Electric drive of mobile apparatus
First Claim
1. A mobile apparatus comprising a main frame with a displacing means, a sub-frame arranged rotatably relative to the main frame, wherein the rotatable sub-frame comprises an operating arm connected to the sub-frame, a first drive configured to drive the displacing means, a second drive configured to drive the operating arm, and a control system, wherein the first drive comprises at least one electric motor such that the first drive is electrical;
- wherein the second drive comprises at least one of an electric motor and an electric actuator;
said mobile apparatus further comprising at least one energy storage unit for storing and supplying electrical energy to the at least one of the first drive and the second drive;
wherein the at least one energy storage unit is coupled to a side, an underside, a front, a rear;
or is positioned in a receiving space of the main frame; and
further comprising operating instruments coupled to a computing unit;
wherein the computing unit is configured to compute the extent to which a plurality of electrical drives is controlled via the control system, wherein at least one of the first drive and the second drive is provided with a sensor for detecting the status of the drive, wherein the computing unit is configured to control at least one drive on the basis of the input of the sensor and the operating instruments and wherein the control system is configured to distribute the available electrical energy over the plurality of drives.
