초록

A method and apparatus for diagnosing the status of a battery having high and low voltage plateau states corresponding to its state of charge in which the battery open circuit voltage is measured (S106) to determine its voltage state and its internal resistance also is measured (S114). A battery having a low voltage state (S116) is tested to determine if its internal resistance is greater than a predetermined maximum resistance (S118) and if it does the battery is considered as possibly having a low electrolyte level, and if it does not the battery is su...
