Hybrid Applications

Working over 20 years Eaton has commercialized two distinctly different parallel hybrid systems that today are available through commercial truck and bus manufacturers worldwide. Each system significantly reduces vehicle fuel consumption and emissions output, and provide other benefits like reduced maintenance and brake replacements costs and noise reduction at work sites.

In general, electric hybrid systems have high energy storage capacity due to their battery pack and the release of energy from the battery can be slowed and easily controlled over time. Hydraulic hybrid systems can release power much quicker but for a shorter length of time before needing to be recharged.


Deciding whether or not to invest in a hybrid technology or determining if it’s the right for your intended use boils down to the vehicle’s duty cycle. Generally speaking, if the vehicle does a lot of short- range, start-and-stop driving under low average speeds and/or it requires a high level of engine idle time  where they hybrid system is frequently engaged  then it would be a good fit for a hybrid application. However, if the vehicle spends over half of its operating time at steady-state highway speed; it would not be a good fit for a hybrid application.

Eaton has done extensive study of both electric and hydraulic hybrids technologies in a wide variety of applications indicating that there is significant opportunity for its hybrid offerings. The areas we chosen to focus on are:
