The Langley Petro Canada charger finally went online today, so I gave it a try. Started my charge at 26%. The charger (CCS side) says 350 kV, but started pretty slowly. First 20kV, then ramped up pretty quickly to about 40, and slowly kept climbing after that, maxing out at 59kW. When my car reached 70% (40 min later), it abruptly dropped to 37%, and that's where I stopped it.
This was my first charge at a Petro Canada charger, so not sure if that is normal or not. I hope they were not throttling them back. But I can't complain, as it is free. Talked to a couple other guys there, and they thought it would be free for another 4 months (although not sure where they heard that).
There was also a Leaf charging on the other station (not mine), and he was there about the same time and got up to about 89%. But his charge was only 14 kV max and then dropped down to 4kV later. So his car was charging really slowly. At that speed, kind of a waste for those guys to use up a fast charger space.
So overall, experience was pretty good. The plug cord is not very long, though. Worked OK on the Kona, because we have a front port. Not sure how well it will work on side port cars. And on one of the charging stations (there are 2 of them), the parking area was pretty tight, and not much room to open the driver door (my station was OK).
