[0003] Although not described in Japanese Unexamined Patent Application Publication No. 2023-101504 mentioned above, the battery pack mounted on the vehicle by battery replacement may not be limited to a specific type of battery pack. Therefore, a battery pack inappropriate for the vehicle may sometimes be mounted on the vehicle. In this case, there is a risk of deterioration of vehicle performance.
[0004] 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 deterioration of vehicle performance caused by a battery pack mounted by battery replacement.
[0005] A first aspect of the present disclosure is a control device for controlling an electric vehicle equipped with a replaceable battery, the control device including:
[0006] a communication unit capable of receiving information stored in a storage device; and
[0007] a processor,
[0008] The storage device stores battery characteristic information indicating characteristics of the battery during driving of the electric vehicle in association with battery unique information unique to the battery,
[0009] The processor is configured to perform the following operations:
[0010] When the battery is replaced,
[0011] obtain, via the communication unit, battery characteristic information corresponding to the battery unique information of the replaced battery from the storage device,
[0012] change vehicle control in the electric vehicle using the battery characteristic information obtained from the storage device.
[0013] In the control device according to the first aspect of the present disclosure, as described above, when the battery is replaced, the processor obtains battery characteristic information corresponding to the battery unique information of the replaced battery and uses the obtained battery characteristic information to change vehicle control in the electric vehicle. Thus, it is 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 deterioration of vehicle performance caused by a battery pack mounted by battery replacement.
[0014] In the control device of the first aspect described above,
[0015] When the processor changes the vehicle control using the battery characteristic information corresponding to the replaced battery, the processor may also notify the user of the electric vehicle of the information on the change in the vehicle control.
[0016] If configured in this way, the user can recognize that the vehicle control has changed due to the replacement of the battery.
[0017] In the control device of the first aspect described above,
[0018] The processor may also notify the user of the information on the change by sending the information on the change to at least one of the display device mounted on the electric vehicle and the user terminal owned by the user.
[0019] If configured in this way, the user can visually recognize the information on the change, so the change in the vehicle control can be easily conveyed to the user.
[0020] In the control device of the first aspect described above,
[0021] The processor may also be configured to perform the following operations:
[0022] When the battery characteristic information corresponding to the replaced battery is stored in the storage device,
[0023] Based on the battery characteristic information corresponding to the replaced battery stored in the storage device, determine whether it is necessary to change the vehicle control,
[0024] When it is determined that it is necessary to change the vehicle control, change the vehicle control, and when it is determined that it is not necessary to change the vehicle control, maintain the current vehicle control,
[0025] When the battery characteristic information corresponding to the replaced battery is not stored in the storage device, maintain the current vehicle control.
[0026] If configured in this way, the vehicle control can be changed only when it is determined based on the battery characteristic information stored in the storage device that it is necessary to change the vehicle control.
[0027] A second aspect of the present disclosure is a control method for controlling an electric vehicle equipped with a replaceable battery, wherein the control method includes the following steps:
[0028] Obtain battery characteristic information corresponding to the battery unique information of the replaced battery from a storage device that stores the battery characteristic information representing the characteristics of the battery during driving of the electric vehicle in association with the battery unique information unique to the battery; and
[0029] When the battery is replaced, the vehicle control of the electric vehicle is changed using the battery characteristic information corresponding to the replaced battery obtained in the above-obtained process.
[0030] In the control method of 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, a control method capable of suppressing a decrease in vehicle performance due to the battery pack mounted by battery replacement can be provided.
[0031] According to the present disclosure, a decrease in vehicle performance due to the battery pack mounted by battery replacement can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Next, with reference to the accompanying drawings, embodiments of the present disclosure will be described in detail. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and their description will not be repeated. [First Embodiment]
[0043] <Structure of Battery Replacement System>
[0044] Figure 1 FIG. 9 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. In addition, the server 200 is an example of the "storage device" of the present disclosure.
