Maxwell Gets the Nod to Develop Ultracapacitors for Passenger Vehicles

9 March 2005

The United States Advanced Battery Consortium (USABC) (earlier post) has selected Maxwell Technologies to begin development of a compact, low-cost, high-performance, 48-volt ultracapacitor-based electrical energy storage module for use in passenger vehicles.

Ultracapacitors, like batteries, are energy storage devices. Batteries store charges chemically, whereas ultracapacitors store them electrostatically. Currently, ultracapacitors are more expensive (per energy unit) than batteries.

However, ultracapacitors provide very quick bursts of energy with more power than batteries, and they can withstand hundreds of thousands of charge/discharge cycles without degrading.

The FreedomCAR requirements for ultracapacitors, for example, specify a cycle life of 750,000 (equivalent to 150,000 miles) and a calendar life of 15 years.

That capability makes them promising devices for the capture and discharge of energy captured by regenerative braking in a hybrid.

In a hybrid electric vehicle, an ultracapacitor-battery combination could significantly improve power management and extend battery life. The ultracapacitor would relieve the battery’s load during high power times, such as initial acceleration and braking. Load-leveling these spikes would allow the batteries to last longer, saving both money and fuel.

USABC operates under the auspices of the United States Council for Automotive Research (USCAR), an umbrella organization formed by DaimlerChrysler, Ford and General Motors to strengthen the technology base of the domestic auto industry through cooperative research.

 

Maxwell is now eligible for more than $3 million in matching funds for the module development program from the U.S. Department of Energy (DOE) through the FreedomCAR initiative.

Maxwell has more than a little experience with hybrids. When ISE’s ThunderVolt gasoline-electric hybrid bus completed a 15,000 mile test conducted by the Federal Transit Administration last fall, it was using Maxwell ultracapacitors for its electrical energy storage.

This is the future of energy. The capacitors are clean technology, no need for hybrids.


The entire source energy can be housed in these and rechraged via devices that can be mechanically driven off the energy these batteries create.

To a diminished scale but easily enough to keep new charge in the capacitor on a conistent basis.

Dear Sir / Madan,
My name is George Plavsic and I am born profoundly deaf.

I am keen to be able to purchase this Tesla Motor or

Eliica.com Li-ion battery system Technology in

Australia.

Please could you send and me information of corporate

of world leaders Tesla Motor & Eliica because I am

deaf , communications brochure?.

I am not sure equipments are now selling in

Australia if so

them please give me an address.

I would appreciate to be to be involving in this

area of anything

Fuel Saving etc or Tesla Moter or Eliica Technology.

Thank you for time this letter & hope hear from you

as soon as possible.

An International Country Codes.

Thanks for your messages
