Lead-acid batteries often have differences between battery cells, such as electrode materials, internal resistance, and self-discharge rates. Unbalanced phenomena occur during use and charging. This phenomenon is often manifested in a single single cell being severely under-voltage or over-voltage during the charging and discharging process. Therefore, a charging method for lead-acid batteries is required to adjust the charging of each single cell when charging the lead-acid battery. However, the existing lead-acid battery charging method can often only charge the entire lead-acid battery in a unified mode, causing each battery cell to remain in an under-voltage or over-voltage state after charging. After multiple charging and discharging using traditional methods, the overall capacity of the lead-acid battery pack is reduced, the life is shortened, and even the normal operation of industrial vehicles is affected.

[0017] The network 30 is used as a medium for providing a communication link between the terminal 10 and the regulator charger 20. The network 30 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0018] In addition, it should be noted that Figure 1What is shown is only one system provided by the present disclosure. In practical applications, other systems may also be included.

[0019] See next Figure 2 , Figure 2 The overall flow chart of a lead-acid battery regulation charging method provided in an embodiment of the present specification is shown. The lead-acid battery regulation charging method can be used in the server 20.

[0020] like Figure 2 As shown, the lead-acid battery regulating charging method may at least include the following steps: Step 201: Acquire initial voltage data of each single cell in a lead-acid battery, and group each of the initial voltage data based on a preset voltage mapping relationship to obtain at least one voltage deviation group.

[0021] The voltage deviation group includes at least one of the single cells and initial voltage data corresponding to each of the single cells, and the preset voltage mapping relationship includes at least two groups of voltage intervals and adjustment charging rules corresponding to each group of the voltage intervals.

[0022] In the embodiment of the present specification, after the lead-acid battery has passed the last charging and discharging working stage, it is necessary to perform initial charging on the lead-acid battery. Since each monomer battery in the lead-acid battery may have different initial voltages after being discharged in the last stage due to the monomer materials, internal resistance and other reasons. Therefore, the initial voltage of each monomer battery can be accurately measured by a voltage sensor to obtain the initial voltage data of each monomer battery in the lead-acid battery. Then, in general, the initial voltage data obtained are not the same. In order to facilitate the subsequent adjustment and charging of each monomer battery, so that the battery voltage of all monomer batteries after adjustment and charging reaches a balanced state, a voltage mapping relationship can be preset first, wherein the voltage mapping relationship includes multiple groups of voltage intervals and the corresponding adjustment charging rules in each group of voltage intervals. As an example, when there is a first voltage interval and a second voltage interval, the preset voltage mapping relationship includes the first voltage interval and its corresponding first adjustment charging rule, and the second voltage interval and its corresponding second adjustment charging rule. Further, all the initial voltage data obtained are grouped by the preset voltage mapping relationship to obtain multiple voltage deviation groups. In each voltage deviation group, there are multiple initial voltage data belonging to the voltage deviation group and single cells corresponding to the initial voltage data. As an example, when the initial voltages corresponding to single cells A, B, C, and D are obtained as a, b, c, and d, respectively, a, b, c, and d are grouped according to a preset voltage mapping relationship, and the first voltage deviation group is (Aa, Bb) and the second voltage deviation group is (Cc, Dd).

[0023] In addition to collecting the initial voltage data of each single cell, the internal resistance and temperature of each single cell can also be accurately measured. At the same time, the initial status information of the lead-acid battery pack can be recorded, such as the cumulative usage time, the number of past charge and discharge times, etc., to provide more basic data for the subsequent further adjustment of the charging strategy.

[0024] In one possible implementation manner, after obtaining the initial voltage data of each single cell in the lead-acid battery, the method further includes: When it is detected that all the initial voltage data are less than the preset voltage threshold, all the single cells are charged normally.

[0025] In the embodiment of this specification, after each single cell in the lead-acid battery has been discharged in the last round, the initial voltage data of each single cell in the lead-acid battery is collected. When it is detected that the initial voltage data of all the single cells are less than a preset voltage threshold, generally 0.05V, it can be represented that all the single cells in the lead-acid battery group are in a fully discharged state at this time, and when the initial voltage of each single cell is less than 0.05V, the voltage difference between the corresponding single cells must also be less than 0.05V, which can be regarded as that each single cell in the lead-acid battery has reached a balanced state in the initial state. Therefore, it is only necessary to perform a conventional charging procedure on all the single cells, and no subsequent adjustment charging steps are required.

