However, the electric vehicle management system 100 may be realized by cloud computing. FIG. 2 is a block diagram showing the electric vehicle management system 100. As shown in FIG. As shown in FIG. 2 , the electric vehicle management system 100 includes a base terminal 20 and a management server 30 .

The base terminal 20 is a terminal installed at each base H1 (see FIG. 1), and is a terminal used by an administrator or the like of each base H1. The base terminal 20 may be, for example, a desktop-type or laptop-type personal computer used by an administrator, or may be a smart phone or a tablet terminal. The base terminal 20 includes a screen 21 , input means 22 such as a keyboard, mouse or touch panel operated by an administrator to input data, and a terminal control device 23 . The terminal control device 23 is communicably connected to the screen 21 and the input means 22 .

The management server 30 is communicably connected to the base terminal 20 . In addition, the management server 30 is communicably connected to the electric vehicle 10 managed at each site H1. The management server 30 may be implemented by a single computer, or may be implemented by a plurality of computers working together. The management server 30 has a control device 33 . Although not shown, the management server 30 may be provided with a screen and an input means like the base terminal 20 .

The configuration of the control device 33 is not particularly limited. Here, the control device 33 is, for example, a microcomputer. The control device 33 includes, for example, an I/F, a CPU, a ROM, and a RAM. In this embodiment, as shown in FIG. 2, the control device 33 includes a storage section 50, a first communication section 51, and a second communication section 52. As shown in FIG.

FIG. 3 is a diagram showing temperatures, temperature changes, and the frequency of use of the electric vehicle 10 in the first use area A11 to the third use area A13. By the way, in the present embodiment, as shown in FIG. 3, the environment such as the temperature and the usage conditions of the electric vehicle 10 differ for each usage area A1. Therefore, the degree of deterioration R1 (see FIG. 4) of the battery 5 mounted on the electric vehicle 10 may vary due to the different use areas A1. For example, in the example of FIG. 3, in the second use area A12, the temperature change is large in a predetermined period (for example, one day) in a high temperature area. Further, in the second use area A12, the frequency of use of the electric vehicle 10 is high, and the frequency of charging and discharging of the battery 5 is high. Therefore, in the second electric vehicle 12 used in the second use area A12, the battery 5 is easily deteriorated, and the degree of deterioration R1 of the battery 5 is relatively high. On the other hand, the third use area A13 is in a low temperature area and the temperature change during the predetermined period is small. In addition, in the third use area A13, the frequency of use of the electric vehicle 10 is low, the frequency of charging and discharging of the battery 5 is low, and the distance traveled at one time tends to be long. Therefore, in the third electric vehicle 13 used in the third use area A13, the battery 5 is less likely to deteriorate, and the degree of deterioration R1 of the battery 5 is relatively low. Note that the first use area A11 is a medium temperature region, and the temperature change during a predetermined period is smaller than that of the second use area A12 and larger than that of the third use area A13. Also, in the first use area A11, the frequency of use of the electric vehicle 10 is lower than in the second use area A12, and the frequency of use of the electric vehicle 10 is higher than in the third use area A13. Therefore, the battery 5 of the first electric vehicle 11 used in the first use area A11 is less likely to deteriorate than the second electric vehicle 12 and more easily deteriorated than the third electric vehicle 13 .

In the present embodiment, it is possible that the degree of deterioration R1 of the battery 5 of the electric vehicle 10 varies from one base H1 (see FIG. 1) to another due to the different use areas A1. Therefore, in the present embodiment, the electric vehicle management system 100 notifies a recommendation to change the use area A1 of the electric vehicle 10 according to the degree of deterioration R1 of the battery 5 mounted on the electric vehicle 10 . For example, the rental car company receives this notification and changes the usage area A1 of the electric vehicle 10 to another usage area A1 with a different environment etc. according to the degree of deterioration R1 of the battery 5. The rate of deterioration of the battery 5 can be adjusted.

Next, a procedure for changing the use area A1 in the electric vehicle 10 will be described with reference to the flowchart of FIG.

