A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.

For this purpose, an electric motor and a multistage transmission which is arranged downstream of the electric motor are provided as drive elements for acting on an actuating element, and a drive housing which houses drive elements is also provided. The actuating element is a locking element of the locking device for example. The drive housing is equipped with inner and/or edge-side protrusions. The protrusions have direct bearing points for individual drive elements or all of the drive elements.

A method for controlling a charge transfer of an electric vehicle using an electric vehicle charging station, a mobile device, and a cloud server is disclosed. The method includes: receiving, at a mobile device, a message for an electric vehicle of a user from the electric vehicle charging station, wherein a user of the mobile device is associated with the electric vehicle to be charged; sending, from the mobile device, the message for the electric vehicle of the user to the cloud server, wherein the charge transfer request relayed from the mobile device includes identification information; in response to a charging control signal being authorized using identification information received from the mobile device, receiving the charging control signal from the cloud server at the mobile device to be forwarded to the electric vehicle charging station, wherein the charging control signal is configured to adjust a charging parameter at the electric vehicle charging station.

An electric vehicle charging method includes at a user terminal, transmitting a location information of the user terminal to a management sever; at the management sever, determining at least one usable charging device corresponding to the location information; at the management sever, transmitting information for at least one determined charging device to the user terminal; at the user terminal, choosing at least one charging device among the at least one determined charging device; at the user terminal, transmitting a preemption request information for preemption at least one chosen charging device to the management server; at the management sever, locking at least one charging device corresponding to the preemption request information by transmitting a preemption order signal; at the management sever, transmitting information for a user of the user terminal to locked charging device; and unlocking the charging device corresponding to inputting a authentication information for authentication of the user.

An onboard battery charging system including battery system and battery controller protection mechanisms and providing battery charge optimization where the protection portions of the system use an input isolation mechanism to isolate the vehicle power input from the battery controller upon detection of deviant charge voltages and a battery isolation mechanism to isolate the battery controller from the batteries upon detection of cyberattacks resulting in deviant charge power being provided to the batteries and where the charge optimization portions of the system use the same input isolation mechanisms as are employed for the vehicle system protection input isolation to regulate the timing of vehicle charging as a function of electricity prices.

Submitted is an abnormality detection device including a processing unit, and a communication unit that can communicate with a ground electric power supply device that transmits electric power to a vehicle in a non-contact manner. The processing unit is configured to detect electricity theft or electricity leakage in the ground electric power supply device, based on a time dependent change pattern of an electric power supply amount of the ground electric power supply device or a parameter that is correlated to the electric power supply amount, the time dependent change pattern being a time dependent change mode.

A server includes: a communicator configured to communicate with a plurality of ground power supply devices configured to transmit electric power to a vehicle in a non-contact manner; a storage configured to store at least information on a total power supply amount within a predetermined period of the ground power supply devices; and one or more processors configured to, when a total power supply amount within a predetermined period of one ground power supply device among the ground power supply devices is equal to or greater than a determination threshold value set based on data of the total power supply amount within the predetermined period of the ground power supply devices, determine that stealing or leakage of electricity has occurred in the one ground power supply device.

An electric aircraft charging connector, including a set of pins, a sensor, a controller, and a locking mechanism. The set of pins may include an AC pin, the AC pin configured to supply AC power to a charging port and/or a DC pin, the DC pin configured to supply DC power to the charging port. The sensor can detect power flow from the pins to the charging port. The controller is communicatively connected to the sensor and configured to receive a signal from the sensor and send a locking signal to a locking mechanism. The locking mechanism is communicatively connected to the controller, having an engaged state wherein the charging connector is mechanically coupled to the charging port and a disengaged state wherein the charging connector is mechanically uncoupled form the charging port, the locking mechanism configured to receive a locking signal from the controller and enter the engaged state.

A locking device for an electrical charging device of a motor vehicle, in particular an electric or hybrid vehicle. The locking device is equipped with a movable bolt element, which is provided for releasably locking a charging plug in a charging socket of the electrical charging device. In addition, the movable bolt element can be moved at least into the positions “unlocked” and “locked.” Furthermore, a motor-driven drive is realized, which is provided for moving the bolt element. According to the invention, the bolt element can be moved into a third “self-locked” position beyond the “locked” position, which can be reached by means of the drive and in which unlocking is impossible without the drive.
