Faulty Battery. Yay.

[GratedWasabi]

Well. My brand new iPace, a 2019, has a faulty battery. Yikes.

I was giving the benefit of the doubt that maybe my driving was so crazy that it was drastically reducing my range.. but today I've confirmed my battery is not fully functional.

From what I can tell I'm getting between 60 and 68 KWH out of the battery. I don't know if it is a cell issue or the entire battery, but I'm certainly not getting near the 86 or 87 KWH.

I did a trip today, 100% charged and preconditioned while plugged in. Eco mode, climate off most of the way. Average speed was 50 MPH, mostly around 65 and never above 72. Only cruise control or super light throttle. Very conservative driving. 50 degrees and very light rain, minor wind.

My battery went into low mode after 130 miles and showed 7% remaining. The trip calculator shows almost exactly 40 KWH per 100 miles and the Eco data was all 4.9s and 5s and 97/98%. Yet at 130 miles the battery was nearly empty. This matches my overall experience so far, drastic battery drain with even minor city usage.

The 64 KWH number is also what WattCat shows me, which I assumed was a glitch.

So yeah, not sure why I traded in my Porsche for this.

I'll take it in on Monday and I'm sure it'll be an easy process getting everything squared away (note the sarcasm).

You are seeing much the same as I am. I've written up a test that I did and it will be delivered to the Dealer in a few hours. A copy has already gone to JLR.
Mine is showing 65.6kWh
If it is down to 64kWh then it is very close to being a warranty change item.
It is almost as if 1/3rd of the battery has not been connected up.

Good luck to you both, a serious pain in the backside but surely nothing that JLR can argue against. I am sure that you will soon be having new batteries fitted and be off on your merry way with a skip in your step

Maybe another batch of cars affected, might be worth comparing VINs?

I think you've only actually got around 56kWh useable in the battery from your consumption and mileage figures. Your range with 40kWh/100 mile consumption should be over 200 miles with a healthy battery.

This is below the 30% degradation level that should trigger the battery warranty replacement so you shouldn't have any issues with getting it sorted.

As SammyD has done, it would be worth you sending your numbers to JLR for the record as well as your dealer.

Below is my Wattcatt data for the past few days.

Nov 11th:
81% charge - 55.55 kW
100% charge would be 69.44 kW
Nov 11th
75% charge - 51.45 kW
100% charge would be 68.01 kW
Nov 12th
68% charge - 46.25 kW
100% charge would be 68.6 kW
Nov 14th
93% charge - 63.85 kW
100% charge would be 68.65 kW
Nov 14th
96% charge - 66.1 kW
100% charge would be 68.85 kW

So I have contacted my dealer to get my battery checked.
I live in Princeton, NJ and have had this car for exactly a year.

I have some serious concerns about the health of my battery.

The vehicle suffered from coolant leakage for the first 5 or 6 months. I didn't use the AC because it was cold. When I realized the AC wasn't working, I gave my vehicle for repair and Jaguar took 3 weeks for repair.

I am concerned that the battery pack may have some suffered damage during this time because of impaired thermal management.

If the data that Wattcat is showing is anywhere close to being correct, the degree of degradation my battery pack has suffered, is unacceptable.

I didn't use the AC because it was cold. When I realized the AC wasn't working, ....

In my Jaguar ICE cars, the recommendation is to run the AC (aka Climate Control) either all the time or at least once a month. If you don't run it, the seals can dry out and the refrigerant leaks away. I suppose it's the same on the i-Pace.

>I didn't use the AC because it was cold.
You definitely want to have the AC turned on because that's the most efficient way
to heat the cabin. Else the car will default to using resistive heating elements.

My car is also one year old and the WattCat battery state of health figure 94/95% has been confirmed by my dealer
