It won't make that much of a diff. At most it will reach ambient temps outside (unless your garage is greenhouse with lots of windows, or the garage door faces south), so mid 90's in the day, mid 80s at night. Humidify is non factor with a sealed battery.Like most Floridians, my garage is not air conditioned and gets very hot in the summer. Is this an issue for my Rivian’s batteries? My understanding is that excessive heat can shorten battery life. Appreciate any advice.
Upper 90’s in the garage is not at all unusual in the summer.It won't make that much of a diff. At most it will reach ambient temps outside (unless your garage is greenhouse with lots of windows, or the garage door faces south), so mid 90's in the day, mid 80s at night.

Based on that article, I’m concerned. It’s 84 in my garage right now and it’s just March. Friend just suggested insulating the garage doors as a first step and see if that keeps it out of the danger zone.Found this 2013 article...
Protecting the Battery pack of your EV in Hot Weather - PluginIndia Electric Vehicles
"Lithium-Ion Batteries And Heat
Lithium-Ion chemistry is extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would. Battery performance begins to suffer as soon as the temperature climbs above 35°C. A temperature above 35°C affects the battery pack performance instantly and even permanently if it lasts many months."
>35C = >95F
Cutting it pretty close with mid-90's. Then again, it sure beats really cold temps.
What is the outside temp right now?Based on that article, I’m concerned. It’s 84 in my garage right now and it’s just March. Friend just suggested insulating the garage doors as a first step and see if that keeps it out of the danger zone.
So your garage is one degree over. Not bad. Your worst case scenario is 95 in august.83 in Tampa.
There has never been an officially record temp of 100 in Tampa but we’ve come close. Not so sure I’m out of the woods. I’ve definitely seen the temp in my garage in the upper 90s.So your garage is one degree over. Not bad. Your worst case scenario is 95 in august.
Exactly. Rivian seems to throttle charging when battery gems are 50 to 55C. That’s 120 to 130F. Don’t worry about a 95F garage.This isn’t an issue at all. The cells get much hotter when charging and I find it unlikely that the internal battery cell temps would exceed air temps. Even so, everything is controlled by the vehicle so cooling could run if they got too hot.
