Description

Specimen testing system, temperature control device, specimen testing method, and specimen testing program

[0001] The present invention relates to a specimen testing system, a temperature adjustment device, a specimen testing method, and a specimen testing program.

[0002] Conventionally, as shown in Patent Document 1, in a testing device for an on-board battery, not only is a charging / discharging device used to charge / discharge a test sample under conditions that simulate actual use, but a constant temperature and humidity chamber is also used to charge / discharge the test sample in a state where the surrounding environment of the test sample is reproduced to simulate the actual use environment.

[0003] Japanese Patent Application Laid-Open No. 2007-292654

[0004] Incidentally, in electrical equipment such as an in-vehicle battery, heat is input to or released from the surrounding air, and heat is also input to or released from the power lines connected to the electrical equipment.

[0005] However, the test device of the above-mentioned Patent Document 1 can reproduce the temperature of the ambient environment using a humidity chamber and simulate heat input or heat dissipation through the ambient air, but cannot simulate heat input or heat dissipation through power lines connected to electrical equipment.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and its main objective is to test a test specimen while simulating the heat input or heat dissipation through an actual power line during actual use.

[0007] In other words, the specimen testing system of the present invention is a specimen testing system for testing a specimen which is an electrical device, and is characterized by comprising a test power line connected to the specimen, and a temperature adjustment device for adjusting the temperature of the test power line connected to the specimen.

[0008] In such a specimen testing system, the temperature of the test power lines connected to the specimen is adjusted using a temperature control device, so that the specimen can be tested while simulating the thermal environment during actual use of the specimen, specifically the heat input or heat dissipation through the actual power lines connected during actual use.

[0009] Specifically, it is desirable that the temperature adjustment device adjusts the temperature of the test power line so as to simulate the heat input or heat dissipation through the actual power line connected to the test specimen when the test specimen is actually used.

[0010] Furthermore, it is desirable that the temperature adjustment device adjusts the temperature of the test power line so as to simulate the temperature of the actual power line connected to the test specimen when the specimen is in actual use. Here, the temperature of the actual power line connected to the test specimen when in actual use may be determined by simulation, may be obtained from a past test such as a road test or a bench test, or may be obtained from a test such as a road test or a bench test that is conducted in real time.

[0011] The heat generation amount or temperature of the equipment connected via the actual power line during actual use is an important parameter in simulating heat input or heat dissipation via the actual power line. Therefore, the temperature adjustment device preferably includes a temperature regulator that adjusts the temperature of the test power line, a target temperature calculation unit that calculates a target temperature of the test power line using the heat generation amount or temperature of the equipment connected via the actual power line during actual use of the test specimen, and a control unit that controls the temperature regulator based on the target temperature obtained by the target temperature calculation unit.

[0012] Furthermore, when simulating heat input or heat dissipation through a real power line, important parameters include the heat generation amount of the test specimen during testing, the thermal characteristics of the test power line, the thermal characteristics of the real power line connected to the test specimen during actual use, and the thermal characteristics of the equipment connected to the test specimen via the real power line during actual use. Therefore, it is desirable that the target temperature calculation unit calculates the target temperature of the test power line using not only the heat generation amount or temperature of the equipment connected to the test specimen via the real power line during actual use, but also the heat generation amount of the test specimen during testing, the thermal characteristics of the test power line, the thermal characteristics of the real power line connected to the test specimen during actual use, and / or thermal characteristics other than the heat generation amount and temperature of the equipment connected to the test specimen via the real power line during actual use. This configuration makes it possible to simulate heat input or heat dissipation through a real power line under conditions that are closer to those during actual use.

[0013] Here, the heat generation amount or temperature of the equipment connected via the actual power line when the test specimen is actually used may be determined by simulation, or may be obtained from a past road test or bench test, or may be obtained from a test such as a road test or bench test that is conducted in real time.

[0014] The test specimen is preferably mounted on a vehicle, and the actual use of the test specimen is preferably when the vehicle is running, stopped, or charging. With this configuration, the test specimen can be tested while simulating heat input or heat dissipation through an actual power line while the vehicle is running.

