[0002] Based on the advantage of batteries being recyclable, their application scenarios have been extended to multiple fields, such as power batteries used in new energy vehicles, providing a key impetus for people to achieve cleaner and lower-carbon travel.
[0003] However, whether it's a power battery or a battery used in other fields, the phenomenon of float charging is common during the charging process. This means that if a battery is connected to a charging device before it's fully charged, it will begin charging. Similarly, after the battery is fully charged, it enters a power-draining phase. If this drained battery is then connected to a charging device, it will also begin charging. However, in practice, it has been found that if a battery repeatedly enters the charging phase after being fully charged with low power consumption, it can damage the battery under high current, thus reducing its lifespan.
[0004] Therefore, it is particularly important to reduce the occurrence of battery float charging in order to solve the problem of reduced battery life caused by battery float charging. Summary of the Invention

[0094] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0095] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or end that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or ends.
[0096] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0097] This invention discloses a battery anti-float charging control method and device. After the battery meets the full charge condition, it determines whether the battery meets the triggering conditions for an anti-float charging strategy based on the collected real-time power information. When the determination result is yes, the corresponding target anti-float charging strategy is determined and executed based on the battery's attribute information. This improves the accuracy of determining the target anti-float charging strategy, reduces the occurrence of battery float charging, and solves the problem of reduced battery life caused by battery float charging. Detailed descriptions follow.
[0098] Example 1
[0099] Please see Figure 1 , Figure 1 This is a schematic flowchart of a battery anti-float charging control method disclosed in an embodiment of the present invention. Figure 1The described battery anti-float charging control method can be applied to a battery management system / platform, which can be deployed locally on the battery user or in a cloud / edge platform corresponding to the battery user. The battery user includes, but is not limited to, vehicles, mobile phones, tablets, computers, servers, urban energy storage lighting equipment, etc., and can also be applied to the battery itself / various charging devices corresponding to the battery. This invention does not limit the scope of the application. Figure 1 As shown, the battery anti-float charging control method may include the following operations:
[0100] 101. Once the battery is fully charged, collect the real-time battery power information.
[0101] In this embodiment of the invention, the real-time power information mentioned above includes real-time state of charge information.
[0102] 102. Based on real-time power information, determine whether the battery meets the trigger conditions for the anti-float charging strategy.
[0103] In this embodiment of the invention, the anti-float charging strategy triggering condition includes a necessary triggering sub-condition, which indicates that the battery is connected to the charging device.
[0104] In this embodiment of the invention, optionally, the above-mentioned determination of whether the battery meets the anti-float charging strategy triggering conditions based on real-time power information may include the following operations:
[0105] Determine whether the battery is connected to a charging device. If the battery is connected to a charging device, determine whether the real-time power information is greater than or equal to a preset power threshold. If the real-time power information is greater than or equal to the preset power threshold, determine that the battery meets the triggering conditions of the anti-float charging strategy.
[0106] Specifically, when it is determined that the battery is not connected to a charging device and / or when it is determined that the real-time battery level is greater than or equal to a preset battery level threshold, the collection of the battery's real-time battery level can be retried; the operation of determining whether the battery is connected to a charging device can be performed, or this operation can be triggered periodically. The specific determination can be made based on the hardware conditions or scenario requirements of the application scenario of this invention, and this invention does not impose specific limitations in this regard.
[0107] For example, this optional embodiment can be specifically as follows: When the maximum single-cell voltage of the battery reaches the full charge cutoff voltage, the full charge flag is 1, and the SOC (State of Charge) = 100%, if the charging gun is unplugged, the BMS (Battery Management System) enters a sleep state and should store the full charge flag. After waking up, the full charge flag is still present. When the charging gun is plugged in again, if the SOC is detected to be greater than or equal to 96%, it is determined that the battery meets the anti-float charging strategy triggering condition. Alternatively, when the maximum single-cell voltage of the battery reaches the full charge cutoff voltage, the full charge flag is 1, and the SOC = 100%, if the charging gun is unplugged, the BMS enters a sleep state and should store the full charge flag. After waking up, the full charge flag is still present. When the charging gun is plugged in again, if the SOC is detected to be less than 96%, it is determined that the battery does not meet the anti-float charging strategy triggering condition, thus allowing the battery to enter the charging process.
