Publication number: 20240409309Abstract: 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.Type: ApplicationFiled: August 19, 2024Publication date: December 12, 2024Applicant: Oshkosh CorporationInventors: Jeffrey Koga, Emily Davis, Jerrod Kappers, Vince Schad, Robert S.
