Summary of the Invention

Problems to be Solved by the Invention

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

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a battery swapping system and a battery capable of suppressing damage to the battery caused by vehicle control of an electric vehicle to be mounted by battery swapping.

Means for Solving the Problems

[0006] The battery replacement system according to the first aspect of the present disclosure includes an electric vehicle capable of battery replacement, a battery mounted on the electric vehicle, and a control device. The control device stores vehicle characteristic information indicating the characteristics of the electric vehicle during driving in association with the battery identification information of the battery, the battery characteristic information indicating the characteristics of the battery, and the vehicle identification information of the electric vehicle. When the battery is mounted on the electric vehicle, the control device generates battery information based on the battery characteristic information and the vehicle characteristic information corresponding to the vehicle identification information, and transmits the battery information to the electric vehicle.

[0007] In the control device according to the first aspect of the present disclosure, as described above, when the battery is mounted on the vehicle, the control device acquires vehicle characteristic information corresponding to the vehicle unique information of the vehicle after mounting. The control device generates battery information based on the battery characteristic information of the battery and the acquired vehicle characteristic information, and transmits the battery information to the electric vehicle. In this way, the battery transmits the battery information generated based on the vehicle characteristic information to the electric vehicle. Since the electric vehicle controls the vehicle according to the battery information acquired from the battery, it is possible to suppress the battery from being damaged by the vehicle control of the electric vehicle.

[0008] The battery replacement system according to the first aspect of the present disclosure further includes a battery replacement station in which the battery is stored. When transmitting the battery information to the electric vehicle, the battery notifies the user of the electric vehicle of the battery information.

[0009] With this configuration, the user can recognize the battery information of the battery mounted on the electric vehicle.

[0010] In the battery replacement system according to the first aspect of the present disclosure, the battery notifies the user of the battery information by transmitting the battery information to at least one of a display device mounted on the electric vehicle and a user terminal owned by the user.

[0011] With this configuration, since the user can visually recognize the battery information, the battery information of the battery mounted on the electric vehicle can be easily transmitted to the user.

[0012] In the battery swapping system according to the first aspect of the present disclosure, when vehicle characteristic information corresponding to the electric vehicle on which the battery is mounted is stored in the control unit, the battery determines whether it is necessary to generate battery information changed from the battery characteristic information based on the battery characteristic information and the vehicle characteristic information corresponding to the electric vehicle. When it is determined that it is necessary to generate battery information changed from the battery characteristic information, battery information is generated based on the battery characteristic information and the vehicle characteristic information, and the generated battery information is transmitted. When it is determined that it is not necessary to generate battery information changed from the battery characteristic information, the battery characteristic information is transmitted as the battery information. When vehicle characteristic information corresponding to the electric vehicle on which the battery is mounted is not stored in the control unit, the battery characteristic information is transmitted as the battery information.

[0013] With this configuration, the battery information changed from the battery characteristic information can be generated only when it is determined that it is necessary to generate the battery information changed from the battery characteristic information based on the vehicle characteristic information stored in the control unit.

[0014] The battery according to the second aspect of the present disclosure is a battery mounted on an electric vehicle capable of battery swapping, and includes a control device and a communication unit capable of communicating with the electric vehicle. The control device generates battery information based on vehicle characteristic information indicating the characteristics of the electric vehicle during driving of the electric vehicle, and the communication unit transmits the battery information to the electric vehicle.

[0015] With this configuration, the battery transmits the battery information generated based on the vehicle characteristic information to the electric vehicle. Since the electric vehicle controls the vehicle based on the battery information acquired from the battery, it is possible to suppress the use of the battery in such a way that the battery is damaged by the vehicle control of the electric vehicle.

Advantages of the Invention

[0016] According to the present disclosure, it is possible to suppress the battery mounted on the electric vehicle from being damaged due to vehicle control of the electric vehicle that deviates from the specifications of the battery when the battery is swapped.

Embodiments for Carrying Out the Invention

[0018] 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.

[0019] <Configuration of the Battery Replacement System> FIG. 1 is a diagram showing a battery replacement system.

[0020] The battery replacement system 1 includes an electric vehicle 100, a server 200, and a battery replacement device 300. 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). Note that the server 200 is an example of the "control device" of the present disclosure.

[0021] The electric vehicle 100 includes a vehicle body 10 and a battery 30. The vehicle body 10 is the part of the electric vehicle 100 other than the battery 30. It includes a vehicle ECU (Electronic Control Unit) 11, a communication device 12, an HMI device 13, an SMR 14, a drive device 15, and a terminal 19A. Note that the HMI device 13 is an example of the "display device" of the present disclosure.

