Description

Technical Field

[0001] The present disclosure relates to a control device, a server, a control system, and a control method. Background Art

[0002] Japanese Unexamined Patent Application Publication No. 2015-104225 discloses a charging device that charges a secondary battery. The charging device includes: a table storage unit that stores a table showing the correspondence between combinations of the temperature and the DC resistance of the secondary battery and charging conditions, a temperature detection unit that detects the temperature of the secondary battery, and a resistance detection unit that detects the DC resistance of the secondary battery.

[0003] The charging device charges the secondary battery according to the charging conditions corresponding to the detected temperature and DC resistance. Summary of the Invention

[0004] In the charging device described in Japanese Unexamined Patent Application Publication No. 2015-104225, charging conditions for the secondary battery are selected based on the detected values of the temperature and the DC resistance of the secondary battery. In this case, when an abnormality occurs in the temperature detection unit or the resistance detection unit, charging (power transmission) cannot be performed according to appropriate charging conditions.

[0005] The present disclosure has been made to solve the above technical problems, and an object thereof is to provide a control device, a server, a control system, and a control method that can suppress power transmission to a battery mounted on a vehicle under inappropriate conditions.

[0006] A control device according to a first aspect of the present disclosure is a control device that controls power transmission including at least one of charging and discharging of a battery, and includes: a device-side communication unit that communicates with an external device; and a processor that performs a process of acquiring identification information of the battery. The external device includes an external server that stores parameter information related to parameters for power transmission of a battery adapted to the identification information. The processor acquires, via the device-side communication unit, the parameter information adapted to the battery corresponding to the identification information from the external server. The control device controls the power transmission of the battery using the parameter information acquired by the processor.

[0007] As described above, the control device according to the first aspect of the present disclosure receives, from the external server, the parameter information adapted to the battery corresponding to the identification information, and uses the received parameter information to control the power transmission of the battery. Thereby, it is possible to suppress a situation where parameter information not adapted to the battery is used in power transmission. As a result, it is possible to suppress a situation where power transmission is performed on the battery under inappropriate conditions.

[0008] In the control device related to the first aspect described above, preferably, the battery includes: a battery that uses lithium iron manganese phosphate formed by recycling lithium iron phosphate used as an active material as the active material. The parameter information includes information on parameters used in power transmission that are preset according to the ratio of manganese to iron in the active material. Here, the capacity (charge-discharge capacity) of the lithium iron manganese phosphate ion battery varies according to the ratio of manganese to iron. Therefore, by performing power transmission using the parameter information preset according to the above ratio, power transmission can be performed under more appropriate conditions. In addition, the deviation of the above ratio in the recycled product is larger than that in the new product. Therefore, using the parameter information based on the above ratio in the power transmission of the recycled product is particularly effective for optimizing the conditions in power transmission.

[0009] In this case, preferably, the parameter information includes information on parameters preset according to the above ratio and the amount of impurities contained in the battery. Here, the capacity (charge-discharge capacity) of the lithium iron manganese phosphate ion battery also varies according to the amount of impurities contained. Therefore, by performing power transmission using the parameter information preset according to not only the above ratio but also the amount of impurities, power transmission can be performed under further more appropriate conditions.

[0010] Preferably, the control device related to the first aspect described above is mounted on a vehicle. In addition, when the ignition power supply of the vehicle changes to on, the processor performs the process of obtaining the above identification information. With such a configuration, each time the ignition power supply changes to on, the parameters of power transmission can be optimized. For example, during battery replacement, the ignition power supply is disconnected. Therefore, at the moment when the ignition power supply is turned on after the battery replacement is completed, the optimal parameters can be obtained.

[0011] Preferably, the control device related to the first aspect described above is mounted on a vehicle. When the processor is connected to a terminal that can be connected to the vehicle, it performs the process of obtaining identification information according to a signal from the terminal requesting the identification information. With such a configuration, the identification information can be obtained according to a signal from an external device. As a result, the identification information can be easily sent to the external device according to the above request.

[0012] Preferably, in the control device related to the first aspect described above, when the obtained identification information changes, the device-side communication unit sends the changed identification information to an external server. With such a configuration, each time the battery pack is replaced with another battery pack, the parameters corresponding to the other battery pack can be obtained.

