Here's why fast charging doesn't work: I tried making my trip in the Spark. Got to Carlsbad Outlets at 9pm last night on reduced power. This is the sign that greeted me.
3 hours of 3.3kw L2 charging later - made it down to the DCFC near Qualcomm Stadium.
It's now midnight. At least I can get a charge right? NOPE. Denied.
Plug car in - error. Says car's done charging. It's not, there's 6 miles of indicated range left.
Get on the phone with NRG for 30+ mins. Reset charger, tried plugging, unplugging, everything. Can't get the car to charge.
NRG guy says they are showing that it's charging, but I'm getting nothing.
Ok, I still gotta get home. Find an L2 and plug in for a couple hours.
By the time I get home it's 2am, I've been messing around with getting a charge in the rain and I'm soaked. Only to get a royal ass-chewing from the wife for being home so late.
What should've taken a hour, maybe an hour and a half to drive ended up taking me close to 6 hours. Most of it sitting in a cold car in the rain (don't want to turn the heater on while charging on L2, I'd rather have the power go to the battery instead of heat)
Thanks NRG for the great infrastructure (not!) Thankfully I don't have the monthly subscription, what's the point of paying for something I can't use?
FWIW, I'm optimistic on the future of DCFC. It sounds great in theory, and if there were as many DCFC's as there are L2's or even CHAdemos it might be tolerable.
The reality is, at the present time, DCFC is simply not a reliable way to make a trip >80 miles.
