Electric propulsion systems leader BAE Systems has been selected by the Toronto Transit Commission to provide more than 335 electric drive systems for its new fleet of zero-emission capable hybrid transit buses. This follows an order of 165 additional Series-ER systems for nearby Mississauga Transit MiWay, supplying Ontario transit agencies with next-generation technology to reduce fuel use and enable infrastructure-free zero emissions operations across its fleets.BAE Systems’ Series-ER system offers significant zero emission capabilities to assist a transit agency’s transition to a full zero-emission operation. Series-ER features the company’s next-generation components that use advanced materials and a lightweight, compact design to increase electrical efficiency. The Ontario fleet orders extend the footprint of the company’s technology to more than 15,000 transit buses worldwide.The Series-ER system includes an electric motor, onboard energy storage, and smart controls to create a clean, integrated electric propulsion and accessory power system for the buses. In addition, the buses will feature BAE Systems’ proven engine stop and start function and geofencing technology, allowing an electric-hybrid bus to automatically switch to full electric bus mode when entering designated green zones. The system uses advanced energy recovery and an onboard charger to further deliver zero-emissions operation without the need for grid-connected charging.The production and service support for the Series-ER systems will be conducted at the company’s facility in Endicott NY.