[0013] The server related to the second aspect of the present disclosure is a server disposed outside the control device related to the first aspect. The server includes: a server-side communication unit that receives identification information of the battery; and a storage unit that stores parameter information related to parameters for power transmission adapted to the battery corresponding to the identification information. The server-side communication unit sends the parameter information adapted to the battery corresponding to the received identification information to the control device.

[0014] As described above, the server related to the second aspect of the present disclosure sends, through the server-side communication unit, the parameter information adapted to the battery corresponding to the identification information to the control device. Thereby, a server capable of suppressing a situation where the control device performs power transmission to the battery under inappropriate conditions can be provided.

[0015] The control system related to the third aspect of the present disclosure includes the control device related to the first aspect and the server related to the second aspect. Thereby, a control system capable of suppressing a situation where the control device performs power transmission to the battery under inappropriate conditions can be provided.

[0016] The control method related to the fourth aspect of the present disclosure is a control method for a control device that controls power transmission including at least one of charging and discharging of a battery, and includes: a step of obtaining identification information of the battery; a step of receiving, from an external server that stores parameter information related to parameters for power transmission adapted to the battery corresponding to the identification information, the parameter information adapted to the battery corresponding to the identification information; and a step of controlling power transmission of the battery using the received parameter information.

[0017] As described above, the control method related to the fourth aspect of the present disclosure receives the parameter information adapted to the battery corresponding to the identification information from an external server, and uses the received parameter information to control power transmission of the battery. Thereby, a control method capable of suppressing a situation where power transmission is performed to the battery under inappropriate conditions can be provided.

[0018] In the control method related to the fourth aspect, preferably, the battery includes: a battery that uses lithium iron manganese phosphate formed by recycling lithium iron phosphate used as an active material as the active material. The parameter information includes information on parameters used in power transmission preset according to the ratio of manganese to iron in the active material. Thereby, a control method particularly effective for optimizing the conditions in power transmission can be provided. The above and other objects, features, aspects and advantages of the present invention will become apparent from the following detailed description of the present invention in conjunction with the accompanying drawings.

[0021] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.

[0022] [First Embodiment] <Configuration of Control System> Figure 1 This is a diagram showing the configuration of the control system 1 according to the first embodiment. The control system 1 includes a control device 100, an intelligent center 200, and a battery information server 300. In addition, the intelligent center 200 is an example of the "external device" of the present disclosure. In addition, the battery information server 300 is an example of the "external device", "external server", and "server" of the present disclosure.

[0023] The control device 100 is mounted on the electric vehicle 110. The intelligent center 200 and the battery information server 300 are each devices provided outside the electric vehicle 110. The electric vehicle 110 includes, for example, a PHEV (Plug-in Hybrid Electric Vehicle), a BEV (Battery Electric Vehicle), or an FCEV (Fuel Cell Electric Vehicle). In addition, the electric vehicle 110 is an example of the "vehicle" of the present disclosure.

[0024] In addition to the control device 100, the electric vehicle 110 is also provided with a battery pack 20 and an HMI (Human Machine Interface) device 30. The control device 100 includes an ECU (Electronic Control Unit) 10 and a DCM (Data Communication Module) 40. In addition, the battery pack 20 and the DCM 40 are examples of the "battery" and the "device-side communication unit" of the present disclosure, respectively.

[0025] The battery pack 20 stores electric power for driving the electric vehicle 110. A plurality of battery cells are housed in the battery pack 20. The battery pack 20 is provided on the electric vehicle 110 in such a manner that it can be replaced with another battery pack at a battery replacement device or a dealership (not shown). In addition, the battery cells of the battery pack 20 can be charged and discharged by being electrically connected to a power seat (not shown) or the like. In addition, each of charging and discharging is an example of the "power transmission" of the present disclosure.

[0026] The battery pack 20 includes, for example, an LMFP battery (lithium manganese iron phosphate battery). The LMFP battery of the battery pack 20 is formed, for example, by recycling an LFP battery (lithium iron phosphate battery). Specifically, the LMFP battery includes a battery that uses lithium manganese iron phosphate formed by recycling lithium iron phosphate used as an active material in the LFP battery as an active material. In addition, the configuration (material) of the battery pack 20 is not limited to the above example. For example, the battery pack 20 may include an LFP battery or may include a ternary battery.