[0045] The electric vehicle 100 includes a vehicle electronic control unit (ECU) 10, a data communication module (DCM) 20, a battery pack 30, and a car navigation device 40. The battery pack 30 can be replaced in the battery replacement device 300. In addition, the vehicle ECU 10 and the battery pack 30 are examples of the "control device" and the "battery" of the present disclosure, respectively.
[0046] In addition, the user of the electric vehicle 100 has a user terminal 150 (e.g., a smart phone).
[0047] The electric vehicle 100 is, for example, a plug-in hybrid electric vehicle (PHEV), a battery electric vehicle (BEV), or a fuel cell electric vehicle (FCEV).
[0048] 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 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 (e.g., information on the type of battery) is stored in the battery ECU 31.
[0049] The DCM 20 is configured to be able to communicate with a communication device outside the vehicle. The DCM 20 can communicate with the server 200 (the communication unit 230 described later). The DCM 20 may also be able to communicate with the user terminal 150.
[0050] The car navigation device 40 displays various information (e.g., map information and video content) on the display screen and announces various information (e.g., traffic information and weather information, etc.) by voice.
[0051] The vehicle ECU 10 includes a processor 1, a memory 2, and a communication unit 3. In the memory 2, in addition to the programs executed by the processor 1, information used in the programs (such as maps, formulas, and various parameters) is also stored.
[0052] The communication unit 3 communicates with the DCM 20, the battery ECU 31, and the car navigation device 40 respectively, for example, through CAN (Controller Area Network) communication.
[0053] The server 200 includes a processor 210, a memory 220, and a communication unit 230. In the memory 220, in addition to the programs executed by the processor 210, information used in the programs (such as maps, formulas, and various parameters) is also stored.
[0054] In the memory 220, there is stored Figure 2 the shown table 221. In the table 221, the battery type, the vehicle model, and the battery characteristics are stored in an associated manner. The information of the battery type (hereinafter referred to as the battery inherent information) includes the information of the battery manufacturer and the information of the battery model. The information of the vehicle model (hereinafter referred to as the vehicle information) includes the information of the vehicle manufacturer and the information of the vehicle model. The battery characteristic information represents the characteristics of the battery pack during vehicle driving (such as during driving and charging). In addition, the information of the battery type is an example of the "battery inherent information" of the present disclosure.
[0055] The information of the table 221 is made based on the information of the characteristics of the battery packs 30 of multiple electric vehicles including the electric vehicle 100 during driving (such as during driving and charging). 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 of the electric vehicle 100 during driving (information such as output voltage, output power, and battery temperature) are sent from the electric vehicle 100 to the server 200. Then, based on the information from the electric vehicle 100, the information of the table 221 stored in the memory 220 of the server 200 (the battery characteristic information corresponding to the battery inherent information of type B of manufacturer A and the vehicle information of type F of manufacturer E) is updated. In addition, when the battery characteristic information corresponding to the battery inherent information of type B of manufacturer A and the vehicle information of type F of manufacturer E is not stored in the memory 220, the information from the electric vehicle 100 is newly registered in the memory 220.
[0056] The communication unit 230 is configured to be able to communicate with the DCM 20 of the electric vehicle 100. In addition, the communication unit 230 may also be able to communicate with the user terminal 150.
[0057] Refer again to Figure 1 Figure 1 , the battery replacement device 300 includes a battery replacement device main body 300a for performing battery replacement and a storage 300b for storing the battery pack 30. In the storage 300b, various types of battery packs 30 are sometimes stored. The battery replacement device main body 300a is a device for performing battery replacement that replaces the battery pack 30 mounted on the electric vehicle 100 with the battery pack 30 stored in the storage. The storage 300b is attached to the battery replacement device main body 300a. At the battery replacement device 300 (battery replacement device main body 300a), there is provided an entrance / exit 302 for the electric vehicle 100 to enter and exit.