[0022] The vehicle ECU 11 records information regarding the electric vehicle described later (hereinafter referred to as "vehicle identification information"). The vehicle ECU 11 is formed to be communicable with each of the communication device 12, the HMI device 13, the SMR 14, the drive device 15, and the battery ECU 31 via a communication unit 35 described later, for example, by CAN (Controller Area Network) communication. The vehicle ECU 11 controls the drive device 15 based on battery information acquired from the battery 30.

[0023] Note that the battery information includes, for example, at least some of the information indicating the upper limit input power (Winmax) of the battery 30, the upper limit output power (Woutmax), the allowable current value, the allowable voltage value, the upper limit output current, the upper limit input current, the upper limit voltage, the lower limit voltage, the lower limit SOC, the upper limit battery temperature, and the lower limit battery temperature.

[0024] The communication device 12 is formed to be communicable with the server 200 and the battery replacement device 300. Note that the communication device 12 may be communicable with a user terminal 150 such as a mobile phone owned by a user of the electric vehicle.

[0025] The HMI device 13 is mounted on the vehicle and displays various information (for example, map information and video content) on a display screen, and notifies various information (for example, traffic information and weather information, etc.) by voice. The HMI device 13 includes a display with a touch panel, a speaker, and the like.

[0026] The SMR 14 is provided between the drive device 15 and the battery 30. The SMR 14 is formed to be able to switch the electrical connection of the electrical circuit between the drive device 15 and the battery 30 in accordance with an instruction from the vehicle ECU 11. Note that "SMR" means a System Main Relay.

[0027] The drive device 15 includes an MG (Motor Generator) and a PCU (Power Control Unit) not shown in the figure. The drive device 15 is formed to be able to run the electric vehicle 100 using the power output from the battery 30.

[0028] The MG functions as a driving motor. The MG is electrically connected to the battery 30 via the PCU. The MG converts the power from the battery 30 into torque and rotates the drive wheels of the electric vehicle 100. Further, the MG performs regenerative power generation, for example, when the electric vehicle 100 decelerates, and charges the battery 30.

[0029] The PCU includes an inverter and a converter. The PCU supplies the power supplied from the battery 30 to the MG under the control of the vehicle ECU 11.

[0030] The terminal 19A is formed to be electrically connectable to the terminal 19B formed on the battery 101. The vehicle body 10 is formed to be electrically connectable to the battery 101 via the terminals 19A and 19B.

[0031] The battery 30 includes a battery ECU 31, a power storage module 32, a communication device 33, an SMR 34, and a terminal 19B. The battery 30 is formed to be replaceable in the battery replacement device 300. Note that the battery ECU 31 is an example of the "control device" of the present disclosure.

[0032] The battery ECU 31 records information regarding the battery 30 described later (hereinafter referred to as "battery-specific information"). The battery ECU 31 is formed to be communicable with each of the vehicle ECU 11 and the SMR 22, for example, by CAN communication, via a communication unit 35 described later. The battery ECU 31 is formed to be able to switch the connection of the SMR 22 based on an instruction from the vehicle ECU 11.

[0033] The power storage module 32 is a secondary battery such as, for example, a lithium-ion battery, a nickel-metal hydride battery, or a sodium-ion battery. The type of the secondary battery may be a liquid secondary battery or an all-solid-state secondary battery. The power storage module 32 is formed to be electrically connectable to the vehicle body 10 by connecting the terminal 19A and the terminal 19B.

[0034] The communication device 33 is configured to be communicable with the server 200 and the battery replacement device 300. The SMR 34 is provided between the power storage module 32 and the terminal 19B. The SMR 34 is configured to be able to switch the electrical connection of the electrical circuit between the power storage module 32 and the terminal 19B according to an instruction from the battery ECU 31. The communication unit 35 is configured such that the battery ECU 31 can communicate with the vehicle ECU 11.

[0035] The server 200 includes a processor 210, a memory 220, and a communication device 230. In the memory 220, in addition to the programs executed by the processor 210, information used in the programs (such as maps, mathematical formulas, and various parameters) is stored. The communication device 230 is configured to be communicable with the communication device 33.

[0036] The memory 220 stores the table 221 shown in FIG. 2. In the table 221, battery-specific information (including battery identification information and battery characteristic information), vehicle identification information, and vehicle characteristic information are recorded in association with each other.

[0037] The battery identification information that constitutes part of the battery-specific information includes information on the battery manufacturer related to the battery 30 and information on the battery model.

