Yup, you have to take the charging speed headlines of 100kw/125/350kw etc with a pinch of salt, all electric cars have a charge curve, usually start low-ish, ramp up quick to max as battery heats up, then slows dramatically as battery gets hot and can’t take the high (=hot) charge rates. Finally the load balancing at the end slows the charge to a dribble, hence the “unplug at 80%” you hear. At a rapid, 20-80% took under an hour, 80 to 100% another hour.
I regularly saw 47kw on the Soul as its max on a 50kw charger, but it and the Kona tail off dramatically after 76% to 25kw and then dropping slowly after that.
Inside EV’s has the charging curves for EV’s, they show a max of 72kw on a 100kw charger for a Kona, with the same drop off at 76% as a 50kw charger.
I’d suggest the 42kw you are seeing is the max the Gridserve units will dispense due to power supply issues on site.
In life, it's not who you know that's important, it's how your wife found out.