[0058] Here, in the conventional battery replacement system, the battery pack mounted on the vehicle through battery replacement is sometimes not limited to a specific type of battery pack. Therefore, a battery pack inappropriate for the vehicle is sometimes mounted on the vehicle.
[0059] Therefore, in the first embodiment, when the battery pack 30 is replaced, the processor 1 obtains, via the communication unit 3, the battery characteristic information corresponding to the battery unique information of the replaced battery pack 30 from the server 200 (memory 220). Specifically, the processor 1 obtains the battery characteristic information corresponding to the battery unique information of the replaced battery pack 30 and the vehicle information of the electric vehicle 100 from the server 200.
[0060] Then, the processor 1 uses the battery characteristic information obtained from the server 200 to change the vehicle control in the electric vehicle 100. For example, when the battery characteristic information includes information indicating a large increase in the battery temperature during driving of the electric vehicle 100, the processor 1 can reduce the maximum value of the output power (voltage) of the battery compared to normal times (e.g., a reference value determined according to the specifications, etc.).
[0061] <Regarding the control method for changing vehicle control>
[0062] Next, refer to Figure 3 and Figure 4 to describe the control method for changing the vehicle control of the electric vehicle 100.
[0063] Figure 3 Shows the timing when updating the information of the server 200 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 S10.
[0064] In S11, the vehicle ECU 10 sends data on the battery characteristics (such as battery output, battery voltage, and battery temperature) of the battery pack 30 during the running of the electric vehicle 100 to the server 200 via the DCM 20. Specifically, the processor 1 of the vehicle ECU 10 obtains the above data from the battery ECU 31 via the communication unit 3 of the vehicle ECU 10. Then, the processor 1 sends the above data to the DCM 20 via the communication unit 3, and sends the above data to the server 200 via the DCM 20. At this time, the vehicle information of the electric vehicle 100 may also be sent to the server 200.
[0065] In S12, the vehicle ECU 10 determines whether the running of the electric vehicle 100 has stopped. For example, the vehicle ECU 10 may also determine whether the running of the electric vehicle 100 has stopped based on changes in the position information of the electric vehicle 100 obtained by a GPS (not shown), changes in detection values of an acceleration sensor (speed sensor, etc.) (not shown), and the like. When the running of the electric vehicle 100 has stopped (Yes in S12), the processing of the electric vehicle 100 ends. When the running of the electric vehicle 100 has not stopped (No in S12), the process returns to S11.
[0066] In S20, the server 200 accumulates (stores) the data of S11 in association with the battery unique information of the battery pack 30 and the vehicle information of the electric vehicle 100. The above data may also be accumulated in the memory 220.
[0067] In S21, the server 200 determines whether 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 also determine that the electric vehicle 100 has stopped based on changes in the position information of the electric vehicle 100. When it is determined that the running of the electric vehicle 100 has stopped, the process proceeds to S22. When it is determined that the running of the electric vehicle 100 has not stopped, the process returns to S20.
[0068] In S22, the server 200 uses the data of S11 to perform data analysis for each combination of the battery unique information and the vehicle information.
[0069] In S23, the server 200 updates the battery characteristic information associated with the battery unique information. Specifically, the server 200 updates the battery characteristic information corresponding to the combination of the battery unique information and the vehicle information obtained by performing data analysis in S22 based on the analysis result of S22. In addition, when the battery characteristic information corresponding to the above combination is not stored in the server 200 at the time point of S23, the information based on the analysis result of S22 is newly registered in the memory 220.
[0070] Figure 4 This is a diagram showing the timing for changing the vehicle control of the electric vehicle 100 based on the battery characteristic information stored in the server 200. In S30, it is assumed that the battery pack 30 of the electric vehicle 100 has been replaced in the battery replacement device 300.
[0071] In S31, the vehicle ECU 10 receives the battery unique information of the replaced battery pack 30 from the battery ECU 31 via the communication unit 3.
