진단 대상 기기(배터리 셀)의 상태를 측정하는 측정부[셀 전압 측정부(202)]와, 그 측정 결과에 기초하여 진단 대상 기기의 이상을 판정하는 제1 이상 판정부[과전압·과방전 판정부(203)]와, 동일하게 측정 결과에 기초하여 진단 대상 기기의 이상을 판정하는 제2 이상 판정부[주연산기(301)]를 갖는다. 측정부(202)와 제1 이상 판정부(203)를 제1 기판[셀 상태 측정부(101)]에 설치하는 한편, 제2 이상 판정부(301)를 제1 기판과는 다른 제2 기판(셀 상태 연산부)에 설치하여, 공통 고장 인자(기판)에 의한 고장율의 저감을 도모한다.

    An abnormality diagnosis device includes: a measurement unit (cell voltage measurement unit (202)) for measuring the state of a device to be diagnosed (battery cell); a first abnormality determination unit (overvoltage and over-discharge determination unit (203)) for determining the abnormality of the device to be diagnosed on the basis of the measurement results; and a second abnormality determination unit (main processing unit (301)) for similarly determining the abnormality of the device to be diagnosed on the basis of the measurement results. The measurement unit (202) and the first abnormality determination unit (203) are provided on a first substrate (cell state measurement unit (101)), while the second abnormality determination unit (301) is provided on a second substrate (cell state calculation unit) different from the first substrate, so that the failure rate due to a common failure factor (substrate) is reduced.
