In the 4 months since we’ve had the Kona I don’t think the charging speed has ever maxed out. And definitely in the last 2 months it has never exceeded 42-43 kWh. This has been at various SOC, with and without another EV sharing the charge point, warm weather, cold weather, and nearly always at GridServe 120kw chargers (I just don’t drive near other vendors, unfortunately)

I did try an Ionity charger once just to see, but the charger was duff.

Does anyone else get close to the claimed 100kWh max charge rate? And if so how do I determine why ours won’t get anywhere near that without having to visit the dealer?

max charge rate for kona is around 50/55kwh irrellevant of how big the charger is.  so about 55mins 0 to 80%

It’s 77kw max dc not 100. 11kw ac.

Charging from 20% to 70% mines charges around 70kwh never had the full 77kwh.

i stand corrected. i knew it was well short of the 100. i read that most dont stay at peak charge long, and drop back.

biggest public charger around here is 50kwh anyways. and there are precious few.

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.
