Bus Manufacturer

Maxwell Technologies, Inc. (Nasdaq: MXWL) announced today that Zhengzhou Yutong Bus Co., Ltd. (Yutong), China's largest bus manufacturer, has selected Maxwell ultracapacitors for energy storage and power delivery in fuel-efficient, low-emission, diesel-electric hybrid buses that Yutong is producing for public transit agencies worldwide.

Yutong's hybrid drive system incorporates 16 of Maxwell's 48-volt ultracapacitor modules to support braking energy recuperation and torque assist functions that enable hybrid transit buses to achieve fuel savings and CO2 emission reduction of approximately 25 percent and reduce particulate emissions by up to 90 percent compared with conventional diesel buses.

"Ultracapacitors' ability to charge and discharge rapidly enables them to efficiently capture regenerative braking energy and provide instant power for acceleration," said Wang Feng, Yutong's overseas marketing director. "In addition, their long operational life and minimal maintenance requirements in demanding public transit operating conditions make ultracapacitors a very cost-effective energy storage solution for hybrid buses."
