Further to the CHAdeMO to CCS2 ratio discussion above.
Took our leaf for a day trip today.
Trip required a charging stop on the way out and on the way back, with the fairly new Z walkworth chargers being the obvious pick:
Configuration is 2x 180kW chargers, each with two (simultaneous use, power share) cords.
Left most one is a 200A CHAdeMO cord (100kW @ 500V), and the other three are 400A CCS 2 cords. (400A is important on CCS2 cords otherwise ~350V cars like tesla will bottleneck on the cord at around 75kW, and won't be able to max out the charger).
But on ratio: Both times I turned up and every cord was vacant except the CHAdeMO one I needed. It was occupied by a leaf at the first stop and a env200 at my second stop. Pretty frustrating to have to sit and wait while the three other cords are vacant.
While only 1/3rd of NZ's EV fleet is CHAdeMO, they were sure over-represented at this charger today. A long range EV wouldn't have needed to charge at all for the trip I did today, but my leaf required two stops. Assume this location at ~65km from central Auckland will have a disproportionate representation of shorter range EV's (many of which have CHAdeMO plugs).
