A Combination of Superior Batteries and Vehicle Control

Pittsburgh-based Hyliion is aiming for fuel savings as great as 20% for heavy over-the-road trucks using a combination of advanced lithium ion battery packs for regenerative braking and idea reduction, and software that adjusts a truck’s driveline output based on the road conditions ahead. updated November 8

Pittsburgh-based Hyliion is aiming for fuel savings as great as 30% for heavy over-the-road trucks using a combination of advanced lithium ion battery packs for regenerative braking, and algorithms that adjust a truck’s driveline output based on the road conditions ahead.

What’s new about it? “The batteries that we’re using on our systems and the computer algorithms,” says Hyliion founder and CEO Thomas Healy.

‘The Hyliion system can be installed in less than one hour,’ the company says.

Hyliion has developed “sub-ambient” temperature lithium ion battery packs capable of rapid charging and discharging, he told F&F, making a given truck’s regenerative braking system more efficient.

Reduced Maintenance Costs

Proprietary algorithms take into account weather and road gradients for more efficient management of the battery system and maximum electric power to the drive wheels.

The Hyliion package also includes “improved trailer analytics” and an aerodynamics package that significantly reduces air resistance.

And, “by shifting some of the mechanical stress of braking onto the Hyliion system, brake pads and engines will go further and last longer, requiring less maintenance and fewer replacements,” the company says.

Idle Reduction

“An additional fuel conservation component” is idle reduction, and the Hyliion system functions as an APU/auxiliary power unit while drivers rest.

Thus the truck’s diesel engine does not have to run during the night, thereby saving fuel. “An industry-leading APU manufacturer estimates a truck idles 2500 hours at rest stops each year, or a little over 8 hours a day, 300 days a year,” Hyliion says.

“This idling burns about 1.2 gallons of fuel every hour resulting in 3,000 gallons of diesel fuel, or 13.5% of total fuel consumed, being wasted at rest stops each year.

A long way to go but fantastic potential
