[0002] With the development of battery applications, the number of lithium battery pack solutions on the market has gradually increased. Common battery packs are used to power load devices (such as scooters, power-assisted bicycles, and endurance motors). There are some battery packs with different high and low voltage ranges, but they are generally labeled as batteries with the same voltage. For example, the voltage range of ternary lithium batteries is 29-42V when there are 10 strings, and the voltage range of lithium iron phosphate batteries is 27.5-39.6V when there are 11 strings. These two types of batteries are generally labeled as 36V batteries.

[0069] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0070] The "first" in the name of the "first corresponding relationship" mentioned in the embodiment of the present application is only used as a name identifier and does not represent the first in order. The same rule applies to "second", "third", etc.

[0071] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions.

[0072] At present, since the battery output on the market is basically a battery cell + protection board solution, the protection board has built-in short-circuit + overcurrent protection, and the output voltage varies according to the number of battery cells connected in series. The single-cell voltage range of the ternary lithium battery is 3.4~4.2V, and the output voltage range of the ternary lithium battery pack is (3.4~4.2V)*N (N is the number of battery cells connected in series). The single-cell voltage of the lithium iron phosphate battery is generally 3.2~3.6V, and the output voltage range of the lithium iron phosphate battery pack is (3.2~3.6V)*N (N is the number of battery cells connected in series). Therefore, when there are 10 ternary lithium batteries in series, the voltage range is 29~42V, and when there are 11 lithium iron phosphate batteries in series, the voltage range is 27.5~39.6V. These two types of batteries are generally labeled as 36V batteries. Therefore, when the user applies the battery pack to a load device, such as Figure 1 As shown, battery pack 1 representing a ternary lithium battery and battery pack 2 representing a lithium iron phosphate battery may be used interchangeably, but since the actual voltage ranges of the two batteries are different and the output voltage of the battery cannot be limited, overvoltage burning or undervoltage abnormalities may occur in the load equipment.

[0073] In the embodiment of the present application, by connecting the battery pack to the interface device, the voltage of the battery pack obtains the rated voltage set by the output and the type of load device through the interface device, so that a group of battery packs can adapt to a variety of load devices through the interface device to avoid damage to the load device or battery. In specific implementation, the method may include, for example: when the identification module identifies the battery pack as the target battery pack, the conversion device module is turned on through the identification module through a specific interface, wherein the conversion device module is a detachable device with a step-down circuit; the output voltage of the battery pack is converted to the rated voltage through the conversion device module; the rated voltage fed back by the conversion device module is received through the identification module, and the load device type corresponding to the rated voltage is matched according to the corresponding relationship between the voltage and the load; finally, the load device type is transmitted to the Bluetooth module through the identification module, and the load device type is transmitted to the host computer through the Bluetooth module.

[0074] It can be seen that the method provided by the implementation of this application can use the conversion device module to convert the voltage of the battery pack into the rated voltage by stepping down, and then use the identification module to obtain the load device type matched by the current battery pack output voltage according to the correspondence between the voltage and the load device type, and then transmit the matched load device type to the host computer through the Bluetooth module to inform the user, so as to avoid damage to the load device or battery. At the same time, the conversion device module can also make a group of battery packs adapt to multiple load devices. And the rated voltage output by the conversion device module can protect the stability of the load device power supply system.

[0075] To facilitate understanding of the specific implementation of a battery pack load matching method provided in an embodiment of the present application, it will be described below with reference to the accompanying drawings.

[0076] It should be noted that the subject implementing the battery pack load matching method may be an interface device provided in the embodiment of the present application, and the interface may be carried in an electronic device or a functional module of an electronic device. The electronic device in the embodiment of the present application may be any device capable of implementing the battery pack load matching method in the embodiment of the present application, such as an Internet of Things (IoT) device.

[0077] Figure 2 A flow chart of a battery pack load matching method provided in an embodiment of the present application is provided. The method can be applied to an interface device, which can be, for example, Figure 3 The interface device 300 shown, or the interface device can also be integrated into Figure 5 Functional modules in the electronic device 500 are shown.

[0078] like Figure 2As shown, the method is applied to an interface device, the interface device includes an identification module, a Bluetooth module and a conversion device module, the interface device is connected to a battery pack, and the method includes the following S201-S204:

[0079] S201: When the identification module identifies the battery pack as a target battery pack, the conversion device module is turned on through a specific interface by the identification module, and the conversion device module is a detachable device having a step-down circuit.

