Are the newer generation Leafs still air cooled batteries?
Still air cooled Passive cooling and air cooling are not the same thing. Describing the Leaf as air cooled, even worse suggesting that the pack is cooled as the car moves, as though there isn''t sealed cells inside sealed modules inside a sealed pack with a plastic airflow diverter under the pack preventing air from flowing over the bottom of the pack is misleading. It radiates heat

Are air cooled batteries a good idea?
Yup, the world has come full circle, and air-cooled batteries are about to come into vogue. The core reason for using air instead of liquid to cool the battery is to minimise weight and, importantly, reduce the number of parasitic systems drawing power away from the business of propelling the vehicle.
Why do electric car batteries need to be cooled?
Electric car batteries need to be cooled at high outside temperatures, to keep them within the optimum temperature range. (Photo: Adobe Stock) This is because of the composition of the cells in the battery, which are a chemical mixture of lithium, cobalt or nickel, graphite, copper, and aluminium.
How is a car battery cooled?
The battery is cooled by one or more cooling plates through which the coolant flows. The coolant heats up and transfers the heat to another fluid in a heat exchanger. At low ambient temperatures and low cooling capacity, the heat can be transferred to the ambient air via an ambient heat exchanger in the front end of the vehicle.
Do batteries need to be cooled?
Batteries, like combustion engines, need to be cooled when operating. Traditionally this is done with liquid. The prevailing method of battery cooling is a ‘jacket’ which encases the entire unit and pumps liquid around it to keep temperatures in check.