[0015] In order to simulate the ambient temperature environment of the test specimen, it is desirable to further provide a thermostatic chamber to house the test specimen. With this configuration, the test specimen can be tested while simulating not only heat input or heat dissipation through the actual power lines connected to the test specimen, but also heat input or heat dissipation between the test specimen and the air surrounding the test specimen.

[0016] A specific example of the specimen is a battery. In this case, the specimen testing system may further include a charge / discharge device that charges and discharges the battery, and the test power line may connect the battery and the charge / discharge device.

[0017] Specific examples of the specimen include an inverter, an inverter-integrated motor in which an inverter and a motor are integrated, or an electric axle (eAxle) in which an inverter, a motor, and a transmission are integrated. In this case, the specimen testing system may further include a power supply device that supplies power to the inverter, and the test power line may connect the inverter and the power supply device.

[0018] Specific examples of the test subject include both a battery and an inverter, an inverter-integrated motor, or an electric axle. In this case, the test power line may connect the battery and the inverter. With this configuration, it is possible to test both the battery and the inverter simultaneously while transmitting and receiving power between the battery and the inverter.

[0019] Furthermore, if the test subject is both a battery and an inverter, an inverter-integrated motor, or an electric axle, the test subject testing system may further include a charging / discharging device that charges and discharges the battery and a power supply device that supplies power to the inverter. The test power line includes a first test power line connecting the battery and the charging / discharging device and a second test power line connecting the inverter and the power supply device. The temperature adjustment device includes a first temperature adjustment device that adjusts the temperature of the first test power line and a second temperature adjustment device that adjusts the temperature of the second test power line. In this configuration, the charging / discharging device and the power supply device are configured to be able to communicate with each other, and it is desirable that the charging / discharging device reproduces the behavior of the inverter, and the power supply device reproduces the behavior of the battery. With this configuration, both the battery and the inverter can be tested simultaneously even if the test room for testing the battery and the test room for testing the inverter are separate. Furthermore, since the first test power line and the second test power line can be shortened, the power loss in these test power lines can be reduced.

[0020] In addition, the temperature adjustment device of the present invention is a temperature adjustment device used for testing a specimen which is an electrical device, and is characterized by comprising a temperature regulator that adjusts the temperature of a test power line connected to the specimen, and a control unit that controls the temperature regulator so as to simulate heat input or heat dissipation via an actual power line connected to the specimen when the specimen is actually used.

[0021] Furthermore, the test specimen testing method according to the present invention is a test specimen testing method for testing a test specimen that is an electrical device, characterized in that a test power line is connected to the test specimen, the temperature of the test power line is adjusted, and the test specimen is tested.

[0022] Furthermore, the test specimen testing program of the present invention is a program used in a test specimen testing system having a test power line connected to a test specimen which is an electrical device and a temperature regulator that adjusts the temperature of the test power line, and is characterized in that it provides a computer with the function of a control unit that controls the temperature regulator so as to simulate heat input or heat dissipation through the actual power line connected to the test specimen when the specimen is actually used.

[0023] According to the present invention as described above, it is possible to test a test specimen while simulating heat input or heat dissipation via an actual power line during actual use.

[0025] <One embodiment of the present invention> Hereinafter, one embodiment of a specimen testing system according to the present invention will be described with reference to the drawings. Note that in all of the drawings shown below, parts are appropriately omitted or exaggerated for clarity. Identical components are assigned the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0026] 1. Configuration of the Specimen Testing System The specimen testing system 100 of this embodiment tests a specimen W, which is an electrical device. The specimen W, which is an electrical device, includes any one of a battery, an inverter, an electric motor, an inverter-integrated motor in which an inverter and a motor are integrated, or an electric axle (eAxle) in which an inverter, a motor, and a transmission are integrated. In the following, a battery mounted on a vehicle (including, for example, a four-wheeled automobile, a two-wheeled automobile, or a railway vehicle) will be described as an example of the specimen W. The battery may be a lithium-ion battery, a lead-acid battery, a fuel cell, or an all-solid-state battery.

[0027] Specifically, the specimen testing system 100 includes a thermostatic chamber 2 that houses the specimen W, a charge / discharge device 3 that charges / discharges the battery that is the specimen W, a test power line 4 that is connected to the specimen W and the charge / discharge device 3, and a temperature adjustment device 5 that adjusts the temperature of the test power line 4 that is connected to the specimen W. Note that the specimen testing system 100 may not have the thermostatic chamber 2.

