[0016] Patent Document 6: Japanese Patent No. 6055806 Summary of the invention

[0017] However, the charge and discharge power supply device described in Patent Document 1 is a structure using a highly integrated converter assembly composed of highly integrated converters, but has no cooling function. Therefore, when the charge and discharge current increases, the heat generation of the device may increase during use.

[0018] In addition, the secondary battery charging and discharging device described in Patent Document 2 and the charging and discharging inspection system described in Patent Document 3 are difficult to use due to the number of types of wiring and the complexity of the mechanism (Patent Document 2). Figure 1 , Figure 2 , Patent Document 3 Figure 1etc.), which may become the main cause of cost increase or be difficult to maintain.

[0019] In addition, the inventions described in Patent Documents 4 to 6 are also required to have devices that can cope with the above-mentioned problems.

[0020] Therefore, an object of the present invention is to provide a charge and discharge inspection device and a charge and discharge inspection apparatus that can realize more effective charge and discharge inspection even with the increase of charge and discharge current and the advancement of high functionality of charge and discharge inspection devices.

[0021] The charge and discharge inspection device of the present invention comprises: a probe unit having a base substrate; a plurality of power supply substrates inserted into the base substrate and used integrally with the probe unit; and a plurality of probes electrically connected to the power supply substrate and arranged on the probe unit, wherein the power supply substrate has a control unit for performing control for charge and discharge inspection, and the base substrate has a cooling unit for cooling the power supply substrate.

[0022] Thus, the base substrate and the power substrate are used integrally with the probe unit, and the control unit supplies power from the power substrate to the probe to perform the charge and discharge inspection, and the cooling unit suppresses heat generation of the power substrate.

[0023] Particularly preferably, the base substrate and the power substrate are separate bodies, and the type of the base substrate and / or the number of the power substrates are selected according to the type and / or the number of the secondary batteries to be inspected, and are used integrally with the probe unit.

[0024] Thus, the type of base substrate and the number of power supply substrates to be inserted can be changed according to the type and capacity of the secondary battery to be inspected.

[0025] Furthermore, the charge and discharge inspection device preferably includes an elastic portion provided in the probe unit, respectively provided between the probe unit and the positive electrode and the negative electrode of the plurality of probes, and deformed relative to the probe unit in response to a force in a direction in which the secondary battery is mounted.

[0026] Thus, the force generated when the electrode of the secondary battery comes into contact with the electrode of the probe of the probe unit is received by the probe unit via the elastic portion.

[0027] Furthermore, preferably, the power board includes first voltage monitoring means for monitoring the voltage of the secondary battery to be inspected, and the base board includes second voltage monitoring means for monitoring the voltage of the secondary battery and power supply stopping means for stopping the operation of the power board.

[0028] Thus, the abnormality of the voltage of the secondary battery can be monitored by the first voltage monitoring unit on the power substrate side, and the abnormality of the voltage of the secondary battery can be further monitored by the second voltage monitoring unit on the base substrate side. Moreover, even if an abnormality is detected in the voltage of the secondary battery, the operation of the power substrate can be stopped by the power stop unit.

[0029] Furthermore, the charge and discharge inspection device preferably includes: a terminal block provided with probes and slidable in the arrangement direction of the probes; and a wiring which is flexible and provided in the probe unit and electrically connects the power substrate and the terminal block.

[0030] Thus, the probes can freely slide and move in the arrangement direction thereof, that is, in the direction of approaching or moving away from each other.

[0031] On the other hand, the charge and discharge inspection equipment comprises: these charge and discharge inspection devices; and a diagnostic device that can accommodate the charge and discharge inspection devices and has a diagnostic unit that diagnoses the presence or absence of dirt or wear on the charge and discharge inspection devices, or the normality of one or more of a power supply substrate, a cooling unit, a first voltage monitoring unit, a second voltage monitoring unit, and a power supply stop unit.

[0032] Furthermore, preferably, the charge and discharge inspection device includes a maintenance device that can accommodate the charge and discharge inspection device and has a maintenance unit that removes dirt from the charge and discharge inspection device, replaces worn parts, or performs one or more of calibrations of the power substrate, the cooling unit, the first voltage monitoring unit, the second voltage monitoring unit, and the power supply stop unit. With such a charge and discharge inspection device, the charge and discharge inspection device can be diagnosed by the diagnostic device or maintained by the maintenance device.