[0027] The HMI device 30 includes, for example, a display terminal such as a car navigation system. The HMI device 30 displays prescribed information (maps, video content, various alarms, etc.) on the above display terminal.

[0028] The DCM 40 is configured to be able to communicate with the smart center 200 and the battery information server 300, respectively. Thus, the electric vehicle 110 can exchange various information with the smart center 200 and the battery information server 300, respectively, via the DCM 40.

[0029] The ECU 10 includes a processor 11, a memory 12, and a communication unit 13. In the memory 12, in addition to the programs executed by the processor 11, information used in the programs (for example, maps, formulas, and various parameters) is also stored. In addition, the processor 11 performs processing to obtain various information (for example, the battery pack ID described later) via the communication unit 13.

[0030] The communication unit 13 is configured to be able to perform CAN (Controller Area Network) communication with various ECUs (not shown) provided in the electric vehicle 110. For example, the communication unit 13 obtains the ID information of the battery pack 20 (hereinafter referred to as the battery pack ID) by performing CAN communication with the ECU (battery computer) provided on the battery pack 20. The battery pack ID is recorded in a memory (not shown) or the like of the battery pack 20. In addition, the battery pack ID is an example of the "identification information" of the present disclosure.

[0031] The battery information server 300 includes a processor 310, a memory 320, and a communication unit 330. In the memory 320, in addition to the programs executed by the processor 310, information used in the programs (for example, maps, formulas, and various parameters) is also stored. In addition, the memory 320 and the communication unit 330 are examples of the "storage unit" and the "server-side communication unit" of the present disclosure, respectively.

[0032] Specifically, charge and discharge parameters (hereinafter referred to as charge and discharge parameters) adapted to each of the multiple battery packs registered in the battery information server 300 are stored in the memory 320. The battery pack ID of each battery pack is stored in the memory 320 in association with the charge and discharge parameters (parameter 1 and parameter 2). In addition, the charge and discharge parameters include, for example, information such as charge and discharge voltage, charge and discharge current (charge and discharge speed), and thresholds used in temperature management and current (voltage) management in the battery. In addition, the charge and discharge parameters are an example of the "parameter information" of the present disclosure.

[0033] The charge and discharge parameters are values determined by inspection during the manufacturing (recycling process) of the battery pack. Specifically, in the battery information server 300, the ratio of manganese (Mn) to iron (Fe) in the active material of the LMFP battery formed by recycling the LFP battery is managed. In addition, in the battery information server 300, the amount of impurities and additive materials contained in the LMFP battery is also managed. The charge and discharge parameters are values determined for each LMFP battery based on the above ratios and impurity amounts of each LMFP battery. In addition, the charge and discharge parameters can also be determined for each manufacturing batch of the battery pack, or for each vehicle model.

[0034] Here, although the battery pack of the electric vehicle is sometimes replaced with another battery pack, the charge and discharge parameters adapted to the battery pack before replacement are still used. In this case, charging and discharging are performed using charge and discharge parameters that are not adapted to the replaced battery pack. As a result, for example, since charging and discharging are not performed within an appropriate voltage range, problems such as smooth charging and discharging not being possible may occur. For example, as Figure 3As shown, there are differences in the relationship between the potential (operating potential) and the charge-discharge capacity between the LFP battery and the LMFP battery. Specifically, the potential of the LMFP battery is higher than that of the LFP battery.

[0035] In addition, among the LMFP batteries, due to differences in the ratio of manganese to iron and the amount of impurities, the above relationship also varies. Figure 4 is a graph showing the relationship between the charge-discharge capacity and the number of charge-discharge cycles of the above-mentioned respective ratios. In Figure 4 it is shown that: compared with the LMFP batteries with a manganese-to-iron ratio of 75:25 or 80:20, the deterioration of the charge-discharge capacity of the LMFP battery with the above ratio of 70:30 with respect to the number of charge-discharge cycles is the smallest. In addition, the deterioration of the charge-discharge capacity of the LMFP battery with the above ratio of 75:25 with respect to the number of charge-discharge cycles is smaller than that of the LMFP battery with the above ratio of 80:20.

