[0041] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Figure 1 1 is a block diagram showing an electric vehicle and a charging system according to an embodiment of the present invention. The charging system 100 according to the embodiment of the present invention includes a plurality of charging devices 110, a server-side information processing device 120 for managing the plurality of charging devices 110, and a client-side information processing device 220 mounted in the electric vehicle 1. The plurality of charging devices 110 are arranged in various locations.

[0043] The information processing devices 120 and 220 are configured to communicate with the communication network N1 through the communication units (communication modules) 121 and 221. The information processing device 120 is a computer that operates according to the control program stored in the storage unit 120a. The information processing device 220 is a computer that operates according to the control program stored in the storage unit 220a.

[0044] The client information processing device 220 is connected to an information output unit (eg, a display) 222 that outputs information to a user or the system of the electric vehicle 1 and an input unit (eg, a touch panel) 223 that inputs a request from the user.

[0045] The electric vehicle 1 includes a battery 3 for storing electric power for traveling, a charger 4 for charging the battery 3 with electric power from the outside, the above-mentioned information processing device 220 for processing information related to the use of the charging device 110, and a meter 6 for measuring the outside temperature and the amount of solar radiation. The information output unit 222 and the input unit 223 of the information processing device 220 can be used by the passengers of the electric vehicle 1.

[0046] The charging device 110 is provided with a charging cable 111 for transmitting power to the electric vehicle 1 and a payment system 112 capable of receiving and paying charges. It should be noted that the method of transmitting power from the charging device 110 to the electric vehicle 1 is not limited to the method through the charging cable 111, and a non-contact power transmission method using electromagnetic action for transmitting power may also be used.

[0047] The electric vehicle 1 moves to a location where the charging device 110 is installed, and receives power from the charging device 110 through the charger 4, so that the battery 3 can be charged. On the other hand, sometimes the charging device 110 is in a non-chargeable state, such as when the charging device 110 is in high temperature or exposed to the sun, for example, the payment system 112 of the charging device 110 stops due to overheating, so that charging cannot be started.

[0048] <Movement of Electric Vehicle>

[0049] Figure 2 2 is a flowchart showing the control process performed by the information processing device of the electric vehicle. The information processing device 220 performs the control process during the system operation of the electric vehicle 1. In the control process, the information processing device 220 repeatedly performs a loop process (steps S1, S5, S9) for determining the occurrence of a corresponding event. In the loop process, first, the information processing device 220 determines whether there is a request for information output from the charging device 110 of the user (step S1). For example, the user can issue a request for information output from the input unit 223 of the information processing device 220.

[0050] If the result of the determination in step S1 is that there is a request for information output, the information processing device 220 requests information from the information processing device 120 on the server side through communication (step S2), and receives information on whether multiple charging devices 110 in various places can be charged from the information processing device 120 (step S3). The information on whether charging can be performed includes the identification information of each charging device 110 and the information on whether the charging device 110 can be charged in an associated state.

[0051] As will be described in detail later, among the multiple charging devices 110, there may be a charging device 110 that may not be able to be charged but gives preferential treatment to the user when charging is attempted. In this case, the information on whether or not charging is transmitted from the information processing device 120 to the charging device 110 includes information indicating the charging device 110 that is giving the preferential treatment. That is, in the above case, the information on whether or not charging is possible includes the identification information of the charging device 110 that is giving the preferential treatment and the information indicating that the preferential treatment is being given in an associated state.

[0052] Then, the information processing device 220 outputs the information on whether the charging devices 110 in various places can be charged through the information output unit 222 (step S4). The method of outputting the information is not particularly limited. For example, a method of superimposing the marks of multiple charging devices 110 on the map display and superimposing a display indicating that the charging device 110 cannot be charged can be adopted. Alternatively, as a method of outputting the information on whether the charging can be performed, a method of displaying various information such as the names, locations and fees of multiple charging devices 110 in a list and displaying the information that the charging device 110 cannot be charged in a list box can be adopted. Alternatively, in the above-mentioned list display, a method of excluding the display of the charging device that cannot be charged from the list can be adopted. In addition, when there is a charging device 110 that is being given preferential treatment among the multiple charging devices 110, information indicating that the preferential treatment is being given is output or attached in association with the charging device 110.

[0053] It should be noted that the device that communicates with the information processing device 120 on the server side to execute the processing of steps S1 to S4 is not limited to the information processing device 220 installed in the electric vehicle 1, but may also be a mobile terminal held by the user. After step S4, the information processing device 220 returns the processing to the loop processing of determining the occurrence of the event again.

