Description

Technical Field

[0001] The utility model belongs to the technical field of battery monitoring, and in particular relates to a BOMS battery automatic maintenance system. Background Art

[0002] Current technology can only monitor the operating indicators of an entire battery pack; it cannot perform balancing maintenance on the battery pack. When a battery fails, it can only be manually charged and discharged using a charger and discharger, which does not fundamentally address the problem and is time-consuming and labor-intensive. The primary cause of battery failure is overcharging or undercharging of some cells during float charge due to physical differences between individual cells. Overcharged cells lose water, while undercharged cells sulfate. Therefore, balancing the battery voltage is essential. Furthermore, battery pack maintenance primarily relies on manual activation using an activation device. This method is time-consuming and labor-intensive, and most monitoring equipment can only monitor the cell voltage of the battery pack, not the internal resistance. This is a time-consuming and labor-intensive process, as most testing equipment is limited to monitoring and cannot automatically perform charging maintenance on the BOMS batteries. This significantly reduces the lifespan of the BOMS battery pack and increases operational costs. Summary of the Invention

[0029] A number of batteries 100 are provided and electrically connected to form a battery pack, and a current transformer is connected in series to the positive pole of the battery pack to avoid damage to the instrument due to excessive current. The single cell monitor 200 is electrically connected to the battery 100. The single cell monitor 200 adopts but is not limited to single cell collection and maintenance modules such as models ZHT-MM0102 and ZHT-MM0112, and the single cell monitor 200 is provided with a data acquisition interface, an operation indicator light, an alarm indicator light, an IN interface (power supply and communication) and an OUT interface (power supply and communication). The operation indicator light flashes when the operation is normal, the operation indicator light is off when the single cell monitor 200 loses power, and the alarm indicator light is on when the single cell monitor 200 fails.

[0030] The high-speed collector 300 adopts but is not limited to a high-speed convergence module of model ZHT-GSQ64. The high-speed collector 300 is provided with a plurality of input terminals of the high-speed collector 300. Each input terminal of the high-speed collector 300 can be connected to the output terminal of a single cell monitor 200. The high-speed collector 300 reads the voltage, internal resistance, and temperature of the single cell monitor 200 one by one and collects the battery pack current, voltage, and ripple voltage for analysis and processing.

[0031] A rectangular intelligent discharge screen cabinet 400 is set, an intelligent discharge control box 420 is set at the bottom of the intelligent discharge screen cabinet 400, an intelligent management host 410 is set on the upper part of the intelligent discharge screen cabinet 400, and a maintenance execution box 430 is set between the intelligent discharge control box 420 and the intelligent management host 410. Among them, the intelligent discharge control box 420 adopts but is not limited to a DC48V intelligent discharge control box, a DC220V intelligent discharge control box and other models of discharge control boxes, and the intelligent discharge control box 420 is provided with a load output terminal, and the load output terminal is connected to a DC48V intelligent discharge load, a DC220V intelligent discharge load and other models of discharge loads. The specific replacement is based on the needs of the site. The output end of the intelligent discharge control box 420 is connected to the positive and negative poles of the battery pack according to the positive and negative poles; the intelligent management host 410 adopts but is not limited to the management host of model ZHT-BOMS10, and the intelligent management host 410 is provided with a power interface, a communication port, a data import interface, etc. The power interface is connected to the DC power supply 600, the data import interface is connected to the output end of the high-speed collector 300, and the communication interface is sent to the monitoring platform 500 via a wireless network or a signal; a plurality of control buttons are provided on the maintenance execution box 430, and the output ends of the control buttons are respectively connected to the single monitor 200, the high-speed collector 300 and the intelligent discharge control box 420, and different instructions are issued by pressing different buttons.

[0032] The monitoring platform 500 uses, but is not limited to, an internal device capable of receiving communication signals, such as a desktop computer and mobile phone software; the DC power supply 600 uses a common power supply such as an indoor power supply.