[0033] (1) The charge and discharge inspection device of the present invention comprises: a probe unit having a base substrate; a plurality of power supply substrates inserted into the base substrate and used integrally with the probe unit; and a plurality of probes electrically connected to the power supply substrate and arranged in the probe unit, wherein the power supply substrate has a control unit for performing control for charge and discharge inspection, and the base substrate has a cooling unit for cooling the power supply substrate. Through the above structure, the base substrate and the power supply substrate are used integrally with the probe unit, and the charge and discharge inspection is performed by supplying power from the power supply substrate to the probes through the control unit, and the heat generation of the power supply substrate is suppressed by the cooling unit, so that even when the charge and discharge current increases, the risk of malfunction, obstacle occurrence, etc. for the charge and discharge inspection can be reduced.

[0034] (2) In particular, the base substrate and the power substrate are separate bodies, and the type of the base substrate and / or the number of the power substrates are selected according to the type and / or the number of the secondary batteries to be inspected, and are used integrally with the probe unit. Through the above structure, the type of the base substrate and the number of the inserted power substrates can be changed according to the type and capacity of the secondary batteries to be inspected, thereby realizing a highly expandable equipment design corresponding to the specifications in the equipment.

[0035] (3) In addition, the charge and discharge inspection device has an elastic portion, which is arranged in the probe unit and is respectively arranged between the probe unit and the positive electrode and the negative electrode of the plurality of probes. The elastic portion is deformed relative to the probe unit in response to the force in the direction in which the secondary battery is installed. Through the above structure, the force generated when the electrode of the secondary battery contacts the electrode of the probe of the probe unit is received by the probe unit through the elastic portion, so that the power supply substrate and the like will not be subjected to the force from the outside, thereby being able to suppress the risk of failure and malfunction.

[0036] (4) In addition, the power substrate has a first voltage monitoring unit that monitors the voltage of the secondary battery to be inspected, and the base substrate has a second voltage monitoring unit that monitors the voltage of the secondary battery and a power stop unit that stops the operation of the power substrate. With the above structure, the abnormality of the voltage of the secondary battery can be monitored on the power substrate side by the first voltage monitoring unit, and the abnormality of the voltage of the secondary battery can be further monitored on the base substrate side by the second voltage monitoring unit. Moreover, even if an abnormality is detected in the voltage of the secondary battery, the operation of the power substrate can be stopped by the power stop unit. Therefore, even if an abnormality is detected, there is no need for intervention of an external (higher) system such as a personal computer or a controller, and the connection wiring to the outside can be simplified (omitted).

[0037] (5) In addition, the charge and discharge inspection device comprises: a terminal block provided with probes which can slide in the arrangement direction of the probes; and wiring which is flexible wiring provided in the probe unit and electrically connects the power supply substrate and the terminal block. Through the above structure, the probes can slide freely along the arrangement direction thereof, that is, in the direction of approaching or moving away from each other, thereby preventing the secondary batteries from expanding and contacting each other during the charge and discharge inspection.

[0038] (6) Furthermore, according to the above-mentioned charge and discharge inspection equipment, the charge and discharge inspection device can be diagnosed by the diagnosis device or maintained by the maintenance device, so that the efficiency of the charge and discharge inspection can be further improved.

[0044] Hereinafter, an embodiment of the present invention will be described in detail. However, the description of the constituent elements described below is an example (representative example) of the embodiment of the present invention, and the present invention is not limited to the following contents unless the gist of the invention is changed.

[0045] [Charge and discharge inspection device]

[0046] Figure 1 1 is a schematic diagram showing a charge and discharge inspection device according to an embodiment of the present invention. The charge and discharge inspection device 1 comprises: a probe unit 10 having a base substrate 11; a plurality of power substrates D inserted into the base substrate 11 and used integrally with the probe unit 10; and a plurality of probes P electrically connected to the power substrate D and provided on the probe unit 10.

