    "Samsung SDI unveiled on Monday a new battery cell that will charge electric vehicles faster at this year’s Detroit auto show.

    The battery maker said its new battery cell, which should be mass produced by 2021, will enable EVs to run up to 500 kilometers with just 20 minutes of charging.

    When produced, the new battery will offer the longest mileage for electric cars, the company said. Tesla’s Model S, which currently offers the longest mileage, runs up to 209 kilometers after charging for 20 minutes.

    “The fast charging will mitigate drivers’ concern of running out of power -- a key limitation of EVs,” Samsung SDI’s official said.

    "Samsung SDI also unveiled its new “integrated battery module” at the latest auto show. Battery module is a frame for a certain number of cells to protect the cells from outside shock, heat and vibration.

    The new module can secure up to 24 cells compared to the conventional module which holds 12 cells, offering more space and higher performance for EVs.

    The integrated battery module will address challenges of electric vehicles such as mileage, production efficiency and drivers’ convenience, according to Samsung SDI.

    “We will lead the next-generation battery technology for EVs to be popularized in the global market including North America,” said Chung Se-woong, head of Samsung SDI‘s mid-to-large battery business division."

    But the real question is: will they explode? :D
     
    Athlon2K15, Dethroy, AsRock and 2 others say thanks.

    Hope ya not just saying that because it's by Samsung, should be generally worried about a battery from any company of exploding.

    Only messing :) I like Samsung products and i use their batteries for my e-cig. Things like that do happen from time to time and i hope Samsung will get back on feet soon.

    Yeah i know, just that everyone makes it sound like it only happened to Samsung. To me it's just some thing to be aware of when buying new tech regardless of who made it.

    Remember the laptop ordeal

    Galaxy 8 soon :p, April i believe. Not as if i care about smart phones though.

    There is no information about charge power or current here, but Tesla sumer cadgers are 120 kW, so this should then be (120 *(500/209)) = 287 so something like 290 kW to 300 kW.
    That is insane power spikes for a local grid.

    At 400 V AC 3 phase 300 kW results in 433 A, that needs a cable with 3 240mm2 copper conductors and one 120 mm2 for the N. (that is 500 kcmil and 250 kcmil in backwards units)

    Using a fast charger usually means that the current is converter to DC before its fed to the car, 690 VDC at 300 kW is 435A.

    just the cable from the fast charger is going to be to heavy for some people.

    after the Note 7 Fiasco, I would be wary, I had my S5 for maybe 3 Months and its battery Failed with a bootloop, low and behold what is written on it is Made in china, the new one I received was made in Vietnam- no issues with it.

    Problem with this fast charging is infrastructure. You need massive power lines to the charging stations and also from the unit to the car. Yes, 20 minutes charge for 500 kilometers is something I'd consider acceptable for a vehicle. The 100-200 kilometers with 10 hour charge was just ridiculous. A trip to my neighboring country would take 1 day. Or 3 hours for a petrol car... With 20 minutes, you take a leak, buy a sandwich, maybe a coffee and the car is charged. Still slower than petrol car, but within more than acceptable time.

    I used to despise electric cars, but now I'm quite a sucker for those. Too bad they are still so expensive, even normal non sporty cars like Renault Zoe or Nissan Leaf. If I count yearly servicing, all the petrol I use, all the stuff that gets worn out and needs replacing and insurance combined for my petrol car and I still don't get to a price of a Nissan Leaf alone without the insurance or electrical bills. Leaf would be perfect for my short distance drives to work, to the city "center" etc.
    I also hope they'll integrate noise makers in order to warn pedestrians and give us ability to feed Lamborghini V12 petrol engine noise into them :D

    Unfortunately, there are no details on what the technology is. It might still be Li, but it might be something else. There are a considerable number of new battery technologies out there, but none have been commercialized. Commercialization of the best new technologies is the type of thing we need to see for BEVs to really hit their stride. If it is a new tech, the charging currents may not be that high.

    In the US, noise makers are law. :rolleyes:

    I have a couple problems with this.

    1.) This is 4 years from now. Samsung is saying they only expect to be able to double the current battery technology in the next 4 years. That seems kind of bad to me. I'd expect better than that in 4 years time.
    2.) Pushing huge charges into batteries at super charging stations is nice, but the 209 mile range on a 20 minute charge and a special station is not the big problem facing EVs right now. The issue is what kind of charge and range can you get out of a standard wall outlet. And with a standard US plug only being able to supply single phase 120v@15-20A, that isn't a lot of current. Yeah, you can get a 240v fast charger installed at your home, but even that takes several hours to get a decent charge. And that doesn't help when you are traveling and out in the middle of nowhere.

    When they can get a 200 Mile range with 20-30 minutes of charging on a standard US wall outlet, then I'll believe EV is ready for mainstream.

    To be able to charge up 500 km of range in 20 minutes the current will need to be massive.

    as a rule of thumb a electric car needs approximately 200 W per km, this ads up to 100 kW for 500 km range.
    to get that charge in 20 minutes you need 300 kWh power,
    to get 200 mile range from a 120 V 16A outlet (1920 Wh) in 30 minutes you need the car to have an average power use of ca 5 W per mile, the current crop of cars manage about 250 - 300 W per mile in real world situations.

    There are improvement potentials in todays electric cars, but getting 60 times as much range from the same technology is probably not feasible.

    As I thought about this announcement a bit more, I am skeptical that this will ever come to market. I saw a similar announcement several years ago, and unfortunately, I never heard after that that the product came to market. As I see it, estimates of "4-years" tend to mean "we don't really know when." Personally, I want this to be true as I own a hybrid and am considering a PHEV, but my experience is that when I have seen things like "it will be ready for market in 4-years," it never makes it to market.

    If they are making the batteries, then I'm not too sure I wanna sit on an atom bomb...

    I would hope they will restrict the explosions to the lab and not to the production versions - if we ever see them. :laugh:
