1. A refuse vehicle comprising:
a chassis supporting a plurality of wheels;
a battery configured to provide electrical power to selectively drive at least one of the 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 coupled to the vehicle body, the electric power take-off system including:
a motor configured to convert electrical power received from the battery into hydraulic power,
an inverter configured to provide electrical power to the motor from the battery;
a heat dissipation device in thermal communication with the inverter, wherein the heat dissipation device includes a plurality of conduits and a thermal fluid pump configured to pump cooling fluid through the plurality of conduits,
a flow meter configured to detect flow rate data corresponding with a flow rate of cooling fluid through the plurality of conduits, and
a controller configured to receive the flow rate data from the flow meter and provide operating parameters for controlling the heat dissipation device to the heat dissipation device, wherein the controller is further configured to determine if the flow rate data from the flow meter is less than a critical operating condition and decrease the hydraulic power provided by the electric power take-off system in response to determining that the flow rate data from the flow meter is less than the critical operating condition.
