Summary of the Invention

Problems to be Solved by the Invention

[0004] Although not specified in the above Patent Document 1, the battery pack mounted on the vehicle by battery replacement may not be limited to a specific type of battery pack. For this reason, a battery pack that is not suitable for the vehicle may be mounted on the vehicle. In this case, there is a risk that the vehicle performance will deteriorate.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a control device and a control method capable of suppressing a decrease in vehicle performance caused by a battery pack mounted by battery replacement.

Means for Solving the Problems

[0006] The control device according to the first aspect of the present disclosure is a control device that controls an electric vehicle equipped with a replaceable battery, and includes a communication unit capable of receiving information stored in a storage device and a processor. The storage device stores battery characteristic information indicating the characteristics of the battery during driving of the electric vehicle in association with battery unique information unique to the battery. When the battery is replaced, the processor acquires, from the storage device through the communication unit, the battery characteristic information corresponding to the battery unique information of the battery after replacement, and uses the battery characteristic information acquired from the storage device to change the vehicle control in the electric vehicle.

[0007] In the control device according to the first aspect of the present disclosure, as described above, when the battery is replaced, the processor acquires the battery characteristic information corresponding to the battery unique information of the battery after replacement, and uses the acquired battery characteristic information to change the vehicle control in the electric vehicle. Thereby, it is possible to perform vehicle control suitable for the battery characteristics of the battery after replacement using the battery characteristic information corresponding to the battery after replacement. As a result, it is possible to suppress a decrease in the performance of the vehicle due to the battery pack mounted by battery replacement.

[0008] In the control device according to the above first aspect, preferably, when the processor changes the vehicle control using the battery characteristic information corresponding to the battery after replacement, the processor notifies the user of the electric vehicle of information regarding the change in the vehicle control. With this configuration, the user can recognize that the vehicle control has been changed due to the battery replacement.

[0009] In this case, preferably, the processor notifies the user of the information regarding the change by transmitting the information regarding the change to at least one of a display device mounted on the electric vehicle and a user terminal owned by the user. With this configuration, since the user can visually recognize the information regarding the change, it is possible to easily convey to the user that the vehicle control has been changed.

[0010] In the control device according to the first aspect, preferably, when the battery characteristic information corresponding to the replaced battery is stored in the storage device, the processor determines whether it is necessary to change the vehicle control based on the battery characteristic information corresponding to the replaced battery stored in the storage device. When it is determined that it is necessary to change the vehicle control, the vehicle control is changed, and when it is determined that there is no need to change the vehicle control, the current vehicle control is maintained. Further, when the battery characteristic information corresponding to the replaced battery is not stored in the storage device, the processor maintains the current vehicle control. With this configuration, the vehicle control can be changed only when it is determined that it is necessary to change the vehicle control based on the battery characteristic information stored in the storage device.

[0011] The control method according to the second aspect of the present disclosure is a control method for controlling an electric vehicle equipped with a replaceable battery, including a step of acquiring battery characteristic information corresponding to the battery unique information of the replaced battery from a storage device that stores battery characteristic information indicating the characteristics of the battery during driving of the electric vehicle in association with the battery unique information unique to the battery, and a step of changing the vehicle control of the electric vehicle using the battery characteristic information corresponding to the replaced battery acquired in the acquiring step when the battery is replaced.

[0012] In the control method according to the second aspect of the present disclosure, as described above, when the battery is replaced, the vehicle control in the electric vehicle is changed using the battery characteristic information corresponding to the battery unique information of the replaced battery. Thereby, it is possible to provide a control method capable of suppressing a decrease in vehicle performance due to the battery pack mounted by battery replacement.

Effects of the Invention

[0013] According to the present disclosure, it is possible to suppress a decrease in vehicle performance due to the battery pack mounted by battery replacement.

Mode for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their descriptions are not repeated.

[0016] [First Embodiment] [Configuration of Battery Replacement System] FIG. 1 is a diagram showing a battery replacement system 900 including an electric vehicle 100, a server 200, and a battery replacement device 300 according to the first embodiment. Note that the server 200 is an example of the "storage device" of the present disclosure.

