[0024] The following describes the battery replacement abnormality detection method, system and electronic device of an embodiment of the present invention with reference to the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described with reference to the accompanying drawings are exemplary and should not be construed as limiting the present invention.

[0025] Figure 1 It is a flow chart of a method for detecting abnormal battery replacement according to an embodiment of the present invention.

[0026] like Figure 1 As shown, the battery replacement abnormality detection method includes:

[0027] S11, obtain the current battery replacement information and historical successful battery replacement information.

[0028] Among them, the information of this battery replacement includes the mileage of this battery replacement and the power of the first battery replaced this time, and the information of historical successful battery replacement includes the historical battery replacement mileage.

[0029] Specifically, when a battery swap station completes a battery swap, it needs to obtain the battery swap information and then send the battery swap information to the cloud. The battery swap information includes information related to the replaced battery and information related to the replaced battery.

[0030] Moreover, the cloud is also configured to save the battery swap information after receiving the battery swap information sent to it by the battery swap station in the past.

[0031] When a battery swap station provides battery swap services, it needs to send the battery swap information to the cloud. After receiving the battery swap information, the cloud also needs to obtain historical successful battery swap information, which includes historical battery swap mileage, which is the battery swap mileage corresponding to the successful battery swap in the past.

[0032] As an example, suppose there is a vehicle that has its battery replaced at a battery swap station. The battery swap station needs to obtain information about this battery swap, including the power of the replaced battery, the power of the replaced battery, the battery swap mileage of the replaced battery, and other information. Then the battery swap station needs to send this battery swap information to the cloud. The above battery swap mileage refers to the additional mileage added to the vehicle by the replaced battery. After receiving the battery swap information, the cloud needs to obtain the vehicle's identity information, and then query the local storage information based on the vehicle's identity information to obtain the vehicle's historical successful battery swap information when it successfully replaced the battery in the past. For example, the vehicle's historical successful battery swap information can be obtained from the last successful battery swap.

[0033] S12, obtaining the battery swap mileage difference based on the current battery swap mileage and the historical battery swap mileage.

[0034] S13, when it is determined that the battery replacement information is abnormal based on at least one of the battery replacement mileage difference and the first battery power, it is determined that the battery replacement is abnormal.

[0035] Specifically, since the battery swap mileage is the driving mileage that the newly replaced battery at the battery swap station can provide, there should theoretically not be too large a gap between the current battery swap mileage and the historical battery swap mileage. Therefore, after obtaining the current battery swap mileage and the historical battery swap mileage, the difference between the current battery swap mileage and the historical battery swap mileage can be calculated, and the difference can be used to determine whether the current battery swap information is abnormal. For example, the battery swap mileage difference can be compared with a preset threshold value, and when the battery swap mileage difference is greater than the preset threshold value, it is determined that the current battery swap information is abnormal. The threshold value can be a fixed value or a freely adjustable value.

[0036] Moreover, the power of the replaced battery can be obtained to obtain the power of the first battery, and then when there is an abnormality in the power of the first battery, it is determined that the battery replacement information is abnormal.

[0037] Moreover, as long as there is at least one anomaly in the battery replacement mileage difference and the first battery power, it can be determined that the battery replacement information is abnormal.

[0038] Therefore, by obtaining the current battery replacement information and the historical successful battery replacement information, wherein the current battery replacement information includes the current battery replacement mileage, and the historical successful battery replacement information includes the historical battery replacement mileage, and the battery replacement mileage difference is obtained based on the current battery replacement mileage and the historical battery replacement mileage, so that when the current battery replacement information is determined to be abnormal based on the battery replacement mileage difference, the current battery replacement is determined to be abnormal, and it can be realized to judge whether the current battery replacement information of the current battery replacement is abnormal, avoid calculating the electricity fee based on the abnormal battery replacement information, and thus avoid the abnormal battery replacement information from damaging the interests of users.

[0039] In some embodiments of the present invention, the battery replacement information also includes the rated kilowatt-hour data of the battery replaced this time, and the historical successful battery replacement information also includes the second battery power of the battery successfully replaced in the past. The abnormality of the battery replacement information is determined based on the battery replacement mileage difference, including: obtaining the upper limit of the battery replacement mileage difference based on the battery replacement mileage difference, the first battery power, the second battery power and the rated kilowatt-hour data; when the battery replacement mileage difference is greater than the upper limit of the battery replacement mileage difference estimated by the system, the battery replacement information is determined to be abnormal.

