DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this specification.

[0021] It should be noted that the terms "first", "second", etc. in the description and claims of the embodiments of this specification and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0022] The battery activation data processing method provided in some embodiments of the present specification performs constant current pulse charging and discharging on the battery to be activated, samples the voltage of the battery to be activated during the charging and discharging process, calculates the sulfidation degree of the battery to be activated based on the sampled voltage, and then adjusts the pulse frequency of charging and discharging in the next activation cycle based on the sulfidation degree, so that the pulse frequency of charging and discharging is adapted to the sulfidation degree of the battery, thereby improving the activation efficiency of the battery.

[0023] The following describes a road straightening data processing method according to an embodiment of the present specification. Figure 1 This is a flow chart of a battery activation data processing method provided by an embodiment of this specification. This specification provides method operation steps such as the embodiment or flow chart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many steps, and does not represent the only execution order. When the actual system or server product is executed, the method sequence shown in the embodiment or the accompanying drawings may be executed or executed in parallel (for example, in a parallel processor or multi-threaded processing environment). The method can be applied to terminals such as computers, tablet computers, smart phones, smart wearable devices, and vehicle-mounted devices. Of course, it can also be applied to servers according to actual needs, and the embodiments of this specification do not specifically limit this. Specifically, Figure 1 As shown, the method may include: S102: During the process of constant current pulse charging and discharging of the battery to be activated, sampling the voltage of the battery to be activated.

[0024] In the specific implementation process, the battery that needs to be activated in the embodiments of this specification can be used as a battery to be activated, and the battery to be activated can be subjected to constant current pulse charge and discharge treatment, such as: the battery to be activated can be subjected to constant current pulse charge and discharge in a peak charge and discharge manner. Figure 2 This is a waveform diagram of charging and discharging in a scenario example of this manual, such as Figure 2 As shown, in some scenario examples of this specification, a duty cycle of 1%-1.5% can be used to perform pulse charging and discharging on the battery to be activated. For example, taking 1kHz charging as an example, it is equivalent to charging once every 1ms, but the charging time only accounts for 1.5% of that 1ms, that is, 15us. The battery to be activated is activated by constant current pulse charging and discharging. Using constant current mode charging and discharging, the voltage fluctuation during the charging and discharging process can directly reflect the change in the internal resistance of the battery, that is, it reflects the degree of sulfidation of the battery. Therefore, in the process of charging and discharging the battery to be activated, the voltage of the battery to be activated is sampled, and the voltage data of the battery to be activated is collected during each pulse charging. Specifically, in some embodiments of this specification, during the charging and discharging process, the battery voltage can be sampled by a high-speed ADC (analog to digital converter).

[0025] S104: Calculate the maximum voltage difference of the battery to be activated during the activation cycle according to the voltage obtained by sampling.

[0026] In the specific implementation process, the maximum voltage difference of the battery to be activated within the activation cycle can be calculated based on the voltage obtained by sampling, wherein the activation cycle can be understood as the time of charging and discharging during each round of activation, and the specific time can be set according to actual needs, such as: it can be set to 1 hour, half an hour, etc., and the specific time of the activation cycle is not limited in the embodiments of this specification. It has been verified that if the activation cycle is too short, the activation effect cannot be fed back in time, and if the time is too long, the response speed of the subsequent activation cycle cannot keep up. In some scene examples of this specification, the activation cycle can be set to 1 hour, which can not only ensure that the activation effect can be fed back in time, but also can timely adjust the pulse frequency of the subsequent activation according to the feedback activation effect, thereby improving the activation efficiency.

[0027] The maximum voltage difference can be understood as the difference between the maximum voltage or the minimum voltage during the activation cycle. It is mainly used to characterize the voltage fluctuation of the battery to be activated during the charging and discharging process. The change in the voltage in the battery during charging and discharging can reflect the change in the internal resistance of the battery, and then reflect the degree of sulfidation of the battery.

