EV charging at 11Kw on a 22kw charger!??

[Jazz12]

Appreciate inputs from fellow EV mumsnetters please!!

We have a new EV car (yay!). We charged it at a 100kw rapid charger a cppl of days ago and the max that went in was at 40kw.

This afternoon, I charged it at a 22kw public charger. It charged at 11Kw max.

what’s going on!?? Does this mean my home 7kw charger will charge my car at 3kw!!?? That’ll take forever!!

Do your EVs charge at 22KW at a 22KW charger?

Is it one of these solar panelled public chargers?

No, just normal public chargers.

Was someone else on it. Some of the annoying public ones say 22 then if there is two cars from same charger they do them both at 11. It’s not all of them, just some where they have basically one charged and two leads not two chargers and two leads

Lots of variables to consider, e.g. were you charging from flat or just topping off?

I am no expert by mine charges at different speeds depending on the car, battery, the charger, the weather and how full the battery already is.

I have a Hyundai Kona 64kW and I find on a 150kW charger, it goes 55kw at first, when it gets to 20% it slows down to 45 or so, and then at 80% it slows right down to 20 or less.

I had a DS3 before and that was slower to start but didn't taper as much.

I feel like it charges slower in winter or when you haven't warmed the battery up much. But that might be me freezing my tits off at the charging station (I don't have off-street parking so go to a public charger).

I basically charge from 15% to 100% once a week overnight on a slow charger which takes 8 hours at 7kW, or I go on a Sunday morning with the paper and a coffee and charge to 80% in 40 mins, or 100% in 1h10 mins! So usually I just go to 80% as no point staying longer.

There were no other cars charging at the same time.

Also i charge when it gets to 20%.

Some of them will only charge at 11kw unless you are using a supercharger ( using a plug with the two big prongs as well as the round plug ).

Check the settings on the car - you can change the power it charges at.
also, the “fuller” the charge is, the lower the charge will be regardless of how powerful it “could” be at max - so if the car has hardly any range at all and is on a 100w charger it will take a high rate of charge and as it gets more and more charged, the power coming into the car will drop despite you not changing anything.

Our Smart ForTwo will charge at 22kW, our Jaguar iPace will not. It depends on the car. What model do you have?

Mine will only charge over 11kw if the plug looks like the one on the left - if the dc circuits are being used.

If it was a 22kwh AC charger then not all cars can charge at that speed using AC, lots can only charge at 11kwh or 7kwh despite being able to charge faster using a DC charger - the ones with the extra 2 pins at the bottom.

Your car's battery is DC, not AC. Charging on AC requires the power to be converted to DC and so it's slower, and some converters cannot handle higher voltages.
