Operation Assistance Device and Operation Assistance Method for Electric Work Machine

Abstract

This disclosure provides an operation assistance device capable of suppressing degradation and increasing a life of battery of an electric work machine. An operation assistance device 1 allocates a plurality of electric work machines EWM1, EWM2, . . . , EWMn to a respective plurality of work sites WS1, WS2, . . . , WSn. The operation assistance device 1 includes an information storing section 11 that stores each piece of information on a workload of the plurality of work sites WS, a state acquiring section 12 that acquires a degradation state of a battery B mounted in each of the electric work machines EWM, a state predicting section 13 that calculates a predicted degradation state of the battery B when each of the electric work machines EWM works at each of the work sites WS, and an operation planning section 14. The operation planning section 14 selects the work sites WS in a descending order of the workload based on the information stored by the information storing section 11, and allocates a specific electric work machine EWM among the plurality of electric work machines EWM1, EWM2, . . . , EWMn to the selected work site WS based on the predicted degradation state.
