My 2020 Kona EV has winter mode as it is the preferred trim level. My question is, why can you turn it on and off? Will it do anything in warmer weather? It looks like it does not so, why not just leave it on and why can it be turned off?

Fyi winter mode warms the battery for better performance and charging in cold weather.

Not sure how much diff it makes in summer. But definitely should be on for winter.

Ya, my hope is it would do nothing until it senses the temperature is cold. But that is not clear. For less tech savvy people like my elderly parents who just bought a kona ev, fiddling with things like this depending on the weather is a problem...

I would say off. Even when the temperature is around freezing the vehicle is more range-efficient with winter mode turned off.

I think I figured-out this Winter Mode.

What it does: Warms the battery to enable regen braking sooner rather than later. Cold-soaked battery packs do not accept regen. The battery will eventually warm-up on it's own due to use, but it takes a while.

When to use: If daily commute or trip is more than just a couple of miles and where there will be some stop and go (traffic, lights, etc.). The idea behind winter mode is that the enabling of regen will gain-back the energy used to warm the battery, (and then some potentially) which makes for a more efficient drive.

When not to use: If going on a long trip and you'll be entering a highway at beginning of the trip. No sense using battery energy to warm the battery when you will not be using regen on the freeway to gain net positive payback. Another scenario is if you're, let's say, driving to the corner to pick-up your child from the bus stop. Regen will be negligible and you'll be heating the battery while sitting at the bus stop waiting. You'll use a large amount of energy for basically nothing.

In summary: If you don't want to switch back and forth, decide if your daily commute benefits from it. If so, turn it on. If not, turn it off. On the other hand, you can turn it off and on for each trip, depending on the the type of trip.
