UQM Technologies Power-Assist Hybrid System

UQM Technologies Inc. has a 42V power-assist hybrid system for light and medium duty trucks, sport utility vehicles, and off-road vehicles. The starter motor generator system mounts directly to the engine crankshaft and delivers 710 Newton-meters of engine starting torque, 10kW of power-assist in motoring mode, and peak power generation of 15kW engine operating speeds from 1,200rpm to 2,800rpm.

The unit, which can also be configured to deliver a variety of speed/torque profiles, measures 4 inches in length and 16 inches in diameter, excluding the flywheel housing, and is designed to be fully integrated into the flywheel of an engine. The system also features a controller area network (CAN)-compatible UQM® power electronic digital controller that intelligently manages the system’s operation including the dynamic application of the power-assist motoring function and regenerative braking function.

The power-assist feature provides up to 10kW of acceleration power to the engine for a short duration during high engine load conditions. Additional features of the system include high-speed engine start capability, regenerative braking, and higher levels of onboard electrical power to handle larger electrical loads from accessories.