[0036] Thus, in the first embodiment, the DCM 40 of the electric vehicle 110 sends the battery pack ID acquired by the communication unit 13 to the battery information server 300. The processor 11 acquires, through the DCM 40, the charge-discharge parameters adapted to the battery pack 20 corresponding to the battery pack ID from the battery information server 300. The control device 100 (ECU 10) controls the charge and discharge of the battery pack 20 using the charge-discharge parameters acquired by the processor 11. For details, refer to Figure 5 the timing diagram of

[0037] <Control Method of Control System> Figure 5 is a timing diagram showing the control among the battery information server 300, the smart center 200, and the electric vehicle 110 (control device 100) in the control system 1. Figure 5 Each control of the battery information server 300 in Figure 5 is executed by the processor 310.

[0038] In step S1, the electric vehicle 110 determines whether the ignition power supply of the electric vehicle 110 has changed to on. That is, the electric vehicle 110 determines whether the operation button of the ignition power supply has been operated by the user to turn on the ignition power supply. If the ignition power supply is on (yes in S1), the process proceeds to step S2. If the ignition power supply is not on (no in S1), the process proceeds to step S9.

[0039] In step S2, the electric vehicle 110 performs a process of obtaining (reading) the battery pack ID of the battery pack 20 through CAN communication of the communication unit 13. Specifically, the communication unit 13 receives information on the battery pack ID from the battery computer of the battery pack 20 through CAN communication.

[0040] In step S3, the electric vehicle 110 determines whether the battery pack ID has changed. Specifically, the electric vehicle 110 determines whether the battery pack ID read in S2 is different from the battery pack ID read last time. If the battery pack ID has changed (Yes in S3), the process proceeds to step S4. If the battery pack ID has not changed (No in S3), the process proceeds to step S9.

[0041] In step S4, the electric vehicle 110 sends the information on the battery pack ID read in step S2 to the smart center 200 through the DCM 40.

[0042] In step S5, the smart center 200 sends the information on the battery pack ID sent from the electric vehicle 110 in step S4 to the battery information server 300.

[0043] In step S6, the battery information server 300 selects charge and discharge parameters corresponding to the battery pack ID sent from the smart center 200 in step S5 according to the information stored in the memory 320 (refer to Figure 2 ).

[0044] In step S7, the battery information server 300 sends the information on the charge and discharge parameters selected in step S6 to the electric vehicle 110 (DCM 40) through the communication unit 330. Additionally, the information on the charge and discharge parameters may also be sent to the electric vehicle 110 via the smart center 200.

[0045] In step S8, the electric vehicle 110 updates (changes) the currently set charge and discharge parameters to the charge and discharge parameters sent from the battery information server 300 in step S7.

[0046] In step S9, the electric vehicle 110 determines whether to perform charging or discharging. For example, the electric vehicle 110 determines to perform charging or discharging based on a situation such as receiving an instruction from the user to perform charging or discharging, or the charge and discharge connector being connected to the electric vehicle 110. If it is necessary to perform charging or discharging (Yes in S9), the process proceeds to step S10. If charging or discharging is not performed (No in S9), the process returns to step S1.

[0047] In step S10, the electric vehicle 110 performs charging or discharging according to the set charge-discharge parameters. Specifically, when the process of step S8 has been performed, the electric vehicle 110 uses the updated charge-discharge parameters to perform charging or discharging. On the other hand, when the process of step S8 has not been performed, the electric vehicle 110 uses the current (held at the time of step S1) charge-discharge parameters to perform charging or discharging. Then, the process ends.

[0048] As described above, in the first embodiment, the electric vehicle 110 sends the acquired battery pack ID to the battery information server 300, and receives information on charge-discharge parameters adapted to the battery pack 20 corresponding to the battery pack ID from the battery information server 300. Then, the electric vehicle 110 uses the received information on the charge-discharge parameters to control the charging or discharging of the battery pack 20. Thus, even if the type of the battery pack 20 is changed due to battery replacement or the like, charging and discharging can be performed using charge-discharge parameters suitable for the changed type of the battery pack 20. As a result, the battery pack 2 can be charged and discharged appropriately (e.g., efficiently).