[0072] In S32, the vehicle ECU 10 sends the battery unique information of the replaced battery pack 30 obtained in S31 to the server 200 via the DCM 20. Specifically, the processor 1 of the vehicle ECU 10 sends the battery unique information to the DCM 20 via the communication unit 3 of the vehicle ECU 10, and the battery unique information is sent to the server 200 via the DCM 20. In addition, in S32, the electric vehicle 100 may also send the vehicle information of the electric vehicle 100 to the server 200.
[0073] In 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 S32 is stored in the memory 220. That is, the server 200 determines whether there is an actual record of obtaining the battery characteristic data 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 S41. If the battery characteristic information is not stored (No in S40), the process proceeds to S42.
[0074] In S41, the server 200 sends 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. Thereafter, the control of the server 200 ends.
[0075] In S42, the server 200 sends information indicating that the battery characteristic information corresponding to the replaced battery pack 30 and the vehicle information of the electric vehicle 100 is not stored in the memory 220 (information indicating no data) to the electric vehicle 100. In addition, the above information indicating no data may also be sent to the user terminal 150. Thereafter, the control of the server 200 ends.
[0076] In S33, the vehicle ECU 10 determines whether it has received the battery characteristic information of S41. That is, the vehicle ECU 10 determines whether there has been an actual result of the combination of the battery inherent information of the replaced battery pack 30 and the vehicle information of the electric vehicle 100 in the past. When the battery characteristic information is received (Yes in S33), the process proceeds to S34. When the battery characteristic information is not received (when the notification of S42 is received) (No in S33), the process proceeds to S36.
[0077] In S34, based on the battery characteristic information received in S33, the vehicle ECU 10 determines whether vehicle control needs to be changed. For example, the vehicle ECU 10 can also compare the output power, output voltage, temperature characteristics, etc. in the replaced battery pack 30 included in the battery characteristic information with the allowable values set in the electric vehicle 100 to make the above determination. When vehicle control needs to be changed (Yes in S34), the process proceeds to S35. When vehicle control does not need to be changed (No in S34), the process proceeds to S36.
[0078] In S35, the vehicle ECU 10 changes the vehicle control based on the determination result in S34. Specifically, the vehicle ECU 10 changes control parameters, thresholds, 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 SOC (State Of Charge), charging time, cruising range, and power consumption rate, etc. in the replaced battery pack 30. Next, the process proceeds to S37.
[0079] In S36, the vehicle ECU 10 maintains the current vehicle control. In other words, the vehicle ECU 10 does not change the vehicle control. After that, the control of the vehicle ECU 10 ends.
[0080] The vehicle ECU 10 notifies the user of the electric vehicle 100 of the information on the change of the vehicle control in S35.
[0081] Specifically, in S37, the processor 1 of the vehicle ECU 10 sends the information on the change of the vehicle control to the car navigation device 40 through the communication unit 3.
[0082] Next, in S38, the processor 1 of the vehicle ECU 10 causes the information in S37 to be displayed on the car navigation device 40. Specifically, the processor 1 sends an instruction signal for displaying the above information to the car navigation device 40 through the communication unit 3.
[0083] Figure 5 An example of the image displayed on the car navigation device 40 in S38 is shown. InFigure 5 In the example shown, in the vehicle navigation device 40 of the vehicle, the battery-specific information, usage actual performance, battery characteristics, and evaluations made by the user of the replaced battery pack 30 are displayed. In addition, in the vehicle navigation device 40, the content that has been changed by the change of the vehicle control is displayed. In Figure 5 the example shown, the information on the output power of the battery pack 30 in normal times (before the change) is displayed (refer to Figure 5 the dashed line), and the information on the output power of the battery pack 30 after the change of the vehicle control ( Figure 5 the hatched part).
[0084] In Figure 5 the example shown, the change in the output power of the battery pack 30 (the change in the vehicle control) is represented by the change in the length of the displayed gauge bar. In addition, the change in the vehicle control can also be represented by the change in the display form of the icon.
