through the battery pack and cools the cells.
