DYNO TESTING & EARLY RESULTS
Jan 2016 - Using proceeds from a variety of recent business plan and innovation competition wins, Hyliion has begun testing the prototype suspension system on a dynamometer at the Pittsburgh Power testing lab. Early results have come in and we are excited to see our early projections are well within reach.
A dynamometer measures force, torque and/or power that a engine puts out. Using complex mathematical models and forecasting software, Hyliion initially predicted an additional torque of 500 ft. lbs. provided by the suspension system, in addition to a 30% reduction in on-the-road fuel consumption and up to 30 hours of passive power supply while the truck is parked.
In these tests, resistance was applied to the suspension and the batteries were calibrated to apply 500 amps to the motor. Under these conditions, the system supplemented the truck's engine with an additional 550 ft. lbs. of torque, and obtained wheel speeds of Oto 41 mph with no additional help from a tractor engine, and sustained over the course of a 20 second timeframe.
After exceeding expectations forecasted from the software models, we are excited to begin testing the system under live road conditions with loaded trailers.
