The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 is a schematic diagram of a power supply system of a lithium extraction tank according to some embodiments of the present disclosure.

The power supply system comprises a plurality of electrode plate pair groups, wherein each electrode plate pair group comprises at least one electrode plate pair. Therefore, it is considered that a plurality of electrode plate pairs are combined to form a lithium extraction tank, and the electrode plate pair group can be determined by taking a certain number of electrode plate pairs as a combination according to actual needs. In the prior art, the electrode plate pair group is typically powered by a power source to ensure that all electrode plate pairs within the electrode plate pair group are powered consistently. The external power supply obtains 12 volts after passing through the converter, and the 12 volts is converted into the working voltage (for example, 0.3 volts) of the lithium extraction tank and then is connected with a plurality of power supplies. Therefore, a plurality of power supplies of the lithium lifting groove are identical to each other, and the consistency of the power supplies is ensured.

In the industrialized production, the lithium extraction groove contains a large number of electrode plate pairs, if one electrode plate pair has faults, the prior lithium extraction process needs to disconnect the power supply of the electrode plate pair group where the fault electrode plate is located to isolate the fault electrode plate pair, so that other electrode plate pairs which work normally in the electrode plate pair group are also isolated, and the utilization rate of the electrode plate pairs and the lithium extraction efficiency are reduced.

For this reason, the power supply system of lithium extraction groove of this application includes a plurality of first power, a plurality of first circuit breakers that correspond the setting of a plurality of power, and the first controller of being connected with a plurality of first circuit breakers. Wherein, a plurality of first power supplies are used for supplying power to the group for the electrode plate that the lithium extraction groove contains. The above-mentioned lithium extraction groove of this application is including a plurality of electrode plate pair group that arrange in proper order, and above-mentioned electrode plate pair group contains at least one electrode plate pair, and above-mentioned electrode plate pair contains positive electrode plate and negative electrode plate, and the both sides coating of above-mentioned positive electrode plate has and is the embedded lithium state material, and the both sides coating of above-mentioned negative electrode plate has and is the underlithium state material, and above-mentioned positive electrode plate and negative electrode plate are arranged in turn in the above-mentioned lithium extraction groove. The positive electrode of the first power supply is connected with the positive electrode plate in the corresponding electrode plate pair group, and the negative electrode of the first power supply is connected with the negative electrode plate in the corresponding electrode plate pair group. In this way, the consistency of the power supply of the electrode plate pairs within the electrode plate pair group can be ensured. And a plurality of first circuit breakers, each first circuit breaker is respectively connected with the first controller and the corresponding first power supply and used for closing or opening the connection between the corresponding first power supply and the electrode plate pair group. And the first controller is respectively connected with the plurality of first circuit breakers and used for controlling the first circuit breakers to be closed or opened.

According to the power supply system of the lithium extraction groove, the first power supply is used for supplying power to the electrode plate pair group, the first controller is used for controlling the first circuit breaker to be closed or opened, and then the first power supply is controlled to supply power to the electrode plate pair group, so that the state control of the electrode plate pair lithium extraction can be improved, and the lithium extraction efficiency is improved. The first controller can also send out an alarm signal when the first circuit breaker is in an open state or the electrode plate pair fails, but the first circuit breaker is in a closed state, and a technician can determine the corresponding failed electrode plate according to the alarm signal and perform corresponding operation.

Fig. 1 is a block diagram of a power supply system in which an electrode plate pair group includes only one electrode plate pair. As shown in fig. 1, each electrode plate pair group contains only one electrode plate pair, the positive electrode plate of the first electrode plate pair being labeled "1+", the negative electrode plate being labeled "1-". The positive electrode and the negative electrode of the first power supply DC (1) are respectively connected with the positive electrode plate and the negative electrode plate of one electrode plate pair to supply power to the electrode plate pair. The positive electrode plate is coated on both sides with a material in a lithium intercalation state (indicated by dense dots) and the negative electrode plate is coated on both sides with a material in an under-lithium state (indicated by cross-hatching). The positive electrode plate is arranged in the anode side tank body for containing the lithium-rich liquid, the negative electrode plate is arranged in the cathode side tank body for containing the lithium liquid to be extracted, and the anode side tank body and the cathode side tank body are separated by an anion membrane. The first circuit breaker Q (1) may be disposed between the first power source DC (1) and the positive electrode plate or the negative electrode plate. When the electrode plates need to be powered off due to faults, the first controller W can control the first circuit breaker Q (1) to cut off the connection between the first power supply DC (1) and the electrode plate pairs. Similarly, fig. 1 also includes the positive electrode plate of the second electrode plate pair labeled "2+", the negative electrode plate labeled "2-", etc., up to the nth electrode plate pair. Correspondingly, the system also comprises a first power supply DC (2), a first power supply DC (3), a first power supply DC (n); a first circuit breaker Q (2) first circuit breaker Q (3) · first circuit breaker Q (n). It should be noted that, in order to illustrate the functions of the respective components, the first power supply and the first circuit breaker are described herein as two separate devices. In practice, the first power source and the corresponding first circuit breaker may also be implemented by one device, depending on the actual need.