[0017] The electric vehicle 100 includes a vehicle ECU (Electronic Control Unit) 10, a DCM (Data Communication Module) 20, a battery pack 30, and a car navigation device 40. The battery pack 30 is replaceable in a battery replacement device 300. Note that the vehicle ECU 10 and the battery pack 30 are examples of the "control device" and the "battery" of the present disclosure, respectively.

[0018] Note that the user of the electric vehicle 100 owns a user terminal 150 (e.g., a smartphone).

[0019] The electric vehicle 100 is, for example, a PHEV (Plug-in Hybrid Electric Vehicle), a BEV (Battery Electric Vehicle), or an FCEV (Fuel Cell Electric Vehicle).

[0020] The battery pack 30 includes a battery ECU 31 and a plurality of battery cells 32. Each of the plurality of battery cells 32 stores electric power used for driving (such as traveling) the electric vehicle 100. The battery ECU 31 manages (controls) each of the plurality of battery cells 32. In addition, information unique to the battery pack 30 (such as information on the type of battery) is stored in the battery ECU 31.

[0021] The DCM 20 is configured to be communicable with a communication device outside the vehicle. The DCM 20 is communicable with a server 200 (a communication unit 230 described later). The DCM 20 may also be communicable with the user terminal 150.

[0022] The car navigation device 40 displays various information (such as map information and video content) on a display screen and notifies various information (such as traffic information and weather information, etc.) by voice.

[0023] The vehicle ECU 10 includes a processor 1, a memory 2, and a communication unit 3. In addition to the programs executed by the processor 1, the memory 2 stores information used in the programs (such as maps, mathematical formulas, and various parameters).

[0024] The communication unit 3 communicates with each of the DCM 20, the battery ECU 31, and the car navigation device 40, for example, by CAN (Controller Area Network) communication.

[0025] The server 200 includes a processor 210, a memory 220, and a communication unit 230. In addition to the programs executed by the processor 210, the memory 220 stores information used in the programs (such as maps, mathematical formulas, and various parameters).

[0026] The memory 220 stores the table 221 shown in FIG. 2. In the table 221, the battery type, the vehicle type, and the battery characteristics are stored in association with each other. The information on the battery type (hereinafter referred to as battery-specific information) includes the information on the battery manufacturer and the information on the battery model. The information on the vehicle type (hereinafter referred to as vehicle information) includes the information on the vehicle manufacturer and the information on the vehicle model. The battery characteristic information indicates the characteristics of the battery pack when the vehicle is driven (such as during driving and charging). Note that the information on the battery type is an example of the "battery-specific information" of the present disclosure.

[0027] The information in Table 221 is created based on the characteristics of the battery pack 30 during the driving (such as during driving and charging) of each of the plurality of electric vehicles including the electric vehicle 100. For example, assume that the electric vehicle 100 is a vehicle of type F of manufacturer E and is equipped with a battery pack 30 of type B of manufacturer A. In this case, the characteristics of the battery pack 30 (information such as output voltage, output power, and battery temperature) during the driving of the electric vehicle 100 are transmitted from the electric vehicle 100 to the server 200. Then, the information in Table 221 stored in the memory 220 of the server 200 (battery-specific information of type B of manufacturer A and battery characteristic information corresponding to the vehicle information of type F of manufacturer E) is updated based on the information from the electric vehicle 100. If the battery-specific information of type B of manufacturer A and the battery characteristic information corresponding to the vehicle information of type F of manufacturer E are not stored in the memory 220, the information from the electric vehicle 100 is newly registered in the memory 220.

[0028] The communication unit 230 is configured to be communicable with the DCM 20 of the electric vehicle 100. Note that the communication unit 230 may also be communicable with the user terminal 150.

[0029] Referring to FIG. 1 again, the battery swapping device 300 includes a battery swapping device main body 300a where battery swapping is performed and a storage 300b where the battery pack 30 is stored. Various types of battery packs 30 may be stored in the storage 300b. The battery swapping device main body 300a is a device that performs battery swapping to replace the battery pack 30 mounted on the electric vehicle 100 with the battery pack 30 stored in the storage. The storage 300b is provided adjacent to the battery swapping device main body 300a. An entrance / exit 302 for the electric vehicle 100 to enter and exit is provided in the battery swapping device 300 (battery swapping device main body 300a).

