I will get excited once this leaves the lab and is actually on the market.
Oh, wait…
There’s a reason you can’t import BYD to the US.
Is that true? I didn’t know that! Here in my country BYD seems to be selling really well. I see them all the time while driving.
Yes. It’s been a long standing thing that imported cars have been married or otherwise taxed to some extent so that American cars can be competitive.
Yeah that’s the reason
You mean Mr. Orange Toilet unclogger?
Because Tesla bribed some 100% tariffs?
Faaaar from just Tesla.
Ya ya Time will tell
What the fuck does 5 minute charge mean? Zero to full in 5 minutes? For that big of a battery I believe that is not physically possible
All EV batteries aren’t “a battery that size”. They’re a bunch of small batteries all strung together. The “battery that size” statement you made is pretty much meaningless.
It’s very much physically possible to charge a battery pack at mostly empty to mostly full in 5 minutes. The tech and chemical side of actually getting it done hasn’t quite officially happened yet. Battery charge\discharge rates are measured in “C”. One C is an hour for a 0 to 100% charge. So six C would be 0 to 100 in 10 minutes. That’s doable right now. You’d need 12 C for a 0 to 100% charge in 5 minutes. That has happened yet, but it’s getting pretty close. 11 C can be done to go from 0 to 80%.
Likely, BYD’s charging statement is based for the regular layman such as yourself and refers to something along the lines of a charge from 10% up to 80%.
As a side note, it’s also annoying having these “new EV battery has x amount of range” is dumb. You could get that range 20 years ago if you made the battery pack a lot bigger. What you need to know is the energy density and the size. Like 400 WH per kilogram is currently a really good capacity. Double what you could get from like five years ago.
Which part of physics prevents that exactly?
The main problem is having a charger with enough power to fill the battery that fast. But it’s more of an infrastructure problem.
Also the numbers given are usually for a 80% charge. I don’t know if it’s the case here, but probably.
Assuming electrochemical, thermal inefficiencies?
This is one of those rare situations where reading the fucking
manualarticle helps:A standard home charger trickles power overnight at roughly 7 kilowatts, like a garden hose. A Tesla Supercharger—long considered the gold standard of public fast-charging—maxes out around 250 kilowatts. BYD is unleashing six times that amount of energy, effectively hooking the car up to a high-pressure municipal water main.
During a live demonstration onstage, BYD plugged in its new Han L sedan, making the battery jump from 10% to 80% capacity in exactly six minutes and 30 seconds.
The amperage to do that is insane, either you’re dumping power from town sized feeder lines (seriously limiting where you can place those chargers) or you are charging capacitors to charge the car (wasting energy and limiting how often you can charge a car at those speeds)
They use battery banks, so the system can charge slowly without overloading the grid and charge the car quickly. But the user will pay more for charging that fast. I’d expect to have much more slower chargers and few of the fast chargers. Most supermarkets these days have a charger, so if you’re not in a rush you can just shop and charge.
Wasting energy how exactly? Idk how efficient capacitors are in general.
What comes down to 430 miles, or about 6 hours of highway driving. It’s made for the crowd that does a road trip a few times a year and really wants to drive non stop. Or those living in an apartment just want to charge once in two weeks.
Another question: is how many charge / discharge cycles are possible?
Usually the faster you charge a cell, the fewer times you can do so.
That would be great. I’ll believe it when I see it.
The current v1 blade battery has operated in the real world about the same as their original announcement, which also was viewed with skepticism.
These aren’t research laboratory battery advancements without real world scenarios attached. These are announcements for an improved product entering production. Like a new phone being announced, not just a white paper from a lab that hasn’t been scaled.
Also, the brand that made this product spec announcement is the biggest electric automaker in the world, by far. To stay with your comparison, it would be like if Samsung would declare that their new phone will have 100W charging and 6000mAh capacity, while the actual phones sold by them could only be charged by 50W and have 4000mAh. It is just unimaginable that they would be lying about sth that can and will be easily verified the moment the first products reach the customers or reviewers.
I’ll be very impressed. I’ll even buy one if the claims are true
Are you in the US? Because if you are, they’ll never let you buy or import one.
I’m so glad I’m not.
Sure.
Sounds similar to the battery donut labs claims to have made.
No the battery is LFP, fairly conventional. The new thing is the super powerful charger and the cooling system.
The cooling system needs as much energy as what’s been put in the battery XD
