UQM Technologies has begun a development and production program with Eaton’s Vehicle Group and Pi Innovo, both located in Michigan. The alliance calls for Eaton to develop and supply to UQM a 2-speed transmission for an EV application, and Pi Innovo will develop and supply to UQM the transmission control unit. Together, the components will be combined with UQM’s current PowerPhase HD220/HD250 motor and inverter system to create a full electric drivetrain system called the “UQM PowerPhaseDT .” The benefits of the system will allow customers in the medium and heavy-duty EV commercial markets to achieve increased performance in areas of gradability, acceleration and efficiency. The Eaton 2-speed transmission provides a greater speed and torque range from what would normally be possible in a direct drive system, allowing a smaller electric motor to drive large vehicles.
