Charger capacity

Feedback

You use the charger capacity in kW for route planning and for charge time calculations. This is incorrect as it is the current (AMPS) and not the power (kW) that matters.

For example a DC charger is rated 1000V & 200A…this does add up to 200kW for a unit you list as 150kW, which is not the issue. The issue is that for a 400V car, you will only get 80kW out of this unit, almost half of what you use for calculations

    This is an ongoing problem in North America where ChargePoint CPE250/280 units are very common and deliver only a fraction of their nameplate power to most EVs (nameplate 125-160 kW, typical 70-80 kW due to 200-250 amp cable throttling). Avoiding ChargePoint entirely doesn’t avert the issue because some of the fastest chargers available are also listed by ABRP as being on the ChargePoint network.
