<p>A method and apparatus (200) for estimating a condition of battery is disclosed. The apparatus (200) for estimating a condition for a battery comprises: a mode identifying unit (201) configured to identify a usage mode of the battery during a period of time and its corresponding attenuation curve, according to recorded data on battery usage, stored usage modes of the battery and attenuation curves corresponding to the various usage modes (SI), the attenuation curve representing a change of a fully charged capacity of the battery with battery usage; and a condition estimating unit (202) configured to calculate battery degradation according to the recorded data, the identified usage mode and its corresponding attenuation curve, the degradation representing a quantity of the fully charged capacity of the battery that is reduced over the battery usage (S2). The invention solves a problem of estimating the condition of the battery more correctly so as to more rationally judge the residual value of the battery in operation.</p> |
