摘要： A method for measuring a position, is performed by a vehicle assembly (VA) for alignment between a ground assembly (GA) and the VA. The method includes transmitting low frequency (LF) signals to initiate alignment with the GA and estimating a position of a vehicle using at least one sensor mounted on the vehicle. Information regarding the estimated position of the vehicle is provided to the GA and information regarding a position of the vehicle measured by LF receive antennas of the GA and an acceleration flag calculated by the GA is received. Accordingly, a transmission strength of the LF signals transmitted by the VA is adjusted based on the information regarding the position of the vehicle measured by the LF receive antennas and the acceleration flag.

摘要： Disclosed are an active earlier pairing method and device for wireless LAN-based smart charging or smart charging and discharging, wherein it is not necessary to restart a V2GTP communication session of an Electric Vehicle Communication Controller (EVCC). An active pairing method performed by an electric vehicle (EV) comprises the steps of: transmitting, to a supply equipment communication controller (SECC) Discovery Protocol (SDP) server, an SDP request message including an EVID by which the EV can be identified; and receiving, from the SDP server communicating with SECCs, an SDP response message including information indicating a specific SECC that controls electric vehicle supply equipment (EVSE) in which the EV parks or into which the EV is plugged.

摘要： A method for estimating distance using low frequency (LF) signals when performing fine positioning for electric vehicle (EV) wireless power transfer (WPT) includes steps of: restricting a position of a first transmitter of an EV to a point on a first straight line extending towards a center of a primary device of a power supply device; restricting a position of a second transmitter of the EV to a point on a second straight line extending towards the center of the primary device; compensating, on the first straight line or the second straight line, for the distance between the first transmitter and the second transmitter based on the time difference of LF signals arriving at the primary device; and calculating the positions of the first and second transmitters such that first and second distances from starting points on the first and second straight lines to the first and transmitters, respectively.
