ABNORMALITY DETECTOR OF ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an abnormality detector of an electric vehicle, which can relatively easily and accurately determine an abnormality in connection of a high-voltage circuit system.SOLUTION: An abnormality detector of an electric vehicle includes: a signal output part 22 that outputs an AC signal; a signal reception part 23 that receives the AC signal by a part between the signal output part 22 and a coupling capacitor 21; and an abnormality determination part 24 that determines the presence or absence of an abnormality in connection of a high-voltage circuit system 5 on the basis of an amplitude or wavelength of the received signal received by the signal reception part 23.
