Abstract: A server includes: a communication unit that communicates with a mobile terminal (terminal) of a user; and a processor (control unit) that controls the communication unit. When the communication unit has not received deterioration information (battery information) on a battery from the mobile terminal for greater than or equal to a cycle (predetermined period), the processor performs control for obtaining the deterioration information through the mobile terminal.

Abstract: A server includes: a communication unit (acquisition unit) that acquires information of a capacity retention (degree of degradation) of a battery (secondary battery); and a processor (control unit) that calculates a lease fee of the battery using the information of the capacity retention. The processor performs suppression processing for suppressing an increase of the lease fee, the increase of the lease fee being based on deterioration (decrease) of the capacity retention due to an environment in which the electrically powered vehicle is used.

Abstract: A server includes: a communication unit (acquisition unit) that acquires information about a degree of degradation of a battery (secondary battery); and a processor (control unit) that calculates a lease fee of the battery using the information about the degree of degradation of the battery. The processor performs suppression processing for suppressing an increase of the lease fee, the increase of the lease fee being based on deterioration of a degree of discharging-caused degradation caused by discharging in response to a request for adjusting a power demand/supply state in a power system (PG).

Abstract: A data management system includes a data management device and an arithmetic device. The data management device is configured to acquire battery data and store, in a distributed ledger, transaction data including information on the acquired battery data. The arithmetic device is configured to acquire the battery data from the data management device and calculate an index using the battery data and a predetermined arithmetic formula. The arithmetic device is configured to offer the index to a disclosure server.

Abstract: A vehicle diagnostic system diagnoses a vehicle having a battery mounted thereon. The vehicle diagnostic system includes an instrument panel for showing a capacity retention of the battery, and an ECU that calculates the capacity retention to be displayed on the instrument panel. The ECU measures the full charge capacity of the battery each time external charging is completed, and, based on a result of the measurement, updates a capacity deterioration curve indicative of changes in over time of the capacity retention. When a display request for showing the capacity retention on the instrument panel is generated, the ECU calculates the capacity retention when the display request is generated by referring to the updated capacity deterioration curve.

Abstract: A battery diagnostic system includes a diagnostic server that diagnoses a battery mounted on a vehicle using battery information including usage information of the battery while the battery is mounted on the vehicle, and a diagnostic terminal that acquires the battery information from the vehicle, transmits the battery information to the diagnostic server, and receives a diagnoses result of the battery from the diagnostic server. When the diagnostic terminal transmits the battery information to the diagnostic server, the diagnostic terminal transmits information on whether a predetermined condition is satisfied together with the battery information to the diagnostic server. The diagnostic server accumulates the battery information when the predetermined condition is satisfied, and deletes the battery information after diagnosing the battery when the predetermined condition is not satisfied.

Abstract: A processing device of a server provides a predetermined price, based on battery information received by a communication device, to a user of a vehicle that transmits the battery information. The processing device provides a user of a vehicle transmitting second information as the battery information with a price higher than that provided to a user of a vehicle transmitting first information as the information, it being determined that there is a larger need for collecting the second information than the first information.
