Abstract

A refuse vehicle includes a chassis, a first energy storage device, a body, an electric power take-off system, and a subsystem coupled to the body and moveable using hydraulic power from the electric power take-off system. The first energy storage device (e.g., a battery) is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The body is configured for storing refuse, and is supported by the chassis. The electric power take-off system is positioned on the body and includes an electric motor, a second energy storage device configured to provide electric power to the electric motor, and a hydraulic pump that is drive by the electric motor. The electric motor drives the hydraulic pump to convert the electrical power into hydraulic power.

First claim

What is claimed is:

1. A refuse vehicle comprising:
a chassis;
a first energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the refuse vehicle;
a body for storing refuse therein supported by the chassis;
an electric power take-off system positioned on the body, the electric power take-off system including an electric motor, a second energy storage device configured to provide electric power to the electric motor, and a hydraulic pump driven by the electric motor, wherein the electric motor drives the hydraulic pump to convert the electrical power into hydraulic power; and
a subsystem coupled to the body and moveable using hydraulic power from the electric power take-off system,
wherein each of the electric motor, the second energy storage device, and the hydraulic pump are positioned within a housing, and
wherein a thermal management system is received within the housing and configured to provide cooling air into the housing.

2. The refuse vehicle of claim 1 , wherein the housing is positioned on the body.

3. The refuse vehicle of claim 1 , wherein the body defines a receptacle for receiving and storing the refuse, and wherein the housing is formed within the receptacle.

4. The refuse vehicle of claim 1 , wherein the electric power take-off system further comprises an inverter, and wherein the inverter receives electrical power from the first energy storage device and supplies electrical power to the electric motor.

5. The refuse vehicle of claim 4 , wherein a disconnect is positioned between the first energy storage device and the electric power take-off system and configured to selectively decouple the electric motor from the first energy storage device.

6. The refuse vehicle of claim 4 , wherein the inverter is positioned within the housing.

7. The refuse vehicle of claim 1 , wherein the thermal management system includes a fan.

8. The refuse vehicle of claim 1 , wherein the thermal management system includes a radiator.

9. A vehicle comprising:
a chassis;
an energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the vehicle;
a body for storing refuse therein supported by the chassis;
an electric power take-off system positioned on the body, the electric power take-off system including an electric motor and a hydraulic pump driven by the electric motor, wherein the electric motor drives the hydraulic pump to convert the electrical power into hydraulic power; and
a disconnect electrically coupled between the energy storage device and the electric power take-off system, wherein the disconnect is configured to selectively decouple the electric motor from the energy storage device,
wherein the electric motor and the hydraulic pump are positioned within a housing coupled to the body, and wherein the disconnect is positioned outside the housing, and
wherein a thermal management system is received within the housing and configured to facilitate heat transfer from the housing.

10. The vehicle of claim 9 , wherein the housing is positioned within a refuse receptacle of the body.

11. The vehicle of claim 9 , wherein the housing is a cabinet housing positioned along the body.

12. The vehicle of claim 9 , wherein the electric power take-off system further comprises an inverter, wherein the inverter is received within the housing.

13. A refuse vehicle comprising:
a chassis;
an energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the refuse vehicle;
a body for storing refuse therein supported by the chassis;
an electric power take-off system positioned on the body, the electric power take-off system including an electric motor and a hydraulic pump driven by the electric motor, wherein the electric motor drives the hydraulic pump to convert electrical power received from the energy storage device into hydraulic power; and
a subsystem coupled to the body and moveable using hydraulic power from the electric power take-off system,
wherein at least one of the electric motor or the hydraulic pump is positioned within a cabinet housing formed alongside the body, and the other of the at least one of the electric motor or the hydraulic pump is positioned within a body housing positioned on the body, and
wherein a thermal management system is received within at least one of the cabinet housing or the body housing and configured to provide cooling air into the at least one of the cabinet housing or the body housing.

14. The refuse vehicle of claim 13 , wherein the electric power take-off system further comprises an inverter, wherein the inverter is received within one of the cabinet housing or the body housing.

15. The refuse vehicle of claim 13 , wherein a disconnect is electrically coupled between the energy storage device and the electric power take-off system, wherein the disconnect is configured to electrically decouple the energy storage device from the electric power take-off system.

16. The refuse vehicle of claim 13 , wherein the body housing is positioned within a refuse receptacle of the body.
