Aren't these EVSEs load balanced and therefore available output may be limited depending on how busy they are?

I think it’s false advertising to say 350kw if it varies from 64kw to 200kw. There was no one near me when i did first charge.

It’s like super fast broadband which is only fast at 2am when less people use it.

Meanwhile Gridserve and Moto have the momentum and keep building at pace…

Has anyone confirmed these are super fast ?

Interestingly i called Porsche Nottingham and the person i spoke to couldn’t tell me if their chargers are available but they don’t show on the network.

I believe that the available power at each site determines the speed of charging. I have charged at Ionity Cambridge Services several times when there were six othef cars charging. And I still got over 225 kW each time, mainly depending on SoC at arrival. And I have seen 265 kW at a busy station near the Eurotunnel.

I also have had no problems, once connected to get high power at many stations in France, Germany, Italy, Denmark and Sweden.

Maybe the grid in the stations mentioned does not provide enough power??

I guess they mean 'up to' (as stated here https://ionity.eu/en/ionity/who-we-are) but as you know there are many variables which will impact a given charging session - battery temp, ambient temp, SOC, throttling, load balancing and so on. No EVSE delivers as 'advertised' in my experience so I guess they're all guilty of a little hype.

350kW will only provide up to 270kW for the Taycan (maximum possible).

This may also be useful (source Ionity):

If they’re 350 KW capable - then sure in the right circumstances (and there are a lot of ifs) then you could see the car draw it’s maximum charge - for a period.

I’m no Taycan charging expert, as I don’t have mine yet, but I can tell you from lots of years of experience running a Tesla is that the DC fast charging charge curve pretty well approximates a standard bell distribution curve. With the peak reached for a short time in the middle.

The fastest charges are always when you arrive with a battery at the optimal temperature and a SOC of less than 20%

Not quite - see my earlier post.

Taycan can draw a max of 270kW so 350kW is not a reality even for the Taycan.

Perhaps I worded that badly. Yes the chargers can deliver up to 350 kW but the car can only draw up the maximum what it’s design allows.

same as if I hook up to a v3 Tesla Supercharger - they’re 250 kW capable, but my car can only draw a theoretical maximum of 150 kW on DC. I practise the highest I’ve seen is 144

It depends whether it really is the station or the car too though.

If the battery hasn’t been conditioned the car limits the initial charge rate and even if optimised the maximum for a Taycan is 265kW and after about 50 to 60% charged the charge rate starts to tail off anyway. The fastest charging will always be at low SoC levels.
The laws of physics can’t be repealed

Wrong way to think of it.

More like a gigabit ethernet switch and seeing less at your device because your device is limited or something else upstream of the switch is limited. It’s still a gigabit ethernet switch. That’s not false advertising. But there are other factors.

The 350kW is the same. It’s just the rating on that hardware. But there are other factors such as your car and upstream capacity.

Here, the 350kW charger right around the corner splits the charge to 2x175 kW max as in master/slave when another car plugs in.
Practically, you won't go over 180-200kW per car that often anyway.
The advantage is that you don't have to wait for the other car to finish but just plug in and draw 175 initially where it'll drop anyway.
So there is an advantage in having it this way.

I’m surprised by al all this talk of slow charging speeds at Ionity. If you’ve not unticked the option to have the charging speed governed by the car in order to protect the battery, you’ll get the speed based on battery temp at the time of arrival. Typical speeds I get at Cobham, Chippenham and Hythe can be anything from 60 to 180 kW.

When charging at Cobham on Wednesday I was in a hurry so I unticked the option and got this:

Also I‘ve got plug to charge enabled in settings so haven’t had any problems with starting a charge since this option became available

FWIW here's a charge curve for the Taycan from InsideEVs:

For clarity as to how to find the charging options referred to above, go to charging on the main screen and you'll see this:

Bottom left of the screen (indicated by pointer) there's a three white dot menu. Click on this and you'll get to the following options screen:

You'll be ok to keep the 'Battery-saving fast charging' option unticked if you keep to the max 80% charge rule and mostly charge at home on a 7 kW AC.

Useful, thanks! But bear in mind that's a 2020 model and didn't have the latest software updates which I believe has improved the charge curve somewhat ?

I'm just disappointed as this network held a lot of promise - but really appears to have stalled in the UK in terms of expansion and build rate.

One new station in the UK in the last 2 years is pretty piss poor.
