[0052] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, storage, and display, etc.), and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the crosstalk signals and user information involved in this application are all obtained with full authorization.

[0053] Please refer to Figure 1 , which shows a schematic diagram of the implementation environment of the vehicle battery control method shown in an exemplary embodiment of the present application; the implementation environment includes: a vehicle controller 10, a vehicle energy storage system 20, a vehicle load system 30, a battery charge and discharge positive circuit 40, and a battery charge and discharge negative circuit 50. Among them, the vehicle controller 10 includes a battery management system 11 (BMS, BATTERY MANAGEMENT SYSTEM) and a vehicle control unit (VCU, Vehicle Control Unit). The battery management system 11 is used to control the battery circuit, and the vehicle control unit is used to manage and control many functions of the vehicle, including but not limited to power transmission, braking, steering, etc. The vehicle energy storage system 20 includes a battery module, and the battery module includes at least one group of batteries. The vehicle load system 30 includes multiple electrical appliances. The battery management system 11 controls the battery module to supply power to multiple electrical appliances through the battery charge and discharge positive circuit 40 and the battery charge and discharge negative circuit 50.

[0054] The battery circuit includes multiple signal lines, and the battery and electrical appliances are connected through multiple signal lines, with one signal line corresponding to at least one electrical appliance. Electromagnetic interference on one signal line can couple to other signal lines, interfering with them, generating crosstalk signals in the circuit. When any electrical appliance malfunctions, the crosstalk signal in the circuit will increase abnormally, causing significant interference to other signal lines, such as increasing the voltage and current transmitted in other signal lines, thereby affecting the normal use of the battery and other electrical appliances. The signal value of the crosstalk signal is generally positively correlated with the battery discharge current; that is, the greater the current, the greater the signal value. Therefore, if the crosstalk signal increases abnormally, the signal value can be reduced by reducing the current.

[0055] The vehicle controller 10 detects crosstalk signals in the battery circuit and controls the current in the circuit based on the signal value of the detected crosstalk signal. This process is described in detail in subsequent embodiments. The vehicle in the embodiments of the present application can be a new energy vehicle or a fuel vehicle; new energy vehicles include pure electric vehicles or hybrid vehicles.

[0056] Please refer to Figure 2 , which shows a flow chart of a vehicle battery control method according to an exemplary embodiment of the present application. Figure 2 , the method comprising:

[0057] Step 201: During the use of the vehicle battery, the vehicle controller performs real-time detection of crosstalk signals on the battery circuit to obtain signal values ​​of the crosstalk signals at multiple time points. The use process refers to the charging process or the discharging process. The crosstalk signal refers to the electromagnetic interference on a signal line in the circuit coupled to other signal lines to interfere with the other signal lines. One signal line corresponds to at least one electrical appliance in the circuit.

[0058] The circuit includes multiple appliances, which are connected to the battery via signal lines. In other words, the battery supplies power to these appliances via signal lines, so the signal lines are also the wires in the battery circuit. Appliances can be connected in series or in parallel, so each signal line corresponds to at least one appliance. These appliances include various electrical devices such as air conditioners, lights, car refrigerators, and electric doors.

[0059] It should be noted that generally only high-frequency signals will cause interference to other signal lines, so this embodiment takes a high-frequency crosstalk signal as an example for explanation. A high-frequency crosstalk signal refers to a signal with a frequency greater than a preset frequency, which can be set and changed as needed.

[0060] In an embodiment of the present application, the crosstalk signal is detected in real time to obtain signal values ​​at multiple time points. The duration between adjacent time points can be set as needed, that is, the detection period of the crosstalk signal can be set as needed.

[0061] The signal value may be a voltage value or a current value. Optionally, the crosstalk signal on the circuit is detected by a measuring device such as a network analyzer, an oscilloscope, or a spectrum analyzer.

[0062] Step 202 : When the signal value at the current time point is greater than a preset threshold, the vehicle controller determines a target signal value at the current time point based on the signal values ​​at the current time point and at multiple time points before the current time point.

[0063] Among them, the signal value at any time point may be too large or too small due to accidental errors. In order to improve the accuracy of the signal value at the current time point, the target signal value at the current time point is determined based on the signal values ​​of the current time point and multiple time points before the current time point. This process includes the following two implementation methods.

[0064] A first implementation method: The vehicle controller determines the average value of the signal values ​​at the current time point and multiple time points before the current time point as the target signal value at the current time point.

[0065] Since the battery is used when the vehicle is started, the multiple time points before the current time point are also the time points between the vehicle start and the current time point.

[0066] In this embodiment, the average value of the signal values ​​at the current time point and the previous time point is used as the target signal value at the time point, thereby avoiding misjudgment caused by detection error of the signal value and improving the accuracy of crosstalk signal detection.

[0067] The second implementation method: The vehicle controller weights and sums the signal values ​​of the current time point and multiple time points before the current time point to obtain the target signal value. The weight of each time point is negatively correlated with the time length from the time point to the current time point.

