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.LDB415 wrote: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?
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.LDB415 wrote:Humidity is usually in the 5x-6x% range? Does humidity have any effect?
Yes, and yes.LDB415 wrote: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?
Not only is it "not proven" but WetEV just then came up with the possibility, sans evidence.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.
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.SalisburySam wrote: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.
I see your Tesla stock is recovering nicely. Almost back to $220 premarket.SageBrush wrote:I would only consider EVs with battery thermal regulation in Houston. The LEAF would be a non-starter
