Maxwell Technologies Introduces 125-Volt Boostcap(R) Ultracapacitor Module

The new module is to be implemented into heavy hybrid and electric vehicles.

Versatile Building Block Eases Integration for Systems Requiring up to 1,500 Volts


SAN DIEGO, Calif. - Maxwell Technologies, Inc. (Nasdaq: MXWL) has introduced a compact, fully integrated, 125-volt BOOSTCAP® ultracapacitor module to provide an easy-to-integrate building block for scalable energy storage and power delivery solutions for heavy hybrid and electric vehicles and heavy duty industrial applications requiring up to 1,500 volts.

Dr. Richard Balanson, Maxwell's president and chief executive officer, said that the new HTM BMOD0063-P125 module is based on 2.7-volt BOOSTCAP MC3000 Power cells and incorporates proprietary balancing, monitoring and thermal management capabilities to ensure industry-leading charge/discharge performance, high reliability and long operational life.

"This high-performance module is designed specifically to satisfy rapidly growing global demand for ultracapacitor-based braking energy recuperation and torque assist systems for hybrid bus and truck drive trains and electric rail vehicles," Balanson said. "It 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 charge/discharge cycles, which equates to more than 15 years of operational life."

Michael Everett, Maxwell's vice president and chief technical officer, said that integrated monitoring capabilities and a highly efficient cooling configuration enable the new module to sustain continuous current of up to 150 amps with minimal temperature increase in high-temperature environments.

"In addition to managing high current, this module is built to withstand the harsh environments and extremely demanding duty cycles that are typical with heavy transportation applications," Everett said. "Proprietary design refinements and material science also are significantly reducing manufacturing cost, positioning Maxwell to compete favorably with other energy storage alternatives."

The HTM BMOD0063-125 is encased in a rugged, splash-proof, IP 65-compliant, aluminum chassis, weighs less than 50kg and measures 315x425x744mm. The complete data sheet is available at Maxwell's website http://www.maxwell.com/ultracapacitors/products/index.asp. Up to 12 modules may be linked in series to deliver a total of us much as 1,500 volts. Maxwell also offers a complete line of standard 15- to 48-volt multi-cell pack and modules, and recently announced a "Quick-Turn" program that offers shipment within 14 days of receipt of a customer purchase order for custom-configured modules for applications requiring up to 540 volts.

BOOSTCAP ultracapacitors deliver up to 10 times the power and longevity of batteries, require no maintenance and operate reliably in extreme temperatures. In transportation applications, they efficiently recapture energy from braking for reuse in hybrid and all-electric drive trains, reducing energy consumption and emissions. They also provide compact, lightweight, "life-of-the vehicle" solutions to stabilize automotive power networks and power new, all-electric subsystems, such as drive-by-wire steering. In mission critical industrial applications, where backup power is critical for continued operation or a soft shutdown in the event of power interruptions, they provide reliable, cost-effective, maintenance-free energy storage. In wind turbine blade pitch and braking systems and other industrial applications, they provide a simple, solid state, highly reliable, solution to buffer short-term mismatches between the power available and the power required