[0068] The weight of each time point is negatively correlated with the time distance between the time point and the current time point, that is, the longer the time distance between each time point and the current time point, the smaller the weight of the time point.

[0069] In this implementation, the signal values ​​at multiple time points are weighted and summed to obtain the target signal value at the current time point, avoiding misjudgment caused by signal value detection errors. The farther the signal value is from the current time point, the smaller the impact. The weighted summation is then performed based on the time length from each time point to the current time point, further improving the accuracy of crosstalk signal detection.

[0070] In which case, when the signal value at the current time point is greater than the preset threshold, the signal value at the next time point is continuously detected.

[0071] Step 203: When the target signal value is greater than a preset threshold, the vehicle controller outputs a warning message, which is used to prompt the user to reduce the current of the battery during use.

[0072] Wherein, the warning information can be outputted through at least one of the display screen and the speaker of the vehicle. Further, the warning information can also be sent to a terminal (such as a mobile phone) used by the user so that the user can also receive the warning information in time when not in the vehicle.

[0073] In some embodiments, the vehicle controller also prompts the user of the current adjustment value. Accordingly, the method also includes: when the target signal value is greater than a preset threshold, the vehicle controller determines a second current adjustment parameter corresponding to the target signal value based on the target signal value and a second correspondence, the second correspondence is used to indicate the correspondence between the target signal value and the second current adjustment parameter, and the second current adjustment parameter is positively correlated with the target signal value in the second correspondence; the vehicle controller outputs the second current adjustment parameter, and the second current adjustment parameter is used to instruct the user to reduce the current of the battery during use based on the second current adjustment parameter.

[0074] The second current adjustment parameter is positively correlated with the target signal value; that is, the larger the target signal value, the larger the second current adjustment parameter. Since a larger target signal value increases interference with the battery and electrical devices, and the crosstalk signal value decreases as the current decreases, determining the current adjustment amount based on the signal value improves targeting and accuracy, thereby achieving effective control of the crosstalk signal while minimizing the impact of current reduction.

[0075] In some embodiments, the vehicle controller detects crosstalk signals on multiple signal lines on the loop separately, determines the appliance on the signal line whose target signal value is greater than a preset threshold as the first appliance, and the vehicle controller outputs the first appliance, which is used to prompt the user to reduce the current of the battery during use by reducing the current on the first appliance.

[0076] In this embodiment, if the target signal value on any signal line is greater than a preset threshold, the current on the signal line may increase, which may cause the current to be greater than the safe operating range of the electrical appliance on the signal line, thereby damaging the electrical appliance; in this embodiment, the user is prompted to reduce the current on the first electrical appliance, which not only reduces the current of the battery during use, but also improves the accuracy of current adjustment.

[0077] It should be noted that if the target signal value at the current time point is detected to be greater than the preset threshold, the warning message will continue to be output until the battery current drops to the current threshold. In other words, the warning message will not be canceled until the user reduces the current to the current threshold based on the warning message.

[0078] The current threshold is the current required for the battery and the electrical appliance to operate normally. The current threshold can be a fixed value or a current value determined based on the second current adjustment parameter.

[0079] Optionally, the vehicle controller includes a battery management system and a vehicle controller, the battery management system is used to detect crosstalk signals, and the vehicle controller is used to output alarm information.

[0080] If the target signal value is not greater than the preset threshold, the signal value at the next time point is detected.

[0081] Step 204 : When the target signal value is greater than a preset threshold and the cumulative duration of the signal value greater than the preset threshold reaches a preset duration, the vehicle controller determines a first current adjustment parameter of the battery based on multiple signal values ​​greater than the preset threshold in the crosstalk signal.

[0082] Because high and prolonged crosstalk increases the probability of damage to the battery and electrical appliances, the vehicle controller automatically reduces the battery current to reduce the crosstalk signal. The cumulative duration is the time from the first time the signal value exceeded the preset threshold to the current time.

[0083] Among them, when the signal value of the crosstalk signal is greater than the preset threshold, it means that the crosstalk signal has become abnormal, and then the cumulative duration of the abnormal crosstalk signal is detected to determine whether the abnormal crosstalk signal continues, that is, to determine whether the user has reduced the current based on the warning information. When the current is not reduced and the signal value is not reduced, the vehicle controller is required to automatically force the battery current to be reduced.

[0084] In some embodiments, the process of the vehicle controller determining the first current adjustment parameter of the battery based on multiple signal values ​​greater than a preset threshold in the crosstalk signal includes the following two implementation methods.

[0085] The first implementation method: the vehicle controller determines the average value between multiple signal values ​​greater than a preset threshold in the crosstalk signal, and determines the first current adjustment parameter corresponding to the average value based on the average value and a first correspondence. The first correspondence is used to indicate the correspondence between the signal value and the first current adjustment parameter. In the first correspondence, the first current adjustment parameter is positively correlated with the signal value.

