Onward and upward: Nissan Leaf version 2 reviewed

Posted on

Some EV enthusiasts have been quick to lay the blame on Nissan’s passive, air-cooled battery design, because most rival EVs incorporate active thermal management of the battery – cooling each cell with air or liquid circulated by a fan or pump. They suspect that the new 40kWh battery is in danger of overheating when subjected to high-speed running followed by rapid recharging without a break, and that the Leaf’s monitoring software is stepping in to protect the lithium-ion cells by throttling back the flow of charge.

Other explanations are possible, such as undetected software errors or unforeseen incompatibilities. A Nissan spokesperson confirmed that the company is in touch with Porterfield and other affected owners to investigate their experiences.
