The features and the performance of each preheating method are reviewed. The imposing challenges and gaps between research and application are identified. Preheating batteries in electric vehicles under cold weather conditions is one of the key measures to improve the performance and lifetime of lithium-ion batteries.
Due to low thermal conductivity and high space requirement, air preheating is only suitable for early generation EVs with low energy density batteries. At the moment, liquid preheating is the most commonly used method since it has demonstrated good preheating performance and consistent temperature distribution.
Therefore, a battery thermal management system (BTMS) for controlling the operating temperature of batteries plays a critical role in improving the performance of batteries . Currently, most of review studies on BTMSs focus on problems associated with high temperatures to address cooling or heat dissipation.
With the continuous development of Evs (electric vehicles) and new energy, smart BESS (battery energy storage system) charging stations came into being, and the EV battery testing technology is particularly important.
Preheating the batteries before charging/discharging is important to maintain the high performance of lithium-ion batteries and hence EVs in cold weather conditions.
In the context of the vigorous development of big data, battery testing systems need big data technology to carry out battery safety protection and early warning while making an accurate assessment of battery health and life.
