Tesla EV battery in TV summer
 

Any Tesla EV owners that can share there experience on battery issues in the summer? I have a Model 3 that stays at my UpNorth house and I am thinking about getting another Model 3 to keep in TV. But we are UpNorth for much of the summer and I am concerned that leaving the car plugged in when the garage temps get over 100 might be less than ideal. While in TV for the winter, leaving the car in my garage UpNorth set at 50% per the Tesla forums has worked fine. But I'm not so sure about doing that when the garage gets super hot?

Can anyone with a Tesla comment on this? Thanks

Chargers
 

There are now chargers that can be controlled by your I phone. There are many articles that deal with the high temps in garages. Significant issues are discussed.

In my past life I was an engineer and worked at a Lithium battery company for a few years. All automotive but not Tesla. Our maximum safe storage temp was between 60 and 80 degrees Celsius or 140 to 176 Fahrenheit depending on cell chemistry. We did have different chemistry for middle eastern countries for the heat. Also there was degradation of battery life after 30 degrees C or 105 degrees F just like they do when they are cold but a lot less pronounced. Luckily they don't care about the "real feel" temperature!

Again, not Tesla but the numbers should be similar. Also I believe most electric cars have a auto-cool feature that will automatically cool the battery pack if the temps get too high.

I would call Tesla and ask them. My knowledge comes from selling expensive rechargeable equipment. Batteries are batteries. If, you read the instructions for rechargeable batteries they will tell you in some fashion best to charge in a temperature range. Surely that is more like 70 degrees than 100. Standby losses also go up dramatically in heat. Battery life. When we moved to Florida my car starter battery was 7 years old. I replaced it because surely it was on it's last legs. Car starter batteries, due to Florida heat last two or three years. A more modern car you can no longer get one more start out of it. Your car just says battery is weak and I refuse to work.

There are a lot of great things about Tesla the company. Post-purchase customer service is not one of them in my opinion. They do not answer the phone and eliminated the once useful online chat and thus you are left with searching their extensive FAQ and Forums for answers to questions unless you want to drive to one of their service centers and talk to someone in person. When they do mobile service, the techs will answer any questions as well.

I believe you can still email support, but in the past it has taken a couple of weeks to receive a reply. They were much more responsive before they became mainstream. Oh well. I still prefer them to Ford, GM, etc

Our very good friend has one Tesla in Minnesota, and one in West Palm. It was suggested by her dealer to heat garage in MN, and AC the garage in FL. Reason, better battery life. She did both, so no issues with the cars. But it is weird when they sit in the sun at Disney, and you can hear the car cooling off, while parked

Lithium batteries are used in golf carts. Might ask a few dealers how well their batteries hold up. Do not know if this would help with the Tesla question.

. I have had a lithium golf cart (Atomic brand) for almost 6 years in my hot due west facing garage (temps get close to 90 with door open around 4pm) and the batteries are as good as they were on day 1 (well maybe day 2). Haven't degraded a bit. Get the identical 65-70 range for close to 6 years. While it certainly ain't a Tesla it's lithium. Frankly I am surprised they haven't degraded after almost 20,000 miles as I was told their lifetime is about 5 years.

Anyway, I imagine they have Teslas in hot places in the middle east like Saudi Arabia so I think they can survive in The Villages. ;)
