[0021] Embodiments of the present application are described in detail below, and examples of the embodiments 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 application, and should not be construed as limiting the present application.

[0022] The following describes the BMS addressing method and device according to the embodiments of the present application with reference to the accompanying drawings.

[0023] Figure 1 is a flow chart of a BMS addressing method provided in an embodiment of the present application, such as Figure 1 As shown, the addressing method of the BMS of the embodiment of the present application includes but is not limited to the following steps:

[0024] S101, obtaining the board voltage of the BMS and the device voltage of each slave controlled device in the BMS.

[0025] It is understandable that a battery management system (BMS) is a device or system specifically used to monitor and manage the operating status of a battery pack.

[0026] It should be noted that the executor of the BMS addressing method provided in the embodiment of the present application is an electronic device equipped with a BMS, and the electronic device may be a terminal device. Optionally, the terminal device may be a mobile electronic device or a non-mobile electronic device, which is not specifically limited in the embodiment of the present application.

[0027] In some embodiments, the board voltage in the BMS generally refers to the voltage at the connection between the battery module or battery pack and the BMS mainboard. By powering on the BMS, the main control device of the BMS reads the voltage of the board interface and uses the read voltage as the board voltage of the BMS.

[0028] In some embodiments, the slave device may read its own voltage and transmit the voltage to the master device, so that the master device obtains the device voltage of each slave device.

[0029] Optionally, the board terminal voltage and the device voltage of the slave controlled device may be collected based on the voltage collection device.

[0030] S102, determining the number of slave controlled devices in the BMS.

[0031] In some embodiments, configuration information of the BMS may be obtained, and the number of slave controlled devices may be obtained from the configuration information.

[0032] In some embodiments, the number of device voltages of the received slave-controlled devices may also be determined, and the number may be used as the number of devices of the slave-controlled devices.

[0033] In some embodiments, the number of communication interfaces between the master device and the slave device may also be determined, and the number may be used as the number of devices of the slave device.

[0034] S103, determining address information corresponding to the slave control device based on the board terminal voltage, the device voltage and the number of devices, and sending the address information to the slave control device.

[0035] In some embodiments, the voltage threshold range of each slave control device can be determined based on the board terminal voltage and the number of devices, and it can be determined whether the device voltage of any slave control device is within its corresponding voltage threshold range.

[0036] In some embodiments, the BMS includes a wiring harness structure, which is composed of N resistors to achieve resistance voltage division, so that the voltage input to each slave control device is different. Wherein, N is a natural number greater than 1.

[0037] For example, assuming that the input board voltage is 12V, there are 4 resistors and 4 slave control devices, the voltage threshold received by slave control device 1 is 3V, the voltage threshold received by slave control device 2 is 6V, the voltage threshold received by slave control device 3 is 9V, and the voltage threshold received by slave control device 4 is 12V.

[0038] In some embodiments, the voltage threshold can be determined based on the board voltage and the number of devices. Based on the above example, if the slave device is the first slave device, the voltage threshold corresponding to slave device 1 is 12*1 / 4=3V; if the slave device is the Nth slave device, the voltage threshold corresponding to slave device N is 12*N / 4.

[0039] Since voltage detection may have errors, the final voltage threshold range can be determined based on the voltage threshold and the voltage floating range. The voltage threshold refers to the predicted voltage of the slave controlled device, that is, the predicted voltage of the slave controlled device.

[0040] In some embodiments, in response to whether the device voltage is within its corresponding voltage threshold range, address information corresponding to the voltage threshold range can be determined as address information corresponding to the slave control device, and the address information is sent to the slave control device.

[0041] In some embodiments, when receiving the address information, the slave control device may store the address information to implement addressing of the BMS.

[0042] In some embodiments, a mapping relationship between a voltage threshold range and address information may be established. When it is determined that the device voltage is within the voltage threshold range, the address information corresponding to the slave controlled device may be determined by querying the mapping relationship.

[0043] Continuing with the above example, assume that slave device 1 corresponds to range 1, range 1 corresponds to address 1, slave device 2 corresponds to range 2, range 2 corresponds to address 2, where range 1 is 3±10%V and range 2 is 6±10%V. If the device voltage of slave device 1 is 3.05V and is within range 1, the address information corresponding to slave device 1 is address 1.