[0038] The battery characteristic information that constitutes part of the battery-specific information includes information indicating the upper limit input power (Winmax), upper limit output power (Woutmax), allowable current value, allowable voltage value, upper limit output current, upper limit input current, upper and lower limit voltages, lower limit SOC, and upper and lower limit battery temperatures of the battery 30. The vehicle identification information includes at least part of the information on the manufacturer of the electric vehicle 100 and the information on the model.

[0039] The vehicle characteristic information includes the vehicle characteristic information when the electric vehicle 100 is in operation (such as during driving and charging). More specifically, the vehicle characteristic information includes any one of information indicating the relationship between the temperature of the PCU during vehicle driving and the input power and output power of the battery 30, information indicating the input power, output power, voltage, current, remaining battery level, and battery temperature related to the battery 30 during vehicle driving, and information indicating the charging power, charging voltage, charging current, and battery temperature related to the battery 30 during charging. At least, the vehicle characteristic information includes information indicating the relationship between the temperature of the PCU during vehicle driving and the input power and output power of the battery 30.

[0040] The information in Table 221 is created based on the vehicle characteristic information of the electric vehicle 100 during the driving (such as during driving and charging) of each of a 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 30 of type B of manufacturer A. In this case, the vehicle characteristic information of the electric vehicle 100 during driving is transmitted from the battery 30 to the server 200. Then, the information in Table 221 stored in the memory 220 of the server 200 (the vehicle characteristic information corresponding to the battery-specific information of type B of manufacturer A and the vehicle identification information of type F of manufacturer E) is updated based on the information from the battery 30. If the vehicle characteristic information corresponding to the battery-specific information of type B of manufacturer A and the vehicle identification information of type F of manufacturer E is not stored in the memory 220, the information from the battery 30 is newly registered in the memory 220.

[0041] 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 compartment 300b where the battery 30 is stored. Various types of batteries 30 may be stored in the storage compartment 300b. The battery swapping device main body 300a is a device that performs battery swapping to replace the battery 30 mounted on the electric vehicle 100 with the battery 30 stored in the storage compartment. The storage compartment 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 (the battery swapping device main body 300a).

[0042] Here, the vehicles in which the battery is replaced in the battery replacement device 300 include various vehicles such as new cars, used cars, SUV types, and sports types. Therefore, depending on the vehicle, there are vehicles that, for example, cause the PCU to become hot during driving or charge beyond the upper limit charging power of the battery during charging. As a result, there is a risk that the vehicle itself or the battery may be damaged.

[0043] On the other hand, in the present embodiment, the battery ECU 31 acquires, through the communication device 33, vehicle characteristic information corresponding to the vehicle identification information of the electric vehicle 100 in which the battery 30 is mounted from the server 200 (memory 220) after the battery replacement.

[0044] Then, the battery ECU 31 generates battery information to be transmitted to the electric vehicle 100 using the battery characteristic information and the vehicle characteristic information acquired from the server 200.

[0045] For example, for the electric vehicle 100 so that the temperature of the PCU does not rise during driving, the battery 30 sets the upper limit output power of the battery information to be transmitted to the electric vehicle to be lower than the upper limit output power of the battery characteristic information, and transmits the battery information to the electric vehicle 100. The electric vehicle 100 sets the power supplied to the PCU and the like based on the upper limit output power of the received battery information. As a result, during driving, the current flowing through the PCU can be kept small, and the heat generation temperature of the PCU can be suppressed. Thereby, it is possible to suppress damage to the electric vehicle 100.

[0046] Also, for example, when the battery ECU 31 determines that the battery 30 is mounted on the electric vehicle 100 that performs vehicle control exceeding the allowable current of the battery during driving, or when it determines that the battery 30 is mounted on the electric vehicle 100 whose battery temperature deviates from the allowable range during driving, for example, the battery ECU 31 transmits battery information with the allowable current value set lower than the battery characteristic information to the vehicle ECU 11. Since the electric vehicle 100 performs vehicle control based on the acquired battery information, it is possible to suppress the implementation of vehicle control that exceeds the allowable current of the battery or the deviation of the battery temperature from the allowable range during driving of the vehicle.

[0047] <Control Method for Changing Battery Information> Next, with reference to FIGS. 3 and 4, a control method for generating battery information of the battery 30 will be described.

[0048] FIG. 3 shows a sequence when the information of the server 200 is updated based on the vehicle 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.

[0049] At step S11, the battery ECU 31 acquires vehicle identification information from the vehicle ECU 11.

