...not to mention how China is dumping cheap solar panels on the rest of the world because they have a head start in that as well.....

they had an e-tron in springfield mo last year but I couldn't convince my sister, who almost bought a regular a3, but ended up with a loaded '17 gti

Tesla files patent for mobile battery swapping rig

TechCrunch
TechCrunch
September 15, 2017



Tesla is still exploring options to make swapping vehicle battery packs easier and faster. This patent filed in May reveals one option that would allow technicians to change out packs in less than 15 minutes.

This isn't the first of such ideas. Back in 2014 Tesla briefly played with an automated system that swapped Model S battery packs in less than 90 seconds. That idea seemed to be shelved as the Supercharger network started rolling out.

The system described in this patent could be installed in a service station or integrated into a mobile rig. A Model S or X would either drive onto ramps or a lift where technicians would then assist the machine in swapping the packs.

The patent notes that this is for Model S and Model X vehicles though it could have broader applications. Elon Musk previously said if Tesla pursued a mobile battery swapping program, it would be to support commercial vehicles -- just like the semi-truck platform Tesla is about to unveil.

Daimler eyes super-fast electric vehicle charging

Daniel Cooper

September 14, 2017

Daimler, parent company of Mercedes-Benz (and others) is pushing to get the majority of its vehicles to run on electricity. But there's still the issue of slow battery charging times that needs to be overcome if users are going to abandon gas. Which is why Daimler is throwing some of its cash towards Israeli startup StoreDot, which is working on a way to fully charge an EV in just five minutes.

The company has raised $60 million in investment, with other partners including Chelsea FC owner Roman Abramovitch and Samsung. Although it's the latter that's more interesting, since it's a company that knows a thing or two about the need for stable fast-charging batteries. StoreDot will spend the cash on developing FlashBattery, its replacement for Lithium Ion tech that will offer 300 miles of range on a single charge.

It's hoped that, in the not-too distant future, FlashBatteries will be built into production EVs at source as a modern-day replacement for existing power-storage tech. The fact that Daimler's backing the project makes that a little bit more likely, since the pair can develop automotive-friendly solutions together. Not to mention that it's just one of several outlandish ideas that Daimler has written checks to of late, including the Volocopter drone taxi.

As someone who thought that he was familiar with German car brands/manufacturers, I am ashamed that I have never heard of Borgward before seeing a news article about their comeback EV plans yesterday.

https://www.borgward.com/world-prem...ped-with-an-innovative-electric-drive-system/

https://www.borgward.com/models/isabella-concept/

It will be interesting to see if they can actually deliver on their promise of an SUV with a 500km range..... :popcorn:
The last time I saw a Borgward was in the mid 1960's, it looked sleek and very aerodynamic but the positive image was tarnished when it smoked a lot when started :facepalm:

500km range would need a serious battery capacity, maybe that's why it's going to be an SUV so it can carry the weight?

Meh. Hydrogen is not a fuel in the traditional sense because it intrinsically takes more energy to make the hydrogen than you get out of it when you burn it, even in a fuel cell. About the only thing hydrogen really has going for it as a terrestrial transportation "fuel" is that burning it theoretically doesn't produce any pollution. But making it to begin with is rather inefficient and storing it is a PITA.

That is what I love about my volt.

I get the efficiency of all electric, within the applicable range.

And I can still drive coast to coast as needed on gas.

Why range extenders will be a much better option than pure EV unless and until someone invents (and commercialises at affordable price) a battery that can be recharged in around a minute AND has a lifetime significantly greater than a few hundred charge/discharge cycles (how many times does the typical gas car driver refuel their car over its lifetime?)

Long distance will continue to be the bane of pure EV's, but once pure EV's reach the magic range of ~300 miles at an affordable price point, that will satisfy the majority of use cases outside of long distance travel, which we all agree will take a long time for pure EV's to manage successfully (although that is more on the infrastructure than the EV itself).

Unless you drive long distances (300+) every day, how often do you really make those long trips?

Under most circumstances, anyone with an EV will be driving less than 100 miles per day, and plugging in at home every night.

No one disagrees, that gas propulsion will be still be around a long time, but by more and more people utilizing EV's when and where possible, it a) reduces the use of gas, b) increases the pressure on buildout of EV infrastructure (and technology), allowing for the eventual coast to coast EV travel.

edit again:
another point to consider as a society, when traveling over 300 miles (or whatever particular range you want to choose), perhaps is time to start looking at other modes of travel, such as plane/train/bus.

it is a change in mindset.

Personally, 8-10 times a year. Over 1000 miles each way, but with an overnight stop. Still each day is 450-600 miles.

Gas? Pfffft. Diesel cars allow me to do those days without refueling at all. :D

Well, my 45 year old Beetle works out to about 1250 times - and it's still on its original tank, with full capacity available :D
