1. A method for controlling an electric motor driving a hydraulic pump for a battery-powered electric mobile machine, the method comprising:
receiving one or more command signals for a plurality of hydraulically-driven systems;
determining a minimum pump speed for each of the plurality of hydraulically-driven systems required to operate the hydraulically-driven system;
determining a highest minimum pump speed of the minimum pump speeds for the plurality of hydraulically-driven systems;
converting the highest minimum pump speed to an electric motor command; and
sending the electric motor command to the electric motor.