First, at step S101 in FIG. 4, the use area information acquisition unit 61 in FIG. 2 acquires the use area information D1. The use area information D1 is information indicating which electric vehicle 10 is mainly used in which use area A1, and the electric vehicle 10 and the use area A1 of the electric vehicle 10 are linked. (or associated) information. In other words, the use area information D1 is information indicating which electric vehicle 10 is managed at which base H1, and also information indicating at which storage location P1 it is stored.

Here, as shown in FIG. 2, the use area information acquisition unit 61 acquires the use area information D1 from the base terminal 20 of each base H1. The terminal control device 23 of the base terminal 20 stores the use area information D1 in the use area A1 of the base H1. The use area information acquisition unit 61 acquires the use area information D1 from the terminal control device 23 of the base terminal 20 via the first communication unit 51 . The use area information D1 acquired by the use area information acquisition unit 61 is stored in the storage unit 50. FIG.

Next, in step S102 of FIG. 4, the vehicle information acquisition unit 63 of FIG. 2 acquires the vehicle information D2 of the electric vehicle 10. FIG. Here, the vehicle information D2 is information about the electric vehicle 10 managed at each base H1. Vehicle information D<b>2 includes at least deterioration degree R<b>1 of battery 5 mounted on electric vehicle 10 . In this embodiment, the vehicle information D2 includes, in addition to the degree of deterioration R1 of the battery 5, the model year of the electric vehicle 10, the mileage of the electric vehicle 10, the model of the electric vehicle 10, and the color of the vehicle body of the electric vehicle 10. , the battery capacity of the battery 5 (for example, the distance that can be traveled using the battery 5), the usage period of the electric vehicle 10, and the like.

Here, the deterioration degree R1 of the battery 5 indicates the degree of deterioration of the battery 5 . The degree of deterioration R1 of the battery 5 increases according to the usage environment and method of use of the electric vehicle 10 and the age of the battery 5 . As the battery 5 deteriorates, the deterioration degree R1 of the battery 5 increases, and as the battery 5 does not deteriorate, the deterioration degree R1 of the battery 5 decreases. The method for calculating the degree of deterioration R1 of the battery 5 is not particularly limited, and the degree of deterioration R1 of the battery 5 can be calculated using a conventional method. For example, the deterioration degree R1 of the battery 5 can be calculated based on the internal resistance value of the battery 5 . The degree of deterioration R1 of the battery 5 may be the capacity maintenance rate of the battery 5 or the travelable distance of the electric vehicle 10 when the battery 5 is fully charged. The model year of the electric vehicle 10 refers to the year in which the electric vehicle 10 was manufactured. The mileage of the electric vehicle 10 is, for example, the total mileage since it was manufactured. The electric vehicle 10 is usually equipped with a battery assembly (for example, an assembled battery) in which a plurality of single batteries are connected in parallel and/or in series. Therefore, the battery 5 here means a battery assembly (for example, an assembled battery) in which a plurality of single batteries are connected in parallel and/or in series. The degree of deterioration R1 of the battery 5 means the degree of deterioration of the battery assembly.

In this embodiment, as shown in FIG. 2 , the vehicle information acquisition unit 63 acquires vehicle information D2 from the electric vehicle 10 . Here, the vehicle information D2 of the electric vehicle 10 is stored in the electric vehicle 10 . Vehicle information acquisition unit 63 acquires vehicle information D<b>2 from electric vehicle 10 via second communication unit 52 . However, the vehicle information D<b>2 may be stored in the terminal control device 23 of the base terminal 20 . In this case, the vehicle information acquisition section 63 may acquire the vehicle information D2 from the base terminal 20 via the first communication section 51 .

In this embodiment, as shown in FIG. 2, the vehicle information acquisition section 63 has a first vehicle information acquisition section 63A, a second vehicle information acquisition section 63B, and a third vehicle information acquisition section 63C. . FIG. 5 is a conceptual diagram showing acquisition of vehicle information D2. Here, among the vehicle information D2, the vehicle information D2 relating to the first electric vehicle 11 used in the first use area A11 is referred to as first vehicle information D21 (see FIG. 5), and is used in the second use area A12. The vehicle information D2 related to the second electric vehicle 12 that is obtained is referred to as second vehicle information D22 (see FIG. 5). Further, the vehicle information D2 regarding the third electric vehicle 13 used in the third use area A13 is referred to as third vehicle information D23 (see FIG. 5). As shown in FIG. 5 , the first vehicle information D<b>21 includes at least a first deterioration degree R<b>11 that is the deterioration degree R<b>1 of the battery 5 mounted on the first electric vehicle 11 . The second vehicle information D<b>22 includes at least a second deterioration degree R<b>12 that is the deterioration degree R<b>1 of the battery 5 mounted on the second electric vehicle 12 . The third vehicle information D<b>23 includes at least a third deterioration degree R<b>13 that is the deterioration degree R<b>1 of the battery 5 mounted on the third electric vehicle 13 .

