[0084] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0085] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present disclosure, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0086] In addition, the technical solutions between the various implementation methods can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this disclosure.

[0087] BMS (Battery Management System) usually provides various information about the battery, including the battery model, capacity, voltage, current, temperature, number of cycles, charging status, etc. The present disclosure can determine the model of the battery swap according to the BMS data of the battery swap, and then detect the status of the battery swap based on the communication protocol corresponding to the model.

[0088] Figure 1 A method for detecting abnormality of a battery replacement provided by the present disclosure is shown. Figure 1 , the detection method comprises the following steps:

[0089] S101. Determine the model of the battery replacement battery according to the BMS data of the battery replacement battery;

[0090] S102, obtaining status information of the battery replacement battery based on a communication protocol corresponding to the model of the battery replacement battery;

[0091] S103. Determine abnormal batteries according to the status information.

[0092] Different types of battery replacement batteries use different communication protocols. For example, the CAN (Controller Area Network) bus protocol is widely used to communicate with BMS in automobiles, electric vehicles and industrial applications. Modbus (a serial communication protocol) is commonly used to monitor and control the status of BMS in the field of industrial automation.

[0093] In this embodiment, the model of the battery replacement battery is first determined based on the BMS data of the battery replacement battery, and then the status information of the battery replacement battery is correctly obtained based on the communication protocol corresponding to the model, and the battery replacement battery is reliably and accurately detected based on the status information to determine the abnormal battery.

[0094] Since battery swaps made of different materials have different requirements for temperature and voltage, the corresponding preset state requirements can be determined based on the material of the battery swap, and then abnormal batteries can be identified by judging whether the state information of the battery swap meets the preset state requirements.

[0095] As a feasible implementation, step S103 includes:

[0096] Obtain materials for battery replacement;

[0097] Determine the corresponding preset state requirements based on the material;

[0098] If the status information does not meet the preset status requirements, the replaced battery is determined to be an abnormal battery.

[0099] Generally speaking, the material of the swap battery can be determined based on the model, specifications and performance parameters of the swap battery.

[0100] In step S103, the abnormal battery replacement battery can be determined based on the battery temperature. Specifically, the abnormal battery can be determined based on at least one state information of the whole battery pack temperature information, the single battery temperature information and the battery temperature change information.

[0101] As a feasible implementation, the status information includes temperature information of the entire battery pack. Accordingly, step S103 includes:

[0102] If the temperature information of the entire battery pack indicates that the current temperature of the replacement battery is outside the preset temperature range, the replacement battery is determined to be an abnormal battery.

[0103] Specifically, the preset temperature range includes a preset maximum temperature and a preset minimum temperature. If the current temperature of the battery replacement battery exceeds the preset maximum temperature or is lower than the preset minimum temperature, it can be determined that the battery replacement battery is abnormal.

[0104] The above-mentioned implementation method monitors the temperature of the entire battery pack of the battery replacement battery, promptly detects the battery replacement battery that exceeds the preset temperature range, and then determines it as an abnormal battery.

[0105] It should be noted that a battery pack may generally include multiple cells, which are generally connected together to form a battery pack. The cells in the battery pack may be connected in series or in parallel to meet the voltage, capacity and power requirements of different applications.

[0106] However, if there is an uneven discharge problem in the single cells of the battery swap, the battery life will be shortened and the performance will be unstable. Excessive temperature differences may increase the safety risk of the battery swap. Therefore, it is also necessary to monitor the temperature of the single cells in the battery swap.

[0107] As a feasible implementation manner, the state information includes single cell temperature information; accordingly, step S103 includes:

[0108] If the single-cell battery temperature information indicates that the maximum temperature difference between any two single-cell batteries in the battery replacement battery exceeds the preset temperature difference threshold, the battery replacement battery is determined to be an abnormal battery.

[0109] Specifically, the temperature difference between every two single cells in the battery replacement battery can be calculated based on the single cell temperature information to determine the maximum temperature difference. If the maximum temperature difference exceeds the preset temperature difference threshold, it can be determined that there is an abnormality in the battery replacement battery.

[0110] The above-mentioned implementation method monitors the temperature of the single cells in the battery replacement battery, and can promptly detect the battery replacement battery with a large temperature difference between the single cells, and then determine it as an abnormal battery.

[0111] As a feasible implementation, the state information includes battery temperature change information. Accordingly, step S103 includes:

[0112] If the battery temperature change information indicates that the temperature change difference of the replacement battery within the first preset time interval exceeds the preset temperature change threshold, the replacement battery is determined to be an abnormal battery.