[0044] In the BMS addressing method provided in the embodiment of the present application, the board voltage of the BMS and the device voltage of each slave device are obtained, and the number of slave devices is determined. Further, according to the board voltage, the device voltage and the number of devices, the address information corresponding to the slave device can be determined, and the slave device can complete the BMS addressing by storing the address information. In the present application, the slave addressing is performed according to the voltage information, and there is no need to use labels or material numbers to distinguish the slave devices, so as to realize simple and convenient addressing operation, optimize the performance and stability of the BMS, and ensure the normal operation of the BMS.

[0045] Figure 2 is a flow chart of a BMS addressing method provided in an embodiment of the present application, such as Figure 2 As shown, the addressing method of the BMS of the embodiment of the present application includes but is not limited to the following steps:

[0046] S201, obtaining the board terminal voltage of the BMS and the device voltage of each slave controlled device in the BMS.

[0047] In the embodiment of the present application, the implementation method of step S201 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0048] S202, determining the number of slave controlled devices in the BMS.

[0049] In the embodiment of the present application, the implementation method of step S202 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0050] S203: Determine a voltage threshold range corresponding to each slave controlled device based on the board terminal voltage and the number of devices.

[0051] In some embodiments, the board-end voltage may be evenly divided according to the number of slave-controlled devices, and then the predicted voltage of each slave-controlled device may be determined based on the board-end voltage and the number of devices.

[0052] For example, if the board-end voltage is U and the number of devices is N, that is, it includes N slave-controlled devices, then the predicted voltage of the first slave-controlled device is U / N, the predicted voltage of the second slave-controlled device is U*2 / N, the predicted voltage of the third slave-controlled device is U*3 / N, and the predicted voltage of the Nth slave-controlled device is U.

[0053] In some embodiments, since there may be errors in voltage detection, a voltage floating threshold may be determined, and a voltage threshold range may be determined based on the predicted voltage and the floating threshold.

[0054] Taking the above example, assuming that the voltage floating threshold is 10%, indicating that the voltage can fluctuate 10% above or below the predicted voltage, the voltage threshold range corresponding to the first slave control device is U / N±10%, the voltage threshold range corresponding to the second slave control device is U*2 / N±10%, and the voltage threshold range corresponding to the Nth slave control device is U±10%.

[0055] S204 , screening slave controlled devices based on the voltage threshold range and the device voltage, and obtaining a first slave controlled device whose device voltage is within the voltage threshold range.

[0056] In some embodiments, the device voltage being within the voltage threshold range can be used as a screening condition. The screening of slave controlled devices is achieved by determining the voltage threshold range corresponding to each slave controlled device and judging whether its device voltage is within the corresponding voltage threshold range.

[0057] In response to the device voltage being within the voltage threshold range and satisfying the screening condition, the slave device satisfying the screening condition may be used as the first slave device, that is, the slave device whose device voltage is within the voltage threshold range may be used as the first slave device.

[0058] In some embodiments, if the screening condition is not met, that is, in response to the device voltage not being within the voltage threshold range, it is determined that the address information allocation fails, and the second slave device whose device voltage is not within the voltage threshold range is determined.

[0059] In some embodiments, when determining the address information of the second slave device fails, the number of failures in allocating the address information of the second slave device can be obtained, and based on the number of failures and a set number threshold, it is determined whether to read the stored address information from the memory of the second slave device.

[0060] In some embodiments, in response to the number of failures being less than a number threshold, address information stored in the second slave control device is acquired, and the stored address information is sent to the second slave control device.

[0061] In some embodiments, in response to the number of failures being greater than or equal to a number threshold, it is determined that an abnormality occurs in the BMS, and the abnormality is reported.

[0062] S205: Acquire a pre-established mapping relationship between a candidate voltage threshold range and candidate address information.

[0063] S206: Determine address information corresponding to the first slave control device based on the mapping relationship and a voltage threshold range of the device voltage of the first slave control device.

[0064] In some implementations, a mapping relationship between a candidate voltage threshold range and candidate address information can be established in advance. When it is determined that the device voltage is within the voltage threshold range, the mapping relationship can be queried based on the voltage threshold range, and the candidate address information corresponding to the voltage threshold range can be used as the address information corresponding to the first slave control device.

[0065] S207: Send address information to the slave control device.

[0066] In the embodiment of the present application, the implementation method of step S207 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0067] In some embodiments, after sending the address information to the slave device, the slave device stores the address information to complete the addressing. The slave device can store the address information in its own memory so that when the master device address allocation fails, the address information can be read from the memory.

