The Covid-19 pandemic crisis has accelerated the integration of innovation and sustainability, so much so that, by now, they have become two priorities that travel together and are affecting more and more areas of our lives.

In the current context, a request came in from one of our historical agriculture customers for a turnkey project to be developed totally in-house: hybridize one of their agricultural machine models.

Directly the customer’s R&D area then asked us to find the best solution for a special operations tractor, which, through the help of an electric motor, would be able to give power to operating machines (e.g., seed drill, spraying machine, chopper) without taking it from the engine, therefore, without consuming fuel.

The goal was to realize a wiring harness that could fulfill the two main functions: delivering power and connecting the plant for the control system.

Delivering the power required connecting the inverter, electric motor, 48V battery pack, and power sockets; whereas, making the plant for the control system involved us designing a structure for installing the control units and the sensor connection line so that the customer’s control software would work.

Having defined the tractor model to be electrified, the customer provided the pinout with all the electronic connections and the data sheet of the various components such as the control units, electric motor, battery, inverter, sensors, DC/DC converter, and power outlets.

Starting from the available material, the team consisting of 3 of our designers, made the 3D model of the wiring harness using CREO CAD. Thanks to the faithful reproduction of the 3D, it was possible to find the optimum in the positioning of the various necessary elements, such as the control units, arrangements for the display inside the cabin, and for sensors and connectors too.

We then proceeded to the realization of the 2D wiring diagram of the system using Vesys software. During this phase, the size of the cables differing in power and signal was defined, the protection system connected to the battery cut-off was sized, and finally a schematic realization of the cables was presented that was already suitable for their production.

At the conclusion of the project, we studied and defined how to integrate the hybrid system with the vehicle’s mechanical system.

In just three months, our designers came up with a finished electrification system that reduces emissions, meets customer requirements and opens up to multiple new usage scenarios.
