We are told that one of the main reasons to keep the car plugged in at home is to assure that the battery thermal management system can activate when ambient temps are too high or low, to keep the batteries healthy for the long term. My question is: at what temperatures does the battery cooling or heating kick in? I know I've read posts where folks were reporting some significant noise from the cooling system in summer.
Since this recommendation (the good ol' "a plugged in EV is a happy EV") is not about plugging in when charging, but keeping it plugged in, I've been surprised to have never heard the thermal management kick on in winter, with garage temps usually in the 20s, sometimes in the teens or perhaps a tad lower. And for the past two days my car was sitting in 95 degrees (97 when I put the thermometer on the hood), with again no system kicking in.
I'm wondering if it needs to be quite close to the Manual's stated storage range to activate? (below -4F, above 113F)
I definitely DO nearly always get the "charging limited while the battery warms" notice in winter, though the rate is only moderately lower than normal (as I recall, 7kW, while the typical rate on my charger is 9kW) for the 30-45min that the warming system is on. But again, this is thermal conditioning for charging; I'm curious about ongoing thermal management.
Other than for protective thermal management, what other purposes does leaving the car plugged in serve? Topping off the 12V battery, I suppose. Anything else?
