I take it that this is why it takes almost no time to get to 80%, but it has been noted that QC'ing beyond that is not time effective.
That's not accurate for the 2013's. I can QC to 90% in 30mins. or less.
I don't know everything about how the DCQC is controlled. YET
The level 2 is completely controlled by the system onboard the vehicle.
I have built some custom L2 EVSE, and I can tell you, there is NO intelligence in there.
It's a glorified Light switch with the ability to abort if some criteria occur.
The L3 charging on the other hand seems to be controlled by the external charger, with the car reporting some data that the Chademo can use to make adjustments.
I doubt that the 2013 has any significant changes in the DC charging system that would affect it's operation over the 2012 design.
I have a pretty nice metering system, and can watch the car's internal data as it charges.
The only DCQC I have access to is a Blink Chademo, and it will not offer me the option to go beyond 80%.
(anybody know what that is about?)
My car can charge from 25% to what the charger thinks is 80% in 14 minutes.
The initial current is very high, but at 13 minutes it is down to 25% of what it was when I initiated the charge.
I'm not holding you to the 30 minute estimate number, but lets assume for now that it's accurate.
That would mean that it took as long to go from 25% to 80% as it would to go from 80% to 90%.
This is in keeping with that tapering as voltage increases I noted, even if the times are not set in stone.
Just a note: The Blink I have access to stops my charge at 72% (by meter) even though it thinks its 80% (showing on the Blink)
I'm interested to see if that changes when I get the update done.
