A rotatable drive axle assembly for an electric vehicle comprises a rotatable vehicle drive axle configured to be disposed along a transverse axis of an electric vehicle and having an axle end that is configured for attachment of a drive wheel. The rotatable drive axle assembly also comprises a selectively movable differential configured to be disposed on the rotatable vehicle drive axle and configured to operatively couple motive power of a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis to the rotatable vehicle drive axle and the drive wheel, the selectively movable electric propulsion motor and the motor axis configured to be oriented in a substantially vertical direction and movable with reference to the rotatable vehicle drive axle.

An agricultural implement is provided. The agricultural implement includes an energy storage system configured to provide power to an electrical system of the agricultural implement. The agricultural implement also includes a regenerative braking system configured to slow or stop the agricultural implement and to provide power to the energy storage system.

A liquid-cooled electric drive system for a motor vehicle and a method of operating the drive system.

A single-wheeled balance vehicle comprises a motor, pedals, a wheel, a power module and a control module. The motor comprises a motor housing and a spindle. The power module and the control module are fixed to the spindle. The power module comprises at least one power unit. The control module comprises a first control unit electrically connected to the power unit and the motor. The two ends of the spindle are fixedly connected to the pedals respectively. The wheel is of a hollow structure having two ends formed with openings, is arranged on the motor housing in a sleeving manner and is fixedly connected to the motor housing. The power module and the control module are located in the wheel. Miniaturization of the single-wheeled balance vehicle is facilitated, and the service life of the single-wheeled balance vehicle is prolonged.

A motor vehicle with at least one energizable active current line, which at least sometimes carries an active current for the operation of at least one electrical consumer. At least one attenuation line layout is coupled by way of an inductive coupling to the energizable active current line in such a way that, in a protection area spaced apart from the active current line and the attenuation line layout, a magnetic field generated by the active current and/or a perturbation superimposed on the active current and/or a leakage current produced by the active current is attenuated by current flow induced in the attenuation line layout.

A device for transporting a payload (to include a human user) over varied terrain. A platform accommodates the payload. A pair of wheel clusters are mounted to opposite ends of the platform and are powered in rotation relative thereto. Each includes at least two co-planar wheels powered by electric motors. A latch is hand-operable (without tools) to secure the cluster to the platform and, alternatively, allow the cluster to be detached from the platform and rotated 90 to lie parallel thereto. An electrical connector conducts electric power from the platform to the cluster when the latch is operated/actuated to secure the cluster to the platform, and is configured such that it does not impede or obstruct detaching the wheel cluster from the platform, with no requirement that the user take any additional step (other than actuating the latch) to detach the wheel cluster.

A control method may include: controlling a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a first leg, and a second leg set to turn on or off, to form in a first period a circuit loop for a charge/discharge module to discharge to a motor and to form in a second period a circuit loop for the charge/discharge module and the motor to charge a first electric vehicle battery group and a second electric vehicle battery group or form in the second period a circuit loop for the motor to charge the first electric vehicle battery group and the second electric vehicle battery group.

In a process of cancelling shutdown of a second converter during transmission of electric power between a first power line and a second power line with voltage conversion by a first converter in a shutdown state of the second converter, a motor vehicle performs single element switching control that switches one switching element between third and fourth switching elements of the second converter while setting the other switching element off, such as to prevent an electric current in a reverse direction to an electric current flowing in a first reactor of the first converter from flowing in a second reactor of the second converter.
