Abstract: A fault detection system and method includes a sensor; a processing unit; and an output unit. The sensor is configured to acquire temperature data at a sensor location of a device, wherein the temperature data comprises first temperature data and second temperature data acquired a first time period after the first temperature data. The processing unit determines a temperature magnitude comprising utilization of the first temperature data and/or the second temperature data, and determines a rate of change of temperature. The processing unit predicts a temperature at a location of the device using the temperature magnitude, the rate of change of temperature, and a correlation, wherein the correlation is a correlation of a plurality of temperature magnitudes and a plurality of rate of change of temperatures at the sensor location with a plurality of hotspot temperatures at the location.

Abstract: An electric work vehicle includes a hydraulic actuator and a pump configured to supply hydraulic fluid to the hydraulic actuator, with the pump being operable within an operating speed range extending between a minimum operating speed value and a maximum operating speed value. Furthermore, the electric work vehicle includes a sensor configured to capture data indicative of a temperature of the hydraulic fluid and a controller communicatively coupled to the sensor. As such, the controller is configured to monitor the temperature of the hydraulic fluid relative to a predetermined minimum fluid temperature as the pump is operating within the operating speed range. In addition, the controller is configured to adjust the operating speed range of the pump by increasing at least one of the minimum operating speed value or the maximum operating speed value when the monitored temperature of the hydraulic fluid falls below the predetermined minimum fluid temperature.
