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 relating to the first aspect of this disclosure is a control device for controlling an electric vehicle equipped with a replaceable battery, and comprises 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 when the electric vehicle is driven, associated with battery-specific information unique to the battery. When the battery is replaced, the processor obtains battery characteristic information corresponding to the battery-specific information of the replaced battery from the storage device via the communication unit, and uses the battery characteristic information obtained from the storage device to change the vehicle control in the electric vehicle.

[0007] In the control device relating to the first aspect of this disclosure, as described above, when a battery is replaced, the processor acquires battery characteristic information corresponding to the battery-specific information of the replaced battery, and modifies the vehicle control in the electric vehicle using the acquired battery characteristic information. This makes it possible to perform vehicle control suitable for the battery characteristics of the replaced battery using the battery characteristic information corresponding to the replaced battery. As a result, it is possible to suppress the deterioration of vehicle performance caused by the installed battery pack after battery replacement.

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

[0009] In this case, preferably, the processor notifies the user of the changes by transmitting information about the changes to at least one of a display device mounted on the electric vehicle and a user terminal owned by the user. With this configuration, the user can visually see the information about the changes, making it easy to communicate to the user that the vehicle control has been changed.

[0010] In the control device relating to the first aspect described above, preferably, the processor determines whether or not 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 battery characteristic information corresponding to the replaced battery is stored in the storage device. If it determines that it is necessary to change the vehicle control, the processor changes the vehicle control, and if it determines that it is not necessary to change the vehicle control, the current vehicle control is maintained. The processor also maintains the current vehicle control when battery characteristic information corresponding to the replaced battery is not stored in the storage device. 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 relating to the second aspect of this disclosure is a control method for controlling an electric vehicle equipped with a replaceable battery, comprising the steps of: acquiring battery characteristic information corresponding to the battery-specific information of a replaced battery from a storage device that stores battery characteristic information indicating the characteristics of the battery when the electric vehicle is driven, associated with battery-specific information unique to the battery; and, when the battery is replaced, changing the vehicle control of the electric vehicle using the battery characteristic information corresponding to the replaced battery acquired in the acquisition step.

[0012] In the control method relating to the second aspect of this disclosure, as described above, when a battery is replaced, the vehicle control in the electric vehicle is changed using battery characteristic information corresponding to the battery-specific information of the replaced battery. This makes it possible to provide a control method that can suppress the deterioration of vehicle performance caused by the installed battery pack after battery replacement. [Effects of the Invention]

[0013] According to this disclosure, it is possible to suppress the deterioration of vehicle performance caused by the installed battery pack when the battery is replaced. [Brief explanation of the drawing]

[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 description will not be 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. The server 200 is an example of the "storage device" of the present disclosure. [[ID=�2]]

[0017] [[ID=¿3]] 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 (for example, 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 (for example, 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. The memory 2 stores the program executed by the processor 1, as well as information used by the program (for example, maps, formulas, and various parameters).

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

[0025] The server 200 includes a processor 210, memory 220, and a communication unit 230. The memory 220 stores programs executed by the processor 210, as well as information used by the programs (for example, maps, formulas, and various parameters).

[0026] Memory 220 stores the table 221 shown in Figure 2. Table 221 stores battery type, vehicle type, and battery characteristics in relation to each other. Battery type information (hereinafter referred to as battery-specific information) includes battery manufacturer information and battery model information. Vehicle type information (hereinafter referred to as vehicle information) includes vehicle manufacturer information and vehicle model information. Battery characteristics information indicates the characteristics of the battery pack when the vehicle is running (during driving and charging, etc.). Note that battery type information is an example of "battery-specific information" in this disclosure.

[0027] The information in Table 221 is created based on the characteristics of the battery pack 30 during operation (driving, charging, etc.) for each of the multiple electric vehicles, including the electric vehicle 100. For example, suppose the electric vehicle 100 is a Type F vehicle from manufacturer E and is equipped with a Type B battery pack 30 from manufacturer A. In this case, the characteristics of the battery pack 30 during operation of the electric vehicle 100 (information such as output voltage, output power, and battery temperature) 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 characteristic information corresponding to the battery-specific information of Manufacturer A's Type B and the vehicle information of Manufacturer E's Type F) is updated based on the information from the electric vehicle 100. If the memory 220 does not contain battery characteristic information corresponding to the battery-specific information of Manufacturer A's Type B and the vehicle information of Manufacturer E's Type F, the information from the electric vehicle 100 is newly registered in the memory 220.

