Description

Technical Field

[0001] This invention relates to battery management, and more particularly to a battery management method, battery management device, and storage device for use in mobility aids. Background Technology

[0002] As people's quality of life continues to improve, the quality of life for those with mobility impairments should also be improved. For example, making movement more comfortable while maintaining freedom and autonomy. Assistive devices have emerged as a result, providing effective assistance for people with lower limb disabilities or the elderly, and are simple in structure and easy to use.

[0003] Currently, after the main body of the walking aid device is connected to the battery, the battery directly supplies power to the main body of the walking aid device. This may lead to a mismatch between the battery and the walking aid device, resulting in unstable current output from the battery. This, in turn, affects the unstable motor output power of the walking aid device, which in turn leads to safety hazards and affects the service life of the walking aid device.

[0004] Patent publication number ZL201910163378.6, published on January 3, 2020, discloses an electric bicycle battery management system. The electric bicycle includes a battery and a main power supply line. The system includes a first temperature probe, a second temperature probe, an over-discharge monitoring unit, a charging overcharge prevention control unit, a charger matching detection unit, and a communication unit. This system achieves functions such as temperature acquisition, over-discharge monitoring, charging overcharge prevention, and charger matching detection. Simultaneously, the communication unit uploads battery temperature data, main power supply line temperature data, low battery voltage information, overcharge information, and charger mismatch information to a server, allowing users to monitor the electric bicycle's status in real time. Compared to existing technologies, this invention significantly improves battery utilization, effectively extends battery life, helps reduce safety hazards in electric bicycles, and better meets user and market demands. While this solution achieves good charging control matching, the aforementioned potential mismatch between the battery and the mobility aid still exists. Summary of the Invention

[0005] This invention addresses the current issue of incompatibility between batteries and walking aids, leading to unstable battery output current and consequently unstable motor output power, posing safety hazards and impacting the lifespan of the walking aid. It provides a battery management method, device, and storage device that improves the safety of walking aids by enabling faster response times for the battery management device. This allows compliant batteries to quickly supply power to the walking aid while preventing non-compliant batteries from providing power. It also reduces the risk of malfunctions, sudden stops, or rapid acceleration caused by voltage or current mismatches or instability from non-compliant batteries, thereby enhancing the safety of battery use and ultimately improving the overall safety of walking aids.

[0006] The specific technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a battery management method for a mobility aid, characterized in that it includes the following battery management methods: A1. Obtain the unique serial number corresponding to the battery, the serial number including a first sub-serial number and a second sub-serial number; A2. Determine whether both the first sub-sequence number and the second sub-sequence number are compliant; A3. In step A2 above, if both the first sub-serial number and the second sub-serial number are compliant, then the battery is valid and the battery is allowed to supply power to the main body of the mobility aid device; A4. In step A2 above, if the first sub-serial number and the second sub-serial number are not compliant at the same time, the battery is allowed to supply power to the main body of the walking aid device within a first threshold time, or the battery is prohibited from supplying power to the main body of the walking aid device.

[0007] By ensuring that both the first and second sub-serial numbers are compliant, the battery is deemed legitimate, allowing it to supply power to the main body of the mobility aid. This enables a faster response time for the battery management device, ensuring that compliant batteries can quickly power the main body of the mobility aid. Conversely, by allowing or prohibiting the battery from supplying power to the main body of the mobility aid within a first threshold time when the first and second sub-serial numbers are not compliant simultaneously, the battery supplying power to the main body of the mobility aid is made more compliant with the operating standards of the mobility aid. This reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatches or instability, thus improving battery safety and consequently, the safety of the mobility aid. Furthermore, because compliant batteries have more stable output current, the likelihood of the main body's motor generating extra heat due to current fluctuations is lower, slowing down the aging of the motor's insulation materials. The likelihood of damage to components in the main body's controller due to frequent voltage fluctuations is also lower. Additionally, the possibility of the battery experiencing partial or incomplete charging is reduced, minimizing the possibility of limiting the mobility aid's range.

