I don't know, but the voltage choice is a bizarre boundary case. A car needing over 500 V is probably way over 500 V - like 720 V nominal - so even the fully discharged voltage is probably over 500 V and no charging can occur at all.Does anyone know how 500V DC charging stations behave if a car plugs in and requests, say 550V terminal voltage?
Will the station charge the car to a maximum of 500V, or will it not charge at all?
Are you considering a pack around 500 V nominal, so a 500 V max charging station could take the pack from fully discharged to roughly half-charged, if it interprets a 550 V request that way?
