Abstract: An accumulator system has a high-voltage accumulator for mobile work machines. A battery management system, has a controller-line connections which can be switched by switches; and a data bus for connection to a work machine control unit. In order to advantageously render an electrical-system battery unnecessary, the battery management system comprises, for voltage supply, a DC-DC converter which is located upstream of the controller in terms of current flow and which is connected to the high-voltage accumulator via a standby circuit. The standby circuit can be activated by a circuit that is external to the accumulator system.

Abstract: A bent-axis machine comprises a housing having a control cover and a piston drum which is rotatably mounted in the housing on a valve plate and which has axial cylinders, each of which receives a piston. An adjustment system includes a pivot cradle via which the piston drum and the valve plate can be pivoted relative to the drive axis about a maximum working range which is delimited by a minimum pivot angle and a maximum pivot angle. The minimum pivot angle of the working range is shifted out of its zero position by at least 5°, and the maximum pivot angle is extended in the same way by at least 5° in order to retain the entire working range about the region left out of the lower region.