The first vehicle information acquisition unit 63A in FIG. 2 acquires the first vehicle information D21 from the base terminal 20 at the first base H11 or the first electric vehicle 11 . The second vehicle information acquisition unit 63B in FIG. 2 acquires the second vehicle information D22 from the base terminal 20 at the second base H12 or the second electric vehicle 12. FIG. The third vehicle information acquisition unit 63C in FIG. 2 acquires the third vehicle information D23 from the base terminal 20 at the third base H13 or the third electric vehicle 13. FIG. The vehicle information D2 (for example, the first vehicle information D21 to the third vehicle information D23) acquired by the vehicle information acquisition unit 63 (the first vehicle information acquisition unit 63A to the third vehicle information acquisition unit 63C) is stored in the storage unit 50. stored in Also, the vehicle information D2 may be acquired by the vehicle information acquisition unit 63 before the use area information D1.

Next, at step S103 in FIG. 4, the comparison unit 65 in FIG. 2 compares the deterioration degree R1 of the battery 5 included in the vehicle information D2 with a predetermined reference deterioration degree ND1. The reference deterioration degree ND1 is stored in the storage unit 50 in advance. For example, the comparison unit 65 determines whether the deterioration degree R1 of the battery 5 in each electric vehicle 10 is lower than the reference deterioration degree ND1. The comparison unit 65 compares a first deterioration degree R11 of the battery 5 of the first electric vehicle 11, a second deterioration degree R12 of the battery 5 of the second electric vehicle 12, and a third deterioration degree of the battery 5 of the third electric vehicle 13. R13 is compared with the standard deterioration degree ND1.

The reference deterioration degree ND1 may be set to a common value for each electric vehicle 10, but in the present embodiment, the reference deterioration degree ND1 is set to a value for each electric vehicle 10. FIG. For example, the reference deterioration degree ND1 has a first reference deterioration degree for the first electric vehicle 11, a second reference deterioration degree for the second electric vehicle 12, and a third reference deterioration degree for the third electric vehicle 13. . The comparison unit 65 compares the first deterioration degree R11 with the first reference deterioration degree, compares the second deterioration degree R12 with the second reference deterioration degree, and compares the third deterioration degree R13 with the third reference deterioration degree. do. Specifically, the comparison unit 65 determines whether the first deterioration degree R11 is lower than the first reference deterioration degree, and determines whether the second deterioration degree R12 is lower than the second reference deterioration degree. Then, it is determined whether or not the third deterioration degree R13 is lower than the third reference deterioration degree.

Next, in step S104 in FIG. 4, the notification unit 67 in FIG. 2 notifies a recommendation to change the use area A1 of the electric vehicle 10 based on the result of the comparison by the comparison unit 65. FIG. For example, when the comparison unit 65 determines that the deterioration degree R1 of the battery 5 of the electric vehicle 10 is higher than the reference deterioration degree ND1 (here, the first reference deterioration degree), the battery 5 is deteriorated. By changing the use area A1 of 10 to a use area A1 that is less likely to deteriorate, the rate of deterioration of the battery 5 can be suppressed. In such a case, the notification unit 67 makes a notification recommending that the use area A1 of the electric vehicle 10 be changed. For example, when the comparison unit 65 determines that the second deterioration degree R12 of the battery 5 of the second electric vehicle 12 is higher than the reference deterioration degree ND1 (here, the second reference deterioration degree), the notification unit 67 A notification to recommend changing the use area A1 of the electric vehicle 12 from the second use area A12 to the first use area A11 in which the rate of deterioration of the battery 5 is suppressed more than in the second use area A12 is provided.

