Kyle Didn't Believe BYD's Flash Charging Claims So he Went To China To Verify

[Tooney]

2 starting points:
Backstory - starts at 3 min - 6 min long
Charging test begins - starts at 42 min - 10 min long

Hopefully the germans have the "same tech" in the works for the the next gen Taycan/Macan/Cayenne - they are gonna have hard time not keeping up with these speeds since BYD have plans for thousands of these to be deployed in Europe.

Why china? There's already a handfull of spots in europe, and 3000 more in the next 12 months.

BYD is throwing money at europe right now.

One thing these guys are not showing is that the denza car will charge at a flat "curve" on a ionity/GoFast station, maintaining 350/400kw 0-90% - so it absolutely has the advantage at any fast charger by the simple fact that at any speed below 1000, it's preatty much flat max speed of the charger, not a curve.

Funny you say that, because BMW said it's impossible and surely those cars batteries won't resist more than a handful of charges - and once the first stations made it to europe, BMW's engineers walked back the claim, saying they could do it too, but they believe 400kw is plenty fast

400kwh (or 3 to 4C) is not fast anymore , the main issue these days is to deploy 1Mw+ dispenser you need a good grid connection and BYD solved it with buffer batteries

10C should be the standard! and the funny things is that "Tesla the energy company" is stuck at 2C for a decade with most cars at 400v

10C should be the standard!

It will be, in europe. IF they can actually deploy 3000 units in 12 months, and then flood the market with cars that support it, it will become the standard.
3000 stations at 2 plugs per station, that's 6000 plugs - as much as Ionity has today.

But these are big IFs - for now BYD is stuck in controversy in their factories in europe, since the chinese workers they brought from china to build the factories are being abused according to european work standards - no actual workers have complained, as they do get extra pay and work culture is different after all.

Meanwhile, Porsche promised 2 Porsche Charging locations by end of year, maybe. They're still confused about this whole EV thing

EDIT: to add, BYD installed since january 5000 unit in China, with 2500 already in use.

Not yet there. 10C LFP batteries are still heavy and suck in cold climates but improving.

it is there, the demo of the 10C is with -30C temps

So a CATL demo last week equates to should already be a standard amongst current production?

I had to look up the meaning of 10C. For others who may not know here it is:

Wonder if there will be any long term battery degradation when charging at this speed.

If 10c becomes the norm, I wouldn't mind a car with a smaller battery if it was cheaper and lighter.

.

The cars are already on roads; there are already stations installed in Europe; and there are thousands of these stations already installed in china.

It’s not exactly “since last week”

That’s the plan; they will put these batteries in all of their cars, including cheap ones.

You still get 8-12 years of warranty, which cover excess degradation also

I think the European/ US world now really needs to wake up in terms of EVs.

For so long, almost everyone has lambasted China about fake, inferior, copied products and almost always discredited technological innovations (and a few of those assessments were probably deserved and likely true, but in the past).

Innovation and development in the South East countries is now happening at such a pace, that it is almost comical. Not just EVs, roads, bridges, railways, hospitals - the sheer speed of ‘getting things done’ in those countries is incredible.
I think the West is now losing the race… And while a lot of us may not like it, but doesn’t mean it ain’t happening.

While the BYD charge very fast, they have bad efficiency, the cars are super heavy and the suspension isn't great.

So for now it's a one trick pony.

If you take a lot of long trips and need to DC charge, then that one trick is a pretty compelling argument even with the other shortcomings.
