A battery system including a removable battery pack, including a plurality of battery cells and an interface for electrically and mechanically coupling to a load bearing device; a vehicle, including a power station for providing power to drive the vehicle, the power station including a port for accepting the removable battery pack; and a power tool including a port for accepting the removable battery pack.

A method is provided. An airship is maneuvered to a desired location and oriented with the thruster such that ambient wind is traveling in a direction that is substantially parallel to the longitudinal axis of the fuselage. The airflow from the ambient wind is straightened with the flow straightener to generate a substantially laminar flow. The turbine is engaged with the airflow generated by the ambient wind to generate electricity, and the electricity generated by the turbine is rectified with the rectifier and stored in the storage array.

A method for orienting a power receiving coil of a vehicle relative to a power emitting coil of a wireless charging system for a vehicle. The method includes detecting a positioning of the vehicle at a charging location in which the power receiving coil detects reception of electromagnetic radiation emitted from the power emitting coil, performing a calibration sequence in which the orientation of the power receiving coil and/or the power emitting coil is varied according to a predetermined scheme, while registering the electromagnetic radiation reception of the power receiving coil, in response to the calibrations sequence, determining a desired relative orientation including relative angle between the power receiving coil and the power emitting coil for which the electromagnetic radiation reception of the power receiving coil is in a top range of the registered electromagnetic radiation reception.

A charging apparatus for charging a battery of an electrically operable vehicle includes a plug element, a base element, and adjusting facility. The plug element is connectable to a corresponding, vehicle-side plug element of the motor vehicle and via which electrical energy is transferrable to the motor vehicle so as to charge the battery. The base element is connected to a current source and provides electrical energy from the current source for the plug element. Via the adjusting facility the plug element is movable relative to the base element in order to connect the plug element to the vehicle-side plug element, and via which an electrical connection is provided between the base element and the plug element. The adjusting facility has an overload protection via which the base element is electrically separated from the plug element in the event of a predetermined mechanical maximal load being exceeded.

The invention refers to a plug-in module for charging of batteries in an electronic device, comprising a pad-element configured to receive wireless input of electromagnetic energy; a chassis connected with the pad-element and provided with a plug connector which is configured to be plugged in a charging socket of the electronic device wherein the chassis comprises integrated energy transmission channels and a circuit board configured to transfer and convert the electromagnetic energy from the pad-element into a charging current provided at the plug connector.

In an embodiment, an apparatus for charging an electric vehicle, can include a receptacle mountable to a structure above the electric vehicle. The receptacle can maintain a charge transmitting device, which can be automatically moveable and directable from the receptacle toward a target area on the electric vehicle associated with a receiving coil mounted on the electric vehicle for the charging of an electric vehicle when the one receiving coil engages with the charge transmitting device when the electric vehicle is located below the receptacle. One or more optical sensors can be utilized to direct the charge transmitting device toward the target.

An attachment module constructed to enable a vehicle charging robot to attach to a vehicle and to thereafter insert its charging connector into the vehicle's charging socket. Once the vehicle is charged and the charging connector is disconnected from the charging socket, the attachment module is further constructed to enable the robot to detach from the vehicle.