[0030] Here, in the conventional battery swapping system, the battery pack mounted on the vehicle by battery swapping may not be limited to a specific type of battery pack. For this reason, a battery pack that is not suitable for the vehicle may be mounted on the vehicle.

[0031] Therefore, in the first embodiment, when the battery pack 30 is replaced, the processor 1 acquires, through the communication unit 3, battery characteristic information corresponding to the battery unique information of the battery pack 30 after replacement from the server 200 (memory 220). Specifically, the processor 1 acquires, from the server 200, battery characteristic information corresponding to the battery unique information of the battery pack 30 after replacement and the vehicle information of the electric vehicle 100.

[0032] Then, the processor 1 uses the battery characteristic information acquired from the server 200 to change the vehicle control in the electric vehicle 100. For example, when the battery characteristic information includes information indicating that the rise in the battery temperature during driving of the electric vehicle 100 is large, the processor 1 may reduce the maximum value of the output power (voltage) of the battery below the normal value (for example, a reference value determined by specifications, etc.).

[0033] <Control method for changing vehicle control> Next, with reference to FIGS. 3 and 4, a control method for changing the vehicle control of the electric vehicle 100 will be described.

[0034] FIG. 3 shows a sequence when the information of the server 200 is updated based on the battery characteristic information during driving of the electric vehicle 100. First, it is assumed that the driving of the electric vehicle 100 starts at step S10.

[0035] At step S11, the vehicle ECU 10 transmits, through the DCM 20, data on the battery characteristics (data such as battery output, battery voltage, and battery temperature) of the battery pack 30 during driving of the electric vehicle 100 to the server 200. Specifically, the processor 1 of the vehicle ECU 10 acquires the above data from the battery ECU 31 through the communication unit 3 of the vehicle ECU 10. Then, the processor 1 transmits the above data to the DCM 20 through the communication unit 3 and transmits the above data to the server 200 through the DCM 20. At this time, the vehicle information of the electric vehicle 100 may also be transmitted to the server 200.

[0036] In step S12, the vehicle ECU 10 determines whether or not the running of the electric vehicle 100 has stopped. For example, the vehicle ECU 10 may determine whether or not the running of the electric vehicle 100 has stopped based on changes in the position information of the electric vehicle 100 by a GPS (not shown), changes in detection values of an acceleration sensor (speed sensor, etc.) (not shown), and the like. If the running of the electric vehicle 100 has stopped (Yes in S12), the processing of the electric vehicle 100 ends. If the running of the electric vehicle 100 has not stopped (No in S12), the processing returns to step S11.

[0037] In step S20, the server 200 accumulates (stores) the data of step S11 in association with the battery specific information of the battery pack 30 and the vehicle information of the electric vehicle 100. The above data may be accumulated in the memory 220.

[0038] In step S21, the server 200 determines whether or not the running of the electric vehicle 100 has stopped. For example, the server 200 may determine that the electric vehicle 100 has stopped based on a notification from the electric vehicle 100, or may determine based on changes in the position information of the electric vehicle 100 and the like. If it is determined that the running of the electric vehicle 100 has stopped, the processing proceeds to step S22. If it is determined that the running of the electric vehicle 100 has not stopped, the processing returns to step S20.

[0039] In step S22, the server 200 performs data analysis for each combination of the battery specific information and the vehicle information using the data of step S11.

[0040] In step S23, the server 200 updates the battery characteristic information associated with the battery specific information. Specifically, the server 200 updates the battery characteristic information corresponding to the combination of the battery specific information and the vehicle information for which data analysis was executed in step S22 based on the analysis result of step S22. If the battery characteristic information corresponding to the above combination is not stored in the server 200 at the time of step S23, the information based on the analysis result of step S22 is newly registered in the memory 220.

[0041] Figure 4 is a diagram showing a sequence for changing the vehicle control of the electric vehicle 100 based on the battery characteristic information stored in the server 200. In step S30, it is assumed that the battery pack 30 of the electric vehicle 100 has been replaced in the battery replacement device 300.

[0042] In step S31, the vehicle ECU 10 receives the battery unique information of the replaced battery pack 30 from the battery ECU 31 through the communication unit 3.

