VOITH TURBO SELECTS MAXWELL TECHNOLOGIES' ULTRACAPACITOR MODULES FOR HYBRID TRANSIT BUS DRIVE SYSTEMS
Voith Turbo has selected Maxwell's 125-volt Boostcap ultracapacitor modules for braking energy recuperation and torque assist in low-emission, fuel-efficient, hybrid-electric transit bus drive systems. Voith and Maxwell have entered into a strategic supply agreement through which Maxwell is Voith's exclusive supplier of ultracapacitor modules assembled in the United States to meet local content requirements.
Voith has booked various hybrid system orders for the California based transit bus manufacturer Gillig which has also completed system tests at the Altoona Bus Research and Testing Facility, an American test center for new model buses and technology.
Ultracapacitors' high braking energy recuperation efficiency, long operational life and reliable performance in all climates make them an ideal energy storage solution for parallel hybrid drive transmission system Voith DIWAhybrid. It enables transit buses to improve fuel economy by as much as 35 percent compared with standard diesel buses, according to Voith.
Voith has selected the Maxwell HTM125 which is encased in a rugged, splash-proof, IP 65-compliant, aluminum chassis, weighs less than 60kg and measures 315x425x744mm. Integrated monitoring capabilities and a highly efficient cooling configuration enable it to sustain continuous current of up to 150 amps with minimal temperature increase in high-temperature environments. Its modular design makes it a versatile building block to satisfy various application requirements, and up to 12 modules may be linked in series to deliver a total of as much as 1,500 volts.
