DIAGNOSING AND LOCATING BATTERY PACK FAILURES

A vehicle system includes a battery pack including a plurality of battery cells, a voltage sensor configured to sense an output voltage of the plurality of battery cells, and a control module in communication with the voltage sensor. The control module is configured to detect a failure associated with the battery pack, receive, from the voltage sensor, a first voltage signal representing a first voltage value and a second voltage signal representing a second voltage value, determine a defined ratio of the first voltage value and the second voltage value, determine a battery cell location of the detected failure in the battery pack based on the defined ratio and a total number of the plurality of battery cells in the battery pack, and generate an alert indicating the battery cell location of the detected failure. Other example vehicle systems and methods are also disclosed.