[0040] The above rated kilowatt-hour data refers to the electrical energy stored in the battery replaced this time, in KWH, see Figure 2 The example shown in Figure 2 In the example shown, the battery replaced this time is a battery on an electric vehicle. It can be seen that the larger the rated power data is, the longer the mileage the vehicle can travel with the support of the battery replaced this time.

[0041] The above rated kilowatt-hour data can be calculated by the capacity and voltage of the battery. Specifically, the battery power can be obtained by the following calculation formula: Power (kilowatt-hour) = battery capacity (in ampere-hour, Ah) × voltage (in volts, V). This calculation formula is used to calculate the total amount of electrical energy that the battery can provide, that is, the above calculated power is the electrical energy that the battery can provide, and this electrical energy is the rated kilowatt-hour data of the battery. For example, if the capacity of a battery is 4 ampere-hours (Ah) and the voltage is 3 volts (V), then according to the above calculation formula, the power (kilowatt-hour) of this battery is 4Ah×3V=12 kilowatt-hours.

[0042] Therefore, after calculating the battery swap mileage difference based on the current battery swap mileage and the historical battery swap mileage, when judging whether the current battery swap information is abnormal based on the battery swap mileage difference, the upper limit of the battery swap battery mileage difference can be first calculated based on the current battery swap information, and then the current battery swap information is determined to be abnormal when the battery swap mileage difference is greater than the upper limit of the battery swap battery mileage difference, thereby realizing real-time calculation of the threshold for comparison with the battery swap mileage difference based on the current battery swap information, and accurately obtaining the upper limit of the battery swap battery mileage difference, thereby realizing accurate judgment of the abnormality of the current battery swap information.

[0043] In some embodiments of the present invention, the above-mentioned replacement point abnormality detection method is used for electric vehicles, and the above-mentioned battery replacement mileage difference upper limit is obtained based on the battery replacement mileage difference, the first battery power, the second battery power and the rated kilowatt-hour data, which may include: obtaining the kilowatt-hour mileage according to the battery replacement mileage difference, the first battery power, and the second battery power, wherein the kilowatt-hour mileage is the kilometres travelled by the electric vehicle when one kilowatt-hour of the battery replaced this time; obtaining the battery replacement mileage difference upper limit based on the kilowatt-hour mileage and the rated kilowatt-hour data.

[0044] The above-mentioned method of obtaining the kilowatt-hour of electricity per time based on the battery replacement mileage difference, the first battery power and the second battery power may include: obtaining the power difference between the first battery power and the second battery power; adding the power difference with the external charging power, and obtaining the product of the addition result and a preset battery degradation coefficient, wherein the external charging power is the power of the external charging of the battery replaced this time; dividing the battery replacement mileage difference by the addition result to obtain the kilowatt-hour of electricity per time.

[0045] The above-mentioned obtaining the upper limit of the battery replacement mileage difference based on the current kilowatt-hour data and the rated kilowatt-hour data may include: obtaining the product of the current kilowatt-hour data and the rated kilowatt-hour data, and using the product as the upper limit of the battery replacement mileage difference.

[0046] The following is an explanation with an example.

[0047] In this example, the historical battery replacement mileage is the battery replacement mileage corresponding to the last successful battery replacement, and the second battery power is the power of the last successful battery replacement.

[0048] Specifically, the kilowatt-hour of electricity per time is: the difference between the current battery replacement mileage and the last battery replacement mileage divided by the external charging power plus the difference between the battery power of the replaced battery and the replaced battery power, which is formulated as current_electric_kilometer=(current_odo-last_odo) / [(external charging power+(last battery replacement power-this battery replacement power))×battery degradation coefficient]. The battery degradation coefficient is the above-mentioned preset battery degradation coefficient.

[0049] The upper limit of the mileage difference of the battery swap is: the rated electricity data of the current battery swap multiplied by the average electricity-kwh of the time, which is the estimated reasonable upper limit of the mileage difference of the current battery swap, and the formula is current_battery_upper_bound_odo_delta=current_battery_kwh×current_electric_kilometer.

