quite a leap really, and makes tesla's V4 chargers look like old hat already!
the pace of progress is incredible. i dnd't think we'd see these figures until closer to 2030.

Interesting if true, although very light on detail, and why not just go to ‘1200-volts’, which is the next step up electrically from the 400/800V current standards.
1MW delivered at 1000V/1000A delivering approx 85kWh in 5 mins is serious stuff and requires some very big, very hard to handle cables and connectors.
How is it being delivered to the vehicle? 2-wire DC or split across multiple wires/connectors/phases? What car sized EV battery tech is being used that can handle such a charge rate? How do 1MW EVSE’s work/get fed?
Questions, questions!

Wondering if this is based on the Chaomi standard: https://www.greencarreports.com/news/1140871_china... The GB/T standard it's aiming to replace seems to already have a specification for 1000Vs (https://en.wikipedia.org/wiki/GB/T_charging_standard#Charging_modes), Chaomi would increase the amperage quite dramatically.

Seems a tad overkill. Half that would still give a 80% charge quicker than you could go for a wee and a quick leg stretch.
Faster than necessary in the real life, but probably helps sell the cars and increases the revenue/profit potential of the charger.Makes me wonder what is the average time ICE cars use at the stations. You don't have the plug-n-fill functionality, so you need a separate steps for payment (with PIN codes and behind the scenes calls to the credit card company) and the actual fill-up (grab the hose, open the filler cap, fill your lungs with carcinogens for a minute or two, close the cap, return the hose). If you want the receipt, I think you might end up spending the same five minutes a typical charge on an 800kW charger would take.

The only difference is that I now never have to waste time filling up for the day to day shorter journeys.
I can't see how these crazy fast charging speeds make sense. Only a tiny % of people are really in that much of a hurry during a 300 mile+ journey, and those people alone are going to pay for such expensive chargers? Wouldn't it be far more useful and profitable to just install several 150kw chargers which are more than fast enough for the other 99% of EV drivers?
I would say this is an example of solving a problem that doesn't exist - but perhaps the problem it solves does exist, at least in the minds of those who don't currently drive an EV and fear for the day when they're pushed into driving one. These people won't be open minded about the tech until they're told an electric car fills up as quickly as a 'normal' car, so I suppose in a sense that problem is solved by waaaaaaay overpowered and generally impractical high speed charging tech.

I can confidently say that since switching to EV 5 years ago, I don't spend anymore time stopping on longer journeys than I did in the 430D I had before then. I still need a coffee/piss/lunch which allows enough time to charge even at today's commonplace charger speeds.

I think that the only problem it solves is to maximise throughput at busy sites, so less queuing time when the site is at capacity. But having been an EV driver for 4 years and only had to queue once then again it is solution for a minor problem.The only difference is that I now never have to waste time filling up for the day to day shorter journeys.

Would make sense for larger commercial vehicles if they ever make the switch from diesel.
they are the ones who have to stop for extended periods though. what it would do is knock the 'what about those without driveways' argument over. like for like 'fuelling' time.

It seems that in the Nordic countries the move is well on its way, probably due to low price of electricity. At under 0.10€/kWh for commercial users in Finland the "fuel" costs would seem to be about one-third of the Guinness record truck (about 20l/100km). Seems this winter, they started to gather experiences from a real edge case: https://www.sca.com/en/media/news/2024/new-electri... (heavy loads, cold, uneven terrain,...).

A truck would need batteries weighing like 8 tonnes or so (16k lbs) and so if you made a truck stop for say 30-50 trucks, that would be a draw of something in excess of 6 Megawatts, whereas the factory creating the trucks is only 2 Megawatts and average town (10k homes) is what... 4-5MW... and we would quite a few of them all over the UK, so how is the infrastructure going to be upgraded that much that we can have several of these in specific locations, its like you would need an SMR next to it to be able to cope with the draw.
Places like the US/Aus have it even worse, but I dont see larger vehicles moving over yet.

MB eActros 600 (22-ton semi-trailer - capacity limited by EU regulations) seems to have three battery packs, a total of 4,5 tons and 621kW (based on a quick search). LFP, so optimised for longevity and low(er) cost, it seems.
Heavier ones seem to be in operation, too: https://www.dbschenker.com/ch-en/insights/news-and...
I know next to nothing about UK infrastructure, but I would assume local battery buffering could make sense (like ABB does with its 600kW flash charging stations for buses that can be hooked into standard medium voltage grid connection). Power availability might be less of an issue in the Nordic countries since they seem to attract computing centres in the hundreds of MW category (cheap electricity, less of it spent cooling, heat can be used for district heating,...).
The examples so far seem to be from companies serving predictable, standard routes. I'm not sure if the stations would be open to anyone driving in with an electric truck. Although if they're covered by the same regulation that requires contactless credit card payment option...
The US might be especially difficult, but nevertheless, pilot efforts have been announced: https://www.maersk.com/news/articles/2022/03/29/ma...

Most don't need to stop to charge every five mins either. A full charge is 4-5 hours of driving in many EVsI travel a lot for work in my EV and ave motorway speeds are under 50mph, over the last 3000 miles my ave speed has been 44mph.
At 70mph my Polestar 2 Long Range Duel Motor Performance uses 30kwh per 100 miles and has a 84kw battery so nearly 3 hours.
At an ave speed of 44mph it's more like 5 hours.
Currently charge at home overnight so have a full battery in the morning, on days where I travel more than 250 miles I will stop and charge at a fast charger at the side of the road. Usually get around 54kw from a 30 min charge. At 70mph that's another 2 hours driving, at 44mph it's easily another 3 hours.
As soon as you plug in you are charging, walk in, take a pee, check phone messages, grab a coffee and walk back to the car is 30mins. I need to stop every 2.5 hours for a pee and to answer messages/emails/home/work chaos.
My fully charged EV can drive from SE London to Leeds without charging at a cost of £7 or SE London to Newton Abbot without charging at a cost of £7 or SE London to Edinburgh with 1x30min stop at a cost of £27, its 437 miles and over 8 hours to drive, you could stop for 2x15min charges or 3x10min charges or 4x7min charges depending on bladder, caffeine, hunger, boredom levels.
I don't need to stop and charge the car on my usual Leeds or Newton Abbot runs as there are free chargers at both offices or paid chargers at the hotels I stay in. I do however need a comfort break during the 4.5hour 260mile journey.
It does take a different school of thought to drive an EV but personally as someone who covers over 2,000 miles a month it's been painless.

Finland on the other hand is easier to convert, although the temp variation (+30 to -30) I wouldn't think that the batteries are liking that considering not all vehicles are stored out of the weather. I know how difficult our ICE cars are to start when its -10 to 15 without the integrated heater and being stored in the garage in central Finland, also in extreme weather I remember how quickly our batteries dissipated when up near Arctic Circle... The rail network over there is not equipped to suddenly take a load of freight cargo on rail to save the batteries.
I can see it happening at some point, but who is really going to create a few lorry parks to charge them when the cost to create such a part and get the infra ready is going to mean the ROI is ridiculous.
