Abstract

A refuse vehicle includes a chassis, an energy storage device, a body, and an electric power take-off system. The 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 inverter, an electric motor, and a hydraulic pump that is drive by the electric motor. The inverter receives electrical power from the energy storage device and supplies electrical power to the electric motor. The electric motor drives the hydraulic pump to convert the electrical power into hydraulic power.