Here, the change of the use area A1 of the electric vehicle 10 can be achieved, for example, by changing the storage location P1 (see FIG. 1) of the electric vehicle 10, or a site H1 (see FIG. 1) that manages the electric vehicle 10. 1) can be achieved by changing Therefore, the notification unit 67 may make a notification to recommend changing the storage location P1 of the electric vehicle 10 based on the result of the comparison by the comparison unit 65, or to change the location H1 of the electric vehicle 10. may be notified to recommend

For example, the notification unit 67 may display on the screen 21 (see FIG. 2) of the base terminal 20 a message recommending that the use area A1 of the corresponding electric vehicle 10 be changed. Further, the notification unit 67 may send an e-mail to the base terminal 20 recommending that the use area A1 of the corresponding electric vehicle 10 be changed. When notified by the notification unit 67, the relevant electric vehicle 10 is moved to the storage location P1 in the changed use area A1, and information on the use area A1 linked to the electric vehicle 10 in the use area information D1 is displayed. to update.

In the above description, it is notified to recommend changing the use area A1 of the electric vehicle 10 where the deterioration degree R1 of the battery 5 is higher than the reference deterioration degree ND1. A notification recommending replacement of the electric vehicle 10 and the use area A1 may be made. For example, in step S103 of FIG. 4, the comparison unit 65 of FIG. The second deterioration degree R12 (see FIG. 5) is compared with the second reference deterioration degree.

At this time, when the first deterioration degree R11 is lower than the first reference deterioration degree and the second deterioration degree R12 is higher than the second reference deterioration degree, or when the first deterioration degree R11 is higher than the first reference deterioration degree is higher and the second deterioration degree R12 is lower than the second reference deterioration degree, in step S104 of FIG.

Specifically, the notification unit 67 recommends changing the use area A1 of the first electric vehicle 11 to the second use area A12 and changing the use area A1 of the second electric vehicle 12 to the first use area A11. to be notified. At this time, the notification unit 67 may issue a notification recommending that the storage location P1 of the first electric vehicle 11 and the second electric vehicle 12 be exchanged, or may issue a notification recommending that the base H1 be exchanged. good. Specifically, the notification unit 67 changes the storage location P1 of the first electric vehicle 11 to the second storage location P12 (see FIG. 1), and changes the storage location P1 of the second electric vehicle 12 to the first storage location P11 (see FIG. 1). (See FIG. 1). Further, the notification unit 67 changes the base H1 of the first electric vehicle 11 to the second base H12 (see FIG. 1), and changes the base H1 of the second electric vehicle 12 to the first base H11 (see FIG. 1). You may send a notice recommending that For example, the rental car company replaces the use area A1 of the electric vehicle 10 by receiving the notification recommending this replacement. As a result, for example, the first deterioration degree R11 of the battery 5 of the first electric vehicle 11 and the second deterioration degree R12 of the battery 5 of the second electric vehicle 12 are leveled, and the operator using the electric vehicle management system 100 It is possible to suppress a decrease in the total asset value of the electric vehicle 10 owned by. In this embodiment, for example, by exchanging the storage location P1 or base H1 of each of the first electric vehicle 11 and the second electric vehicle 12, the use area A1 of each of the first electric vehicle 11 and the second electric vehicle 12 can be easily changed. can be replaced with

In the above description, the notification for recommending replacement of the use areas A1 between the first electric vehicle 11 and the second electric vehicle 12 has been described. When the condition that R1 is lower than the reference deterioration degree ND1 and the deterioration degree R1 of the battery 5 of the other electric vehicle 10 is higher than the reference deterioration degree ND1 is satisfied, the use area A1 of the corresponding electric vehicle 10 is replaced. A notice may be issued recommending that Therefore, by satisfying the above conditions, the notification unit 67 may issue a notification recommending that the use areas A1 of the first electric vehicle 11 and the third electric vehicle 13 be switched, A notification recommending replacement of the use area A1 with the third electric vehicle 13 may be provided. Further, it may be notified that the electric vehicle 10 is rotated in three or more use areas A1.