[0113] Specifically, the temperature information of the entire battery pack of the battery swap can be obtained once every first preset time interval, and the difference between two adjacent pieces of temperature information of the entire battery pack can be calculated to obtain the battery temperature change difference. If the battery temperature change difference exceeds the preset temperature change threshold, it can be considered that the temperature of the battery swap has changed drastically, and then the battery swap can be determined to be an abnormal battery.

[0114] The above-mentioned implementation method monitors the temperature changes of the battery-swap battery, and can promptly detect the battery-swap battery with drastic temperature changes, and then determine it as an abnormal battery.

[0115] In step S103, the battery replacement battery with abnormality can also be determined based on the battery voltage. Specifically, the abnormal battery can be determined based on at least one of the status information of the whole pack battery voltage information, the single cell battery voltage information, and the single cell battery voltage information.

[0116] As a feasible implementation, the status information includes the voltage information of the entire battery pack. Accordingly, step S103 includes:

[0117] If the voltage information of the entire battery pack indicates that the voltage value of the replacement battery is outside the preset voltage range, it is determined that the replacement battery is an abnormal battery.

[0118] The above-mentioned implementation method monitors the battery voltage of the entire pack of swap batteries, and can promptly detect swap batteries that exceed the preset voltage range, and then determine them as abnormal batteries.

[0119] As a feasible implementation, the state information includes single cell voltage information. Accordingly, step S103 includes:

[0120] If the single-cell battery voltage information indicates that the maximum voltage difference between any two single-cell batteries in the replacement battery exceeds the preset voltage difference threshold, the replacement battery is determined to be an abnormal battery.

[0121] The above-mentioned implementation method monitors the voltage of the single cells in the battery replacement battery, and can promptly detect the battery replacement battery with a large voltage difference between the single cells, and then determine it as an abnormal battery.

[0122] As a feasible implementation manner, the state information includes battery voltage change information; accordingly, step S103 includes:

[0123] If the battery voltage change information indicates that the voltage change difference of the replacement battery within the second preset time interval exceeds the preset voltage change threshold, the replacement battery is determined to be an abnormal battery.

[0124] The above-mentioned implementation method can timely detect the battery replacement battery with drastic voltage changes by monitoring the voltage changes of the battery replacement battery, and then determine it as an abnormal battery.

[0125] On the basis of determining the abnormal battery according to different status information, the corresponding abnormal duration threshold can also be set to reduce misjudgment.

[0126] In addition, after step S103, the above detection method further includes step S104, generating prompt information corresponding to the abnormal battery.

[0127] Exemplarily, if the abnormal battery is determined based on the temperature information of the entire battery pack, a first temperature alarm prompt message may be generated. The first temperature alarm prompt message may include the current temperature of the abnormal battery. If the abnormal battery is determined based on the temperature information of the single battery, a second temperature alarm prompt message may be generated. The second temperature alarm prompt message may include information of two single batteries corresponding to the maximum temperature difference. If the abnormal battery is determined based on the battery temperature change information, a third temperature alarm prompt message may be generated. The third temperature alarm prompt message may include the first preset time interval, the temperature change difference, and the current temperature of the abnormal battery.

[0128] Similarly, if the abnormal battery is determined based on the voltage information of the entire battery pack, a first voltage alarm prompt information can be generated. The first voltage alarm prompt information may include the current voltage of the abnormal battery. If the abnormal battery is determined based on the voltage information of the single battery, a second voltage alarm prompt information may be generated. The second voltage alarm prompt information may include information of two single batteries corresponding to the maximum voltage difference. If the abnormal battery is determined based on the battery voltage change information, a third voltage alarm prompt information may be generated. The third voltage alarm prompt information may include a second preset time interval, a voltage change difference, and the current voltage of the abnormal battery.

[0129] Furthermore, in order to clarify which battery or batteries have an abnormality, the battery status information obtained by the disclosed embodiment also includes the battery storage location number and / or battery code of the battery storage location, and the generated prompt information includes the battery storage location number and / or battery code of the abnormal battery. According to the battery storage location number and battery code of the abnormal battery in the prompt information, it is convenient for users to quickly locate the abnormal battery.

[0130] As a feasible implementation method, the status information also includes the storage location number of the replacement battery, and the prompt information also includes the storage location number of the abnormal battery.

[0131] As another feasible implementation, the status information also includes the battery code of the replacement battery, and the prompt information also includes the battery code of the abnormal battery.

[0132] Furthermore, after step S104, step S105 is also included, in which an early warning is issued in a preset manner according to the prompt information.

[0133] Among them, the preset method includes at least one of generating a warning pop-up window, playing a warning ringtone, making a warning call, sending a warning text message, and sending a warning email.

