A battery thermal management system keeps batteries operating safely and efficiently by regulating their temperature conditions. High battery temperatures can accelerate battery aging and pose safety risks, whereas low temperatures can lead to decreased battery capacity and weaker charging/discharging performance.
In liquid-based battery thermal management systems, a chiller is required to cool water, which requires the use of a significant amount of energy. Liquid-based cooling systems are the most commonly used battery thermal management systems for electric and hybrid electric vehicles.
Liquid-based cooling systems are the most commonly used battery thermal management systems for electric and hybrid electric vehicles. PCM-based battery thermal management systems include systems based on solid-liquid phase change and liquid-vapor phase change.
For example, as temperature falls below -10°C, the performance of Li-ion batteries deteriorates severely , while at high temperature, these types of batteries are prone to uncontrolled temperature build-up . Hence there’s a requirement of using battery thermal management system in high voltage battery pack.
This thermal management approach maintained a stable heat preservation effect for standby battery packs outdoors. The thermal management system based both HP and TEC, controled the temperature rise of the battery surface at different discharge rates and maintained it within the ideal range.
In addition, refrigerant-based battery thermal management systems constitute a type of PCM-based battery thermal management system that is capable of removing high heat loads at high C-rate operating conditions compared to air-based and liquid-based battery thermal management systems.
