Description

Lead-acid battery activation system, method, electronic device, and storage medium
Technical Field
The invention relates to the technical field of activation of lead-acid storage batteries, in particular to a system and a method for activating a lead-acid storage battery, electronic equipment and a storage medium.
Background
The lead-acid storage battery has the advantages of low price, mature preparation technology, excellent high and low temperature performance, stability, reliability, high safety and the like, so that the lead-acid storage battery is widely applied to large-scale machine rooms, information centers and other scenes.
In practical application, the lead-acid storage battery can be put into use only when the consistency of the lead-acid storage battery meets the requirement. The consistency refers to that after the single batteries with the same specification and model form a battery pack, parameters such as voltage, charge quantity, capacity, recession rate, internal resistance and change rate thereof, service life, temperature influence, self-discharge rate and the like have certain differences. That is to say, the parameter errors between different lead-acid storage battery cells in the same lead-acid storage battery pack can be used within the error allowable range.
In general, the difference in consistency is mainly caused by two reasons: on one hand, the original difference of lead-acid storage battery monomers caused by the difference of the manufacturing process; another aspect is the difference in lead acid battery cell degradation caused by environmental differences in use. Therefore, in an actual use environment, the lead-acid storage battery pack is used for a period of time, and the lead-acid storage battery pack is degraded, so that the problem of poor consistency is caused. If the retired lead-acid storage battery pack is to be reused, the lead-acid storage battery pack is necessarily required to be activated.
The traditional activation of the storage battery is mainly achieved by manually charging and discharging the whole lead-acid storage battery for many times to activate the storage battery. This results in a large amount of manual intervention required for the entire activation process, which is costly in labor; in addition, the conventional activation of the storage battery usually adopts a heating load (e.g., a heating resistor) to discharge, so as to convert electric energy into heat energy, which not only wastes a large amount of electric energy, but also has potential safety hazard.

Fig. 1 is a schematic structural diagram of an activation system of a lead-acid battery according to an embodiment of the present invention. Referring to fig. 1, the lead-acid battery activation system includes: a DC/AC module 11, a CPU control module 12, an energy switching matrix 13, a cell charging module 14, and a cell discharging module 15.
The first end of the DC/AC module 11 is connected with a power grid, and the second end is connected with a lead-acid storage battery pack 16 to be activated, and is used for converting alternating-current voltage into direct-current charging voltage or converting direct-current discharging voltage into alternating-current voltage.
The third end of the DC/AC module 11 is connected with a power supply port of the CPU control module 12; the first communication port of the CPU control module 12 is connected to the communication port of the DC/AC module 11, the communication port of the energy switching matrix 13, the communication port of the cell charging module 14, and the communication port of the cell discharging module 15, respectively.
The first switching end of the energy switching matrix 12 is connected to each battery cell in the lead-acid battery pack 16 to be activated, and the second switching end is connected to the cell charging module 14 and the cell discharging module 15.
The DC/AC module 11 is respectively connected with a power grid and a lead-acid storage battery pack 16 to be activated, so that on one hand, alternating current can be obtained from the power grid and converted into direct current charging voltage to charge the lead-acid storage battery pack 16 to be activated; on the other hand, the direct-current discharge voltage of the lead-acid storage battery pack 16 to be activated can be obtained during discharging and converted into alternating-current voltage to be fed back to the power grid, so that energy waste is avoided.
The CPU control module 12 is respectively connected with the communication end of the DC/AC module 11, the communication end of the energy switching matrix 13, the communication end of the single charging module 14 and the communication end of the single discharging module 15, and can send instructions to the modules in real time, so that the modules perform charging, discharging or switching actions and the like according to the instructions to complete activation work, manual work is not needed, labor cost can be greatly reduced, and activation efficiency is improved.
Furthermore, the CPU control module 12 may also monitor the operation condition of each module in real time, and monitor the output voltage and output current of the DC/AC module 11, the switching condition of the energy switching matrix 13, the charging rate of the cell charging module 14, the discharging rate of the cell discharging module 15, and the like in real time, so as to update the instructions according to the operation condition of each module in real time.
