The present invention presents a method providing an additional service during electric vehicle charging by (a) the electric vehicle charger (200) detecting connection with an electric vehicle (100) via a charging cable; (b) the electric vehicle charger (200) exchanging charging messages through a charging port in a PLC modem, when the connection is detected in step (a); and (c) the electric vehicle charger (200) providing an additional service for the electric vehicle once the charging begins, and therefore, providing additional services such as software updates, vehicle contents updates requested by a driver during the charging of the electric vehicle, and thus providing convenience for the car owners without visiting car diagnostic service center.

A computer implemented method for managing charge availability of a charge unit (CU) to obtain charge for a battery of an electric vehicle (EV) is provided. The CU includes a computer for processing at least part of the method and for communicating with a server over a network. The method includes receiving, by the server, status information from the computer of the CU. The method includes sending to the computer of the CU instructions to make a reservation for the CU. The reservation is for a user account that has requested a desire to charge the battery of the electric vehicle of the user at the CU or another CU. The method includes sending, by the server, a confirmation for the reservation to the user account. The confirmation is viewable via a device having access to the server via the user account. The method includes sending, by the server, a data regarding a time of availability of the CU to the user account for the reservation. The computer of the CU is configured to display a visual indicator regarding the reservation of the CU.

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.

A vehicle provides information on a plurality of chargers that charge a battery mounted on the vehicle. The vehicle includes a navigation screen and an ECU. The ECU controls the navigation screen to show a map and to show a plurality of icons corresponding to the plurality of chargers at corresponding positions of the plurality of chargers on the map. The ECU controls the navigation screen to show the plurality of icons to allow identification of a charging type to which each of the plurality of chargers is adapted and magnitude of electric power that can be output under the charging type.

Integration between unmanned aerial system and unmanned ground robotic vehicle are disclosed herein. One variation of a robotic system may generally comprise an unmanned aerial vehicle (UAV), an unmanned ground vehicle (UGV), and a base station configured to receive the UAV and replace a spent power supply cartridge from the UAV and further having a charging mechanism configured to wirelessly transfer power to the UGV when the UGV is positioned in proximity to the charging pad.

Systems and methods are provided for presenting information related to electric charging stations for charging an electric vehicle. A first plurality of icons corresponding to an identified plurality of electric charging stations may be generated for presentation on a display. A zoom command to modify a zoom level of the map interface may be received, and in response to receiving the zoom command, a subset of the plurality of electric charging stations having a charging speed above a threshold charging speed may be identified, and a second plurality of icons, corresponding to the identified subset of the plurality of electric charging stations, may be generated for presentation at the display on a zoomed-out view of the map interface. Selectable options to display a detailed view of information related to an electric charger associated with an electric charger category from among multiple electric charger categories may be provided.

A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.

Technology for charging at least one battery is described. An aspect of the technology involves charging a battery using alternating current (AC) power by periodically stopping (602) charging of a battery of a mobile energy storage and power consumption device (16A) with AC power, and when charging of the battery with AC power is stopped, initiating (604) a direct current (DC) power charging communications cycle for the battery, in which the initiating the DC power charging communications cycle includes obtaining (606) state of battery related information for the battery by transmitting, over a communication link or interface, a request signal to a charging control device at the mobile energy storage and power consumption device indicating DC power charging mode of operation.