[0008] Preferably, the above A4 step includes the following management methods: B1. Determine whether the first sub-sequence number is compliant; B2. If the first sub-serial number is compliant, and the second sub-serial number is non-compliant, the battery is allowed to supply power to the main body of the walking aid device within a first threshold time, or the battery is prohibited from supplying power to the main body of the walking aid device. B3. If the first sub-serial number is non-compliant, the battery is prohibited from supplying power to the main body of the walking aid device.

[0009] By determining whether the first sub-serial number is compliant when the first and second sub-serial numbers are not simultaneously compliant, and prohibiting the battery from supplying power to the main body of the walking aid device when the first sub-serial number is non-compliant, the step of re-determining whether the second sub-serial number is compliant can be eliminated, reducing the calculation steps of the battery management device and improving its calculation efficiency. By allowing the battery to supply power to the main body of the walking aid device within a first threshold time when the first sub-serial number is compliant and the second sub-serial number is non-compliant, or prohibiting the battery from supplying power to the main body of the walking aid device, the battery supplying power to the main body of the walking aid device can be made more in line with the operating standards of the walking aid device. This reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery during operation, thereby improving the safety of battery use and thus the safety of walking aid device use.

[0010] Preferably, after step B2 above, the following management method is also included: C1. Determine whether the battery is being connected for the first time; C2. In step C1 above, if the battery is being connected for the first time, the battery is allowed to supply power to the main body of the walking aid device within a first threshold time. C3. In step C1 above, if the battery is not being connected for the first time, then the battery is prohibited from supplying power to the main body of the walking aid device.

[0011] By determining whether the battery is being connected for the first time when the first sub-serial number is compliant and the second sub-serial number is non-compliant, and allowing the battery to supply power to the main body of the walking aid device within a first threshold time when it is determined that the battery is being connected for the first time, the walking aid device can operate briefly, which facilitates the debugging and other operations of the walking aid device.

[0012] Preferably, step C1 above includes the following management methods: D1. After obtaining the serial number of the battery each time, store the first sub-serial number; D2. After obtaining the serial number of the battery again, determine whether the first sub-serial number of the current battery matches the first sub-serial number that has been stored; D3. In step D2 above, if the first sub-serial number of the current battery matches the first sub-serial number that has been stored, then the battery is not being connected for the first time. D4. In step D2 above, if the first sub-serial number of the current battery does not match the stored first sub-serial number, then the battery is being connected for the first time.

[0013] Preferably, after step C2 above, a first error message is sent after the first threshold time to prevent the battery from supplying power to the main body of the walking aid device; after step C3 above, the first error message is sent to prevent the battery from supplying power to the main body of the walking aid device. By sending the first error message after the first threshold time following "determining that the battery is being connected for the first time" to prevent the battery from supplying power to the main body of the walking aid device, and by sending the first error message after "determining that the battery is not being connected for the first time" to prevent the battery from supplying power to the main body of the walking aid device, a prompt can be provided to the user. Furthermore, this ensures that the battery supplying power to the main body of the walking aid device is more in line with the device's operating standards, reducing the risk of malfunctions, sudden stops, or rapid accelerations during operation due to voltage or current mismatch or instability caused by the battery. This improves battery safety and, consequently, the safety of the walking aid device.

[0014] Preferably, after step B3 above, a first error message is sent to prohibit the battery from supplying power to the main body of the walking aid device. By sending the first error message after "judging that the first sub-serial number is non-compliant," the battery is prohibited from supplying power to the main body of the walking aid device. This serves as a reminder to the user and ensures that the battery supplying power to the main body of the walking aid device is more in line with the device's operating standards. This reduces the risk of malfunctions, sudden stops, or rapid accelerations during operation caused by voltage or current mismatch or instability provided by the battery, thereby improving battery safety and ultimately enhancing the safety of the walking aid device.

[0015] Preferably, the following battery management methods are also included: E1. If the power supply signal from the battery is not received for N consecutive times, it is determined to be a communication timeout, where N≥10; E2. Determine whether the serial number of the battery can be obtained; E3. In step E2 above, if the serial number of the battery cannot be obtained, a first error message is sent to prevent the battery from supplying power to the main body of the walking aid device; E4. In step E2 above, if the serial number of the battery is obtained and it is determined that the battery is invalid, a first error message is sent to prevent the battery from supplying power to the main body of the walking aid device; E5. In step E2 above, if the serial number of the battery is obtained and the battery is determined to be valid, then a second error message is sent.

