Samsung’s new EV battery gives 372 Miles of range and a 20 min charge 80% range of 310 miles.

These articles are so silly. 372 miles of range in what vehicle? A Suburban? A Smart4Two? A Zero Motorcycle? Batteries in and of themselves do not provide miles of range. Miles of range is not a unit of measurement for a battery.

Oh well...it's a marketing thing I suppose.

Samsung says it hopes to get the battery into mass production by 2021.

I'm every hopeful for new energy storage improvements, but every time I hear "in 5-10 years" my enthusiasm drops precipitously.

The skeptical part of my brain also gets hung up on the numbers.

For example let's assume as starting point that we're taking a vehicle with about the same EV efficiency as the Volt (say 4 miles per kWh), that would mean the proposed battery would probably hold roughly 93.5 kWh of energy for motion. I'm not even sure how to calculate the rate you'd need to push that much power in 20 minutes...but I do know the numbers would be FAR in excess of any current home electrical system.

If it charges a 100 KWh battery in 20 minutes to 80 KWh, that is an average rate of 80 kwh/0.33 hours = 240 KW. My guess is this will have to use one of those 350 KW charger coming out this year.

I hope they're not using the same chemistry and density that the Galaxy Note 7 used that caused all those spontaneous combustions.

well, at least you wouldn't have to worry about keeping warm on a winter drive right?

(make a man a fire and you keep him warm for a night...set a man on fire and you keep him warm for the rest of his life)

No one would ever ever ever ever ever install such fast charging systems at home. It would be akin to Tesla's superchargers... placed along highways and in other public places with industrial/commercial power sources to facilitate long distance driving when quick recharges are necessary. Not in people's homes.

The vast majority of charging would still be done overnight at home at rates easily handled by residential electrical systems, just like charging our Volts.

Or we'd have "accumulative" charging stations at home like a souped up version of the power wall, where it charged up slowly over whatever period of time, then super-fast charged the vehicle from that unit, not the grid.

Sure, kind of a trickle charge to fill the charge station. Maybe a Tesla powerwall unit with a fast DC output for car charging? Seems expensive.

The Note phones appear to be an issue with how little expansion room they left for the battery pack and not a problem with the batteries themselves, assuming rumors are correct. Report comes out this month.

I.e., I trust Samsung batteries just fine.

From the Engadget areible

Instead of fitting cars with more battery cells, which in turn adds weight, Samsung hopes that by delivering smartphone-like fast charging, consumers won't suffer from range anxiety and will be able to drive longer distances without lengthy top-ups.

That wasn't the only announcement Samsung SDI made today at the North American International Auto Show (NAIAS) 2017. The company also confirmed an improved "21700" cylindrical battery, a large shotgun shell-shaped cell with "improved energy density, power and performance."

Using words like "smartphone-like fast charging" and "shotgun shell-shaped" has me thinking this will battery definitely explode in a fiery blaze.

If the "shotgun shell-shaped" cells don't all go off at the same time you might get a nice Gatling gun effect!

Samsung, the company that brought you exploding phones that were banned on commercial flights.

The original article was from Jan 2017. It's now four years later, no revolutionary Samsung battery in an EV to be found. I've learned to just ignore all the news about the next cool battery that is poised to revolutionize the EV industry. I think the next revolution isn't a battery at all, but Mr. Fusion. I can do without a flux capacitor.

But then you'll be missing out on time travel

Just avoiding the unintended consequences of messing with the space time continuum… the temptation to undo the recent events is just too great.
