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, an auxiliary power system comprising a reservoir to hold a hydraulic fluid, and a hydraulic pump powered by an electric motor, wherein the electric motor is powered by the electric energy system and the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators, and wherein a prime mover of the refuse vehicle charges the electric energy system.

First claim

The invention claimed is:

1. A refuse vehicle, comprising:
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 electric motor is powered by the electric energy system and the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators; and
wherein a prime mover of the refuse vehicle charges the electric energy system, and wherein at least one of the electric energy system or the auxiliary power system is configured to provide power to a carry can.

2. The refuse vehicle of claim 1 , wherein the auxiliary power system includes a power take-off.

3. The refuse vehicle of claim 1 , wherein the auxiliary power system is positioned between a cab of the refuse vehicle and the body of the refuse vehicle.

4. The refuse vehicle of claim 1 , wherein the auxiliary power system is positioned below the body of the refuse vehicle.

5. The refuse vehicle of claim 1 , wherein the auxiliary power system is mounted on a surface of the body of the refuse vehicle.

6. The refuse vehicle of claim 1 , wherein the auxiliary power system includes a cooling system configured to thermally regulate the electric motor.

7. The refuse vehicle of claim 1 , wherein the auxiliary power system includes one or more electrical energy storage devices configured to power the electric motor.

8. An auxiliary power system for a refuse vehicle, comprising:
a reservoir to hold a hydraulic fluid;
a hydraulic pump configured to pressurize the hydraulic fluid and provide the hydraulic fluid to one or more actuators;
an electric motor configured to power the hydraulic pump; and
a mounting assembly configured to couple the auxiliary power system to the refuse vehicle; and
wherein the auxiliary power system is configured to provide power to a carry can.

9. The auxiliary power system of claim 8 , wherein the mounting assembly is configured to couple the auxiliary power system between a cab of the refuse vehicle and a body of the refuse vehicle.

10. The auxiliary power system of claim 8 , wherein the mounting assembly is configured to couple the auxiliary power system below a body of the refuse vehicle.

11. The auxiliary power system of claim 8 , wherein the mounting assembly is configured to couple the auxiliary power system to a surface of the body of the refuse vehicle.

12. The auxiliary power system of claim 8 , further including a power take-off.

13. The auxiliary power system of claim 8 , further including a cooling system configured to thermally regulate the electric motor.

14. The auxiliary power system of claim 8 , further including one or more electrical energy storage devices configured to power the electric motor.

15. 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 a first electric motor; and
an auxiliary power system comprising a reservoir to hold a hydraulic fluid, and a hydraulic pump powered by a second electric motor, wherein the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators, and wherein the auxiliary power system is configured to provide power to a carry can.

16. The electric refuse vehicle of claim 15 , wherein the electric refuse vehicle includes one or more electrical energy storage devices configured to provide power to at least one of the first electric motor or the second electric motor, and wherein at least one of the one or more electrical energy storage devices are detachably coupled to the electric refuse vehicle.

17. The electric refuse vehicle of claim 15 , wherein the auxiliary power system is positioned between a cab of the electric refuse vehicle and the body of the electric refuse vehicle.

18. The electric refuse vehicle of claim 15 , wherein the auxiliary power system includes a power take-off.

19. The electric refuse vehicle of claim 15 , wherein the auxiliary power system is positioned on a surface of the body of the electric refuse vehicle.

20. The electric refuse vehicle of claim 15 , wherein the auxiliary power system is positioned below the body of the electric refuse vehicle.
