Abstract
A method for controlling an electric motor driving a hydraulic pump for a battery-powered electric mobile machine includes receiving one or more command signals for one or more hydraulically-driven systems. The method also includes determining a minimum pump speed for each of the one or more hydraulically-driven systems, and determining a highest minimum pump speed for the one or more hydraulically-driven systems. The method further includes converting the highest minimum pump speed to an electric motor command, and sending the electric motor command to the electric motor.
