Update: UQM Powertrain for Series Propane-Electric Hybrid Shuttle

As noted in a previous post, a series hybrid electric shuttle bus powered by a UQM propulsion system is under test by a Tier One supplier.

A Ford LSG 642 (6 cylinder, 4.2-liter) engine fueled by propane drives the generator. Maximum output at 2200 rpm (the UQM operating speed) is about 55 kW.

The electric motor is a standard UQM Powerphase 100 offering 100 kW (134 hp) of motoring power and 550 Nm (406 lb-ft) of peak torque. A similar unit functions as the generator.

The batteries are a 30 Ah Lithium Polymer type, with nominal voltage of about 336V. They have a peak discharge capacity of about 10C, with very low resistive losses. According to UQM, temperature effects have been minimal—the company characterizes the performance as excellent.

Regenerative braking produces up to 60 kW at high speeds.

The companies have yet to perform extensive emissions testing on the integrated platform.
