Defence contractor BAE Systems and global power management company Eaton have joined forces to develop an electric vehicle system (EV) for medium-duty trucks.

Announcing the move, the joint venture said it is already developing a Class-7 pickup and delivery demonstration vehicle.

The EV system will incorporate BAE Systems’ power-dense electric motor and advanced silicon carbide/gallium nitride power electronics suite with Eaton’s MD 4-speed EV transmission.

BAE Systems said the EV system will provide OEMs with “a durable, high performance, compact, efficient, and optimized system with flexibility to work with multiple zero-emission platforms.”
