Maxwell Technologies delivers ultracapacitor-based regenerative braking energy storage for Beijing subway system
27 July 2016
Maxwell Technologies, a leading developer and manufacturer of ultracapacitor-based energy storage and power delivery solutions, announced that its ultracapacitors are used for regenerative braking energy storage in the Beijing subway system. As part of the strategic partnership with China Railway Rolling Stock Corporation (CRRC-SRI) Maxwell announced last year, the companies continue to collaborate to develop next-generation capacitive energy storage solutions for the China rail market.
The installation with the Beijing subway system is the first commercial subway wayside project for CRRC-SRI and Maxwell in China. CRRC-SRI will leverage Maxwell’s 48-volt modules in two sets of regenerative braking energy storage devices for the system’s No. 8 line, an urban rail network that runs north-south through China’s capital, one of the most populous cities in the world.
Maxwell ultracapacitors deliver high-power energy density performance, even under extreme temperatures. With long operational lifetimes and rapid charge/discharge capabilities, the modules are suited for rail transportation applications. The Beijing subway system implementation is among many global transportation applications relying on Maxwell technology, including rapid braking, energy recuperation and power delivery for rail, as well as start-stop applications for automobiles and hybrid buses.
