Description

Technical Field

[0001] The invention relates to a data recording device for battery testing, which is specifically used for tracking, collecting and storing battery single-cell life charge and discharge test data. Background Art

[0002] With the rise of the new energy industry, batteries have been widely used in various industries as energy storage devices. However, the production levels of various battery manufacturers are uneven, the quality of batteries is generally low (low means lower than the declared parameters), and the battery life cannot reach the expected target. Therefore, it is an important task to strengthen the inspection of battery life.

[0003] The single-cell battery life charge and discharge test is the most effective battery life detection test. The test method is to connect the tested battery to a high-current charge and discharge tester, set standard test parameters on the charge and discharge tester, and perform long-term multi-cycle charge and discharge on the battery. The most important task during the test is to record the test data. The recorded data must be accurate without any mistakes. The data directly reflects the length of the battery life.

[0004] Existing charge and discharge testers do not have data recording function. The data recording method is one of two methods performed by the operator according to the actual on-site working conditions:

[0005] The first data recording method is manual recording, which involves manually recording the data on the display screen of the charge and discharge tester at regular intervals. This method requires a huge workload and excessively occupies the operator's working time, preventing them from being able to devote themselves to other operation and maintenance work.

[0006] In view of the shortcomings of the first data recording method, the operators designed a method to reduce workload and improve work efficiency, that is, to adopt the second data recording method. The second data recording method is to use a work recorder (also called an image recorder, which is the same type of product as the common driving recorders on the market) to record the screen of the charging and discharging instrument. After the test, the tester records the work recorder video data. The daily charging and discharging test lasts up to 10 hours, and each battery needs to undergo 30 charge and discharge cycles. The entire test time for a battery is 9 days, and there must be no interruptions, omissions, or gaps in the middle, and the work continuity is strong. There are many shortcomings in the work recorder data recording method, and these shortcomings have become increasingly prominent in the process of our test data recording;

[0007] If the following deficiencies can be resolved, our new products will have very high product reliability and quality, and at the same time be able to ensure that they have a wider and more reliable market adaptability:

[0008] 1. The work recorder records video for a long time, resulting in insufficient memory, and continuous recording generates a large amount of useless videos;

[0009] 2. The charge and discharge tester automatically turns off the screen at a fixed time. After the screen turns black, the work recorder cannot record the screen data. It is necessary to manually touch the screen of the charge and discharge instrument to continue recording. The automatic screen off of the charge and discharge test instrument cannot be controlled and must be manually touched, which has the greatest impact on the recording process. The work recorder is just a simple recording tool and cannot replace manual lighting of the screen. It has no intelligence and still requires manual squatting next to the instrument, which is very inconvenient. We have conducted sufficient research on the automatic screen off of the charge and discharge tester and designed to overcome this problem. Specifically:

[0010] 1) The screen-off time setting of the charge and discharge tester is a function that must be available before leaving the factory. As a manufacturer, there is no obligation or desire to change the screen-off time. At present, the manufacturer refuses to make changes to the automatic screen-off function.

[0011] 2) The program for changing the screen-off time of the charge and discharge tester needs to be modified by the manufacturer. Considering that the manufacturer is not obligated to complete the program change work, even if we change the screen-off time of a certain charge and discharge tester, all other instruments of different manufacturers and models must modify the program, which is prone to errors and wastes time. Therefore, it is very necessary to creatively design a solution that can be easily installed and can wake up the screen of the charge and discharge tester after the screen is turned off. Summary of the invention

[0012] The technical problem to be solved by the present invention is to provide a battery cell life charge and discharge test data tracking and acquisition instrument and acquisition method in view of the deficiencies in the above-mentioned prior art.

[0047] The data acquisition controller is connected to the image recorder 21 via the image recorder interface 19; the data acquisition controller is connected to the magnetic device (12, 25) via the magnetic device interface 20;

[0048] The data acquisition controller comprises an external main power supply 1 (the external main power supply is 220V AC) for supplying power to the entire data acquisition instrument.

The 12V power module I and the 12V power module II are respectively connected to a time cycle relay I (8) through a power supply circuit, and the time cycle relay I (8) is connected to the image recorder 21. The power supply circuit of the 12V power module I is also connected to a manual recording button 7, and the other end of the manual recording button 7 is electrically connected to the image recorder 21. The manual recording button 7 designed by the present invention can be manually controlled in the manual mode.

[0050] The magnetic attraction device (12, 25) is installed on the charge and discharge tester 24, and the magnetic attraction device includes an electromagnet 2503 and a touch panel 2507 that is attracted and released by the electromagnet. After the electromagnet 2503 attracts the touch panel 2507, the touch panel 2507 presses the control button of the charge and discharge tester 24 to wake up the screen of the charge and discharge tester 24 in the off state.