[0033] Furthermore, the DC power supply 600 supplies power to the single-cell monitor 200, the high-speed collector 300, the intelligent discharge control box 420 and the intelligent management host 410. The current is distributed to the battery pack by the intelligent discharge control box 420. At the same time, the single-cell monitor 200, the high-speed collector 300 and the intelligent management host 410 start working. The single-cell monitor 200 performs real-time online monitoring of each battery 100 in the battery pack. The high-speed collector 300 collects the monitoring data of each single-cell monitor 200 and summarizes and analyzes it. The collected data includes the charge and discharge status (charging, discharging, floating charge) of the battery 100 and the battery pack, The total voltage, total current, ripple voltage, ambient temperature, each battery 100 (voltage, internal resistance, pole temperature, pole leakage), remaining capacity% of the battery 100 group, remaining discharge time, consistency of the battery 100 (range and dispersion of voltage, internal resistance and temperature), etc., are packaged and sent to the intelligent management host 410.

[0034] Furthermore, the online monitoring device 10 monitors the battery 100. When a problem occurs in the data fed back by the intelligent management host 410 in the online monitoring device 10, the automatic maintenance device 30 retrieves the data from the fault storage device 20 and manually compares it to find the same fault problem as the problem fed back by the intelligent management host 410. The maintenance execution box 430 then manually issues corresponding instructions to the maintenance execution box 430 according to the corresponding fault problem solution. The maintenance execution box 430 then assigns tasks to the single cell monitor 200, the high-speed collector 300 and the intelligent discharge control box 420, and the relevant devices perform automatic maintenance (similarly, a number of buttons are provided on the maintenance execution box 430. When the buttons corresponding to the manually issued instructions are pressed, the single cell monitor 200, the high-speed collector 300 and the intelligent discharge control box 420 are controlled to perform the corresponding instructions). At the same time, the single cell monitor 200 and the high-speed collector 300 perform monitoring summary and package and send them to the intelligent management host 410. The above steps are repeated until the data fed back by the intelligent management host 410 is normal and stops.

[0038] 3. This application accurately monitors the consistency of battery packs, quickly locates faulty batteries without discharging, and accurately determines the reliability of battery capacity.

[0039] As can be seen from the above technical solutions, this application provides a BOMS battery automatic maintenance system, which has the following functions:

[0044] 2. Online automatic balancing maintenance function:

[0045] In the floating charge state, the undercharged battery is automatically charged with a limited voltage and a small current to make up for it, so that each battery is always in the best active state, maintaining the voltage balance of each battery, preventing the battery from being sulfided due to long-term undercharge or water loss due to long-term overcharge, minimizing battery failure and extending battery service life.

[0046] 3. Liquid leakage monitoring function:

[0047] Special battery 100 pole leakage sensors are arranged around the positive and negative poles of the battery 100 to monitor the leakage of the battery 100 in real time, accurately locate the leaking battery, and prevent acid from corroding equipment and short circuit causing fire.

[0048] 4. Fault warning and alarm function:

[0050] (1) Alarm management: alarm classification statistics, current alarm confirmation, and historical alarm query;

[0051] (2) Alarm threshold setting: The alarm threshold can be set according to the battery pack operating status classification, including:

[0052] General alarms: ambient temperature alarm, battery and ambient temperature difference alarm, cell temperature extreme difference alarm, internal resistance alarm;

[0056] Charging alarm category: total voltage upper threshold, single cell voltage upper and lower thresholds, single cell temperature upper threshold;

[0057] Automatic alarm upgrade: Automatically upgrade the alarm according to the degree of exceeding the alarm threshold;

[0058] Alarm method: on-site sound and light alarm, background sound and light alarm plus push notification (APP, email, SMS, WeChat, DingTalk, etc.);

[0059] (5) Authority management: Authorization is required to set alarm thresholds, confirm current alarms, delete alarms, and other operations.

[0060] (6) Alarm level classification: According to the importance of the alarm, it is divided into general alarm, ordinary alarm, important alarm and emergency alarm;

[0061] 5. Data analysis function:

[0062] (1) Charge and discharge data analysis: It can intelligently analyze the charge and discharge data, automatically complete the charge and discharge data retrieval according to the selected time period, and generate charge and discharge records. Selecting any charge and discharge record can automatically generate a charge and discharge curve, automatically calculate and display the total voltage and the unit time voltage drop of each single cell voltage, charge and discharge time, charge and discharge capacity, voltage at the end of discharge, internal resistance, and temperature, display the single cell with the maximum and minimum voltage in the battery pack, provide analysis conclusions and maintenance suggestions, and automatically generate a charge and discharge report (Excel).