[0043] In step S32, the vehicle ECU 10 transmits the battery unique information of the replaced battery pack 30 acquired in step S31 to the server 200 through the DCM 20. Specifically, the processor 1 of the vehicle ECU 10 transmits the battery unique information to the DCM 20 through the communication unit 3 of the vehicle ECU 10, and transmits the battery unique information to the server 200 through the DCM 20. In step S32, the electric vehicle 100 may also transmit the vehicle information of the electric vehicle 100 to the server 200.

[0044] In step S40, the server 200 determines whether the battery characteristic information corresponding to the battery unique information and the vehicle information of the electric vehicle 100 in step S32 is stored in the memory 220. That is, the server 200 determines whether there is a record of acquiring the data of the battery characteristics corresponding to the above battery unique information and vehicle information in the electric vehicle 100. If the battery characteristic information is stored (Yes in S40), the process proceeds to step S41. If the battery characteristic information is not stored (No in S40), the process proceeds to step S42.

[0045] In step S41, the server 200 transmits the battery characteristic information corresponding to the replaced battery pack 30 and the vehicle information of the electric vehicle 100 to the electric vehicle 100. Then, the control of the server 200 ends.

[0046] In step S42, the server 200 transmits to the electric vehicle 100 information indicating that the battery characteristic information corresponding to the battery pack 30 after replacement and the vehicle information of the electric vehicle 100 is not stored in the memory 220 (information indicating the absence of data). Note that the information indicating the absence of the above data may be transmitted to the user terminal 150. Thereafter, the control of the server 200 ends.

[0047] In step S33, the vehicle ECU 10 determines whether it has received the battery characteristic information in step S41. That is, the vehicle ECU 10 determines whether there is a past record of the combination of the battery unique information of the battery pack 30 after replacement and the vehicle information of the electric vehicle 100. If the battery characteristic information has been received (Yes in S33), the process proceeds to step S34. If the battery characteristic information has not been received (when the notification in S42 is received) (No in S33), the process proceeds to step S36.

[0048] In step S34, the vehicle ECU 10 determines whether it is necessary to change the vehicle control based on the battery characteristic information received in step S33. For example, the vehicle ECU 10 may make the above determination by comparing the output power, output voltage, temperature characteristics, etc. in the battery pack 30 after replacement included in the battery characteristic information with the allowable values set in the electric vehicle 100. If it is necessary to change the vehicle control (Yes in S34), the process proceeds to step S35. If it is not necessary to change the vehicle control (No in S34), the process proceeds to step S36.

[0049] In step S35, the vehicle ECU 10 changes the vehicle control based on the determination result in step S34. Specifically, the vehicle ECU 10 changes the control parameters, threshold values, etc. in the vehicle control based on the above determination result. For example, the vehicle ECU 10 changes the output power, regenerative power, upper limit (lower limit) of the SOC (State Of Charge), charging time, sustainable distance, and electricity cost, etc. in the battery pack 30 after replacement. Next, the process proceeds to step S37.

[0050] In step S36, the vehicle ECU 10 maintains the current vehicle control. In other words, the vehicle ECU 10 does not change the vehicle control. Then, the control of the vehicle ECU 10 ends.

[0051] The vehicle ECU 10 notifies the user of the electric vehicle 100 of the information regarding the change in vehicle control in step S35.

[0052] Specifically, in step S37, the processor 1 of the vehicle ECU 10 transmits the information regarding the change in vehicle control to the car navigation device 40 through the communication unit 3.

[0053] Next, in step S38, the processor 1 of the vehicle ECU 10 causes the car navigation device 40 to display the information of step S37. Specifically, the processor 1 transmits a command signal for displaying the above information to the car navigation device 40 through the communication unit 3.

[0054] FIG. 5 shows an example of an image displayed on the car navigation device 40 in step S38. In the example shown in FIG. 5, the battery unique information, usage history, battery characteristics, and evaluation by the user of the replaced battery pack 30 are displayed on the car navigation device 40. Also, the content changed due to the change in vehicle control is displayed on the car navigation device 40. In the example shown in FIG. 5, the information on the output power of the battery pack 30 in the normal state (before change) (see the dashed line in FIG. 5) and the information on the output power of the battery pack 30 after the change in vehicle control (the hatched portion in FIG. 5) are displayed.

