Where I live A/C is not necessary, but isn’t that what Thermal Battery Management is for? What do you do when the car is parked outside or at work?

For me, I'll park outside and accept the degradation. But it is all about limiting the time at temp. If my battery can charge at 80 degrees instead of 90 in the summer, it will be happier. Would it have been happier if I bought a Tesla - sure - but my pocketbook wouldn't be...

I am not crazy about Nissan's decision to not actively cool the battery but I bought it anyway. Since it seems like the colder temps the better, I just want to do what I can to keep things colder (within reason).

Our garage is fully insulated. Our strategy last year was to open up the main door in early morning and then keep it closed as much as possible during the day. This helped as long as we didn't take the LEAF out. But if you go out in 100F weather, the battery quickly comes up to that temperature, even if it had been down around 80F in the garage.

I would consider running a window A/C on those hottest of days, but I suspect that driving the LEAF in the hottest part of the day is its biggest enemy. It takes many hours for the battery to cool down unless it is driven in cool air to speed the process of cooling off.

My garage has a window. During summer I have a box fan to pull cool air in. It runs on a timer to catch lowest cost TOU 12a to 6a and lowest air temp. Air is expelled through the regular safety vent. I might reverse the flow this year and see if it works better. Window is higher than the vent.

Good luck to those that are in hot climates.

Have a 3 car garage fully insulated. Recent remodel freed a heat/ac vent. It now feeds the garage. Warm in winter, Cool in summer -Colorado can be extreme. :|

I used an old window A/C unit on a timer in my garage this Summer. It wasn't hard to keep the temp in there below 77F, despite a very Hot summer. I only ran the A/C at night, after peak demand.

My feeling is that if you have to AC your garage to protect your EV battery, you bought the wrong EV...

Didn't bother with a permit, did you? I don't think you're allowed to put your garage on your central air system as it would be a conduit for car fumes to enter the house.

I keep seeing this, but with a one-way flap on the outflow register in the garage, and no air return from the garage, that's a very unlikely scenario - especially if it's an EV in the garage.

Except that AC vents don't usually have one-way flaps, and the next owner (or your AirBnb tenant) might park a regular car in there. We'll just ignore the fact that without a return, you're depressurizing the house and making the system work harder. Anyway, I'm fairly confident it won't pass inspection.
