Abstract
A working machine comprises a direct voltage source (), a first power converter () for transferring energy from the direct voltage source to electric machines () driving actuators of the working machine, an electric connector system () for electrically connecting to an external power grid, a second power converter () for transferring energy from the external power grid to the direct voltage source, and alternating current electric machines () driving auxiliary devices of the working machine. The electric connector system is suitable for connecting the alternating current electric machines to receive alternating voltage of the external power grid, and the second power converter is suitable for transferring energy from the direct voltage source to the alternating current electric machines. Thus, the electric machines driving the auxiliary devices can be energized directly by the external power grid when the working machine is connected to the external power grid.
