Car charge speed incorrect on a web plan
When I plan a route on the web the charge stops assume a much faster charge rate than the car can do. For example it says I would charge from 20% to 80% in 16 minutes - which would require a charge rate of 191kw. My car has a 150kw maximum and based on everything I've read 100kw average is a more reasonable assumption. (2024 Chevrolet Equinox 3LT FWD)
Same route on the phone app shows ~100kw charge rates (and an additional hour of total charge time).

Thank you for the reply and my apologies for not including more details. This plan shows the behavior:
https://abetterrouteplanner.com/?plan_uuid=1f6f380b-3dfe-4b7c-bfe5-e5bd8c1df097
The first charge (EVGo) shows charging from 24% to 80% in 15 minutes which is 56% of an 85kwh battery or 47.6 kwh. 47.6kwh in 15 minutes would require 190kw which the car cannot do.
Another charge (EA) shows similar results with 20% to 73% in 14 minutes.
Somewhat strangely the Tesla charges are more realistic with 20% to 73% in 24 minutes (112kw).
One difference is the EVGo and EA chargers are both configured with 350kw max and the Tesla is 250kw.
In any case the car has an 85kwh capacity and 150kw max charge rate but in reality the average rate is closer to 100kw due to a low nominal voltage of 288v requiring higher amperage which generates more heat and so reduces the charge rate.
If you can’t find a reasonable way to fix this behavior (for this car you would need to know the car nominal voltage and the charger max amperage) would it be possible to add another configuration setting for a maximum charge rate? Then ABRP would use the smaller of that value and the charger rate.
Thanks

Hi @Dave H,
I’ve checked the model itself and all should be in order. Feel free to add a link to a plan where this happens.