[0085] As described above, in the first embodiment, when the battery pack 30 is replaced, the processor 1 acquires the battery characteristic information corresponding to the battery-specific information of the replaced battery pack 30 from the server 200, and uses the acquired battery characteristic information to change the vehicle control in the electric vehicle 100. Thus, since the electric vehicle 100 is controlled based on the battery characteristic information of the replaced battery pack 30, it is possible to suppress the execution of vehicle control that is inappropriate for the replaced battery pack 30. As a result, it is possible to suppress the performance degradation of the electric vehicle 100 due to the battery pack 30 mounted by battery replacement.
[0086] In addition, in the first embodiment, the server 200 performs data analysis based on the battery characteristic information acquired from the respective electric vehicles 100. Thus, it is possible to easily increase the amount of data used for analysis, and therefore, it is possible to obtain (calculate) more effective (more reliable) battery characteristic information for suppressing the performance degradation of the electric vehicle 100. [Second Embodiment]
[0087] Next, with reference to Figures 6 to 9 , the structure of the second embodiment will be described. Different from the first embodiment in which the battery replacement system 900 includes the server 200 and the electric vehicle 100, the battery replacement system 910 of the second embodiment does not include a server. In addition, for the same structure as the above first embodiment, the same reference numerals are added and no repeated description is made.
[0088] <Structure of Battery Replacement System>
[0089] Figure 6 is a diagram showing a battery replacement system 910 including an electric vehicle 100A and a battery replacement device 300 according to the second embodiment.
[0090] The electric vehicle 100A is different from the electric vehicle 100 of the first embodiment above in that the vehicle ECU 10A is included to replace the vehicle ECU 10. In addition, the vehicle ECU 10A is an example of the "control device" of the present disclosure.
[0091] The vehicle ECU 10A includes a processor 1A, a memory 2A, and a communication unit 3A. In the memory 2A, in addition to storing programs executed by the processor 1A, information used in the programs (for example, maps, formulas, and various parameters) is also stored. In addition, the memory 2A is an example of the "storage device" of the present disclosure.
[0092] Stored in the memory 2A is Figure 7 the shown table 2B. In the table 2B, battery characteristic information is stored in association with 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 (such as during driving and charging).
[0093] <Regarding the control method for changes in vehicle control>
[0094] Next, with reference to Figure 8 and Figure 9 , the control method for changes in the vehicle control of the electric vehicle 100A will be described. In addition, for steps that perform the same processing as in the first embodiment above, the same reference signs are added, and repeated descriptions will not be given.
[0095] Figure 8 Shows the timing when the information in the memory 2A is updated based on the battery characteristic information during the driving of the electric vehicle 100A.
[0096] In S11A, the vehicle ECU 10A accumulates the data of the battery characteristics of the battery pack 30 during the driving of the electric vehicle 100A in association with the battery-specific information of the battery pack 30.
[0097] In S12A, the vehicle ECU 10A determines whether the driving of the electric vehicle 100A has stopped. If it is determined that the driving of the electric vehicle 100A has stopped (Yes in S12A), the process proceeds to S13. If it is determined that the driving of the electric vehicle 100A has not stopped (No in S12A), the process returns to S11A.
[0098] In S13, the vehicle ECU 10A uses the data accumulated in S11A to perform data analysis for each battery-specific information.
[0099] In S14, the vehicle ECU 10A updates the battery characteristic information associated with the battery inherent information. Specifically, the vehicle ECU 10A updates the battery characteristic information corresponding to the battery inherent information obtained by performing data analysis in S13 based on the analysis result of S13. In addition, when the battery characteristic information corresponding to the above battery inherent information is not stored in the memory 2A at the time point of S14, the information based on the analysis result of S13 is newly registered in the memory 2A.
[0100] Figure 9 FIG. is a diagram showing the timing for changing the vehicle control of the electric vehicle 100A based on the battery characteristic information.
