Description

Technical Field

[0001] The invention relates to the technical field of battery monitoring, in particular to an online battery monitoring system. Background Art

[0002] The battery online monitoring system plays an important role. First, it can accurately grasp the real-time status, monitor the voltage, current, temperature, internal resistance and other parameters at all times, and clearly understand the battery charging and discharging status and health level. For example, it can promptly detect abnormal voltage of lead-acid batteries and excessive temperature of lithium batteries to prevent problems before they happen. Second, it has the ability to warn and prevent faults. It will immediately alarm when the parameters exceed the threshold. With the help of long-term monitoring data, it can also predict the performance trend, perform maintenance in advance, and avoid the deterioration of faults. Third, it helps to extend the battery life, intelligently regulate charging and discharging according to the status, and control the temperature to make the battery work in a suitable environment. Fourth, it can effectively improve the reliability and safety of the system, ensure that the backup power supply is available at critical times, prevent hidden dangers such as battery overheating and short circuit, and protect equipment and personal safety.

[0003] In the existing technology, various sensors need to be installed to monitor battery temperature, voltage and other parameters in battery monitoring scenarios. Due to the different connection locations and methods (series, parallel), and the need for battery packs to be connected in series, the connection lines are too complicated. In a limited space, the dispersed configuration of monitoring equipment will lead to a messy layout. For example, in a small cabinet of a communication base station, multiple independent devices occupy limited space, hindering the placement and operation of other components. In addition, the supporting complex lines and diverse interfaces have caused a surge in labor costs for installation and debugging, and compatibility problems have frequently occurred. Data management has also been in trouble. Data from different sources are scattered, time-consuming and labor-intensive to integrate, difficult to synchronize and compare and analyze, and troubleshooting is delayed, which can easily lead to continued deterioration of potential battery problems and endanger the stable operation of the system.

[0004] Therefore, the present invention provides a battery online monitoring system capable of realizing rapid series connection of battery groups, parallel connection of individual voltage sensors and batteries, and parallel connection of total voltage sensors and battery groups.

[0031] In this embodiment, the processor 2 has the ability to warn and prevent faults. When the parameters exceed the threshold, an alarm will be sounded immediately. With the help of long-term monitoring data, the performance trend can also be predicted. The base 131 and the top plate 132 are conductive. The staff uses a screwdriver to remove the connecting screws of the positive and negative poles of each battery in the battery pack, and then installs the device on the top of the battery pack, while ensuring that the centers of the two clamps 13 close to the processor 2 are in the same plane as the positive and negative poles of the first battery. Then the staff controls the two motors 12 to rotate forward through the processor 2, and the output ends of the two motors 12 drive the two lead screws 112 to rotate forward. The two lead screws 112 drive the three substrates 10 meshing with them to move synchronously toward the side close to the processor 2 through the meshing action. The three substrates 10 drive the clamps 13 to move toward the side close to the processor 2. The substrate 10 drives the single voltage sensor 19 to move toward the side close to the processor 2 through the bottom plate 21. When the centers of every two clamps 13 located in the same plane parallel to the plane where the processor 2 is located are The positive and negative poles of the remaining three batteries are located in the same plane. The processor 2 controls the motor 2 12 to turn off, and then controls the motor 1 3 to turn on. The output end of the motor 1 3 drives the threaded rod 9 fixedly connected to it to rotate forward, and the threaded rod 9 drives another threaded rod 9 to rotate forward through the belt and the pulley. The two threaded rods 9 drive the two moving parts 11 to move toward the side close to the single voltage sensor 19 through the meshing action. The two moving parts 11 drive the clamp 13 to move toward the side close to the single voltage sensor 19 through the substrate 10. When the clamp 13 is located at the top of the positive and negative poles of the battery, the processor 2 turns off the motor 3, thereby completing the alignment of the positive and negative poles of battery packs of different sizes. Then the staff will pass the disassembly screws through the top plate 132 and the inner side of the base 131 of each clamp 13, and use a screwdriver to fix it to the positive and negative poles of the battery, thereby completing the connection. The single voltage sensor 19 can monitor the voltage of a single battery when in use, and the total voltage sensor 20 can monitor the entire battery pack in real time.

[0032] Furthermore, the two side plates 17 are respectively located at the bottom of the main rod 4 and the back rod 5, the two moving parts 11 are respectively located on the side close to the main rod 4 and the back rod 5, the motor 3 is fixedly connected to the threaded rod 9 close to the processor 2, and a protective shell 6 is fixed on the side of the back rod 5 away from the main rod 4, and a pulley is fixed to the outer side of one end of each threaded rod 9 located at the protective shell 6, and belts are installed on the inner sides of the two pulleys.

[0033] In this embodiment, when the output end of the motor 1 3 drives the threaded rod 9 fixedly connected thereto to rotate forward, the threaded rod 9 drives another threaded rod 9 to rotate forward through the belt and the pulley, thereby realizing power transmission and simultaneous rotation of the two threaded rods 9 in the same direction.