Fig. 2 is a block diagram of a power supply system in which the electrode plate pair group includes two (in the case where a plurality of electrode plate pairs can be inferred) electrode plate pairs. As shown in fig. 2, the electrode plate pair group includes two electrode plate pairs connected in the same polarity, and thus, the power supply uniformity of the plurality of electrode plate pairs in the same electrode plate pair group is ensured by the first power supply DC 1. In practice, the first power supplies DC (1), DC (2) and DC (3) and DC (n) are also connected in a common-negative and common-positive mode, so that the power supply consistency of all electrode plate pairs in the whole lithium extraction groove is ensured.

In general, when the first power supply DC (1) supplies power to the electrode plate pair, the positive electrode plate and the negative electrode plate in the same electrode plate pair are affected by an electric field, and the lithium-intercalation material and the lithium-deficient material which are close to one side of the first power supply DC (1) are located in the electric field formed by the positive electrode plate and the negative electrode plate, and the lithium-intercalation material and the lithium-deficient material which are far away from one side of the first power supply DC (1) are located outside the electric field formed by the positive electrode plate and the negative electrode plate. Therefore, the degree of reaction of the lithium-intercalated and lithium-deficient materials on the side closer to the first power supply DC (1) is stronger than the reaction strength of the lithium-intercalated and lithium-deficient materials on the side farther from the first power supply DC (1).

For example, lithium ions in the lithium-intercalated material on the side close to the first power supply DC (1) can directly enter the lithium-rich liquid, and lithium ions in the lithium-rich liquid to be extracted can directly enter the lithium-deficient material on the side close to the first power supply DC (1). The lithium-intercalated material and the lithium-deficient material on the side far away from the first power supply DC (1) react with the lithium-rich liquid and the lithium liquid to be extracted respectively, and are weaker than the lithium-intercalated material and the lithium-deficient material on the side near to the first power supply DC (1) react with the lithium-rich liquid and the lithium liquid to be extracted respectively.

Therefore, in fig. 1 and 2, the electrode plate is not efficient in extracting lithium to a different extent. For this purpose, the above power supply system of the present application may further include: and the second power supplies are arranged between the two adjacent first power supplies and are connected with the first adjacent power supplies in a common positive mode and the second adjacent power supplies in the two adjacent first power supplies in a common negative mode. The second power supply may be configured to supply power to an adjacent positive electrode plate and an adjacent negative electrode plate between two adjacent electrode plate pairs, wherein the adjacent positive electrode plate is a positive electrode plate of a first electrode plate pair of the two adjacent electrode plate pairs, and the adjacent negative electrode plate is a negative electrode plate of a second electrode plate pair of the two adjacent electrode plate pairs.

Therefore, a second power supply is added between two adjacent first power supplies, so that the adjacent positive electrode plates and negative electrode plates in the pair of two electrode plates can be used for extracting lithium under the action of the corresponding first power supplies DC (1), lithium can be further extracted under the action of the second power supplies, and the lithium extraction efficiency is improved. When the electrode plate fails (e.g., is in a lithium intercalation state or is in a non-uniform state, falls off, etc.) on a certain electrode plate, the first circuit breaker in fig. 1 and 2 can be used for performing corresponding operation on the failed electrode, for example, breaking, etc.

