Wondered how people are doing with the post 2.4 update charge curve?

I used a 350kW charger at Wetherby the other evening, needed a quick 30 miles or so to give me some contingency for my destination.

I was stopping a lot earlier than I normally would, and ended up plugging in at 48%.

I was a bit surprised to see the charge rate jump to 101kW, I’m pretty sure it was never that high in the 40s before, more like 70 something. I unplugged at 58% and was still pulling 81kW.

I haven’t seen any official charge curves for the 82kWh battery on the GTX, and I’m certainly not complaining, but has anybody else seen jumps in charge speed and seen a new vs old curve anywhere?

(As a Tour owner) I thought the GTX had an even better (up to 175kw at low soc) charge curve than the regular 77kw ID models?

I’ve not seen that mentioned, nor seen It at the chargers, I think it was meant to be 125kW from stock, but I did see mention on a 2.4 video somewhere that it would be higher post update?

As I do little rapid charging, I have no direct experience of this. There have been plenty of folks on the VW ID Owners Club Facebook group reporting better charging speeds post 2.4 upgrade though.

Thanks, but don’t have a Facebook account. 👍🙂

Found this Battery Life video which shows the curves with 3.0 and 3.1 software, I guess 2.4 puts us somewhere between the launch levels and these.

Seems they’ve made the curve ‘fatter’ at the front end, and higher for longer, which seems to be what I’ve experienced the other day.

Good news then, I/we can look forward to some more improvements in due course. 👍

From VW’s own 3.0 update pages - it says that 77kwh id’s with 2.3 from the factory wouldn’t be changed. But those that ota’d to 2.3 would. It should be 135kw from the start.

but iirc the GTX gets a much better charge curve than the rest 😁😢

who knows! Glad to hear it’s fast though! Summer connies certainly help!

Yes, you’re probably correct about that, mine should be 135kW as it had 2.3 from the factory.

Hadn’t noticed such high charge rates at those percentages before, hence my query.

According to YouTubers the ID4/5 GTX with 3.0 will get a peak of 175kw that drops fairly fast and matches the 2.3 charge curve at higher SoCs, and the other ID4/5 with 77kwh batteries will get a peak of around 150kw but the curve is flatter (100kw all the way to around 80% I think) and it actually does a big charge faster than the GTX. I've seen conflicting reports on which option applies to the ID3 Tour. VW state that all of the above get 135kw (upgraded from 125kw on 2.x) but that figure has been shown to be very pessimistic. Their 120kw stated limit for the 58kwh battery is also pessimistic.
Interesting that you have seen a benefit with 2.4 of plugging in at higher SoC. The VW website says that 58kwh batteries got the new charge curve with 2.4 (or 2.3 ex works) but the 77kwh only get it with 3.0. Maybe they've also done something to help it follow the ideal charge curve more closely when plugging in at high SoC, if so that would be good.

Does the GTX have 82 kWh usable? I assumed it was the same as the 77 kWh (which has 82 kWh actual I believe), but if it has 5 kWh more usable that must be nice.

Ah no, sorry, yes same 77kWh as any other ID.4 with that battery size.

I’m guessing when they launch the ‘VW Store’ though, that 5kW might be what you can pay to use for the ‘single trip range extension’ that was mentioned on one of the Battery Life YouTube videos?

That’s if they ever launch it, and we ever get it! 😂

Seems on a few ‘We run it until it stops’ type videos I’ve watched on the ID.3, there does seem to be a lot of energy to tap into even when the range is showing zero. I’ve driven to a charger or two and been on 0 miles in my old ID.3, but I still had quite a lot of blue power bar remaining, and got the feeling it would go a fair bit further. Not that I’d recommend it obviously!

At those charging rates, you should not be using the 350 charger (unless it is the only one available). Leave the 350 for cars pulling above 150;

GTX will get 175kW peak, but will slow down when battery pack heats up to over 50°C:

We stopped at Skelton Lake Ionity last night and managed a lowly 60kw at 48% charge. That's on a 58kwh ID 3 on factory 3.0 S/w.

I think a few folks were having issues though. EQA next to us was getting about 30kw until changing pump and then got 108kw.

Welcome to the forum! 😁👍

Please be assured, nobody was inconvenienced by my ‘hogging’ a charger for 6 mins and 26s at between 80-101kW, and there were 9 other 350kW chargers available and 3 x 50kW…

Worth remembering (sure you do) @Tooks that the 77kwh pack is a notably lower voltage than the 58kwh. Mines about 380-390v. Compared to 430 or more on the 58kwh. Which on an amps limited charger actually shaves off quite a bit!

eg. 50kw InstaVolts I now get 44-45.. and on the ‘150kw’ MFG chargers they’re limited to 250a - so I max out at 80ish. Pack voltage is lower with lower SOC too.

not An issue on a correctly functioning Ionity charger obvs…

I’m half minded to start a thread saying fast charger rating should be by max amps that can be delivered… which would be a much fairer(?) way… perhaps.

Nope, I hadn’t clocked that, never mind remembered it! 😂

I guess that’s down to pack configuration then?

Just to say, I’m not complaining about the speeds, mine seems to have got better since I’ve owned it, and feel sure something changed for the better with 2.4 regarding charge curves.

Yes, advertising chargers in Amps as well as kW would be a welcome change for us ‘geeks’.

No, it's not just you.

Earlier in the week, was on a BP 150kw after a short journey to it, this was at around 40% SOC starting charge and was only getting 50kw. This morning a few days later at Gridserve Norwich on one of their 350s at 42%, got 59kw down to 49kw once hit 80%. This was after a 5 mile journey from the hotel, so although it was warm outside I'm guessing the battery wasn't warm enough on both occasions as later on I stopped on the A1 at Retford services on one of the 175kw Shell Recharges on the way home (140 mile trip), turned up at 23% and pulled 110kw straight away, I stopped it at 61% SOC and it was still pulling 69kw.

This is in a Born 58kw on 3.0 software.

If this still exists in a few years time when more and more folk get EVs, it'll be all over the Daily Fail about the stories of people not getting the advertised charging rates because of the lack of understanding of how it really works and the complexities.

This is not post 2.4 upgrade but ’from factory 3.0.0` 77kWh ID.4 charge curve from my last session. I stopped the session at 65% at which point it was still pulling 120kW. I got bit over 39kWh in 18 minutes. The curve is… flat.