[0108] Furthermore, the aforementioned connection method between the battery and the charging device can include wired or wireless connection. For example, if the battery is wired to the charging device, it can be connected to the charging device through a wired charging interface (such as a USB charging interface, a charging gun interface, or a charging suction cup interface). If the battery is wirelessly connected to the charging device, it can be connected through a wireless charging interface, specifically by placing the battery's sensor in a magnetic position suitable for wireless charging. Moreover, regardless of whether the connection is via a wired or wireless charging interface, the connection between the battery and the charging device is considered valid when the battery / charging device detects that the corresponding parameters at the corresponding interface meet preset parameter conditions.
[0109] In addition, the aforementioned charging devices may include one or more of the following: charging piles, charging sockets, solar charging panels, wind power charging devices, water power charging devices, solar power charging devices, thermal power charging devices, wireless charging devices, and electromagnetic charging devices, used in combination.
[0110] As can be seen, implementing this optional embodiment can determine whether the battery meets the triggering conditions of the anti-float charging strategy based on the connection status between the battery and the charging device and the real-time power information of the battery. Furthermore, in the specific embodiment, flag information is also combined to assist in the determination, thereby improving the accuracy of determining the triggering of the anti-float charging strategy. This is beneficial for subsequently executing the corresponding target anti-float charging strategy for batteries that meet the triggering conditions.
[0111] 103. When it is determined that the battery meets the triggering conditions of the anti-float charging strategy, the target anti-float charging strategy of the battery is determined based on the battery's attribute information.
[0112] In this embodiment of the invention, as an optional implementation, the battery attribute information may include preset lifespan information, the target anti-float charging strategy of the battery may include a first anti-float charging strategy or a second anti-float charging strategy, and the above-mentioned determination of the target anti-float charging strategy of the battery based on the battery attribute information may include the following operations:
[0113] Determine whether the target value corresponding to the preset lifespan information is greater than or equal to the preset lifespan threshold. If the target value is greater than or equal to the preset lifespan threshold, the first anti-float charging strategy is determined as the target anti-float charging strategy for the battery. If the target value is less than the preset lifespan threshold, the second anti-float charging strategy is determined as the target anti-float charging strategy for the battery.
[0114] The target operation corresponding to the first anti-float charging strategy is to block the charging process of the battery, while the target operation corresponding to the second anti-float charging strategy is to reduce the charging control parameters of the battery.
[0115] In this optional embodiment, the aforementioned attribute information may further include at least one of the following: application object information, battery charging interface information, battery stored capacity information, battery remaining capacity information, battery charging rate information, battery access voltage (current / charge / power) information, battery discharge efficiency information, battery external discharge device information, battery historical charging information, and battery type information.
[0116] In this optional embodiment, the blocking of the battery charging process can be performed at the battery end, at the charging device end, or by coordinating the blocking of the battery and the charging device.
[0117] The attenuation method of the charging control parameters of the battery described above is the same as that of blocking the battery charging process described above, such as attenuation can be performed at the battery end.
[0118] As can be seen, implementing this optional embodiment can determine the target anti-float charging strategy for batteries that meet the triggering conditions of the anti-float charging strategy based on battery lifespan information. This improves the accuracy of determining the target anti-float charging strategy, which not only helps reduce the occurrence of battery float charging and solve the problem of reduced battery lifespan caused by float charging, but also helps to further extend the lifespan of batteries with different properties. Furthermore, limiting the battery charging process can be further implemented through fixed-end or multi-end collaboration, further improving the flexibility of the execution method of the target anti-float charging strategy.
[0119] In this optional embodiment, as an alternative implementation, the aforementioned preset lifespan information can be calculated using a preset regression calculation model based on other attribute information (such as battery access voltage information, battery discharge efficiency information, battery external discharge device information, battery historical charging information, etc.). This preset regression calculation model can be obtained by training the model using the other attribute information through data distillation and data cleaning. Alternatively, the preset regression calculation model can be obtained by superimposing one or more of linear regression, logistic regression, multinomial regression, stepwise regression, ridge regression, and lasso regression through hierarchical training.
[0120] Specifically, the preset regression calculation model may include a first set of regression models and a second regression model. The first set of regression models includes at least one base model, which includes at least one of gradient boosting regression model, extreme tree regression model, random forest regression model, and adaptive boosting regression model. The second regression model includes a linear regression model.
