Publication number: 20150137753Abstract: In a charging demand verification method of an eco-friendly vehicle (EV), an eco-friendly vehicle supply equipment (EVSE) receives a charging request from a communication controller of eco-friendly vehicle (EVCC). The EVSE receives an identification code value (PEVID), a moving distance value, and a request charging value from the EVCC. The EVSE transmits the received identification code value to a secondary actor (SA). The EVSE receives vehicle type information, a basic maximum charging value, an accumulated moving distance value, and a charging amount at a previous charging time. The EVSE compares the request charging value and denies the charging request of the EV when the request charging value is greater than the basic maximum charging value. The EVSE calculates a prediction value of power consumed by the EV, and charges the EV when the difference between the prediction value and the actual power value actually is within a predetermined error range.Type: ApplicationFiled: May 21, 2014Publication date: May 21, 2015Applicants: HYUNDAI MOTOR COMPANY, AJOU UNIVERSITY INDUSTRY - ACADEMIC COOPERATION FOUNDATIONInventors: Kang Ju CHA, Ji Hwon KIM, So Jin LEE, Tae Shik SHON
