We’ve had our 2020 ipace for a couple months now, and have our first road trip coming up soon.

Having never dc fast charged before, I thought it would be a good idea to drive to my local Electrify America and make sure the dc fast charging sockets are all working etc.

Well - everything worked, but for the 5.5 minutes I spent there, the charging speed stayed below 19kw. This was a 350kw charger at my local Target with about 6 stations, all 6 of which were in use (not sure if that’s a factor). The total cost for this charging session was 43 cents (1.505kw in 5min 20sec), which probably gives you an idea of just how little charging actually happened.

anyway - my question is … what can I realistically expect on a road trip? I know the ipace doesn’t charge as fast as some of the newer offerings, but please tell me I can expect better than 20kw when road tripping?

and do people generally have better experiences with EA, EVGo, chargepoint, etc?

thanks all for the help

What was your initial mileage available, when you started the charge? The 100kwh charging capabilty is usually only available with a car that has a low charge. I have had good luck with Chargepoint 60kw chargers. Bad luck with EVGo chargers. It probably depends on the station specifics more than the brand.

I was around 46% SoC believe l. I’d understand not getting the full 100, but I sincerely hope I can expect a lot better than 19, otherwise this road trip will be a nightmare.

Up to 102kW for a period of time if SOC is low. Tapers down to about 80kW from about 35-80% SOC. Tapers down from there. All of those figures are for a warm battery (about 65-80F). Rates will vary outside the sweet spot.

If the battery is cold, some energy will go to heating it. If the battery is hot (summer months) some energy will go to cooling it. You can expect low battery charging rates until temperatures are acceptable for a higher rate.

I suspect the battery was cold in your test.

that makes sense thank you! Yes today was about 39 degrees F. But - I had been driving the car for about 45 minutes before starting the charge. Wouldn’t that have warmed the battery some?

and are the charging speeds you described (100 kw below 35% and 80kw from 35-80%) theoretical or realistic to expect in real life?

thanks!

It has been my experience on road trips. I don't expect 100kW rate in winter months. The battery never gets warmed to the sweet spot temperatures.

I don't want to be a negative-nellie here, but what you have experienced is not unusual. I have been relegated by many EA chargers (both 150kw and 350kw) to incredibly slow speeds of charge. 19 kw is not out of the question. Do keep in mind that some chargers (like some of the EA ones in Wisconsin) can cost you by the minute....not by the kwh. Therefore, if you are getting 19kw at a per minute charger, EA will slam you for big bucks. I got stuck at one where I needed the juice just to move a little down the road (bad planning by me) and it cost my a pretty penny just to get enough power to move to a cheaper charger. I took a picture of the screen on the charger where it showed that it cost me $1.57 for 1.53 kwh. Yikes. Use the Plugshare App to help pinpoint good chargers for your I-Pace. It requires a little research but its worth being prepared.

I've found that switching chargers often helps. I did a Montreal-Toronto trip a couple of weeks ago and was getting 35kW on one machine and up to 100kW on the one next to it. This happened twice so there is something that makes some of these chargers twitchy. These were not EA chargers, but I've had that happen on EA as well.

EA is having some hiccups. Many have reported poor charging experiences with them on other forums.

Your experiences is similar to mine, and I actually freaked out at first but then was reassured by this forum as well!

You shouldn’t expect such low numbers once the battery gets warmed up.

This is super cold and a far-from-low charge. Yeah, you got an expected charge rate. Get it down to 10% and you'll do better. In 39F weather, your battery is going to never really get up to temp unless its driven straight from a heated garage, in which case it should be at 100% already.

In the last couple of months I've driven up to Syracuse NY in sub freezing temps a few times. I always stop in Binghamton at one of the EA sites there. Routinely I see peak charging rates of 70-90kW when starting from 10-15%.
The battery will warm while driving normally at highway speed, albeit not to optimal temps.

thanks for the info! 90kw from 10% SoC is great. Like I said, this was my first dc fast charging experience - sounds like it may have been charger issue and not an ipace issue.

What charging rates do you typically see as SoC increases?

I have always had disappointing fast charging experiences, from EA to Tesla to others, in three different EVs.

you are correct, 19kw is extremely low, EA has been problematic for awhile now, many chargers, especially the 350s are not delivering anything close to high speeds.
next time try an adjacent unit.

Same here, 25kW peak charge speed with a SOC around 50%. Other users told me I should ask for a battery software update (this update can't be done thru OTA), which solves this issue, but I haven't done it yet.

Interesting. Does anyone know what the latest software version available is? My car shows TCU 20.2 and battery energy control system br-aaj-be-ae-be

I don't typically sit and watch the charging, but rather work, check emails etc. The rate does drop after 80% rather badly. I know on my Syracuse trips, I'll need about 80% to get home, so I charge to around 90% for comfort/peace of mind etc. See recent session before the holidays. That was almost exactly 60mins.