[0068] In the BMS addressing method provided in the embodiment of the present application, the voltage threshold range is determined according to the board voltage and the number of devices, and it is determined whether the device voltage is within the voltage threshold range, so as to determine the address information corresponding to the first slave control device within the voltage threshold range. In the present application, slave control addressing is performed according to voltage information, and there is no need to use labels or material numbers to distinguish the slave control devices, so as to achieve simple and convenient addressing operation, optimize the performance and stability of the BMS, and ensure the normal operation of the BMS.

[0069] Figure 3 is a flow chart of a BMS addressing method provided in an embodiment of the present application, such as Figure 3 As shown, the addressing method of the BMS of the embodiment of the present application includes but is not limited to the following steps:

[0070] S301, after the BMS is powered on, the board-side interface outputs voltage, and the voltage is input to each slave control device through the wiring harness structure of the BMS to divide the voltage.

[0071] S302, reading the voltage of the board-end interface as the board-end voltage.

[0072] S303, each slave control device reads its own voltage value as the device voltage, and sends the device voltage to the master control device.

[0073] For example, Figure 4 Shown is a schematic diagram of the structure of a BMS.

[0074] Figure 4 The slave control devices in the system include slave control 1, slave control 2, slave control 3 and slave control N. Figure 4 The wiring harness structure in includes N resistors, namely R1 to RN. By powering on the BMS, the board-side interface can output voltage, which is input to each slave control device through the wiring harness structure of the BMS to divide the voltage.

[0075] The master device reads the voltage of the board-end interface and uses it as the board-end voltage, while the slave devices read the voltage of the address input port of the slave device as the device voltage. Taking slave 1 as an example, slave 1 can read the voltage between Vin1 and V as the device voltage u1 of slave 1; taking slave 2 as an example, slave 2 can read the voltage between Vin2 and V as the device voltage u2 of slave 2; taking slave 3 as an example, slave 3 can read the voltage between Vin3 and V as the device voltage u3 of slave 3; taking slave N as an example, slave N can read the voltage between VinN and V as the device voltage un of slave N.

[0076] Furthermore, the slave device may send the device voltage to the master device.

[0077] S304, determining the number of slave controlled devices in the BMS.

[0078] In the embodiment of the present application, the implementation method of step S304 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0079] S305 , determining address information corresponding to the slave control device based on the board terminal voltage, the device voltage and the number of devices, and sending the address information to the slave control device.

[0080] In the embodiment of the present application, the implementation method of step S305 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0081] In the BMS addressing method provided in the embodiment of the present application, the master device can read the board voltage of the BMS and receive the device voltage of each slave device, so as to determine the address information corresponding to the slave device according to the board voltage, the device voltage and the number of devices, and the slave device can complete the BMS addressing by storing the address information. In the present application, the slave device is addressed according to the voltage information, and there is no need to distinguish the slave devices by using labels or material numbers, so as to realize a simple and convenient addressing operation, optimize the performance and stability of the BMS, and ensure the normal operation of the BMS.

[0082] Figure 5 The figure shows a flow chart of addressing the slave control devices of the BMS.

[0083] By powering on the BMS, each slave device can read the voltage of its own addressing input port as the device voltage and send the device voltage to the master device. The master device can read the board voltage of the BMS and determine the number of slave devices.

[0084] Further, the predicted voltage of the slave control device is determined according to the board terminal voltage and the number of devices, and the voltage threshold range corresponding to the slave control device is determined according to the predicted voltage. It is judged whether the device voltage is within the corresponding voltage threshold range. If so, the first slave control device whose device voltage is within the voltage threshold range is determined, and the address information corresponding to the first slave control device is determined. By sending the address information to the first slave control device, the first slave control device can store the address information.

[0085] Re-power on the BMS and determine whether the device voltage of each slave control device is within the voltage threshold range. If not, determine the second slave control device whose device voltage is not within the voltage threshold range, determine that the address information allocation of the second slave control device has failed, and record the number of failures in the address information allocation of the second slave control device.

[0086] If the number of failures is less than the number threshold, the second slave device determines the address information stored therein and uses the stored address information to implement addressing. If the number of failures is greater than or equal to the number threshold, it is determined that the BMS is abnormal and the abnormality is reported.

[0087] During the BMS power-on process, if the device voltage of the second slave control device is within the voltage threshold range, the number of failures of the second slave control device is reset to zero, and the device voltage of each slave control device is re-determined whether it is within the voltage threshold range during the next power-on.
