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.
However, the cooling results are much more reliable. EV Batteries have specific operating ranges, which are critical for the battery life and performance. They are designed to operate at ambient temperature, which is between 68°F and 77°F (20°C and 25°C). A better control over the battery temperature improves their performance and life.
Some new cooling technologies, such as microchannel cooling, have been introduced into battery systems to improve cooling efficiency. Intelligent cooling control: In order to better manage the battery temperature, intelligent cooling control systems are getting more and more attention.
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. Introduction
LIBs can be heated using primary electric heating, heat pipe heating, and a combination. The battery has been tested under operating temperatures ranging is 10 °C. The performance of the thermoelectric solid-state heat pump and the heat pipe exceeds the other methods. Heating could be more evenly distributed if a heating pipe was used.
Liquid cooling has been successfully used in datacenters for years and more recently in some EV models such as the Tesla Model X, Model S, and Model 3, to name a few. Battery cooling methods will continue to be an important focus as performance of batteries improve even further.
