600 miles? Call me when they make one small enough to fit in a car
heyooooo
You joke but I literally pictured a super long battery for a solid bit before it clicked. I was thinking maybe it was coiled and technically really long like a spool of wire
It’s such a dumb metric for batteries. I wish people would stop using it.
Eh, it’s really not that dumb assuming there’s an average electric discharge for electric vehicles. Most laypeople don’t understand kWh beyond “bigger number better”.
I mean its a more a metric for the over vehicle. It can move its self that distance on a charge.
The battery would kWh but that alone is insufficient for evaluating the vehicle
Miles
Metric
Pick one 😂
It's what people care about.
An EV that can only travel 300 miles on a charge is a complete nonstarter for me. It's simply not enough for trips I take with regularity.
But it it’s stupid because it doesn’t really relate to anything. Different cars have different ranges with different sized batteries and different efficiencies, at different weights and different volumes, so I have no idea what it means.
Wouldn’t it be both more straightforward and more meaningful to phrase it like: x% more power for the same weight as current LfPO used in Tesla standard range
Most importantly, batteries will always be expensive, so most manufacturers will prefer fewer/smaller for a cheaper and lighter car of similar range. Aside from trucks, I don’t see why we’d ever see many 600mile range EVs, especially if we get truly fast charging
If it were any other company I would be thrilled. With Samsung, this is going to be internet enabled, you'll need an app to turn your car on and off, and it'll probably play ads at high volumes constantly while driving.
I know you jest, but Samsung is a massive battery supplier.
These will be plain old dumb batteries
I dunno man, my 21700 cells just got an OTA update and now my flashlights wont turn on without watching an ad blinked out in mores code first.
Its a battery that'll be used by other manufacturers
...then it will catch fire.
…and will probably explode.
Are solid state batteries having issues with catching fire? I thought that was liquid batteries? Or is this just like saying everything bad that ever happened with lithium ion batteries will happen with everything else?
It was just a joke, ffs.
Samsung devices & appliances are notoriously prone to catastrophic failure - as a matter of fact, I actually had a Samsung TV melt itself - which turns out is a common issue (Google “Samsung tv melting corner”).
Then there’s the Samsung battery fire issues, Samsung refrigerator safety lawsuits, etc.
So what's the catch? Is it the price?
FTA:
Apparently, they are also rather expensive to produce, since it warns that they will first go into the "super premium" EV segment of luxury electric cars that can cover more than 600 miles on a charge.
So yes. Expensive initially.
Basically, yes. The big issue with solid state batteries is figuring out how to mass produce them at a price where someone will actually buy them.
For a smaller EV It would take around 200kWh worth of battery for a 600 mile range. The current Tesla "superchargers" put out 250kWh. So whatever is going to charge this battery will have to output roughly an order of magnitude more power in order to charge the battery in 6 minutes. That's an impressive and scary amount of energy transfer.
Edit: I don't know where I got 6 minutes from. So not quite 10X the power for charging, but a LOT more than current chargers.
A couple things: solid state batteries weigh much less. Solid state batteries are 30-50% lighter per kWh. The initial ones will probably be closer to 30% lighter. A 100 kWh battery weighs about 1400 lbs (635 kg). Shaving off 400 lbs is pretty significant and results in much better range for the same battery capacity. The battery pack is likely closer to 150 kWh.
Second thing would be the charge rate. Yes, a supercharger can 250 kW output (not kWh BTW) but a few factors means that they often do not. First thing would be heat. If the charging cable or the battery gets too hot, the the rate slows down. The next thing would be the fact that current batteries have to start at a slow rate and end at a slow rate. Solid state batteries do not have those issue nearly as much and can more consistently hit that 250 kW output for a longer period of time.
This thing, they are likely using 350+ kW chargers. Higher than 350 kW is pretty rare but the odd 400 kW and 450 kW charger does exist.
And doing some more digging, I found that it is from 8% to 80% in 9 minutes. And even then, it does not say it is the same 150 kWh battery that is being charged that fast. This could be marketing crap where it is giving numbers for a ~85 kWh battery to compare it to EVs today. An Ioniq 5 takes about twice as long to go from 10-80% at 350 kW.
The current Tesla "superchargers" put out 250kWh
kW
My wall outlet charger puts out 250 kWh, if you leave it in for 2 weeks straight...
So each supercharger will need it's own miniature fusion power plant. Great, now fast charging solid state batteries will always be 30 years away.
20 years is very nice, how recyclable are they after that though?
The process for recycling solid state batteries is more complicated at the moment:
I'd love to imagine around 20 years later people would be retrofitting old and heavy phone, laptop, and EV batteries with lighter and faster-charging ones...
Finally. A true alternative to gasoline vehicles has begun to arrive. I'd never buy a current gen or older pure EV because I'd never want to spend $10,000+ on a battery replacement after its 10 years old or have something with a 250 mile range that takes 45 minutes to charge most of the way up. Give the world a 350 mile (real world usage) battery that can charge in under 15 minutes and lasts 20 years, that's total replacement territory.
Wait, are EV batteries even replaceable?
Not this one. It’s 600 miles long
I like this comment, because Samsung in other areas does indeed get confused about batteries being consumable.
