Abstract

A refuse vehicle includes a battery configured to provide electrical energy to drive at least one of a plurality of wheels, a vehicle body supported by the chassis and defining a receptacle for storing refuse therein, and an electric power take-off system including a motor configured to power to a hydraulic system in response to receiving the electrical energy from the battery, an inverter configured to provide the electrical energy to the motor from the battery, a sensor configured to detect thermal energy within the inverter, and a controller configured to receive data from the sensor, wherein the controller is further configured to determine if the data from the sensor is greater than a critical operating condition and reduce a rate of electrical energy supplied to the motor in response to determining that the data from the sensor is greater than the critical operating condition.
