Method For Controlling A Current Distribution, Control Device For Running Said Method And Current Sharing System

摘要

A method for controlling a current distribution between multiple electric motor devices in a current sharing system of an electrically driven construction machine is described. The method comprises estimating a first current demand for a first electric motor device powered by a battery system and estimating a second current demand for a second electric motor device powered by the battery system. The method comprises determining an available amount of current in the current sharing system. The method comprises splitting the available amount of current into a first portion for driving the first electric motor device and a second portion for driving the second electric motor device. The splitting is based on the estimations of the first current demand and the second current demand. A control device configured to run the method and to run a current sharing system for an electrically driven construction machine is also described.
