Abstract

There is provided a service system that allows a user to charge and repeatedly use a secondary battery and exchanges a battery pack for a charged battery pack. There is provided a battery exchange service system in which a terminal is connected to a management server. The terminal includes an information obtaining unit that obtains battery information and user information; a charging and discharging unit that charges and discharges a battery pack; and a power information generation unit that generates information on an amount of electricity based on the charging and discharging by the charging and discharging unit. The management server includes a battery information database that stores battery information distributed in the battery exchange service system; a contractor information database that stores contractor information for the battery exchange service system; a battery information verification unit that verifies the battery information by the battery information stored in the battery information database; a user information verification unit that verifies the user information by the contractor information stored in the contractor information database; and a charge calculation unit that calculates a charge based on the information on the amount of electricity.

Claims

1. A battery exchange service system comprising:

a terminal and a management server connected with each other;

wherein the terminal includes;

an information obtaining unit for obtaining battery information and user information;

a charging and discharging unit for charging or discharging a battery pack;

a power information generation unit for generating information on an amount of electricity based on charging or discharging by the charging and discharging unit; and

an information transmission unit for transmitting to the management server the battery information, the user information, and the information on the amount of electricity; and

wherein the management server includes;

an information reception unit for receiving the battery information, the user information, and the information on the amount of electricity from the terminal;

a battery information database for storing battery information distributed in the battery exchange service system;

a contractor information database for storing contractor information for the battery exchange service system;

a battery information verification unit for verifying the battery information by the battery information stored in the battery information database;

a user information verification unit for verifying the user information by the contractor information stored in the contractor information database;

a charge calculation unit for calculating a charge based on the information on the amount of electricity; and

a transmission unit for transmitting to the terminal a result of verification of the user information, a result of verification of the battery information, and the charge; and

wherein the power information generation unit generates information on an amount of electricity based on a difference between an amount of charge of a first battery pack to be provide to a user and an amount of charge remaining in a second battery pack taken back from the user.

2. The battery exchange service system according to claim 1, wherein the amount of charge of the first battery pack is determined based on an amount of charge immediately before the first battery pack is given to the user.

3. The battery exchange service system according to claim 1, wherein the charging and discharging unit has a function of regenerating power discharged from the second battery pack.

4. The battery exchange service system according to claim 1, wherein the terminal further includes;

a dropping opening for the second battery pack; and

a take-out opening for the first battery pack, and the charging and discharging unit further includes a control unit for fully charging a battery pack present near the take-out opening.

5. The battery exchange service system according to claim 1, wherein the management server further includes;

an amount-of-power-generation information reception unit for receiving information on an amount of power generation of renewable energy; and

an information processing unit for calculating an amount of sales of renewable energy that can be sold, based on the information on the amount of power generation and the information on the amount of electricity.

6. The battery exchange service system according to claim 5, wherein the terminal further includes a display unit for displaying any one of the information on the amount of power generation of the renewable energy, information on an amount of electricity sold by the battery exchange service, and information on a difference between the amount of power generation and the amount of electricity sold.

7. A terminal of a battery exchange service system, the terminal being connected to a management server and comprising:

an information obtaining unit for obtaining battery information and user information;

a charging and discharging unit for charging and discharging a battery pack;

a power information generation unit for generating information on an amount of electricity based on charging and discharging by the charging and discharging unit;

an information transmission unit for transmitting to the management server the battery information and the user information obtained by the information obtaining unit and the information on the amount of electricity generated by the power information generation unit; and

a reception unit for receiving the battery information and the user information stored in an information storage unit of the management server, information on results of verification of the transmitted battery information and the transmitted user information, and information on a charge calculated by a charge calculation unit of the management server based on the transmitted information on the amount of electricity; and

wherein the power information generation unit generates information on an amount of electricity based on a difference between an amount of charge of a first battery pack to be provided to a user and an amount of charge remaining in a second battery pack taken back from the user.