[0028] The thermostatic chamber 2 simulates the ambient temperature environment (sealing, heat dissipation by airflow, etc.) of the battery under test W. If the battery under test W is water-cooled or liquid-cooled, a liquid circulation type battery temperature control device may be used to control the temperature of the battery. The battery temperature control device may also simulate the behavior of a circulation type temperature control system in an actual vehicle.

[0029] Specifically, the thermostatic chamber 2 has a storage space for storing the specimen W, and is configured so that the storage space can be kept at a predetermined temperature. The thermostatic chamber 2 is made of, for example, resin or a metal such as aluminum. Note that a heat insulating member may be provided on the inner surface of the thermostatic chamber 2.

[0030] The charge / discharge device 3 charges and discharges the battery, which is the test specimen W, so as to simulate the operation of an inverter or an electric motor connected to the test specimen W.

[0031] The test power line 4 has a connection terminal at one end to be connected to an external terminal of the test piece W, and a connection terminal at the other end to be connected to an external terminal of the charging / discharging device 3. This test power line 4 is an insulated electric wire in which the conductor is covered with an insulator, but it may also be a bare electric wire in which the conductor is not covered with an insulator. Furthermore, the thickness of the insulator may be reduced only in the portion to be temperature-controlled by the temperature control device 5 described below, or only the portion to be temperature-controlled by the temperature control device 5 may not be covered with an insulator.

[0032] The temperature adjustment device 5 adjusts the temperature of the test power line 4 so that it is equivalent to the temperature during actual use of the specimen W. Here, actual use of the specimen W refers to the time when the device on which the specimen W is mounted is operating. The device on which the specimen W is mounted may be a vehicle or something other than a vehicle. If the device on which the specimen W is mounted is a vehicle, actual use of the specimen W includes the time when the vehicle is running (including when running, idling, stopped, or starting up), when the vehicle is stopped other than when running, or when charging. This temperature adjustment device 5 adjusts the temperature of the test power line 4 so as to simulate heat input or heat dissipation through the actual power line connected to the specimen W during actual use of the specimen W. The actual power line is a power line that is included in the vehicle on which the specimen W is mounted and is connected to the specimen W.

[0033] Specifically, the temperature adjustment device 5 includes a temperature regulator 51 that adjusts the temperature of the test power line 4, a target temperature calculation unit 52 that calculates a target temperature of the test power line 4, and a control unit 53 that controls the temperature regulator 51 based on the target temperature obtained by the target temperature calculation unit 52. An electronic temperature regulator can be used as the temperature adjustment device 5. The target temperature calculation unit 52 and the control unit 53 are configured using a computer equipped with a CPU, memory, input / output interface, etc., and their functions are fulfilled by the CPU and peripheral devices working together in accordance with a test program stored in the memory.

[0034] The temperature regulator 51 has a heater and / or a cooler provided around the test power line 4. The heater may be, for example, a heating resistor or a heat transfer pipe. The cooler may be, for example, an electronic cooling element such as a Peltier element or a heat transfer pipe. The temperature regulator 51 may be provided on the entire test power line 4 or on a portion of it. When the temperature regulator 51 is provided on a portion of the test power line 4, it is desirable to provide it on the side of the test specimen W (for example, near the connection terminal to the test specimen W). The temperature regulator 51 may also be incorporated inside the test power line 4.

[0035] The target temperature calculation unit 52 calculates the target temperature of the test power line using the heat generation amount or temperature of the equipment connected via the actual power line during actual use of the specimen W. Furthermore, the target temperature calculation unit 52 calculates the target temperature of the test power line 4 using the heat generation amount of the specimen W during testing, the thermal characteristics of the test power line 4, the thermal characteristics of the actual power line connected during actual use of the specimen W, and / or thermal characteristics other than the heat generation amount of the equipment connected via the actual power line during actual use of the specimen W, in addition to the heat generation amount or temperature of the equipment connected via the actual power line during actual use of the specimen W.