[0049] [Second Embodiment] Next, with reference to Figure 6 and Figure 7 , a second embodiment of the present disclosure will be described. In the second embodiment, different from the first embodiment in which the exchange of information on the battery pack ID and the charge-discharge parameters is performed through communication via the DCM 40, the above information is exchanged through an information terminal 400 provided in a facility such as a dealership. In addition, for the same configuration as that of the first embodiment, the same reference numerals as those of the first embodiment are given, and redundant description will not be repeated.

[0050] <Configuration of Control System> Figure 6 is a diagram showing the configuration of a control system 2 according to the second embodiment. The control system 2 includes a control device 100A, an information terminal 400, a diagnostic tool 410, and a battery information server 300A. The information terminal 400 can be connected to the electric vehicle 110A via the diagnostic tool 410. In addition, the diagnostic tool 410 is an example of the "external device" of the present disclosure. In addition, the information terminal 400 is an example of the "external device" and "terminal" of the present disclosure. In addition, the battery information server 300A is an example of the "external server", "external device", and "server" of the present disclosure.

[0051] The control device 100A is mounted on the electric vehicle 110A. The information terminal 400 and the diagnostic tool 410 are each devices provided outside the electric vehicle 110A. The electric vehicle 110A is different from the electric vehicle 110 of the above first embodiment in that it has a control device 100A instead of the control device 100. In addition, the DCM 40 may not be provided in the control device 100A. The electric vehicle 110A is an example of the "vehicle" of the present disclosure.

[0052] The control device 100A includes an ECU 10A. The ECU 10A has a processor 11A, a memory 12A, and a communication unit 13A. In the memory 12A, in addition to the programs executed by the processor 11A, information used in the programs (for example, maps, formulas, and various parameters) is also stored. In addition, the communication unit 13A is an example of the "device-side communication unit" of the present disclosure.

[0053] The battery information server 300A includes a processor 310A, a memory 320A, and a communication unit 330A. In the memory 320A, in addition to the programs executed by the processor 310A, information used in the programs (for example, maps, formulas, and various parameters) is also stored. In addition, the memory 320A and the communication unit 330A are examples of the "storage unit" and the "server-side communication unit" of the present disclosure, respectively.

[0054] In the memory 320A, in the same manner as the memory 320 of the above first embodiment (refer to Figure 2 ), the battery pack IDs and the charge and discharge parameters are stored in an associated manner.

[0055] The information terminal 400 and the diagnostic tool 410 are each devices provided in a dealer, a vehicle repair factory, a battery replacement facility, etc. The diagnostic tool 410 is connected to the electric vehicle 110A through a cable 420, thereby diagnosing whether there is an abnormality in the electric vehicle 110A. At this time, the information of the battery pack ID is extracted from the electric vehicle 110A by the diagnostic tool 410. In addition, when the electric vehicle 110A (processor 11A) is connected to the information terminal 400 (diagnostic tool 410), the process of acquiring the battery pack ID is performed according to the signal from the information terminal 400 that requests the information of the battery pack ID. The information of the battery pack ID extracted by the diagnostic tool 410 is sent to the information terminal 400 connected to the diagnostic tool 410 through a cable 430. The information of the battery pack ID acquired by the information terminal 400 is sent to the battery information server 300A through communication. In addition, information is exchanged between the information terminal 400 and the electric vehicle 110A (communication unit 13A) through CAN communication.

[0056] <Control method of the control system> Figure 7It is a timing chart showing the control among the battery information server 300, the information terminal 400, and the electric vehicle 110A in the control system 2. Figure 7 Each control of the battery information server 300A in Figure 7 is executed by the processor 310A. Figure 7 Each control of the electric vehicle 110A in Figure 7 is executed by the control device 100A (ECU 10A (processor 11A)). Additionally, for the same processes as those in the sequence in the above first embodiment (refer to Figure 5 ), the same reference numerals are assigned, and duplicate explanations are not provided.

[0057] In step S21, the information terminal 400 sends a signal for requesting the battery pack ID information to the electric vehicle 110A via the diagnostic tool 410. Additionally, the signal for requesting the battery pack ID can also be directly sent from the information terminal 400 to the electric vehicle 110A without passing through the diagnostic tool 410.

[0058] In step S22, the electric vehicle 110A determines whether the request signal in step S21 is received. If the request signal is received (Yes in S22), the process proceeds to step S2. If the request signal is not received (No in S22), the process proceeds to step S9.

