A persistent with making electric attractive to the general public has how to build one with sufficient to be marketable without using heavy and expensive batteries. New technologies and electric refuelling offer some hope of around this problem.

acid batteries — the type for years to power the starter, and accessories in gas-powered cars — are too heavy to be suitable for electric designed for long-distance travel, Michael Bergeron, vice-president of at Zenn Motor Co. a Toronto of low-speed electric cars for use.

The ZENN electric car seats two and is roughly the size of a Mini-Cooper. ZENN Motor Company))

uses lead-acid batteries in its Low Vehicle, which is available in where it may be driven on roads speed limits of 50 kilometres per or less (so far no other Canadian has approved its sale), and through 25 retailers in several U.S. but Bergeron says lead-acid needed to support highway and distances would weigh too

That’s why Zenn has a 3.8 per cent in EEStor Inc. a secretive Park, Tex. company to develop battery alternatives ultracapacitors. Traditional capacitors can small amounts of energy — one of uses is maintaining power in devices while batteries are but not enough to compete with Ultracapacitors store much energy, and can be recharged more than batteries before out.

Zenn hopes to use ultracapacitors EEStor in a future product the CityZenn that would a 400-kilometre range and a 125-kilometre-per-hour top

But while EEStor says it has some progress, prompting recently to announce plans to its stake in the company to between 6.2 and per cent, it doesn’t have a product yet, and no public tests have verified its about its technology.

Lithium ion

An alternative technology attention today is the lithium ion a technology increasingly common in and computers.

Tesla Motors of San Carlos, Calif. chose ion for its Roadster, a $109,000 electric car that can run about 400 kilometres on a and has a top speed of a sizzling 200 kilometres per

Lithium ion technology has the best of density and cycle time, Michael van der Sande, Tesla’s vice-president of sales, service and This means it delivers the power for its weight and is reasonably to charge.
