Already in 2001 AGCO/Fendt recognized the potential of electric drives in agricultural machines and started the MELA (Mobile und Elektrische Leistungs- und Antriebstechnik) research project together with universities and industry partners. The goals were, among others, the development of a compact, high efficient electric machine with durable power converter. After intensive research, development and tests of various high voltage components between 2001 and 2008, Fendt decided to develop a research tractor which is able to generate up to 130 kW electric power to drive electrified implements and electrified auxiliaries. The tractor was ready for operation by the end of April 2012. Since then different field tests with electrified implements have been successfully realized. Currently many research projects and test activities, concerning agricultural machinery, are in progress. Several implement and tractor manufacturers run first prototypes in field tests to learn and understand higher voltage (up to ∼700 V) electric technology and finally to gain experience for series production. Furthermore AEF PG 7 (Agricultural Industry Electronics Foundation; PG 7: Project Group 7 High Voltage) attempts to specify a common electric power interface between the tractor and its implement.
