Series-EV: Fully electric

Why Series-EV?

  • Shares common components with Series-E and Series-ER
  • An upgrade from Series-ER
  • Enables fully electric options:
    • full-battery electric
    • hydrogen-fuel cell
    • en route and overnight charging
    • inductive and conductive charging
  • Electric trials today operating in: London, Glasgow, Paris, and Walnut Creek.

Our series hybrid is fully electric—100 percent of the traction power is delivered electrically via a direct drive electric motor powering the wheels of the bus. The engine and generator provide some of the power but the same drive-line components can be used to provide fully-electric propulsion without the need for an engine.

We are actively working on fully-electric vehicles (EV) with city bus manufacturers in Europe and North America. We believe flexibility is a key driver in the transport requirements of modern cities. Full-EV battery buses offer an important solution, but they require significant charging infrastructure investment, and they need scheduled down-time to charge their large batteries. While these buses can be used on certain routes, some routes are not well suited to battery buses. In these scenarios, battery dominant and/or plug-in hybrids can be used to bridge the gap.

With major cities like Paris announcing that their fleets will be 100% green by 2025, we are working with Iveco Bus on a fully-electric city bus concept. With no engine and using a plug-in charge, this solution offers zero tailpipe emissions while maintaining passenger capacity and operational range.
