I had to do a long journey today. Stopped at the Rugby Moto services where Gridserve have 350kW CCS chargers. Yet my Enyaq only charged at (max) 42kW, despite it having the 100kW option on it. A VW ID.3 near mine was charging at 72kW (the chargers all display the rate).

 

I was only down to 50% battery when charging, but I did expect it to go fast until 80% or so and then maybe slow down. Has anyone actually done a fast charge on the Enyaq? It did slow down to 30kW or so as it went past 80%. I stopped it at 87% as I knew that would be enough for the day.

 

Also, other than the dealer saying it was on the car (I bought it from stock), is there any way I can check the option is actually installed? I'll be giving them a call anyway on Monday...

You will only get max charge rate at low states of charge, typically below 15%. At 50% it won't go at full chat and will ramp down slowly to 80% full and then drop off significantly. So for long trips its fastest to drive down yo low state of charge then rapid charge to 80%. See the graph of charging rate below. 

 

 

Hmmm - not what the dealer said. Was told it charged at 100kW to about 80% then slowed down. Plus on that graph, I should have been seeing approx. 70kW charge if I was at 50% battery, dropping below 50kW once reaching 80%. I got no more than 42kW, dropping to 30kW by the time I stopped at 87% charge. Incidentally I have only done one other fast charge from about 20% on a 50kW charger and only got 42kW max on that too. I put that one down to the charger, but now I'm not so sure.

Gridserve state all their chargers are powered by 100% pure sunshine. Presumably they close down at night.

Well, as a sceptic, I suspect plenty of BS is at play in their marketing blurb. I also suspect that hubs where there are a number of high power 350kW chargers, need to intelligently share what energy Gridserve may have access to at any given moment in time.

 

Every power utility and his dog seems claims they sell 100% green power. But plainly, that is simply not possible.

 

 

 

 

Obviously many need to be using the other electricity produced from wind farms & solar, and where the solar & wind is being generated have storage in the form of batteries which many have.  The ASA will be down on Gridserve if their advertising is a lie.

No 100 or 100 + kW chargers here.    '30% electricity generated from solar'.

Gridserve & other Commercial businesses are doing it differently from other Charging Hubs like Stirling & Public Low Carbon Charging Hubs..

I think you need to run the battery down low, then try it on a rapid charger. At least then you’ll know it actually has got the 100kw charger. What you’ve  seen on the fast charger seems to suggest it isn’t working properly or hasn’t got the capability. 
I’m personally not convinced the 100kw thing makes a lot of difference. The fact they can only take a really fast charge when the battery percent is low is one of the reasons I wasn’t bothered about upgrading from the standard 50kw charger. Fortunately I don’t regularly go beyond what I can charge at home with and it seems the 100kw option just saves 20 minutes or so. 

Obviously a 100 / 100 + kW charger makes a difference to many when charging compared to a 50kW charger when a car can charge with 100 kW charger.

 

My car gets charged on 50kW chargers and charges pretty quick mostly to 80% but that can be hit or miss at different chargers,

and then it is less quick from then, and pretty slow from 95% plus.

(Charged on 50kW or 22 kW chargers because that is all that is available, i would pay to charge quicker sometimes if chargers were available where i am at when charging is required.)

 

It is a damn sight quicker to 80% when on a 100kW charger.   This makes a big difference when on a journey and sitting about waiting to get going.

20 or 30 minutes is a big difference if like me charging is needed at least every 150 miles and you are going 300 miles plus.

 

Currently with only 50kW chargers available i allow an extra hour for every 150 miles driven as getting on a charger is not guaranteed, and then time can be wasted messing about driving on to find an alternative charger.

Then before continuing if away from home you might be with the vehicle still charging yet again.

 

At least when the weather is very cold outside you can be dead toasty in the vehicle while charging and hopefully keep the windows from steaming up.

Wind Deflectors so windows can be down in snow or rain are rather important if a driver or driver and passengers are going to be sitting in a car for maybe an hour or more charging.

yes I have done 100 kW on an Ionity charger at Perth.

You only get the highest rates if you start the charge at a low state , around 10%, same as every EV. Sakdy the dealer who told you otherwise doesn't know what they are talking about .
