rengerative breaking does not work until the battery charge goes below ~93%. that may be another reason to not fully charge and maybe keep it at ~92%. if the software allowed a charge limit, I would have tried it.

My car allows regen when the battery falls to 98%, within the first mile of driving. I get that folks who regularly go down a hill after charging might like to regen right away.

Regarding charge limits - the developer of an open Kia/Hyundai API and I recently experimented with charge limit queries, and were unsuccessful. All we found is Kia (via the API) does appear to talk to the car when a properly-formatted charge limit command is given. Yesterday I opened a ticket with Kia CS to try and find out what should and shouldn't work.

The Kia Access app also allows one to try and set a charge limit for the PHEV... that fails with the same error I saw when directly querying the API. It's either a mistake; modifying the charge limit is not really an option, or it should work and the current Access implementation just has a bug. The vehicle info query response includes an AC charge limit of 100%, exactly like the EV reports AC and DC. For the PHEV I'm starting to suspect it's really a read-only object, given it's not settable on the dashboard either. (In the EV, both AC and DC limits are settable.)

Even if it starts working it's not something I'm likely to use, and am pursuing it mostly as an exercise to explore and learn the API. The potential for automation is impressive - though you have to watch out for excessive 12V battery drain from frequent car queries.

I'm not seeing a setting to try and set a charge limit for the PHEV (2023 SX) in the Kia Access app. Where is that? Or is this something you're experimenting with via API and is not a stock feature?

See below. I click the Edit Charge button. Set AC say to 90%, click Save. The one clue it's not fully baked is the DC charge level (N/A) also appears settable. It sits for about 30 sec, then returns the message "Invalid Status Response."
Via the API I then experimented with the same method that sets charge level - AC at legit numbers like 90 and other values for DC like 0 and -1 or omitting the DC attribute altogether. Some immediately returned "improper format" and others did the same as above.

Thanks for sharing!

Interesting. Your app looks much different. I've only had the car and been using the app for just a few weeks, and I'm on iOS. The "charging settings" is an entire page dedicated to a whole lot of nothing (notification settings only).

Am I still not looking in the right spot?

Thanks, dblackfl, for looking into this. I have a 2023 Niro EX PHEV I would use that feature as I do live on a hill. I hate seeing the "regenerative braking not available" message every morning. If I could charge to 90% I would, and get a few free miles when I leave the house. Please let me know if you get an answer from Kia on how to implement this feature or API.

when your battery is at 98% and you press the paddles for regen breaking, do you not get a warning? I get it: Google Photos

Sorry, I need to correct myself. Just took the car out for a short drive after a full charge. It allowed regen shortly after SOC fell to 97%, about one mile down the 35 mph road and while still showing 26 miles estimated range.

Out of curiosity, what year and model Niro do you have?

Sounds like the max battery SOC threshold for regen was lowered for the 2023 PHEV.