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

[0029] Referring again to Figure 1, the battery exchange device 300 comprises a battery exchange device body 300a where the battery exchange is performed, and a storage compartment 300b where the battery packs 30 are stored. Various types of battery packs 30 may be stored in the storage compartment 300b. The battery exchange device body 300a is a device that performs battery exchange, replacing the battery pack 30 installed in the electric vehicle 100 with a battery pack 30 stored in the storage compartment. The storage compartment 300b is attached to the battery exchange device body 300a. The battery exchange device 300 (battery exchange device body 300a) is provided with an entrance / exit 302 for the electric vehicle 100 to enter and exit.

[0030] In conventional battery replacement systems, the battery pack installed in the vehicle after replacement may not be limited to a specific type of battery pack. Therefore, a battery pack unsuitable for the vehicle may be installed.

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

[0032] The processor 1 then uses the battery characteristic information obtained from the server 200 to modify the vehicle control in the electric vehicle 100. For example, if the battery characteristic information includes information indicating a large rise in battery temperature when the electric vehicle 100 is running, the processor 1 may reduce the maximum output power (voltage) of the battery from the normal value (for example, a standard value defined by the specifications).

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

[0034] Figure 3 shows the sequence in which information on the server 200 is updated based on battery characteristic information when the electric vehicle 100 is in operation. First, let's assume that the electric vehicle 100 starts moving in step S10.

[0035] In step S11, the vehicle ECU 10 transmits data on the battery characteristics of the battery pack 30 (data such as battery output, battery voltage, and battery temperature) during the operation of the electric vehicle 100 to the server 200 via the DCM 20. Specifically, the processor 1 of the vehicle ECU 10 acquires the above data from the battery ECU 31 via the communication unit 3 of the vehicle ECU 10. The processor 1 then transmits the above data to the DCM 20 via the communication unit 3 and also transmits the above data to the server 200 via the DCM 20. At this time, 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 the electric vehicle 100 has stopped moving. For example, the vehicle ECU 10 may determine whether the electric vehicle 100 has stopped moving based on changes in the electric vehicle 100's position information from a GPS (not shown) or changes in detected values ​​from an acceleration sensor (speed sensor), etc. (not shown). If the electric vehicle 100 has stopped moving (Yes in S12), the processing of the electric vehicle 100 ends. If the electric vehicle 100 has not stopped moving (No in S12), the process returns to step S11.

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

[0038] In step S21, the server 200 determines whether the electric vehicle 100 has stopped moving. For example, the server 200 may determine that the electric vehicle 100 has stopped based on a notification from the electric vehicle 100, or based on a change in the electric vehicle 100's location information, etc. If it is determined that the electric vehicle 100 has stopped moving, the process proceeds to step S22. If it is determined that the electric vehicle 100 has not stopped moving, the process returns to step S20.

[0039] In step S22, the server 200 uses the data from step S11 to perform data analysis for each combination of battery-specific information and vehicle information.

[0040] In step S23, the server 200 updates the battery characteristic information linked to the battery-specific information. Specifically, the server 200 updates the battery characteristic information corresponding to the combination of battery-specific information and vehicle information analyzed in step S22, based on the analysis results 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 results of step S22 is newly registered in memory 220.

[0041] Figure 4 shows a sequence for changing the vehicle control of the electric vehicle 100 based on battery characteristic information stored in the server 200. Assume that in step S30, the battery pack 30 of the electric vehicle 100 is replaced by the battery replacement device 300.

[0042] In step S31, the vehicle ECU 10 receives battery-specific information for the replaced battery pack 30 from the battery ECU 31 via the communication unit 3.

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

[0044] In step S40, the server 200 determines whether the battery characteristic information corresponding to the battery-specific information and vehicle information of the electric vehicle 100 from step S32 is stored in the memory 220. That is, the server 200 determines whether the battery characteristic data corresponding to the battery-specific information and vehicle information has been acquired 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 battery characteristic information corresponding to the vehicle information of the replaced battery pack 30 and the electric vehicle 100 to the electric vehicle 100. After that, the control of the server 200 ends.