[0047] The power substrate D can be inserted into the base substrate 11 and can be attached and detached from the base substrate 11. Therefore, the number of inserted power substrates D can be increased or decreased in accordance with the capacity of the secondary battery B to be inspected. In the present embodiment, four power substrates D (power substrates D1 to D4) are inserted into the base substrate 11. In addition, the power substrate D is supplied with power from an AC / DC power supply connected to the probe unit 10.

[0048] It is particularly preferred that the base substrate 11 and the power substrate D are separate bodies. Thus, the number of power substrates D can be selected according to the type and / or number of the secondary batteries B to be inspected. For example, by preparing a plurality of power substrates D, the current value can be increased. That is, the current value that can be supplied during the charge and discharge inspection can be adjusted (increased or decreased) according to the type and number of the secondary batteries B to be inspected.

[0049] Furthermore, the type of base substrate 11 can be selected according to the type and / or number of the secondary batteries B to be inspected. For example, the most appropriate base substrate can be selected from base substrates that can accommodate (insert) different numbers of power substrates D in accordance with the specifications of the device.

[0050] In addition, it is also possible to test a secondary battery B using multiple power supply substrates D. Specifically, multiple power supply substrates D (for example, two) can be virtually regarded as one power supply for testing. In addition, by physically combining a control unit D111 (see Figure 3 ) and a plurality of power supply substrates D (for example, two), a power supply can be formed and tested.

[0051] As described above, the base substrate 11 and the power substrate D are separate bodies, thereby enabling a device design with high expandability.

[0052] In addition, the probe P contacts the electrode of the secondary battery B and supplies power to the secondary battery B. In the present embodiment, there are four secondary batteries B (secondary batteries B1 to B4), so the probe P is also provided in four (probes P1 to P4) probe units 10. These probes may be not only needle-shaped but also clip-shaped or probes matching the electrodes of the secondary batteries of the inspection device may be used as appropriate.

[0053] The probe P is connected to the power board D via the cable C. For example, the probe P1 is connected to the power board D1 via the cable C1, and the power from the power board D1 is supplied to the secondary battery B1 via the cable C1 and the probe P1. The same is true for the probes P2 to P4.

[0054] Furthermore, the probe unit 10 includes a temperature probe T for measuring the temperature of the secondary battery B. In the present embodiment, temperature probes T1 to T4 are provided near the probes P1 to P4, respectively.

[0055] Figure 2 1 is another schematic diagram showing the structure of the charge and discharge inspection device according to the embodiment of the present invention. Figure 1 The same structures as described above are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0056] like Figure 2 As shown, the probe P contacts the electrode (terminal) of the secondary battery B. For example, the secondary battery B Figure 2 The probe unit 10 is moved in the direction of the arrow shown and mounted on the probe unit 10. Of course, the probe unit 10 may be moved and mounted on the secondary battery B.

[0057] At this time, if the current becomes large (if the charge and discharge current increases), in order to reduce the contact resistance between the probe and the secondary battery, a high contact pressure is required between them. Therefore, when installing the secondary battery B, the power supply substrate D (see Figure 1 ) may be subjected to force.

[0058] Therefore, it is preferable to provide an elastic portion 12 such as a spring in the probe unit 10. Figure 2 As shown, the elastic parts 12 ( 121 to 124 ) are provided between the probe unit 10 and the positive electrode (not shown) and the negative electrode (not shown) of the probe P, respectively, and deform relative to the probe unit 10 in response to the force in the direction of mounting the secondary battery B.

[0059] That is, the force generated when the electrode of the secondary battery B1 contacts the electrode of the probe P1 of the probe unit 10 is received by the probe unit 10 through the elastic portion 121. Therefore, although the probe unit 10 is integrally provided with the power substrate D, other important substrates, circuits, and mechanisms for controlling high-level processing (such as the control unit D111 and the cooling unit 113 described later) through the base substrate 11, these power substrates D and the like are not subjected to external forces, and the risk of failure and malfunction can be suppressed.

[0060] [Base substrate]

[0061] Figure 3 This is a schematic functional block diagram of a base substrate of a charge and discharge inspection device according to an embodiment of the present invention. In this embodiment, the base substrate 11 has a power stop unit 111, a second voltage monitoring unit 112, and a cooling unit 113. On the other hand, the power substrate D has a control unit D111 and a first voltage monitoring unit D112.

