BAE Systems Bus Repair & Maintenance

Expert Support for Hybrid & Electric Fleets Nationwide

Why BAE Systems Technology Matters

BAE Systems bus repair designs and manufactures propulsion and power management systems specifically for heavy-duty transit buses. Their solutions are centered around electrifying bus fleets to reduce emissions, fuel consumption, and long-term operating costs.

The Core of BAE Systems Technology Includes:

Series-E Hybrid Systems: These systems combine a traditional diesel or CNG engine with an electric generator and traction motor to reduce fuel usage and emissions while improving acceleration.
Series-ER Extended Range: Ideal for transit agencies seeking low-emission zones, this system allows electric-only operation for limited distances, with a range extender for longer routes.
Series-EV All-Electric: A fully battery-powered system with zero tailpipe emissions, suitable for cities transitioning to 100% electric fleets.
Modular Energy Storage (ESS): High-capacity battery packs and ultracapacitors that store regenerative braking energy for later use.
Accessory Power System (APS): An efficient method to power onboard accessories like HVAC, lighting, and electronics without relying on the main engine

BAE Systems has become a trusted name in the transit industry due to its performance, reliability, and adaptability to different route profiles. Their products are built for ease of integration with bus OEMs such as New Flyer, Gillig, and Alexander Dennis, making them one of the most widely adopted hybrid-electric technologies in North America.