[0051] As a preferred embodiment of the collector of the present invention, Figure 4 , 5, 6: The magnetic suction device 25 also includes a connecting plate 2501 connected to the side of the charge and discharge tester 24, an extension plate 2504 is connected to the connecting plate 2501, the electromagnet 2503 is installed on the extension plate 2504, the distal end of the extension plate 2504 is installed with a vertical plate 2505 perpendicular to the extension plate 2504, the top of the vertical plate 2505 is connected to the touch panel 2507 through a hinge 2506, and the distal end of the touch panel 2507 presses the control button of the charge and discharge tester 24 closest to the electromagnet, and the control button closest to the electromagnet is the wake-up button 26. The magnetic suction device disclosed in this embodiment realizes the function of being conveniently installed on the side of the charge and discharge tester through the connecting plate, the electromagnet is fixed through the extension plate, the hinge and the touch panel are assembled through the vertical plate, and the swing and pressing of the touch panel during the magnetic suction process is realized through the hinge; the touch panel realizes the touch of the control button. The definition of the wake-up button in this embodiment makes the touch panel only designed to touch the wake-up button and not touch other buttons.

[0052] As a preferred embodiment of the collector of the present invention, Figure 1 , 2 , 3, and 4: The data acquisition controller includes a controller housing 13 of a box structure, the front of the controller housing 13 is a control panel, and the back of the controller housing is equipped with the jack of the external main power supply 1, the image recorder interface 19, and the magnetic suction device interface 20.

[0053] As a preferred embodiment of the collector of the present invention, Figure 4 As shown: the image recorder 21 includes a bracket assembly for adjusting the camera of the image recorder 21 to face the display screen 28 of the charge and discharge tester 24. The bracket assembly of the image recorder disclosed in this embodiment is conducive to long-term support of the image recorder and screen adjustment of the display screen of the charge and discharge tester.

[0054] As a preferred embodiment of the collector of the present invention, Figure 4 As shown: the support assembly includes a universal support 22, the top of the universal support 22 is connected to the image recorder (11, 21); the bottom of the universal support 22 is connected to a tripod support 23; the bottom surface of the image recorder (11, 21) is provided with an internal threaded hole for connecting the universal support. The structure disclosed in this embodiment adopts a tripod support to achieve height adjustment and stable support, and the angle adjustment of the image recorder is achieved through the universal support.

[0055] As a preferred embodiment of the collector of the present invention, as shown in the figure: the bracket assembly includes a clamp for clamping the image recorder (11, 21), the clamp is installed on the universal joint support, and the universal joint support is connected to a clamp for clamping on the back plate of the charge and discharge tester 24 through a bracket hose. The bracket assembly disclosed in this embodiment does not occupy the space in front of a separate charge and discharge tester, and can be directly clamped on the charge and discharge tester through the clamp, and then extended to the front of the display screen through the hose. After the image recorder is clamped by the clamp, the angle is further adjusted through the universal joint support. The structure of this embodiment is more flexible and compact, does not occupy external space, and prevents collision. In addition, the bracket assembly and the charge and discharge tester of this embodiment are relatively connected and fixed. As long as the charge and discharge tester moves, the bracket assembly moves synchronously without the need for re-adjustment.

[0056] The present invention also discloses a method for tracking and collecting battery monomer life charge and discharge test data, which uses any of the above-mentioned collectors to perform the following steps:

[0057] (1) Set the data tracking acquisition time to C minutes through the time control switch;

[0058] (2) Setting the cycle control time of the time cycle relay 1 to D minutes, and setting the photo taking time of the image recorder;

[0059] (3) Setting the cycle control time of the time cycle relay II to E minutes, and setting the start and stop time of the electromagnet of the magnetic attraction device;

[0060] (4) The image recorder takes a photo of the display screen of the charge and discharge tester every D minutes until the C-minute working time set in step (1) is completed or the tester is manually stopped;

[0061] (5) The magnetic device is activated every E minutes, and the touch panel presses the wake-up button of the charge and discharge tester once, until the C-minute working time set in step (1) is completed or it is manually stopped. The acquisition method disclosed in the present invention can realize fully automatic process control. After the initial setting, the operator only needs to check the final data. In this way, the entire battery cell life charge and discharge test process is assisted to be fully automatically and reliably completed, so that the operator can completely carry out the rest of the operation and maintenance work during the charge and discharge test process, and complete more work simultaneously, which greatly improves efficiency.

