One thing I've noticed when the battery is cold that it warms up quickly if I accelerate, coast and repeat for about 15 minutes (little hills in the road help too). It makes sense to me that this "surging" would do that but I wonder if it messes up the battery. I'd suppose that's unlikely seeing how "that's how it was built" so to speak.

I have seen youtubers doing that prior to DC charging. Another example of why we need a "precondition now" option.

I call that "Grandma Mode". My Grandmother would step on the gas, then come totally off, then step on the gas, then come totally off. Great case of whiplash when you went for a ride with her.

I'm getting a Leviton panel this summer and can't wait to geek out on circuit-level monitoring

My guess is, it does mess up the battery. Even without winter condition considerations some manufacturers limit number of hard acceleration to protect the battery. When you accelerate hard, sometimes you will have to decelerate hard too which heats up your batter more but hi current charging (regen) a cold battery causes Lithium plating which over time can result in thermal runaway. How much time it takes for the stuff to hit the fan is a function of your pack and your luck. I try not to push my luck too much.