[0121] In this optional embodiment, as an optional implementation method, the training method of the above-mentioned preset regression calculation model may specifically include the following steps:
[0122] The training sample dataset is divided according to the preset cross-validation conditions.
[0123] Each training sample in the divided training sample dataset is input into the corresponding base model to obtain the first prediction result for each training sample and the first target model set corresponding to the first regression model set.
[0124] The first prediction result corresponding to all training sample data is input into the second regression model to obtain the second prediction result corresponding to all training sample data and the second target model corresponding to the second regression model. The second prediction result is used to represent the battery life information corresponding to all predicted training sample data.
[0125] Based on the second prediction results corresponding to all training sample data, the first target model set and the second target model are determined as the prediction models to be verified.
[0126] Input all validation sample data from the validation sample dataset into the prediction model to be validated to obtain the validation results corresponding to all validation sample data. The validation results are used to represent the battery life information corresponding to all the predicted validation sample data.
[0127] Determine whether the verification result meets the preset verification completion conditions. If the verification result meets the preset verification completion conditions, then determine the prediction model to be verified as the target prediction model.
[0128] In this optional embodiment, the number of cross-validations corresponding to the above-mentioned preset cross-validation conditions and the logic for dividing the sample dataset can be selected according to the actual application scenario, and the present invention does not impose specific limitations.
[0129] It is evident that implementing this optional embodiment can also provide a training method for a preset regression calculation model.

[0139] It is evident that implementing this optional embodiment can improve the accuracy of determining the target control parameters, thereby improving the accuracy of executing the target operation corresponding to the target control parameters on the battery. This helps to reduce the occurrence of battery float charging and solve the problem of reduced battery life caused by battery float charging.

[0154] 205. When the target anti-float charging strategy is the second anti-float charging strategy, the charging information of the battery at the current power level is obtained.
[0155] In this embodiment of the invention, the charging information includes current charging information and historical charging information. The current charging information includes at least one of the following: current charging rate, current charging current change rate, current charging temperature change rate, and current charging interaction information. The historical charging information corresponds to the current charging information.
[0156] 206. Determine whether the current charging information matches the historical charging information.
[0157] 207. When it is determined that the current charging information and the historical charging information do not match, the target influencing factors affecting the mismatch between the current charging information and the historical charging information are analyzed according to the preset analysis model.
[0158] Optionally, when it is determined that the current charging information and the historical charging information match, the target operation corresponding to the target anti-float charging strategy will continue to be performed on the battery.
[0159] 208. Based on the target impact factor, perform the target optimization operation corresponding to the target impact factor.
[0160] In this embodiment of the invention, as an optional implementation, the target influencing factor includes at least one of the following: a first influencing factor corresponding to the battery, a second influencing factor corresponding to the battery connection to the charging device, and an influencing factor related to the relationship between the battery and the charging device.
[0161] Furthermore, based on the target impact factor, performing the target optimization operation corresponding to the target impact factor can include the following operations:
[0162] When the target impact factor includes the first impact factor, it is determined whether the battery meets the abnormal charging conditions based on the first impact factor. When it is determined that the battery meets the abnormal charging conditions, the abnormality information of the battery is determined, and the fluid control parameters of the battery are generated based on the abnormality information. Furthermore, the target optimization operation is performed on the battery based on the fluid control parameters, which include gas fluid control parameters or liquid fluid control parameters.
[0163] When the target impact factor includes the second impact factor, the output device corresponding to the charging device is controlled to output a prompt message corresponding to the second impact factor, so as to prompt the user corresponding to the battery about the second impact factor.
[0164] When the target impact factor includes related impact factors, the battery and charging device are controlled to perform collaborative optimization operations based on the related impact factors.
[0165] Optionally, when the target influencing factors include at least two of the first influencing factor, the second influencing factor, and the associated influencing factors, the battery and charging device can determine multiple optimization operation combinations based on at least two of the influencing factors. They can also calculate the optimization complexity of each optimization operation combination and estimate the optimization effectiveness of each combination based on the optimization operations within each combination. Then, based on the optimization complexity, the optimization effectiveness, and the predetermined optimization requirements, they can select one optimization operation combination from all the combinations and perform a matching optimization operation based on the influencing factors corresponding to that combination.
