Hyundai/Genesis/Kia models max out at 97/98 kw charging speeds at all Tesla Superchargers (even 325 kw chargers). If the app could consider that it would make planning much more accurate in this case.
This may not be just a Hyundai/Kia problem / limit. With some manufacturers transitioning to 800V+ architectures, a number of the legacy charging sites will result in a slower charging experience. Maybe add a ‘charge rate relative to car capacity’ to site quality feedback? Being able to get some charge is good - but being able to get rates that approach the car’s advertised max rate is better and results in a better trip experience.

Yes, but the rate will be vehicle model dependent. In the case of the IONIQ 5, it’s the power limit of using the rear motor as an inductor for the boost converter.

It’s a 400v vs 800v issue