The lead-acid storage battery pack 16 to be activated is formed by sequentially connecting N battery monomers in series, wherein N is greater than or equal to 1. The energy switching matrix 13 is respectively connected to each single battery, the single charging module 14 and the single discharging module 15 in the lead-acid storage battery pack to be activated, and each single battery can be charged and discharged by using the single charging module 14 and the single discharging module 15. That is to say, this lead acid battery activation system not only can treat the lead acid battery that activates and carry out whole charge and whole discharge, can also carry out monomer charge and monomer discharge to each battery monomer to promote the activation effect.
In a possible implementation manner, the first switching end of the energy switching matrix 13 is provided with at least two switching interfaces, and every two adjacent switching interfaces are respectively and sequentially connected with the positive electrode and the negative electrode of each battery cell in the lead-acid battery pack 16 to be activated correspondingly.
A second switching end of the energy switching matrix 13 is provided with a positive electrode interface and a negative electrode interface, and the positive electrode interface is respectively connected with the positive electrode of the monomer charging module 14 and the positive electrode of the monomer discharging module 15; the negative electrode interface is respectively connected with the negative electrode of the monomer charging module 14 and the negative electrode of the monomer discharging module 15.
The communication end of the energy switching matrix 13 is connected to a first communication port of the CPU control module 12, and is configured to connect a corresponding battery cell in the lead-acid battery pack 16 to be activated to the cell charging module 14 and the cell discharging module 15 according to an instruction of the CPU control module 12.
Each switching interface in the first switching end of the energy switching matrix 13 is sequentially connected with the anode and the cathode of each battery monomer in the lead-acid storage battery pack 16 to be activated, the anode interface in the second switching end is connected to the anode of the monomer charging module 14 and the anode of the monomer discharging module 15 through a charging and discharging anode bus, and the cathode interface in the second switching end is connected to the cathode of the monomer charging module 14 and the cathode of the monomer discharging module 15 through a charging and discharging cathode bus. The communication end of the energy switching matrix 13 is connected to the first communication port of the CPU control module 12, so that the energy switching matrix 13 can correspondingly connect the positive and negative electrodes of any battery cell to be charged or discharged in the lead-acid battery pack 16 to be activated to the positive and negative electrodes of the cell charging module 14 and the positive and negative electrodes of the cell discharging module 15 according to the instruction of the CPU control module 12, thereby charging or discharging the battery cell.
The communication end of the cell charging module 14 and the communication end of the cell discharging module 15 are both connected to the first communication port of the CPU control module. When the single battery is charged, the CPU control module controls the single charging module 14 to be started, the single discharging module 15 is closed, and the single charging module 14 charges the single battery through the charging and discharging positive bus and the charging and discharging negative bus. Similarly, when discharging the single battery, the CPU control module controls the single discharge module 15 to be turned on, the single charge module 14 to be turned off, and the single discharge module 15 discharges the single battery through the charge-discharge positive bus and the charge-discharge negative bus; when the battery cells do not need to be charged or discharged, the cell discharging module 15 and the cell charging module 14 are controlled to be turned off.
The single charging module 14 may have a built-in micro programmable power supply for being turned on or off according to an instruction of the CPU control module 12, and at the same time, may adjust its output voltage and output current according to an instruction of the CPU control module 12 in an on state, so as to ensure that the single charging is performed according to a preset charging rate. In general, for a 2V cell, the upper limit of the charging voltage is 2.5V, and the chemical reaction of electrolytic water is more easily generated under the charging voltage of 2.5V, which is beneficial to the activation of the cell. Therefore, the single charging module 14 of the invention can be provided with an output voltage of 2.5V and an output current of 50A to meet the charging requirement of the battery single.
The cell discharging module 15 may have an adjustable load built therein, and is configured to adjust its own conduction degree according to an instruction of the CPU control module 12, so as to control the discharging rate of the battery cell. The instruction can comprise at least two PWM signals, the micro-programmed power supply can adjust the output voltage and the output current of the micro-programmed power supply according to the duty ratio of one PWM signal, and particularly, when the duty ratio of the PWM signal is zero, the micro-programmed power supply is turned off and is not charged any more. The adjustable load can adjust the conduction degree of the adjustable load according to the duty ratio of another PWM signal, and particularly, when the duty ratio of the PWM signal is zero, the adjustable load is closed and does not discharge any more.
