Title:
バッテリー状態診断装置及び方法
Document Type and Number:
Japanese Patent JP7473106
Kind Code:
B2
Abstract:
An apparatus for diagnosing a state of a battery according to an embodiment of the present disclosure includes a profile obtaining unit configured to obtain a voltage profile of a battery for voltage and capacity of the battery; and a control unit configured to obtain a differential profile for the voltage and the capacity from the voltage profile obtained by the profile obtaining unit, select a plurality of peaks included in a predetermined voltage section from the obtained differential profile, determine a first peak associated with a negative electrode and a second peak associated with a positive electrode among the plurality of selected peaks, compare the first peak and the second peak with a first reference peak and a second reference peak of a preset reference profile, respectively, and diagnose a state of the battery in consideration of at least one of a behavior change of the first peak with respect to the first reference peak and a behavior change of the second peak with respect to the second reference peak.
