Abstract

A modular electric power take-off (E-PTO) system for a refuse vehicle includes a modular housing. The modular E-PTO also includes a motor, an inverter, a battery, and a hydraulic pump positioned within the modular housing. The modular housing is removably coupled with a front of a waste receptacle or a hopper of the waste receptacle of a refuse vehicle.

First claim

What is claimed is:

1. A refuse vehicle comprising:
a chassis supporting a plurality of tractive elements;
a chassis battery supported by the chassis and configured to provide electrical power to a first motor, wherein rotation of the first motor selectively drives at least one of the plurality of tractive elements;
a vehicle body supported by the chassis and defining a receptacle for storing refuse therein; and
a modular electric power take-off (“E-PTO”) system comprising a plurality of components positioned within a modular housing that is removably coupled with the vehicle body, the plurality of components of the modular E-PTO system comprising a motor, an inverter, a battery, and a hydraulic pump;
wherein a plurality of high voltage (“HV”) components of the modular E-PTO system are electrically accessible to be electrically coupled with a HV electrical system of the refuse vehicle at a single connection point provided at a junction plate of the modular E-PTO system or at a junction box.

2. The refuse vehicle of claim 1 , where the modular E-PTO system is removably coupled with a front of the receptacle or a hopper of the receptacle.

3. The refuse vehicle of claim 2 , wherein the modular E-PTO system is fastened to a pair of brackets on a front of the hopper of the receptacle, the pair of brackets protruding from a front wall of the hopper at opposite lateral ends of the hopper.

4. The refuse vehicle of claim 1 , wherein the motor of the modular E-PTO system is configured to consume electrical energy from the battery through the inverter and drive the hydraulic pump to provide pressurized hydraulic fluid to one or more hydraulic systems of the refuse vehicle to perform an operation.

5. The refuse vehicle of claim 1 , wherein the modular E-PTO system is configured to be removed from the refuse vehicle as a unit by electrically de-coupling the HV components of the modular E-PTO system from the HV electrical system of the refuse vehicle at the single connection point, de-coupling one or more hydraulic lines, and removing the modular housing.

6. The refuse vehicle of claim 1 , wherein the modular housing is proximate a cabin of the refuse vehicle, the cabin positioned forwards of the receptacle.

7. The refuse vehicle of claim 1 , further comprising a switch electrically coupled with the single connection point, wherein the switch is transitionable between an on position such that the HV components of the modular E-PTO system exchange energy with the HV electrical system of the refuse vehicle, and an off position such that the HV components of the modular E-PTO system are limited from exchanging energy with the HV electrical system of the refuse vehicle for removal or installation of the modular E-PTO system.

8. The refuse vehicle of claim 1 , wherein the junction plate is coupled with and defines part of a sidewall of the modular housing.

9. The refuse vehicle of claim 1 , wherein the junction box is positioned within the modular housing and comprises a pair of connectors on different sides of the junction box and a pair of cables forming a 90 degree turn within the junction box and electrically coupling the pair of connectors on the different sides of the junction box.

10. A modular electric power take-off (E-PTO) system for a refuse vehicle, the modular E-PTO system comprising:
a modular housing; and
a motor, an inverter, a battery, and a hydraulic pump positioned within the modular housing;
wherein the modular housing is removably coupled with a front of a waste receptacle or a hopper of the waste receptacle of a refuse vehicle.

11. The modular E-PTO system of claim 10 , wherein a plurality of high voltage (“HV”) components of the modular E-PTO system are electrically accessible to be electrically coupled with a HV electrical system of the refuse vehicle at a single connection point provided at a junction plate of the modular E-PTO system or at a junction box.

12. The modular E-PTO system of claim 11 , wherein the modular E-PTO system is configured to be removed from the refuse vehicle as a unit by electrically de-coupling the HV components of the modular E-PTO system from the HV electrical system of the refuse vehicle at the single connection point, de-coupling one or more hydraulic lines, and removing the modular housing.

13. The modular E-PTO system of claim 11 , further comprising a switch electrically coupled with the single connection point, wherein the switch is transitionable between an on position such that the HV components of the modular E-PTO system exchange energy with the HV electrical system of the refuse vehicle, and an off position such that the HV components of the modular E-PTO system are limited from exchanging energy with the HV electrical system of the refuse vehicle for removal or installation of the modular E-PTO system.

14. The modular E-PTO system of claim 11 , wherein the junction plate is coupled with and defines part of a sidewall of the modular housing.

15. The modular E-PTO system of claim 11 , wherein the junction box is positioned within the modular housing and comprises a pair of connectors on different sides of the junction box and a pair of cables forming a 90 degree turn within the junction box and electrically coupling the pair of connectors on the different sides of the junction box.

16. The modular E-PTO system of claim 10 , wherein the modular housing is fastened to a pair of brackets on a front of the hopper of the waste receptacle, the pair of brackets protruding from a front wall of the hopper at opposite lateral ends of the hopper.

17. The modular E-PTO system of claim 10 , wherein the motor of the modular E-PTO system is configured to consume electrical energy from the battery through the inverter and drive the hydraulic pump to provide pressurized hydraulic fluid to one or more hydraulic systems of the refuse vehicle to perform an operation.

18. The modular E-PTO system of claim 10 , wherein the modular housing is proximate a cabin of the refuse vehicle, the cabin positioned forwards of the waste receptacle.

19. A refuse vehicle comprising:
a chassis coupled with a plurality of wheels;
a chassis battery supported by the chassis and configured to provide electrical power to a first motor, wherein rotation of the first motor selectively drives at least one of the plurality of wheels;
a vehicle body supported by the chassis and defining a receptacle for storing refuse therein; and
a modular tailgate assembly comprising a tailgate pivotally coupled with the vehicle body, and a plurality of electric actuators;
wherein a plurality of high voltage (“HV”) components of the modular tailgate assembly are electrically accessible to be electrically coupled with a HV electrical system of the refuse vehicle at a single connection point provided at a junction plate of the modular tailgate assembly or at a junction box.

20. The refuse vehicle of claim 19 , wherein the modular tailgate assembly is electrically de-couplable at the single connection point from the HV electrical system of the refuse vehicle for physical removal of the modular tailgate assembly from the vehicle body.
