Solution provider BAE Systems and hi-tech specialist Eaton have successfully tested their integrated electric drive system for medium- and heavy-duty commercial trucks. Using this technology, existing truck models can be easily 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 cooperation between BAE Systems and Eaton

The vehicle met key on-road performance goals, including gradeability and highway speed, all within a single electric vehicle (EV) system. BAE Systems’ electric motor and suite of modular power electronics is combined with Eaton’s MD 4-speed EV transmission to create a comprehensive 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 demonstration truck will be on display at the 2024 ACT Expo.

“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.”
