15 minutes for 310 miles? Li Auto Mega

[DodgyGeezer]

it does seem as if China is steaming ahead with decent range and (probably more importantly) rapid(ish) recharging.

it's not exactly blessed with looks, but it does seem practical...

Convinced more and more, all these deadlines for ice cars are going to be extended, was in Lisbon last weekend, speaking to a tour guide who said Portugal are not buying into ev's and never will.

He was probably full of st about Portugal's glorious history too!

BEV and PHEV sales in Portugal increased a lot last year, to something like 16% BEV and 11% PHEV.

Oh well, if it was a Portugese tour guide, then it must be true!

I'm always happy to see another EV coming out. To me it looks great, but I wouldn't believe the range. Rather handily, Chinese official range divided by 2 = real world actual range.
As for the charging speed - nice!

Dream on lol. Glad you got your information from a reliable source in the upper echelons of business and government

I was chatting to my sherpa at the top of Everest last week.
He wouldn't shut up about hydrogen cars.
So much so, I'm now questioning my own views on the matter.
Not.

Excellent!
Good to start the week with a chuckle!

Fixed that for you!

15 minutes for 310 miles? Personally I am not buying that. The amount of heat that this is going to generate at that charging speed is a lot and how does it manage the whole process? Interesting and hope that this is real, but not sold quite yet.

You better believe it. Next gen batteries and chargers.

You can see with your own eyes just how fast it charges in this video, watch from 7 min mark

The 310 miles seems to be based on the range measured using the Chinese standard. In that case, the corresponding numbers for 2WD Ioniq 6 long range would be from (minimum) 307 to (maximum) 334 miles in 16 minutes. So a bit slower or faster than than Mega, using existing high speed charger infrastructure.

Just to compare wildly optimistic apples with wildly optimistic apples (instead of realistic oranges).

Sources:

https://ev-database.org/imp/car/1718/Hyundai-IONIQ... - best WLTP range: 382 miles, 70% of that (10-80% charge that takes the 16 minutes): 267.4 miles of (theoretical) WLTP range
https://www.licarco.com/news/ev-range-tests-explai... - "CLTC range figures tend to be 15 to 25 percent higher than WLTP" (didn't check this figure from many other sources, YMMV perhaps)

If that's an actual 310 miles and not 180 when you actually use it that's a great step in the right direction.

Shame it looks so terrible.

United Nations, EC, governments around the world have all pushed ahead without talking to THAT guy!? Madness!!

Wow, that's for sure impressive.

I think that's actually comparable to the average fuel stop, given that it takes a few minutes to fill and pay in addition to whatever short deviation you may have to make from your journey get to a petrol station.

But more importantly it's well within the duration you would need to stop for every 300 miles for one reason or another in any case, so it's 'quick enough' by any measure.

Ok, I will take that back. Impressive stuff. Though I am still cautious about some of the claims of EV manufacturers from a number who have made extreme claims. But hey, this is a massive step forward though. If the Chinese manufacturers can crack the design side for western buyers, it could well be the game changer that is needed.

It could be the game changer that a lot of people need to consider an EV. It's a tricky one as I've gone through the stats and numbers and the truth is that the vast majority of UK drivers could do perfectly well with any EV that has at least 200 miles winter range, and the time to 'fill it up' is mostly unimportant anyway.

BUT, it's clearly next to impossible to get people to think about what they really need, most will simply not entertain giving it any serious thought at all until there are a number of people (or more accurately, the newspaper/media they absorb) very clearly saying EV is now as convenient as Petrol, or something to that effect. I'm not blaming people for not being interested either, people are busy, there is no reason to think joe blogs should choose to take the time out to give serious consideration to something new, when they're perfectly happy with what they already have.

But I think once you get to real world range of 300+ miles anytime of the year and there is talk of 10-15 minutes to refill, that's when making casual excuses for an EV being 'impossible' will start to die off.

Those that have tow a boat the length of the UK 9 times a week for work need not respond to this post

While this involves big power numbers the technology tech and management isn't a problem

The issue in the real world is getting the power to the charger. 15min for 310miles probably needs over 300kW / 630A. 300kw chargers grow on trees, but a 630A 3phase supply is more challenging.

The issue in the real world is getting the power to the charger. 15min for 310miles probably needs over 300kW / 630A. 300kw chargers grow on trees, but a 630A 3phase supply is more challenging.

With the exception of Tesla Superchargers, you won't find a charger that can give over 500A yet either. Realistically the highest at the moment is 400kW (500A @ 800V), which if you can pull it for 15min obviously gives you 100kWh which should give a real 300 miles. Battery tech isn't quite there yet though.

Are you saying that the video is a fake?
The car displays over 500kW / 700A at the beginning of the charge.
Admittedly, that plug and cable set possibly has liquid cooling or maybe they have to let to it cool down before the next car comes along.
