Electric propulsion system supplier BAE Systems, which has a defense division in Sterling Heights, recently unveiled its next-generation full-battery-electric power and propulsion system for transit buses.

The new system – called the Series-EV – offers cities around the world an opportunity to get to zero transportation emissions and improve the range and efficiency of their electric transit bus fleets.

The Series-EV builds on BAE’s core technology used in hybrid vehicles but eliminates the need for a combustion engine to drive the bus. Instead, it uses electric motors, controls, and batteries to create a clean and emission-free mode of public transportation.

“Many cities are striving to get to zero emissions with their bus fleets and we are committed to supporting them with all-electric solutions that meet their needs and exceed their expectations,” says Steve Trichka, vice president and general manager of power and propulsion Solutions at BAE Systems. “Our Series-EV system provides operators with a highly reliable and low-cost battery electric option that not only gives them more flexibility and capability but allows them to completely eliminate emissions on their bus fleets.”

Trichka says the Series-EV uses fewer, lighter, and more-compact components to make it easy to install and reduce the need for future maintenance. The system’s light weight and reduced number of connections help to make the most of its power and paves the way for buses to travel longer distances on a single charge. The design also allows operators to customize based on their propulsion or accessory power requirements. Larger buses would require more traction power, for example, and the addition of air conditioning on the bus would increase the accessory power needed.

BAE Systems has more than 10,000 electric-hybrid systems in service around the globe including major cities such as Paris, London, New York, and San Francisco. Every year its systems travel more than 330 million miles and transport nearly 2 billion people.
