The German company, ZF, has been chosen by the British bus manufacturer Alexander Dennis Ltd (ADL) to supply the electric drive for a brand new fuel cell bus.

ADL spent two years developing this hydrogen-driven double-decker bus with ZF selected as a partner right from the start. During field testing, the prototype operated along real bus routes in several cities throughout the United Kingdom. The Enviro400 design impressed everyone with its outstanding efficiency.

In addition to the electrif drive axle (AxTrax AVE), ZF also provided the inverter, the EST 54 electronic control unit and the appropriate control software. In this complete system, the company optimally aligned performance, efficiency and the service life of the drive. Moreover, this system solution helped reduce the test and homologation costs for ADL.

The British manufacturer has already presented the prototype of the new fuel cell double-decker to the public as well as several fleet operators.
