eGMP on 400V, time planning is incorrect

With the update for Hyundai and Kia now being allowed access to the Supercharger network in the US, I've noticed an error in the time accounting when ABRP plans a trip using Tesla chargers. eGMP cars like the Ioniq 5/6 and EV6/EV9 have a charge speed limit of about 97kW (for 2021-2024 cars, for 2025s it's going up slightly to I think 125kW) on 400V chargers like all existing Superchargers are. In the route planning ABRP does, it seems like it's expecting that I'll be able to charge at the full 250kW that a given Supercharger is capable of (or at least the 237kW that my car is capable of), and is therefore accounting for the time that way, but that's not correct.

Can we get an update to account for that? I know you can set a charge rate for a particular charger in its details, but ideally the route planner would be aware of whether a charger is 400V (SC up to v3.5) or 800V (v4, which barely exists in the wild so far) and will take the 97kW limit into its calculation, and maybe detour around slower 400V chargers in favor of an 800V charger that might be slightly out of the way, but will overall take less time. Most importantly, having ABRP be aware of 400V/800V will output the correct charge times for us.

“Where does this happen” choices selected because I have iOS and web, but I assume the same thing would happen in all ABRP interfaces.

    My plans in ABRP appear to be taking this limit into account now. This is for my Kia EV6. The charge times shown imply a cap around 98kW

    This is important for acccurate time estimates