[0080] In order to obtain the type of load device that matches the output voltage of the battery pack, first connect the interface device to the battery pack, and then turn on the conversion device module through the identification module via a specific interface; convert the output voltage of the battery pack into the rated voltage through the conversion device module; receive the rated voltage fed back by the conversion device module through the identification module, and match the load device type corresponding to the rated voltage according to the corresponding relationship between the voltage and the load; finally, transmit the load device type to the Bluetooth module through the identification module, and transmit the load device type to the host computer through the Bluetooth module, that is, the user can know the type of load device that the battery pack can currently load through the host computer, thereby avoiding direct access to the load device and causing damage to the load power system. Therefore, the embodiment of the present application turns on the conversion device module in the interface device through S201, making preliminary preparations for the subsequent conversion of the output voltage of the battery pack into the rated voltage.

[0081] As an example, before executing S201, the process further includes: the identification module identifies whether the battery pack is a target battery pack, which may specifically include: reading the battery status information of the battery pack from the battery pack according to the Controller Area Network (CAN) protocol through the identification module; if the battery pack category in the battery status information is the battery pack category stored by the identification module, then identifying the battery pack as a target battery pack through the identification module. That is, when the connected battery pack is the target battery pack, the interface device in the embodiment of the present application performs the load matching operation.

[0082] Since the conversion device module is a detachable and replaceable device, the identification module and the conversion device module are connected by a specific interface. When the identification module identifies the battery pack as the target battery pack, the identification module will turn on the conversion device module through the specific interface to perform subsequent voltage conversion operations. Similarly, the interface device also provides the function of turning on the battery.

[0083] In addition, after the battery pack is identified as the target battery pack by the identification module in the embodiment of the present application, the battery status information of the battery pack will be transmitted to the host computer through the Bluetooth module, where the host computer includes a mobile phone, a computer, an industrial computer, etc., so that the user can view the battery status of the currently connected battery pack through the host computer, such as the current battery pack power, so as to monitor and control the status of the battery pack.

[0084] The interface device in the embodiment of the present application also includes a display module, that is, after the identification module reads the battery status information of the battery pack from the battery pack according to the CAN protocol, the battery power information is transmitted to the display module through the identification module, and the battery power of the battery pack can be displayed in real time through the display module, which is also convenient for batch control of the power status of the load equipment. The display module may include a display panel of a light emitting diode (LED) or a liquid crystal display (LCD), and the specific style is not specifically limited here.

[0085] The interface device in the embodiment of the present application also includes an indication module, which transmits interface device startup information to the indication module through the identification module, and indicates that the interface device is turned on through the indication module. When the indication module is a physical device, the method of indicating that the interface device is turned on may include lighting a light, etc., and when the indication module is a virtual module on the display module, the method of indicating that the interface device is turned on may include displaying words or patterns, etc., which are not specifically limited here.

[0086] S202: Convert the output voltage of the battery pack into a rated voltage through a conversion device module.

[0087] The conversion device module of the interface device in the embodiment of the present application is a detachable device with a step-down circuit, that is, different conversion device modules have different step-down circuits. When the output voltage of the battery pack needs to be set to 12V, the conversion device module containing a step-down circuit of 12V can be used as the conversion device module in the interface device. Similarly, when the output voltage of the battery pack needs to be set to 24V, the conversion device module containing a step-down circuit of 24V can be used as the conversion device module in the interface device. Therefore, in the embodiment of the present application, the output voltage of the battery pack can be converted to a predetermined rated voltage through the conversion device module of the interface device. In this process, the voltage of the battery pack is a constant voltage output, which can protect the stability of the power supply system of the back-end load equipment, thereby avoiding damage to the load power system caused by the user's arbitrary replacement of the battery pack.

[0088] Since the same battery can output a variety of voltages by replacing the conversion device module, the conversion device module can also be used to realize that the same battery pack can supply power to a variety of load devices.

[0089] S203: receiving the rated voltage fed back by the conversion device module through the identification module, and matching the load device type corresponding to the rated voltage according to the corresponding relationship between the voltage and the load.

[0090] As an example, S203 may include: after receiving the rated voltage fed back by the conversion device module through the identification module, matching the identification information of the conversion device module through the identification module according to the rated voltage and a first correspondence, wherein the first correspondence is the correspondence between the voltage value and the identification information of the conversion device module stored in the identification module; and then matching the load device type through the identification module according to the identification information and a second correspondence, wherein the second correspondence is the correspondence between the identification information of the conversion device module and the load device type stored in the identification module.

