Summary:The technology of the present invention relates to a system and a method for diagnosing the deterioration of a vanadium redox flow battery (VRFB). According to an embodiment of the present invention, as the deterioration of a VRFB subject to field evaluation is automatically diagnosed based on data obtained according to a testing purpose of the VRFB subject to field evaluation, it is possible to reduce maintenance costs of the VRFB subject to field evaluation due to the deterioration diagnosis of the VRFB subject to field evaluation and to reduce labor costs and human errors for the deterioration diagnosis of the VRFB subject to field evaluation. Thus, the reliability of the VRFB can be improved. It is possible to select an overall average oxidation state and a time point of volume balancing from the results of the deterioration diagnosis of the VRFB subject to field evaluation, based on the maintenance rate compared to the initial design capacity of the VRFB subject to field evaluation. It is possible to reduce unnecessary power consumption caused by frequent testing during the operation of the VRFB, subject to field evaluation. 본 기술은 바나듐 레독스 흐름전지((VRFB: Vanadium Redox Flow Battery)의 열화진단 시스템 및 방법에 관한 것으로, 본 실시예의 구현 예에 따르면, 현장평가 대상 VRFB의 시험목적에 따라 획득된 데이터를 토대로 현장평가 대상 VRFB의 열화를 자동으로 진단함에 따라, 현장평가 대상 VRFB의 열화 진단으로 따른 현장평가 대상 VRFB의 유지 보수를 절감할 수 있고, 현장평가 대상 VRFB의 열화진단을 위한 인력비용 및 인적오류를 절감할 수 있는 효과가 있으며, 이에 VRFB의 신뢰성이 향상될 수 있으며, 현장평가 대상 VRFB의 열화 진단 결과로 현장평가 대상 VRFB의 초기 설계 용량 대비 유지율을 토대로 전체적인 평균 산화수 및 부피 밸런싱 시점을 선정할 수 있고 현장평가 대상 VRFB의 운영 시 잦은 시험을 통한 불필요한 전력소모량을 줄일 수 있다.
