Improving Battery Technology Key to Greener Cars

According to the US energy chief, Steven Chu, we need to see improvements in the car battery to facilitate the widespread adoption of electric cars. The US and Asia are racing to meet this growing need. A battery race has developed between US companies like Massachusetts-based A123 and China's BYD.

Cars that run on batteries will begin to be competitive with ones that burn petroleum fuels in about five years, the US energy secretary said at COP16, the UN climate talks in Cancun Mexico.

"It's not like it's 10 years off," Chu said at a press conference, "It's about five years and it could be sooner. Meanwhile the batteries we do have today are soon going to get better by a factor of two."

The Department of Energy (DOE), is supporting several approaches seeking to improve car batteries. The DOE's Advanced Research Projects Agency, is making investments in batteries and other technologies considered too risky for the private sector but that have big potential.

In order to make electric cars comparable to gas powered cars, Chu wants to see car batteries that last 15 years, with a five to seven times improvement in energy storage capacity and cost reductions of about a factor of three.

E-Range: World's First Fully Electric 4x4

The world's first pure electric 4x4 has completed extensive testing by Oxford-based Liberty Electric Cars. Liberty has been working on the electric E-Range project for the past two years.

Liberty says that the E-Range has a top speed of 85mph and accelerates from 0-60mph in about seven seconds, with a range of up to 200 miles on a single charge.

The E-Range is also first to market with wireless charging. Rather than use conventional leads and plugs to recharge the battery, the E-Range simply needs to park over an induction plate for one to three hours.

The E-Range's 75kw LEC battery pack is the largest ever installed in an electric car yet it employs industry leading lightweight technologies.

Liberty's patented high-density Lithium Polymer batteries are also expected to have a lifespan of 13 years or 300,000 miles, this is much longer than any EV battery currently being produced.