[0026] In one possible implementation, the initial voltage data are grouped based on a preset voltage mapping relationship to obtain at least one voltage deviation group, including: Determine four groups of voltage intervals corresponding to the preset voltage mapping relationship; The initial voltage data are grouped according to the voltage intervals of each group to obtain a normal voltage group and three voltage deviation groups, wherein the voltage deviation groups include a low voltage deviation group, a medium voltage deviation group and a high voltage deviation group.

[0027] In the embodiment of this specification, for a group of 24V lead-acid battery packs composed of 12 single cells, after a round of discharge, the initial voltage of each single cell of the lead-acid battery pack is less than the discharge starting voltage of 2.45V, so four groups of voltage intervals can be determined in the preset voltage mapping relationship. As an example, the four groups of voltage intervals can be set as (0, 0.05), [0.05, 1.95), [1.95, 2.1), [2.1, 2.45). Then, the initial voltage data are grouped according to the voltage value to obtain a normal voltage group and three voltage deviation groups. Among them, all initial voltage data falling in the voltage interval (0, 0.05) and their corresponding single cells are defined as a normal voltage group, all initial voltage data falling in the voltage interval [0.05, 1.95) and their corresponding single cells are defined as a low voltage deviation group, all initial voltage data falling in the voltage interval [1.95, 2.1) and their corresponding single cells are defined as a medium voltage deviation group, and all initial voltage data falling in the voltage interval [2.1, 2.45) and their corresponding single cells are defined as a high voltage deviation group.

[0028] Step 202: Perform regulation charging on all the single cells included in the corresponding voltage deviation group based on each regulation charging rule.

[0029] In the embodiment of the present specification, after the initial voltage data are grouped, for each single cell, the adjustment charging rule corresponding to the voltage interval in which it is located can be queried, and the single cell can be adjusted and charged according to the adjustment charging rule. Similarly, all single cells are adjusted and charged according to their corresponding adjustment charging, so that the adjustment voltages of all single cells after adjustment charging are kept at the same balanced voltage value as much as possible, so as to facilitate subsequent unified charging.

[0030] As an example, the first voltage deviation group is (Aa, Bb), the second voltage deviation group is (Cc, Dd), the first regulating charging rule is used for single cells A and B, and the second regulating charging rule is used for single cells C and D, so that the regulated voltage of single cells A, B, C, and D after charging is maintained at V1 value as much as possible.

[0031] In one possible implementation, the step of regulating charging of all the single cells included in the corresponding voltage deviation group based on each of the regulating charging rules includes: Based on a constant current-constant voltage charging rule, regulating and charging all the single cells included in the low voltage deviation group; Based on the pulse charging rule, regulating charging is performed on all the single cells included in the medium voltage deviation group; All the single cells included in the high voltage deviation group are regulated and charged based on an intermittent charging rule.

[0032] In the embodiments of the present specification, when each voltage deviation group is divided into a low voltage deviation group, a medium voltage deviation group and a high voltage deviation group, a constant current-constant voltage charging rule can be used to regulate the charging of all the single cells contained in the low voltage deviation group. Among them, the constant current-constant voltage charging rule is to charge with a small current (such as 0.05C - 0.1C, C is the rated capacity of the battery) at the initial stage to prevent the plate from being sulfated, and to switch to constant voltage charging when the voltage rises to a preset value. As an example, for a 24V lead-acid battery pack, constant current-constant voltage charging can first use a 0.06C current constant current for charging, and when it is detected that the single cell voltage rises to 2.4V, it is switched to constant voltage charging until the single cell voltage rises to 2.45V and charging is suspended.

[0033] At the same time, the pulse charging rule is used to regulate the charging of all single cells included in the medium voltage deviation group. Among them, the pulse charging rule is to use pulse charging, and the pulse width and frequency are dynamically adjusted according to the state of the single cell, so as to reduce the heating of the battery while ensuring the charging efficiency. As an example, for a 24V lead-acid battery pack, the pulse charging rule can use 0.04C current pulse charging, with the initial pulse width set to 5ms and the frequency to 800Hz. According to the voltage change detected during the charging process, the pulse width is dynamically adjusted between 3ms-8ms and the frequency is between 600Hz-1000Hz until the single cell voltage rises to 2.45V and the charging is suspended.

[0034] At the same time, the intermittent charging rule is used to regulate the charging of all the single cells contained in the high voltage deviation group. Among them, the intermittent charging rule is to first perform trickle discharge, adjust the voltage to a reasonable range, and then replenish the power by intermittent charging to avoid voltage overcharging. As an example, for a 24V lead-acid battery pack, the intermittent charging rule can first use 0.02C current pulse charging, and also set the initial pulse width to 5ms and the frequency to 800Hz. According to the voltage change detected during the charging process, the pulse width is dynamically adjusted between 3ms-8ms and the frequency is between 600Hz-1000Hz. Charge for 10 minutes, pause for 2 minutes, and repeat until the single cell voltage rises to 2.45V and charging is suspended.

