Abstract
A secondary battery state detecting apparatus for detecting a state of a secondary battery installed in a vehicle is provided, which includes a current detecting unit that detects an electric current flowing to the secondary battery, a voltage detecting unit that detects a voltage of the secondary battery, and a determining unit that determines, in a case where an external device is directly connected to terminals of the secondary battery and the secondary battery is charged or discharged without passing through the current detecting unit, whether or not an irregular charging-discharging has occurred, in accordance with a change in a current value and a voltage value detected by the current detecting unit and the voltage detecting unit.
