CHARGING DEMAND VERIFICATION METHOD OF A ELECTRIC VEHICLE AND THE SYSTEM THEREOF

摘要

The present invention relates to a method for verifying the requested charging amount of an electronic vehicle (EV). The method includes: a step in which an electric vehicle supply equipment (EVSE) receives a charging request from a communication controller of the EV; a step in which identification code value (PEVID), a charging request (ChargingProfileMaxPower), and moving distance value from a communication controller; a step in which the EVSE transmits the PEVID to a secondary actor (SA); a step in which the EVSE receives the vehicle model information; default maximum charge value (ChargingProfileEntryMaxPower), accumulated travel distance valve at the latest charging point prior to the current point, and the charging amount; a step in which the EVSE compares the default maximum charge value received from the communication controller and the requested charging amount transmitted from the secondary actor; a step in which the EVSE denies the charging result of the EV or allow the EV to proceed to the next step according to the comparison result; a step in which the EVSE calculates the predicted power consumption value of the EV; and a step in which the EVSE allows the EV to be charged if the difference between the predicted power consumption value and the actual power consumption is within a predetermined error range.