Fig. 3 is a block diagram of a power supply system in which a second power supply is added to the power supply of fig. 1. In fig. 3, a first power supply DC (1) and a first power supply DC (2) supply power to a first electrode plate pair and a second electrode plate pair, respectively. The positive electrode plate of the first electrode plate pair comprises two faces L11 and L12, and the negative electrode plate comprises two faces L13 and L14. The positive electrode plate of the second electrode plate pair comprises two faces L21 and L22, and the negative electrode plate comprises two faces L23 and L24. When the first power supply DC (1) supplies power to the first electrode plate pair, since the L12 and the L13 are positioned in an electric field between the positive electrode plate and the negative electrode plate of the first electrode plate pair, the lithium extraction reaction intensity between the L12 and the L13 and the lithium-rich liquid and the lithium liquid to be extracted is larger than the lithium extraction reaction intensity between the L11 and the L14 and the lithium-rich liquid and the lithium liquid to be extracted. Therefore, L12 and L13 have higher lithium extraction efficiency than L11 and L14. In order to further improve lithium extraction efficiency, the second power supply DC (12) is added between two electrode plate pairs, so that L14 (namely adjacent negative electrode plates) and L21 (namely adjacent positive electrode plates) are also positioned in an electric field, and the electric field intensity between L14 (namely adjacent negative electrode plates) and L21 (namely adjacent positive electrode plates) is improved. Wherein "12" in DC (12) represents a second power supply added between the first power supply DC (1) (i.e., "1" in "12") and the first power supply DC (2) (i.e., "2" in "12"). Because the negative electrode plate where L14 is connected with the negative electrode of the first power supply DC (1), the positive electrode plate where L21 is connected with the positive electrode of the first power supply DC (2), the negative electrode of the second power supply DC (12) is connected with the negative electrode plate where L14 is located, and the positive electrode of the second power supply DC (12) is connected with the positive electrode plate where L21 is located. In this way, the second power supply DC (12) forms a common-negative and common-positive wiring mode with the first power supply DC (1) and the first power supply DC (2) respectively. Similarly, there may be other secondary power sources DC (23), etc.

Fig. 4 is a block diagram of a power supply system in which a second power supply is added to the power supply of fig. 2. Since the electrode plate pair group in fig. 4 includes two electrode plate pairs, the added second power supply DC (12) can only enhance the electric field strength between L24 and L31, and L14 and L21 to be the same as that in fig. 2.

When the electrode plate fails to a certain electrode plate, the consistency of the lithium extraction groove is poor. For this purpose, the second power supply is also provided with a corresponding second circuit breaker, as Q (12) in fig. 3 and 4. The second circuit breaker is respectively connected with the first controller and the corresponding second power supply and is used for closing or opening the connection between the corresponding second power supply and the adjacent positive electrode plate and the adjacent negative electrode plate.

The power supply system of the application can further comprise a second controller which is respectively connected with the positive electrode plate and the negative electrode plate in the lithium extraction groove and used for detecting a first voltage signal on the positive electrode plate and a second voltage signal on the negative electrode plate and determining consistency information of the lithium extraction groove according to the first voltage signal and the second voltage signal, wherein the consistency information is used for representing consistency of lithium extraction states of a plurality of electrode plate pairs in the lithium extraction groove, and the consistency information is normal or abnormal. The second controller may first detect the first operating state information of each electrode plate pair, then determine the second operating state information of the lithium extraction groove according to the first operating state information of the plurality of electrode plate pairs, and finally determine the consistency of the lithium extraction groove according to the second operating state information. The first controller may be configured to determine at least one fault electrode plate pair and control at least one target circuit breaker corresponding to the at least one fault electrode plate pair to be opened in response to receiving the consistency information of the second controller as an abnormality. FIG. 5 is a block diagram of a power supply system with a second controller added to the system of FIG. 3; fig. 6 is a block diagram of a power supply system in which a second controller is added to the system of fig. 4.

With continued reference to fig. 7, fig. 7 illustrates a flow 700 of some embodiments of a lithium extraction control method of a lithium extraction tank according to the present disclosure. The lithium extraction control method of the lithium extraction groove comprises the following steps:

and step 701, determining at least one fault electrode plate pair of the lithium extraction groove in response to the consistency information of the lithium extraction groove as an abnormality.

In some embodiments, an execution body (e.g., the first controller W in fig. 1-6) of the lithium extraction control method of the lithium extraction tank is connected with the first circuit breaker and the second circuit breaker in fig. 1-6, and the first circuit breaker and the second circuit breaker can be controlled to be closed or opened. When the consistency information of the lithium extraction groove sent by the second controller is normal, the electrode plate pairs in the lithium extraction groove are indicated to work normally, and the execution main body can keep the closed state of the first circuit breaker and the second circuit breaker. When the consistency information of the lithium extraction groove sent by the second controller is abnormal, the fact that the fault electrode plate pairs exist in the lithium extraction groove is indicated, and the execution main body needs to determine which electrode plate pairs in the lithium extraction groove are the fault electrode plate pairs.

At step 702, at least one power source to be processed corresponding to the at least one faulty electrode plate pair is determined.

When a faulty electrode plate pair is determined, the execution body may further determine at least one power supply to be processed corresponding to the faulty electrode plate pair. The power to be processed can be a first power source, or can be a first power source and a second power source, which are determined specifically according to the corresponding power supply system structure diagram.