The activation of the lead-acid storage battery is a process of substantially repeatedly charging and discharging the lead-acid storage battery to improve the discharge capacity of the lead-acid storage battery. Electrolyte in the lead-acid storage battery can be effectively activated through repeated charging and discharging operations, so that the discharge capacity of the lead-acid storage battery is improved, and the failed lead-acid storage battery with the discharge capacity lower than the threshold value can be reused.
In the rated battery capacity range, the larger the charging capacity of the lead-acid storage battery pack to be activated is, the larger the discharging capacity of the lead-acid storage battery pack to be activated is, and accordingly, the discharge capacity of the lead-acid storage battery pack to be activated is, so that the discharge capacity is quickly recovered, and a better activation effect is obtained. On the other hand, if sufficient charge and discharge cannot be performed, sufficient activation cannot be performed. Ideally, the lead-acid storage battery pack to be activated needs to be fully charged during each charging, and the electric quantity in the lead-acid storage battery pack to be activated needs to be discharged during discharging. However, when the lead-acid battery pack 16 to be activated is wholly charged or discharged, as long as any battery cell in the lead-acid battery pack 16 to be activated is fully charged or discharged, a large impedance is generated to the charging circuit or the discharging circuit, so that the whole lead-acid battery pack 16 to be activated cannot be charged or discharged continuously. Due to the poor consistency of the lead-acid battery 16 to be activated, it is likely that individual or partial cells are charged or discharged in advance, and the remaining cells that are not charged or discharged cannot continue to be charged or discharged. This prevents the entire lead-acid battery pack 16 to be activated from being effectively activated. Therefore, in the embodiment of the present invention, the energy switching matrix 13, the single charging module 14, and the single charging module 15 are provided, and are used to connect a battery cell that is not fully charged or discharged in the lead-acid storage battery 16 to be activated to the single charging module 14 and the single charging module 15, so as to further charge and discharge the battery cell, so as to improve the activation effect.
In one possible implementation, referring to fig. 2, the energy switching matrix 13 comprises at least two switching modules 131.
The first ends of all the switching modules 131 are sequentially connected with the positive electrode and the negative electrode of each battery monomer in the lead-acid storage battery pack 16 to be activated, and the second ends of all the switching modules 131 are connected with the positive electrode of the monomer charging module 14 and the positive electrode of the monomer discharging module 15; the third ends of all the switching modules 131 are connected to the negative electrode of the cell charging module 14 and the negative electrode of the cell discharging module 15, and the control ends of all the switching modules 131 are connected to the first communication port of the CPU control module 12.
The switching module 131 may switch and connect the first end to the second end or the third end according to an instruction of the CPU control module, so as to correspondingly connect the positive and negative electrodes of the battery cell to be charged or discharged to the positive and negative electrodes of the cell charging module 14 and the cell discharging module 15.
In practical applications, when a certain single battery in the lead-acid battery pack 16 to be activated is charged and discharged, the first end of the switching module connected to the positive electrode of the single battery is connected to the third end thereof, and the first end of the switching module connected to the negative electrode of the single battery is connected to the second end thereof, so that the positive electrode and the negative electrode of the single battery are correspondingly connected to the positive electrode and the negative electrode of the single charging module 14 and the single discharging module 15.
In one possible implementation, referring to fig. 3, the switching module 131 is a relay set, each relay set including a first relay 1311 and a second relay 1312.
For each switching module 131, a first end of the first relay 1311 and a first end of the second relay 1312 are connected to the first communication port of the CPU control module 12.
In the first switching module, a second end of the first relay 1311 is connected to a positive electrode of a first battery cell in the lead-acid storage battery pack 16 to be activated, and a third end of the first relay 1311 is connected to a positive electrode of the cell charging module 14 and a positive electrode of the cell discharging module 15. The positive electrode of the first cell is the positive electrode of the entire lead-acid battery pack 16 to be activated.
