Maxwell Technologies Inc. reported that it has delivered BOOSTCAP® ultracapacitor cells and multi-cell modules for more than 1,000 hybrid transit bus drive systems through the first three quarters of 2010, and sees continuing strong demand going forward. David Schramm, Maxwell's president and chief executive officer, said that approximately 2,400 BOOSTCAP-equipped, low-emission, hybrid transit buses already are in daily revenue service worldwide, and that, based on current consumption rates and customer forecasts, that number could reach 3,000 by year-end. Ultracapacitor-based energy storage systems are highly efficient in absorbing recuperative braking energy and delivering stored energy to zero-emission electric motors for acceleration in electric and hybrid internal combustion/electric vehicles. Ultracapacitors operate normally at temperatures as low as -40 C, and are designed to perform reliably through one million or more deep discharge cycles, or about 10 years of operational life for most vehicles. In April 2009, Maxwell announced purchase orders valued at approximately $13.5 million for 850 hybrid transit bus energy storage systems from three leading bus producers in China. The company also is supplying ultracapacitors to several other heavy vehicle OEMs and drive system integrators in the U.S., Europe and Asia, and its sales and applications engineering teams are working with several additional potential customers that are developing and testing ultracapacitor-based systems. "Our initial Chinese OEM customers have placed significant follow-on orders for standard 48-volt BOOSTCAP modules this year, and they are projecting significant additional volumes going forward," Schramm said. "These versatile modules have demonstrated reliable performance and high efficiency in vehicles that have been in service for up to several years. With their ability to be connected in series or parallel configurations to meet various voltage requirements, they can meet the energy storage requirements of virtually any type or size of heavy vehicle. "Working with hybrid vehicle drive system producers around the world has given Maxwell a solid understanding of the requirements of the bus and rail industries and enabled us to expand our global footprint," Schramm added. "Ultracapacitors have become a preferred energy storage option for many types of public transit and commercial vehicles, so we expect these applications to be an even more significant factor in ultracapacitor sales growth going forward." Maxwell's 125- and 48-volt modules include temperature and voltage monitoring and internal cell voltage management that make them easy-to-integrate building blocks for systems with a broad range of voltage requirements.
