Series-EV: Full Battery Electric
Putting all-electric, zero emissions transit solutions within your reach

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.

The zero emissions transit buses you’ve been waiting for are finally at hand. Our dependable, flexible Series-EV system is fully electric, allowing the bus to travel 100% of the time with zero emissions. As the driver accelerates, energy moves from the energy storage system (batteries) to power the motor that drives the wheels (propulsion). To increase the vehicle's efficiency during braking, the motor takes on the role of a generator and recaptures braking energy, storing it in the energy storage system for use later. It's an incredibly efficient, effective system. And, with hundreds of them currently in service in North America and Europe, the Series-EV is a highly reliable, proven battery electric bus system.

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.

Full battery-electric, plug-in city bus

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.

Uniquely integrated installation & support

We provide our customers with the most comprehensive power and propulsion systems integration and support in the industry. While others often just ship their system parts to prime bus manufacturers to install, we've sent a certified Application Engineer along with our cutting edge power systems to make sure they are integrated properly from day one, including on-site technical advice and thorough training. Then we back that work with our Flexible Service Plan – customized to fit the customer's business model – including a coordinated spares management program.