[0050] At step S12, the battery ECU 31 transmits the battery unique information and the vehicle identification information to the server 200 through the communication device 33.

[0051] At step S13, the battery ECU 31 transmits data on the vehicle characteristics of the electric vehicle 100 during driving of the electric vehicle 100 (measured data such as the output power, voltage, current, remaining battery level, and temperature of the battery 30) to the server 200 through the communication device 33.

[0052] At step S14, the battery ECU 31 determines whether or not the driving of the electric vehicle 100 has stopped. If the driving of the electric vehicle 100 has stopped (Yes at step S14), the process of the battery 30 ends. If the driving of the electric vehicle 100 has not stopped (No at step S14), the process returns to step S13.

[0053] In step S15, the server 200 associates and stores (memorizes) the data of the vehicle characteristics with the battery unique information of the battery 30 and the vehicle identification information of the electric vehicle 100. The above data is stored in the memory 220.

[0054] In step S16, 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 battery ECU 31. If it is determined that the running of the electric vehicle 100 has stopped, the process proceeds to step S17. If it is determined that the electric vehicle 100 is still running, the process returns to step S15.

[0055] In step S17, the server 200 performs data analysis on all the past vehicle characteristic data stored in association with the battery unique information and the vehicle identification information. The data analysis result is synonymous with the vehicle characteristic information.

[0056] In step S18, the server 200 updates the battery characteristic information generated in step S17 from the existing battery characteristic information. Specifically, when there is already battery characteristic information corresponding to the combination of the battery unique information and the vehicle identification information in the memory 220, the server 200 updates the existing battery characteristic information to the battery characteristic information based on the analysis result of step S17. If there is no existing battery characteristic information, the vehicle characteristic information based on the analysis result of step S17 is newly registered in the memory 220.

[0057] FIG. 4 is a diagram showing a sequence for generating battery information of a battery based on vehicle characteristic information stored in a server. In step S110, it is assumed that the battery 30 of the electric vehicle 100 is replaced in the battery swapping device 300.

[0058] In step S115, the vehicle ECU 11 transmits the battery replacement completion signal and the vehicle identification information to the battery ECU 31. Note that step S115 does not necessarily start immediately after the battery replacement is completed (step S110). It may be appropriately started after the battery replacement is completed and during the running of the electric vehicle 100.

[0059] In step S120, the battery ECU 31 determines whether it has received the battery replacement completion signal and the vehicle identification information. If received (Yes in step S120), the process proceeds to step S125. If not received (No in step S120), the process returns to step S120.

[0060] In step S125, the battery ECU 31 transmits the battery unique information and the vehicle identification information to the server 200 via the communication device 33.

[0061] In step S130, the server 200 determines whether it has received the battery unique information and the vehicle identification information. If received (Yes in step S130), the process proceeds to step S135. If not received (No in step S130), the process returns to step S130.

[0062] In step S135, the server 200 determines whether the vehicle characteristic information corresponding to the battery unique information and the vehicle identification information is stored in the memory 220. If the vehicle characteristic information is stored (Yes in step S135), the process proceeds to step S145. If the vehicle characteristic information is not stored (No in step S135), the process proceeds to step S140.

[0063] In step S140, the server 200 transmits to the battery 30 a message indicating that the vehicle characteristic information corresponding to the battery unique information of the battery 30 and the vehicle identification information of the electric vehicle 100 on which the battery 30 is mounted is not stored in the memory 220. Note that the information indicating the absence of the above data may also be transmitted to the user terminal 150. Thereafter, the control of the server 200 ends.

[0064] In step S145, the server 200 transmits the battery-specific information of the battery 30 and the vehicle characteristic information corresponding to the vehicle identification information of the electric vehicle 100 on which the battery 30 is mounted to the electric vehicle 100. After that, the control of the server 200 ends.

[0065] In step S149, the battery ECU 31 determines whether it has received a notification indicating that there is no data. If a notification has been received (Yes in step S149), the process proceeds to step S160. If no notification has been received (No in step S149), the process proceeds to step S150.

[0066] In step S150, the battery ECU 31 determines whether it has received the vehicle characteristic information. That is, the battery ECU 31 determines whether there is a past record of the combination of the battery 30 and the electric vehicle 100 on which the battery 30 is mounted. If the vehicle characteristic information has been received (Yes in step S150), the process proceeds to step S155. If the vehicle characteristic information has not been received (No in step S150), the process returns to step S149.