[0062] In addition, the base substrate 11 is provided with a power line and a communication line. Therefore, using the power line, power from the inserted power substrate D can be transmitted to the probe P, or power can be supplied to the substrate that can realize these units. Furthermore, using the communication line, these units can communicate with each other.

[0063] The control unit D111 is a unit that communicates bidirectionally with an external personal computer via a controller, and controls the supply or stop of power from the power board D to the probe P for charge and discharge inspection according to instructions from the personal computer.

[0064] Furthermore, the cooling unit 113 is a unit for cooling the power supply substrate D inserted into the base substrate 11. The cooling unit 113 is, for example, a cooling fan.

[0065] The second voltage monitoring unit 112 monitors the voltage of the secondary battery B. On the other hand, the power source substrate D also includes the first voltage monitoring unit D112 that monitors the voltage of the secondary battery B as described above.

[0066] Therefore, for example, the control unit D111 collects the monitoring results of the first voltage monitoring unit D112 and the monitoring results of the second voltage monitoring unit 112, and when the monitoring results of either one are abnormal, the control unit D111 can notify the meaning. Notifying the meaning means, for example, displaying an image representing the meaning on a personal computer through communication, playing an emergency sound, or lighting a red light of a light-emitting unit (not shown), etc.

[0067] When an abnormality is detected in the voltage of the secondary battery B, the power supply stop unit 111 stops the operation of the power board D, that is, the supply of power to the secondary battery B.

[0068] For example, as an example of a specific structure of the power stop unit 111, Figure 3 As shown, a switch such as a relay is provided between the power line connecting the power supply substrate D and the probe P, and the switch is cut off when an abnormality is detected ( Figure 3 ), it is possible to stop the power supply to the secondary battery.

[0069] Thus, even when an abnormality is detected in the voltage of the secondary battery, there is no need for intervention of an external (superior) system such as a personal computer or a controller, and the connection wiring to the outside can be simplified (omitted). In addition, in the case where a switch such as a relay is not provided, for example, even if the control unit D111 detects an abnormality and stops the power supply of the power substrate D, the same effect can be achieved. In addition, by notifying the control unit D111 of the power substrate D of the abnormality information detected by the power stop unit 111, it is also possible to notify an external (superior) system such as a personal computer through the communication unit of the power substrate D.

[0070] In addition, the power supply substrate D includes a current wiring for supplying power and a voltage wiring for detecting voltage. Here, the first voltage monitoring unit D112 can obtain information from the voltage wiring. On the other hand, the second voltage monitoring unit 112 can also obtain information from any wiring.

[0071] Here, it is particularly preferable that the first voltage monitoring unit D112 detects the abnormal voltage of the secondary battery based on information obtained from the voltage wiring, and the second voltage monitoring unit 112 detects the abnormal voltage of the secondary battery based on information obtained from the current wiring. Thus, the abnormal voltage of the secondary battery can be detected more accurately.

[0072] For example, when poor contact occurs at a pin of a voltage wiring, in a structure in which either the first voltage monitoring unit D112 or the second voltage monitoring unit 112 detects a voltage abnormality of the secondary battery based on information obtained from the voltage wiring, the abnormality (poor contact) may not be detected.

[0073] Therefore, since the charge and discharge inspection device 1 can monitor the voltage of the secondary battery B in a dual manner, safety in the charge and discharge inspection can be ensured even if a large current flows (even if the charge and discharge current increases).

[0074] [Modification of Probe Unit]

[0075] Figure 4 FIG. 2 is a schematic diagram showing a charge and discharge inspection device according to another embodiment of the present invention. Figure 4 As shown, the probe unit 10 may have a structure including the terminal blocks 13 ( 131 to 134 ) and flexible wirings W ( W1 to W4 ).

[0076] The terminal block 13 is provided with a probe P which can be Figure 4 The terminal block 13 is connected to the power board D via the wiring W. That is, in this embodiment, the power from the power board D (D1 to D4) is transmitted to the probes P (P1 to P4) via the wiring W (W1 to W4) and the cables C (C1 to C4).

