UQM Technologies, Inc. has completed an agreement with Proterra Inc. to supply UQM PowerPhase 150 electric propulsion systems for use in Proterra’s all-composite fast charge battery electric transit buses. The initial term of the supply agreement is one year.
Deliveries totaling $627,500 are scheduled to begin in October. Additional deliveries permitted in the agreement during its one-year term could raise the total value of the contract to more than $1 million.
Proterra has been developing and manufacturing energy efficient commercial vehicle technologies since 2004. Proterra’s latest transit bus, the zero emission all-electric EcoRide BE-35, holds 68 passengers (37 seated), and features a lightweight composite body. The bus also incorporates the TerraVolt fast charge energy storage system from Altair Nanotechnologies (earlier post), which includes proprietary battery modules and packs and a battery management and energy optimization system that can be charged to full capacity in a matter of minutes using a Proterra on-route FastFill charging station.
The UQM PowerPhase 150 electric propulsion system produces peak torque of 650 N&iddot;m (479 lb-ft) and peak power of 150 kW (201 hp).
