What's the point, travelling down the M1, stopped for a quick charge, as it's nice to see these new chargers... 180 kWh, champion, but only charging at 60 kWh - what's the bloody point! Shite!

Really don't get these so called fast chargers 🤔

What was the ambient temperature? Are you sure is the charger and not the car?
Your EV battery needs to be above 20C to charge quickly. Some countries and versions of EV6 have a feature called battery preconditioning which turns on a battery heater some 30 miles and 30 minutes or so if the Kia navigation system knows you’ve navigated to a DC fast charger so long as the pack temperature and state of charge meet very criteria. Please check other threads out there on this forum.

Had driven 150miles by then, so fairly sure the battery will have been warm. Where on the system does it tell you the battery temp? I don't honestly think the battery temp is the issue. Mercedes next to me only charged at 60 also, and BMW couldn't even get started. I feel the network, infrastructure, and systems have a long long way to go before we could ever consider calling them user friendly! For the time being they're shite!

Well, when you're driving, you're not pulling that much power. I reckon you're using less than what a DCFC would've input. In one of Bjorn Nyland's video, at 70km/h, he was only pulling between 18 and 25kW. At 100km/h, I wager it's not much more than 50kW. The battery won't warm up (if anything, it'll just stay lukewarm).
Climbing a mountain at 120km/h, that's when I was pulling around 168kW, still less than the max speed of that ABB charger.
So driving on the motorway, doesn't really heat up the battery - the EV6 is quite efficient. Couple that with the HVAC scavenging heat from the components to heat the cabin, at the motors and battery will remain cool. This is why we need that pre-conditioning mode.

If that's the case, what we're saying is, rapid charging is a fairytale in cold weather, not only are you going to get less miles per kWh, it's always going to take 3 times as long to recharge. The sell bar for the EV lowers...

it’s a bit hit and miss and also down to the charger. Stopped near York recently both chargers plastered with 150kwh stickers. Mine chargered at 80kwh. Guy next to me going great guns at 130kwh. We were discussing, I thought mine had been throttled. When he drove off popped mine on his charger and speed went straight up to 140 kwh

As my other comment I am sure that was what was happening in my case
Without battery pre-conditioning? Yeah.
Although Bjørn also said that charging at 46kW at 0°C battery temperature was impressive. He said a Model 3 would be in the single digits until the battery warmed up (I assume if you didn’t navigate to a supercharger and thus no battery pre-conditioning).

It's only a fairytale with MY22 built before July 2022. The later models and the 2023 have battery preconditioning which allows them, if they use the built in navigation and set a DCFC as an destination the capability of getting those faster charge speeds.
And as KiaevCan mentioned it is why we need battery preconditioning for those of us who bought too early. Otherwise anything approximating the advertise promise of 10-80% in 18mins is a fairytale. And saying over and over again I believe I can fast charge, I believe I can fast charge is living in a fairytale.

It shocking in reality, built before July 22 EV6, are the next equivalent low emissions claim. How can they sell a car under that pretence, fairytale charge speeds, actually only in the warmer seasons...
Nope very unlikely that even kept the battery at the same temperature. Not being mean, but I run an ODB II Bluetooth low energy dongle and it talks to the iphone running Car Scanner and so I've watched the battery on my Light just fall over a long drive. Doesn't matter if it's 100 degrees outside or 30. The battery temp starts falling, pretty agressive cooling going on. If the battery management system had any sense it would heat up the batter on a cold day to say 60 or 70 degrees F but for whatever reason it doesn't and you get a really slow charging power as a result.
Now you're 100% correct that the site could have been broken. These days in my experience and EA site is about 20% chance of being hosed like you describe. And particular sites that suck one day tend to always suck for weeks or months. Just how EA rolls.
We were sold BS and we bought it. Pretty f'ing simple. And Kia US and Canada just play dumb like Kia Germany didn't release the info back in October. Pretty crappy.
I love my car but it charges about as fast as my 2012 Nissan LEAF with a degraded battery at a Chademo plug when the Kia is cold. So it's hard to love that.
Anyway Durham your car is new, so go see if it has Winter Mode or what's it called, Battery Preconditioning...and then you'll know if it's a user error because you didn't navigate to the station properly or if it's because you have the versions like some of us here do that only have Winter Mode (bad) or the new fancy Battery Preconditioning (good).