[0091] Among them, the process of storing the correspondence between voltage and load by the identification module includes: receiving the voltage value and identification information of the conversion device module fed back by the conversion device module through the identification module; storing the correspondence between the voltage value and the identification information as a first correspondence through the identification module; transmitting the identification information to the Bluetooth module through the identification module, and transmitting the identification information to the host computer through the Bluetooth module; receiving the load device type fed back by the host computer and transmitted by the Bluetooth module through the identification module; finally, storing the correspondence between the identification information and the load device type as a second correspondence through the identification module. For example, when the voltage value output by the step-down circuit in the conversion device module A is 0.95V, the identification information A of the conversion device module A and the voltage value 0.95V will be transmitted to the identification module. At this time, the identification module stores the correspondence between the voltage value 0.95V and the identification information A to obtain a first correspondence; the identification module subsequently transmits the identification information A to the Bluetooth module, and transmits the identification information A to the host computer through the Bluetooth module, so that the user can input the corresponding load device type in the host computer according to the identification information A, for example, define the conversion device module A corresponding to the scooter type; after the host computer transmits the defined load device type to the identification module through the Bluetooth module, the identification module stores the correspondence between the identification information A and the scooter type to obtain a second correspondence. It should be noted that, in addition to pre-inputting the definition and storage through the host computer, the method of storing the voltage and load correspondence in the above identification module can also directly pre-set the voltage and load correspondence in the identification module, which is not limited here.

[0092] In this process, by setting the corresponding relationship between voltage and load, the identification module in the interface device can obtain the type of load device that can match the current output voltage of the battery pack, so that subsequent users can access the corresponding load device.

[0093] S204: transmitting the load device type to the Bluetooth module through the identification module, and transmitting the load device type to the host computer through the Bluetooth module.

[0094] Finally, the load device type is transmitted to the Bluetooth module through the identification module, and the load device type is transmitted to the host computer through the Bluetooth module to inform the user of the load device type that the current battery pack can be connected to, so as to avoid damage to the load device.

[0095] In addition, the interface device in the embodiment of the present application also includes an operation module. If the operation module indicates a closed state, the operation module transmits the closing information to the identification module, and the conversion device module is closed by the identification module. That is, the operation module is used to close the conversion device module, so that when the battery pack is not in use, the output of the battery pack can be closed, so as not to waste the resources of the battery pack. The operation module can be a physical device such as a button or a knob, or a virtual module such as a virtual button on the display module, which is not limited here.

[0096] It can be seen that after the conversion device module of the embodiment of the present application converts the voltage of the battery pack into the rated voltage by stepping down, the identification module can be used to obtain the load device type matched by the current battery pack output voltage according to the correspondence between the voltage and the load device type, and then the matched load device type is transmitted to the host computer through the Bluetooth module to inform the user, so as to avoid damage to the load device or battery. At the same time, the conversion device module can also make a group of battery packs adapt to multiple load devices. And the rated voltage output by the conversion device module can protect the stability of the load device power supply system.

[0097] The system in the embodiment of the present application can be seen, for example, Figure 3 The interface device 300 shown is connected to the battery pack. The interface device 300 may include, for example: an identification module 301, a conversion device module 302 and a Bluetooth module 303.

[0098] The identification module 301 is used to identify the battery pack as a target battery pack and activate the conversion device module 302 via a specific interface;

[0099] The conversion device module 302 is used to convert the output voltage of the battery pack into a rated voltage, and transmit the rated voltage to the identification module 301 through a specific interface. The conversion device module 302 is a detachable device with a step-down circuit;

[0100] The identification module 301 is also used to determine the load device type corresponding to the rated voltage according to the corresponding relationship between the voltage and the load, and transmit the load device type to the Bluetooth module 303 through a signal;

[0101] The Bluetooth module 303 is used to transmit the load device type to the host computer.

[0102] Depend on Figure 3It can be seen that since the interface device 300 is connected to the battery pack, that is, the identification module 301 in the interface device 300 can identify the battery pack when the battery pack is connected. The specific identification process is that the identification module 301 reads the battery status information of the battery pack from the battery pack according to the CAN protocol; if the battery pack category in the battery status information is the battery pack category stored by the identification module 301, the identification module 301 identifies the battery pack as a target battery pack. After the battery pack is identified as a target battery pack, the conversion device module 302 can be turned on through the specific interface by the identification module 301. After the voltage reduction process, the conversion device module 302 will transmit the fed-back rated voltage to the identification module 301 through a specific interface. The identification module 301 will then match the load device type corresponding to the rated voltage according to the corresponding relationship between the voltage and the load. Finally, since the identification module 301 and the Bluetooth module 303 transmit information through signals, the identification module 301 can transmit the load device type to the Bluetooth module 303 through signals. Subsequently, the Bluetooth module 303 transmits the load device type to the host computer wirelessly so that the user can know the device type that the current battery pack can load match to avoid damage to the load device, wherein the host computer includes a mobile phone, a computer, an industrial computer, etc.

