Another Preconditioning Question

[thx10]

My car is garaged and temp in garage is typically above 59f. If that is the case then setting a departure time will not precondition the battery?

A follow up question would be at work. I don’t plug in and our temps are now starting to get to below 40 daily. There is no precondition of battery if NOT plugged in? is this correct?

Battery temperature not air temperature. Get a car scanner pro app and ORB2 reader to read real time values of your vehicle including pre conditioning.

Correct, sadly there is no option to precondition the battery off plug. Very disappointing.

What is the benefit of preconditioning the battery off plug?

Most of those parameters are encrypted and not accessible on the 2025

Vehicle performance will be much better. It won’t be at such a reduced power level.

If the car sits in a >59F garage, then there is no need for battery preconditioning.

Why is this disappointing? It really isn't needed. If it is really cold and you are heading for a DCFC, it might save you a few minutes, but that would be the only reason. Most of the time, you are heading to a DCFC after driving so the battery is already fairly warm.

The response was better performance / power right out of the driveway. Not sure about the trade between higher temp vs lower SOC, but seems directionally logical and thus a fair response.

Understood, you want the giddy-up
In situations where you might want to heat the battery for maximum power performance, you will have cold tires and a cold road, so I expect the few percent power you might miss wouldn't be able to be leveraged much anyway - especially from a stop.

They , not me, … anyway yeah I wonder if the change is noticeable in practice. At least from a battery perspective this seemed logical though.

You are completely incorrect. With winter tires (probably all seasons as well-depending on temps), I leverage almost all to all power. Just because it’s winter out, doesn’t mean the road is ice/slick or whatever you want to call it to meet your agenda.

When there’s only 3-4 jail bars it’s still plenty reasonable acceleration. But max jail bars… another story.

I’ve wondered about this too. At what temperature does there start to be a need for preconditioning? Or, what’s the warmest temperature that still triggers preconditioning in the MME?

It preconditions to 59 degrees. Therefore, IF you were going on a trip, and IF you needed the range, you would set a departure time. It decides what it needs to do, and when.
