Parker Chelsea explores potential of ePTOs

A truck’s power needs are not limited to turning the wheels. There are buckets to lift, tools to spin, and more.

Parker Chelsea believes it has an answer as a growing number of vehicles turn to battery-electric power.

The manufacturer has unveiled two integrated ePTOs – the e910 and e970 Series — that can be installed in battery-electric or hybrid-electric vehicles.

The e910 is for lighter duty trucks, with a nominal power output of 10-50 kilowatts, depending on the need and how long the power will be used. And its larger counterpart, the e970, features 70 kilowatts of nominal power for applications such as refuse vehicles.

Teams interviewed chassis OEMs, body builders and end customers to understand requirements such as power, voltage, load, safety, interlocks, and available space, the company says.

“The industry is demanding high efficiency, compact design, ease of installation, as well as flexible speed and torque capabilities to extend the EV’s range,” said Brian Rang, division engineering manager – Chelsea Products Division.

Among integrated features, an internal cooling system allows lubricants to protect subcomponents from overheating, and the ePTOs’ gears allow a higher torque capacity and a compact frame, the company adds. Power-dense Global Vehicle Motors (GVM) also reduce battery size requirements.

Inside the e910 Series ePTO, a Denison Vane Pump can be configured for multiple flow rates and pressures.
