    No problem, I've put it on my calendar so hopefully you'll post photos shortly thereafter.

    I hope you've seen this: https://insideevs.com/2019-chevy-volt-gets-7-2-kw-charger/

    My Prius Prime has a 3.3 kW charge rate and I often find myself pissed waiting at a pay-for-parking, L2 charger. Because it has air cooled batteries, most of the energy powers the AC before the battery can take a serious charge:

    Our BMW i3-REx has a 7.7 kW rate on an L2 charger and CCS for fast DC. My measurements show the cooler only takes ~2 kW.

    That is great that the Volt can charge faster, on mine it was never an issue because charged it overnight, and we had 4 vehicles, I only used the volt for EV missions, I am a contractor drive a pickup as a primary work vehicle.

    It's great that the Volt is finally getting a more powerful onboard charger, but shouldn't these posts be placed in the Volt section of the forum? Nobody is gonna look for discussion of the Volt in an Jaguar I-Pace discussion!

    Let's celebrate the improvements. David has experience with an earlier Volt and I'm sympathetic because our Prius Prime has the same limitation. The bigger issue is the question, "What should the minimum J1772 charger rate be?"

    My experience is all EVs should be at least 10 kW and better still, 20 kW (80A). I'd like to see fast_DC up to 150 kW. But then I have two plug-in hybrids which I drive daily.

    I am not a fan of PHEV's in general, I think they are totally a crutch, and their design is not optimized towards anything particular. BEV is the way to go in my opinion... I was out test driving cars again yesterday, with one of our friends, and drove Lexus, Mercedes, and BMW, the engines are the sucky part of the cars... BTW, I did have 1 great discovery yesterday, The fake leather in the Lexus NX is absolutely amazing, I have never sat in a seat more comfortable, and soft... Car makers should seek out this material, as it is the first pleather product I have been impressed with.

    That's actually what Tesla do at the moment - they parallel the Superchargers so that two adjacent unused chargepoints can feed one car at 120kW, or a pair of cars, one car at 34kW and one 102kW (or two cars at 68kW ea).

    Certainly they can parallel pairs of Superchargers so that one car could use 4 chargepoints' worth of power - but occupancy rates would have to be below 25% for it to be usable. As it is, occupancy rates need to be below 50% to achieve 120kW per car.

    The other factor, is of course, equipping the cars themselves to accept more than 120kW per car.

    Model 3s are planned to expand the fleet of Teslas faster than the Supercharger network is due to expand. So it's likely to get harder to find under-occupied Superchargers as time goes by.

    Promising but not yet the Tesla killer that people are talking about. However, I guess I should reserve my opinions till Jaguar engineers have an ability to do some tweaking of software and may be some hardware. Again, this is only one criteria, albeit an important one.

    There is a distinct difference between adapting an ICE car design and designing from scratch using EV design rules. This video shows the difference between two BMW design teams:

    There are enough videos about the I-Pace to show they were using ICE design rules and that shows.
