PowerGenix to Supply NiZn Batteries for E-Bikes for US

PowerGenix, manufacturer of rechargeable nickel-zinc (NiZn) batteries (earlier post), has entered into a supply agreement with PowerEagle, the leading manufacturer of electric bicycles in China. Under the agreement, PowerGenix will supply its NiZn cells for pack fabrication into the entire product line offered by Veloteq, PowerEagle’s North American sales and distribution partner, beginning in 2009.

PowerGenix’s power systems will be featured in both Veloteq’s power-on-demand models, powered exclusively by the electric motor, as well as power-assist models that require manual pedaling assisted by the electric motor. PowerGenix batteries will also be incorporated in future product developments including an electric motorcycle that complies with National Highway Traffic Safety Administration (NHTSA) standards.

The power density and reduced pack weight of the PowerGenix packs allows Veloteq to increase the power output and range of their bikes while still achieving battery pack weight savings of 60%.

By providing more power and runtime in a smaller and lighter form factor, PowerGenix’s NiZn batteries allow e-bike users to travel 40 miles on a single charge costing as little as 3 cents—five to six times less expensive compared with lead-acid batteries. In addition, charge time is cut down 75% to about 1 to 2 hours, providing enhanced mobility and longer travel ranges for e-bike commuters.

The NiZn batteries also offer greater durability, extending the power system’s useful lifespan by more than double that of lead acid batteries. Further, PowerGenix’s NiZn batteries provide a cleaner environmental alternative.

PowerGenix-powered e-bikes and the new Veloteq Vader electric motorcycle will be on display at the Veloteq booth at the 2008 International Bicycle Expo (Interbike) in Las Vegas, Nevada 24-26 September.



I have to say I like the idea of e-bikes - low cost to run, no fossil fuel needed, low noise, no local pollutants.

Very useful in hot cities where it is unpleasant to cycle a p-bike.

+ you can generally cycle them home if it all goes wrong.

The downside is that you are very exposed (to the elements and to other road users) without the health benefits of the exercise you get from cycling.

But they are easier on the planet (and the wallet) than motorbikes, and use much less road space than cars, so let's hope they take off.

I hope they improved the NiZN battery. When I worked with them on electric cars they never worked for long. It was a different application with 28 batteries in series.

Company had lawsuit against supplier from china. It was claimed they were endothermic and cooled when charging...
