  • Patent number: 12084276
    Abstract: 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.

  • Patent number: 12077375
    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.

  • Publication number: 20240286831
    Abstract: 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.