And step 703, inquiring the wiring information of the at least one power supply to be processed, and isolating the at least one fault electrode plate pair based on the wiring information.

When the lithium extraction process needs to be adjusted and the electrode plate peer-to-peer operation needs to be replaced, the execution main body can isolate the fault electrode plate pair through the wiring information of the power supply to be processed and send out an alarm signal. Thereafter, replacement, repair, etc. operations may be performed on the faulty electrode plate pair.

According to the lithium extraction control method, based on the power supply system of the lithium extraction groove, when the consistency information of the lithium extraction groove is abnormal, the fault electrode plate pair is determined, the corresponding power supply to be processed is determined, and then the operations such as isolation of the fault electrode plate pair are realized, so that the safety of the lithium extraction process is improved.

With continued reference to fig. 8, fig. 8 illustrates a flow 800 of some embodiments of a lithium extraction control method of a lithium extraction tank according to the present disclosure. The lithium extraction control method of the lithium extraction groove comprises the following steps:

step 801, determining at least one fault electrode plate pair identifier according to the electrode plate pair working state information with abnormal state information in response to the consistency information of the lithium extraction groove being abnormal.

The consistency information of the lithium ion battery cell comprises electrode plate pair working state information. The electrode plate pair working state information is used for representing the working state of each corresponding electrode plate pair, and can comprise an electrode plate pair identifier and state information, wherein the electrode plate pair identifier is used for marking the electrode plate pair, and the electrode plate pair identifier can be a number, a character or a combination of the number and the character, and the like, and is specifically determined according to actual needs. The above state information includes normal or abnormal. When a faulty electrode plate pair exists in the lithium extraction tank, the execution body (e.g., the first controller W in fig. 1-6) may determine that the state information is at least one faulty electrode plate pair identification of an abnormality.

At step 802, at least one faulty electrode plate pair is determined by the at least one faulty electrode plate pair identification.

After determining the fault electrode plate pair identifier, the execution body may determine at least one fault electrode plate pair through the fault electrode plate pair identifier.

In some optional implementations of some embodiments, the determining at least one fault electrode plate pair by the at least one fault electrode plate pair identifier may include the steps of:

in a first step, at least one current information corresponding to the at least one fault electrode plate pair identifier is acquired in response to each of a plurality of electrode plate pair groups including one electrode plate pair.

In the lithium extraction process, the current information of the fault electrode plate pair is different from the current information of the electrode plate pair which works normally due to the fact that the electrode plate is in a lithium intercalation state material or in a lithium shortage state material is uneven, falls and the like. For this purpose, the execution body may first acquire current information corresponding to each faulty electrode plate pair identification.

And a second step of determining the at least one faulty electrode plate pair based on the at least one current information.

The execution body may compare the current information to determine a faulty electrode plate pair.

In some optional implementations of some embodiments, the obtaining at least one current information corresponding to the at least one fault electrode plate pair identifier may include: and determining an initial power supply corresponding to the fault electrode plate pair identifier in the at least one fault electrode plate pair identifier, and acquiring current information of the initial power supply.

As is apparent from the above description, the electrode plates are supplied with power from the corresponding power sources. The executing body can determine an initial power supply for supplying power to the fault electrode plate pair through the fault electrode plate pair identifier, and then acquire current information of the initial power supply, wherein the current information is the current information of the fault electrode plate pair.

In some optional implementations of some embodiments, the determining the initial power supply corresponding to the fault electrode plate pair identifier may include the following steps:

and a first step of marking the first power supply as an initial power supply in response to the connection of the fault electrode plate pair corresponding to the fault electrode plate pair identification with the first power supply.

When the electrode plate pair is powered by only the first power source, the first power source corresponding to the failed electrode plate pair may be marked as an initial power source.

And a second step of respectively marking the first power supply and the two adjacent second power supplies as initial power supplies in response to the connection of the fault electrode plate pair corresponding to the fault electrode plate pair identification with the first power supply and the two adjacent second power supplies connected with the first power supply.

When the electrode plate pair is powered by the first power supply and the second power supply simultaneously, the positive electrode plate and the negative electrode plate of the electrode plate pair are also powered by the corresponding second power supply. Thus, the execution subject may mark the first power source and the two adjacent second power sources as initial power sources, respectively, taking into consideration the current information of the first power source and the corresponding two adjacent second power sources in combination.

In some optional implementations of some embodiments, determining the at least one fault electrode plate pair based on the at least one current information may include: determining the at least one fault electrode plate pair through current information of the first power supply and two adjacent second power supplies in response to the initial power supply corresponding to the first power supply and the two adjacent second power supplies; otherwise, determining the at least one fault electrode plate pair by the first power supply.