[0134] The above implementation manner pushes prompt information to the user in a timely manner through one or more preset methods, so that the user can handle the abnormal battery in a timely manner.

[0135] Figure 2 A battery replacement abnormality detection system provided by the present disclosure is shown. Figure 2 , the detection system includes:

[0136] A model determination module 201 is used to determine the model of the battery replacement battery according to the BMS data of the battery replacement battery;

[0137] A status acquisition module 202 is used to acquire status information of the battery replacement battery based on a communication protocol corresponding to the model of the battery replacement battery;

[0138] The abnormality detection module 203 is used to determine abnormal batteries according to the status information.

[0139] Different types of battery replacement batteries use different communication protocols. For example, the CAN bus protocol is widely used to communicate with BMS in automobiles, electric vehicles, and industrial applications. Modbus is commonly used to monitor and control the status of BMS in the field of industrial automation.

[0140] In this embodiment, the model of the battery replacement battery is first determined based on the BMS data of the battery replacement battery, and then the status information of the battery replacement battery is correctly obtained based on the communication protocol corresponding to the model, and the battery replacement battery is reliably and accurately detected based on the status information to determine the abnormal battery.

[0142] Since battery swaps made of different materials have different requirements for temperature and voltage, the corresponding preset state requirements can be determined based on the material of the battery swap, and then abnormal batteries can be identified by judging whether the state information of the battery swap meets the preset state requirements.

[0143] As a feasible implementation, the anomaly detection system 203 is used to:

[0144] Obtain materials for battery replacement;

[0145] Determine the corresponding preset state requirements based on the material;

[0146] If the status information does not meet the preset status requirements, the replaced battery is determined to be an abnormal battery.

[0147] Generally speaking, the material of the swap battery can be determined based on the model, specifications and performance parameters of the swap battery.

[0148] For the abnormality detection module 203, the abnormal battery can be determined based on the temperature of the battery. Specifically, the abnormal battery can be determined based on at least one state information of the whole battery pack temperature information, the single battery temperature information and the battery temperature change information.

[0149] As a feasible implementation, the status information includes the temperature information of the whole battery pack. Accordingly, the abnormality detection module 203 is used to:

[0150] If the temperature information of the entire battery pack indicates that the current temperature of the replacement battery is outside the preset temperature range, the replacement battery is determined to be an abnormal battery.

[0151] Specifically, the preset temperature range includes a preset maximum temperature and a preset minimum temperature. If the current temperature of the battery replacement battery exceeds the preset maximum temperature or is lower than the preset minimum temperature, it can be determined that the battery replacement battery is abnormal.

[0152] The above-mentioned implementation method monitors the temperature of the entire battery pack of the battery replacement battery, so as to promptly detect the battery replacement battery that exceeds the preset temperature range, and then determine it as an abnormal battery.

[0153] It should be noted that a battery pack usually includes multiple cells, which are usually connected together to form a battery pack. The cells in the battery pack can be connected in series or in parallel to meet the voltage, capacity and power requirements of different applications.

[0154] However, if there is an uneven discharge problem in the single cells of the battery swap, the battery life will be shortened and the performance will be unstable. Excessive temperature differences may increase the safety risk of the battery swap. Therefore, it is also necessary to monitor the temperature of the single cells in the battery swap.

[0155] As a feasible implementation, the state information includes the temperature information of the single battery; accordingly, the abnormality detection module 203 is used to:

[0156] If the single-cell battery temperature information indicates that the maximum temperature difference between any two single-cell batteries in the battery replacement battery exceeds the preset temperature difference threshold, the battery replacement battery is determined to be an abnormal battery.

[0157] Specifically, the temperature difference between every two single cells in the battery replacement battery can be calculated based on the single cell temperature information to determine the maximum temperature difference. If the maximum temperature difference exceeds the preset temperature difference threshold, it can be determined that there is an abnormality in the battery replacement battery.

[0158] The above-mentioned implementation method monitors the temperature of the single cells in the battery replacement battery, and can promptly detect the battery replacement battery with a large temperature difference between the single cells, and then determine it as an abnormal battery.

[0159] As a feasible implementation, the state information includes battery temperature change information. Accordingly, the abnormality detection module 203 is used to:

[0160] If the battery temperature change information indicates that the temperature change difference of the replacement battery within the first preset time interval exceeds the preset temperature change threshold, the replacement battery is determined to be an abnormal battery.

[0161] Specifically, the temperature information of the entire battery pack of the battery swap can be obtained once every first preset time interval, and the difference between two adjacent pieces of temperature information of the entire battery pack can be calculated to obtain the battery temperature change difference. If the battery temperature change difference exceeds the preset temperature change threshold, it can be considered that the temperature of the battery swap has changed drastically, and then the battery swap can be determined to be an abnormal battery.

