I Have a 2013. I am doing some experimenting with battery temperature and I think the cabin air exhausts down into the Battery area.
If this is true, I am amazed that someone has not found it before in order to cool the battery and therefore prolong its life.
What I did was to turn on the AC set at 73degF with the fan running full. It is set to outside air input and then I rolled all the windows up. I did this with an L2 charge happening at the same time.
First I checked Leafspy. 4kw going into the charger. 2.5kw going into the battery. so we have 1.5kw going into the AC. After 15 minutes or so, the AC power drops to about 0.75kw. Also I see T1 is the lowest temp. Without AC T1 is normally the highest.
Then look for warm and cool airflow around the car.
The radiator fans are running. Hot air is blowing out over the front tires.
The cabin blower is running. it is sucking air in at the bottom of the windshield.
The cool air exhausting from the cabin appears to be coming out around the battery shield.
I have data logging going on LeafSpy so later I will chart the temps and see if the battery is being cooled.
This is important Because this gives us a tool to cool the battery during charging and therefore increase the life of the battery.
Has anyone else seen this?
Am I crazy, or has this been available but Nissan has not given us instructions on how to improve the battery life?
Thanks,
Dan
