I suspect Nissan's engineers knew that 1) degradation is really slow at cold temperatures and
2) it is almost impossible to get good data if chemistry is cold (we know that you get less juice
if battery is below optimal temperature).
So if there is 5 battery temp bars it should update once in a while.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW
