With the random spikes?At some point we'll re-do the test at that EVGo station, however the charge curve was oddly similar at one of the rare 350kW ChargePoint stations and a brand new EA station.
I'd definitely watch the dashboard I mentioned next time you do a deep fast charge. It clears up a lot of the questions.
The truck will definitely thermally derate at the moment, but so far I've had the fast charger derate off 500A first on new and old EA installations. Unfortunately i havent driven out to an EA Signet station to try yet. Basically, when the truck says it's the chargers fault it's not lying.
They need to improve preconditioning and increase the max temp before the truck derates at the moment. Precondtioning is often not successful, and their thermal limit for the battery is a fair amount lower than others while also kicking the cooling system on at the absolute last minute typically.
