New Partnership with Eaton and Pi Innovo for ‘PowerPhaseDT’
Including Include Motor, Two-Speed Transmission and Inverter:
Combination Intended for Larger & Cheaper Electric-Drive Vehicles

Colorado’s UQM Technologies has disclosed a new alliance with Eaton and Michigan’s Pi Innovo to develop a full electric drivetrain system using UQM’s PowerPhase HD220/HD250 motor and inverter.

“Supplier relationships with Eaton and Pi Innovo will allow UQM to meet the growth projections of the EV commercial global market including China, Europe and South America,” states a release.

UQM’s PowerPhase HD220/HD250 motor and inverter will be the basis of the new UQM PowerPhaseDT including twospeed transmission by Eaton with a Pi Innovo control unit.

The UQM package is to be combined with a new two-speed transmission from Eaton and a transmission control unit from Pi Innovo. The full electric drivetrain system will be called the “UQM PowerPhaseDT.”

Smaller Motors

UQM says it will have prototypes ready for customers by early fall and start-of-production units ready by early 2017.

Benefits will include better hill-climbing, acceleration and efficiency, as the new two-speed transmission will provide greater speed and torque range from that of a direct drive system, allowing for a smaller electric motor to drive large vehicles. UQM expects improvements in packaging, efficiency, payload capacity and cost compared with direct drive or single-speed drivelines.

“Perhaps the biggest benefit is the fact that the two-speed transmission keeps the electric motor operating in the highest efficiency region for a greater portion of the drive cycle,” UQM technology VP Josh Ley says in the partnership announcement. ,


Smaller Battery Packs

“This, coupled with the extremely high efficiency of the ‘UQM PowerPhaseDT’ electric drivetrain system, will enable the highest overall vehicle efficiency, saving cost in batteries and increasing range,” he said.

“Pi Innovo’s hardware, software and applications engineers have worked closely with the UQM team to optimize the performance of the system to meet the efficiency requirements demanded by UQM’s customers,” said Pi Innovo Walter Lucking. “Working with UQM has been a great experience for our team,” he said.

“This system will help vehicle manufacturers ensure they are providing a product that helps them improve vehicle efficiency without compromising performance,” said Marco Rollero, Eaton vehicle group EMEA sales and marketing director.

An ‘Overarching Need’

“We have done extensive market research and believe that this offering will be the ideal drivetrain solution for electric and range-extended commercial vehicles,” said UQM president and CEO Joe Mitchell.

“The development and production of a full electric drivetrain system will support the overarching need for full transmission systems as enhanced performance and efficiency requirements are mandated by customer drive cycle needs as well as the need to reduce battery costs and meet more stringent environmental regulations,” UQM says.