[0062] As a preferred embodiment of the collection method disclosed in the present invention, as shown in the figure: D=15; E is equal to the automatic screen-off time of the charge-discharge tester. In this embodiment, the battery charge-discharge durability test, according to this test requirement, the staff should record the charge and discharge data of a single test battery for 15 days, and perform 10 hours of charging and 10 hours of discharging once a day. If the 15-day data is recorded continuously, the amount is too large. After long-term test experience, we concluded that we use the work recorder to take pictures every 15 minutes, and finally record the photo data manually. This method saves the memory card space of the work recorder, and will not cause the data collection to be too low to affect the test conclusion. Taking pictures once every 15 minutes is the best. The collection method disclosed in this embodiment can realize the automatic power on and off of the collection instrument, and automatically record the screen of the charge-discharge instrument once every 15 minutes after turning it on; and the electromagnetic trigger device can automatically touch the panel button of the charge-discharge instrument instead of manually lighting the screen. The test personnel do not need to squat beside the instrument throughout the whole process, which greatly saves manpower.

[0063] As a preferred embodiment of the acquisition method disclosed in the present invention, as shown in the figure: the step of magnetic suction detection is also included between step (2) and step (3), firstly, the armature movable stroke in the electromagnetic trigger is changed by adjusting the screw in the electromagnetic trigger of the electromagnet, and an optimal armature movable stroke position is obtained after multiple adjustments, and then the magnetic suction device remembers the armature movable stroke position, so as to avoid the touch panel failing to hit the wake-up button or hitting the wake-up button too hard when the magnetic suction device is working, causing damage to the button. This embodiment is conducive to the adjustment memory storage of the optimal touch force of the touch panel by adding the step of magnetic suction detection, avoiding the defects of damage to the button or invalid touch.

[0064] In summary, the present invention can reduce the labor intensity of test personnel and provide accurate original test data. In the future, screen recording devices will be installed on the equipment of substations and various communication power supply rooms to transmit wirelessly to the background or mobile phone, so that the information value of the equipment during operation can be monitored and read in real time. We have contacted the manufacturer and are ready for production. This product can be used as an auxiliary product of the old activation instrument, which can further improve the function of the activation instrument and provide a reliable basis for the renovation of old products.

[0065] 1. Aiming at the shortcoming that the working recorder cannot record useful data regularly, the present invention designs a cycle time relay, so that the data recorder controller can set the time and start the working recorder every 15 minutes to record the charging and discharging instrument.

[0066] 2. In view of the shortcoming that the screen of the charging and discharging instrument will automatically turn off if no one touches it for a long time, the present invention designs an electromagnetic touch device. This device is installed on the charging and discharging instrument and is linked with the circulation relay. The electromagnetic device periodically attracts and touches the panel buttons on the charging and discharging instrument to ensure that the work recorder will not record a black screen.

[0067] 3. The present invention also improves the electromagnetic trigger device. If the electromagnetic trigger device has insufficient stroke, the button will not be triggered. If the stroke is too long, it will damage the instrument button. Therefore, a magnetic detector is designed to detect the normal trigger stroke range of the electromagnetic trigger device, and it has a memory function. The magnetic detector is a small component installed in the largest device box of the data recorder. The actual picture will be provided later. Its working principle is that the staff first adjusts the screws in the electromagnetic trigger to change the armature movable stroke in the electromagnetic trigger. After multiple adjustments, an optimal armature movable stroke position is obtained, and then the magnetic detector remembers the armature movable stroke position, so as to avoid the armature failing to hit the screen button or hitting the button too hard when the electromagnetic trigger is working, causing damage to the button.

[0068] 4. The present invention improves the ordinary work recorder. The battery single life charge and discharge test data tracking and acquisition instrument component has a simple structure, is easy to assemble, has a low production cost, is light in weight, and is compact in size. It is suitable for continuous and periodic test data recording, tracking, and acquisition work, and has the characteristics of reasonable design, easy modification, and low modification cost.

[0069] In addition, it should be noted that the data acquisition controller is a long-term working product, so the outer shell plates on both sides of the device are equipped with heat dissipation holes for convection heat dissipation, which are specifically used to evacuate the heat of the components inside the device. And the components used in the controller are all low-power products, and the heat accumulated after long-term operation is not large, which will not affect the normal operation of the device.

[0070] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the field without departing from the purpose of the present invention. These changes involve related technologies well known to those skilled in the art, which all fall within the scope of protection of the patent of the present invention.

[0071] Many other changes and modifications may be made without departing from the concept and scope of the present invention.It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