[0016] By sending a first error message when a communication timeout occurs and the battery serial number cannot be obtained, thus prohibiting the battery from supplying power to the main body of the walking aid, the system ensures that the battery supplying the main body of the walking aid is more in line with the operating standards of the walking aid. This reduces the risk of malfunctions, sudden stops, or rapid acceleration caused by voltage or current mismatch or instability provided by the battery during operation, thereby improving battery safety and the overall safety of the walking aid. Similarly, by sending a first error message when a communication timeout occurs and the battery is deemed invalid, again prohibiting the battery from supplying power to the main body of the walking aid, the system ensures that the battery supplying the main body of the walking aid is more in line with the operating standards of the walking aid. This reduces the risk of malfunctions, sudden stops, or rapid acceleration caused by voltage or current mismatch or instability provided by the battery during operation, thereby improving battery safety and the overall safety of the walking aid. Finally, by sending a second error message when a communication timeout occurs but the battery is deemed valid, the system serves as a notification to the user.

[0017] Preferably, after the E5 step described above, the error is cancelled after a second threshold time, and the power supply signal and serial number of the battery are reacquired. By cancelling the error after the second threshold time and reacquiring the battery's power supply signal and serial number, the battery can promptly resume supplying power to the main body of the walking aid device after communication is restored, thereby improving the reliability of the walking aid device.

[0018] Another objective of this invention application is to provide a battery management device for a walking aid, characterized in that it includes a communication circuit and a processor, and employs the battery management method for a walking aid described in one of the above-mentioned technical solutions. The communication circuit is used to acquire the serial number of the battery, the serial number including a first sub-serial number and a second sub-serial number. The processor is connected to the communication circuit and is used to determine whether the first sub-serial number and the second sub-serial number are simultaneously compliant. If both the first sub-serial number and the second sub-serial number are compliant, the battery is valid, allowing the battery to supply power to the main body of the walking aid. If the first sub-serial number and the second sub-serial number are not simultaneously compliant, the battery is allowed to supply power to the main body of the walking aid for a first threshold time period, or the battery is prohibited from supplying power to the main body of the walking aid.

[0019] By allowing or prohibiting the battery from supplying power to the main body of the walking aid device within a first threshold time when the first and second sub-serial numbers are not simultaneously compliant, the battery supplying power to the main body of the walking aid device can be made more compliant with the operating standards of the walking aid device. This reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery, thus improving the safety of battery use and consequently the safety of the walking aid device. Furthermore, because the output current of a compliant battery is more stable, the likelihood of the motor in the main body of the walking aid device generating additional heat due to current fluctuations is lower, which slows down the aging of the motor's insulation materials. The likelihood of damage to components in the controller of the main body of the walking aid device due to frequent voltage fluctuations is also lower. At the same time, the likelihood of the battery experiencing false charges or incomplete charging is also lower, reducing the possibility of limiting the driving range of the walking aid device.

[0020] Another objective of this invention application is to provide a battery storage device for a mobility aid, characterized in that: it stores program data, which can be executed by the mobility aid battery management device described in the above technical solutions to implement the mobility aid battery management method described in one of the above technical solutions.

[0021] The beneficial effects of this invention are as follows: By ensuring that both the first and second sub-serial numbers are compliant, the battery is deemed legitimate, allowing it to supply power to the main body of the mobility aid device. This enables the battery management device to respond quickly, allowing compliant batteries to rapidly supply power to the main body of the mobility aid device. By allowing the battery to supply power to the main body of the mobility aid device within a first threshold time when the first and second sub-serial numbers are not compliant simultaneously, or prohibiting the battery from supplying power to the main body of the mobility aid device, the batteries supplying power to the main body of the mobility aid device are more in line with the operating standards of the mobility aid device. This reduces the risk of malfunctions, sudden stops, or rapid accelerations during operation caused by voltage or current mismatch or instability provided by the battery, thus improving the safety of battery use and consequently the safety of the mobility aid device. Furthermore, because compliant batteries have a more stable output current, the likelihood of the motor in the main body of the mobility aid device generating additional heat due to current fluctuations is lower, slowing down the aging of the motor's insulation materials. The likelihood of damage to components in the controller of the main body of the mobility aid device due to frequent voltage fluctuations is also lower. At the same time, the likelihood of the battery experiencing false charges or incomplete charging is also lower, reducing the possibility of limiting the driving range of the mobility aid device.

