In trials, GE’s sodium metal halide Durathon batteries ( earlier post ) have successfully powered GE Mining’s Scoop, an underground vehicle that transports mining materials, at Coal River Energy, LLC in Alum Creek, West Virginia. Additionally, the battery contains no lead acid materials. Click to enlarge.

Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS). The five battery technologies fared much worse. PHS followed at 210.

But things changed for Cox when GM came out with a new version of the EV1 with a non-toxic nickel metal hydride (NiMH) battery with more than twice the energy of the original lead acid battery. “I had a 30 mile commute to work… and there were no charging stations there.”

Soft wood, such as spruce or pine, packs less than 10 megajoules per liter, whereas bituminous coal has 2.5 By this metric, air-dried wood contains about 3,500 Wh/L, good steam coal around 6,500, gasoline 9,600, aviation kerosene 10,300, and natural gas (methane) merely 9.7—less less than 1/1,000 the density of kerosene.

The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years. For electric vehicles with large battery packs, the biggest limiter is already in the circuit panel. Subscribe to our RSS feed and stay up to date. by RSS or sign up by email.

In this article we’ll be taking a closer look at ways to minimize charging losses that are under the control of either the manufacturer or the owner of the EV (in other words, excluding things like changing the electrical generation source from coal to nuclear or solar, as helpful as that would be).

Email ECOtality CEO: Fast Charging and Why Battery Swapping Is Doomed Jonathan Read discusses why electric vehicles and fast-charging systems, not battery-replacement systems such as the one touted by Project Better Place, are the future. Battery technologies are advancing rapidly. Electricity costs are relatively inexpensive.
