Abstract

A refuse vehicle includes a chassis, a body assembly coupled to the chassis, and a thermal stress mitigation system. The body assembly defines a refuse compartment. The thermal stress mitigation system is configured to mitigate against a thermal stress on the refuse vehicle. The thermal stress mitigation system includes a thermal stress mitigation substance, at least one of a container and a tank, one or more nozzles, a controller, one or more thermal sensors. The controller is structured to receive thermal stress data from the sensors, determine whether the thermal stress is greater than a threshold thermal stress based on the thermal stress data from the sensors, and operate the nozzles to deploy the thermal stress mitigation substance on the refuse vehicle responsive to determining that the thermal stress is greater than the threshold thermal stress.

First claim

1 . A refuse vehicle comprising:
a chassis; a body assembly coupled to the chassis, the body assembly defining a refuse compartment; a thermal stress mitigation system configured to mitigate against a thermal stress on the refuse vehicle, the thermal stress mitigation system comprising:

one or more nozzles fluidly coupled to the at least one of the container and the tank and operable to deploy the thermal stress mitigation substance.

2 . The refuse vehicle of claim 1 , wherein the thermal stress mitigation system further comprises:
a controller communicatively coupled to and configured to operate the one or more nozzles; one or more thermal sensors communicatively coupled to the controller and configured to detect the thermal stress on the refuse vehicle.

3 . The refuse vehicle of claim 2 , wherein the controller is configured to:
receive thermal stress data from the one or more thermal sensors; determine whether the thermal stress on the refuse vehicle is greater than a threshold thermal stress based on the thermal stress data; and operate the nozzles to deploy the thermal stress mitigation substance on the refuse vehicle responsive to determining that the thermal stress is greater than the threshold thermal stress.

4 . The refuse vehicle of claim 3 , further comprising at least one of an engine and a motor.

5 . The refuse vehicle of claim 4 , wherein the thermal stress mitigation system is configured to deploy the thermal stress mitigation substance on the at least one of the engine and the motor.

6 . The refuse vehicle of claim 4 , wherein the thermal stress mitigation system is positioned proximal the energy device.

7 . The refuse vehicle of claim 1 , wherein the thermal stress mitigation system is configured to deploy the thermal stress mitigation substance into the refuse compartment.

8 . The refuse vehicle of claim 1 , wherein the refuse vehicle further comprises a lift assembly, wherein the thermal stress mitigation system is configured to deploy the thermal stress mitigation substance on the lift assembly.

9 . The refuse vehicle of claim 1 , wherein the body defines a hopper, wherein the thermal stress mitigation system is configured to deploy the thermal stress mitigation substance into the hopper.

10 . A thermal stress mitigation system for a refuse vehicle, the thermal stress mitigation system comprising:
a thermal stress mitigation substance; a storage tank configured to store the thermal stress mitigation substance; one or more nozzles fluidly coupled to the storage tank and operable to deploy the thermal stress mitigation substance; a controller coupled to and configured to operate the one or more nozzles; and one or more thermal sensors coupled to the controller and configured to detect the thermal stress on the refuse vehicle.

11 . The thermal stress mitigation system of claim 10 , wherein the controller is configured to:
receive thermal stress data from the one or more thermal sensors.

12 . The thermal stress mitigation system of claim 11 , wherein the controller is configured to:
determine whether the thermal stress on the refuse vehicle is greater than a threshold thermal stress based on the thermal stress data; and operate the nozzles to deploy the thermal stress mitigation substance on the refuse vehicle responsive to determining that the thermal stress is greater than the threshold thermal stress.

13 . The thermal stress mitigation system of claim 10 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the refuse vehicle and proximal an energy device of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the energy device.

14 . The thermal stress mitigation system of claim 10 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the refuse vehicle and proximal a refuse compartment of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the refuse compartment.

15 . The thermal stress mitigation system of claim 10 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the refuse vehicle and proximal a lift assembly of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the lift assembly.

16 . An electric refuse vehicle comprising:
a chassis; a body assembly coupled to the chassis, the body assembly defining a refuse compartment; a prime mover, wherein the prime mover is an electric motor; an energy device; and a thermal stress mitigation system for a refuse vehicle, the thermal stress mitigation system comprising:
