[Overview of Battery Management System 100]
An outline of the battery management system 100 will be described with reference to FIGS. 1 and 2. FIG. 1 schematically shows an example of the system configuration of the battery management system 100. FIG. 2 schematically shows an example of the correlation between the capacity deterioration coefficient and the charge rate [%].

As shown in FIG. 1, in the present embodiment, the battery management system 100 includes a management server 120 and a battery station 140. In this embodiment, the battery station 140 holds one or more (sometimes referred to as one or more) batteries 20. The battery management system 100 may include one or more battery stations 140.

In the present embodiment, the management server 120 and the battery station 140 can send and receive information to and from each other via the communication network 10. In the present embodiment, the management server 120 can send and receive information to and from the communication terminal 32 of the user 30 via the communication network 10.

In the present embodiment, the details of the battery management system 100 will be described by exemplifying the case where the battery management system 100 provides one or more batteries 20 to the user 30. The battery management system 100 may provide one or more batteries 20 to each of one or more users 30.

For example, the user 30 requests the battery management system 100 to rent out the battery 20 held in the specific battery station 140 by using the communication terminal 32. The battery management system 100 executes a process for lending the battery 20 to the user 30 in response to the lending request. In the present embodiment, the user 30 uses the battery 20 lent out from the battery management system 100 as a power source for the electric motorcycle 34.

By the way, while the battery 20 is repeatedly used, the deterioration of the battery 20 progresses. Therefore, in the present embodiment, the administrator of the battery 20 (not shown) collects the battery 20 deteriorated from the predetermined management standard from the battery station 140, and transfers the new battery 20 to the battery station 140. Introduce. Thereby, the distribution of the battery 20 can be controlled so that the battery 20 having an appropriate charge / discharge performance is distributed.

In this embodiment, the battery management system 100 manages the use of one or more batteries 20 respectively. For example, the battery management system 100 is a lending state (for example, rentable, unrentable, renting, etc.) and an operating state (for example, charging, discharging, waiting, etc.) of one or more batteries 20. ), Charge state (for example, current SOC), storage state (for example, temperature, humidity, etc.), deterioration state, and the like. The form of providing the battery 20 is not limited to lending.

In the present embodiment, the battery management system 100 preferentially determines the battery 20 to be provided to the user 30 based on the capacity deterioration coefficient shown in FIG. As described above, FIG. 2 schematically shows an example of the correlation between the capacity deterioration coefficient and the charge rate [%]. In the present embodiment, the capacity deterioration coefficient [Ah / h] is per unit time of the full charge capacity [Ah] of the battery 20 when the battery 20 is left in a state where the charge rate of the battery 20 is kept constant. Indicates the amount of decrease in. In the present embodiment, the charge rate is defined as 100% in the fully charged state and 0% in the fully discharged state. The charge rate may be referred to as State Of Charge (SOC), charge state, or the like.

As shown in FIG. 2, when the capacity deterioration coefficient is plotted with the charge rate on the horizontal axis and the capacity deterioration coefficient on the vertical axis, a curve 200 having a downwardly convex shape appears. Therefore, in order to suppress the deterioration of the battery 20 during the storage period of the battery 20, the charge rate of the battery 20 may be adjusted so that the capacity deterioration coefficient becomes kth or less before the battery 20 is stored. preferable. The region where the capacitance deterioration coefficient is kth or less may be referred to as an intermediate region.

However, the battery 20 to be rented is stored in a state of high charge rate until it is provided to the user 30. Therefore, for example, the battery 20 whose capacity deterioration coefficient is within the range of the intermediate region and the battery 20 whose capacity deterioration coefficient is outside the range of the intermediate region are selected as lending targets, and then the selected battery 20 is selected. By selecting the battery 20 whose capacity deterioration coefficient is out of the range of the intermediate region as the loan target, the deterioration of the battery 20 as a whole is suppressed. Further, when charging the selected battery 20 after selecting one of the two batteries 20 whose capacity deterioration coefficient is out of the range of the intermediate region as the loan target, the battery 20 having a larger capacity deterioration coefficient is lent out. By selecting the target, deterioration of the battery 20 as a whole is suppressed.

According to one embodiment, when the battery management system 100 has to charge at least one of the two batteries 20 in preparation for lending to the user 30, the battery management system 100 has a battery management system 100. Determine how to charge each battery, taking into account the capacity degradation factor of each battery. According to another embodiment, when the battery management system 100 has to charge the battery 20 of either of the two batteries 20 in preparation for lending to the user 30, the battery management system 100 Determines which battery 20 to charge in consideration of the capacity deterioration coefficient of each battery.

For example, the battery station 140 holds five batteries 20, of which the SOC of three batteries 20 is 100% and the SOC of one battery 20 is 20%. Consider the case where the SOC of one battery 20 is 80%. In this case, when it is necessary to set the SOC of the four batteries 20 to 100% in preparation for lending to one or more users 30, the battery station 140 takes into consideration the capacity deterioration coefficient of each battery. Determine how to charge the battery 20 with 20% SOC and the battery 20 with 80% SOC.

More specifically, the battery station 140 determines the charging method described above so that the charging speed of one of the battery 20 having a 20% SOC and the battery 20 having an SOC of 80% is higher than the charging speed of the other. To do. The battery station 140 may decide to charge one of the 20% SOC battery 20 and the 80% SOC battery 20 and not the other.

According to the example described in FIG. 2, the value of the capacity deterioration coefficient (k2) when the SOC is 80% is larger than the value (k1) of the capacity deterioration coefficient when the SOC is 20%. Therefore, the battery station 140 determines, for example, to charge both batteries so that the charging speed of the battery 20 having an SOC of 80% is higher than the charging speed of the battery 20 having an SOC of 20%. The charging speed of the battery 20 having a SOC of 20% may be 0. That is, the battery station 140 may decide that the SOC charges the 80% battery 20 and the SOC does not charge the 20% battery 20. As a result, the charging speed of the battery 20 having an SOC of 80% is held by the battery station 140 as compared with the case where both are charged so that the charging speed of the battery 20 having an SOC of 20% is smaller than the charging speed of the battery 20 having an SOC of 20%. Deterioration of the batteries 20 as a whole is suppressed.

In the present embodiment, the priority determination unit 524 preferentially lends or charges the battery 20 having a large capacity deterioration coefficient to the battery 20 having a small capacity deterioration coefficient among the plurality of batteries 20 held by the battery station 140. Prioritize each battery to be targeted. For example, the priority determination unit 524 determines the priority of each of the plurality of batteries 20 so that the higher the capacity deterioration coefficient of the battery 20, the higher the priority.

By determining the priority as described above, the increase in the amount of power stored in the battery 20 having a large capacity deterioration coefficient in the battery station 140 increases the amount of power stored in the battery 20 having a small capacity deterioration coefficient. It may be determined to charge the plurality of batteries 20 so that they are greater than the quantity. Further, the charging operation of the battery station 140 is performed so that the increase in the amount of power stored in the battery 20 having a large capacity deterioration coefficient is larger than the increase in the amount of power stored in the battery 20 having a small capacity deterioration coefficient. Can be controlled.

In the priority order determination unit 524, the priority of the battery 20 whose SOC value is outside the predetermined numerical range is the priority of the battery 20 whose SOC value is within the predetermined numerical range. The priority of each of the plurality of batteries 20 may be determined so as to be higher than the order. The above numerical range may be a numerical range corresponding to the intermediate region described in FIG.

When the number of batteries 20 whose SOC value is outside the predetermined numerical range is 2 or more, the priority determination unit 524 may determine the priority among these batteries 20. The priorities of the batteries 20 may be the same. When the number of batteries 20 whose SOC value is within a predetermined numerical range is 2 or more, the priority determination unit 524 may set the priority of these batteries 20 to the same, and these batteries 20 may be the same. You may decide the priority between.

For example, when the number of batteries 20 whose SOC value is outside the predetermined numerical range is 2 or more, the priority determination unit 524 determines the priority among these batteries 20. On the other hand, when the number of batteries 20 whose SOC value is within a predetermined numerical range is 2 or more, the priority determination unit 524 sets the priority of these batteries 20 to the same. As a result, the priority determination unit 524 can reduce the amount of calculation without significantly affecting the deterioration suppressing effect of the battery 20.

In the present embodiment, the charging target determination unit 526 is a battery 20 (referred to as a charging target) to be charged in a specific period among one or more batteries 20 housed in the battery storage chamber 422 of one or more charging units 420. May be done). For example, the charging target determination unit 526 of each battery station acquires a charging schedule for the battery station from the battery management unit 320 of the management server 120. Further, the charging target determination unit 526 of each battery station acquires information indicating the charging state of one or more batteries 20 held by each battery station from the condition monitoring unit 522 of each battery station. The charging target determination unit 526 determines the battery 20 to be charged in a specific period based on the charging schedule and the charging state of the battery 20.

At this time, the charge target determination unit 526 may determine the battery 20 to be charged in consideration of the priority determined by the priority order determination unit 524. The charging target determination unit 526 may preferentially select the battery 20 having the higher priority as the charging target. The charging target determination unit 526 may decide to charge the battery 20 having a higher priority and not to charge the battery 20 having a lower priority.

As described above, in the priority determination unit 524, among the plurality of batteries 20 held by the battery station 140, the battery 20 having a large capacity deterioration coefficient is preferentially lent or charged over the battery 20 having a small capacity deterioration coefficient. Prioritize each battery to be targeted. Therefore, the charging target determination unit 526 determines the battery 20 to be charged in consideration of the priority determined by the priority determination unit 524, so that the battery 20 among the two batteries 20 held in the battery station 140 is determined. At least one of the above two batteries 20 is used so that the amount of increase in the amount of power stored in the battery 20 having a large capacity deterioration coefficient is larger than the amount of increase in the amount of power stored in the other battery 20. It is decided to charge. The charging target determination unit 526 may decide to charge the battery 20 having the larger capacity deterioration coefficient among the above two batteries 20 and not to charge the other battery 20.

More specifically, the charging target determination unit 526 determines the battery 20 to be charged according to the following procedure. First, the charging target determination unit 526 determines the number Ns of the number of batteries 20 that the battery station 140 should complete charging by a specific time based on the charging schedule. Further, the charging target determination unit 526 determines the number Nc of the batteries 20 that have already been charged based on the respective charging states of one or more batteries 20 held by the battery station 140. Whether or not the charging of the battery 20 is completed may be determined by, for example, whether or not the charging rate of the battery 20 is larger than a specific value.

Next, the charging target determination unit 526 determines whether or not there is a battery 20 to be charged by the battery station 140 up to the above-mentioned specific time based on Ns and Nc. When the battery station 140 determines that there is a battery 20 to be charged in the period up to the specific time, the charging target determination unit 526 calculates the difference between Ns and Nc, so that the battery station 140 is described as described above. The number of batteries 20 to be charged in the period up to a specific time is determined. As a result, the number Nt of the batteries 20 to be charged is determined.

Next, the charging target determination unit 526 selects the battery 20 to be charged from among the plurality of batteries 20 held by the battery station 140 that have not been fully charged. For example, the charging target determination unit 526 extracts the number of batteries 20 matching the above number Nt in order from the batteries 20 having the largest capacity deterioration coefficient from the batteries 20 that have not been charged. The charging target determination unit 526 selects the extracted battery 20 as a charging target.

After that, the charge target determination unit 526 transmits the identification information of the battery 20 selected as the charge target to the charge / discharge control unit 444. The charging target determination unit 526 may transmit a signal for starting charging of the battery 20 selected as the charging target to the charge / discharge control unit 444. As a result, charging of the battery 20 selected as the charging target is started. On the other hand, charging of the battery 20 not selected as the charging target is not started. As a result, the battery station 140 so that the amount of increase in the amount of power stored in the battery 20 selected as the charging target is larger than the amount of increase in the amount of power stored in the battery 20 not selected as the charging target. A plurality of batteries 20 held in the battery 20 are charged.

As described above, according to the present embodiment, the capacity deterioration coefficient of the battery 20 selected as the charging target is larger than the capacity deterioration coefficient of the battery 20 not selected as the charging target. Therefore, at the time when charging is completed, the battery station 140 has, for example, a fully charged battery 20 and a battery 20 having a relatively small capacity deterioration coefficient. As a result, the total of the capacity deterioration coefficients of the plurality of batteries 20 held by the battery station 140 becomes relatively small. Further, the total SOC of the plurality of batteries 20 held by the battery station 140 becomes relatively small. As a result, deterioration of the plurality of batteries 20 held by the battery station 140 as a whole is suppressed.

The priority determination unit 524 may be an example of a control device and a control unit. The charging target determination unit 526 may be an example of a control device and a control unit.