In the above description, the recommendation to change the usage area A1 of the electric vehicle 10 is notified according to the deterioration degree R1 of the battery 5. However, the vehicle information D2 other than the deterioration degree R1 of the battery 5, for example A recommendation to change the use area A1 of the electric vehicle 10 may be notified in consideration of the model year and the mileage of the electric vehicle 10 . For example, in step S103 of FIG. 4, the comparison unit 65 of FIG. 2 compares the deterioration degree R1 of the battery 5 and the model year of the electric vehicle 10, A recommendation to change the usage area A1 of the electric vehicle 10 may be sent according to the degree of deterioration R1 of the battery 5 and the model year of the electric vehicle 10 . For example, a rental car company attaches great importance to the model year of the electric vehicle 10 . Therefore, when the comparison unit 65 determines that the model year of the electric vehicle 10 is older than the predetermined reference model year, or determines that the model year is newer than the reference model year, the notification unit 67 may make a notification to recommend changing the use area A1. In this way, by considering the model year of the electric vehicle 10, the electric vehicle management system 100 according to the present embodiment becomes more effective for a trader or the like who attaches great importance to the model year.

For example, in step S103 of FIG. 4, the comparison unit 65 compares the deterioration degree R1 of the battery 5 and the traveling distance of the electric vehicle 10, and in step S104 of FIG. , a notification recommending that the use area A1 of the electric vehicle 10 be changed may be made according to the mileage of the electric vehicle 10 . For example, when the comparison unit 65 determines that the travel distance of the electric vehicle 10 is shorter than a predetermined reference travel distance, or determines that it is longer than the reference travel distance, the notification unit 67 , a notification recommending that the use area A1 be changed may be sent. In this way, by considering the travel distance of the electric vehicle 10, the electric vehicle management system 100 according to the present embodiment becomes more effective for businesses and the like who place importance on the travel distance.

In the above description, it is assumed that use area A1 of electric vehicle 10 is changed by changing base H1 and storage location P1, so the owner of electric vehicle 10 is not changed. However, the owner of electric vehicle 10 may be changed. For example, the electric vehicle 10 owned by a rental car company may be sold to others, such as other merchants or individuals, according to the vehicle information D2. For example, car rental companies tend to sell older electric vehicles 10, and some other merchants do not attach importance to the model year. Therefore, for example, the comparison unit 65 in FIG. The notification unit 67 may notify that the electric vehicle 10 whose model year is older than the reference model year is recommended to be sold, rented, or leased to another person.

FIG. 6 is a flow chart showing the notification procedure based on the need condition N1. In the electric vehicle management system 100 according to the present embodiment, it is possible to set a need condition N1 (see FIG. 6) for the electric vehicle 10. FIG. The need condition N1 is another use area A1 (here, another site H1) different from the current use area A1 of the electric vehicle 10, or another person different from the owner of the electric vehicle 10 (for example, another This is the condition of the vehicle information D2 (for example, the degree of deterioration R1 of the battery 5, the model year, the mileage, etc.) required by the merchant or the individual. If the electric vehicle 10 having the vehicle information D2 that meets the needs condition N1 exists, the matching notification unit 73 (see FIG. 2) notifies.

In this embodiment, the need condition acquisition unit 71 in FIG. 2 acquires the need condition N1 for the electric vehicle 10 in step S201 in FIG. For example, the input means 22 of the base terminal 20 is operated to input the need condition N1. Here, the need condition N1 input by operating the input means 22 is transmitted to the management server 30 (see FIG. 2) via the first communication section 51. FIG. The need condition acquisition unit 71 acquires the need condition N1 transmitted to the management server 30 . In this way, the needs condition acquisition unit 71 determines whether the electric vehicle 10 meets the base H1 used in the other use area A1 or the needs condition N1 required by others. A rental car company using the electric vehicle management system 100 can hand over the electric vehicle 10 according to the base H1 used in the other use area A1 or the needs N1 of others. The need condition N1 acquired by the need condition acquisition unit 71 is stored in the storage unit 50. FIG.