[0162] The above-mentioned implementation method monitors the temperature changes of the battery-swap battery, and can promptly detect the battery-swap battery with drastic temperature changes, and then determine it as an abnormal battery.

[0163] For the abnormality detection module 203, the abnormal battery replacement can also be determined based on the battery voltage. Specifically, the abnormal battery can be determined based on the whole pack battery voltage information, the single cell battery voltage information, and at least one of the single cell battery voltage information.

[0164] As a feasible implementation, the status information includes the voltage information of the entire battery pack. Accordingly, the abnormality detection module 203 is used to:

[0165] If the voltage information of the entire battery pack indicates that the voltage value of the replacement battery is outside the preset voltage range, it is determined that the replacement battery is an abnormal battery.

[0166] The above-mentioned implementation method monitors the battery voltage of the entire pack of swap batteries, and can promptly detect swap batteries that exceed the preset voltage range, and then determine them as abnormal batteries.

[0167] As a feasible implementation, the state information includes single cell voltage information. Accordingly, the abnormality detection module 203 is used to:

[0168] If the single-cell battery voltage information indicates that the maximum voltage difference between any two single-cell batteries in the replacement battery exceeds the preset voltage difference threshold, the replacement battery is determined to be an abnormal battery.

[0169] The above-mentioned implementation method monitors the voltage of the single cells in the battery replacement battery, and can promptly detect the battery replacement battery with a large voltage difference between the single cells, and then determine it as an abnormal battery.

[0170] As a feasible implementation manner, the state information includes battery voltage change information; accordingly, the abnormality detection module 203 is used to:

[0171] If the battery voltage change information indicates that the voltage change difference of the replacement battery within the second preset time interval exceeds the preset voltage change threshold, the replacement battery is determined to be an abnormal battery.

[0172] The above-mentioned implementation method can timely detect the battery replacement battery with drastic voltage changes by monitoring the voltage changes of the battery replacement battery, and then determine it as an abnormal battery.

[0173] On the basis of determining the abnormal battery according to different status information, the corresponding abnormal duration threshold can also be set to reduce misjudgment.

[0174] In addition, the above detection system also includes an early warning module, which is used to generate prompt information corresponding to abnormal batteries.

[0175] Exemplarily, if the abnormal battery is determined based on the temperature information of the entire battery pack, a first temperature alarm prompt message may be generated. The first temperature alarm prompt message may include the current temperature of the abnormal battery. If the abnormal battery is determined based on the temperature information of the single battery, a second temperature alarm prompt message may be generated. The second temperature alarm prompt message may include information of two single batteries corresponding to the maximum temperature difference. If the abnormal battery is determined based on the battery temperature change information, a third temperature alarm prompt message may be generated. The third temperature alarm prompt message may include the first preset time interval, the temperature change difference, and the current temperature of the abnormal battery.

[0176] Similarly, if the abnormal battery is determined based on the voltage information of the entire battery pack, a first voltage alarm prompt information can be generated. The first voltage alarm prompt information may include the current voltage of the abnormal battery. If the abnormal battery is determined based on the voltage information of the single battery, a second voltage alarm prompt information may be generated. The second voltage alarm prompt information may include information of two single batteries corresponding to the maximum voltage difference. If the abnormal battery is determined based on the battery voltage change information, a third voltage alarm prompt information may be generated. The third voltage alarm prompt information may include a second preset time interval, a voltage change difference, and the current voltage of the abnormal battery.

[0177] Furthermore, in order to clarify which battery or batteries have an abnormality, the battery status information obtained by the disclosed embodiment also includes the battery storage location number and / or battery code of the battery storage location, and the generated prompt information includes the battery storage location number and / or battery code of the abnormal battery. According to the battery storage location number and battery code of the abnormal battery in the prompt information, it is convenient for users to quickly locate the abnormal battery.

[0178] As a feasible implementation method, the status information also includes the storage location number of the replacement battery, and the prompt information also includes the storage location number of the abnormal battery.

[0179] As another feasible implementation, the status information also includes the battery code of the replacement battery, and the prompt information also includes the battery code of the abnormal battery.

[0180] Furthermore, the early warning module is also used to: issue an early warning in a preset manner according to the prompt information.

[0181] Among them, the preset method includes at least one of generating a warning pop-up window, playing a warning ringtone, making a warning call, sending a warning text message, and sending a warning email.

[0182] The above implementation manner pushes prompt information to the user in a timely manner through one or more preset methods, so that the user can handle the abnormal battery in a timely manner.