When the initial power source includes a first power source and two adjacent second power sources (corresponding to the case where fig. 3, 4, 5 and 6 include the first power source and the second power source), the fault electrode plate can be further judged by the currents of the two adjacent second power sources. Therefore, the execution body needs to comprehensively judge the fault electrode plate pair by the current information of the first power supply and the current information of each of the two adjacent second power supplies. Otherwise, when the initial power source has only one first power source (corresponding to the case where fig. 1 and 2 contain only the first power source), the fault electrode plate pair may be directly determined from the current information passing through the first power source.

The electrode plate pair includes a positive electrode plate and a negative electrode plate each having two faces, each of which is likely to be in a failure condition. The second electrode plate pair (consisting of "2+" and "2-" in fig. 3) is taken as an example of a faulty electrode plate, and analysis is performed separately.

In some optional implementations of some embodiments, determining the at least one fault electrode plate pair from current information of the first power source and two adjacent second power sources may include:

and a first step of respectively inquiring the first slave current information and the second slave current information of the two adjacent second power supplies in response to the fact that the master current information of the first power supply is smaller than a first current threshold value.

In practice, the current of a failed electrode plate pair is typically less than a properly functioning electrode plate pair. When the main current information of the first power supply is smaller than the first current threshold value, the fault electrode plate pair is indicated, and one inner side face of one electrode plate fails. The current information of the first power supply is set as master current information, and the current information of the second power supply is set as slave current information. The first current threshold is a current value corresponding to the occurrence of a fault on one inner side surface of the fault electrode plate pair. Taking fig. 3 as an example, in the second electrode plate pair, L22 and L23 may be considered as the inner side surfaces of the second electrode plate pair, and L21 and L24 may be considered as the outer side surfaces of the second electrode plate pair, and the same applies to the other electrode plate pairs. At this time, the execution body cannot yet determine which of L22 and L23 has failed. Therefore, the execution subject needs to further query the first slave current information and the second slave current information of two adjacent second power sources. The "inner side" and the "outer side" are relatively speaking, and for example, L21 in fig. 3 is the "inner side" with respect to the second power supply DC (12), and is the "outer side" with respect to the 1 st power supply DC (2).

And a second step of determining that an electrode plate of the fault electrode plate pair, which is connected with the first power supply and the second power supply corresponding to the first slave current information, is a fault electrode plate in response to the first slave current information being smaller than the second current threshold, and one side of the fault electrode plate, which is close to the first power supply, is a fault surface. Two adjacent second power sources are provided on the left and right sides of the fault electrode plate pair, such as the second power source DC (12) and the second power source DC (23) in fig. 3. When the first slave current information of the second power supply DC (12) is smaller than the second current threshold value, one outer side surface of L13, L14, L21 and L22 corresponding to the second power supply DC (12) is indicated to have faults. The second current threshold is a current value corresponding to the occurrence of a fault on one outer side surface in the fault electrode plate pair. The second power supply DC (12) has two outer sides L13 and L22, and assuming that there is no fault plane among L11, L12, L13, and L14, the fault plane is L22 as a comprehensive consideration. That is, the electrode plate of the second electrode plate pair, which is connected to the first power source and the second power source corresponding to the first slave current information, is a faulty electrode plate, and the side of the faulty electrode plate, which is close to the first power source, is a faulty surface. Similarly, when the second slave current information of the second power supply DC (23) is smaller than the second current threshold, the corresponding fault plane is L23.

and in the first step, the first slave current information and the second slave current information of the two adjacent second power supplies are respectively inquired in response to the fact that the master current information of the first power supply is smaller than a second current threshold value.

When the main current information of the first power supply is smaller than the second current threshold value, it is indicated that one of the faces L21 and L24 in fig. 3 fails. But it is not yet possible to determine whether it is L21 or L24. The execution body may further query the first slave current information and the second slave current information of the two adjacent second power sources.

And a second step of determining that an electrode plate of the fault electrode plate pair, which is connected with the second power supply corresponding to the first power supply and the first slave current information respectively, is a fault electrode plate in response to the first slave current information being smaller than the first current threshold, and one side of the fault electrode plate, which is far away from the first power supply, is a fault surface.

