A method for operating an electric vehicle, in which an automatic unlocking function for a vehicle-side charging interface is activated if it is established on the basis of an ascertained position of the electric vehicle that the electric vehicle is arranged at a public charging column. The activated automatic unlocking function effectuates automatic unlocking of the charging interface as soon as a charging procedure of the electric vehicle is ended and thus a charging cable connected to the vehicle-side charging inter-face is released. The invention furthermore relates to a control device for an electric vehicle.

A vehicle system includes a processing device programmed to monitor a vehicle battery, predict a vehicle maneuver, and determine whether the vehicle battery has sufficient charge for a vehicle to execute the predicted maneuver. The processing device is further programmed to perform a preparatory action if the vehicle battery lacks sufficient charge for the vehicle to execute the predicted maneuver.

To protect a charging station LS against improper use, a second identification feature ID2 is also checked in addition to a first identification feature ID 1. The charging process is only authorized or continued if the check of the second identification feature ID2 was also successful. The authentication or authorization is thus implemented in a low-threshold manner by means of an additional authentication, in which a weak identification is supplemented by one or more further automatic identifications, which can also be checked continuously. This means that an authorized and genuine user does not incur any additional expense, while at the same time any damage caused by behavior in breach of contract by authorized users can be greatly reduced. Related system and methods for protecting against unauthorized use are also disclosed.

A charging unit guidance system includes a processor and a memory. The memory includes instructions that upon execution by the processor, cause the processor to receive a sequence of user states associated with a user of a first autonomous vehicle, each user state being one of a walking state and an at-charging-unit state and the sequence of user states being based on a sequence of observed user speeds associated with detected user position data associated with movement of the user from the first autonomous vehicle to a charging unit and at the charging unit, determine a charging unit location of the charging unit based on a correlation between the at-charging-unit states in the sequence of user states and the user position data, and upload the charging unit location associated with the charging unit to an edge computing system, the edge computing system being configured to provide guidance instructions to the charging unit to a second autonomous vehicle based at least in part on the charging unit location.

A data transmitting device includes: a transmitter; a processor; and a memory comprising instructions that, when executed by the processor, cause the processor to perform operations. The operations include: performing beam forming processing with a terminal provided in at least one moving object; detecting a beam angle based on a result of the beam forming processing; estimating a position of the at least one moving object based on the beam angle and installation position information of the data transmitting device; determining whether the estimated position of the at least one moving object is within a communication area of the data transmitting device; and transmitting desired data to the at least one moving object through the transmitter if it is determined to be within the communication area.

Systems, methods, and non-transitory computer-readable media can determine a trajectory for a vehicle, the trajectory associated with a predicted path to be traveled by the vehicle. A power optimization plan is generated for the vehicle based on the trajectory. One or more power management settings are modified based on the power optimization plan.

A network-controlled charge transfer device for electric vehicles includes a control device to turn electric supply on and off to enable and disable charge transfer for electric vehicles, a transceiver to communicate requests for charge transfer with a remote server and receive communications from the remote server, and a controller, coupled with the control device and the transceiver, to cause the control device to turn the electric supply on based on communication from the remote server.

An energy storage robot configured to be used to power electric underground equipment, the energy storage robot including a propulsion system being arranged to move the energy storage robot, an energy storage unit, a control unit being connected to the propulsion system and the energy storage unit. The energy storage unit is connectable to the electric underground equipment for powering the electric underground equipment and the control unit is arranged to communicate a level of energy of the energy storage unit to a coordinating module or another energy storage robot.

A server of a network-controlled charging system for electric vehicles receives a request for charge transfer for an electric vehicle at a network-controlled charge transfer device, determines whether to enable charge transfer, and responsive to determining to enable charge transfer, transmits a communication to the network-controlled charge transfer device that indicates to the network-controlled charge transfer device to enable charge transfer.

A network-controlled charge transfer device for electric vehicles includes a control device to turn electric supply on and off to enable and disable charge transfer for electric vehicles, a transceiver to communicate requests for charge transfer with a remote server and receive communications from the remote server, and a controller, coupled with the control device and the transceiver, to cause the control device to turn the electric supply on based on communication from the remote server.