[0028] In some embodiments of the present specification, the step of calculating the maximum voltage difference of the battery to be activated within a preset time according to the voltage obtained by sampling includes: According to the voltage obtained by sampling, a single maximum voltage difference between the highest voltage and the lowest voltage of the battery to be activated during each pulse charging in the activation cycle is obtained; According to the single maximum voltage difference during each pulse charging in the activation period, the average fluctuation voltage difference in the activation period is calculated, and the average fluctuation voltage difference is used as the maximum voltage difference.

[0029] In the specific implementation process, when performing voltage sampling, the highest voltage and the lowest voltage of the battery to be activated during each pulse charging in the activation cycle can be recorded, and the single maximum voltage difference during each pulse charging can be calculated. Then, based on all the single maximum voltage differences in the activation cycle, the average fluctuating voltage difference in the activation cycle is calculated, and the average fluctuating voltage difference is used as the maximum voltage difference. For example: the activation cycle is 1 hour, pulse charging is performed every 1ms, and the single maximum voltage difference within 1ms of each pulse charging is counted, and then all the single maximum voltage differences within 1 hour are averaged to obtain the average fluctuating voltage difference, and the average fluctuating voltage difference is used as the maximum voltage difference.

[0030] The embodiments of this specification obtain the maximum voltage difference by averaging the voltage changes of the battery to be activated during charging and discharging in the activation cycle, so that the voltage change can better reflect the change in the internal resistance of the battery, thereby improving the accuracy of the subsequent calculation of the degree of battery sulfidation, and further improving the accuracy of the adjustment of the pulse frequency during activation charging and discharging, laying a theoretical foundation for improving the battery activation efficiency.

[0031] S106: Calculating the current sulfation degree of the battery to be activated at the end of the current activation cycle according to the maximum voltage difference.

[0032] In a specific implementation process, after obtaining the maximum voltage difference of the battery to be activated during the activation cycle, the current degree of sulfation of the battery to be activated at the end of the current activation cycle can be calculated based on the maximum voltage difference. The voltage change of the battery during the charging and discharging process can reflect the change of the internal resistance of the battery, which is an important factor affecting the degree of sulfation of the battery. Therefore, based on the maximum voltage difference of the battery to be activated during the activation cycle, the current degree of sulfation of the battery to be activated at the end of the current activation cycle can be calculated. Specifically, the mapping relationship between the voltage change of the battery and the degree of sulfation of the battery can be obtained through experiments, expert experience or machine learning algorithms, and then the current degree of sulfation of the battery to be activated at the end of the current activation cycle can be calculated based on the maximum voltage difference of the battery to be activated during the activation cycle.

[0033] In some embodiments of this specification, the calculating the current sulfation degree of the battery to be activated at the end of the current activation cycle according to the maximum voltage difference includes: The product of the maximum voltage difference and a preset proportionality coefficient is used as the current sulfation degree of the battery to be activated at the end of the current activation cycle; the preset proportionality coefficient is used to characterize the internal resistance variation characteristics of the battery to be activated.

[0034] In the specific implementation process, the embodiment of this specification sets a preset proportionality coefficient based on the internal resistance characteristics of the battery to be activated, and the product of the preset proportionality coefficient and the maximum voltage difference of the battery to be activated during the activation cycle is used as the current sulfation degree of the battery to be activated at the end of the activation cycle. The preset proportionality coefficient can be calculated using the following formula: k = (R(now) - R(min)) / (R(max) - R(min)) / (V(max initial) - V(min initial)) Wherein, k is the preset proportional coefficient, R(now) is the internal resistance of the battery to be activated before activation; R(min) is the internal resistance of the battery to be activated when it leaves the factory, R(max) is the internal resistance of the battery to be activated when it reaches the scrap level, V(max initial) is the maximum voltage of the battery to be activated when charging and discharging before activation, and V(min initial) is the minimum voltage of the battery to be activated when charging and discharging before activation.

