Leaf and heat

Mon Jun 10, 2019 5:54 am

A couple of heat related questions. I live in a south suburb of Houston, a very minor benefit as being closer to the coast gets maybe 2-4 degrees of relief from the heat. So questions so far are:

I have to park outside. I do get good shade from a large oak about 1/4 of the day. High temps are in the 90's for 3 months or so. How badly does that level affect the Leaf?

Humidity is usually in the 5x-6x% range? Does humidity have any effect?

Am I correct there is an app that would allow turning on the A/C a couple of minutes before going out to the car to take the edge off the heat inside? Does it work on a timer so if you don't get out there it isn't on forever and drain the battery?

Do You HAVE a Leaf at this point, or are you car tire kicking?

I would not recommend you having an EV in southern texas . Too much sun and heat.. Stay with a gas car

Higher temperature makes chemical reactions work faster, and the reactions that degrade a battery run faster at higher temperatures. Solar heating will increase this somewhat. I don't have any exact answer as to how long a 2019 LEAF battery will last in Houston, and I'd say that no one really does.

Not on the LEAF. There might be an issue with actively cooled batteries at very high dew points due to condensation causing issues including battery fires, but that's not proven.

Yes, and yes.

Most everything around here is wet during the rainy season. And the rainy season is long.

I would only consider EVs with battery thermal regulation in Houston. The LEAF would be a non-starter

At this point I'm researching. I learned about a $3500 rebate in addition to the $7500 tax credit. $11,000 made it sound very tempting. After further research I've learned the $7500 isn't automatically $7500 and would be more likely to be $5k or so, still much nicer than a poke in the nose but not as good as $7500. Combined with the heat issues it sounds like I'm not a great candidate for the Leaf. I should probably just keep driving my Accord hybrid.

You could lease a Leaf for 2 or three years. Don't buy one.

Not only is it "not proven" but WetEV just then came up with the possibility, sans evidence.

I will agree with other posters here: a non-temperature-controlled battery is not a good idea in hot climates. If the LEAF really, really floats your boat, take @LeftieBiker’s advice and lease it so battery degradation becomes the manufacturer’s problem and not yours.

Or save money and own the car as long as the warranty will replace the battery. Still is the is manufacturer’s problem and not yours.

I see your Tesla stock is recovering nicely. Almost back to $220 premarket.

I think it depends on what you plan to do with it. Other than Phoenix, I'm in a VERY hot area. 110F in July and August many days, with 114F not unusual. But I'm not worried about it because I don't fast charge, and if needed, can even trickle charge on hot nights. There is a 10 year degradation warranty. And I am only putting about 600 miles per month on it, about 20 per day. But most of all, I plan to sell it / trade it in within a couple years so degradation shouldn't really be an issue.

So I think the heat is a question also on how you plan to use it and how long you plan to keep it.

Don't get me wrong, I want it to last, and I'm trying to take good care of it. I charge it only between about 3-5am when its cool, etc, and I plan to report the numbers here. But for the cost to me - about 15.5k - it was an easy decision over a used 2015 for 10k. It hands down beats my truck for the 13mpg I was getting driving short trips around town every day.

YMMV!