[0086] The first current adjustment parameter is positively correlated with the signal value; that is, the larger the signal value, the larger the first current adjustment parameter. Since a larger signal value increases interference with the battery and electrical appliances, and crosstalk signals weaken as current decreases, determining the first current adjustment parameter based on the signal value improves targeting and accuracy, thereby effectively controlling crosstalk signals while minimizing the impact of current reduction.

[0087] A second implementation method: the vehicle controller determines a maximum signal value among multiple signal values ​​in the crosstalk signal that are greater than a preset threshold, and determines a first current adjustment parameter corresponding to the maximum signal value based on the maximum signal value and a first corresponding relationship.

[0088] In this embodiment, the crosstalk signal with the maximum signal value causes greater damage to the battery and the electrical appliance, and has the highest probability of being greater than the safe use range of the battery and the electrical appliance. If the current is reduced based only on the average value, the adjusted signal value may still be greater than the safe use range of the battery and the electrical appliance. Therefore, the first current adjustment parameter is determined based on the maximum signal value to ensure that the adjusted current can effectively reduce the signal value so that it will not be greater than the safe use range of the battery and the electrical appliance.

[0089] If the accumulated time does not reach the preset time, the signal value at the next time point will continue to be detected.

[0090] Step 205: The vehicle controller reduces the current of the battery during use based on the first current adjustment parameter.

[0091] The first current adjustment parameter is also the current reduction value.

[0092] In some embodiments, the vehicle controller detects crosstalk signals on multiple signal lines within the loop and identifies the appliance on the signal line with a signal value greater than a preset threshold as the second appliance. Accordingly, the vehicle controller reduces the battery current during use based on the first current adjustment parameter, including the following implementation: the vehicle controller reduces the current of the second appliance based on the first current adjustment parameter. In other words, reducing the battery current during use is achieved by reducing the current of the second appliance.

[0093] In this embodiment, if the signal value on any signal line is greater than a preset threshold, the current on the signal line may increase, which may cause the current to be greater than the safe operating range of the electrical appliance on the signal line, thereby damaging the electrical appliance; in this embodiment, by reducing the current of the electrical appliance on the signal line with a large signal value, not only can the current of the battery during use be reduced, thereby reducing the signal value of the crosstalk signal, but also the impact of the current reduction on other electrical appliances can be avoided as much as possible.

[0094] Among them, in the case of an abnormal crosstalk signal, it indicates that a fault has occurred in the vehicle's electrical appliances. Therefore, when the target signal value is greater than a preset threshold and the cumulative duration of the signal value greater than the preset threshold reaches a preset duration, the vehicle controller also outputs fault information. The fault information is used to prompt that a fault has occurred in the electrical appliances in the vehicle, resulting in an abnormal crosstalk signal.

[0095] Furthermore, when the target signal value is greater than a preset threshold and the cumulative duration of the signal value greater than the preset threshold reaches a preset duration, the vehicle controller also outputs parking indication information, which is used to prompt the user to stop the car to inspect and repair the electrical appliances in the vehicle; further, the parking indication information also indicates the nearest parking lot or the nearest vehicle maintenance place, so that the user can repair the vehicle in time.

[0096] For example, see Figure 3 , which shows a flow chart of a vehicle battery control method shown in an exemplary embodiment of the present application. In which, during normal driving of the vehicle, the BMS in the vehicle controller continuously detects the crosstalk signal in the battery circuit. Determine whether the signal value at the current time point is greater than the preset threshold value. If not, detect the signal value at the next time point. If so, determine whether the target signal value at the current time point is greater than the preset threshold value. If so, determine whether the cumulative duration of the signal value greater than the preset threshold value reaches the preset duration. If not, the BMS sends an alarm message to the VCU (Vehicle Control Unit), which is used to prompt the user to limit the discharge current of the current to 1A; then detect whether the discharge current is adjusted to 1A. If not, continuously output the alarm message. If so, cancel the output of the alarm message and perform vehicle maintenance. If the cumulative duration of the signal value greater than the preset threshold value reaches the preset duration, the BMS sends a forced current limiting instruction to the VCU to limit the discharge current of the battery to 1A, and finally perform vehicle maintenance.

[0097] In an embodiment of the present application, a crosstalk signal is generated in the battery circuit, and an abnormal crosstalk signal, that is, an excessively large signal value, will damage the battery and the electrical appliances in the circuit; therefore, when the signal value of the crosstalk signal is greater than a preset threshold and the cumulative duration of the signal value greater than the preset threshold reaches a preset duration, the first current adjustment parameter of the battery is determined based on multiple signal values ​​greater than the preset threshold in the crosstalk signal, which not only improves the accuracy of determining the abnormality of the crosstalk signal, but also determines the first current adjustment parameter based on the signal value, thereby improving the pertinence and accuracy of the first current adjustment parameter, and then reducing the current based on the first current adjustment parameter, which not only reduces the signal value of the crosstalk signal, but also improves the accuracy of the current adjustment.
