Maxwell Technologies (NASDAQ: MXWL) has introduced a bigger ultracapacitor for hybrid and electric vehicles and heavy duty industrial applications.

The new 390-volt BOOSTCAP® Heavy Duty Transportation (HTM) ultracapacitor module features enhanced integration technology and up to 2.8 times greater energy storage than earlier products.

"Ultracapacitor-based solutions increase the efficiency of systems that consume electrical energy, which saves fuel or grid power, thereby reducing emissions of greenhouse gases and other pollutants associated with conventional internal combustion vehicles and energy generation," said Dr. Richard Balanson, Maxwell's president and chief executive officer.

"This rugged, high-performance, module is designed specifically to meet the demanding requirements of regenerative braking systems in hybrid and electric buses, trucks, electric rail and other heavy vehicles, as well as cranes and other heavy-duty industrial applications."

The new module meets or exceeds transportation industry requirements for watt-hours of energy storage and watts of power delivery per kilogram, and is designed to perform reliably through one million or more deep discharge cycles, or about 15 years of operational life for most vehicles or industrial systems, the company claims.

The self-cooled HTM BMOD0018-P390 is encased in a splash- and dust-proof, IP 65-compliant aluminum chassis. Each module is rated at 18 farads, and up to three modules may be linked in series to deliver a total of up to 1,170 volts, according to the company.

Ultracapacitors deliver up to 10 times the power and longevity of batteries, require no maintenance and operate reliably in extreme temperatures.

Maxwell is a leading developer and manufacturer of ultracapacitor cells and multi-cell modules for industrial electronics, transportation and telecommunications.
