So it had been a hot entire Oct and 1st week Nov since I got my car (Sealion 7).
I was noticing about 85%+ efficiency during those hot days where it was 31 even at night.
Today the weather was 26 indicated when I started charging at about 6. The efficiency was about 90%.
Quite surprised a ~5 deg drop saw a ~5% diff. OK this is 1st time charging in this cooler weather. Anyone else seeing this effect?
