Abstract:
The present invention relates to a current sensor diagnosis method, a current sensor diagnosis system providing the method, and a battery system. The current sensor diagnosis system of the present invention comprises: a first current sensor; a second current sensor connected in series with the first current sensor; a communication unit for receiving a first current value measured by the first current sensor and a second current value measured by the second current sensor; and a control unit for selecting a current section to which the first current value and the second current value belong, from among a plurality of current sections distinguished by the magnitudes of current, calculating a difference value between the first current value and the second current value, and diagnosing states of the first current sensor and the second current sensor by comparing a section reference value corresponding to the selected current section with the difference value.