In the last switching module, the second end of the second relay 1312 is connected to the negative electrode of the last battery cell in the lead-acid battery pack 16 to be activated, and the third end of the second relay 1312 is connected to the negative electrodes of the cell charging module 14 and the cell discharging module 15. The negative electrode of the last cell is the negative electrode of the entire lead-acid battery pack 16 to be activated.
In the remaining switching modules, a second end of each first relay 1311 is sequentially connected to a positive electrode and a negative electrode of a remaining battery cell in the lead-acid battery pack 16 to be activated, a second end of each first relay 1311 is further correspondingly connected to a second end of each second relay 1312, a third end of each first relay 1311 is connected to a positive electrode of the battery cell charging module 14 and a positive electrode of the battery cell discharging module 15, and a third end of each second relay 1312 is connected to a negative electrode of the battery cell charging module 14 and a negative electrode of the battery cell discharging module 15.
The first end of the first relay 1311 and the first end of the second relay 1312 are both connected to the first communication port of the CPU control module 12, and are configured to receive an instruction of the CPU control module 12, where the instruction may be a level signal. And controlling the self contact to be disconnected or attracted according to the level signal, so that the second end and the third end of the relay are disconnected or connected.
Taking the first relay as an example, when the first relay receives a high level signal, the first relay controls the contact of the first relay to be attracted, so that the second end of the first relay is connected with the third end of the first relay; when the first relay receives the low level signal, the self contact is controlled to be disconnected, so that the second end of the first relay is disconnected with the third end of the first relay.
For example, when it is desired to charge or discharge the first battery cell, the CPU control module 12 sends a high signal to the first relay in the first switching module, so that the positive electrode of the first battery cell is connected to the positive electrodes of the cell charging module 14 and the cell discharging module 15, and the CPU control module 12 also sends a low signal to the first relay in the second switching module, and sends a high signal to the second relay in the second switching module, so that the negative electrode of the first battery cell is connected to the negative electrodes of the cell charging module 14 and the cell discharging module 15. When charging is needed, the CPU control module 12 controls the monomer charging module 14 to be opened, and the monomer discharging module 15 to be closed; when discharging is needed, the CPU control module 12 controls the cell discharging module 15 to be turned on, and the cell charging module 14 to be turned off.
Compared with other power switch elements, the relay has better isolation, can resist high voltage and bear large current, has long electric shock service life, and completely meets the use requirement of a storage battery activation scene. Therefore, the embodiment of the invention adopts the relay to construct the switching module. The user can also use other power switches to construct the switching module according to the requirement of the user.
In one possible implementation, referring to fig. 4, the dc/AC module 11 comprises: a bidirectional inverter 111, a DC/DC converter 112 and a BUCK-BOOST bidirectional energy transfer circuit 113.
The first end of the bidirectional converter 111 is connected to the grid, and the second end is connected to the first end of the DC/DC converter 112, for realizing the interconversion between the alternating voltage and the first direct voltage.

Meanwhile, the CPU control module 12 is connected to the communication terminal of the DC/AC module 11, the communication terminal of the energy switching matrix 13, the communication terminal of the cell charging module 14, and the communication terminal of the cell discharging module 15, respectively, and can send instructions to each module in real time, so that each module performs charging, discharging, or switching according to the instructions to complete activation, without the help of labor, thereby greatly reducing labor cost and improving activation efficiency. Moreover, by arranging the energy switching matrix, the single charging module and the single discharging module, each battery cell can be further charged and discharged under the condition that the overall charging or the overall discharging cannot be continued, so that active substances in electrolyte in the lead-acid storage battery pack 16 to be activated are deeply activated, and the activation effect is improved.
Based on the lead-acid storage battery activation system, the invention also provides a lead-acid storage battery activation method. Fig. 6 is a flowchart of an implementation of the method for activating a lead-acid battery according to the embodiment of the present invention, which is detailed as follows:
and 601, charging the lead-acid storage battery pack to be activated, and monitoring the charging capacity in real time.