I have winter mode, no preconditioning. And until now hadn't realised the need. I don't use the car navigation to set a DCFC location because it's functionality is pretty basic, I do not think I can set it to find DCFC chargers only. Is there a filter system I'm unaware of? I'm quite lazy and when away from home tend to just stop at service stations and hope they have a charger available. And as described on the tin, thought a fast charger fast charged your car...
My mistake. I was under the impression that all 2023 EV6 models had preconditioning. Or maybe I misunderstood that you just got the car but indeed it's second hand or a left over 2022. Or maybe in the UK few or no 2023 models have preconditioning. So no worries, you're just in the same (slow) boat as the rest of us. DC charging, any speed is a negotiation between charger and car, always. Sometimes the charger is the limiting factor and sometimes the car is. It's a rare day when both agree to limit at exactly the same number and I'd say it's nearly never that the speed on the sticker of the charger or the number it the charging app is exactly what the car will receive.
Regarding the kia navi filter that's definitely possible. For US cars (maybe similar to UK) you search for POI or Points of Interest and find EV stations. It'll default to nearby stations. In our menu in the left hand upper corner is a button that enables a filter option to show one or all of these categories of chargers: AC, DC below 50 or 60 KW and then DCFC above 50 or 60 kW.
I can understand your frustration and at least I have a little consolation for you. But before I answer some of your questions, one important thing first.
The charging power is always given in kW, the amount in kWh.
I.e. you charge a 180 kW charger with e.g. 60kW over a certain time (that's why the hour is added) an amount of energy, e.g. with 60kW in one hour 60kWh.
Because I'm from Germany, I can't answer the navigation tips in detail because I may have a different software version or equipment.
Nevertheless, you can select the charging stations under POI and click on the filter when selecting the charging stations, e.g. along the route. In the filter you can differentiate between charging station operators such as IONITY and also between charging speeds such as HPC, DC and AC.
It is best to select everything for both points, because only what you get in the filter later displayed as a charging station will be recognized by the system as a charging station and used for preconditioning if you then have the function. Otherwise, if you simply select the address of the charging station or send it to the car via the Kia Connect app, the vehicle will not recognize that it is a charging station and will not precondition.
But now to your consolation:
Your car can also preheat the battery if it has the battery preheat function. It should have, because you mentioned winter mode.
Your car warms up the battery by about 5 degrees Celsius within 15 minutes if you precondition it via the app.
For example, if you want to charge faster than 130kW on a corresponding fast charger, you need 15 degrees in the coldest cell.
From 10 degrees you get about 70+kW under 5 degrees 50kW.
So it makes sense that before you drive your car to charge, you warm up the battery to 15 degrees and run the pre-air conditioning for 3 x 15 minutes.
Important to know, as others have said, the ride does not heat up the battery. Even if, as is possible in Germany, you drive the entire battery flat at full throttle and 190 km/h. The car manages this with so little power that the airflow cools the battery faster than the heat from the engine can heat it up.
That's why it makes sense in winter to drive shorter distances between charging stops so that the battery doesn't cool down too much. You should be able to keep the temperature above 10 degrees, but there really isn't much more possible.
I hope the information helps you and I keep my fingers crossed that you will soon receive the software update for the battery preconditioning for fast charging. This is because charging works really well in winter, iff you also meet all of the conditions mentioned and the known ones too.
P.S. Another addition, because you said yourself that you don't deal much with the vehicle. I would try to fast charge the car at 20% or less in the winter. Not at 47% as you did. Then it has enough time to bring the battery up to temperature before the charging power drops due to the high filling level (SOC). Luckily, the charging curve for the EV6 is really good up to 54% and only drops sharply from 77.5% SOC.

I feel Kia should have simply put an additional button in the cab, one to push when you know your about 15-20 mins from the desired charging fast station. The car would precondition in readiness. Keep it simple I say. Especially for the important stuff.