[0050] Among them, current_electric_kilometer is the current kilowatt-hours, current_odo is the mileage of this battery replacement, last_odo is the mileage of the battery replacement corresponding to the last successful battery replacement, the power of the last battery replaced is the power of the second battery, the power of the battery replaced this time is the power of the first battery, current_battery_upper_bound_odo_delta is the upper limit of the battery mileage difference at the replacement point, current_battery_kwh is the rated electricity data, and the battery degradation coefficient is the degradation of each battery calculated offline, which is a number greater than 1.

[0051] In some embodiments of the present invention, the abnormality of the current battery replacement information is determined based on the battery replacement mileage difference, including: when the battery replacement mileage difference is less than zero, determining that the current battery replacement information is abnormal.

[0052] Specifically, after obtaining the battery swap mileage difference by subtracting the historical battery swap mileage from the current battery swap mileage, it can also be determined whether the battery swap mileage difference is less than zero. If the battery swap mileage difference is less than zero, it means that the current battery swap mileage is less than the historical battery swap mileage, confirming that the current battery swap information is abnormal.

[0053] In this way, it is possible to further accurately determine whether the battery replacement information is abnormal.

[0054] In some embodiments of the present invention, determining that the information of this battery replacement is abnormal is based on the power of the first battery, including: when the power of the first battery is less than zero, determining that the information of this battery replacement is abnormal.

[0055] Specifically, after the battery swap service is provided at the battery swap station, the power level of the first battery of the replaced battery can also be obtained. If the power level of the first battery is less than zero, it means that there is a problem with the information sent to the cloud this time, and then it is determined that the battery swap information is abnormal.

[0056] It should be noted that the above-mentioned determination of whether the power level of the first battery is less than zero is only a specific embodiment, and is not limited to this in actual applications, as long as it is possible to determine whether there is any abnormality in the current battery replacement information.

[0057] In some embodiments of the present invention, the battery swap abnormality detection method also includes: when the battery swap completion information sent by the battery swap station is not received, sending a compensation instruction to the battery swap station, wherein the battery swap station is a battery swap station that provides the current battery swap service to the electric vehicle, and the compensation instruction is an instruction instructing the battery swap station to resend the battery swap completion information; if the battery swap completion information sent by the battery swap station in response to the compensation instruction is not received, it is determined that the current battery swap is abnormal.

[0058] Specifically, after providing the battery swap service, the battery swap station is set to report the battery swap completion information to the cloud. Therefore, if the cloud does not receive the corresponding battery swap completion information after determining that the battery swap station provides the battery swap service, it is necessary to send a compensation instruction to the battery swap station. If the battery swap completion information sent by the battery swap station in response to the compensation instruction is not received, a supplementary instruction is sent again. After repeatedly sending the compensation instruction N times, if the battery swap completion information sent by the battery swap station in response to the compensation instruction is still not received, it is determined that this battery swap is abnormal.

[0059] The following is an explanation with a specific example.

[0060] In this example, a data receiving module, an abnormality detection module, and an abnormality handling module are set. The data receiving module includes a battery replacement process data receiving submodule and a battery charging process data receiving submodule, the abnormality detection module includes an abnormality rule management submodule, an abnormality detection submodule, and an abnormality detection warning submodule, and the abnormality handling module includes a retry processing submodule and a manual processing submodule.

[0061] Among them, the exception rule management submodule is used to manage exception rules based on expert experience. Specifically, based on expert experience, define exception conditions and store these defined exception rules so that the system can retrieve and apply them when needed. The specific rules used include negative exceptions when the battery replacement mileage difference is negative, excessive battery replacement mileage difference is abnormal, negative battery power when replaced is abnormal, and battery power when replaced exceeds the rated kWh.

[0062] The abnormality detection submodule is used for rule-based detection. For example, when the battery swap station reports the completion of the battery swap, its data is processed, the abnormal rules managed by the abnormal rule management submodule are obtained, the processed data is input into the rules, and abnormality detection is performed in sequence according to the rules. For another example, detection based on the time series analysis algorithm: based on the data stored in the battery charging process data receiving submodule, time series analysis is used to identify the data pattern in the battery charging timing data, and by comparing the actual data with the historical data, the abnormal values ​​that deviate significantly from the normal range are identified.

[0063] The abnormal detection and warning module is used to send abnormal data information and general information (vehicle, station, user, etc.) to the station staff on duty when an abnormality is detected. It can also correct the data on the cloud platform system and then generate normal battery replacement settlement amount information.

