Air cooling is further divided into natural and forced air cooling; fans produce airflow in forced air cooling, whereas no fans are used in natural air cooling. The advantages of using air cooling for Li-ion battery packs are related to its favorable features, such as being cost-effective, less weight, and less complex thermal solutions [ 83 ].

According to the US National Renewable Energy Laboratory, the optimal temperature range for lithium-ion is between 15 °C and 35 °C. An ambient temperature of about 20°C or slightly below ("room temperature") is ideal; if a battery operates at 30°C, its lifetime is reduced by 20 percent. At 40°C, the losses in lifetime approach 40 ...
