The objective of this paper is to present a fault diagnosis methodology for hybrid electric vehicle battery systems. The faults that have been considered include: temperature sensor fault, current sensor fault, and voltage sensor. Many of these faults, if left undetected, will result in decreased battery performance and could eventually lead to pack failure.