[0046] In step S42, the server 200 sends information to the electric vehicle 100 indicating that the battery characteristic information corresponding to the vehicle information of the replaced battery pack 30 and the electric vehicle 100 is not stored in the memory 220 (information indicating that there is no data). This information indicating that there is no data may also be sent to the user terminal 150. After that, the control of the server 200 ends.

[0047] In step S33, the vehicle ECU 10 determines whether or not it has received the battery characteristic information in step S41. That is, the vehicle ECU 10 determines whether or not there has been a past instance of a combination of the battery-specific information of the replaced battery pack 30 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 (if the notification in S42 has been received) (No in S33), the process proceeds to step S36.

[0048] In step S34, the vehicle ECU 10 determines whether or not 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, and temperature characteristics of the replaced battery pack 30, which are 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 modifies the vehicle control based on the determination result in step S34. Specifically, the vehicle ECU 10 modifies control parameters and thresholds in the vehicle control based on the above determination result. For example, the vehicle ECU 10 modifies the output power, regenerative power, upper (lower) limit of SOC (State of Charge), charging time, driving range, and energy consumption of the replaced battery pack 30. 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 make any changes to the vehicle control. After that, the control of the vehicle ECU 10 ends.

[0051] The vehicle ECU 10 informs the user of the electric vehicle 100 of the changes in vehicle control in step S35.

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

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

[0054] Figure 5 shows an example of an image displayed on the car navigation device 40 in step S38. In the example shown in Figure 5, the car navigation device 40 displays battery-specific information, usage history, battery characteristics, and user evaluation of the replaced battery pack 30. The car navigation device 40 also displays information that has been changed due to the vehicle control modification. In the example shown in Figure 5, information on the output power of the battery pack 30 under normal conditions (before modification) (see dashed line in Figure 5) and information on the output power of the battery pack 30 after the vehicle control modification (shaded area in Figure 5) are displayed.

[0055] In the example shown in Figure 5, the change in the output power of the battery pack 30 (change in vehicle control) is represented by a change in the length of the displayed gauge. Alternatively, the change in vehicle control may be represented by a change in the display pattern of the icon.

[0056] As described above, in the first embodiment, when the battery pack 30 is replaced, the processor 1 obtains battery characteristic information corresponding to the battery-specific information of the replaced battery pack 30 from the server 200, and uses the obtained battery characteristic information to change the vehicle control in the electric vehicle 100. As a result, the electric vehicle 100 is controlled based on the battery characteristic information of the replaced battery pack 30, so that inappropriate vehicle control for the replaced battery pack 30 is suppressed. Consequently, it is possible to suppress a decrease in the performance of the electric vehicle 100 due to the battery pack 30 installed after battery replacement.

[0057] Furthermore, in the first embodiment, the server 200 performs data analysis based on battery characteristic information acquired from each of the multiple electric vehicles 100. This makes it easy to increase the amount of data used for analysis, and thus more effective (reliable) battery characteristic information can be obtained (calculated) to suppress the deterioration of the performance of the electric vehicles 100.

[0058] [Second Embodiment] Next, the configuration of the second embodiment will be described with reference to Figures 6 to 9. Unlike the first embodiment, in which the battery replacement system 900 includes a server 200 and an electric vehicle 100, the battery replacement system 910 of the second embodiment does not include a server. Components identical to those of the first embodiment will be denoted by the same reference numerals, and repeated descriptions will not be provided.

[0059] <Configuration of the battery replacement system> Figure 6 shows a battery replacement system 910 comprising an electric vehicle 100A and a battery replacement device 300 according to the second embodiment.

[0060] The electric vehicle 100A differs from the electric vehicle 100 of the first embodiment in that it includes a vehicle ECU 10A instead of the vehicle ECU 10. The vehicle ECU 10A is an example of a "control device" as disclosed herein.

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

[0062] Memory 2A stores Table 2B, as shown in Figure 7. In Table 2B, battery characteristic information is stored in association with battery type information (battery-specific information). The information in Table 2B is updated based on the characteristics of the battery pack 30 when the electric vehicle 100A is in operation (during driving and charging, etc.).

[0063] <Control method related to changes in vehicle control> Next, with reference to Figures 8 and 9, a control method for changing the vehicle control of the electric vehicle 100A will be described. Steps in which the same process as in the first embodiment described above are denoted by the same reference numerals and will not be described repeatedly.

[0064] Figure 8 shows the sequence in which the information in memory 2A is updated based on the battery characteristics information when the electric vehicle 100A is in operation.