Similar to the above process, when the first slave current information is smaller than the first current threshold, it is indicated that a fault occurs on one inner side surface in the electrode plate corresponding to the second power supply. Such as L14 or L21 in the second power supply DC (12) in fig. 3. Since L14 belongs to the first electrode plate pair, and assuming that the first electrode plate pair does not fail, L21 is the failure plane. That is, the electrode plate of the fault electrode plate pair, which is connected to the first power source and the second power source corresponding to the first slave current information, is the fault electrode plate, and the side of the fault electrode plate, which is away from the first power source, is the fault surface.

In some optional implementations of some embodiments, the determining the at least one fault electrode plate pair from current information of the first power source and two adjacent second power sources includes: and determining that two electrode plates contained in the fault electrode plate pair are fault electrode plates and one side, close to the first power supply, of the two fault electrode plates is a fault surface in response to the fact that the main current information of the first power supply is smaller than a third current threshold.

And when the main current information of the first power supply is smaller than the third current threshold value, indicating that the fault electrode plate pair has two inner side faces to generate faults. At this time, the execution body may determine that the two electrode plates included in the faulty electrode plate pair are faulty electrode plates, and one side of the two faulty electrode plates, which is close to the first power supply, is a faulty surface (e.g., L22 and L23 in fig. 3). The third current threshold is a current value corresponding to the occurrence of faults on two inner side surfaces in the fault electrode plate pair.

In some optional implementations of some embodiments, determining the at least one fault electrode plate pair from current information of the first power source and two adjacent second power sources may include: and determining that two electrode plates contained in the fault electrode plate pair are fault electrode plates and one sides, far from the first power supply, of the two fault electrode plates are fault surfaces in response to the fact that the main current information of the first power supply is smaller than a fourth current threshold.

And when the main current information of the first power supply is smaller than the fourth current threshold value, indicating that two outer side surfaces of the fault electrode plate pair have faults. At this time, the execution body may directly determine that the two electrode plates included in the faulty electrode plate pair are faulty electrode plates, and a side of the two faulty electrode plates away from the first power supply is a faulty surface (e.g., L21 and L24 in fig. 3). The fourth current threshold is a current value corresponding to the occurrence of faults on two outer side surfaces in the fault electrode plate pair.

and a first step of respectively inquiring the first slave current information and the second slave current information of the two adjacent second power supplies in response to the fact that the master current information of the first power supply is smaller than a fifth current threshold value.

When the primary current information of the first power supply is less than the fifth current threshold, it is indicated that the faulty electrode plate pair has one inner side and one outer side faulty, and that the two faulty sides are not on the same electrode plate. The execution body needs to further analyze which of the positive electrode plate and the negative electrode plate has failed. Therefore, the execution subject needs to acquire the first slave current information and the second slave current information of two adjacent second power supplies. The fifth current threshold is a current value corresponding to when one inner side surface and one outer side surface of the fault electrode plate pair have faults and the inner side surface and the outer side surface of the faults are not on the same electrode plate.

A second step of determining, in response to the first slave current information being smaller than the second current threshold, that an electrode plate of the pair of fault electrode plates, which is connected to the second power supply corresponding to the first power supply and the first slave current information, is a fault electrode plate, and that a side of the fault electrode plate, which is close to the first power supply, is a fault surface; the electrode plates of the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the second slave current information, are fault electrode plates, and one side of the fault electrode plates, which is far away from the first power supply, is a fault surface.

And when the first slave current information is smaller than the second current threshold value, indicating that the outer side surface of one electrode plate in the electrode plate pair connected by the second power supply corresponding to the first slave current information has faults. Since there is a failure of one inner side and one outer side at this time and the two sides are not on the same electrode plate, after one failure side is determined, the other failure side can be determined. Taking fig. 3 as an example, when the first slave current information corresponding to the second power supply DC (12) is smaller than the second current threshold, the executing body may determine that the fault plane is L22, and the other fault plane is L24. That is, the execution body may determine that an electrode plate of the pair of fault electrode plates, which is connected to the first power source and the second power source corresponding to the first slave current information, is a fault electrode plate, and a side of the fault electrode plate, which is close to the first power source, is a fault surface (L22); the electrode plates of the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the second slave current information, are fault electrode plates, and one side of the fault electrode plates, which is far away from the first power supply, is a fault surface (L24).

and a first step of respectively inquiring the first slave current information and the second slave current information of the two adjacent second power supplies in response to the fact that the master current information of the first power supply is smaller than a sixth current threshold value.

When the main current information of the first power supply is smaller than the sixth current threshold value, the fault electrode plate pair has one inner side surface and one outer side surface fault, and the two fault surfaces are on the same electrode plate. Therefore, the execution subject needs to acquire the first slave current information and the second slave current information of two adjacent second power supplies. The sixth current threshold is a current value corresponding to a fault electrode plate pair, wherein the fault electrode plate pair has an inner side surface and an outer side surface, and the inner side surface and the outer side surface of the fault are on the same electrode plate.

