My Air has recently started cutting back the rate of charge while at home. I have the Lucid 80 amp charger, wired to a 100 amp circuit. It starts out at 80 amps, then over time (I haven't measured yet since it's usually overnight), it cuts down to 31-ish amps. Is something overheating, or did a software update push out some sort of "slow it down to not use A/C to cool things"? FWIW, it was always 80 amps before, I just started noticing recently that it wasn't finished in the morning when it would normally only take 3 hours.