[0035] R(now) can be obtained by detection before battery activation, R(min) and R(max) can be obtained based on the factory parameters of the battery, and V(max initial) and V(min initial) can be obtained based on the sampled voltage when the battery to be activated is charged and discharged in the first round of activation cycle.

[0036] The embodiments of this specification set a preset proportional coefficient of the battery to be activated based on the internal resistance characteristic data of the battery to be activated before activation. Based on the preset proportional coefficient and the maximum voltage difference of the battery to be activated during the activation cycle, the sulfation degree of the battery to be activated at the end of the activation cycle can be more accurately reflected, thereby laying an accurate data foundation for adjusting the pulse frequency of charge and discharge during subsequent activation.

[0037] S108: When the sulfidation degree meets the preset activation requirement, based on the current sulfidation degree and the pulse frequency of charge and discharge in the current activation cycle, determining the adjustment pulse frequency of charge and discharge in the next activation cycle.

[0038] In a specific implementation process, after obtaining the sulfidation degree of the battery to be activated at the end of the current activation cycle, first determine whether the battery to be activated meets the preset activation requirements based on the sulfidation degree. If it does, it is necessary to continue the activation operation on the battery to be activated. The adjustment pulse frequency to be used for charging and discharging in the next activation cycle can be determined based on the sulfidation degree and the pulse frequency of charging and discharging used in the current activation cycle. In other words, the embodiment of this specification calculates the sulfidation degree of the battery in each activation cycle, and then adjusts the pulse frequency of the next activation cycle, so that the pulse frequency used for activation matches the sulfidation degree of the battery to be activated, thereby improving the efficiency of activation.

[0039] Among them, the method for determining the adjustment pulse frequency of the next activation cycle can be selected according to actual needs, such as: the mapping relationship between the degree of sulfidation of the battery and the pulse frequency required for activation can be learned based on experiments or expert experience or machine learning algorithms, and then based on the current degree of sulfidation and the pulse frequency used in the current activation cycle, the adjustment pulse frequency of the next activation cycle is determined. For example: if the degree of sulfidation of the battery to be activated has been reduced a lot at the end of the current activation cycle, then the pulse frequency of charge and discharge can be appropriately reduced in the next activation cycle, so that the pulse frequency used for activation matches the degree of sulfidation of the battery to be activated, which can avoid battery damage or waste of resources due to too high a pulse frequency, or too low a pulse frequency reduces the battery activation efficiency and affects the battery activation effect.

[0040] In addition, the preset activation requirements can be set according to actual needs, such as: when the degree of vulcanization reaches a certain threshold, an activation operation is required. The specific requirements can be determined according to actual needs and are not specifically limited in the embodiments of this specification.

[0041] In some embodiments of this specification, the method for determining whether the sulfidation degree of the battery to be activated meets the preset activation requirements includes: If the change in the sulfidation degree of the battery to be activated is less than a preset threshold value during a preset number of consecutive activation cycles, it is determined that the sulfidation degree of the battery to be activated meets the preset activation requirement.

[0042] In a specific implementation process, when the sulfidation degree of the battery to be activated at the end of an activation cycle is obtained, the sulfidation degree can be compared with the sulfidation degree of the battery to be activated at the end of the previous preset number of activation cycles. If the change in the sulfidation degree of the battery to be activated is less than the preset threshold value for the consecutive preset number of activation cycles, it can be determined that the sulfidation degree of the battery to be activated meets the preset requirements. For example, if the change in the sulfidation degree of the battery to be activated is less than 0.5% for three consecutive activation cycles, it means that the effect of the battery activation operation is not obvious, and it is not necessary to continue the activation operation.

[0043] S110: performing constant current pulse charge and discharge of the battery to be activated in the next activation cycle according to the adjusted pulse frequency, and calculating a new round of sulfidation degree of the battery to be activated at the end of a new round of activation cycle. When the new round of sulfidation degree meets the preset activation requirement, calculating the adjusted pulse frequency of the next activation cycle charge and discharge, until the sulfidation degree of the battery to be activated meets the preset requirement, and stopping the activation operation of the battery to be activated.

