Abstract
A battery management system includes: measuring a surface pressure of a vehicle-mounted secondary battery (battery cell) for driving the vehicle with a lapse of time; calculating a high-rate driving frequency coefficient on the basis of the measured surface pressure at intervals of a predetermined period (24 hours); deriving a high-rate driving frequency on the basis of the number of times that the calculated high-rate driving frequency coefficient has exceeded a predetermined threshold; and selecting a replacement battery from among batteries including a high-power battery on the basis of the derived high-rate driving frequency.
