My 2018 Bolt, 46K, doesn't seem to cool the battery when it's parked, experiencing high ambient temperature unless it's actually plugged in, charging. we have experienced 105+ degrees this summer. Is there a relay or some switch that could be faulty, and replaceable for the home DIYer?
After a long, hot (90+F) drive and parked in a 100+F garage, the wall energy required to completely recharge was 20.168 kWh. Normal full recharge is 14.1-14.5 kWh. Yes, you could hear the AC running at least 50% duty cycle, cooling the battery for 5 hours. Nearly 6 kWh of cooling!