In practical application, the DC/AC module can be used for integrally charging the lead-acid storage battery to be activated, and the CPU control module is used for monitoring the charging capacity in real time. The CPU control module can monitor the output voltage and the output current of the DC/AC module in real time, and the charging capacity is calculated through the output voltage, the output current and the charging time.
Step 602, when the charging capacity meets a preset condition, sequentially performing monomer charging on each battery cell with the charging capacity smaller than a first preset value.
Optionally, step 602 may include:
and when the increment of the charging capacity is smaller than or equal to a third preset value, sequentially acquiring the current charging capacity of each battery monomer in the lead-acid storage battery pack to be activated.
And sequentially carrying out monomer charging on each battery monomer with the current charging capacity smaller than the first preset value.
Ideally, when the increase of the charging capacity is equal to zero, the battery cells which are not fully charged are sequentially charged until each battery cell is fully charged. In practical application, in order to improve the activation efficiency, when the charging capacity is not increased obviously any more, that is, the increase of the charging capacity is smaller than the third preset value, it is indicated that the charging operation of the lead-acid storage battery pack to be activated at this time reaches a bottleneck, and effective charging cannot be performed any more. At this time, the charging capacity of each battery cell needs to be obtained, and whether the charging capacity of each battery cell is larger than a first preset value or not is detected. And continuing the cell charging for the battery cell with the charging capacity smaller than the first preset value. The first preset value and the third preset value may be set by a user, which is not specifically limited in the embodiment of the present invention.
Step 603, after all the battery monomers are charged, discharging the lead-acid storage battery pack to be activated, and detecting the discharge capacity after the discharge is finished.
In practical application, the DC/AC module can be used for integrally discharging the lead-acid storage battery to be activated, and the discharge capacity is detected after the discharge is finished.
And step 604, when the discharge capacity is smaller than a second preset value, performing monomer discharge on each battery monomer in sequence.
And if the discharge capacity is smaller than the second preset value, the lead-acid storage battery pack to be activated does not reach the activation standard, but the whole lead-acid storage battery pack to be activated cannot continue to discharge at the moment. Therefore, the energy switching matrix, the single charging module and the single discharging module are used for sequentially carrying out single discharging on each single battery, and preparation is made for next charging.
And the discharge capacity is greater than or equal to a second preset value, which indicates that the lead-acid storage battery to be activated reaches the activation standard, and the lead-acid storage battery can be secondarily utilized without being continuously activated. The second preset value can be set by the user. In general, when the discharge capacity is 80% or more of the rated discharge capacity, it is determined that the activation criterion is met.
And 605, after the monomer discharge is finished, skipping to the step of charging the lead-acid storage battery pack to be activated and monitoring the charge capacity in real time, and continuing to execute the subsequent steps until the discharge capacity is greater than or equal to a second preset value, and then completing the activation.
And when the monomer discharge is finished, skipping to the step 601, carrying out integral charging on the whole lead-acid storage battery pack to be activated again, continuing to execute the subsequent steps, starting a new round of charge-discharge operation, and completing the activation until the discharge capacity of the lead-acid storage battery pack to be activated during integral discharge is greater than or equal to a second preset value.
The embodiment of the invention charges the lead-acid storage battery to be activated and monitors the charging capacity in real time; when the charging capacity meets a preset condition, sequentially carrying out monomer charging on each battery monomer with the charging capacity smaller than a first preset value; after all the battery monomers are charged, discharging the lead-acid storage battery pack to be activated, and detecting the discharge capacity after the discharge is finished; when the discharge capacity is smaller than a second preset value, monomer discharge is carried out on each battery monomer in sequence; and after the monomer discharge is finished, skipping to the step of charging the lead-acid storage battery to be activated and monitoring the charge capacity in real time, and continuing to execute the subsequent steps until the discharge capacity is greater than or equal to a second preset value, so that the activation is completed, the whole activation process is more intelligent, the labor cost is reduced, and the working efficiency is improved. And on the basis of integral charging and integral discharging, monomer charging and monomer discharging are further carried out, so that active substances in electrolyte in the lead-acid storage battery to be activated are deeply activated, the discharge capacity of the lead-acid storage battery to be activated is quickly recovered, and the activation effect is improved.