[0034] Furthermore, the two test ends of each single voltage sensor 19 are clamped on the inner sides of two annular grooves 133 on the same vertical plane close to the bottom of the single voltage sensor 19, the inner side of the annular groove 133 that is closest to the motor and close to the base 131 is clamped with the total conductor 2 16, and the inner side of the annular groove 133 that is farthest from the motor and close to the base 131 is clamped with the total conductor 1 15, and the inner sides of the annular grooves 133 at the bottom of the other three top plates 132 at the top of the bottom wall of one group of substrates 10 are all clamped with connecting conductors 14, and the other end of each connecting conductor 14 is clamped on the inner sides of the annular grooves 133 at the bottom of the other three top plates 132 at the top of the bottom wall of another group of substrates 10, one end of the total conductor 1 15, one end of the total conductor 2 16 and both ends of the connecting conductor 14 are all located at the bottom of the pressure plate 134, and the other ends of the total conductor 1 15 and the total conductor 2 16 are respectively fixedly connected to the two test ends of the total voltage sensor 20.

[0035] In this embodiment, the connecting wire 14 ensures that the positive and negative electrodes of two adjacent batteries are connected, and the main wire 15 and the main wire 2 16 provide conditions for monitoring the total voltage of the battery group.

[0036] Furthermore, one side of the two side panels 17 is penetrated by a side hole 18, and the extrusion piece 8 is assembled to cooperate with the power of the moving part 11 to measure the temperature of different batteries. The extrusion piece 8 includes a support 81 and four round rods 83. The support 81 is fixed to the side of one of the side panels 17 away from the other side panel 17. The inner side of the side hole 18 is slidably connected with four round rods 83. A sliding rod 82 is fixed to the side of the knob 7 close to the side panel 17. The other ends of the four round rods 83 are slidably connected to the inner side of the sliding rod 82.

[0037] In this embodiment, the two lead screws 112 drive the three substrates 10 meshing therewith to move synchronously toward the side close to the processor 2 through the meshing action. At the same time, the substrate 10 drives the connecting rod 84 to move toward the side close to the processor 2 through the bottom plate 21. The connecting rod 84 drives the three round rods 83 to move toward the side close to the processor 2. The round rod 83 moves along the sliding rod 82 and the inner side of the side hole 18. After the connection is completed, the staff manually drives and rotates the two knobs 7. The two knobs 7 drive the sliding rod 82 to move toward the side close to the single voltage sensor 19 through the meshing action. The two sliding rods 82 drive the round rod 83 to move toward the side close to the single voltage sensor 19, so that the round rod 83 is away from the side of the limiting rod 111 and fits with the battery. The power used to align the clamp 13 is used to align the round rod 83 with the same battery connected to the clamp 13 at the same time, so as to monitor the temperature of the same battery.

[0038] Furthermore, the external connection end 25 includes a connecting plate 251 and a top ring plate 252, one end of the connecting plate 251 is fixedly connected to the side of the limiting rod 111 close to the processor 2, the bottom of the top ring plate 252 is fixed to the top of the connecting plate 251, a spring three is fixed to the bottom of the top ring plate 252, and a limiting ring 254 is fixed to the other end of the spring three, four through holes 253 are opened through the outer side of the top ring plate 252, and the limiting ring 254 is located on the inner side of the through hole 253, five hanging plates 22 are fixed to the bottom of the top wall of the bracket 1, the main conductor 1 15 is located on the inner side of the four hanging plates 22 close to the back rod 5, the main conductor 2 16 is located on the inner side of the hanging plate 22 close to the main rod 4, the other ends of the two external wires 26 are clamped on the outer sides of the two top ring plates 252, and the top ring plate 252 is located on the top of the limiting ring 254.

[0039] In this embodiment, the staff connects the power circuit in series with the switch through the wires, and manually pushes the two limiting rings 254 toward the top of the top ring plate 252. The two limiting rings 254 squeeze the springs and move along the inner side of the through hole 253, and clamp the other end of the wire connected to the switch on the outer side of the top ring plate 252. Then, the two limiting rings 254 are released. The two limiting rings 254 fix the power circuit on the outer side of the top ring plate 252 under the action of the springs, and then use screws and a screwdriver to penetrate through the top ring plate 252 and the inner side of the limiting rings 254 to fix the limiting rings 254 to the top ring plate 252, thereby strengthening the connection stability between the power circuit and the top ring plate 252.

[0040] Furthermore, the single voltage sensor 19 , the total voltage sensor 20 and the temperature sensor are electrically connected to the processor 2 .

[0041] Working principle: Before using this device, connect the power line in series with the switch through the wire, and the staff will manually clamp the other end of the wire connected to the switch on the outside of the top ring plate 252, and then release the two limiting rings 254, and use screws and screwdrivers to penetrate through the top ring plate 252 and the inner side of the limiting ring 254 to fix the limiting ring 254 with the top ring plate 252;

[0042] The staff uses a screwdriver to remove the connecting screws of the positive and negative poles of each battery in the battery pack, and then puts the device on the top of the battery pack, while ensuring that the center of the two clamps 13 close to the processor 2 is in the same plane as the positive and negative poles of the first battery, and then the staff controls the two motors 12 to rotate forward through the processor 2. When the center of each two clamps 13 located in the same plane parallel to the plane where the processor 2 is located is in the same plane as the positive and negative poles of the remaining three batteries, the processor 2 controls the motor 2 12 to turn off, and then controls the motor 1 3 to turn on. When the clamp 13 is located on the top of the positive and negative poles of the battery, the processor 2 turns off the motor 1 3, and then the staff passes the disassembled screws through the top plate 132 and the inner side of the base 131 of each clamp 13, and uses a screwdriver to fix it to the positive and negative poles of the battery, thereby completing the connection;

[0043] The base plate 10 drives the connecting rod 84 to move toward the side close to the processor 2 through the bottom plate 21, and the connecting rod 84 drives the three round rods 83 to move.
