Abstract

A method is provided that includes: receiving identification information of a power storage device that is connected to a charging device, and a value indicating the state of a storage battery included in the power storage device. The method also includes associating to each other and storing the identification information of the power storage device and the value indicating the state of the storage battery. Additionally, the method includes determining the possibility of charging the power storage device by comparing the received value indicating the state of the storage battery with a value indicating a past state of the storage battery that is stored and corresponds to the received identification information of the power storage device. The method further includes transmitting information indicating the determined possibility of charging the power storage device to at least one of the charging device and the power storage device.

Claims

1. A method comprising:

(a) receiving, by a receiver, identification information of a power storage device that is connected to a charging device, and a value indicating a state of a storage battery included in the power storage device, from at least one of the charging device and the power storage device;

(b) associating, by a storage, to each other and storing the identification information of the power storage device and the value indicating the state of the storage battery;

(c) prior to charging of the power storage device by the charging device being started, determining, by a determiner, a possibility of charging the power storage device by comparing the value indicating the state of the storage battery received from at least one of the charging device and the power storage device with a value indicating a past state of the storage battery that is stored and corresponds to the identification information of the power storage device received from at least one of the charging device and the power storage device; and

(d) transmitting by a transmitter, information indicating the determined possibility of charging the power storage device to at least one of the charging device and the power storage device; and

(e) permitting charging the power storage device by the charging device when charging the power storage device is determined as being possible, and prohibiting charging the power storage device by the charging device when charging the power storage device is determined as not being possible.

2. The method according to claim 1,

wherein, in (c),

prior to charging of the power storage device by the charging device being started, when the value indicating the state of the storage battery received by at least one of the charging device and the power storage device has changed by less than a threshold value compared to the value indicating the past state of the storage battery, charging the power storage device is determined as being possible, and

prior to charging of the power storage device by the charging device being started, when the value indicating the state of the storage battery received by at least one of the charging device and the power storage device has changed by equal to or greater than the threshold value compared to the value indicating the past state of the storage battery, charging the power storage device is determined as not being possible.

3. The method according to claim 1,

wherein, in (c),

prior to charging of the power storage device by the charging device being started, when the value indicating the state of the storage battery received by at least one of the charging device and the power storage device has changed by equal to or greater than a threshold value compared to the value indicating the past state of the storage battery, charging the power storage device is determined as being possible, and

prior to charging of the power storage device by the charging device being started, when the value indicating the state of the storage battery received by at least one of the charging device and the power storage device has changed by less than the threshold value compared to the value indicating the past state of the storage battery, charging the power storage device is determined as not being possible.

4. The method according to claim 3,

wherein, prior to charging of the power storage device by the charging device being started, the value indicating the state of the storage battery received by at least one of the charging device and the power storage device is a capacity of the storage battery from prior to charging of the power storage device by the charging device being started, and the value indicating the past state of the storage battery is a capacity from when charging of the storage battery has been completed in the past.

5. A server device, comprising:

a receiver that receives identification information of a power storage device that is connected to a charging device, and a value indicating a state of a storage battery included in the power storage device, from at least one of the charging device and the power storage device;

a storage that associates to each other and stores the identification information of the power storage device and a history of the value indicating the state of the storage battery;

a determiner that determines a possibility of charging the power storage device by comparing the value indicating the state of the storage battery received by the receiver with a value indicating a past state of the storage battery that corresponds to the identification information of the power storage device received by the receiver and is stored in the storage; and

a transmitter that transmits information indicating the possibility of charging the power storage device determined by the determiner to at least one of the charging device and the power storage device

wherein the determiner permits charging the power storage device by the charging device when charging the power storage device is determined as being possible, and the determiner prohibits charging the power storage device by the charging device when charging the power storage device is determined as not being possible.
