Abstract
A method for detecting a fault in a direct current (DC) battery of a pitch system includes receiving, via a server, a plurality of voltage signals of the battery over at least one time period. The method also includes storing, via a database of the server, the plurality of voltage signals of the battery for the predetermined time period. Further, the method includes determining, via the server, a state of the battery as a function of the plurality of voltage signals. When the state of the battery is indicative of a battery fault, the method includes implementing a corrective action for the battery.
