Next, a state of the detachable battery 14 stored in the charging station 16 will be described.
[Expected Value and Number of Batteries for use]
Next, an expected value and the number of batteries for use will be described.
In
In the example of reference sign g111, an expected value from 0:00 to 1:00 is three, an expected value from 1:00 to 2:00 is two, an expected value from 2:00 to 3:00 is zero, and so on.
The expected value calculation unit 1832 calculates the expected value of the number of batteries for use for each time period on the basis of the lending date/time information received when the weather is sunny. The expected value calculation unit 1832 may obtain, for example, an average value of the detachable battery 14 lent from 0:00 to 1:00 on a sunny day and calculate the obtained average value as the expected value.

The use number estimation unit 1833 may estimate the number of batteries for use from 0:00 to 7:00 by obtaining an average value of, for example, an expected value from 0:00 to 1:00, an expected value from 1:00 to 2:00, an expected value from 2:00 to 3:00, an expected value from 4:00 to 5:00, and an expected value from 5:00 to 6:00, and an expected value from 6:00 to 7:00. The use number estimation unit 1833 may estimate a maximum value of expected values in a time period being obtained as the number of batteries for use.
The example shown in
The example shown in
Next, preparation processing performed by the charging station 16 and the management server 18 will be described.
(Step L1) A user visits the charging station 16 and starts replacement work of the detachable battery 14.
(Step S1) After the user returns the detachable battery 14, the control unit 167 of the charging station 16 lends the charged detachable battery 14 to the user.
(Step S2) The control unit 167 of the charging station 16 transmits lending date/time information, which is a date and time at the time of the lending, and a station ID to the management server 18 using the communication unit 165.
(Step S3) The control unit 183 of the management server 18 receives the lending date/time information and the station ID transmitted from the charging station 16 and stores the received lending date/time information and station ID in the storage unit 182. Next, the control unit 183 acquires local weather information at the time of the lent date and time from the Internet or the like by the communication unit 181 via the network NW on the basis of the lending date/time information and the station ID.
(Step S4) The expected value calculation unit 1832 of the management server 18 calculates an expected value of the number of replacement batteries for each time period for each day of the week and weather type on the basis of the lending date/time information received from the charging station 16 and the acquired weather information and then stores the calculated expected value in the storage unit 182.
(Step S5) The use number estimation unit 1833 of the management server 18 estimates the number of batteries (number of batteries for use) to be prepared for each time period for each day of the week and weather type according to the expected value of the number of replacement batteries for each time period for each day of the week and weather type stored in the storage unit 182.
(Step S6) The use number estimation unit 1833 of the management server 18 transmits the number of batteries (number of batteries for use) to be prepared for each estimated time period to the charging station 16 by the communication unit 181.
(Step L2) The replacement work of the detachable battery 14 ends. In the example shown in
Next, charging determination processing performed by the charging station 16 will be described.
(Step S11) When the detachable battery 14 is connected to the connection part 164, the control unit 167 of the charging station 16 determines that the detachable battery 14 has been returned.
(Step S12) The control unit 167 reads the number of batteries for use in a time period corresponding to the returned time from the storage unit 166. Next, the control unit 167 determines whether or not the number of fully charged batteries in the charging station is larger than the number of batteries for use. When the control unit 167 determines that the number of fully charged batteries in the charging station is larger than the number of batteries for use (step S12; YES), the control unit 167 proceeds to processing of step S13. When the control unit 167 determines that the number of fully charged batteries in the charging station is not larger than the number of batteries for use (step S12; NO), the control unit 167 proceeds to processing of step S14.
(Step S13) The control unit 167 does not perform charging of the returned detachable battery 14. The control unit 167 ends the processing.
(Step S14) The control unit 167 performs charging of the returned detachable battery 14. That is, the control unit 167 determines the number of batteries to be charged among the plurality of batteries on the basis of the number of batteries for use and charges a determined number of batteries. Alternatively, the control unit 167 may determine the number of batteries that are not charged among the plurality of batteries on the basis of the number of batteries for use. The control unit 167 ends the processing.
The control unit 167 performs the processing of steps S12, S13, and S14 every predetermined time (for example, 10 minutes). Therefore, when the fully charged batteries for use are used, the control unit 167 also performs charging of the batteries for deterioration suppression.
In
Specifically, for example, when the number of batteries for use is six and the present number of fully charged batteries is four, if a plurality of detachable batteries 14 are returned, the control unit 167 performs charging of two of them and does not perform charging of the remaining two.
An example in which the management server 18 transmits the number of batteries for use to the charging station 16 has been described in the above-described example, but the present invention is not limited thereto. The management server 18 may transmit the number of batteries for deterioration suppression stored in a low SOC state without being charged to the charging station 16. Alternatively, the management server 18 may transmit proportions of the number of batteries for use and the number of batteries for deterioration suppression to the charging station 16.
An example in which the management server 18 estimates the number of batteries for use for each charging station has been described in the above-described example, but the present invention is not limited thereto. The management server 18 may estimate the number of batteries for use for a plurality of charging stations 16 included in a predetermined range.
An example in which the management server 18 acquires weather information has been described in the above-described example, but the present invention is not limited thereto. The charging station 16 may acquire weather information from the Internet via the network NW and the weather information may be added to the lending date/time information and the station ID to be transmitted to the management server 18.
As described above, in the present embodiment, the management server 18 controls the SOC of the detachable battery 14 so that deterioration suppression is possible on the basis of a date and time when the detachable battery 14 is lent and weather type at the lent location, that is, on the basis of usage information of the detachable battery 14 of the user. That is, the management server 18 determines proportions of the battery for use and the battery for deterioration suppression from usage state data of the user. Then, the charging station 16 prepares fully charged batteries for use and stores batteries other than the fully charged batteries for use in a low SOC state for deterioration suppression according to the control of the management server 18. Then, when the batteries for use are used, the charging station 16 also charges the batteries for deterioration suppression.
Thereby, according to the present embodiment, the SOC for optimum storage can also be adjusted according to the usage state of the user. Also, according to the present embodiment, deterioration of the battery is suppressed and the battery can be used for a long period of time compared to a case in which charging is started at the moment when the battery is loaded in the charging station 16.
An example in which the management server 18 performs calculation of the expected value and estimation of the number of batteries for use has been described in the above-described example, but processing for these may be performed by the charging station 16.
