Full electric drivetrain for HD vehicles the result of supplier alliance

Engineers at Colorado-based UQM Technologies have collaborated the past several months with their counterparts at Eaton's Vehicle Group and Pi Innovo, both located in Michigan, to develop a full electric drivetrain system for the medium-and heavy-duty EV markets.

Eaton experts are developing and supplying to UQM a 2-speed transmission for an EV (electric vehicle) application, and Pi Innovo engineers are responsible for the transmission control unit. The components are integrated with UQM's current PowerPhase HD220/HD250 motor and inverter system to create a full electric drivetrain system called the UQM PowerPhaseDT.