[0035] Step 203: obtaining the regulated voltage of each single cell after regulated charging, and performing conventional charging on all the single cells according to all the regulated voltages.

[0036] In the embodiment of this specification, after all the single cells are regulated and charged, due to the floating pressure of the lead-acid battery, it is necessary to regulate and charge again and then stand for a preset time, and then obtain the regulated voltage of each single cell through the voltage sensor. Then, the voltage difference of all the regulated voltages can be judged. If the voltage difference meets the preset voltage difference requirement, it means that the regulated voltage of each single cell meets the balance requirement, and all the single cells can be uniformly charged with conventional charging steps to complete the subsequent charging process. If the voltage difference does not meet the preset voltage difference requirement, the cyclic regulation charging steps are performed until the regulated voltage difference meets the preset voltage difference requirement.

[0037] Optionally, after obtaining the regulated voltage of each single cell, the voltage variance of all regulated voltages may be determined first, and the voltage variance is compared with a preset variance requirement to determine whether the regulated voltage of each single cell meets the balancing requirement.

[0038] In one possible implementation, obtaining the regulated voltage of each of the single cells after regulated charging, and performing conventional charging on all of the single cells according to all of the regulated voltages, includes: Obtaining the regulated voltage of each of the single cells after regulated charging, and determining the maximum regulated voltage difference among all the regulated voltages based on a voltage difference maximum value algorithm; All the single cells are normally charged based on the maximum regulated voltage difference.

[0039] In the embodiment of the present specification, after obtaining the regulated voltage of each single cell after the regulated charging, the maximum and minimum values ​​of each regulated voltage are first determined by the voltage difference maximum value algorithm, and then the maximum regulated value is subtracted from the minimum regulated voltage value to obtain the maximum regulated voltage difference of all regulated voltages. Further, it is determined whether the balancing requirement is met based on the obtained maximum regulated voltage difference. If it is met, all single cells are subjected to a unified conventional charging step to complete the subsequent charging process. If it is not met, each single cell can be subjected to a cyclic voltage regulation step and a cyclic regulated charging step until the regulated voltage difference meets the preset voltage difference requirement.

[0040] In one possible implementation, the conventional charging of all the single cells based on the maximum regulated voltage difference includes: Comparing the maximum regulated voltage difference with a preset voltage difference threshold to obtain a comparison result; When the comparison result indicates that the maximum regulated voltage difference is not greater than the preset voltage difference threshold, conventionally charging all the single cells; When the comparison result indicates that the maximum regulated voltage difference is greater than the preset voltage difference threshold, secondary regulation charging is performed on all the single cells.

[0041] In the embodiments of the present specification, a preset voltage difference threshold value may be determined first, which is generally set to 0.05V. Then, the maximum regulated voltage difference is compared with the preset voltage difference threshold value by subtraction calculation. When the comparison result is not a positive number, it indicates that the maximum regulated voltage difference is not greater than the preset voltage difference threshold value. At this time, the regulated voltages of all single cells meet the equalization requirements, and all single cells are subjected to uniform conventional charging steps to complete the subsequent charging process. When the comparison result is a positive number, it indicates that the maximum regulated voltage difference is greater than the preset voltage difference threshold value. The regulated voltages of all single cells cannot all meet the equalization requirements, and all single cells need to be regulated and charged a second time. Among them, the steps and principles of the secondary regulation charging are the same as those of the first regulation charging.

[0042] In one embodiment, the method further comprises: Collecting temperature data of each of the single cells in real time; When the temperature data is greater than a preset temperature threshold, charging of the single battery corresponding to the temperature data is immediately stopped.

[0043] In the embodiment of this specification, in addition to obtaining the voltage data of each single cell, the temperature data of each single cell can also be collected in real time through the temperature sensor. Then, a temperature threshold is preset. For a 24V lead-acid battery pack, the preset temperature threshold is set to 45°C. If it is detected that the temperature data of a single cell is greater than 45°C during the real-time charging process, the charging of the single cell corresponding to the temperature data is immediately stopped.

[0044] After the initial voltage data is obtained and before the data is grouped, the battery temperature affects the voltage and internal resistance measurements. Therefore, the temperature compensation coefficient can be used to perform temperature compensation correction on the corresponding initial voltage data based on the difference between the initial single cell temperature data and the standard temperature (such as 25°C) to improve the accuracy of subsequent grouping.