[0036] Specifically, the target temperature calculation unit 52 calculates the target temperature of the test power line 4 based on parameters of the test specimen W, parameters of the actual vehicle in which the test specimen W is installed, and / or parameters of the test power line 4.

[0037] The parameters of the specimen W used to calculate the target temperature are at least one of the following (a) and (b): (a) the amount of heat generated by the specimen W during testing (for example, heat generated by current flow), (b) the ambient temperature of the specimen W (internal temperature of the thermostatic chamber), etc.

[0038] The parameters of the actual vehicle used to calculate the target temperature are at least one of the following (a) and (b): (a) thermal characteristics such as heat capacity, heat generation amount, thermal conductivity and / or heat dissipation characteristics of the actual power lines connected to the test piece W in the actual vehicle, (b) thermal characteristics such as heat capacity, heat generation amount, thermal conductivity and / or heat dissipation characteristics of the inverter and / or electric motor connected to the test piece W via the actual power lines in the actual vehicle, etc.

[0039] The parameters of the test power line 4 used to calculate the target temperature include thermal characteristics of the test power line 4, such as heat capacity, heat generation amount, thermal conductivity and / or heat dissipation characteristics.

[0040] Specifically, the target temperature calculation unit 52, for example, simulates a model equivalent to an actual vehicle to calculate an estimate of the temperature of the actual power lines in the actual vehicle. Then, using the estimate of the temperature of the actual power lines and the above-mentioned parameters, the target temperature calculation unit 52 calculates the target temperature of the test power lines 4, taking into account the difference between the model equivalent to the actual vehicle used in the simulation and the experimental model of the specimen test system.

[0041] The target temperature calculation unit 52 may calculate the target temperature of the test power line 4 using measured values ​​of the temperature of the actual power line in an actual vehicle obtained through a past test, such as a road test or a bench test. In this case, the target temperature calculation unit 52 may calculate the target temperature of the test power line 4 using the measured values ​​of the temperature of the actual power line and the above-mentioned parameters, taking into account the difference between the actual vehicle model used in the test and the experimental model of the test system under test. Alternatively, the target temperature calculation unit 52 may calculate the target temperature of the test power line 4 using only the above-mentioned parameters, without using estimated or measured values ​​of the temperature of the actual power line.

[0042] Furthermore, the target temperature calculation unit 52 may calculate the target temperature of the test power line 4 using measured values ​​of the temperature of the actual power line in an actual vehicle obtained from a road test or bench test being performed in real time, or from a past road test or bench test, etc. In this case, the target temperature calculation unit 52 may calculate the target temperature of the test power line 4 using the measured values ​​of the temperature of the actual power line and the above-mentioned parameters, taking into account the difference between the actual vehicle model used in the test and the experimental model of the specimen test system.

[0043] The control unit 53 controls the temperature regulator 51 based on the target temperature obtained by the target temperature calculation unit 52, thereby simulating the heat input or heat dissipation through the actual power line when the test specimen W is actually used (in this case, when the vehicle is running).

[0044] The target temperature calculation unit 52 and the control unit 53 may be provided in a control device (not shown) that controls the constant temperature bath 2 or the charge / discharge device 3 or the like.

[0045] 2. Temperature Adjustment Method of Test Power Line 4 Next, a temperature adjustment method of the test power line 4 will be described.

[0046] (Temperature Adjustment Method 1) First, the temperature of the actual power line during actual use of the specimen W is determined by simulation, or by actually measuring the temperature of the actual power line during actual use of the specimen W. Next, the determined temperature of the actual power line is corrected using at least one of the parameters described above to calculate a target temperature of the test power line 4. Then, based on the calculated target temperature, the temperature adjustment device 5 is controlled to adjust the temperature of the test power line 4.

[0047] (Temperature Adjustment Method 2) First, the temperature of the actual power line during actual use of the specimen W is determined by simulation, or by actually measuring the temperature of the actual power line during actual use of the specimen W. Then, the determined temperature of the actual power line is set as the target temperature of the test power line 4, and the temperature adjustment device 5 is controlled based on the target temperature to adjust the temperature of the test power line 4.

[0048] (Temperature Adjustment Method 3) At least one of the above parameters is used to calculate a target temperature for the test power line 4. Then, based on the calculated target temperature, the temperature adjustment device 5 is controlled to adjust the temperature of the test power line 4.

