Abstract

A battery charger for charging a battery includes a charger; an acquisition unit acquiring information of the battery; and a control unit setting a charging condition of the battery based on the information of the battery and controlling the charger.

Claims

1. A battery charger for charging a battery, the battery charger comprising,

a charger;

an acquisition unit configured to acquire information of the battery; and

a control unit configured to set a charging condition of the battery based on the information of the battery and control the charger.

2. The battery charger according to claim 1,

wherein the control unit is configured to perform control to display the charging condition settable based on the information of the battery and set the charging condition input by a user.

3. The battery charger according to claim 1,

wherein the control unit is configured to perform control to display two or more of the charging conditions, where charging rates are different from each other, based on the information of the battery.

4. The battery charger according to claim 1,

wherein the control unit is configured to perform control to display a charging condition settable based on environmental setting information and set the charging condition input by a user.

5. The battery charger according to claim 4,

wherein the environmental setting information includes temperature information, maximum charging time, or maximum charging power.

6. The battery charger according to claim 5, further comprising:

an information processing apparatus configured to monitor charging power amounts of two or more of the battery chargers and set the environmental setting information based on the charging power amounts,

wherein the control unit is configured to perform control to display a charging condition settable based on environmental setting information set by the information processing apparatus.

7. The battery charger according to claim 1,

wherein the acquisition unit is configured to acquire information of the battery using a near field communication technique.

8. The battery charger according to claim 1,

wherein the information of the battery includes a battery type name, a battery capacity value, or a battery remaining amount.

9. The battery charger according to claim 1,

wherein the charging condition includes charging time or charging amount.

10. (canceled)

11. A battery charging method for charging a battery, the method comprising:

acquiring information of the battery;

setting a charging condition of the battery based on the information of the battery; and

controlling the charger.

12. A battery charging system comprising:

two or more battery chargers configured to charge batteries at charging rates in accordance with types of the batteries; and

a power supply apparatus configured to supply power to the battery chargers,

wherein the battery chargers include

an acquisition unit configured to acquire the types of the batteries connected to the battery chargers,

a charging rate setting unit configured to set the charging rates in accordance with the batteries based on the types of the batteries,

a control unit configured to control chargers to charge at the charging rates set by the charging rate setting unit, and

a communication unit configured to send the charging rates set by the charging rate setting unit to the power supply apparatus,

wherein the power supply apparatus includes

a storage unit configured to store a maximum value of a power amount supplied by the power supply apparatus,

a scheduling unit configured to perform scheduling that acquires power amounts to be supplied to the battery chargers per unit time based on the maximum value of the power amount stored in the storage unit and the charging rates sent from the battery chargers, and

an adjusting unit configured to adjust a total amount of power to be supplied to the battery chargers based on the scheduling performed by the scheduling unit.

13. A battery charging system according to claim 12,

wherein the scheduling unit is configured to, when a charging rate is newly reported from a battery charger, acquire a power amount to be supplied to the battery charger newly reported the charging rate based on the maximum value of the power amount stored in the storage unit and the power amounts supplied in a previous scheduling.