[0065] In step S11A, the vehicle ECU 10A stores data on the battery characteristics of the battery pack 30 during the operation of the electric vehicle 100A, associating it with the battery-specific information of the battery pack 30.

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

[0067] In step S13, the vehicle ECU 10A uses the data accumulated in step S11A to perform data analysis for each battery-specific piece of information.

[0068] In step S14, the vehicle ECU 10A updates the battery characteristic information linked to the battery-specific information. Specifically, the vehicle ECU 10A updates the battery characteristic information corresponding to the battery-specific information analyzed in step S13, based on the analysis results of step S13. If the battery characteristic information corresponding to the above battery-specific information is not stored in memory 2A at the time of step S14, the information based on the analysis results of step S13 is newly registered in memory 2A.

[0069] Figure 9 shows the sequence for changing the vehicle control of electric vehicle 100A based on battery characteristic information.

[0070] In step S33A, the vehicle ECU 10A determines whether battery characteristic information corresponding to the battery-specific information in step S31 is stored in memory 2A. That is, the vehicle ECU 10A determines whether battery characteristic data corresponding to the above battery-specific information has ever been acquired 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] The other configurations and controls are the same as those of the first embodiment described above, so no further explanation will be given.

[0072] As described above, in the second embodiment, the processor 1A of the vehicle ECU 10A executes a process to change the vehicle control using the information stored in the memory 2A of the vehicle ECU 10A. This allows the vehicle ECU 10A to change the vehicle control without communicating (wireless communication) with an external device such as a server. As a result, the processing load on the vehicle ECU 10A (electric vehicle 100A) can be reduced. Furthermore, unlike when communication takes place between an external device and the vehicle ECU (electric vehicle), the time required for communication (wireless communication) is not needed, so the vehicle control can be changed relatively quickly.

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

[0074] The first and second embodiments described above illustrate examples in which information regarding changes in vehicle control is displayed on the car navigation device 40, but the disclosure is not limited thereto. For example, information regarding changes in vehicle control may be displayed on the user terminal 150.

[0075] In the first and second embodiments described above, examples were shown in which vehicle control changes are not performed when battery characteristic information corresponding to the replaced battery pack 30 is not stored in the server 200 (memory 2A), but the disclosure is not limited thereto. Even in the above case, vehicle control may be changed based on the battery characteristic information of the replaced battery pack 30.

[0076] The first and second embodiments described above illustrate examples in which battery characteristic data is accumulated during the operation of an electric vehicle, but the disclosure is not limited thereto. For example, battery characteristic data may be accumulated during the charging and discharging of an electric vehicle.

[0077] In the first and second embodiments described above, examples were shown in which information regarding changes in vehicle control is displayed on a car navigation system 40 or the like, but the disclosure is not limited thereto. For example, information regarding changes in vehicle control may be announced by voice from a speaker or the like.

[0078] The first and second embodiments described above show examples in which the battery pack 30 is replaced, but the disclosure is not limited thereto. Each of the multiple battery cells may be replaced. In this case, battery characteristic information for each battery cell may be managed on a server or the like.

[0079] In the second embodiment described above, an example was shown in which table 2B is stored in the memory 2A of the vehicle ECU 10A, but the disclosure is not limited thereto. Table 2B may be stored in a different storage device provided in the electric vehicle 100A than memory 2A.

[0080] The first and second embodiments described above illustrate how information regarding changes to vehicle control is communicated to the user when vehicle control is modified, but the disclosure is not limited thereto. Information indicating that no changes to vehicle control are made may also be communicated to the user.

[0081] In the first and second embodiments described above, examples were shown in which battery-specific information included information about the type of battery, but the disclosure is not limited thereto. For example, in addition to information about the type of battery, the battery-specific information may also include information about the State of Health (SOH) of the battery. In this case, even if the type of battery is the same, the battery characteristic information may be stored separately for each SOH size (for example, every 10%).

[0082] The first and second embodiments described above show examples in which battery characteristics are stored for each type of battery pack, but the disclosure is not limited thereto. Battery characteristics may be stored for each battery pack (for example, for each battery pack ID). Also, in the first embodiment, battery characteristics may not be stored for each vehicle type, but rather for each vehicle (for each vehicle ID).

[0083] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of this disclosure is indicated by the claims rather than by the description of the embodiments above, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
