Much of the focus on electrifying commercial trucks has been on optimizing electric powertrains and solving challenges like battery capacity, maximum battery voltage, eAxles and safety considerations. Long haul trucks present significant challenges to electrification due to battery size & cost and charging infrastructure.

A quicker path to electrification is often for work trucks – commonly Class 5-8 vehicles that utilize hydraulics, pneumatics, vacuum, water pumps, etc to perform vocational work off of the truck chassis.

Commercial work trucks have historically utilized mechanical Power Take Off units (PTOs) to transfer power from the diesel engine and transmission to operate hydraulic, water, vacuum pumps, pneumatic compressors, etc. An ePTO replaces the traditional mechanical PTO for electrified vehicles. ePTOs are a broad term and represent many implementations and form factors, which can be confusing, but the benefits include reduced engine runtime reduction, lower emissions and fuel and maintenance savings.

Watch this session to learn about:
• The various types of ePTOs and the rationale when considering which ePTO to specify
• The advantages of using ePTOs with vehicles with and without an ICE engine
• Typical power requirements, safety issues, and integration considerations
• Architecture considerations to maximize efficiency and battery power conservation
