One Step Closer to Game-Changing Electric Vehicle Batteries

[wtmusic]

"Envia Systems’ breakthrough battery is one step closer to commercialization after a public vote of confidence last week from the CEO of General Motors (GM), Dan Akerson. ITIF has previously blogged about the battery, which performed at an energy density of 378-418 watt-hours per kilogram (Wh/kg) in independent tests. In contrast, conventional electric vehicle batteries possess substantially lower densities – the battery of the high-end Tesla roadster, for example, has an energy density of 121 Wh/kg, while the Nissan Leaf’s is 79 Wh/kg. GM is conducting further tests on the battery, but its CEO expressed hope that it could be installed in an electric vehicle in just two to four years. 'These little companies come out of nowhere, and they surprise you,' Akerson remarked in regard to Envia. 'I think we’ve got better than a 50-50 chance to develop a car that will go to 200 miles on a charge. That would be a game changer.'"

I'm a skeptic when the company's name could be the name of a drug for erectile dysfunction.

1. Two years is just about perfect.

The lease on my current electric car expires around then.

...and I agree with the 200 miles on a charge number. My experience is showing that seems to be the sweet spot.

4. in Australia

Petrol stations are supposed to be no more than 300kms apart so as to lessen the possibilities of people running out of fuel. So, from our point of view the magic number is about 300km i.e. about 200 miles!

--> so, yeh, I agree this sounds like the sweet spot industry should be aiming for as a selling point!!

2. Seems like it should be higher than 200

The Tesla Model S already goes to 300 miles per charge (with the highest end battery option)...

3. The battery is lighter than Tesla's

This means a battery with the same weight as Tesla's would give 600 miles.

A battery the size of the one used in a Leaf would go to at least 200.

5. !!!which they will of course!!!

This means a battery with the same weight as Tesla's would give 600 miles.
Mate, if that's fair dinkum then the world will change on a dime!!

Lol, and if the asians start making this stuff us westerners are cactus!!