[0044] In the specific implementation process, after determining the adjustment pulse frequency to be used in the next activation cycle, the battery to be activated is charged and discharged with constant current pulses in the next activation cycle according to the adjustment pulse frequency, and the process returns to step S102, and a new round of sulfidation degree of the battery to be activated at the end of the new activation cycle is recalculated, and based on the new round of sulfidation degree, it is determined whether the battery to be activated needs to continue the activation operation. When the activation operation is needed, the adjustment pulse frequency for the next activation cycle charge and discharge is calculated, and the next activation cycle charge and discharge is performed again based on the adjustment pulse frequency, until the sulfidation degree of the battery to be activated meets the preset activation requirements, and the activation operation of the battery to be activated is stopped.

[0045] The battery activation data processing method provided in the embodiments of the present specification performs constant current pulse charging and discharging on the battery to be activated, samples the voltage of the battery to be activated during the charging and discharging process, calculates the sulfidation degree of the battery to be activated based on the sampled voltage, and then adjusts the pulse frequency of charging and discharging in the next activation cycle based on the sulfidation degree, so that the pulse frequency of charging and discharging is adapted to the sulfidation degree of the battery, thereby avoiding battery damage or waste of resources due to too high a pulse frequency, or reducing the battery activation efficiency due to too low a pulse frequency, thereby affecting the battery activation effect, and improving the battery activation efficiency while ensuring that the battery is not damaged.

[0046] In some embodiments of this specification, the adjusting pulse frequency of charging and discharging in the next activation cycle is determined based on the current degree of sulfidation and the pulse frequency of charging and discharging in the current activation cycle, including: Obtaining the historical sulfidation degree of the battery to be activated at the end of the last activation cycle; Calculating the difference between the historical degree of vulcanization and the current degree of vulcanization to obtain a degree of vulcanization difference; The product of the difference between 1 and the difference in the degree of sulfidation and the pulse frequency during the current activation cycle charge and discharge is used as the adjusted pulse frequency during the next activation cycle charge and discharge.

[0047] In a specific implementation process, after obtaining the current sulfidation degree of the battery to be activated at the end of the current activation cycle, the historical sulfidation degree of the battery to be activated at the end of the previous activation cycle of the current activation cycle can be obtained. Then the difference between the historical sulfidation degree and the current sulfidation degree is calculated to obtain the sulfidation degree difference, and the adjustment pulse frequency for the activation operation of the battery to be activated in the next activation cycle is obtained based on the following formula: f(t)=f(t-1)×(1–(s(t-2)–s(t-1)) Wherein, t is the next activation cycle, t-1 is the current activation cycle, t-2 is the previous activation cycle, f(t-1) is the pulse frequency used to charge and discharge the battery to be activated in the current activation cycle, s(t-2) is the sulfation degree of the battery to be activated at the end of the previous activation cycle, and s(t-1) is the current sulfation degree.

[0048] The embodiments of this specification are based on the current sulfidation degree of the current activation cycle, combined with the historical sulfidation degree at the end of the previous activation cycle, to evaluate the activation effect of the battery to be activated in the current activation cycle, and then based on the pulse frequency used in the current activation cycle, adjust the pulse frequency of the next activation cycle, so that the pulse frequency used during activation is adapted to the sulfidation degree of the battery, thereby improving the efficiency and effect of battery activation.

[0049] In some embodiments of this specification, the method further includes: In the first and second activation cycles, the battery to be activated is subjected to constant current pulse charge and discharge using a preset pulse frequency.

[0050] In the specific implementation process, in the first and second activation cycles, a preset pulse frequency can be used to perform constant current pulse charging and discharging on the battery to be activated, wherein the specific value of the preset pulse frequency can be set according to actual needs, such as: it can be 1khz. Of course, according to actual needs such as: battery capacity, service life, etc., it can also be set to other values, which are not specifically limited in the embodiments of this specification.

