Zusammenfassung: | Disclosed is a vehicle battery diagnosing method including the following steps of: allowing a controller to end charging of a battery by stopping supplying a current from a charger to the battery; allowing the controller to measure a relaxation voltage corresponding to a decrease amount of a battery voltage for a preset time immediately after the charging of the battery is terminated; and allowing the controller to estimate a degree of deterioration of the battery based on the relaxation voltage.
컨트롤러에서, 충전기로부터 배터리로 전류를 공급을 중단하게 하여 상기 배터리의 충전을 종료하는 단계; 상기 컨트롤러에서, 상기 배터리의 충전이 종료된 직후 사전 설정된 시간 동안의 상기 배터리 전압의 감소량에 해당하는 이완 전압을 측정하는 단계; 및 상기 컨트롤러에서, 상기 이완 전압을 기반으로 상기 배터리의 열화도를 추정하는 단계를 포함하는 차량용 배터리 진단 방법이 개시된다. |
