The update on the second generation of Nissan Leafs already happened in Britain and is now coming to the US.
The update on the vehicles has a reason. When needed to do long travels, the owners would fast charge he Nissan and use its capacity until it runs very low.
After that, with the charge running down a second or third time, the cars would get plugged in again, and the vehicles would go down to 50-kilowatt charge rate. The cars didn’t even fast-charged anymore after a while.
The vehicles would need a cool down before getting charged again.
This issue is what might drive customers away from Nissan Leafs, since its main competitor, Tesla, has several fast-charge stations across the US. Maybe a Model 3 suits better the extensive usage of the mile range and the battery.
