A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.

A drive device for a motor vehicle includes at least one electric machine and at least one shaft, which shaft is rotatably mounted on a housing element of the drive device and can be driven by the electric machine. At least one discharge ring is provided by which the shaft is brought into electrical contact with the housing element in order to dissipate electrical charges from the shaft to the housing element via the discharge ring. The discharge ring is formed from an electrically conductive fluid.

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.

Methods and systems are provided for operating a high voltage generator coupled to a plug-in hybrid vehicle driven by a reciprocating piston engine. In one example, a method may include, predicting variations in output torque from the reciprocating piston engine and adjusting the driving torque required for the high voltage electric generator based upon the predicted torque variations.

A battery pack includes an enclosure assembly, a battery assembly housed within the enclosure assembly, a mounting structure secured to the enclosure assembly, and a mounting clamp that includes a first section mounted to the mounting structure and a second section contacting the battery assembly.

The disclosure relates to an electric drive system for an aircraft and to a corresponding operating method. The electric drive system includes a multiplicity of electric thrust generators, wherein each electric thrust generator has an electric motor, and a subsystem group including a multiplicity of subsystems. The thrust generators are apportioned unambiguously between the subsystems so that each subsystem includes two or more of the thrust generators. Furthermore, a control system for operating the drive system is provided, wherein the control system is configured to operate the drive system in such a way that, at least in the event that one of the subsystems of the subsystem group is faulty, an overall yawing moment which is composed of the sum of the yawing moments of the thrust generators of each non-faulty subsystem of the subsystem group essentially disappears.

A power control system for a vehicle is disclosed. The power control system includes a first low voltage power supply, a second low voltage power supply, and an isolation switch. The first and second low voltage power supplies are capable of providing power to a plurality of subsystems. The isolation switch receives inputs from the first and second low voltage power supplies and selectively outputs power from either of the first and second low voltage power supplies to the plurality of subsystems on at least one power rail. The first low voltage power supply can be a 12-volt direct current-to-direct current (DC-DC) converter and the second low voltage power supply can be a rechargeable 12-volt battery. In case of a power failure to either of the DC-DC converter or rechargeable 12-volt battery, the isolation switch can isolate the failed power supply in the power control system and switch connection to the non-failed power supply to provide power to the subsystems.

Methods and apparatus to charge electric vehicles are disclosed. An example method includes monitoring, via a processor, a battery charge level of an electric vehicle receiving a battery charge from a mobile charging unit. The example method includes determining, via the processor, a remaining trip distance of the electric vehicle from a location of the battery charge to a trip destination. The example method further includes determining, via the processor, a target charge level for the battery charge. The target charge level corresponds to when the battery charge level provides a first probability that the electric vehicle will reach the trip destination without an additional battery charge. The example method also includes generating, via the processor, a signal to stop the battery charge when the battery charge level reaches the target charge level.