[0049] 3. Specimen Testing Method Next, a method for testing the specimen W using the specimen testing system 100 of this embodiment will be described with reference to FIG.

[0050] First, a test specimen W is placed inside the thermostatic chamber 2. The test specimen W placed in the thermostatic chamber 2 is connected to the charge / discharge device 3 via the test power line 4. Then, the thermostatic chamber 2 is used to simulate the ambient temperature environment during actual use of the test specimen W (step S1).

[0051] Next, the charging / discharging device 3 charges and discharges the test specimen W (battery) so as to simulate the operation of an inverter or electric motor connected to the test specimen W when the test specimen W is actually used (step S2).

[0052] Next, the target temperature calculation unit 52 calculates the target temperature of the test power line 4 using the heat generation amount or temperature of the equipment connected via the actual power line when the test specimen W is actually used, as well as the heat generation amount of the test specimen W during testing, the thermal characteristics of the test power line 4, the thermal characteristics of the actual power line connected to the test specimen W during actual use, and / or thermal characteristics other than the heat generation amount of the equipment connected via the actual power line when the test specimen W is actually used (step S3). Note that the order of steps S2 and S3 above may be reversed.

[0053] Finally, the control unit 53 controls the temperature regulator 51 based on the target temperature obtained by the target temperature calculation unit 52 .

[0054] <4. Effects of this embodiment> According to the specimen testing system 100 of this embodiment configured as described above, the temperature of the test power line 4 connected to the specimen W is adjusted by the temperature adjustment device 5, so that the specimen W can be tested while simulating the thermal environment during actual use, specifically, the heat input or heat dissipation via the actual power line connected during actual use.

[0055] 5. Other Embodiments For example, the specimen W in the above embodiment was a battery. However, as shown in FIG. 3 , the specimen W may be an inverter, an electric motor, an inverter-integrated motor in which the inverter and motor are integrated, or an electric axle (eAxle) in which the inverter, motor, and transmission are integrated. These specimens W can also be tested using a flow similar to that of the flowchart in FIG. 2 in the above embodiment. Note that FIG. 3 illustrates a case in which both an inverter and an electric motor are used as the specimen W. In this case, the specimen testing system 100 further includes a power supply device 7 that supplies power to the inverter, and the test power line 4 is configured to connect the inverter and the power supply device 7. The power supply device 7 supplies power to the inverter to simulate the behavior of a battery. A dynamometer 8 is also connected to the electric motor. Similarly to the above embodiment, the temperature adjustment device 5 that adjusts the temperature of the test power line 4 adjusts the temperature of the test power line 4 to simulate heat input or heat dissipation through the actual power line during actual use of the specimen W.

[0056] Furthermore, as shown in FIG. 4 , both a battery and an inverter may be used as the test specimen W. In FIG. 4 , in addition to the battery and inverter, an electric motor is also used as the test specimen. In this case, the test power line 4 is configured to connect the battery as the test specimen W and the inverter as the test specimen W. The temperature adjustment device 5 adjusts the temperature of the test power line 4 so as to simulate heat input or heat dissipation through the actual test power line. With this configuration, it is possible to simultaneously test both the battery and the inverter (electric motor) while transmitting and receiving power between the battery as the test specimen W and the inverter as the test specimen W.

[0057] In Figure 4, two temperature adjustment devices 5 are provided, one on the battery side, which is the test specimen W, and the other on the inverter side, which is the test specimen W. By providing a temperature adjustment device 5 on the battery side and the inverter side in this way, even if the test chamber (test chamber 1) where the battery is tested and the test chamber (test chamber 2) where the inverter is tested are separate, it is possible to simulate the heat input and heat dissipation to and from the battery and the inverter via actual power lines, respectively. As a result, it is possible to simultaneously test both the battery and the inverter under conditions that are closer to those of actual use.

