My wife and I drove our ID.4 down to Mt. Hood this week, and drove back yesterday. We had to charge once on the way down, and stopped once again on the way back. For yesterday's charge, we had started out on the mountain at 59% SoC and ambient temperatures around 38F, and drove ~150 miles taking the scenic route around the mountain and through the Columbia Gorge to the EA chargers at Three Rivers Mall in Kelso. We plugged in at 6%, and were soon pulling 145kW! At 26% SoC we were still getting 140kW.

Many, many questions. Even with the AC running, I dont think I pulled more than 130

Hot damn, 140+ all the way up to 26%?? If this is the kind of charging curve we might be looking at with a future OTA to increase charging speed then that's really exciting.

This is about 107 kwh charging speed average over 27 mins based on the energy delivered of 48kwh

Anyone else see similar? I wonder if VW snuck a firmware upgrade in on some of the latter cars delivered. When did you get your first edition?

 

[Astros]

I received mine on March 31st (in my sig), and I did see a pop-up appear a little while back stating that an update was available. However, there was no record of any update later, and a DC charge a couple days before this one reached a maximum charging speed of 116kW. I plugged in at 21% that time, though. It is probably unrelated, but we noticed that several settings were reverted: the temperature was set back to Celsius and navigation was set back to adding charging stops automatically.

Can you check your software version and report back? Would be a simple way to see if this was a fluke or you are on a newer version than everyone else.

I charged today and also saw 143KW peak charging rate.

 

[seageo]

Interesting! I hit 130 yesterday peak. Followed the same charging profile as what InsideEVS tested.

Nice! Any ideas what software you're on?

This seems odd that a silent update would’ve been pushed. Maybe it’s something with the EA chargers allowing the ID.4 to “overclock” at them? I guess we haven’t seen anyone confirm their software version yet, though.

Having different software on different cars wouldn't really surprise me. I should see if I can find how much energy the battery cooling system and A/C draw. I wonder if they just came in piping hot and then sucked off extra energy.

Nothing special about the EA chargers. I did my recent charge at one too. It's definitely on the car side.

My car is still on the 0792 version of the software. If you long press on the square "home" button and pull up the service menu, you can see a detailed list of software versions for different components, but I don't know what any of those mean.

The AC compressor is variable speed and draws a max of 5.5kw. The coolant circulating pump and radiator fan add about 1kw, so that would not account for the 145kw rate.

This forum needs something more than a like button for you saving me the time to check that. Thanks!

Same here.

The real test - take an ID.4 that hit 145kW to a non-EA 150kW charger to see if it still hits the same rate.

That such a pain to find. I have an OBD dongle and evnotify, so if check in what the car records. I'm a little suspicious that EA may be misreporting. That seems unlikely, but there's nothing special that the EA chargers can do to "overcharge" the ID.4. they have a handshake that the car says "I can take X kw" as part of the CCS process.

 

[fiehlsport]

Yeah, this is really strange. Someone on the Taycan subreddit posted about them pulling ~170kW steady on a 150kW EA station too. In this case the car is saying it’s pulling more than the station is even rated for, a little different than what’s going on with the ID.4. Something is weird with these. Either the station is misreporting, the vehicles are over-reporting, or something else is wrong.

Maybe the EA chargers got a firmware update before the weekend?
