[0002] As charging technology becomes more and more mature, the development of electric vehicles has also advanced by leaps and bounds. In order to meet the interchangeability of battery packs, the dimensions and technical status of each battery pack are generally kept consistent. However, since the position of the battery pack is not fixed, when the battery pack is updated, the diagnostic address of the battery pack also changes accordingly.

However, this method requires the cooperation of the battery management system, which increases the workload of the battery management system. If the battery management system is to be improved, the cost will be greatly increased. Moreover, the diagnostic accuracy cannot be guaranteed by improving the battery management system alone.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following describes a method and device for determining a diagnostic address, a storage medium, a management system, and a vehicle according to an embodiment of the present invention with reference to the accompanying drawings.

[0033] like Figure 1 As shown, the vehicle of the present invention includes n battery packs, each of which is provided with a corresponding controller, wherein the first battery pack includes BMU (Battery Management Unit, battery pack controller) 1, the second battery pack includes BMU2, ..., and the nth battery pack includes BMUn. The battery pack is connected to the external diagnostic equipment through the vehicle wiring harness, and resistors with different resistance values ​​are connected between the battery pack controller and the vehicle wiring harness, which are the first resistor R1, the second resistor R2, ..., and the nth resistor Rn. Among them, the resistance values ​​of different resistors are different, and the first resistor R1 can be set corresponding to the first battery placement position, the second resistor R2 can be set corresponding to the second battery placement position, and so on. Each battery placement position is provided with a resistor, and the battery placement position is used to place the battery, and different diagnostic addresses correspond to different resistors one by one.

[0034] Figure 2 It is a flow chart of a method for determining a diagnostic address in one embodiment of the present invention.

[0035] like Figure 2 As shown, the present invention proposes a method for determining a diagnostic address, which includes the following steps:

[0036] S10, within the preset time after the battery pack controller is powered on, obtain the resistance value of the resistor connected between the battery pack controller and the vehicle wiring harness.

[0037] Specifically, the battery pack controller is set on the battery pack. After the battery pack is replaced on the vehicle, the resistance value of the resistor between the battery pack controller and the wiring harness of the whole vehicle can be detected. Specifically, Ohm's law can be used to detect the current and voltage passing through the corresponding resistor, and then the corresponding resistance can be calculated. Of course, this embodiment can also detect the resistance value of the resistor in other ways, and its specific detection method is not limited. In this embodiment, the position specification of the vehicle for placing the battery pack can be a standardized design to improve the compatibility between battery packs of different brands. Of course, the size specifications of each battery pack are also the same. In addition, this embodiment can be limited to detecting the resistance value of the corresponding resistor only after the battery pack controller is powered on for a preset time, thereby improving the detection accuracy of the resistance value. Optionally, the preset time is 200 milliseconds. It should be noted that the specific duration of the preset time can be determined based on the difficulty of replacing the battery pack, the response speed, etc., and is not specifically limited here.

[0038] S20, determining a diagnostic address corresponding to the battery pack controller according to the resistance value.

[0039] Specifically, after obtaining the resistance value of the resistor, the position of the battery pack can be determined based on the resistance value, and the corresponding diagnostic address can be started. For example, when it is detected that the current battery pack is placed in the first battery pack placement position, the resistance value of the resistor can be detected to be R1, and the diagnostic address SA1 of the battery pack controller can be started, and the same applies to other diagnostic addresses.

[0040] Of course, in this embodiment, the resistance value corresponding to each position can also be set in advance, and then the range of the resistance value can be standardized. If the obtained resistance value is not within the range, the diagnostic address corresponding to the battery pack controller cannot be determined, which means that the current battery pack is not correctly placed on the corresponding position, or the resistor is faulty, etc. In order to ensure safe operation, the diagnostic service function of the battery pack controller is turned off.

[0041] After determining the diagnostic address, the diagnostic address can be awakened. It should be noted that the battery pack controller includes multiple diagnostic addresses, and the number of diagnostic addresses included can be equal to the number of all resistors. After determining the resistance value, the diagnostic address corresponding to the resistance value can be awakened, so that the diagnostic address can be in a valid state, which is convenient for subsequent use. The specific way to wake up the diagnostic address can be to first turn on the diagnostic service function of the battery pack controller, and then set the diagnostic address to the communication address connecting the battery pack controller and the external diagnostic device, so that the external diagnostic device can perform fault detection on the battery pack controller through the diagnostic address.

[0042] More specifically, if Figure 3 As shown, the resistance of the vehicle harness end resistor is detected within 200 milliseconds after the battery pack controller is powered on, and the resistance value and the resistance value of the first resistor R1, the resistance value of the second resistor R2, ..., the resistance value of the nth resistor Rn are respectively determined. When the resistance value is equal to the resistance value of the first resistor R1, the diagnostic address of the battery pack controller is set to SA1. When the resistance value is equal to the resistance value of the second resistor R2, the diagnostic address of the battery pack controller is set to SA2. When the resistance value is equal to the resistance value of the nth resistor Rn, the diagnostic address of the battery pack controller is set to SAn. After the diagnostic address of the battery pack controller is assigned, the battery pack controller can activate the UDS (Unified Diagnostic Services) diagnostic function. Otherwise, when the resistance value is not equal to the resistance values ​​of all resistors, the battery pack controller can turn off the UDS diagnostic function.

[0043] In summary, the method for determining the diagnostic address of the embodiment of the present invention can reduce the diagnostic difficulty and diagnostic cost of the battery pack controller, and can also accurately identify the battery pack that needs to be diagnosed.

[0044] Furthermore, the second aspect of the present invention provides a computer-readable storage medium on which a diagnostic address determination program is stored. When the determination program is executed by a processor, the method for determining the diagnostic address of any of the above embodiments is implemented.

[0045] The computer-readable storage medium of the embodiment of the present invention can reduce the diagnostic difficulty and diagnostic cost of the battery pack controller by executing the diagnostic address determination program stored thereon through a processor, and can also accurately identify the battery pack that needs to be diagnosed.

[0048] Among them, the acquisition module 401 is used to obtain the resistance value of the resistor connected between the battery pack controller and the vehicle wiring harness within the preset time when the battery pack controller is powered on; the determination module 402 is used to determine the diagnostic address corresponding to the battery pack controller according to the resistance value.

[0049] In some embodiments of the present invention, the determination module 402 is further used to: if the diagnostic address corresponding to the battery pack controller is not determined according to the resistance value, then shut down the diagnostic service function of the battery pack controller.

[0050] In some embodiments of the present invention, the preset time is 200 milliseconds.

[0051] In some embodiments of the present invention, the battery pack controller is disposed in the corresponding battery pack.

[0052] In some embodiments of the present invention, each battery pack has the same size specifications.
