Liquid cooling is the only remaining option that does not consume too much parasitic power, delivers cooling requirements, and fits compactly and easily into the battery pack. Tesla, BMW i-3 and i-8, Chevy Volt, Ford Focus, Jaguar i-Pace, and LG Chem’s lithium-ion batteries all use some form of liquid cooling system.
Choosing a proper cooling method for a lithium-ion (Li-ion) battery pack for electric drive vehicles (EDVs) and making an optimal cooling control strategy to keep the temperature at a optimal range of 15 °C to 35 °C is essential to increasing safety, extending the pack service life, and reducing costs.
Battery cooling is part of the vehicle's Battery Thermal Management System (BTMS). The BTMS includes the cooling and heating module, as well as the operating strategy, control system and thermal management software.
The article reviewed introductory physics, showing why liquid cooling could better control battery temperature. We reviewed the main types of cooling systems for the battery pack of electric vehicles and advanced topics such as phase change material (PCM) selection. We will close with a historical perspective.
This need for direct cooling arises due to the significant heat generated by the high current flowing into the battery during fast charging. Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues.
Therefore, the current lithium-ion battery thermal management technology that combines multiple cooling systems is the main development direction. Suitable cooling methods can be selected and combined based on the advantages and disadvantages of different cooling technologies to meet the thermal management needs of different users. 1.
