ePTO power take-off
As of: September 11, 2026
A power take-off (PTO) supplies auxiliary units of a commercial vehicle with energy. In diesel vehicles, this is done mechanically via the engine. In electric commercial vehicles, an electric power take-off, or ePTO for short, takes over this task from the traction battery or a separate tap.
Typical consumers
Refrigeration systems for refrigerated bodies, tail lifts, hydraulic pumps, cranes, high-pressure cleaners, pump units, workshop equipment, and compressors.
The decisive difference to diesel
With diesel vehicles, the engine runs while stationary to power the auxiliary drive. This generates emissions, noise, and fuel consumption without any mileage. With electric vehicles, idling is completely eliminated: the auxiliary drive draws energy directly from the battery. For vehicles with long stationary times and high auxiliary consumption, such as mobile workshops or refrigerated vehicles, this is the greatest operational benefit of the electric drive.
What to consider during design
The energy for the auxiliary drive is drawn from the traction battery and thus reduces the range. A cooling unit in summer operation can account for a significant share of the daily energy requirement. The battery size must therefore be designed according to the driving distance and auxiliary consumption.
Design of the new generation
An electric power take-off is part of the design, complemented by the option to supply consumers directly on the vehicle. HEERO Motors will publish performance specifications after the validation is completed.