[0058] Furthermore, when both the battery and the inverter are the DUT W, as shown in FIG. 5 , the DUT testing system 100 may further include a charging / discharging device 3 that charges and discharges the battery, and a power supply device 7 that supplies power to the inverter. The test power line 4 is configured to include a first test power line 4A that connects the battery and the charging / discharging device 3, and a second test power line 4B that connects the inverter and the power supply device 7. The temperature adjustment device 5 is configured to include a first temperature adjustment device 5A that adjusts the temperature of the first test power line 4A, and a second temperature adjustment device 5B that adjusts the temperature of the second test power line 4B. The test power lines 4A, 4B have the same configuration as in the above embodiment. The temperature adjustment devices 5A, 5B also have the same configuration as in the above embodiment.

[0059] In this configuration, the charging / discharging device 3 and the power supply device 7 are configured to be able to communicate with each other. This configuration includes a configuration in which a control device (not shown) that controls the charging / discharging device 3 and a control device (not shown) that controls the power supply device 7 are able to communicate with each other. The charging / discharging device 3 reproduces the behavior of the inverter under test, and the power supply device 7 reproduces the behavior of the battery. Specifically, the charging / discharging device 3 transmits battery charge / discharge information to the power supply device 7, and the power supply device 7, upon receiving the charge / discharge information, supplies power to the inverter based on the charge / discharge information. The power supply device 7 also transmits inverter operation information to the charging / discharging device 3, and the charging / discharging device 3, upon receiving the operation information, charges / discharges the battery based on the operation information. With this configuration, even if the test room (test room 1) where the battery is tested and the test room (test room 2) where the inverter is tested are separate, both the battery and the inverter can be tested simultaneously. Furthermore, since the first test power line 4A and the second test power line 4B can be shortened, the power loss in these test power lines 4A, 4B can be reduced.

[0060] Additionally, the temperature adjustment device 5 may adjust the temperature of the test power line 4 so that it is the temperature of the actual power line connected to the specimen W when the specimen W is in actual use. In this case, the target temperature of the test power line 4 is the temperature of the actual power line when the specimen W is in actual use. The temperature of the actual power line when in actual use may be determined by simulation, may be obtained from a past test such as a road test or a bench test, or may be obtained from a test such as a road test or a bench test that is performed in real time.

[0061] The target temperature of the test power line 4 may be the temperature of the actual power line that changes over time (for example, the temperature of the actual power line from the start of the test to the end of the test), or it may be the temperature of the actual power line at a certain time (for example, the temperature of the actual power line at the time when the temperature of the actual power line is highest).

[0062] Although the battery under test in the above embodiment is mounted on a vehicle, it may also be mounted on a mobile body other than a vehicle or a stationary power storage device. In this case, the actual power line is a power line that is provided on the mobile body other than a vehicle or the stationary power storage device and is connected to the test specimen W. Examples of mobile bodies other than vehicles include aircraft, drones, and ships, and examples of stationary power storage devices include factory / plant power storage devices and home power storage devices. In the present invention, the actual use of the test specimen W may refer to charging and / or discharging of the test specimen in a device (such as a vehicle, a mobile body other than a vehicle, or a stationary power storage device) in which the test specimen is mounted.

[0063] Furthermore, the specimen testing system 100 may be configured without the thermostatic chamber 2, or may be configured with a reproduction device that reproduces the environment during actual vehicle running.

[0064] The specimen may be an in-vehicle electrical device other than a battery, an inverter, or an electric motor, or may be an electrical device other than an in-vehicle electrical device.

[0065] The test performed by the specimen testing system of the present invention may be a heat generation test of a battery. This heat generation test of a battery may be, for example, a safety evaluation test to check for abnormal heat generation or a performance evaluation test to check the heat dissipation characteristics of the battery. It may also be a driving mode test that takes into account the driving mode of the vehicle in which the battery is installed.

[0066] The test performed by the specimen testing system of the present invention may also be a test of the degree of deterioration of a battery. This test of the degree of deterioration of a battery may be, for example, an evaluation test on the degree of deterioration of a reused battery or a battery under development. Furthermore, the test performed by the specimen testing system of the present invention may also be an evaluation test of a battery pack or a battery case. This evaluation test of a battery pack or a battery case may be, for example, an evaluation test of the thermal characteristics of the battery pack, or an evaluation test of the cooling performance or thermal characteristics of the battery case.

[0067] In addition, various modifications and combinations of the embodiments may be made as long as they do not go against the spirit of the present invention.