[0103] Among them, the conversion device module 302 is a detachable device with a step-down circuit. Therefore, after the conversion device module 302 is turned on, the output voltage of the battery pack will be converted into a rated voltage. Different conversion device modules 302 correspond to different step-down circuits. Therefore, different conversion device modules 302 can convert the output rated voltage to different levels, such as 12V, 24V, 36V, etc.

[0104] The voltage-load correspondence stored in the identification module 301 can be obtained through a preset program or customized through manual input via Bluetooth communication. The specific method of obtaining the voltage-load correspondence can be as shown in the above embodiment and will not be described in detail here.

[0105] The interface device 300 further includes a display module 304 for receiving and displaying the battery power information transmitted by the identification module 301. That is, after obtaining the battery status information, the identification module 301 can transmit the battery power information in the battery status information to the display module 304 via a signal, and the interface device 300 can display the power of the battery pack. Similarly, after obtaining the battery status information, the identification module 301 can also transmit the battery status information to the Bluetooth module 303 via a signal, and the Bluetooth module 303 subsequently transmits the load device type to the host computer via wireless so that the user can know the current status information of the battery pack.

[0106] The interface device 300 further includes an operation module 305, which is used to transmit shutdown information to the identification module 301 through a signal when indicating a shutdown state, so that the identification module 301 can subsequently shut down the conversion device module 302 through a specific interface. Therefore, the operation module 305 in the interface device 300 can realize the function of shutting down the output of the battery pack to avoid wasting resources.

[0107] The interface device 300 further includes an indication module 306, which is used to receive the interface device activation information transmitted by the identification module 301 through a signal, and indicate that the interface device 300 has been activated according to the interface device activation information. When the indication module 306 is a physical device, the method of indicating that the interface device has been activated may include lighting a light, etc., and when the indication module 306 is a virtual module on the display module 304, the method of indicating that the interface device has been activated may include displaying words or displaying patterns, etc., which are not specifically limited here.

[0108] The interface device 300 proposed in the embodiment of the present application can convert the battery pack output voltage into a specific rated voltage and obtain the load device type corresponding to the rated voltage. The user can know the load device type that the battery pack can currently connect to through the interface device 300 to avoid damage to the load device or the battery pack. The interface device 300 can change the output voltage of the same battery pack by replacing the conversion device module 302 therein, so that the same battery pack can be connected to multiple load device types.

[0109] In order to make the method provided in the embodiment of the present application clearer and easier to understand, Figure 4 This method is applied to Figure 3 A specific example of the interface device 300 is shown for description.

[0110] like Figure 4 As shown, in this implementation, the interface device 300 is connected to the battery pack, and may include, for example:

[0111] S401: the identification module 301 reads the battery status information of the battery pack from the battery pack according to the CAN protocol.

[0112] After the battery pack is connected to the interface device 300, since the interface device 300 in the embodiment of the present application only performs voltage conversion operations on specific types of battery packs, the identification module will directly communicate with the battery according to the CAN protocol to read the battery status information of the battery pack, so as to make subsequent judgments based on the battery status information.

[0113] S402: The identification module 301 determines that the battery group is a target battery group if the battery group category in the battery status information is a stored battery group category.

[0114] When the identification module 301 determines that the battery pack category in the battery status information is the stored battery pack category, it can be determined that the battery pack is the target battery pack, and the voltage conversion function can be performed subsequently.

[0115] S403: The identification module 301 transmits the interface device activation information to the indication module 306, and the indication module 306 indicates that the interface device 300 has been activated.

[0116] When the identification module 301 determines that the battery pack is the target battery pack, it means that the main voltage conversion function of the interface device 300 can be used, so it is necessary to indicate that the interface device 300 has been turned on through the indication module. The specific process is that after the identification module 301 transmits the interface device turn-on information to the indication module 306, the indication module 306 indicates that the interface device 300 has been turned on according to the interface device turn-on information. The setting of the indication module 306 in the embodiment of the present application can be a physical device, such as a light, and the corresponding way to indicate that the interface device 300 has been turned on can be to turn on the light; it can also be a virtual device, such as a virtual module in the display module 304, displaying the word "on", etc., which is not specifically limited here.

[0117] S404: the identification module 301 transmits the battery status information to the Bluetooth module 303, and the Bluetooth module 303 transmits the battery status information to the host computer.

