When you say that a car "charges at 150kW" or 270kW or whatever, I expect that means that will make a difference in how long you have to wait to charge when you're on a road trip. This actually is the case for the e-tron and the Taycan. They advertise 150kW and 270kW respectively, and they actually hit numbers in that ballpark for enough time for it to make a real difference in total wait time at the rapid charger.
This simply isn't the case for the I-PACE. For the state of charge range and the amount of time that it can stay at 100kW, it may as well just max out at 80kW.
I just got done watching Bjørn Nyland's video he posted today on the H280 update. At 9:36 you can see that he started charging at 2% SoC. The charge rate started at 97kW and crept up to 100kW very briefly until slamming down to 79kW when the car hit about 8% SoC. It stayed around 80kW until the video cut away. From other videos and charts, we know that the I-PACE drops to about 50kW by the time it hits 80% SoC. So the charge rate is only 100kW for the first few minutes, and for the remainder of the time -- about 48 minutes from 10% to 80% -- it's at 80kW or lower.
The only plausible reason the charge rate would instantaneously jump down 21kW is if there is something in the I-PACE software that did that, like a switch. In pseudo-code, "if(soc > 7kWh) max_rate = 80kW". It's almost as if Jaguar engineers are actually not happy with pumping 100kW into the battery pack for more than about 4 or 5 minutes, and even then they'll only allow it at under something like 8% SoC. Were the engineers told by marketing or management to get the car to accept 100kW somehow?
Why bother doing it at all?
It seems to me that the answer is, to claim a marketing advantage. By accepting 100kW at all, no matter how constrained and useless it is in practice, I-PACE Wikipedia page sports 100kW DC charging as a feature. But it only charges at those extra 20kW for a few minutes, and only if you drive your SoC very low and risk getting stranded from something like rain or a headwind! If you prefer to not get stranded from unexpected weather impacting your efficiency, then you'll almost always arrive at the rapid charger with more than 10% SoC. Which means on an actual real-world road trip, you will only ever charge at a maximum of 80kW.
In practice, your I-PACE maxes out at 80kW! The 100kW number is deceptive.
Fastned published some mystery chart with 100kW at up to 40% SoC (right above text explaining how to access the emergency release cable to actually disconnect an I-PACE from their charger -- nice). But we have at least 3 separate videos (linked above) from Bjørn that contradict that chart. I have no idea where Fastned got their numbers, but has anyone here with the H280 update gotten more then around 80kW when your SoC is higher than 10%? I'm sure we'd all love to see your video of it.
Note that Jaguar never actually claimed 100kW charging in their initial press release. What Jaguar said is that the I-PACE can charge from 0% to 80% in "around 40 minutes" on a 100kW charger. The Wikipedia page claims that the 0-80% time is "45 minutes using a 100 kW charger." From the 3 Bjørn videos I linked in this post, it looks like you can expect a 0% to 80% charge in more like 50 minutes.
Personally I'm fine with 80kW. I'm not running out and trading it for an e-tron anytime soon. What bothers me is when people get something less than what they're led to believe they'll be getting when they buy.
