No, not crazy. Something seems very wrong.

Did you get a battery health report before buying? I would head to the nearest JLR dealer and request one.

What warranty did you get? Remainder of initial 8yr? Sounds like a bad battery and you're going to need that warranty.

 

This is very useful information about the battery health check. Thanks for this tiny useful information many of us don't even bother with such things. But it helps us remain aware before taking any action.

 

No, I didn’t get a battery report but will ask the dealer for one.

I have the balance of the original factory warranty, thankfully!

 

I agree with Qtown. This sounds very much like a bad battery.

 

Sound a bit like my battery. The car is at the dealer and has been for some time. Parts are hard to get. Starting to see more reports like this. Not something JLR wants to talk about. Way too soon for these batteries to be failing.
I wonder what discussions JLR has had with LG.

 

a 2019 FE with 5200 miles.

Does it have all the latest software updates applied for all the modules, especially the BMS?

 

I think it's behind updates.

WattCat says:
TCU Software Version J8A2-70712-AS (14.2)
TCU Config Version J7A3-70713-BS

Inside the car it says:
Vehicle connectivity system: 15.2

Hello and congratulations!
1. Charging issue - not sure here, mine will shutoff every now and then for scheduled time charging and have heard of others doing so as well.

2. Power fluctuations and battery temperature will effect this.

3. Your Kat will evaluate and rate range based on 500 mile judgements. Not sure of your driving style. This can be reset for fresh start; bjorn has a brief YouTube on this.

APP - would recommend the WATTCAT app if you have not already done so. Not sure about the OB2

Additionally, I would add that all vehicles are prone to weird electrical gremlins, ICE vehicles as well. Some of these can and do fix themselves. Others you can email from your jaguar app for engineers to take a look at. Have had success with this route in past. I currently have one in for wipers popping up about an inch when you turn vehicle off for example.
Cheers

 

Thank you. There's definitely something wrong and I am scheduled for service Friday morning.

I fully charged (stopped at 94% with GOM 264 miles) and drove my daily commute the past two days. According to MyPace, I consumed 11.7kWh driving 35 miles. SOC went from 94% to 50% (should be more like 80%.) My average consumption was 33.8kWh/100miles. I've intentionally driven in Eco mode with full regenerative braking. At this rate, I'll get 70 miles out of a fully charged battery pack.

What I've discovered is that the actual charging time seems accurate to refill what I consumed driving, but that the car is estimating time based on what it thinks it should take to go from current SOC to 100% at its full battery capacity.

It really sounds like you have a battery issue. I think this goes beyond the hobby-level explorations that we all enjoy here and needs to be attended to by a Jaguar service centre. Either the battery has some bas cells or something really off in the way the battery is manage because you should be able to charge to 100% and anything else points too an issue.

 

The software in the I-Pace should be smart enough to inform the driver when charging time is way off.
But the software (GOM) is not smart. If you depend on it, you could run out of juice in the middle of nowhere.
When mine went bad, I did not get a warning lite until the battery was totally dead. And that was after the car
had been sitting in the garage and not driven on the road for a while. My theory is the battery charges to the least common denominator, the bad module, and won't let the other modules charge either.

 

You don’t need to reset the trip. There is a trip auto that automatically resets every time you start the car. Granted it does not show the whole data since last charge of you have multiple stops.

 

Car has been in the shop since last Friday morning. Finally heard today that it just needed some updates and to be fully charged on level 2 because level 1 generates too much heat to get to 100%. WattCat and MyPace now show the battery fully charged with an estimated 35.55kWh capacity. (42% optimized in WattCat although I know this number may be arbitrary. )

I watched them charge it on their (7kW) level 2 yesterday. Went from 38% to 100% in about 2 hours. Impossible if it were really filling up ~50kWh capacity of the battery.

I asked for the battery health report and I don’t think they generated one. The service advisor has to check with the technician and call me back. Grrrrrrr.

 

Yeah that battery is toast. Bummer.

 

Here's the state of health info. Apparently it's just fine?

 

Wow, multiple cells down in the low 70s. Technically they can say "the battery is >= 70%", but that battery is not healthy

 

I was told when I got mine by the jag tech that variance from cell pack to cell pack was the bad output of a state of health report, not nessexarily what the absolute value was. You want those to be plus minus 1% of each other.
I think the state of health report is overhyped generally having gone through it once but that one does not look good at all. You’ve got 22% variance between the highest and lowest reading packs.

 

20% of the cells are less than 80%. Overall average is 84.9%.
This does not explain a 100% state of charge = 35.55kWh which is 39.5% of 90kWh capacity.
What is being used to charge the battery?
Can you post screen shot of WattCat or MyPace at 100% SOC?

 

Thanks for posting that printout. It proves that JLR's battery SOH is meaningless for all practical purposes. You have less than half of battery capacity. Your battery pack is bad. There's no doubt about it.

Next steps: 1. Charge to full. Drive until almost empty, recording all trips and sum up the total miles. 2. Record %age battery SoC. 3. Charge to full and record how many kWh went in.

 

Thanks all. I will pick it up tomorrow and do as suggested.

I don’t have screenshots at 100% but the figures I posted above were directly from the apps at 100%. Here’s where it’s at now.

 

Do you have to pick it up? That readout says the car is showing 30kwh of charge at 86% of a 90kwh battery pack.
that’s not right. They have not solved the problem.

 

Maddening, I know. They don’t seem to have any interest in further troubleshooting so I’ll have to do more data collection myself and make another appointment or call JLR.

What state are you in smatchley? (I mean geography not psychology ) Apologies if you've already told us ... I ask because of lemon laws. Though I don't know if they apply to second owners. There may be a lawyer in your future if the dealership doesn't just take the car back.

 

haha, I’m in Arizona. No lemon law for used vehicles here. I purchased the vehicle online from Vroom. I’ll get some more data together and call JLR if need be and see where they take this. The battery will only get worse over time.

 

Is there no recourse with Vroom?

 

If there is no recourse w/ Vroom, and you only have the remainder of the original warranty, you need to start abusing that battery like there is no tomorrow to make it degrade faster so they’ll replace it. Launch from the line every time you can, use L3 chargers whenever you’re in the area, and when you have to slow down, do it as suddenly as you can so it gets max regen.

 

Yes! I totally agree. Run it down to zero a few times, that will kill it dead.

 

Vroom touts a great buying experience. I suspect you’re outside of the 7 days but maybe you can get their attention.
I’d also consider going to a different dealer.

 

I haven’t called Vroom, but I am past their 7 day return period and don’t think they have any obligation to help given the factory warranty.

 

We're rooting for you here! So sorry you have to deal with this in what should be an awesome experience.

 

Haha you guys are funny and great.
The nearest alternative service center is 100 miles away. It would require stopping twice to fast charge just to get there. That alone might do it!