[0055] In the example shown in FIG. 5, the change in the output power of the battery pack 30 (change in vehicle control) is represented by the change in the length of the gauge to be displayed. Note that the change in vehicle control may be represented by the change in the display form of the icon.

[0056] As described above, in the first embodiment, when the battery pack 30 is replaced, the processor 1 acquires, from the server 200, battery characteristic information corresponding to the battery unique information of the battery pack 30 after replacement, and uses the acquired battery characteristic information to change the vehicle control in the electric vehicle 100. Thereby, since the electric vehicle 100 is controlled based on the battery characteristic information of the battery pack 30 after replacement, it is possible to suppress the execution of inappropriate vehicle control for the battery pack 30 after replacement. As a result, it is possible to suppress a decrease in the performance of the electric vehicle 100 due to the battery pack 30 mounted by battery replacement.

[0057] Also, in the first embodiment, the server 200 performs data analysis based on the battery characteristic information acquired from each of the plurality of electric vehicles 100. Thereby, since the amount of data used for the analysis can be easily increased, it is possible to acquire (calculate) more effective (highly reliable) battery characteristic information for suppressing a decrease in the performance of the electric vehicle 100.

[0058] [Second Embodiment] Next, with reference to FIGS. 6 to 9, the configuration according to the second embodiment will be described. The battery exchange system 910 according to the second embodiment does not include a server, unlike the first embodiment in which the battery exchange system 900 includes the server 200 and the electric vehicle 100. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and repeated description thereof will not be given.

[0059] <Configuration of Battery Exchange System> FIG. 6 is a diagram showing a battery exchange system 910 including an electric vehicle 100A and a battery exchange device 300 according to the second embodiment.

[0060] The electric vehicle 100A is different from the electric vehicle 100 of the first embodiment in that it includes a vehicle ECU 10A instead of the vehicle ECU 10. Note that the vehicle ECU 10A is an example of the "control device" of the present disclosure.

[0061] The vehicle ECU 10A includes a processor 1A, a memory 2A, and a communication unit 3A. In addition to the programs executed by the processor 1A, the memory 2A stores information used in the programs (for example, maps, mathematical formulas, and various parameters). Note that the memory 2A is an example of the "storage device" of the present disclosure.

[0062] The memory 2A stores the table 2B shown in FIG. 7. In the table 2B, the battery characteristic information is stored in association with the information on the battery type (battery-specific information). The information in the table 2B is updated based on the characteristics of the battery pack 30 when the electric vehicle 100A is driven (during running and charging, etc.).

[0063] <Control method for changing vehicle control> Next, with reference to FIGS. 8 and 9, a control method for changing the vehicle control of the electric vehicle 100A will be described. For steps where the same processing as in the first embodiment is performed, the same reference numerals will be given and repeated description will not be provided.

[0064] FIG. 8 shows a sequence when the information in the memory 2A is updated based on the battery characteristic information when the electric vehicle 100A is driven.

[0065] In step S11A, the vehicle ECU 10A accumulates the data on the battery characteristics of the battery pack 30 when the electric vehicle 100A is running, in association with the battery-specific information of the battery pack 30.

[0066] In step S12A, the vehicle ECU 10A determines whether or not the running of the electric vehicle 100A has stopped. If it is determined that the running of the electric vehicle 100A has stopped (Yes in S12A), the process proceeds to step S13. If it is determined that the running of the electric vehicle 100A has not stopped (No in S12A), the process returns to step S11A.

[0067] In step S13, the vehicle ECU 10A performs data analysis for each battery-specific information using the data accumulated in step S11A.

[0068] In step S14, the vehicle ECU 10A updates the battery characteristic information associated with the battery unique information. Specifically, the vehicle ECU 10A updates the battery characteristic information corresponding to the battery unique information for which data analysis was performed in step S13 based on the analysis result of step S13. If the battery characteristic information corresponding to the above battery unique information is not stored in the memory 2A at the time of step S14, information based on the analysis result of step S13 is newly registered in the memory 2A.

[0069] FIG. 9 is a diagram showing a sequence for changing the vehicle control of the electric vehicle 100A based on the battery characteristic information.

