Re: 100kW charging: It’s a joke

Hello,

I don't know if the I-Pace has this feature, but other cars (Tesla, EQC) have this feature.
If you set the navigation to a HP charger, the battery is conditioned for maximum charging power at arrival.
So there might be a difference, when you just drive to a HPC with using the Jaguar navigation.

Has someone tried this?

No the I-pace currently doesn't have this feature - it should have but so far Jaguar IT folks have been napping.
The navigation recognizes charging stations, it allows you to save charging stations and use those but that information is not being used to pre-heat the batteries prior to a charging stop.

I tested this out for one of my videos, just in case it had been implemented without us being told during one of the software updates. But the battery temperatures did not change at all when using the satnav to route to a charger. Definitely not a feature of the I-Pace.

Sounds like a rare case of a computer not thinking it knows better than you! :)

I got a little deeper into the battery technology of the I-Pace... Jaguar uses the LG Chem NFC Pouch Cell ... 432 of them to be correct. Useable capacity is 83,7kw, gross capacity >90kw.
If you check the battery technology of other EVs, you find some funny similarities:

there is a Audi etron 55, using 432 LG Chem Pouch Cells, useable capacity 83,7kw (on newer models a bit more)... harging with 150kw per h using a glycol based cooling system in a cooling layer , same as the I-Pace

Oh, and there is a Porsche Taycan, using 432 LG Chem Pouch Cells, having 83,7kw useable capacity... charging up to 255kw per h... only difference here, it is cabled for 800 Volts

So, there is no technical Reason in reducing charging speed and I think no contract with LG limiting it.
Jaguar is babying the battery solely for warranty issues to avoid costs

what I have seen the last 2 days on my 1400km roadtrip in the I-Pace is the strange behavior of the BMS and the battery cooling.
I will report this more detailed later on 😁

I would perhaps suggest that maybe the agreement JLR is able to reach with LG Chem over warranty is no where near what Audi, Porsche (which of course means that it was actually the the mighty VW group) can achieve because of sheer buying power. The bigger you are the more weight you can throw around and make demands that a small/er business just wouldn't be able to make.

I have been pretty vocal on this forum and to Jaguar that I am VERY disappointed in the I-pace DC charging capabilities and that there is an approx 35% gap between promised/advertised DC charging speed (0-80% in 40 minutes) and real world actual performance (5-85% in 54 minutes).

However today I made 4 Ionity charging stops and 2 stops showed above real world average performance although still not the advertised speed.

Stop 1 I charged 38,567 watt in 29 minutes to 71% SoC which gives avg speed of 79.8kW/hour
Stop 2 I charged 49,184 watt in 40 minutes to 84% SoC which gives avg speed of 73.8kW/hour
Stop 3 I charged 56,260 watt in 41 minutes to 77% SoC which gives avg speed of 82.3kW/hour
Stop 4 I charged 68,520 watt in 65 minutes to 100% SoC which gives avg speed of 63.3kW/hour

During the 3rd stop when walking back to the car after dinner I was surprised to see the charging still going at 82kW at 70% SoC - it had charged 50,015 watt in 36 minutes => 83.4kW/hour.

Despite stop 4 (after I dropped family at hotel) having the slowest average speed it was by far the most impressive - the avg speed was only so slow because I charged till 100%. At 65% SoC I still charged at 103kW/hour - having charged 39,618 watt in 24 minutes => 99kW/hour. At 70% it still charged at 94kW - at 75% the speed has considerably dropped but still 68kW - by that time I had charged 48,712 watt from 20% to 75% in just 30 minutes =>97.4kW hour.

This was earlier this week:

If my math is correct, that’s 78.7 kW/hour over a 43 minute time, up to 82%

That last one is actually hugely impressive. That would come really close to the advertised 0-80 time. Shame that I consider it hugely impressive that it came “really close”. That should be normal! But I’ve learned to temper my expectations sadly, and that last one is actually a good session. If only they were all like that.
