Working machine with a hybrid energy supply concept consisting of grid operation and small-scale energy storage

Abstract

A working machine with an electric drive and a power supply unit, comprising an electrical energy storage device and an interface for connection to an external power supply unit, characterized in that a charging device is provided whose maximum charging power LL is at least equal to or exceeds the electrical power consumed by the working machine during operation, defined as cycle power ZL, and that the energy storage device has a capacity AK for which AK / ZL ≤ 1 in relation to the cycle power.
