The preheating strategies need to be further explored in a battery module/pack level since cell temperature homogeneity in a pack is critical to the overall performance of the battery pack and would affect its aging processes.
The CHE, with its working fluid heated by hot exhaust gas, can warm up the battery pack. Later, Seo et al. systematically investigated the heat transfer characteristics of this integrated heating system by considering factors such as heat exchanger effectiveness, heat transfer rate, temperature distribution, and fluid flow characteristics.
A single heating system based on MHPA can heat battery packs from −30°C to 0°C within 20 minutes and the temperature distribution in the battery pack is uniform, with a maximum temperature difference of less than 3.03°C.
Then the warm air could be sent to the battery pack by fans to heat the low-temperature batteries. The battery pack can be heated from −15 °C to 0 °C in 21 min. Song et al. experimentally validated the effectiveness of air heating using an external power source.
The batteries can be then warmed up to a chargeable temperature by the HVAC system through ventilating warm air to the pack. In the battery preheating system, heating efficiency plays a crucial role in determining the heating performance.
A Battery Thermal Management System, or BTMS, helps to maintain a battery pack at its optimal temperature range of 20 o to 45 o C regardless of ambient temperature. For each vehicle design, the required performance and cycle life of the battery pack will be considered to determine the specific set point for the battery pack temperature.
Considering the different needs for pre-heating battery packs in different usage scenarios, the impact of pre-heating methods on the battery pack service life and power …