[0166] As can be seen, this optional embodiment can also intelligently and adaptively execute matching optimization operations based on the analyzed influencing factors, which helps to improve the flexibility of the optimization operations and the matching degree between the optimization operations and the battery charging requirements. Furthermore, it can adaptively select matching optimization operation combinations based on the optimization complexity of each optimization operation combination, the optimization effectiveness of each optimization operation combination, and the predetermined optimization requirements, and then execute matching optimization operations based on the selected optimization operation combinations, which can both improve optimization effectiveness and reduce optimization complexity.
[0167] As can be seen, implementing the embodiments of the present invention can further analyze the execution of the strategy based on the latest charging information of the battery after performing the target operation corresponding to the second anti-float charging strategy on the battery. When the current charging information under the strategy execution does not match the historical charging information, the influencing factors affecting the strategy execution will be analyzed, and corresponding optimization operations will be performed based on the influencing factors. Moreover, there are multiple ways to flexibly superimpose and match the optimization operations, which can improve the execution rate of the determined target anti-float charging strategy, thereby helping to reduce the occurrence of battery float charging phenomenon and thus ensuring and extending the battery life.
[0168] In this embodiment of the invention, as an optional implementation, when the target anti-float charging strategy is the first anti-float charging strategy, the above-mentioned target operation corresponding to the target control parameters of the battery may include the following operations:
[0169] The first target information is determined to be the battery's full charge indicator information, so as to block the battery charging process.
[0170] Furthermore, after identifying the first target information as the battery's full charge indicator information to block the battery's charging process, the method may further include the following operations:
[0171] Get the latest real-time battery power information.
[0172] It determines whether the latest real-time battery level is less than the target battery level threshold. If it is determined that the latest real-time battery level is less than the target battery level threshold, the second target information is set as the full charge indicator information to stop blocking the battery charging process.
[0173] If it is determined whether the latest real-time battery level information is greater than or equal to the target battery level threshold, the operation of obtaining the latest real-time battery level information and determining whether the latest real-time battery level information is less than the target battery level threshold will be triggered again.
[0174] Optionally, the above-mentioned full charge indicator information can be full charge flag information, the above-mentioned first target information can be a numerical value, such as 1, and the corresponding second target information can be 0.
[0175] As can be seen, implementing this optional embodiment can automatically block the battery charging process by using full-charge indicator information when the target anti-float charging strategy is the first anti-float charging strategy, simplifying the complexity of the blocking scheme and improving the convenience of scheme execution. Simultaneously, after executing the operation to block the battery charging process, it can determine the adjustment direction of the full-charge indicator information again based on the latest real-time battery power information. When the real-time power information is less than the target power threshold, it can automatically control and stop blocking the battery charging process, improving the automation level of the scheme and thus improving the accuracy of controlling the battery's execution of the anti-float charging strategy.
[0176] In this embodiment of the invention, as another optional implementation, generating the target control parameters based on the target anti-floating charging strategy and the determined battery charging method may include the following operations:
[0177] When the first anti-float charging strategy is determined to be the target anti-float charging strategy, all associated circuits between the battery and the charging device connected to the battery are determined according to the charging method, and the target associated circuit is determined among all associated circuits. Then, the first control parameters are generated according to the blocking control method of the target associated circuit.
[0178] It should be noted that all associated circuits between the battery and the charging device connected to the battery mentioned above include the circuits in the battery and / or the circuits in the charging device.
[0179] Optionally, determining the target associated circuit among all the associated circuits described above may include the following operations:

[0185] Furthermore, optionally, the calculation of the candidate score for the associated circuit based on its circuit complexity and circuit priority may include:
[0186] The first score of the associated circuit is determined based on its circuit complexity, wherein the circuit complexity is inversely proportional to the first score.
[0187] The second score of the associated circuit is determined based on its circuit priority, wherein the circuit priority is directly proportional to the second score.
[0188] Calculate the alternative scores for the associated circuit based on the first and second scores.
