Abstract: front page image
(EN)Disclosed are a charger which is capable of diagnosing the lifespan of a battery when the battery is charged and a control method therefor. The charger comprises: a converter for applying a perturbation voltage or a perturbation current to a battery; and a digital signal processor for transferring a perturbation signal, in which an alternating current signal is added to a direct current signal, to the converter, measuring an output response of the battery, calculating an impedance spectrum according to the output response of the battery, designating an equivalent circuit according to the impedance spectrum, thereby calculating an impedance parameter, and estimating the lifespan of the battery by comparing the calculated impedance parameter of the battery with a predetermined impedance parameter of a reference battery. Thus, the present invention can detect sudden failure signs and the like in advance by pre-diagnosing the lifespan of a battery and can reduce post-processing and managing costs due to the failure of the battery.
(FR)L'invention porte sur un chargeur qui peut diagnostiquer la durée de vie d'une batterie lorsque la batterie est chargée et sur son procédé de commande. Le chargeur comprend : un convertisseur destiné à appliquer une tension de perturbation ou un courant de perturbation à une batterie; et un processeur de signal numérique destiné à transférer au convertisseur un signal de perturbation dans lequel un signal de courant alternatif est ajouté à un signal de courant continu, à mesurer une réponse de sortie de la batterie, à calculer un spectre d'impédance selon la réponse de sortie de la batterie, à désigner un circuit équivalent selon le spectre d'impédance, ce qui permet de calculer un paramètre d'impédance, et à estimer la durée de vie de la batterie par comparaison du paramètre d'impédance calculé de la batterie à un paramètre d'impédance prédéterminé d'une batterie de référence. Ainsi, la présente invention peut détecter à l'avance des signes de défaillance soudains, et analogues, en en réalisant un prédiagnostic de la durée de vie d'une batterie et peut réduire les coûts de post-traitement et de gestion dus à la défaillance de la batterie.
(KO)배터리의 충전 시 배터리의 수명을 진단할 수 있는 충전기 및 그 제어방법을 개시한다. 충전기는 배터리에 섭동전압 또는 섭동전류를 인가하는 컨버터 및 컨버터로 직류 신호에 교류 신호를 부가시킨 섭동 신호를 전달하고, 배터리의 출력 응답을 측정하며, 배터리의 출력 응답에 따라 임피던스 스펙트럼을 산출하며, 임피던스 스펙트럼에 따라 등가회로를 선정하여 임피던스 파라미터를 산출하며, 배터리의 산출된 임피던스 파라미터와 미리 정해진 기준배터리의 임피던스 파라미터를 비교하여배터리의 수명을 추정하는 디지털 신호 프로세서를 포함하므로, 배터리의 수명을 미리 진단하여 갑작스런 고장 징조 등을 사전에 감지할 수 있고, 배터리의 고장으로 인한 사후 처리 및 관리 비용을 감소시킬 수 있다.
