ACTIVE PAIRING METHOD AND DEVICE FOR WIRELESS LAN-BASED SMART CHARGING OR SMART CHARGING AND DISCHARGING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18032615 titled 'ACTIVE PAIRING METHOD AND DEVICE FOR WIRELESS LAN-BASED SMART CHARGING OR SMART CHARGING AND DISCHARGING

Simplified Explanation

The patent application describes an active pairing method and device for wireless smart charging or smart charging and discharging in electric vehicles.

  • The method eliminates the need to restart a V2GTP communication session of an Electric Vehicle Communication Controller (EVCC).
  • The method involves transmitting an SDP request message from the electric vehicle to a supply equipment communication controller (SECC) Discovery Protocol (SDP) server.
  • The SDP request message includes an EVID (Electric Vehicle ID) to identify the electric vehicle.
  • The electric vehicle receives an SDP response message from the SDP server, which contains information about a specific SECC that controls the electric vehicle supply equipment (EVSE) where the vehicle is parked or plugged into.
  • This active pairing method simplifies the process of connecting the electric vehicle to the appropriate charging equipment.

Original Abstract Submitted

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.
