Control system for a refuse vehicle
A refuse vehicle includes a chassis, a battery, a vehicle body, an electric power take-off system, a lifting system, and a disconnect. The chassis supports a plurality of wheels. The battery is supported by the chassis and is configured to provide electrical power to a first motor. Rotation of the first motor selectively drives at least one of the plurality of wheels. The vehicle body is supported by the chassis and defines a receptacle for storing refuse. The electric power take-off system is coupled to the vehicle body and includes a second motor configured to convert electrical power received from the battery into hydraulic power. The lifting system is coupled to the vehicle body and is movable relative to the receptacle using hydraulic power from the electric power take-off system. The disconnect is positioned between the battery and the electric power take-off and is configured to selectively decouple the electric power take-off system from the battery.

2. The refuse vehicle of claim 1 , wherein the hydraulic pump provides hydraulic fluid to a hydraulic cylinder within the lifting system to move the lifting system relative to the receptacle in response to rotation by the second motor.
3. The refuse vehicle of claim 2 , wherein when the disconnect decouples the electric power take-off system from the battery, the second motor is decoupled from the battery and the hydraulic pump is disabled.
4. The refuse vehicle of claim 2 , wherein the electric power take-off system provides pressurized hydraulic fluid to a second hydraulic cylinder, wherein the second hydraulic cylinder operates a compactor within the receptacle.
5. The refuse vehicle of claim 2 , wherein the disconnect is an electric power control box having a housing, wherein the housing defines a waterproof cavity having a positive terminal bus and a negative terminal bus received therein.
6. The refuse vehicle of claim 5 , wherein the positive terminal bus receives a first positive cable extending away from the battery and a second positive cable extending away from the electric power take-off system.
7. The refuse vehicle of claim 6 , wherein the negative terminal bus receives a first negative cable extending away from the battery and a second negative cable extending away from the electric power take-off system.
8. The refuse vehicle of claim 7 , wherein the positive terminal bus includes a manual switch, the manual switch movable between a first position and a second position, wherein in the first position, the first positive cable is electrically coupled to the second positive cable, and wherein in the second position, the first positive cable is electrically decoupled from the second positive cable.
9. The refuse vehicle of claim 8 , wherein the electric power take-off system further comprises an inverter, wherein the inverter is configured to transform direct current from the battery into alternating current to supply to the second motor.
10. A refuse vehicle comprising:
a chassis supporting a plurality of wheels;
a 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;
an electric power take-off system coupled to the vehicle body, the electric power-take-off system including a second motor configured to convert electrical power received from the battery into hydraulic power;
a compactor positioned within the receptacle and movable relative to the receptacle using hydraulic power from the electric power take-off system; and
a disconnect positioned between the battery and the electric power take-off and configured to selectively decouple the electric power take-off system from the battery.
11. The refuse vehicle of claim 10 , wherein the electric power take-off system includes the second motor and a hydraulic pump, wherein the hydraulic pump provides hydraulic fluid to a hydraulic cylinder within the compactor to move the compactor relative to the receptacle.
12. The refuse vehicle of claim 11 , wherein when the disconnect decouples the electric power take-off system from the battery, the second motor is decoupled from the battery and the hydraulic pump is disabled.
13. The refuse vehicle of claim 11 , wherein the electric power take-off system provides pressurized hydraulic fluid to a second hydraulic cylinder, wherein the second hydraulic cylinder operates a lifting system, wherein the lifting system is coupled to the vehicle body and movable relative to the receptacle when pressurized hydraulic fluid is provided to the second hydraulic cylinder.
14. The refuse vehicle of claim 11 , wherein the disconnect is an electric power control box having a housing, wherein the housing defines a waterproof cavity having a positive terminal bus and a negative terminal bus received therein.
15. The refuse vehicle of claim 14 , wherein the positive terminal bus receives a first positive cable extending away from the battery and a second positive cable extending away from the electric power take-off system.
16. The refuse vehicle of claim 15 , wherein the negative terminal bus receives a first negative cable extending away from the battery and a second negative cable extending away from the electric power take-off system.
17. The refuse vehicle of claim 16 , wherein the positive terminal bus includes a manual switch, the manual switch movable between a first position and a second position, wherein in the first position, the first positive cable is electrically coupled to the second positive cable, and wherein in the second position, the first positive cable is electrically decoupled from the second positive cable.
18. The refuse vehicle of claim 10 , wherein the electric power take-off system further comprises an inverter, wherein the inverter is configured to transform direct current from the battery into alternating current to supply to the second motor.
19. A refuse vehicle comprising:
a chassis supporting a plurality of wheels;
a 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;
an electric power take-off system coupled to the vehicle body, the electric power-take-off system including a second motor configured to convert electrical power received from the battery into hydraulic power;
a lifting system coupled to the vehicle body and movable relative to the receptacle using hydraulic power from the electric power take-off system;
a compactor positioned within the receptacle and movable relative to the receptacle using hydraulic power from the electric power take-off system; and
a disconnect positioned between the battery and the electric power take-off and configured to selectively decouple the electric power take-off system from the battery to disable the lifting system and the compactor.