Next, in step S202 of FIG. 6, the selection unit 72 of FIG. Select area A1. Here, the value of each information of the vehicle information D2 (for example, the degree of deterioration R1 of the battery 5, the travel distance, etc.) is changed according to the use area A1 in which the electric vehicle 10 will be used in the future. Depending on which area A1 the electric vehicle 10 will be used in from now on, it is possible to predict how the numerical value of each information of the vehicle information D2 will be changed after the elapse of a predetermined period of time. For example, assuming that the electric vehicle 10 will be used in the second use area A12 where the battery 5 is likely to deteriorate, after a predetermined period of time has passed, the deterioration of the battery 5 will accelerate and the degree of deterioration R1 will become higher. , the mileage is also expected to be relatively long. On the other hand, assuming that the electric vehicle 10 will be used in the third use area A13 where the deterioration of the battery 5 is less likely to occur in the future, the deterioration of the battery 5 will not be accelerated after a predetermined period of time, and the degree of deterioration R1 will be high. It is predicted that it will be difficult to increase the distance traveled. In this manner, by changing the use area A1 based on the selection of the use area A1 by the selection unit 72, the electric vehicle 10 can be made to meet the needs condition N1. Therefore, it is easy to make the electric vehicle 10 that meets the need condition N1, and the rental car company using the electric vehicle management system 100 has the base H1 used in the other use area A1 or the vehicle information D2 required by others. It is easy to hand over the electric vehicle 10 to a base H1 to be used in another use area A1 or to another person.

The selection unit 72 predicts the numerical value of each information (for example, the deterioration degree R1 of the battery 5, the travel distance, etc.) of the vehicle information D2 after a predetermined period of time has passed when the electric vehicle 10 is used in each usage area A1. . Then, the selection unit 72 selects the use area A1 having the numerical value of the vehicle information D2 that is closest to the needs condition N1 as the change destination of the use area A1 of the electric vehicle 10 . For example, assume that a need condition N1 is set for the first electric vehicle 11 . At this time, the selection unit 72 predicts numerical values of each information of the vehicle information D2 when the first electric vehicle 11 is used in the first use area A11 for a predetermined period. Similarly, the selection unit 72 predicts the numerical value of each information of the vehicle information D2 when the first electric vehicle 11 is used in the second use area A12 for a predetermined period, and , predicts the numerical value of each information of the vehicle information D2 when the vehicle is used in the third use area A13 for a predetermined period. Then, the use area A1 in which the numerical value of the predicted vehicle information D2 is closest to the need condition N1 is selected as the use area A1 to be used by the first electric vehicle 11 from now on. Information about the use area A1 selected by the selection unit 72 is notified by the notification unit 67 in FIG. 2, for example. When notified by the notification unit 67, the corresponding electric vehicle 10 is moved, and the information regarding the use area A1 linked to the electric vehicle 10 in the use area information D1 is updated.

Next, in step S203 of FIG. 6, the conformity notification unit 73 of FIG. notify you of what you have done. Here, the numerical value of each information of the needs condition N1 and the vehicle information D2 of the electric vehicle 10 for which the needs condition N1 is set is compared. Then, when the numerical value of each information of the vehicle information D2 of the electric vehicle 10 is included within a predetermined range of the numerical value of each information of the vehicle information D2 set by the needs condition N1, it is determined that the needs condition N1 is met. to decide. At this time, the conformity notification unit 73 notifies that the needs condition N1 is conformed. Here, the compatibility notification unit 73 transmits a compatibility notification message to, for example, the base terminal 20 and displays the compatibility notification message on the screen 21 of the base terminal 20 . The conformity notification unit 73 may transmit a conformity notification mail to the base terminal 20 . After that, the corresponding electric vehicle 10 is handed over to another person who has set the need condition N1, or is moved to the storage location P1 at the base H1 where the need condition N1 is set. In this way, for example, a rental car company using the electric vehicle management system 100 can easily know that the electric vehicle 10 meets the needs condition N1 by receiving the notification that the needs condition N1 is met. Therefore, the rental car company using the electric vehicle management system 100 can hand over the electric vehicle 10 at a timing that meets the needs condition N1.

In this embodiment, the electric vehicle management system 100 is used by a rental car company. However, the electric vehicle management system 100 is not particularly limited as long as it is a business that owns a plurality of electric vehicles 10 and uses the electric vehicles 10 in a plurality of use areas A1, and may be an individual. Companies that use the electric vehicle management system 100 include companies that operate car sharing and companies that use the electric vehicle 10 as company vehicles (for example, companies).
