Charger selection system, charger selection method, and charger selection program

A charger selection method comprising:

• providing a plurality of first charge control maps respectively associated with a plurality of chargers, and
• providing a plurality of second charge control maps respectively associated with a plurality of electrically driven vehicles each having a secondary battery mounted thereon,
• wherein each of the first charge control maps specifies a first upper limit current for a corresponding one of the plurality of chargers to charge the secondary battery, the first upper limit current dependent on one or more of a temperature of the charger, a state of charge (SOC) of the secondary battery, a voltage of the secondary battery, and time,
• wherein each of the second charge control maps specifies a second upper limit current for charging the secondary battery of a corresponding one of the plurality of electrically driven vehicles, the second upper limit current dependent on one or more of a temperature of the secondary battery, the SOC of the secondary battery, the voltage of the secondary battery, and time, and
• selecting, by referring to one or more of the first charge control maps and one of the second charge control maps corresponding to an electrically driven vehicle to be charged, at least one charger that least limits the charging performance of the electrically driven vehicle to be charged from among the plurality of chargers, wherein the method further comprises:
• acquiring a charging log from any one charger of the plurality of chargers;
• and
• updating a first charge control map associated with the any one charger based on the acquired charging log.

A non-transitory computer-readable recording medium having embodied thereon a charger selection program, the charger selection program causing a computer to execute:

• referring to one or more of a plurality of first charge control maps respectively associated with a plurality of chargers, and
• referring to one or more of a plurality of second charge control maps respectively associated with a plurality of electrically driven vehicles each having a secondary battery mounted thereon,
• wherein each of the first charge control maps specifies a first upper limit current for a corresponding one of the plurality of chargers to charge the secondary battery, the first upper limit current dependent on one or more of a temperature of the charger, a state of charge (SOC) of the secondary battery, a voltage of the secondary battery, and time,
• wherein each of the second charge control maps specifies a second upper limit current for charging the secondary battery of a corresponding one of the plurality of electrically driven vehicles, the second upper limit current dependent on one or more of a temperature of the secondary battery, the SOC of the secondary battery, the voltage of the secondary battery, and time, and
• selecting, by referring to one or more of the first charge control maps and one of the second charge control maps corresponding to an electrically driven vehicle to be charged, at least one charger that least limits the charging performance of the electrically driven vehicle to be charged from among the plurality of chargers,
• wherein the charger selection program causes the computer to further execute:
• acquiring a charging log from any one charger of the plurality of chargers;
• and
• updating a first charge control map associated with the any one charger based on the acquired charging log.