[0054] In this loop processing, the information processing device 220 further attempts to charge the charging device 110 to determine whether charging is not possible (step S5). When the judgment result of step S5 is "yes", the information processing device 220 obtains the information of the external temperature and solar radiation measured by the meter 6 of the electric vehicle 1 (step S6). In addition, the information processing device 220 obtains the identification information of the charging device 110 from the charger 4 (step S7). Then, the information processing device 220 sends the identification information of the non-chargeable charging device 110, the information of the external temperature and the amount of solar radiation, that is, the environmental information when charging is not possible, and the information indicating that charging is not possible to the information processing device 120 on the server side through the communication unit 221 (step S8). After that, the information processing device 220 returns the processing to the loop processing of determining the occurrence of the event again.

[0055] In this loop processing, the information processing device 220 further attempts to charge the charging device 110 to determine whether the charging is proceeding normally (step S9). When the judgment result of step S9 is "yes", the information processing device 220 obtains the information of the external temperature and solar radiation measured by the meter 6 of the electric vehicle 1 (step S10). In addition, the information processing device 220 obtains the identification information of the charging device 110 from the charger 4 (step S11). Then, the information processing device 220 sends the identification information of the charging device 110 that starts charging normally, the information of the external temperature and the amount of solar radiation, that is, the environmental information during normal charging, and the information indicating normal charging to the information processing device 120 on the server side through the communication unit 221 (step S12). After that, the information processing device 220 returns the processing to the loop processing of determining the occurrence of the event again. It should be noted that the processing of steps S9 to S12 can be omitted.

[0056] The control processing program is stored in a non-transitory computer readable medium such as the storage unit 220a of the information processing device 220. The information processing device 220 may be configured to read the program stored in the portable non-transitory storage medium and execute the program. The portable non-transitory storage medium may store the control processing program.

[0057] <Server-side actions>

[0058] Figure 3A and Figure 3B It is a flowchart representing the control processing performed by the information processing device on the server side. The information processing device 120 on the server side repeatedly executes a loop processing for determining the occurrence of the corresponding event (steps S21, S24, S30, S34). In the loop processing, first, the information processing device 120 determines whether the information indicating that charging is not possible is received from the electric vehicle 1 (step S21). If the result is that the information is sent, the information processing device 120 obtains the information (step S22), and updates the data map that collects the information on whether each charging device 110 can be charged based on the identification information of the charging device 110 contained in the information (step S23). After that, the information processing device 120 returns the processing to the loop processing for determining the occurrence of the event.

[0059] In this loop processing, the information processing device 120 determines whether the information of normal charging is received from the electric vehicle 1 (step S24). If the result is that the information is received, the information processing device 120 obtains the information (step S25) and updates the data map that collects the information on whether the charging device 110 can be charged contained in the information (step S26). After that, the information processing device 120 returns the processing to the loop processing of determining the occurrence of the event.

[0060] Figure 4 1 is a diagram illustrating a data map that collects information about whether each charging device can charge. The information processing device 120 generates a data map for each individual charging device 110. Figure 4 As shown, the data graph is a graph of environmental information that collects data of the outside temperature and solar radiation during normal charging and when charging is not possible. The environmental information is data obtained when a plurality of electric vehicles 1 attempt to charge at the charging facility 110 .

[0061] It should be noted that, although the above data graph includes information during normal charging, the data graph may not include information during normal charging. The following is an example of including information during normal charging in the data graph. Figure 4 As shown, when the information of the data graph is graphed, a mark (plot) for normal charging and a mark for non-charging are displayed on a coordinate whose two axes represent the external temperature and the solar radiation amount, respectively.

[0062] In the loop process of determining the occurrence of the event, the information processing device 120 determines whether the data map is updated with the information that charging is not allowed (step S27). If the result is "yes", the information processing device 120 updates the area of ​​the outside temperature and solar radiation that is estimated to be not charging (hereinafter referred to as "not charging area") in the data map (step S28).

[0063] Figure 5A to Figure 5DThis is a graph showing an example of a non-chargeable area set based on non-chargeable environmental information in the first embodiment. Figure 6A to Figure 6D : is a graph showing an example of a non-chargeable area set according to non-chargeable environment information in Embodiment 2. Embodiment 1 is an example of setting a non-chargeable area E by performing extrapolation, and Embodiment 2 is an example of setting a non-chargeable area Ea by performing interpolation.

[0064] like Figure 5A As shown, when the non-chargeable environmental information in the data graph is a point (i.e., mark Q1), the information processing device 120 sets the area where the external temperature is higher than the external temperature of the environmental information and the solar radiation is greater than the solar radiation of the above environmental information as the non-chargeable area E.

[0065] It should be noted that the environmental information measured when charging is not possible is usually not the boundary value that distinguishes normal charging and non-charging, but mostly the external temperature slightly higher than the boundary and the solar radiation slightly larger than the boundary. That is, usually, there is a difference between the boundary that distinguishes whether charging can be performed and the environmental information measured when charging is not possible. Therefore, considering this difference, the area above the point where the external temperature is slightly lower and the solar radiation is slightly lower than the environmental information measured when charging is not possible can be set as the non-charging area E. An example that does not consider the above difference is given below.

[0066] like Figure 5B to Figure 5D As shown, when there are multiple non-chargeable environmental information points (i.e., marks Q1 to Q4) in the data graph, the information processing device 120 performs extrapolation on the multiple marks Q1 to Q4. Through extrapolation, multiple environmental information that has not been observed but is predicted to be non-chargeable can be obtained. The multiple environmental information is equivalent to each point on the straight line R2 to R4 connecting the above-mentioned multiple marks Q1 to Q4. After calculating the straight line R2 to R4 by extrapolation, the information processing device 120 sets the area where the external temperature is higher and the solar radiation is greater than each point on the straight line R2 to R4 as the non-chargeable area E.

[0067] The above example shows an example of performing extrapolation when there is non-chargeable environmental information at multiple points, but Figure 6B to Figure 6D As shown, the interpolation value can be replaced by the interpolation value. In the case of the interpolation value, the non-chargeable area Ea obtained by removing a part of the area from the non-chargeable area E in the case of the extrapolation value is set. Half of the above-mentioned removed part of the area is the most biased towards the environment information with low outside temperature and large solar radiation among several non-chargeable environmental information (for example Fig.6D The other half of the above-mentioned partial area is the environment information with high external temperature and small solar radiation (e.g. Fig.6DCompared with the mark Q3 in the figure, the radiation amount is smaller.

[0068] Even when extrapolation or interpolation is performed, there are often differences between the boundary that distinguishes normal charging and non-charging and the large amount of environmental information obtained by interpolation. Therefore, even when extrapolation or interpolation is performed, considering the above differences, the area above the point where the outside temperature is slightly lower and the solar radiation is slightly lower than the straight line R2 to R4 obtained by interpolation can be set as the non-charging area E, Ea.

[0069] After updating the non-chargeable areas E and Ea, the information processing device 120 then updates the areas P and Pa that may not be chargeable but give preferential treatment to the user when attempting to charge (hereinafter referred to as "preferential treatment areas") (step S29). Figure 5A to Figure 5D , Figure 6A to Figure 6D In the figure, preferential areas P and Pa are represented by areas sandwiched by dotted lines. The above-mentioned non-chargeable areas E and Ea are areas that are presumed to be non-chargeable when both the external temperature and the amount of solar radiation are included in the area. However, even in the non-chargeable areas E and Ea, there is a possibility that charging is actually possible. However, when charging is not attempted in the non-chargeable areas E and Ea, it is actually impossible to find a chargeable area. Therefore, it is hoped that the data of the data map will be further enriched so that it can be inferred with higher accuracy whether charging is possible. In order to infer whether charging is possible with higher accuracy, it is necessary to enrich the data around the boundaries for distinguishing whether charging is possible. In response to such wishes, the information processing device 120 sets preferential areas P and Pa to allow users to try charging instead of giving preferential treatment to users. The above-mentioned preferential treatment is not particularly limited and can take various forms such as reducing charging costs and granting beneficial points.

[0070] like Figure 5A to Figure 5D , Figure 6A to Figure 6D As shown, the information processing device 120 sets the area of ​​the specified range as the preferential area P, Pa according to the boundary of whether the non-chargeable area E, Ea can be charged (the boundary of constant external temperature and the boundary of constant solar radiation may be excluded). The above-mentioned specified range can be a range of a preset external temperature range and a preset solar radiation range that can maintain the possibility of charging to a certain extent even if it is determined to be non-chargeable. In step S29, the information processing device 120 updates the preferential area P, Pa according to the non-chargeable area E, Ea updated in step S28. After that, the information processing device 120 returns the processing to the loop processing of the occurrence of the judgment event.