[0101] In S33A, the vehicle ECU 10A determines whether the battery characteristic information corresponding to the battery inherent information of S31 is stored in the memory 2A. That is, the vehicle ECU 10A determines whether there is an actual record of obtaining the battery characteristic data corresponding to the above battery inherent information in the electric vehicle 100A. When the battery characteristic information is stored (Yes in S33A), the process proceeds to S34. When the battery characteristic information is not stored (No in S33A), the process proceeds to S36.
[0102] In addition, regarding other structures and controls, they are the same as those in the above-described first embodiment, so repeated description will not be made.
[0103] As described above, in the second embodiment, the processor 1A of the vehicle ECU 10A executes the process of changing the vehicle control using the information stored in the memory 2A of the vehicle ECU 10A. Thus, the vehicle ECU 10A can 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. In addition, different from the case of communicating between an external device and the vehicle ECU (electric vehicle), the time required for communication (wireless communication) is not required, so the vehicle control can be changed relatively quickly.
[0104] In the above-described first embodiment, an example is shown in which the vehicle ECU 10 obtains the battery characteristic information stored in the server 200 and uses the obtained battery characteristic information to change the vehicle control (change control parameters, etc.), but the present disclosure is not limited thereto. For example, the server may also calculate control parameters for changing the vehicle control using the battery characteristic information stored in the server and send the above control parameters to the electric vehicle 100.
[0105] In the above-described first and second embodiments, an example is shown in which information regarding a change in vehicle control is displayed in the in-vehicle navigation device 40, but the present disclosure is not limited thereto. For example, information regarding a change in vehicle control may also be displayed in the user terminal 150.
[0106] In the above-described first and second embodiments, an example is shown in which a change in vehicle control is not performed when battery characteristic information corresponding to the replaced battery pack 30 is not stored in the server 200 (memory 2A), but the present disclosure is not limited thereto. Even in the above case, vehicle control may be changed based on information on the battery characteristics of the replaced battery pack 30.
[0107] In the above-described first and second embodiments, an example is shown in which data on battery characteristics during the running of an electric vehicle is accumulated, but the present disclosure is not limited thereto. For example, data on battery characteristics during charging and discharging of an electric vehicle may also be accumulated.
[0108] In the above-described first and second embodiments, an example is shown in which information regarding a change in vehicle control is displayed in the in-vehicle navigation device 40 or the like, but the present disclosure is not limited thereto. For example, information regarding a change in vehicle control may also be notified by sound from a speaker or the like.
[0109] In the above-described first and second embodiments, an example is shown in which the battery pack 30 is replaced, but the present disclosure is not limited thereto. A plurality of battery cells may also be replaced separately. In this case, battery characteristic information for each battery cell may also be managed in a server or the like.
[0110] In the above-described second embodiment, an example is shown in which the table 2B is stored in the memory 2A of the vehicle ECU 10A, but the present disclosure is not limited thereto. The table 2B may also be stored in a storage device different from the memory 2A provided in the electric vehicle 100A.
[0111] In the above-described first and second embodiments, an example is shown in which information regarding a change in vehicle control is notified to the user when the vehicle control is changed, but the present disclosure is not limited thereto. Information indicating that the vehicle control is not changed may also be notified to the user.
[0112] In the above-described first and second embodiments, an example is shown in which the battery unique information includes information on the type of the battery, but the present disclosure is not limited thereto. For example, the battery unique information may also include information on the SOH (State Of health) of the battery in addition to the information on the type of the battery. In this case, even if the types of the batteries are the same, the battery characteristic information may be stored separately according to the magnitude of the SOH (for example, for each 10%).
[0113] In the above-described first and second embodiments, an example is shown in which battery characteristics are stored for each type of battery pack. However, the present disclosure is not limited to this. Battery characteristics may also be stored for each battery pack (for example, for each battery pack ID). Further, in the first embodiment, instead of storing battery characteristics for each vehicle model, battery characteristics may be stored for each vehicle (for each vehicle ID).
[0114] It should be considered that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the present disclosure is represented not by the description of the above embodiments but by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
