UQM Technologies, Inc. announced that Proterra’s EcoRide BE35 battery-electric transit bus will be equipped with a UQM PowerPhase 150 propulsion system.
The 35-foot BE35 battery-electric transit bus is being showcased on a four city California clean bus tour which began in San Jose on February 6th. After San Jose, the bus will make stops in selected California cities including Los Angeles, Sacramento, and San Francisco.
Proterra’s 35-foot EcoRide transit bus seats 37 passengers and features a lightweight composite body. The UQM® PowerPhase®150 electric propulsion system produces peak torque of 650 N-m and peak power of 150 kW (201 horsepower).
The system has a continuous torque rating of 400 N-m and a continuous power rating of 100kW (134 horsepower). The system also features optimized four-quadrant performance, dynamic torque, speed and voltage control, regenerative braking and system energy efficiency of over 90 percent across substantially its entire performance regime.
– TerraVolt Energy Storage System – the industry’s only system that can be fully charged in less than 10 minutes; and the longest lasting energy storage system available for heavy duty applications;
– Flexible ProDrive and vehicle control system that can operate in battery-electric mode or with any small auxiliary power unit (APU) to extend vehicle range when needed;
– All-electric components optimized through vehicle management systems to reduce energy usage throughout the vehicle’s operating cycle;
– Regenerative braking system utilizing the UQM® PowerPhase®150 that enables the EcoRide BE35 to recapture over 90% of the vehicle’s kinetic energy available during braking;
– Sophisticated battery management system operates at the ‘cell’ level to optimize energy efficiency and system life.