[0077] Here, the terminal block 13 can be Figure 4 The probe P provided on the terminal block 13 can also move in the direction of the arrow shown, that is, the arrangement direction of other terminal blocks (eg, can slide).

[0078] Thus, probes P1~P4 can move in a direction approaching or moving away from each other, so even if the secondary battery B expands during the charge and discharge inspection, or there is an error in the thickness and width of the secondary battery B, it is possible to prevent the secondary batteries B from contacting each other or the probe unit 10 from being unable to be installed on the secondary battery B.

[0079] Similarly, the temperature probe T may be connected via the wiring W from the terminal block 13 .

[0080] [Charge and discharge inspection equipment]

[0081] Figure 5 1 is a schematic diagram showing a charge and discharge inspection device according to an embodiment of the present invention. Figure 5 As shown, the charge and discharge inspection device 100 is as follows Figure 2As described in , a plurality of places are provided to accommodate the charge and discharge inspection device 1 , the AC / DC power source, and the secondary battery B to be inspected. In addition, a controller or a personal computer is connected to the charge and discharge inspection equipment 100 , and can communicate bidirectionally with any charge and discharge inspection device 1 .

[0082] Furthermore, the charge and discharge inspection equipment 100 includes a diagnostic device 20 capable of accommodating the charge and discharge inspection device 1. Furthermore, the diagnostic device 20 includes a diagnostic unit (not shown).

[0083] The diagnostic unit functions implement the functions shown below.

[0084] (1) Diagnosis of contamination of the contained charge and discharge inspection device. For example, detection of poor contact caused by dust adhesion.

[0085] (2) Diagnosis of wear of the contained charge and discharge inspection device. For example, detection of probes that have been worn and degraded.

[0086] (3) Diagnosis of the normality of the power supply board. For example, detection of accuracy deviation of voltage, current, and temperature.

[0087] (4) Diagnosis of the normality of the cooling unit. For example, detection of a cooling fan failure.

[0088] (5) Diagnosis of the normality of the first voltage monitoring unit and the second voltage monitoring unit. In other words, diagnosis of whether the dual monitoring function is operating normally.

[0089] (6) Diagnosis of the normality of the power supply stop unit.

[0090] Furthermore, the charge and discharge inspection equipment 100 includes a maintenance device 30 capable of accommodating the charge and discharge inspection device 1. Furthermore, the maintenance device 30 includes a maintenance unit (not shown).

[0091] The maintenance unit can perform the following functions.

[0092] (1) Removal of dirt from the contained charge and discharge inspection device.

[0093] (2) Replacement of worn parts of the stored charge and discharge inspection device. For example, this also includes replacement of a failed cooling fan.

[0094] (3) Calibration of the power supply board. For example, calibration of voltage, current, and temperature accuracy deviation.

[0095] (4) Calibration of the first voltage monitoring unit and the second voltage monitoring unit. For example, the accuracy (threshold) of determining that the voltage of the secondary battery is abnormal is corrected.

[0096] (5) Correction of the normality of the power supply stop unit.

[0097] By configuring the charge and discharge inspection device 100 as such, the charge and discharge inspection device 1 can be moved in the horizontal direction or raised and lowered in the vertical direction, for example, by a conveying device (a stacker crane is an example), so that the charge and discharge inspection device 1 can be easily diagnosed by the diagnostic device 20, and the device in which a problem is detected during the diagnosis can be immediately maintained by the maintenance device 30.

[0098] In addition, as described above, the charge and discharge inspection device 1 is an integrated device including a probe unit, a power source, etc. Therefore, since the charge and discharge inspection device 1 used in the charge and discharge inspection can be immediately diagnosed after being removed from the secondary battery B, or a faulty charge and discharge inspection device 1 can be immediately replaced with a normal device, the impact on the production cycle of the charge and discharge inspection can be minimized.

[0099] Furthermore, since the various functions described above can be realized by the base substrate 11 included in the probe unit 1 , it is possible to avoid problems such as the complication of the mechanism of the charge and discharge inspection device, the increase in cost, and the difficulty in maintenance.

[0100] The present embodiment described above is merely an example, and the configurations of the probe unit 10 , the charge and discharge inspection device 1 , and the charge and discharge inspection equipment 100 can be appropriately modified in design without departing from the gist of the present invention.
