Maxwell Technologies Gets Big Ultracapacitor Orders
Wednesday, April 22nd, 2009Maxwell Technologies closed a big deal recently, a purchase order that would amount to $13.5 million worth of BOOSTCAP ultracapacitor modules to support braking energy recuperation and torque assist functions in diesel-electric hybrid transit buses.
David Schramm, Maxwell’s president and chief executive officer, said that deliveries of the company’s 48-volt BMOD0165 P048 modules, which are assembled by one of its contract manufacturers in China, already have begun and will continue through the balance of the year.
Maxwell’s sales and applications engineering teams have been working with heavy vehicle OEMs in China for the past two years. The company estimates that more than 150 hybrid buses with BOOSTCAP ultracapacitor-based energy storage systems already are in service, and that number is now expected to grow to nearly 1,000 by year-end.
“Ultracapacitors’ efficiency in recapturing energy from braking and their low maintenance requirements and long operational life make them an ideal energy storage solution for the demanding duty cycles of electric and hybrid transit vehicles,” Schramm said. “BOOSTCAP modules have demonstrated reliable performance and high efficiency in the first wave of vehicles that have gone into service, and the ability to connect these modules in series to meet various voltage requirements allows for easy integration into virtually any type or size of heavy vehicle.
BMOD0165 P048 modules are encased in a rugged, splash-proof, aluminum chassis. They weigh 14.2kg and are 12.6 liters in volume (416.2mm x 190.1mm x 156.7mm). These durable “smart boxes” include temperature and voltage monitoring and internal cell voltage management that give designers “plug and play” solutions and makes them versatile building blocks for systems with higher voltage requirements.
