FIELD: machine building.
SUBSTANCE: invention relates to a mobile working machine with a full electric drive. Mobile working machine includes a lower bogie having a caterpillar, rail or wheel propulsor, an upper bogie having a working equipment fixed on it, a rotary circle which connects the lower bogie to each other and a rotatable upper trolley, a decentralized power supply network for powering the mobile working machine, and a contact ring for transmitting electrical energy between the upper trolley and the lower trolley. There is an energy accumulator electrically connected to the contact ring and made in a decentralized manner from several energy accumulation units. At the same time all wires for connection to decentralized energy accumulators have approximately the same resistance of wires.
EFFECT: reduction of required primary energy consumption and provision of optimum arrangement of energy accumulators.
