Device for transferring electrical energy from an agricultural work vehicle to an extension device which can be coupled onto the work vehicle

The invention relates to a device for transmitting electrical energy from an agricultural work vehicle (10) to an attachment (26) which can be reversibly coupled to the work vehicle (10). The device comprises at least one power electronics (38, 74) arranged on the work vehicle side, at least one electrical work vehicle interface (36) and at least one electrical implement interface (34). The power electronics (38, 74) can be fed with electrical energy which can be generated by a generator (16) of the work vehicle (10). The power electronics (38, 74) is electrically connectable to the generator (16) and to the work vehicle interface (36). The attachment (26) has at least one attachment interface (34) and at least one electrical load (30, 102, 104). With the electrical load (30, 102, 104) of the attachment (26) an agricultural work function is executable. At least one working vehicle interface (36) can be coupled to at least one attachment interface (34), and via this at least part of the electrical energy generated by the generator (16) of the work vehicle (10) can be transmitted to the attachment (26) via the work vehicle interface (36).
