Capacity is not updated by battery management if temperature sensors report temperature below 15 degree Celsius.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW

Why 15 degrees? The car is garaged and while the battery temps are below 59 degrees Fahrenheit (about 15 degrees Celsius) today, it has been pretty mild here in South up until this weekend.

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.