[0059] When the result in step S3 is Yes, the process in step S14 is performed. In step S14, the electric vehicle 110A sends (notifies) the battery pack ID information to the information terminal 400 via the diagnostic tool 410 through the communication unit 13A. Additionally, the battery pack ID information can also be directly sent from the electric vehicle 110A to the information terminal 400 without passing through the diagnostic tool 410.

[0060] In step S23, the information terminal 400 sends the battery pack ID information sent from the electric vehicle 110A in step S14 to the battery information server 300A.

[0061] In step S24, the battery information server 300A sends the charge-discharge parameter information selected in step S6 to the information terminal 400 through the communication unit 330. Additionally, the charge-discharge parameter information can also be directly sent to the electric vehicle 110A.

[0062] In step S25, the information terminal 400 sends the information on the charge and discharge parameters sent from the battery information server 300A in step S24 to the electric vehicle 110A via the diagnostic tool 410. Additionally, the information on the charge and discharge parameters may be directly sent from the information terminal 400 to the electric vehicle 110A without going through the diagnostic tool 410. Moreover, the information on the charge and discharge parameters may be directly sent from the battery information server 300A (communication unit 330A) to the electric vehicle 110A (DCM 40). Then, the processing after step S8 is executed in the electric vehicle 110A.

[0063] Additionally, regarding other configurations and processes, since they are the same as those in the first embodiment described above, redundant explanations will not be provided.

[0064] In the first and second embodiments described above, an example is shown where an ID is set for each battery pack 20, but the present disclosure is not limited to this. For example, an ID may be set for each of the multiple battery cells housed in the battery pack. In this case, when each of the multiple battery cells is replaced, the charge and discharge parameter update process can be performed.

[0065] In the first and second embodiments described above, an example is shown where the charge and discharge parameters based on the ratio of manganese to iron and the impurity amount in the battery pack 20 are stored in the battery information server 300A (300A), but the present disclosure is not limited to this. Charge and discharge parameters determined in advance based on only one of the above ratio and the above impurity amount may be stored in the battery information server 300 (300A).

[0066] In the first and second embodiments described above, an example is shown where the control device 100 (100A) is mounted on the electric vehicle 110 (110A), but the present disclosure is not limited to this. For example, the control device may also be mounted on a power seat (EVSE: Electric Vehicle Supply Equipment) that charges (discharges) with the electric vehicle.

[0067] In the first and second embodiments described above, an example is shown where the electric vehicle 110 (110A) performs the process of obtaining (reading) the battery pack ID when the ignition power is turned on or when a request signal is received from the information terminal 400, but the present disclosure is not limited to this. For example, the electric vehicle may also perform the process of obtaining (reading) the battery pack ID based on the fact that a battery pack replacement process has been performed. In this case, since the default value (initial value) used in the battery deterioration determination is reconfirmed (optimized) due to the battery replacement, a decrease in the accuracy of the battery deterioration determination can be suppressed.

[0068] In the above-described first and second embodiments, an example is shown in which the control system 1(2) includes the intelligent center 200 and the battery information server 300(300A), but the present disclosure is not limited thereto. The control system may also include one server that integrates the intelligent center 200 and the battery information server 300(300A).

[0069] In the above-described first and second embodiments, an example is shown in which the electric vehicle 110(110A) can perform charging and discharging respectively, but the present disclosure is not limited thereto. For example, the electric vehicle may also be capable of only charging.

[0070] In the above-described first embodiment, an example is shown in which information on the battery pack ID and the charge / discharge parameters is respectively transmitted and received between the DCM 40 of the electric vehicle 110 and the battery information server 300, but the present disclosure is not limited thereto. At least one of the information on the battery pack ID and the charge / discharge parameters may also be transmitted and received between the battery information server 300 and the user's terminal (such as a smart phone).

[0071] In the above-described second embodiment, an example is shown in which the information terminal 400 is connected to the electric vehicle 110A via the diagnostic tool 410, but the present disclosure is not limited thereto. The information terminal 400 and the electric vehicle 110A may also be directly connected.

[0072] In the above-described first and second embodiments, an example is shown in which the LMFP battery formed by recycling the LFP battery is mounted on the electric vehicle 110(110A), but the present disclosure is not limited thereto.
