Classification: CPC E | IPC E

Claim 0:
1. An electric work vehicle, comprising:
a chassis;
an electric traction motor supported on the chassis, the electric traction motor configured to propel the electric work vehicle in a direction of travel;
an implement adjustably coupled to the chassis;
a hydraulic actuator configured to adjust a position of the implement relative to the chassis;
a pump configured to supply hydraulic fluid to the hydraulic actuator, the pump operable within a first operating speed range extending from a minimum operating speed value to a maximum operating speed value, the pump further operable within a second operating speed range extending from a minimum operating speed value to a maximum operating speed 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; and
a sensor configured to capture data indicative of a pressure of the hydraulic fluid; and
a controller communicatively coupled to the sensor, the controller configured to:
monitor the pressure of the hydraulic fluid relative to a predetermined threshold pressure value based on the data captured the sensor; and
control an operation of the pump such that the pump is switched from the first operating speed range to the second operating speed range when the monitored pressure of the hydraulic fluid falls below the predetermined threshold pressure value.