And a second step of determining that the electrode plates in the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the first slave current information, are fault electrode plates in response to the first slave current information being smaller than the sixth current threshold, wherein both sides of the fault electrode plates are fault surfaces.

When the first slave current information is also smaller than the sixth current threshold, it is indicated that, in the second power supply corresponding to the first slave current information, both sides of one electrode plate are faulty (e.g., L21 and L22 in fig. 3). At this time, the execution body may determine that the electrode plate of the pair of fault electrode plates, which is connected to the first power source and the second power source corresponding to the first slave current information, is a fault electrode plate, and both sides of the fault electrode plate are fault surfaces. Similarly, when the first slave current information is normal and the second slave current information is smaller than the sixth current threshold, the fault plane is L23 and L24.

and a first step of respectively inquiring the first slave current information and the second slave current information of the two adjacent second power supplies in response to the fact that the master current information of the first power supply is smaller than a seventh current threshold value.

When the main current information of the first power supply is smaller than the seventh current threshold value, the fault electrode plate pair is indicated that three sides have faults. Therefore, the execution subject needs to acquire the first slave current information and the second slave current information of two adjacent second power supplies. The seventh current threshold is a current value corresponding to the case that three sides of the fault electrode plate pair have faults and two inner sides of the fault electrode plate pair have faults.

A second step of determining that an electrode plate in the pair of fault electrode plates, which is connected with the first power supply and the second power supply corresponding to the first slave current information, is a first fault electrode plate and both sides of the first fault electrode plate are fault surfaces in response to the first slave current information being smaller than a sixth current threshold; and determining that the electrode plates in the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the second slave current information, are second fault electrode plates, and the side, close to the first power supply, of the second fault electrode plates is a fault surface.

When the first slave current information is smaller than the sixth current threshold, it is indicated that, in the second power supply corresponding to the first slave current information, both sides of one electrode plate are faulty (e.g., L21 and L22 in fig. 3). The inner side face L23 of the other electrode plate of the first power supply DC (2) is also a fault face. That is, the electrode plates of the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the first slave current information, are first fault electrode plates, and both sides of the first fault electrode plates are fault surfaces; and determining that the electrode plates in the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the second slave current information, are second fault electrode plates, and the side, close to the first power supply, of the second fault electrode plates is a fault surface.

and a first step of respectively inquiring the first slave current information and the second slave current information of the two adjacent second power supplies in response to the fact that the master current information of the first power supply is smaller than an eighth current threshold value.

When the main current information of the first power supply is smaller than the eighth current threshold value, the fault electrode plate pair is indicated that three sides have faults. Therefore, the execution subject needs to acquire the first slave current information and the second slave current information of two adjacent second power supplies. The eighth current threshold is a current value corresponding to the fault electrode plate pair when three sides have faults and two outer sides have faults.

A second step of determining that an electrode plate in the pair of fault electrode plates, which is connected with the first power supply and a second power supply corresponding to the first slave current information, is a first fault electrode plate and both sides of the first fault electrode plate are fault surfaces in response to the first slave current information being smaller than a sixth current threshold; and determining that the electrode plates in the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the second slave current information, are second fault electrode plates, and the side, away from the first power supply, of the second fault electrode plates is a fault surface.

When the first slave current information is smaller than the sixth current threshold, it is indicated that, in the second power supply corresponding to the first slave current information, both sides of one electrode plate are faulty (e.g., L21 and L22 in fig. 3). The outer side face L24 of the other electrode plate of the first power supply DC (2) is also a fault face. That is, the electrode plates of the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the first slave current information, are first fault electrode plates, and both sides of the first fault electrode plates are fault surfaces; and determining that the electrode plates in the fault electrode plate pair, which are respectively connected with the first power supply and the second power supply corresponding to the second slave current information, are second fault electrode plates, and the side, away from the first power supply, of the second fault electrode plates is a fault surface.

In some optional implementations of some embodiments, determining the at least one fault electrode plate pair from current information of the first power source and two adjacent second power sources may include: and determining that two electrode plates in the fault electrode plate pair are fault electrode plates and two sides of each fault electrode plate are fault surfaces in response to the main current information of the first power supply being smaller than a ninth current threshold.

When the main current information of the first power supply is smaller than the ninth current threshold value, the four faces of the fault electrode plate pair are indicated to be faulty.

