System for managing vehicle battery replacement

A system comprising:

• a management apparatus;
• a dealer terminal that is a computer that provides for each sold vehicle a vehicle ID that identifies the sold vehicle, wherein
• the management apparatus comprises:
• a processor;
• and
• a storage that stores management information;
• the dealer terminal is configured to:
• determine whether a vehicle purchaser has agreed to post-purchase battery replacement when the vehicle purchaser purchases a vehicle including a secondary battery, the post-purchase battery replacement being replacement of the secondary battery when a degree of deterioration of the secondary battery reaches a prescribed threshold value after purchase of the vehicle,
• present a first sales price to the vehicle purchaser when the vehicle purchaser does not agree to the post-purchase battery replacement,
• present a second sales price lower than the first sales price to the vehicle purchaser when the vehicle purchaser has agreed to the post-purchase battery replacement, and
• transmit contract information showing contents of a sales-and-purchase contract to the management apparatus when the vehicle purchaser approves purchase of the vehicle, and
• the management apparatus is configured to:
• update the management information that is stored in the storage with the contract information received from the dealer terminal, the management information including the contract information for each sold vehicle distinguished from each other based on the vehicle ID, the contract information including contract replacement information indicating whether each sold vehicle is a subject vehicle, the subject vehicle being a vehicle purchased by a vehicle purchaser who has agreed to the post-purchase battery replacement, and
• determine whether each of a plurality of vehicles managed by the management apparatus is the subject vehicle based on the contract replacement information;
• and
• the subject vehicle, wherein
• the subject vehicle includes a monitoring unit configured to monitor the secondary battery mounted on the subject vehicle to obtain and store in memory history information showing history of use of the secondary battery, the history information showing a frequency distribution during a prescribed period of at least one of an SOC, a charging current, a discharging current, and a temperature of the secondary battery mounted on the subject vehicle,
• the history information stored in the memory of the subject vehicle is transmitted to the management apparatus,
• the management apparatus is configured to periodically estimate a degree of deterioration of the secondary battery mounted on the subject vehicle based on the history information,
• the management apparatus is configured to, in response to the degree of deterioration of the secondary battery being estimated, compare the degree of deterioration of the secondary battery to the prescribed threshold value,
• when the management apparatus determines that the degree of deterioration of the secondary battery that has been estimated reaches the prescribed threshold value, the management apparatus is configured to transmit a notification signal indicating battery replacement timing of the subject vehicle to the dealer terminal, and
• the dealer terminal is configured to, when the dealer terminal receives the notification signal from the management apparatus, transmit a signal inviting a user of the subject vehicle to replace the secondary battery to at least one of a communication apparatus mounted on the subject vehicle and a portable terminal carried by the user of the subject vehicle, which causes an invitation message to be displayed on a display screen of the communication apparatus.
