Charge capacity versus station capacity

10-10-20

I have a Kona64 which I'm still getting used to.
So I rocked up to an Easygo charger in Lidl for its first free public charge; the station was advertised as AC 22kw on EasyGo's app, but I only got 7.1kw charging speed out of it. Likewise, a e-cars charger gave me less than the advertised station rate.
Now I understand that the station may have two charging leads, so the 22kw may need to be shared, but 0.5*22 does not equal 7.1.
Additionally, I have the charge current set to maximum in the Kona.
So what's going on? Will the advertised rates all be guaranteed once they go chargeable?

The max charge rate is determined by the car, your car has a 7.2 kW charger therefore that's the maximum rate it can charge at on a/c

Oh thanks for that, I must have overlooked it in the information-overload with this transition!

We got a few of these threads recently. It's an interesting development. Back a few years ago and people buying EVs knew exactly what they were getting. They knew a lot more about their car than the salesperson who sold it to them. It seems now, more people buy the car based on just a few parameters. Maybe zero BIK and just a range figure? At a stretch a TCO calculation?

No disrespect to the OP, just an observation. I guess it's a sign we are leaving the innovator stage and going into early adapter stage. Although the market penetration figure of the start of that stage (2.5%) is not quite there yet. With fewer than 8k EVs out of our 2 million cars, we are still only at 0.4%

^^^^^ what they said. You were using what's called SCP that is limited by AC charger fitted to your car. Currently the only cars here that can charge faster then 7kW from them are the Zoe,i3 and Tesla's as far as i'm aware.
For a fast charge you need to use CCS at a FCP that will give you 45ish kW

Kona can charge at up to 80kW. But not at one of those ancient ESB chargers

"The new model year 2020 in Europe (or "in many European markets" to be precise) will be upgraded and get the very important (in most European countries) 11 kW three-phase on-board charger instead of single-phase 7.2 kW."

Nice inverted bathtub-curve there unkel. I'd like to think that I'm in the very far-right of the innovators phase. 😋

Well according to the curve, you are still at the start of the innovator stage

I bought my own EV when market penetration was less than 0.1% back in January 2017 (2.5 years ago). It was clear to me sometime in 2015 that EVs were the future and I was considering my options.

Up to close enough before then I had been as sceptical as the most stubborn petrol head. I knew about severe limitations of EVs. I thought seriously about buying one, but as the one family car, they made no sense. Until the 2016 Ioniq was released with a real life range of 200km (I had contemplated the Nissan Leaf but it only had a real life range of not much more than 100km, which did not cut the mustard)