[0071] In this loop processing, the information processing device 120 then determines whether the specified estimated time has arrived (step S30). The estimated time can be set to, for example, a cycle for updating weather information. As a result, if it is determined to be "yes" in step S30, the information of the external temperature and solar radiation amount of each location where multiple charging devices 110 are located is extracted from the weather information of each place as the environmental information at the time of estimation (step S31). Then, the information processing device 120 applies the environmental information at the time of estimation to the data map of each charging device 110 to estimate whether each charging device 110 can be charged (step S32). That is, if the external temperature and solar radiation amount as the environmental information at the time of estimation are included in the non-charging area E, the information processing device 120 estimates that it is not chargeable. In addition, the information processing device 120 applies the environmental information at the time of estimation to the data map of each charging device 110 to determine whether the environmental information of each charging device 110 is included in the preferential treatment area P, Pa (step S33). That is, the charging device 110 that is given preferential treatment when attempting to charge is extracted. Thereafter, the information processing device 120 returns the processing to the loop processing of determining the occurrence of an event.

[0072] In this loop processing, the information processing device 120 next determines whether there is a request to send information to the charging device 110 from the client information processing device 220 (step S34). Then, if it is determined to be "yes" in step S34, the information of multiple charging devices 110 including the estimated result of whether charging is possible in step S32 and the information about the charging device 110 given preferential treatment in step S33 are sent to the client information processing device 220 (step S34). After that, the information processing device 120 returns the processing to the loop processing of determining the occurrence of the event.

[0073] The client information processing device 120 uses the above Figure 2 The control process of step S24 receives the information of the charging device 110 sent in step S24, and outputs the information to the user (for example, the passenger of the electric vehicle 1). Therefore, it is possible to reduce the user's reckless movement of the electric vehicle 1 to the charging device 110 that is likely to be unchargeable for charging. In addition, if there is a charging device 110 that is given preferential treatment by attempting to charge although it is likely to be unchargeable, the user can identify the charging device 110.

[0074] The control processing program is stored in a non-transitory storage medium such as the storage unit 120a of the information processing device 120. The information processing device 120 may be configured to read the program stored in the portable non-transitory storage medium and execute the program. The portable non-transitory storage medium may store the control processing program.

[0075] As described above, according to the charging system 100 of the present embodiment, a plurality of charging devices 110 are included. In addition, the charging system 100 includes an information processing device 120. When a charging device 110 that cannot be charged appears among the plurality of charging devices 110 when the electric vehicle 1 attempts to charge, the information processing device 120 collects environmental information when the charging device 110 cannot be charged, and the environmental information when the charging cannot be charged is information about the external temperature and the amount of solar radiation. In addition, the charging system 100 includes an information output unit 222 that can be used by the user. Then, the information processing device 120 estimates whether the charging device 110 set at each location can be charged at each time point based on the collected environmental information when the charging cannot be charged, and the environmental information when the external temperature and the amount of solar radiation at each time point and each location are estimated. Therefore, the information processing device 120 can make an estimate of whether the charging can be charged that is suitable for reality based on the information collected during the normal use of the plurality of charging devices 110. In addition, the information output unit 222 outputs the information on whether the charging can be charged estimated by the information processing device 120. Therefore, based on the result of the estimation, the user can reduce the number of times in which the electric vehicle 1 to be charged is directed to the charging facility 110 where charging is not allowed.

[0076] The locations where the multiple charging devices 110 are installed have different characteristics, such as good ventilation or direct sunlight, etc. In this case, even at the same external temperature and the same amount of solar radiation, the boundary value of whether charging can be performed sometimes varies for each charging device 110, for example, one charging device 110 cannot be charged, while another charging device 110 can be charged normally, etc.

[0077] Therefore, according to the charging system 100 of the present embodiment, the information processing device 120 generates a data map that collects the environmental information when each charging device 110 is not chargeable, and uses the data map of each charging device 110 to infer whether each charging device 110 can be charged. In other words, when one of the multiple charging devices 110 is referred to as the first charging device 110, the information processing device 120 collects the information of the external air temperature and the amount of solar radiation when the first charging device 110 is not chargeable (i.e., the environmental information when it is not chargeable) in association with the identification information of the first charging device 110. Then, the information processing device 120 generates a data map that collects the environmental information when it is not chargeable associated with the first charging device 110, and makes it correspond to the first charging device 110, and infers whether the first charging device 110 can be charged based on the data map. According to this configuration, the information processing device 120 can infer whether each of the multiple charging devices 110 can be charged based on the characteristics of the installation location of each charging device 110. Therefore, the user can obtain a high-precision inference result of whether each of the multiple charging devices 110 can be charged.

[0078] It should be noted that, if it is known that some charging devices 110 are set in the same environment, the information processing device 120 can collect the environmental information of these charging devices 110 when they cannot be charged and generate a data map. Then, the information processing device 120 can infer whether these charging devices 110 can be charged based on the data map.

