BAE Systems and Eaton said they successfully tested their integrated electric drive system for medium- and heavy-duty commercial trucks. Using this technology, the companies said existing truck models can be adapted across various zero-emission applications, improving efficiency, performance and flexibility.

Testing occurred at Eaton’s proving grounds in Marshall, Michigan on a Class 7 demonstration vehicle. The vehicle met key on-road performance goals, including grade ability and highway speed, all within a single electric vehicle (EV) system. The compact system helps increase electrical efficiency and reduce vehicle weight.

“Our robust solution is built on proven technology to meet the unique demands of EV trucks,” said Bob Lamanna, vice president and general manager of Power & Propulsion Solutions at BAE Systems. “This integrated approach simplifies the complex electric drive system for trucks and commercial vehicles.”

BAE Systems’ electric motor and suite of modular power electronics are combined with Eaton’s MD 4-speed EV transmission to create a system for commercial vehicles. It can also be fitted with Eaton’s HD-4 EV transmission, offering a full line of electric drive systems for commercial trucks above 19 tons.

The BAE Systems and Eaton system give original equipment manufacturers a durable and optimized electric drive solution for a wide range of platforms, the companies said. Due to the architecture, it uses a reduced number of components, cables, and connections, saving space and weight on the vehicle.

BAE Systems said it has more than 17,000 propulsion systems operating in transit buses, boats, military, and industrial vehicles across the globe with over five billion miles of proven performance.
