For your Model S? Did you have it plugged in to the HPWC or a 120 V outlet, and was it also charging?
Is it normal for the coolant pump to be running continuously for over 12 hours? The battery temp was 34C when it started as it was pretty hot outside.
Thanks.
To give you an idea of how much heat the battery retains, got to work (35 mile commute), ESS temp was at 27C. I park in an underground garage where its cool and away from the sun. Didn't read the temp when I got to the Roadster, but when I got home today on my 35 mile trek my ESS was @ 36C and I wasn't pushing the motor but being rather casual. Took 3 cool downs over an hour's period in Range Mode to drop the pack down to 26C. After the 26C cooldown my circulating cooling pump doesn't run after it sleeps. I also pop the rear trunk on the day's where ESS temps have risen above 32C to help the trapped heat from the ESS & PEM to be flushed out. Otherwise its an insulated heat trap under the CF skin.
I do firmly believe that heat kills CAC. My CAC was climbing in the mild 80F weather we'd be having but as soon as it jumped 90F and above my CAC stopped climbing and actually dropped.
I picked up a another metro-board electric skateboard (I also have a longboard) to throw in the back of the Roadster. That way I can drive my Roadster to a charging station when I get to work and ride my electric skateboard back while its cooling down. And skate back to get the Roadster once its dropped and added some charge. I haven't done it yet but now the hot weather is kicking in I want to care and preserve the ESS as much as I possibly can. Any heat wave I forsee I'll throw the board in the back of the Roadster. If I take a simple lunch break / commute with the Roadster from work the ESS rises even more and I bite down on my teeth just feeling the cells of the ESS are feeling like a hot lobster dinner.
I did a test today and each OVMS cool down cycle seems to drop temps by 3C. My pack started at 34C and after the first cool down it dropped to 31, then 28 after the second and 25 after the third.
My CAC has dropped from 154.5 to 153.3 after a few hot weather drives.
When you say OVMS cool down I assume you mean you charged in range no? Or is there a new setting I'm missing?
Yes, Range Mode. I've been doing it manually until I can find a provider who won't rip me off for a dataplan. Att wanted $15+ / mo. and no longer would sell just data for the go plan. The OVMS has a cooldown function in the SMS feature, that puts it into range mode and does I believe 3 initiations or so until it reaches the target temp you requested. I don't think its in the UI for the user app yet.
Awesome. I think I totally missed that. Do you know the SMS text off the top of you head. I don't remember seeing it in the user manual.
COOLDOWN - perform a cooldown charge (13A range mode, with cooling cycles) when the car is plugged in at this ACC location
NOCOOLDOWN - don't do a cooldown charge (default)

I don't think that's correct. I just got a SIM from AT&T that won't cost more than $100/yr including 200 SMS per month and all the data I'll need and then some. The $4.99 plan now only includes 200 SMS and no data, but you can add a data plan based on use just like the .10/min voice. The data is so cheap that you'll never use up your $100/yr minimum so it works out to $8.50/mo.
Honestly, they wouldn't sell me a plan. I told them that I had others who have the plan you mentioned above and they said it isn't available anymore. That was over a year ago. Was that recently Henry? I was looking for under $10 / mo and still want my data plan since I like the front end UI.
That's strange; my Roadster was awake this whole weekend, too. It finally went to sleep yesterday.On the topic: I looked at this thread because my roadster has been awake for 3 days, which by itself heats the battery. It's only gotten to about 75 degrees F in my garage but it shows the battery and PEM at 89!
How do you make the car Sleep? Theoretically it would cool down to ambient 75 degrees F.