The magnitude of each threshold described above is measured according to the electrode plate. The first current threshold value to the ninth current threshold value are successively decreased. For simplicity of description, the above complete description of "the main current information of the first power supply is smaller than the first current threshold" is "the main current information of the first power supply is smaller than the first current threshold and larger than the second current threshold", and the same can infer other situations, which are not described in detail herein.

After determining the fault surface of the electrode plate, the executing body can send out an alarm signal.

Step 803, determining at least one power source to be processed corresponding to the at least one faulty electrode plate pair.

The content of step 803 is the same as that of step 702, and will not be described in detail here.

Step 804, inquiring the wiring information of the at least one power source to be processed, and isolating the at least one fault electrode plate pair based on the wiring information.

In some optional implementations of some embodiments, isolating the at least one fault electrode plate pair based on the wiring information may include:

And a first step of determining at least one target breaker corresponding to the at least one power supply to be processed through the wiring information.

The above-described wiring information of the present application can be used to characterize the connection relationship of the power source to the electrode plate pair, i.e., which power source supplies power to which electrode plate pair. Then, the execution body can determine the target circuit breaker corresponding to the power supply to be processed through the wiring information.

And secondly, isolating the at least one fault electrode plate pair through the power supply state information of the at least one target circuit breaker and the lithium extraction groove.

The lithium lifting groove can have various working states, and the power supply characteristics of the lithium lifting groove are different under different working states. Therefore, the execution body needs to isolate the fault electrode plate pair through the power supply state information of the target circuit breaker and the lithium extraction groove, so as to reduce other factors affecting safety, such as arc and the like, occurring when isolating the fault electrode plate pair as much as possible.

In some optional implementations of some embodiments, the isolating the at least one fault electrode plate pair by the power supply status information of the at least one target circuit breaker and the lithium extraction tank may include:

and firstly, acquiring the power supply state information of the lithium extraction groove.

The execution body may first acquire power supply state information of the lithium extraction tank. Wherein, the power supply status information may include any one of the following: constant current power supply, constant voltage power supply and multi-constant current section power supply.

And a second step of isolating the at least one faulty electrode plate pair based on the at least one target circuit breaker and the power supply status information.

The execution body can select a proper mode to isolate the fault electrode plate pair according to the power supply state information of the target circuit breaker and the lithium extraction groove.

In some optional implementations of some embodiments, isolating the at least one fault electrode plate pair based on the at least one target circuit breaker and the power status information may include: and responding to the power supply state information to supply power for the constant current, and isolating the at least one fault electrode plate pair through the at least one target circuit breaker after reducing the current of the constant current power supply of the at least one fault electrode plate pair to the set current.

When the power supply state information of the lithium extraction groove is constant current power supply, the execution main body can firstly reduce the current of the constant current power supply of the fault electrode plate pair to a set current, and then isolate the at least one fault electrode plate pair through the at least one target circuit breaker.

In some optional implementations of some embodiments, isolating the at least one fault electrode plate pair based on the at least one target circuit breaker and the power status information may include: and responding to the power supply state information to supply power to the constant voltage, and isolating the at least one fault electrode plate pair through the at least one target circuit breaker after reducing the voltage of the constant voltage power supply of the at least one fault electrode plate pair to a set voltage.

When the power supply state information of the lithium-providing tank is constant voltage power supply, the execution body may reduce the voltage of the constant voltage power supply of the at least one fault electrode plate pair to a set voltage and then isolate the at least one fault electrode plate pair through the at least one target circuit breaker.

In some optional implementations of some embodiments, isolating the at least one fault electrode plate pair based on the at least one target circuit breaker and the power status information may include: responding to the power supply state information to supply power to the multiple constant current sections, and isolating the at least one fault electrode plate pair through the at least one target circuit breaker after reducing the current of the at least one fault electrode plate pair to the set current when the current of the current constant current section power supply of the multiple constant current sections power supply is larger than the set current; otherwise, isolating the at least one faulty electrode plate pair directly by the at least one target circuit breaker.

When the power supply state information of the lithium extraction groove is multi-constant current section power supply, the constant current is reduced from high to low in sequence. If the current supplied by the current constant current section is larger than the set current, the current value of the current constant current is larger, and the factors which influence safety, such as electric arcs, can be generated by direct isolation. At this time, the execution body may isolate the at least one fault electrode plate pair by the at least one target circuit breaker after reducing the current of the at least one fault electrode plate pair to a set current; otherwise, the current supplied by the current constant current section is smaller than or equal to the set current, which means that the current value of the current constant current is small enough, and the current constant current is directly isolated without generating factors such as electric arcs which affect safety. The execution body may isolate the at least one faulty electrode plate pair directly through the at least one target circuit breaker.
