Abstract:
A method for controlling a current distribution between multiple electric motor devices (M1, M2) in a current sharing system(100) of an electrically driven construction machine, a control device which is configured to run said method and a current sharing system(100) for an electrically driven construction machine. The method comprising the steps of: estimating a first current demand for a first electric motor device (M1) powered by a battery system and estimating a second current demand for a second electric motor device(M2) powered by the battery system; determining an available amount of current available in the current sharing system(100); splitting the available amount of current into a first portion for driving the first electric motor device (M1) and a second portion for driving the second electric motor device(M2), wherein the splitting is based on the estimations of the first current demand and the second current demand.
