Same problem with our 2022 ID.4 we’re getting 46 kw now while a Ford Mustang right next to us at this EA station is getting 90+. These are 150 stations.

Same problem with our 2022 ID.4 we’re getting 46 kw now while a Ford Mustang right next to us at this EA station is getting 90+. These are 150 stations.

These always have to be given with context:

What was your initial state of charge?
What was the ambient temperature?
What was the battery temperature?
What charging rate was the ID4 asking for? (requires OBDII and CarScanner to assess)

I know people get frustrated when the charging speed isn't as expected. But the real question is why is it happening? And without the context, there's no clear explanation.

It could be as simple as that you plugged in with a high SOC and a cold battery. That instantly lowers the dynamic charge limit that the ID4 asks for. The MME could have come off the road with a hot battery and 10% SOC, making it easy for it to ask for and get 90kW.

I think this is the toughest challenge we're going to have has an EV community explaining to the general public when it comes to charging. Gas pumps generally have a static flow under most conditions. EV charging speeds depends on a constellation of factors both in the EV and the dispenser, any number which slow the charging rate. The instant example that comes to mind is the WSJ article this summer where the journalists didn't understand that 24kW DCFC really isn't appropriate for charging on a road trip.

Each charger can charge at a different rate too and often do. A more realistic test is plug in after the Ford leaves.

Took delivery of my ID.4 in May of 2021. Depsite the various bugs with the car, I have enjoyed it EXCEPT for one problem -- charging speeds at Electrify America Stations. I've been told that the 2021 ID.4 can accept charging speeds of 125kW and 135kW for the 2022 ID.4. Most EA stations have a claimed output ability of 150kW or 350kW, usually some units with each speed at most locations. I am familiar that the rate of charge can be dependent on many factors, including environment conditions, the battery level at the time of the charge, etc. I realize that the charging speed slows down when the battery gets to 80%. At most EA stations I've visited, I get charging speeds of 50 to 60Kw, even when I'm starting with a battery at 20% or so. I'm extremely lucky when I get 80Kw, and a couple of times I even reached 100Kw. For the longest time, I felt the problem was with EA and their inferior equipment. Early on EA reps would tell me it's a problem with my ID.4. I've taken my car into the dealership three times to have this issue check out and all three times I was told my car is working perfectly, as designed. During my most recent visit, I spoke with the dealership's GM, who drives an ID.4. He said the Number One complaint they hear about the ID.4 is the slow charging at EA stations. He told me they have reached out to VW, but they don't seem to listen or care. As more electric vehicles hit the roads, I have met many owner's of other electric vehicles, charging at EA stations. These include many Rivians, BMW's, Porsche's, and Fords. In all of these cases, these vehicle owners were getting charging speeds that were double or triple what I have been getting. This past Sunday in Utah, I went into an EA station iwth about 20% left on my battery and got a charging speed of 85kW tops. A few minutes later, a Porsche Taycan pulled in to charge next to me. He started with a battery level of 24% and was getting a charging speed of 195kW. At another station, a Rivian pick-up was getting a charging speed of 148kW, compared to my 64kW. This morning I called VW Customer Care to ascertain how I can get my issue escalated and have someone higher up the food chain run diagnostics or determine why I'm getting nowhere near the advertised 125kW speed ability VW has in their advertising. I was shut down. Told that since a dealer found no problem, there was NOTHING they can do to assist me. It was clear they simply don't care. Before I took delivery of my car, I received emails and phone calls from VW, with people willing to answer questions and otherwise help, since I was getting one of the early deliveries. Those people have probably been redeployed.to answer complaint calls. I'm posting this for two reasons...... 1. I'm curious what charging speeds other ID.4 owners are experiencing at EA stations (I charge primarily in Utah, Nevada and California). 2, I want prospective ID.4 owners to know that this may be an issue when you get your car, if you are depending on EA charging stations. Thanks!

I am finding the same problem with my new 2023 ID4. Charging at 65-70 kW (the same as all other ID4s at the Electrify America facility while every other brand of EV charges st least twice as fast. I can’t take this on a road trip if it takes 90 min. to fully charge. Bob

I just charged at EA, took me 25 minutes to charge from 37% to 80%. I saw a peak of 76kw but it was only 40 degrees out and the battery was adding 50 degrees.

It's a feature of the car. And quite a few folks here believe that you and I should have discovered this on our own before we bought the car rather than believing VW's claims of a 125 kW charging rate. :-(

Its only the 1st DCFC on a road trip that is slow. During DCFC the battery gets heated to the ideal 70F so that any more DCFC on the same day will be at the fastest rate and will take 30 mins.

If your State-of-Charge is below 20% upon arriving at the charger.

I see this sort of reply a lot and I'm always tempted to ask: “Why? Did I buy a car or a science project?”

I used to care a great deal about the inner workings of my cars but decades down the road, I just expect them to do what they're supposed to do without me having to faff around endlessly about it.

I've only really been on four road trips in my ID.4 since August '22, but the trend I've noticed with the DC fast charging stations is that the charging rates on my ID.4 are at best inconsistent, and at worst significantly underperforming advertised specifications.

The comment by @Atlant about a science project has resonated with me the most. To a point I've enjoyed testing the performance and limitations of the car as a system: I'll takes notes and run data through an Excel sheet, but I'm not hooking up an ODBII. Here's a screenshot of just the Electrify America charging I've done over the past 6 months along with a charge curve (manual data points) from today's charging session from 19% to 71% (note: EA shows the station delivered at max rate of 81 kW today, but the ID.4 display never showed above 77 kW).

It was 34°F outside during my charging session. I had already been driving nearly two hours so the car's battery should have been warm enough. Perhaps today's particular EA station has its own issues (a cursory look at PlugShare reviews suggests the station has been underperforming for multiple vehicle makes and models just over the past few days), but today's experience is similar to enough others I've had that the charging rate simply isn't reliable.

For daily use, and with my home Level 2 charger, the car has been great. But for a road trip, I don't have range anxiety; I have charge speed anxiety. I want a 250-mile journey in my ID.4 to not take more than 30 minutes longer than the ICE car I traded in...and between the charging speed and (in some cases) having to wait for an available charger, that has rarely been the case. I just want it to work as advertised and not have to think about it, as do most drivers.

Driving really doesn't warm up the battery very much. The only way to know with certainty is to get a dongle that lets you see the actual pack temperature and the actual dynamic limit that the car tells the charging cabinet.

But using a DCFC actually does warm the battery, so if you are on a longer trip, the 1st charge may be slower, but all subsequent charges for the day should be faster. And we are just about done with winter temperatures where we are, so faster charging should be just around the corner.
