Golden Dragon Bus Co. Ltd., one of the world’s leading producers of medium- and heavy-duty buses, has selected Maxwell’s BOOSTCAP ultracapacitors for braking energy recuperation and torque assist in fuel-efficient, low-emission, diesel-electric hybrid buses Golden Dragon is producing for the Hangzhou, China, Public Transport Group Co., Ltd.
Golden Dragon delivered the first prototype hybrid bus with an ultracapacitor-based energy storage system to Hangzhou in July 2007, for comparison with other hybrid drive systems under actual operating conditions.
Maxwell has completed delivery of 720 48-volt BMOD0165 P048 multi-cell ultracapacitor modules to Golden Dragon for installation into 45 hybrid buses ordered by the Hangzhou Public Transport Group Co., Ltd.
BMOD0165 P048 modules are encased in a rugged, splash-proof, aluminum chassis. They weigh 14.2 kg 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.