[0189] Furthermore, the aforementioned determination of the target associated circuit based on the candidate scores of all associated circuits may include:
[0190] Determine whether there exists a target candidate value with the smallest residual between the candidate scores and the pre-selected candidate scores among all the candidate scores of the associated circuits. If the determination result is yes, then the associated circuit corresponding to the target candidate value is determined as the target associated circuit.
[0191] When the second anti-float charging strategy is determined as the target anti-float charging strategy, the target degradation coefficient of the battery is determined based on the collected real-time temperature information and real-time power information of the battery, and the second control parameters are generated based on the target degradation coefficient and the charging method.
[0192] Optionally, if the requested charging current is C1 when the anti-float charging strategy is not enabled, then when the anti-float charging strategy is enabled, the requested current is K*C1. The attenuation coefficient K can be calibrated according to the SOC range. For example, if the SOC is within [96%, 97%), K = 0.8; if the SOC is within [97%, 98%), K = 0.7; if the SOC is within [98%, 99%), K = 0.6; if the SOC is within [99%, 100%), K = 0.5.
[0193] Furthermore, optionally, when the real-time temperature information of the battery indicates that the real-time temperature of the battery is lower than the preset operating temperature, a preheating operation is first performed on the battery. When the real-time temperature of the battery after preheating is greater than or equal to the preset operating temperature, the operation of determining the target attenuation coefficient of the battery based on the collected real-time temperature information and real-time power information, and generating the second control parameter based on the target attenuation coefficient and the charging method is triggered again.
[0194] Furthermore, performing the target operation corresponding to the target control parameters on the battery can include the following operations:
[0195] Based on the first control parameter, control the target associated circuit to block the charging process; or...
[0196] According to the second control parameter, the target device is controlled to perform a decay operation that matches the second control parameter. The target device includes a battery or a charging device.
[0197] In this optional embodiment, the target association circuit described above can be further specified as the association circuit of the battery cell inside the battery.
[0198] As can be seen, implementing this optional embodiment can determine different control parameters based on the real-time temperature information and real-time power information of the associated circuit or battery when the target anti-float charging strategy is determined to be the first anti-float charging strategy and the second anti-float charging strategy, respectively. This improves the accuracy of the control parameter determination, thereby improving the control accuracy of the battery performing the corresponding target operation. Furthermore, this optional embodiment also discloses a method for determining the target associated circuit, which can determine the target associated circuit in the complex circuit network between the battery and the charging device, thereby improving the control accuracy of blocking the charging process, preventing the impact on the battery and / or other working units of the charging device, and achieving precise blocking.

The first determining module 303 determines the specific method of the target anti-float charging strategy for the battery based on the battery attribute information as follows:
[0207] Determine whether the target value corresponding to the preset lifespan information is greater than or equal to the preset lifespan threshold. If the target value is greater than or equal to the preset lifespan threshold, the first anti-float charging strategy is determined as the target anti-float charging strategy for the battery. If the target value is less than the preset lifespan threshold, the second anti-float charging strategy is determined as the target anti-float charging strategy for the battery.
[0208] The target operation corresponding to the first anti-float charging strategy is to block the charging process of the battery, while the target operation corresponding to the second anti-float charging strategy is to reduce the charging control parameters of the battery.
[0209] As can be seen, implementing this optional embodiment can determine the target anti-float charging strategy for batteries that meet the triggering conditions of the anti-float charging strategy based on battery lifespan information. This improves the accuracy of determining the target anti-float charging strategy, which not only helps reduce the occurrence of battery float charging and solve the problem of reduced battery lifespan caused by float charging, but also helps to further extend the lifespan of batteries with different properties. Furthermore, limiting the battery charging process can be further implemented through fixed-end or multi-end collaboration, further improving the flexibility of the execution method of the target anti-float charging strategy.

[0220] As can be seen, implementing the embodiments of the present invention can further analyze the execution of the strategy based on the latest charging information of the battery after performing the target operation corresponding to the second anti-float charging strategy on the battery. When the current charging information under the strategy execution does not match the historical charging information, the influencing factors affecting the strategy execution will be analyzed, and corresponding optimization operations will be performed based on the influencing factors. Moreover, there are multiple ways to flexibly superimpose and match the optimization operations, which can improve the execution rate of the determined target anti-float charging strategy, thereby helping to reduce the occurrence of battery float charging phenomenon and thus ensuring and extending the battery life.
