Eaton has made a series of upgrades to its hybrid power systems for trucks. Among the most significant modifications there is a more performant battery, a higher capacity clutch and a new single phase 115 volt AC auxiliary Power Generator (APG).

Thanks to the new lithium-ion battery the fuel efficiency of the system was increased with up to 10 %. Moreover, the new battery more than doubles the engine-off capability of the system and extends battery life.

Kevin Beaty, product strategy and manufacturing operations and strategic sourcing manager, hybrid power systems for Eaton said, “Not only will fleets realize greater fuel efficiency and reduced C02 emissions, but drivers will notice faster acceleration with the updated hybrid propulsion system. The new battery is designed to allow for simplified servicing of internal components.”

The new APG is smaller and 25 lbs lighter than the previous model, so it will be easier to install. Talking about the new APG, Gerard DeVito, engineering director said, “The new APG unit offers a soft-start function that can handle high inrush loads that require an immediate boost of power. The APG is also a fully isolated system from the high-voltage battery, which eliminates the need for a separate isolating transformer to further reduce cost and weight.”

The high-capacity battery and APG will be available from the fourth quarter of this year for serve utility applications and the new battery will be also introduced for beverage tractor applications in the third quarter of 2012.

Besides the aforementioned upgrades, the company also offers more performant clutches that can deal with engines up to 860 lb-ft of torque and 300 HP.

The company has announced that it will start to offer remanufactured batteries in July which will be significantly cheaper than the new ones.
Beaty declared, “Fleets can now extend the life of their hybrid power system for a fraction of the cost of new service units. Our goal is to provide the greatest possible value to hybrid customers who want more sustainable fleets at the best possible cost.”