[0079] Furthermore, according to the charging system 100 of the present embodiment, when there are a plurality of environmental information when charging is not possible, the information processing device 120 infers that charging is not possible based on the interpolated environmental information (interpolated environmental information). That is, the information processing device 120 includes the range where the outside temperature is higher than and the solar radiation is greater than the interpolated environmental information in the range of environmental information inferred as not being able to charge. According to such processing, even when the amount of collected environmental information when charging is not possible is small, whether charging is possible can be inferred within the range of various environmental information.

[0080] When the outside temperature is high and the solar radiation is large, so that the charging device 110 cannot be charged, other components of the charging device 110 (such as various measuring instruments, communication equipment, etc.) may also be abnormal. Therefore, according to the charging system 100 of this embodiment, the meter 6 of the electric vehicle 1 measures the environmental information (outside temperature and solar radiation) when charging is not possible, and the environmental information measured by the meter 6 is sent from the electric vehicle 1 to the information processing device 120. According to such a configuration, the information processing device 120 can reduce the occurrence of the situation where the environmental information when charging is not possible cannot be obtained due to abnormalities.

[0081] In addition, according to the charging system 100 of the present embodiment, when the environmental information at the time of estimation is within the prescribed range from the boundary that distinguishes whether charging is possible in the charging device 110 that is estimated to be non-chargeable, the information output unit 222 outputs information that gives preferential treatment to the user who attempts to charge. Specifically, when the environmental information at the time of estimation is in the preferential area P, Pa, the information processing device 120 sends the above-mentioned preferential treatment information, and the information output unit 222 outputs the information. With such a configuration, the user can be encouraged to try to charge the charging device 110 where the external temperature and solar radiation are around the boundary that distinguishes whether charging is possible. Therefore, the information processing device 120 can obtain a large amount of information about whether charging is possible around the above-mentioned boundary and the environmental information when charging is attempted, so that the accuracy of the estimation of whether charging is possible can be improved.

[0082] As described above, the electric vehicle 1 of the present embodiment includes a communication unit 221 and an information output unit 222 capable of communicating with the information processing device 120. Then, when charging is attempted at the charging device 110 but cannot be charged, the communication unit 221 sends information that charging is not possible to the information processing device 120. In addition, the communication unit 221 receives information from the information processing device 120 on whether the charging device 110 can be charged based on the outside temperature and the amount of solar radiation, and the information output unit 222 outputs the information. With such a configuration of the electric vehicle 1, it is possible to realize a process in which the information processing device 120 estimates whether a plurality of charging devices 110 can be charged, and a process in which the user riding the electric vehicle 1 is notified of the estimated result.

[0083] Furthermore, according to the electric vehicle 1 of the present embodiment, when charging is attempted but cannot be performed at the charging device 110, the communication unit 221 transmits information on the outside temperature and the amount of solar radiation, i.e., environmental information when charging is not possible, to the information processing device 120 in addition to information on the uncharging. With such a configuration of the electric vehicle 1, the information processing device 120 can avoid malfunctions even in a harsh environment while collecting environmental information when charging is not possible.

[0084] The charging system 100 and the electric vehicle 1 of the present embodiment are described above. However, the charging system and the electric vehicle of the present invention are not limited to the configuration of the above embodiment. For example, the above embodiment shows that the information processing device 120 on the server side collects environmental information when charging is not possible, and infers whether the charging device can be charged based on the environmental information when charging is not possible and the environmental information when inferred. However, the collection of the above environmental information and the processing of inferring whether charging can be performed can also be performed by the information processing device 220 mounted in the electric vehicle 1. In this case, the information processing device 220 can collect environmental information when charging is not possible by communicating with other electric vehicles 1 and receiving environmental information when other electric vehicles 1 are not charging. In addition, as in the case of the above embodiment, the information processing device 220 can generate a data map for each charging device 110, and infer whether the charging device 110 associated with the data map can be charged based on the data map. Through such a configuration, the same effect as the above embodiment can also be obtained.

[0085] In addition, in the case where there is a charging device 110 that is given preferential treatment if charging is attempted even though it may not be chargeable, the electric vehicle 1 can receive information about the charging device 110 that is given preferential treatment from the outside, and the information output unit 222 can output the information. The electric vehicle 1 may not have a function of receiving information about whether multiple charging devices 110 can be charged or outputting the information. According to such an electric vehicle 1, the user can be encouraged to try to charge the charging device 110 around the boundary where the outside temperature and the amount of solar radiation are at the boundary that distinguishes whether charging can be performed. Therefore, the information processing device 120 can obtain a large amount of information about whether charging can be performed and environmental information around the above-mentioned boundary, thereby improving the accuracy of the estimation of whether charging can be performed.

[0086] In addition, the details shown in the above-mentioned embodiment can be appropriately changed within the scope not departing from the gist of the invention.