[0118] After the interface device 300 works normally, the identification module 301 needs to transmit the battery status information to the Bluetooth module 303, and then the Bluetooth module 303 transmits the battery status information to the host computer, so that the user can know the current status of the connected battery pack through the host computer, thereby realizing the function of battery pack status monitoring. Among them, the host computer includes a mobile phone, a computer, an industrial computer, etc.

[0119] S405: the identification module 301 transmits the battery power information in the battery status information to the display module 304, and the display module 304 displays the power of the battery pack in real time.

[0120] At the same time, the identification module 301 transmits the battery power information in the battery status information to the display module 304. After receiving the battery power information, the display module 304 can display the power of the battery pack in real time, which is also convenient for batch control of the power status of the load equipment.

[0121] S406: The identification module 301 turns on the conversion device module 302 via a specific interface, wherein the conversion device module 302 is a detachable device having a voltage reduction circuit.

[0122] Since the conversion device module 302 is a detachable device that is easily replaced, the identification module 301 and the conversion device module 302 are connected using a specific interface. When the conversion device module 302 needs to be turned on, the identification module 301 needs to turn on the conversion device module 302 through the specific interface.

[0123] S407: The conversion device module 302 converts the output voltage of the battery pack into a rated voltage.

[0124] Since the conversion device module 302 has a step-down circuit, the output voltage of the battery pack can be converted to the required rated voltage, thereby not only avoiding damage to the load device, but also realizing the function of the same battery pack supplying power to multiple load devices. Since different conversion device modules 302 correspond to different step-down circuits, different conversion device modules 302 can convert the output voltage to different rated voltages, such as 12V, 24V, 36V, etc.

[0125] S408: The identification module 301 receives the rated voltage fed back by the conversion device module 302, and matches the load device type corresponding to the rated voltage according to the corresponding relationship between the voltage and the load.

[0126] In order to obtain the load device that can match the output voltage, the conversion device module 302 needs to feed back the converted rated voltage to the identification module 301 through a specific interface, and the identification module 301 can match the load device type corresponding to the rated voltage according to the voltage-load correspondence. The matching process of the identification module 301 may include: first, the identification module 301 matches the identification information of the conversion device module according to the rated voltage and the first correspondence, wherein the first correspondence is the correspondence between the voltage value and the identification information of the conversion device module stored in the identification module 301; and then, the identification module 301 matches the load device type according to the identification information and the second correspondence, wherein the second correspondence is the correspondence between the identification information of the conversion device module and the load device type stored in the identification module.

[0127] Among them, the process of storing the above-mentioned voltage-load correspondence in the identification module 301 can be to directly input the preset voltage-load correspondence into the program of the identification module 301, or the user can input the voltage-load correspondence into the identification module 301 for storage in advance through communication between the host computer and the interface device 300. The specific process can be, for example, as shown in the above-mentioned embodiment, which will not be repeated here.

[0128] S409: the identification module 301 transmits the load device type to the Bluetooth module 303, and the Bluetooth module 303 transmits the load device type to the host computer.

[0129] After the identification module 301 obtains the corresponding load device type, it first needs to transmit the load device type to the Bluetooth module 303, and then the Bluetooth module 303 transmits the load device type to the host computer, so that the user can know through the host computer the load device type that the voltage output by the current battery pack can match, thereby avoiding damage to the load device or battery.

[0130] S410 : When the operation module 305 indicates a closed state, the operation module 305 transmits a closing message to the identification module 301 , and the identification module 301 closes the conversion device module 302 .

[0131] Finally, when the user wants to turn off the output of the battery pack, the user can manipulate the operating module 305 in the interface device 300 to indicate the off state. When the operating module 305 indicates the off state, the operating module 305 will transmit the off information to the identification module 301. The identification module 301 agrees to turn off the conversion device module 302 through a specific interface, that is, the output function of the battery pack can be turned off through the operating module 305 to avoid wasting resources.

[0132] This embodiment provides a method for matching the load of a battery pack. The output voltage of the battery pack can be stepped down by the conversion device module 302 to output a specific rated voltage, and the preset voltage and load correspondence stored in the identification module 301 can directly obtain the load device type currently matched by the battery pack, and then the matched load device type can be transmitted to the host computer according to the Bluetooth module 303 to inform the user, thereby avoiding the situation where the load device or battery is damaged. At the same time, since the conversion device module 302 is a detachable device, by replacing different conversion device modules 302, the same battery pack can output different rated voltage values, thereby matching different load device types. In addition, the embodiment of the present application can also monitor the battery status and display the battery power in real time through the identification module 301, the Bluetooth module 303 and the display module 304, so as to manage the power consumption status of the load device, and the conversion device module 302 can also be turned on and off by the identification module 301 and the operation module 305, thereby avoiding the waste of battery resources.
