Power Interface Specification for Electric Power Take-Off Systems (ePTO) Finalized

The automotive industry is taking a significant step forward in its transition towards electrification with the development of the ePTO (Electric Power Take-Off) Specification. This innovative interface, developed by ACEA, allows vehicle body builders to power their equipment directly from the energy storage of an electrified vehicle propulsion system.

The ePTO Specification focuses on a customer-pluggable DC connection between trucks and trailers/semitrailers, offering numerous advantages for increased fuel efficiency, reduced emissions, and enhanced versatility. The specifications provided are for the prototyping and test phase, with three power classes proposed: 25kW, 50kW, and 100kW, at an operating voltage of up to 1000V.

The ePTO Specification includes physical and logical interface requirements for interoperability and cross-compatibility for systems and equipment. Detailed information on the high-voltage and signaling interfaces can be found in corresponding specification sheets, including the ePTO Specification Signalling V1.0.0 and the ePTO technical supplement V1.0.0, both of which are available for download.

The ePTO enables the efficient supply of electricity for various applications without relying on a separate generator or running the main engine. This contributes to a more sustainable and efficient transportation system, aligning with global efforts to reduce carbon emissions and improve fuel efficiency.

Interested parties are invited to support the next phase of the ePTO connection implementation. To be part of this exciting development, please send an email to Mr. Armin Keller at epto@our website. However, the responsible party for the next phase of the ePTO connection implementation has not been specified in the provided information.

The ePTO is a significant milestone in the electrification of heavy-duty vehicles (HDVs), including hybrids, battery-electric, and fuel-cell vehicles. As the industry continues to evolve, the ePTO Specification is expected to play a crucial role in shaping the future of sustainable transportation.