The information indicating the charging state of the battery 20 may be an example of the information indicating the amount of electric power stored in the battery 20. The charging schedule may be an example of information indicating the number of power storage devices to be charged. The battery 20 selected as the charging target by the charging target determining unit 526 may be an example of the first power storage device. The battery 20 not selected as the charging target by the charging target determining unit 526 may be an example of the second power storage device.

In the present embodiment, the condition monitoring unit 522 acquires information indicating the amount of electric power stored in each of the one or a plurality of batteries 20 held by the battery station 140, and based on the information, the capacity of each battery. The details of the loan management unit 446 have been described by taking the case of determining the deterioration coefficient as an example. However, the loan management unit 446 is not limited to this embodiment. In another embodiment, the priority determination unit 524 acquires information indicating the amount of electric power stored in each of the one or a plurality of batteries 20 held by the battery station 140, and based on the information, of each battery. The capacitance degradation coefficient may be determined.

Next, an example of the management method by the battery management system 100 will be described with reference to FIGS. 6, 7, and 8. FIG. 6 schematically shows an example of a flowchart of a management method by the battery management system 100. 7 and 8 schematically show an example of SOC fluctuations of the batteries 720 and 740 stored in the battery station 140. FIG. 7 shows an example of variations in SOC of the battery 720 and the battery 740 when the battery 720 is charged. FIG. 8 shows an example of variations in SOC of the battery 720 and the battery 740 when the battery 740 is charged.

As shown in FIG. 6, according to the present embodiment, for example, in step 622 (step may be abbreviated as S), the battery management unit 320 of the management server 120 determines the battery in a specific period. Forecast 20 demands. The battery management unit 320 may predict the demand for the battery 20 for each battery station 140. The battery management unit 320 forecasts the demand for the battery 20 for each battery station 140 in consideration of, for example, the past demand record and the current reservation status.

Next, in S624, the battery management unit 320 creates a charging schedule for each battery station 140 based on the demand forecast obtained in S622. The battery management unit 320 transmits to each battery station information indicating the charging schedule at the battery station.

Next, in S626, the rental management unit 446 of each battery station determines the battery 20 to be charged at the battery station. At this time, the lending management unit 446 preferentially selects the battery 20 having a large capacity deterioration coefficient as the charging target among the batteries 20 that have not been charged. The lending management unit 446 may preferentially select a battery 20 having a large SOC as a charging target among the batteries 20 that have not been charged.

After that, the rental management unit 446 of each battery station transmits the identification information of the battery 20 selected as the charging target to the charge / discharge control unit 444 of the battery station. The charge / discharge control unit 444 of each battery station controls the charging circuit 426 of the battery station to charge the battery 20 to be charged.

An example of the deterioration suppressing effect when the lending management unit 446 determines the battery 20 to be charged will be described with reference to FIGS. 7 and 8. In FIGS. 7 and 8, either the battery 720 or the battery 740, which has not been fully charged, is selected as the charging target. In FIGS. 7 and 8, the time t1 represents the charging start time, and the time t2 represents the charging end time.

As shown in FIGS. 7 and 8, at time t1, the SOC of the battery 720 is 20% and the SOC of the battery 740 is 80%. As described in connection with FIG. 2, the capacitance degradation coefficient when the SOC is 20% is k1, the capacitance degradation coefficient when the SOC is 80% is k2, and k2 is larger than k1. The capacity deterioration coefficient when fully charged is kf (however, kf is larger than k2).

As shown in FIG. 7, when the battery 720 is selected as the charging target, the total of the capacity deterioration coefficients of the battery 720 and the battery 740 is kf + k2. Further, the total SOC of the battery 720 and the battery 740 in this case is 180%.

On the other hand, as shown in FIG. 8, when the battery 740 is selected as the charging target, the total of the capacity deterioration coefficients of the battery 720 and the battery 740 is k1 + kf. Further, the total SOC of the battery 720 and the battery 740 in this case is 120%.

As described above, since k2 is larger than k1, when the battery 740 is selected as the charging target, the total capacity deterioration coefficient of the battery 720 and the battery 740 is compared with the case where the battery 720 is selected as the charging target. Becomes smaller. That is, deterioration of the battery 720 and the battery 740 as a whole is suppressed.

The battery 720 may be an example of one of the first power storage device and the second power storage device. The battery 740 may be another example of the first power storage device and the second power storage device.
