A method, for determining when a first battery within a vehicle should be swapped with a second battery at a swap station, performed by a server apparatus, the server apparatus including a processor and a memory storing identification information that identifies the swap station and location information that indicates a location of the swap station, the method comprising:

  • acquiring, using the processor, first battery information from an information presentation device within the vehicle, wherein the first battery information includes i) a charge level of the first battery within the vehicle, and ii) first history information about the first battery, wherein the first history information indicates a first value related to performance of the first battery;

    assessing, using the processor, a first rank of the first battery based on the first value indicated by the acquired first history information when the charge level of the first battery is lower than a predetermined level;

    acquiring, using the processor, the identification information and second battery information from an information processing device that manages the second battery that is placed at the swap station, wherein the second battery information includes second history information about the second battery, wherein the second history information indicates the second value related to performance of the second battery, and wherein the second battery is installable in the vehicle in place of the first battery;

    assessing, using the processor, a second rank of the second battery based on the second value indicated by the acquired second history information;

    comparing, using the processor, the assessed first rank of the first battery within the vehicle to the assessed second rank of the second battery placed at the swap station;

    generating, using the processor, output information that includes information indicating the location of the swap station based on the location information stored in the memory when the processor determines that the assessed second rank is equal to or higher than the assessed first rank; and

    outputting, using the processor, the generated output information to the information presentation device of the vehicle to guide the vehicle to the swap station.
