The invention relates to a method for inductive energy transmission from a transmitting coil to a receiving coil spaced apart from the transmitting coil. The receiving coil is arranged in a vehicle which is arranged stationary or is travelling on a supporting surface, wherein the vehicle has at least one sensor. In a first method step (A) a distance between the transmitting coil and/or the supporting surface and the receiving coil is determined, in a second method step (B) a minimum possible air gap between the transmitting coil and/or the supporting surface and the receiving coil is calculated from the distance, and in a third method step (C) the receiving coil is positioned such that the distance corresponds to the minimum possible air gap.

A system and method for managing vehicle charging stations such that when at least two of a plurality of electric vehicle charging stations (also known as electric vehicle service equipment, or EVSE) occupied with vehicles awaiting a charge, the present system manages the charging of individual vehicles in cases where the aggregated demand for charging exceeds the capacity of the circuits supplying the plurality of EVSE. By cycling so that only a few of the vehicles are charging at a time, the demand on the circuits is kept below a predetermined limit. In cases where a load shedding event is in progress, the limit can be further reduced. In cases where the cost of electricity is varying dynamically, the system considers a driver's explicit charging requirements (if any) and preferences for opportunistic charging when the price of electricity is not too high.

A transport trolley for consignments having wheels which define a contact plane for moving the trolley, having a load compartment for receiving consignments during transport, and having a shelf for carrying consignments. The shelf can be adjusted from a lower non-use position arranged in the load compartment into an upper, moderate use position arranged outside the load compartment, and back. The shelf can be adjusted from a lower non-use position arranged in the load compartment into an upper, elevated use position arranged outside the load compartment, and back. The moderate use position and the elevated use position are arranged in a range between 1.0 m and 1.7 m above the contact plane. The elevated use position is arranged above the moderate use position, and a drive is provided for at least partially adjusting the height of the shelf above the contact plane.

The present disclosure relates to a horizontal composite electricity supply structure, which comprises a first insulation layer, a second insulation layer, two electrically conductive layers, and a plurality of electrochemical system element groups. The two electrically conductive layers are disposed on the first and second insulation layers, respectively. The electrochemical system element groups are disposed between the first insulation layer and the second insulation layer, and connected in series and/or in parallel via the electrically conductive layers. The electrochemical system element group is formed by several serially connected electrochemical system elements. Each electrochemical system element includes a package layer on the sidewall, so that their electrolyte systems do not circulate with one another. Thereby, the high voltage produced by connection will not influence any single electrochemical system element nor decompose their respective electrolyte systems. Hence, serial and/or parallel connections are made concurrently in the horizontal composite electricity supply structure.

A mobility unit may include a driving portion connected to a driveshaft of a vehicle for providing driving force to the vehicle, a rear glass portion provided at a rear portion of the vehicle to be operable to isolate the rear portion of the vehicle, a front connection portion or a rear connection portion provided at the front or at the rear of the vehicle to be fastened to another vehicle, and an integrated controller for controlling the operation of the front connection portion or the rear connection portion depending on the direction in which the vehicle is coupled to another vehicle and controlling the operation of the rear glass portion and the driving portion when the vehicle is coupled to another vehicle.

A current limiting method of a fuel cell stack is capable of preventing current of the fuel cell stack from rapidly dropping to prevent jerking or shock from occurring while a vehicle travels. The method includes: determining whether performance deterioration of a unit cell of the fuel cell stack has occurred, employing a feed forward control type current limiting logic of the fuel cell stack before an output of the fuel cell vehicle is lowered, decreasing the current of the fuel cell stack to a predetermined level by the feed forward control type current limiting logic, and gradually restoring the current of the fuel cell stack to a maximum current usage value from a point in time when the current of a load is used.

A battery pack is provided. The battery pack includes a battery cell assembly including at least a battery cell, a heat dissipation member, and a plate member; and an exterior case. The heat dissipation member and the plate member are disposed in this order on one or both of an electrode of the battery cell and a side surface of the battery cell along a direction in which the battery cell assembly is assembled in the exterior case.

An electric vehicle charger includes a power supply and a controller. The power supply is for supplying electric power over a charging connection to an electric vehicle. The charging connection employs charging conductors to supply electric power from the power supply to the electric vehicle for charging. The power supply is adapted to send data to and receive data from the electric vehicle over the charging conductors according to a power-line communications protocol. The controller coupled to the power supply to control supply of electric power to the electric vehicle, The controller is adapted to, prior to initiating supply of electric power by the power supply to the electric vehicle for charging, communicate with the electric vehicle to identify a payment method associated with the electric vehicle and with the payment network to authorize the payment method for payment for electric power supplied to the electric vehicle for charging.

A vehicle control apparatus includes a battery remaining-amount recognizing unit recognizing a remaining amount of a battery and a distance measurement control unit measuring a vehicle-terminal distance by switching, based on the remaining amount of the battery recognized by the battery remaining-amount recognizing unit, between a first distance measurement mode repeatedly measuring the vehicle-terminal distance by a distance measuring unit without depending on reception of measurement instruction information transmitted from a mobile terminal and a second distance measurement mode measuring the vehicle-terminal distance by the distance measuring unit in response to reception of the measurement instruction information transmitted from the mobile terminal when communication is established between the vehicle communication control unit and the mobile terminal.
