And because of this, electric vehicle manufacturers should take note.
If only for a city only car that you mostly charge at home, don't do roadtrips with multiple fast charges in short period of time you may get away with passive cooling. And if you don't live in a hot climate. But those are too many IFs.
That describes our use case pretty well (for a 2-car household) and we’ve been quite happy with the 26K miles we put on our Nissan LEAF in MA over a coming up on 10 year period.
Charged at home >50% of the time and pre-pandemic on the 6.6kW chargers at work. I can only recall one attempt we made at a beyond single battery trip, using an EVGo DC charger at the mid-point. I can say it worked, but subsequent trips to that same location were in the ICE car, so take of that what you will.
The car is now 80+% charged at home and is a city/nearby suburb runabout (and used for more trips, albeit not more miles, than the other ICE/hybrid).
It still has about 85% of its original battery capacity, which means we charge it about once a week, which works just fine for us.
That also works for me for the second car. I also am awaiting Leaf delivery with 27k km on odo. however I did not expect battery to loose 15% of its capacity over 26k miles (which is 42kkm)
It is healthy to know how to maintain car battery. I will probably charge the battery to ~80% except when I need more range.
It’s also 10 years, which is a factor in degradation as well, not just cycles or distance.
It’s down 1 bar (of 12) and that was 2 years ago, so the 85% is estimated, but is within -0% to +4%. I have a LEAF Spy but haven’t checked it a long time.
Wasn't that how the Nissan Leaf's used to be setup, with passive cooling? I know it greatly affected their range in warm climates. I think they now switched to active cooling.