[0064] 6. Fault diagnosis function:

[0065] The system can analyze and diagnose fault alarms, providing conclusions and specific maintenance recommendations. Each alarm should visually display the alarm name, trigger value, alarm level, start time, total voltage, current, ambient temperature, and monitoring curves of each battery cell (voltage, internal resistance, and temperature) 30 minutes before and after the alarm, as well as the current total voltage, current, ambient temperature, and individual battery cell (voltage, internal resistance, and temperature) values. The system also provides a comprehensive analysis of the alarm and specific maintenance recommendations.

[0066] 7. Remote / local discharge function:

[0067] The intelligent discharge control cabinet for 100 battery groups is specially designed for automatic / remote capacity testing of 100 battery groups and integrates the following unit modules:

[0068] On-site intelligent management host 410: on-site display, alarm, analysis, diagnosis, setting, and control.

[0069] The discharge function is operated in the intelligent discharge control box 420, which has the function of performing a constant current check discharge test on the battery pack according to various discharge rates to accurately know the actual capacity of the battery.

[0070] When doing a check discharge test, five discharge termination conditions can be set at the same time:

[0071] (1) End condition for the entire group voltage; (2) End condition for the cell voltage; (3) End condition for the discharge time; (4) End condition for the discharge capacity; (5) End condition for the upper limit of the cell temperature. The ongoing test process can also be manually terminated as needed.

[0072] Before the core capacity test, the discharge equipment undergoes a self-check. If any abnormality is detected, the core capacity test cannot be performed. The equipment automatically stops discharging if the discharge module temperature is too high, the battery terminal temperature is too high, the site AC power outage occurs, or there is a network communication failure.

[0073] The system can monitor the entire discharge process and display the changes in discharge current, battery voltage, each cell voltage, and battery capacity during the discharge process in various forms such as curves and charts on the main station.

[0074] Automatic reservations can be made for remote capacity verification. At the same time, the system should be able to automatically prompt and stop conflicting reservations or reservations that do not meet conditions such as power charging and discharging.

[0075] When the remote core capacity system of the battery 100 fails or loses power, it does not affect the power supply of the DC power supply 600 to the equipment, and does not affect the normal operation of the DC load.

[0076] Based on the above solution, the input end of the high-speed collector 300 is connected to the output ends of no more than 60 of the individual monitors 200 . For example, the high-speed data collector 300 is provided with four input terminals of the high-speed data collector 300, namely COM1 (COM1-1 is connected to the negative pole, COM1-2 is connected to the positive pole), COM2 (COM2-1 is connected to the negative pole, COM2-2 is connected to the positive pole), COM3 (COM3-1 is connected to the negative pole, COM3-2 is connected to the positive pole), and COM4 (COM4-1 is connected to the negative pole, COM4-2 is connected to the positive pole). COM1-1 of COM1 is connected to the negative pole of battery 100 No. 1, COM1-2 is connected to the positive pole of battery 100 No. 60, COM2-1 of COM2 is connected to the negative pole of battery 100 No. 61, COM2-2 is connected to the positive pole of battery 100 No. 120, and so on. The battery 100 numbers must correspond and remain unchanged to avoid deviations in the displayed data. By setting the data in groups, each group of 60 facilitates collection, processing, analysis, and summary by the high-speed data collector 300.

[0077] In a preferred embodiment, in order to achieve a monitoring effect, two adjacent batteries 100 are connected to each other via a connecting bar 214 , and the connecting bar 214 is connected to the battery 100 via bolts.

[0078] Specifically, the battery 100 is connected through the connecting bar 214 to form a battery pack. The bolt passes through the connecting bar 214 and is detachably connected to the battery 100. A gasket and a spring are provided above the connecting bar 214, and both the gasket and the spring are penetrated by the bolt. The input end of the single-cell monitor 200 is electrically connected to the battery 100 in a detachable manner using, but not limited to, a bare end wire wrapped around a bolt, an end plug 210 connected to the bolt, etc. By rotating the bolt, the gasket squeezes the wire at the input end of the single-cell monitor 200 downward so that it contacts the battery 100, thereby realizing the monitoring of the battery 100 by the single-cell monitor 200.

[0079] Based on the above solution, in order to improve convenience and safety, the input end of the single monitor 200 is provided with an insert 210, and the insert 210 is detachably connected to the bolt.

[0080] Preferably, the input end of the single monitor 200 is connected by a wire and a plug 210. A C-shaped plug 210 is provided at the end of the wire away from the single monitor 200. The plug 210 is made of a material with good conductivity, and the opening of the plug 210 is not less than the bolt diameter and not more than 1.2 times the bolt diameter. The plug 210 is inserted into the bolt and located between the connecting strip 214 and the gasket. By turning the bolt downward, one end of the bolt is rotated downward to drive the spring plate and the gasket to be squeezed downward, so that the plug 210 is fixed between the connecting plate and the gasket, thereby forming a passage. Conversely, the plug 210 can be removed by turning the bolt in the opposite direction. The operation is simple and avoids the safety hazards caused by wire leakage.

[0081] In the above solution, in order to detect a fault in the battery 100 or an abnormality in the connection, a retest component is further provided at the output end of the cell monitor 200 , and the retest component is hinged to one end of the insert 210 .

[0082] Specifically, the retest component is arranged on the plug 210, and the retest component can transmit current from the wire at the input end of the cell monitor 200 to the cell monitor 200. The retest component adopts but is not limited to a lever, a magnetic valve and other devices. For example, the retest component adopts a lever type, one end of the lever is hinged to the plug 210, and the other end of the lever is connected with a bolt. When there is a problem at the connection between the cell monitor 200 and the battery 100 or the battery 100 is damaged, the lever rotates so that one end of the lever touches the bolt, thereby forming a new path. If monitoring data appears on the cell monitor 200 at this time, it means that the battery 100 is normal, and there is a problem at the connection, which needs to be reconnected; if the new path cell monitor 200 still has no monitoring data, it means that the battery 100 has a fault and needs to be replaced or repaired; the operation is simpler and more convenient, and the purpose of monitoring battery 100 faults or abnormalities at the connection is achieved.

[0083] Based on the above solution, preferably, the retest assembly includes a rotating shaft 211 and a contact plate 213, the rotating shaft 211 is rotatably connected to the insert 210, and the contact plate 213 is provided on the rotating shaft 211 and is cooperatively connected with the bolt.

[0084] Specifically, the plug 210 is rotatably connected to the rotating shaft 211 through a bearing or a card, and the plug 210 and the rotating shaft 211 are matched and connected through a conductor, and the end of the conductor away from the plug 210 is fixedly connected to the contact plate 213. The contact plate 213 is provided with but not limited to a solenoid valve, a motor push rod, and other devices that can make the contact plate 213 rotate and contact the bolt. Taking the solenoid valve as an example, the solenoid valve is electrically connected to the intelligent management host 410 and the DC power supply 600 respectively. The DC power supply 600 is controlled by the intelligent management host 410 to make current flow through the solenoid valve, so that the contact plate 213 approaches and fits tightly to the bolt to form a new path, thereby realizing the purpose of monitoring the battery 100 for faults or abnormalities in the connection, and performing targeted repairs for different fault problems, reducing labor intensity, and making the operation simpler and more convenient.

[0085] Preferably, a control motor 212 is provided at one end of the rotating shaft 211 , and the control motor 212 is electrically connected to the DC power supply 600 and the execution box 430 for maintaining the same, respectively.