[0070] In step S33A, the vehicle ECU 10A determines whether the battery characteristic information corresponding to the battery unique information in step S31 is stored in the memory 2A. That is, the vehicle ECU 10A determines whether there is a record of acquiring the data of the battery characteristics corresponding to the above battery unique information in the electric vehicle 100A. If the battery characteristic information is stored (Yes in S33A), the process proceeds to step S34. If the battery characteristic information is not stored (No in S33A), the process proceeds to step S36.

[0071] Note that regarding other configurations and controls, since they are the same as those in the first embodiment described above, repeated description will not be given.

[0072] As described above, in the second embodiment, the processor 1A of the vehicle ECU 10A executes a process of changing the vehicle control using the information stored in the memory 2A of the vehicle ECU 10A. Thereby, the vehicle ECU 10A can change the vehicle control without performing communication (wireless communication) with an external device such as a server. As a result, it is possible to reduce the inoperability in the vehicle ECU 10A (electric vehicle 100A). Also, unlike the case where communication is performed between the external device and the vehicle ECU (electric vehicle), since the time required for communication (wireless communication) is not necessary, the vehicle control can be changed relatively quickly.

[0073] In the above-described first embodiment, an example is shown in which the vehicle ECU 10 acquires battery characteristic information stored in the server 200 and changes vehicle control (changes control parameters, etc.) using the acquired battery characteristic information. However, the present disclosure is not limited to this. For example, the server may calculate control parameters, etc. for changing vehicle control using the battery characteristic information stored in the server, and transmit the control parameters to the electric vehicle 100.

[0074] In the above-described first and second embodiments, an example is shown in which information regarding the change in vehicle control is displayed on the car navigation device 40. However, the present disclosure is not limited to this. For example, the information regarding the change in vehicle control may be displayed on the user terminal 150.

[0075] In the above-described first and second embodiments, an example is shown in which the change in vehicle control is not executed when the battery characteristic information corresponding to the replaced battery pack 30 is not stored in the server 200 (memory 2A). However, the present disclosure is not limited to this. Even in the above case, the vehicle control may be changed based on the information on the battery characteristics of the replaced battery pack 30.

[0076] In the above-described first and second embodiments, an example is shown in which data on battery characteristics during the running of the electric vehicle is accumulated. However, the present disclosure is not limited to this. For example, data on battery characteristics during charging and discharging of the electric vehicle may be accumulated.

[0077] In the above-described first and second embodiments, an example is shown in which information regarding the change in vehicle control is displayed on the car navigation device 40 or the like. However, the present disclosure is not limited to this. For example, the information regarding the change in vehicle control may be notified by voice from a speaker or the like.

[0078] In the above-described first and second embodiments, an example is shown in which the battery pack 30 is replaced. However, the present disclosure is not limited to this. Each of a plurality of battery cells may be replaced. In this case, the battery characteristic information for each battery cell may be managed in a server or the like.

[0079] In the above-described second embodiment, an example in which the table 2B is stored in the memory 2A of the vehicle ECU 10A has been shown, but the present disclosure is not limited to this. The table 2B may be stored in a storage device different from the memory 2A provided in the electric vehicle 100A.

[0080] In the above-described first and second embodiments, an example in which information regarding a change in vehicle control is notified to the user when the vehicle control is changed has been shown, but the present disclosure is not limited to this. Information indicating that the vehicle control is not changed may also be notified to the user.

[0081] In the above-described first and second embodiments, an example in which the battery-specific information includes information on the type of battery has been shown, but the present disclosure is not limited to this. For example, the battery-specific information may include information on the SOH (State Of health) of the battery in addition to the information on the type of battery. In this case, the battery characteristic information may be stored separately for each magnitude of the SOH (for example, every 10%) even if the types of the batteries are the same.

[0082] In the above-described first and second embodiments, an example in which the battery characteristics are stored for each type of battery pack has been shown, but the present disclosure is not limited to this. The battery characteristics may be stored for each battery pack (for example, for each battery pack ID). Also, in the first embodiment, the battery characteristics may be stored for each vehicle (for each vehicle ID) instead of being stored for each vehicle type.

[0083] The embodiments disclosed this time should be considered to be illustrative in all respects and not restrictive.
