<P>PROBLEM TO BE SOLVED: To estimate deterioration condition of a used battery after battery replacement in consideration of a vehicle use method by a user, and retrieve a used battery suitable for the user on the basis of the estimated deterioration condition. <P>SOLUTION: On the basis of pieces of vehicle information on a battery to be replaced and on substitute candidate battery, a vehicle use method by a user is analysed (step S2). Deterioration condition of the substitute candidate battery after the user of the battery to be replaced replaces it with the substitute candidate battery is estimated on the basis of a running distance at a replacement timing with the substitute candidate battery and a deterioration curve corresponding to the vehicle use method by the user of the battery to be replaced (Steps S4 and S8). On the basis of the estimated deterioration condition of the substitute candidate battery, a used battery affording a running distance suitable for the vehicle use method by the user of the battery to be replaced and satisfying the desire of the user of the battery to be replaced in terms of a usable period and a price is selected (Step S5, Steps S9 to S11), and presented as the optimal battery in a user terminal 7 (Step S12). <P>COPYRIGHT: (C)2013,JPO&INPIT |
