Claim 15:
16. A method for controlling a pump operating speed range of an electric work vehicle, the electric work vehicle including a pump configured to supply hydraulic fluid to a component of the electric work vehicle, the electric work vehicle further including an electric pump motor configured to rotationally drive the pump, the method comprising:
receiving, with one or more computing devices, sensor data indicative of a pressure of the hydraulic fluid;
monitoring, with the one or more computing devices, the pressure of the hydraulic fluid relative to a predetermined threshold pressure value based on the received sensor data; and
controlling, with the one or more computing devices, an operation of the electric pump motor such that the pump is switched from a first operating speed range extending from a minimum operating speed value to a maximum operating speed value to the second operating speed range extending from a minimum operating speed value to a maximum operating speed value when the monitored pressure of the hydraulic fluid falls below the predetermined threshold pressure value, the maximum operating speed value of the first operating speed range being greater than the maximum operating speed value of the second operating speed range, the minimum operating speed value of the first operating speed range being greater than the minimum operating speed value of the second operating speed range.
