Technical Examples
  1. The method comprises coupling an external load having a predetermined resistance directly in series with the battery, conducting a power transistor to supply a transient large current to the battery for sampling voltage of the battery in a set very short period of time, and determining the internal resistance of the battery. The internal resistance of the battery can then be compared with a predetermined warning value of internal resistance of the battery so as to determine whether the former is equal to or larger than the warning value, and displaying a warning on a display if the determination is affirmative. The invention enables a driver to correctly know the condition of the battery in substantially real time while consuming a minimum amount of current.
