Ultracapacitors Are Adopted in Hybrid Buses

Maxwell Technologies has announced that Golden Dragon Bus Co., a producer 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.

According to David Schramm, Maxwell's president and chief executive officer, Maxwell has completed delivery of 720 48-V BMOD0165 P048 multi-cell ultracapacitor modules to Golden Dragon for installation into 45 hybrid buses ordered by the Hangzhou Public Transport Group Co.

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.
