A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. The energy storage device 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 vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.

Electric power take-off pump control system

A refuse vehicle includes a battery configured to provide electrical energy to drive at least one of a plurality of wheels, a vehicle body supported by the chassis and defining a receptacle for storing refuse therein, and an electric power take-off system including a motor configured to power to a hydraulic system in response to receiving the electrical energy from the battery, an inverter configured to provide the electrical energy to the motor from the battery, a sensor configured to detect thermal energy within the inverter, and a controller configured to receive data from the sensor, wherein the controller is further configured to determine if the data from the sensor is greater than a critical operating condition and reduce a rate of electrical energy supplied to the motor in response to determining that the data from the sensor is greater than the critical operating condition.

System and method for electronic power take-off controls

A refuse vehicle includes a chassis, an energy storage device, a body, a first electric power take-off system, and a second electric power take-off system. The energy storage device 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 supported by the chassis. The first electric power take-off system is coupled to at least one of the body and the chassis, and includes a first motor that is configured to drive a first hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. The second electric power take-off system is coupled to at least one of the body and the chassis, and includes a second motor that is configured to drive a second hydraulic pump to convert electrical power received from the energy storage device into hydraulic power.

Control system for a refuse vehicle

A refuse vehicle includes a chassis, an energy storage device, a body, an electric power take-off system, and a disconnect. The energy storage device 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 supported by the chassis and defines a receptacle for storing refuse. The electric power take-off system is positioned on the refuse vehicle, and includes a motor that is configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. The disconnect is positioned between the energy storage device and the electric power take-off system and is configured to selectively decouple the electric power take-off system from the energy storage device.

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.

A refuse vehicle includes a chassis, a battery, a vehicle body, an electric power take-off system, and a lifting system. 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 electric power take-off system is positioned within the receptacle. 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.
