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.

Described herein relates to a system of and method for recovering energy and providing power in a multi-source transmission assembly, in which the transmission assembly includes secondary power sources in combination with a primary power source, where the secondary power sources are in reverse rotation with respect to the primary power source, such that energy is recovered during deceleration or the secondary power sources power the vehicle as needed. During the translation of a vehicle employing the transmission assembly, at least one motor may function, as needed, to propel the vehicle forward. During times in which the vehicle may not positively accelerating, at least one of the motors may switch to a generator mode to generate energy to be stored in a vehicle battery. As such, at least one of the motor power sources may recover an amount of energy expended by the vehicle during acceleration.

an electric powertrain integrated into a vehicle axle. Such electric axle (or “E-axle”) is a front or rear axle that includes an axle body (or “housing”) adapted to receive a powertrain, which is arranged to provide torque to the wheels of the axle. The “E-Axle” is a compact and economical electric drive solution for battery electric vehicles, fuel cells and hybrid applications. The electric motor(s), electronics and transmission are combined in a compact unit that directly drives the wheels provided at the longitudinal ends of the axle.
