Accounting for 800v cars at 400v chargers
I can find any documentation about it, but it seems pretty clear to me that the routing algorithm does not consider the massive time penalty of charging an 800v car at a 400v charger. For a given model, the maximum 400v power is a known figure. In my first long trip with my Lucid Air + NACS converter, I've noticed it's was way too keen to send me to a Tesla Supercharger, even if there's a 800v option across the street. I realize there's an option for preferred providers that I could use to deprioritize Tesla, but that's not a good option. Newest generation Tesla charger actually do support 800v, and maybe some 800v chargers are so unreliable or low power that I'd rather take the 400v penalty. I need an app to figure this out for me!

Downscale 400V charge rates for 800V vehicles.
Feature request: option to downscale 400V charger rates for 800V vehicles.
For vehicles with an 800V architecture, please provide an option to downscale 400V charger reported charging rates, to their realistic charging rate cap (e.g. 100 kWh). I.e. Tesla superchargers (400V) have a 300kw charge rates, but on an 800V car, this is effectively only 100kw, therefore I am better off being routed to a true 150kw charger, not the "300"kw 400V charger. As this affects the Tesla Supercharger network, which is Australia's most extensive charging network, this has a HUGE impact on total route times, when charge rates are actually only 1/3 of what is advertised.

On the flip side, Rivian Adventure chargers are 1000v/300kw, and the app says they will charge much slower than other 350-400kw chargers with my Kia EV9, but they easily pull the maximum ~240kw.

Out in the Rocky Mountains we are constantly planning and relying upon Tesla Supercharger 400V stations. Our EV9 is slow on these chargers and the time is not accurate in the routing.
