It's the size of an iPad, seamlessly integrated into our custom-designed e-axle, delivering 70kW from our 800V high-voltage platform with zero emissions."

Demystifying the Power Take-Off (PTO) Concept

For those unfamiliar, a power take-off (PTO) functions as a mechanical power output, channeling energy to external machinery such as a dump bed, cherry picker, or plow. In traditional diesel trucks, the PTO typically draws power from the transmission or engine, utilizing the running engine for mechanical force. However, electric trucks lack an idling combustion engine, necessitating power conversion from their battery to mechanical energy for auxiliary equipment. This generally involves incorporating an electric motor and power electronics to drive pumps or other accessories.

Addressing the Challenge of Electric PTO Integration

While companies like Mack and Volvo can integrate electric drive motors with their existing automated transmissions, trucks employing independent electric motors without a transmission, such as the Tesla Semi, face a challenge in providing compatible power for the vast ecosystem of trailers, hydraulic pumps, cherry pickers, cranes, and plows designed for conventional mechanical PTOs.

Windrose's Innovative EPTO Solution

Windrose has pioneered an alternative solution by embedding its EPTO within a compact module directly integrated into the company's proprietary e-axle. This ingenious approach has garnered considerable attention within the industry. Ken North, an emerging technologies consultant for the North American Council for Freight Efficiency (NACFE), lauded the innovation, remarking, "An EPTO has the potential to transform an electric highway truck into a Swiss-Army-Knife of application possibilities, especially here in Canada. Excellent work, Windrose!"
