Precondition at home

[1Lucid1]

Are there any benefits with battery preconditioning when charging at home (Level 2, 9-10 kW).

ChatGPT thinks so, but she does know Lucid. Plus her arguments aren’t too convincing, like her claim of more efficient. I hadn’t notice any efficiency or speed differences with home garage charging with varying ambient temperatures.

Getting the car battery to a comfortable temperature, which ChatGPT says is <80F in the summer (what would be the winter threshold?), may be an argument. But is it worth the energy and thought expenditure? I am interested in maximizing battery lifespan, without wasting energy.

I started to let the battery rest for 30-60min after coming home before charging. Is that a energy-free alternative to preconditioning?

At L2 speeds, as far as I know, there is no reason to worry about any of that. Just plug in and take the juice. The car will deal with itself if it needs to.

No need to precondition for L2.

I actually read this differently, there is a benefit to pre-conditioning or getting the battery temp up at home if its right before you leave for a long trip. You'll be more efficient with the battery if its at optimal temp vs being too cold.

For L2 charging, the rate is slow enough it won't really help.

I could see the use of preconditioning from the app if you were on a trip and needed to do a fast charge soon after you departed. Otherwise not useful
