ANOMALY DETECTION IN HIGH-VOLTAGE BUS SYSTEMS

Methods and systems are provided for troubleshooting anomalies in a high-voltage bus system for an electrified vehicle are provided herein. The high-voltage bus system being electrically connected to a plurality of electrical components such that each electrical component in the plurality of electrical components has a similar voltage when the high-voltage bus system is electrified. The method includes detecting individual voltages for each electrical component in the plurality of electrical components using a voltage sensor of each of the electrical components in the plurality of electrical components; determining a baseline voltage for each of the electrical components in the plurality of electrical components, the baseline voltage corresponding to at least a subset of the individual voltages; and comparing any one of the individual voltages to the baseline voltage to determine if that individual voltage is anomalous.
