A battery segment having a deterioration degree of more than 40% does not satisfy the storage amount required for the battery segment mounted on the vehicle 200, and may be regarded as an error. The secondary battery in error may be replaced. Since the amount of electricity stored in the secondary battery changes depending on the deterioration state of the secondary battery, the deterioration state of the secondary battery affects the traveling range of the vehicle 200. The estimation unit 130 associates the information indicating the estimation result of the deterioration state of the secondary battery with the vehicle identification information and outputs the information to the derivation unit 140.

The derivation unit 140 acquires the information indicating the estimation result of the deterioration state of the secondary battery output by the estimation unit 130 and the vehicle identification information.

The derivation unit 140 acquires information indicating the valuation amount stored in association with the identification information of the purchased vehicle among the vehicle identification information of the vehicle valuation amount information 164 stored in the storage unit 160.

For example, information indicating the deterioration state of the secondary battery and information associated with the evaluation value of the vehicle 200 are prepared, and the derivation unit 140 has information indicating the deterioration state of the secondary battery and the evaluation of the vehicle 200. The valuation price of the purchased vehicle may be derived by referring to the information associated with the price. The out-licensing unit 140 derives a guaranteed amount, which is a price for guaranteeing the valuation amount when the purchased vehicle 200 is sold, based on the acquired valuation amount and the derived valuation amount of the purchased vehicle 200. Specifically, the out-licensing unit 140 derives the guaranteed amount by subtracting the evaluated amount of the purchased vehicle 200 from the acquired evaluation amount. The derivation unit 140 outputs the identification information of the purchased vehicle and the information indicating the guarantee amount to the guarantee processing unit 150.

FIG. 6 is a diagram showing an example of deriving the guaranteed amount. In FIG. 6, the horizontal axis is time and the vertical axis is the battery evaluation value. The vertical axis may be the deterioration rate of the battery. The time when the sales of the vehicle 200 is started is referred to as "T1", and the time when the vehicle 200 is purchased by the user U is referred to as "T2". An example of when the vehicle 200 is started to be sold is at the time of sales start, and an example of when the vehicle 200 is purchased by the user U is at the time of secondary user purchase. Since the secondary battery is left between T1 at the start of sales and T2 at the time of purchase by the secondary user, it deteriorates over time. Due to this aging deterioration, the battery valuation is often reduced.
