Abstract
Hydraulic load management for electric motor driven systems, such as hydraulic systems in a work machine, is disclosed. The hydraulic system may include an electric motor coupled to a hydraulic pump to provide hydraulic fluid to a hydraulic actuator, and a power bus may connect an electric power source to the electric motor. Hydraulic load management may include determining an actual electric power available at the electric power source, comparing the actual electric power to a threshold electric power for operating the electric motor at a full capacity, and setting a value for an available electric power and a current power curve for the electric motor corresponding to the available electric power. When hydraulic system input is detected, electric power is provided via the power bus, and the electric motor is operated at a motor speed based on the current power curve and a commanded speed from the hydraulic system input.
