Charge Curve
Has anyone here tracked their charge curve? I've been trying to decide if my Vistiq has a thermal management issue during DCFC or if it's jus normal for the vehicle. I'm quite aware of the classic "GM dip" as I own two GM manufactured EVs, an Acura ZDX and the Vistiq. When I first purchased the ZDX it had a huge dip after around 45% or so, but some programming seemed to improve it at least a bit.
I was hoping that the Vistiq, being a bit newer, would have a similar bahavior, but the GM dip on it is far worse and more agressive. Last night I stopped to charge with about 17% remaining, and it was getting close to midnight so I didn't want to stop again before we got home as we still had 2 hours of driving, so I let the vehicle charge to 70%. I had great charging until about the 50% mark, peaking around 185kW, then slowly rolling down to about 145kW around 50%, but then it fell off a cliff, within about 30 seconnd dropping down to around 80kW before slowly starting to climb again.
This seems like a bigger "dip" than I see in most charts. I couldn't find any charts for the Vistiq but a see some for the Lyriq and they look very similar to my ZDX, but the Vistiq is worse. Anyone else charge their charging curve?
