본 발명은 전기차량 충전장치의 충전케이블 및 플러그의 자체 저항으로 인한 전력손실로 인해 전기차량 충전장치로부터 공급되는 전력량과 실제 차량으로 공급되는 전력량의 오차를 정확하게 산출함과 동시에 산출된 오차율을 적용하여 전력을 공급하도록 구성됨으로써 전력계량 및 충전서비스에 대한 신뢰도 및 정확성을 높일 수 있을 뿐만 아니라 전력량 오차로 인한 소비자의 비용소모를 절감시킬 수 있으며, 기준계 전력량 산출단계(S60) 및 기준전력량계 전력량 산출단계(S70)가 수학식 1을 이용하여 기준계 전력량(Nnom) 및 기준전력량계 전력량(Nact)을 산출함과 동시에 오차율 산출단계(S80)가 수학식 2를 이용하여 충전전력량의 오차율(δWdut)을 산출하도록 구성됨으로써 연산처리의 속도 및 정확성을 개선시킬 수 있는 전기차량 충전장치의 오차 측정 방법 및 이를 이용한 충전 관리시스템에 관한 것이다.
The present invention relates to an error measuring method for a charger of an electric vehicle and a charging management system using the same. The error measuring method for a charger of an electric vehicle accurately calculates an error of an electric power amount actually supplied to an electric vehicle and the electric energy amount supplied by a charger of the electric vehicle, caused by a loss of electric power due to resistance of a plug and a charging cable of the charger of the electric vehicle. At the same time, the error measuring method for a charger of an electric vehicle supplies the electric power by applying a calculated error rate, thereby improving reliability and accuracy on an energy metering and charging service and reducing cost consumption of a consumer due to the error of the electric power amount. The error measuring method for a charger of an electric vehicle includes: a reference system power amount calculating step (S60) and a reference watt-hour meter power amount calculating step (S70) of calculating a reference system power amount (N_nom) and a reference watt-hour meter power amount (N_act) by using equation 1; and an error rate calculating step (S80) of calculating the error rate (Δw_dut) of a charging power amount by suing equation 2. Therefore, the error measuring method for a charger of an electric vehicle can improve speed and accuracy of calculation processing.
