Abstract
A current sensor diagnosing apparatus for diagnosing an error of a plurality of current sensors connected to a secondary battery cell. The current sensor diagnosing apparatus may diagnose an error of a current sensor in the same way regardless of the type of a system using the current sensor, the type of a current source, a voltage characteristic, or the like by diagnosing an error of current sensors using offset deviations and current values of two current sensors and may be particularly applied to various systems including a plurality of current sensors.