[0067] In step S155, the battery ECU 31 determines whether the battery characteristic information can be transmitted as battery information based on the battery characteristic information and the vehicle characteristic information. For example, the battery ECU 31 makes the above determination by comparing the battery characteristic information of the battery 30 with the vehicle characteristic information. If the battery characteristic information can be transmitted as battery information (Yes in step S155), the process proceeds to step S160. If the battery characteristic information cannot be transmitted as battery information (No in step S155), the process proceeds to step S165.

[0068] In step S160, the battery ECU 31 transmits the battery characteristic information as battery information. After that, the control of the battery ECU 31 ends.

[0069] In step S165, the battery ECU 31 generates battery information with values changed from the battery characteristic information (such as the maximum input / output of the battery 30, upper and lower limit voltages, upper limit current, upper and lower limit SOC, etc.) based on the vehicle characteristic information. Specifically, the battery characteristic information is compared with the vehicle characteristic information. For example, when the electric vehicle 100 is driving beyond the threshold value of the allowable current value, the battery ECU 31 generates battery information with the allowable current value being the value obtained by subtracting the amount exceeding the threshold from the allowable current value included in the battery characteristic information.

[0070] In step S170, the battery ECU 31 transmits the battery information with the values of the battery characteristic information changed to the vehicle ECU 11. Thereafter, the control of the battery ECU 31 ends.

[0071] In step S175, the vehicle ECU 11 determines whether it has received the battery information from the battery ECU 31. The battery ECU 31 that has received the battery information controls the vehicle based on the battery information. If the battery information is received (Yes in step S175), the process proceeds to step S180. If the battery information has not been received (No in step S175), the process repeats step S175.

[0072] In step S180, the vehicle ECU 11 may display the battery information received from the battery ECU 31 on the HMI device 13 and notify the user of the electric vehicle 100 of the battery information. Note that the vehicle ECU 11 may also display the battery information received from the battery ECU 31 on the user terminal 150. Further, the vehicle ECU 11 may acquire the battery characteristic information from the battery ECU 31 and display it together with the battery information. Thereafter, the control of the vehicle ECU 11 ends.

[0073] As described above, in this embodiment, after the battery replacement is completed, the vehicle characteristic information corresponding to the vehicle identification information of the electric vehicle 100 equipped with the battery 30 is acquired from the server 200. Using the acquired vehicle characteristic information, the battery 30 generates battery information, and the battery 30 transmits the battery information to the vehicle ECU 11. The electric vehicle 100 controls the vehicle based on the battery information. Thereby, it is possible to suppress the electric vehicle 100 from deviating from the battery characteristic information of the battery 30 and controlling the vehicle. And it is possible to suppress the battery 30 from being damaged due to the control of the electric vehicle 100.

[0074] In this embodiment, the server 200 analyzes the vehicle characteristic data using the newly accumulated vehicle characteristic data after the vehicle stops running and updates the existing vehicle characteristic data. However, the present disclosure is not limited to this.

[0075] Even while the vehicle is running, the server 200 may analyze the vehicle characteristic data every time a certain amount of vehicle characteristic data is accumulated and update the existing vehicle characteristic information.

[0076] In this embodiment, the server 200 receives the data of the vehicle characteristics associated with the battery unique information and the vehicle identification information from the battery ECU 31, analyzes the data of the vehicle characteristics, and newly creates or updates the analyzed data (vehicle characteristic information). However, the present disclosure is not limited to this.

[0077] The battery ECU 31 may accumulate the data of the vehicle characteristics in association with the vehicle identification information, analyze the data of the vehicle characteristics, and newly create or update the analyzed data (vehicle characteristic information).

[0078] In this embodiment, the battery ECU 31 determines whether it is possible to transmit the battery characteristic information as battery information based on the vehicle characteristic information. If it is determined that there is, the battery ECU 31 creates the battery information with the value of the battery characteristic information changed based on the vehicle characteristic information. However, the present disclosure is not limited to this.

[0079] The server 200 determines whether it can transmit battery characteristic information as battery information based on vehicle characteristic information. If it determines that it can, the server 200 may create battery information with a value changed from the battery characteristic information based on the vehicle characteristic information. When the server 200 receives battery unique information and vehicle identification information from the battery 30, it may transmit the battery information instead of the vehicle characteristic information in step S145 of FIG. 4. In this case, the battery 30 may transmit the received battery information to the vehicle ECU 11 without determining whether it can transmit the battery characteristic information as battery information (step S155 in FIG. 5).

[0080] The embodiments disclosed herein should be considered as illustrative in all respects and not restrictive. The scope of the present disclosure is defined by the claims rather than the description of the above embodiments, and it is intended that all modifications within the meaning and scope equivalent to the claims be included.
