A power conversion apparatus connected to three or more voltage units, includes three or more power conversion circuits connected to respective units of the three or more voltage units; and a multiport transformer connected to the three or more power conversion circuits at mutually different ports, in which at least one voltage unit of the three or more voltage units is an electrical load.

An electric transmission for an electric lawnmower is disclosed. The electric transmission is adapted to operatively connect to a plurality of wheels for driving the electric lawnmower over a ground surface. The electric transmission includes an electric motor and a housing encasing the electric motor. The housing includes a cylindrical body defining a chamber for receiving the electric motor, an inlet conduit, and an outlet conduit. The inlet conduit is connected to the cylindrical body and extends outwardly from the cylindrical body to facilitate a flow of air inside the chamber. The outlet conduit is disposed spaced apart from the inlet conduit. Further, the outlet conduit is connected to the cylindrical body and extends outwardly from the cylindrical body to facilitate an exit of air from the chamber to an ambient.

A refuse vehicle including a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, an electric energy system, an auxiliary power system comprising a reservoir to hold a hydraulic fluid, and a hydraulic pump powered by an electric motor, wherein the electric motor is powered by the electric energy system and the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators, and wherein a prime mover of the refuse vehicle charges the electric energy system. The one or more actuators include a packer actuator configured to compact refuse in the refuse compartment

A vehicle control system that allows a vehicle to travel easily and smoothly on a slippery road, a bumpy road, and a narrow road. A controller of the vehicle control system comprises: a running condition determiner that determines whether the vehicle travels under the particular condition; a control mode selector that selects one of vehicle speed control modes; and a driving force controller that controls a driving force such that an actual vehicle speed is adjusted to a target vehicle sped based on the selected vehicle speed control mode.

An electric drive unit for a wheel of a motor vehicle, including an electric motor for driving a drive shaft joined to the wheel in a manner resistant to rotation. The drive shaft is disposed coaxial to the rotor of the electric motor and is joined thereto in a rotation-resistant manner. The drive shaft is joined to the rotor of the electric motor in a rotation-resistant and axially moveable manner via a bearing.

A vehicle has an inverter, a motor, an output connector, and a changeover device. The inverter applies a voltage to a first output wiring line, a second output wiring line, and a third output wiring line. The motor is connected to the first output wiring line, the second output wiring line, and the third output wiring line, and drives a wheel. The output connector supplies the voltage applied to the first output wiring line, the second output wiring line, and the third output wiring line to an outside. The changeover device changes over the voltage supplied from the output connector to the outside.