[0064] The retry processing submodule is used to perform timeout retry compensation after the cloud sends the start of battery replacement. If the timeout threshold (such as 5 minutes) is reached and the battery replacement completion message reported by the battery replacement station has not been received, a compensation instruction will be issued to let it resend the battery replacement completion message.

[0065] The manual processing submodule is used to support service support personnel to obtain reasonable battery replacement process data, such as battery replacement mileage and battery power, and input the corrected data into the system through the exception handling module.

[0066] Combine the following Figure 3 Provide explanation.

[0067] exist Figure 3 In the example, the station end is a switching station and the station end serves electric vehicles.

[0068] See also Figure 3 After the station needs to provide battery replacement services for electric vehicles, it needs to report the battery replacement completion information to the cloud.

[0069] Therefore, if the cloud does not receive the battery swap completion information sent by the station, the cloud needs to send a compensation instruction to the station, and if the battery swap completion information sent by the station in response to the compensation instruction is not received, the compensation instruction needs to be reissued. If the battery swap completion information sent by the station is still not received after the compensation instruction is reissued N times, the compensation is determined to have failed and an abnormality detection alarm is issued.

[0070] If the point change completion information is received, the cloud receives the data reported by the station. Among them, after the station provides the battery replacement service for the electric vehicle, it also needs to send the battery replacement information related to this battery replacement service to the cloud. This battery replacement information includes VIN, ODO, the power of the replaced battery, the power of the replaced battery, external charging information, etc. The above-mentioned VIN is the identification of the electric vehicle, the above-mentioned ODO is the mileage of this battery replacement, the power of the replaced battery is the power of the first battery, and the power of the replaced battery is the power of the battery replaced this time, which can be represented by the above-mentioned rated kilowatt-hour data, and the external charging information includes the above-mentioned external charging power.

[0071] After receiving the above information, the cloud obtains the historical successful battery replacement information based on the VIN query. In this example, the historical successful battery replacement information is the battery replacement information of the last successful battery replacement, which also includes ODO data, battery power and other data. Among them, the ODO data included in the historical successful battery replacement information is the above-mentioned historical battery replacement mileage, and the battery power includes the above-mentioned second battery power.

[0072] After obtaining the above information, abnormality detection can be performed. Specifically, the current battery replacement mileage is subtracted from the last battery replacement mileage to obtain the ODO difference, which is the above battery replacement mileage difference, and it is determined whether the ODO difference is negative, whether the first battery power is negative, and whether the battery replacement mileage difference is greater than a threshold value, which is the upper limit of the battery replacement mileage difference.

[0073] When one of the above three conditions is true, it is confirmed that the battery replacement information is abnormal and an abnormal detection alarm is issued.

[0074] In summary, the battery replacement abnormality detection method of the embodiment of the present invention obtains the current battery replacement information and the historical successful battery replacement information, wherein the current battery replacement information includes the current battery replacement mileage, and the historical successful battery replacement information includes the historical battery replacement mileage, and the battery replacement mileage difference is obtained according to the current battery replacement mileage and the historical battery replacement mileage. Therefore, when it is determined that the current battery replacement information is abnormal according to the battery replacement mileage difference, the current battery replacement is determined to be abnormal, so as to realize the judgment of whether the current battery replacement information of the current battery replacement is abnormal, thereby avoiding the abnormal battery replacement information from damaging the interests of users.

The bus 502 may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 4 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0080] The memory 503 is used to store a computer program corresponding to the battery replacement abnormality detection method of the above embodiment of the present invention, and the computer program is controlled and executed by the processor 501. The processor 501 is used to execute the computer program stored in the memory 503 to implement the content shown in the above method embodiment.

Therefore, when it is determined that the current battery replacement information is abnormal based on the battery replacement point mileage difference, it is determined that the current battery replacement is abnormal, so that it can be judged whether the current battery replacement information of the current battery replacement is abnormal, thereby avoiding the abnormal battery replacement information from damaging the interests of users.

[0083] Furthermore, the present invention proposes a battery replacement abnormality detection system.

[0084] Figure 5 It is a structural block diagram of the battery replacement abnormality detection system according to an embodiment of the present invention.

[0085] like Figure 5 As shown, the battery swap abnormality detection system 10 includes a cloud 100 and a battery swap station 200. The cloud 100 is connected to the battery swap station 200. The battery swap station 200 is used to send the battery swap information to the cloud 100. The battery swap information includes the battery swap mileage.
