    摘要: Disclosed are methods and systems for preventing battery failure by identifying battery maintenance actions for a vehicle system. For instance, a method may include receiving at least one thermal image corresponding to at least one battery of at least one vehicle, converting the at least one thermal image into one or more parameters, transmitting the one or more parameters to a condition monitoring system, evaluating the one or more parameters based on one or more conditions to determine that at least one of the one or more parameters meet at least one of the one or more conditions, determining one or more battery maintenance actions based on the at least one of the one or more parameters that meets the at least one of the one or more conditions, and outputting the one or more battery maintenance actions to one or more user interfaces of a user device.