[0051] In the first two activation cycles, the sulfide degree of the battery to be activated has not been calculated. At this time, the battery to be activated can be activated according to the preset pulse frequency, and the pulse frequency can be adjusted based on the sulfide degree of the battery to improve the efficiency of battery activation.

[0052] In some embodiments of this specification, the constant current pulse charging and discharging of the battery to be activated in the next activation cycle according to the adjusted pulse frequency includes: The charge and discharge pulse frequency is adjusted from the charge and discharge pulse frequency of the current activation cycle to the adjusted pulse frequency by using a ramp function, and the activated battery is subjected to constant current pulse charge and discharge in the next activation cycle.

[0053] In the specific implementation process, when the battery to be activated is activated in the next activation cycle, the embodiment of this specification uses a ramp function to gradually adjust the charge and discharge pulse frequency to the adjustment pulse frequency in the activation cycle. That is to say, in the next round of activation, the charge and discharge pulse frequency is not directly adjusted to the calculated adjustment pulse frequency, but the pulse frequency is gradually adjusted to the adjustment pulse frequency using a ramp function. Among them, the specific form of the ramp function can be selected according to actual needs, and the embodiment of this specification does not specifically limit this.

[0054] The effect of battery activation is lagging. In the embodiments of this specification, the pulse frequency is gradually adjusted through a ramp function to reduce the response speed so that the last result output can correspond to the current judgment conditions, so that the battery activation effect matches the response speed, and the activation operation is more adapted to the degree of battery sulfide, thereby improving the battery recovery efficiency and effect.

[0055] In some embodiments of the present specification, the step of adjusting the charge and discharge pulse frequency from the charge and discharge pulse frequency of the current activation cycle to the adjusted pulse frequency during the activation cycle by using a ramp function includes: According to the following formula, the charge and discharge pulse frequency is adjusted from the charge and discharge pulse frequency of the current activation cycle to the adjusted pulse frequency according to the preset adjustment cycle: f=f_last+(i / (T / t))(F-f_lst) Wherein, f is the pulse frequency of the next preset adjustment cycle, f_last is the pulse frequency of the current adjustment cycle, T is the activation cycle, t is the charging cycle of the battery to be activated during the current activation cycle, F is the adjustment pulse frequency, i is a positive integer greater than or equal to 0, and i is automatically increased by 1 each time the battery to be activated is charged.

[0056] In a specific implementation process, when the pulse frequency is gradually adjusted using a ramp function, the pulse frequency is adjusted once for each charge based on the charge and discharge frequency of the battery to be activated, and a variable adjustment coefficient is set. By multiplying the adjustment coefficient, the pulse frequency can be gradually adjusted to the required adjustment pulse frequency within the activation cycle. Specifically, according to the above formula, the charge and discharge pulse frequency can be adjusted to the adjustment pulse frequency within a new round of activation cycle.

[0057] For example: the activation cycle is 1 hour, and the pulse frequency used in the current activation cycle is 1kHZ, which is equivalent to charging once every 1ms. In this case, T=1 hour, t=1ms, and T / t=3600000. Using the above formula, the pulse frequency of the next activation cycle can be adjusted every 1ms, from 1kHZ to the calculated adjustment pulse frequency F within 1 hour, i starts from 0, and each time the pulse frequency i is adjusted, i is automatically increased by 1. Of course, after the current activation cycle ends, i is adjusted to 0.

[0058] The embodiments of this specification provide a method for gradually adjusting the pulse frequency during the activation cycle, so that the response speed of battery activation is adapted to the pulse frequency, thereby laying an accurate data foundation for subsequent adjustment of the pulse frequency and improving the efficiency and effect of battery activation.

[0059] Based on the battery activation data processing method described above, one or more embodiments of this specification also provide a terminal and a server for battery activation data processing. The terminal and the server may include a device (including a distributed system), software (application), module, component, server, terminal, etc. using the method described in the embodiment of this specification and a device combined with necessary implementation hardware. Based on the same innovative concept, the device in one or more embodiments provided in the embodiment of this specification is as described in the following embodiments.
