Abstract

A refuse vehicle including a chassis a body assembly coupled to the chassis, the body assembly defining a refuse compartment, an electric energy system, and an auxiliary power system comprising a reservoir to hold a hydraulic fluid, and a hydraulic pump powered by an electric motor, wherein the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators, and wherein at least one of the electric energy system or the auxiliary power system is configured to provide power to a carry can.

First claim

What is claimed is:

1. A system for a refuse vehicle, comprising:
a carry can including a grabber arm; and
an auxiliary power system including:
a hydraulic pump coupled to the carry can and configured to pressurize hydraulic fluid and provide the hydraulic fluid to one or more actuators; and
an electric motor coupled to the carry can and configured to power the hydraulic pump,
wherein the auxiliary power system is configured to provide the pressurized hydraulic fluid to the carry can.

2. The system of claim 1 , further comprising a power take-off.

3. The system of claim 1 , further comprising a cooling system configured to thermally regulate the electric motor.

4. The system of claim 1 , further including one or more electrical energy storage devices configured to power the electric motor.

5. The system of claim 4 , wherein at least one of the one or more electrical energy storage devices are removably coupled to the refuse vehicle.

6. A system for a refuse vehicle, comprising:
a tailgate; and
an auxiliary power system including:
a hydraulic pump coupled to the tailgate and configured to pressurize hydraulic fluid and provide the hydraulic fluid to one or more actuators; and
an electric motor coupled to the tailgate and configured to power the hydraulic pump;

wherein the auxiliary power system is configured to provide the pressurized hydraulic fluid to a carry can.

7. The system of claim 6 , further comprising a power take-off.

8. The system of claim 6 , further comprising a cooling system configured to thermally regulate the electric motor.

9. The system of claim 6 , further including one or more electrical energy storage devices configured to power the electric motor.

10. The system of claim 9 , wherein at least one of the one or more electrical energy storage devices are removably coupled to the refuse vehicle.

11. A refuse vehicle, comprising:
a chassis;
a body assembly coupled to the chassis, the body assembly defining a refuse compartment;
a lift assembly coupled to the chassis;
a carry can removably coupled to the lift assembly; and
an auxiliary power system including:
a hydraulic pump coupled to the carry can and configured to pressurize hydraulic fluid and provide the hydraulic fluid to one or more actuators; and
an electric motor coupled to the carry can and configured to power the hydraulic pump,

wherein the auxiliary power system is configured to provide the pressurized hydraulic fluid to the carry can.

12. The refuse vehicle of claim 11 , further comprising a power take-off.

13. The refuse vehicle of claim 11 , further comprising a cooling system configured to thermally regulate the electric motor.

14. The refuse vehicle of claim 11 , further including one or more electrical energy storage devices configured to power the electric motor.

15. The refuse vehicle of claim 14 , wherein at least one of the one or more electrical energy storage devices are removably coupled to the body assembly of the refuse vehicle.