[0086] Specifically, the fixed end of the control motor 212 is set on the upper end surface of the plug 210 away from the connecting piece, and the rotating shaft 211 end of the control motor 212 is connected to the rotating shaft 211 without a gear 2121. When installed, the lower part of the fixed end of the control motor 212 is detachably connected to the upper end surface of the plug 210 (connected by a screw plus a plastic expansion joint), and the connection is insulated. The top cover of the fixed end of the control motor 212 is covered with a shell 215, and the rotating shaft 211 end of the control motor 212 is provided with a missing gear 2121. A driven wheel 2122 (the driven wheel 2122 is a gear) is provided at one end of the rotating shaft 211 close to the control motor 212, and the rotating shaft 211 passes through the shell 21 5 and is connected to the control motor 212 through a gear transmission, and a return spring 2123 is provided on the rotating shaft 211. One end of the return spring 2123 is fixedly connected to the top 215 of the housing, and the other end is fixedly connected to the top of the driven wheel 2122. The control motor 212 is electrically connected to the maintenance execution box 430 and the DC power supply 600 respectively. When the control motor 212 is turned on, the missing gear 2121 rotates, driving the driven wheel 2122 to rotate, causing the rotating shaft 211 and the contact plate 213 fixedly connected to the rotating shaft 211 to rotate, so that the contact plate 213 contacts the bolt to form a path, thereby achieving the purpose of monitoring the battery 100 for faults or abnormalities in the connection. (Appendix Figure 3The missing gear 2121 and the driven wheel 2122 are on the last tooth on the side of the missing gear 2121 meshing with the driven wheel 2122, and the control motor 212 continues to rotate, then the missing gear 2121 and the driven wheel 2122 are no longer meshing) At the same time, the rotating shaft 211 rotates to squeeze the return spring 2123. When the missing gear 2121 rotates and is no longer meshing with the driven wheel 2122, the return spring 2123 drives the rotating shaft 211 to rotate in the opposite direction, thereby causing the contact plate 213 to rotate in the opposite direction and leave the bolt. Through short and multiple touches and repeated detection, the accuracy of the detection is determined, and by adjusting the diameter reduction or rotation speed of the missing gear 2121 and the driven wheel 2122, the reaction time of the maintenance execution box 430 to close the control motor 212 is given.

[0087] Based on the above solution, an arc-shaped groove is provided on one side of the contact plate 213 , and the inner wall of the groove is engaged with the bolt.

[0088] Specifically, the contact plate 213 includes a vertical portion 2131 and a horizontal portion 2132. The vertical portion 2131 is fixedly connected to the rotating shaft 211 in a vertical Z shape along one side of the rotating shaft 211 and the control motor 212. The horizontal portion 2132 extends perpendicular to the vertical portion 2131 to the end away from the plug 210, and a semicircular groove with the same diameter as the bolt is provided on the side close to the bolt. When the rotating shaft 211 drives the contact plate 213 to rotate and touches the bolt, the groove is stuck in the side wall of the bolt and fits tightly with it, thereby increasing the contact area and solving the problem of detection errors caused by point contact.

[0089] Preferably, the contact plate 213 is an arc-shaped flexible plate, and a conductive wire connected to the plug 210 is provided on one side of the arc-shaped flexible plate, and the side of the arc-shaped flexible plate provided with the conductive wire is cooperatively connected to the bolt.

[0090] Specifically, the vertical portion 2131 of the contact plate 213 is detachably connected to the rotating shaft 211 by means of bolts, buckles, etc., and the horizontal portion 2132 adopts an arc-shaped flexible plate. A row of thin copper wires is set on the side of the flexible plate close to the bolt, and the thin copper wires are fixedly connected to the plug 210 along the vertical portion 2131. The thin copper wires are longer, and part of the thin copper wires remain in the vertical portion 2131. When the rotating shaft 211 rotates, it drives the horizontal portion 2132 to rotate, so that the horizontal portion 2132 contacts the side wall of the bolt. Driven by the missing gear 2121, the rotating shaft 211 Continue to rotate so that the part of the horizontal portion 2132 that is not in contact with the side wall of the bolt rotates and wraps it, increasing the contact area and solving the problem of damage to the single monitor 200 due to the long contact period and high frequency. On the contrary, when the missing gear 2121 is no longer engaged with the driven wheel 2122 at one end of the rotating shaft 211, the return spring 2123 drives the rotating shaft 211 and the contact plate 213 fixed on the rotating shaft 211 to rotate in the opposite direction, thereby separating the contact plate 213 from the bolt, and repeating the above steps to complete multiple repeated detections, making the operation simpler and more convenient.

The description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that a person skilled in the art can make a number of adjustments and improvements without departing from the concept of the present application, and these all fall within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be based on the attached claims.