[0027] Example 1 Figure 1 In the illustrated embodiment, a battery management method for a mobility aid includes the following battery management approach: A1. Obtain the unique serial number corresponding to the battery, the serial number including a first sub-serial number and a second sub-serial number; in some embodiments, the serial number is the SN (Serial Number) code, and the serial number may include at least one of numbers, letters, and symbols; A2. Determine whether both the first sub-sequence number and the second sub-sequence number are compliant; In some embodiments, the battery management device of the mobility aid has pre-stored the serial numbers of compliant batteries. If the first sub-serial number and the second sub-serial number in the obtained battery serial number both match the first sub-serial number and the second sub-serial number in the pre-stored serial number, then it is determined to be compliant. The matching criterion is that every digit and / or letter in the serial number is the same. A3. In step A2 above, if both the first sub-serial number and the second sub-serial number are compliant, then the battery is valid and is allowed to supply power to the main body of the mobility aid device; By ensuring that both the first and second sub-serial numbers are compliant, the battery is deemed valid, allowing the battery to supply power to the main body of the walking aid device. This enables the battery management device to respond quickly, allowing compliant batteries to rapidly supply power to the main body of the walking aid device. In some embodiments, the battery management device is connected to the main body of the walking aid device. When the battery management device is connected to the battery and determines that the battery is valid, it can connect the battery to the main body, thereby enabling the battery to supply power to the main body of the walking aid device. A4. In step A2 above, if the first sub-serial number and the second sub-serial number are not compliant simultaneously, then the battery is allowed to supply power to the main body of the walking aid device within a first threshold time, or the battery is prohibited from supplying power to the main body of the walking aid device. Allowing the battery to supply power to the main body of the walking aid device within the first threshold time, when at least one serial number is compliant, indicates that the battery is still original. This allows users or the factory to use the battery for an emergency distance, after which it is no longer permitted to be used, preventing potential safety hazards if the battery is indeed faulty.

[0028] In some embodiments, the battery management device can prevent the battery from supplying power to the main body of the walking aid by disconnecting the connection with the battery, or the battery management device can remain connected to the battery while preventing the battery from supplying power to the main body of the walking aid by disconnecting the connection with the main body of the walking aid.

[0029] By allowing or prohibiting the battery from supplying power to the main body of the walking aid device within a first threshold time when the first and second sub-serial numbers are not simultaneously compliant, the battery supplying power to the main body of the walking aid device can be made more compliant with the operating standards of the walking aid device. This reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery, thus improving the safety of battery use and consequently the safety of the walking aid device. Furthermore, because the output current of a compliant battery is more stable, the likelihood of the motor in the main body of the walking aid device generating additional heat due to current fluctuations is lower, which slows down the aging of the motor's insulation materials. The likelihood of damage to components in the controller of the main body of the walking aid device due to frequent voltage fluctuations is also lower. At the same time, the likelihood of the battery experiencing false charges or incomplete charging is also lower, reducing the possibility of limiting the driving range of the walking aid device.

[0030] Example 2 Figure 2 In the embodiment shown, Figure 2 This is a schematic diagram of another method flow for the battery management method, battery management device, and storage device of the present invention for mobility aids; including the following battery management methods: A1. Obtain the unique serial number corresponding to the battery. The serial number includes the first sub-serial number and the second sub-serial number.

[0031] In some embodiments, the first sub-serial number may include 8, 16, or 24 digits and / or letters, and the second sub-serial number may include 8, 16, or 24 digits and / or letters. In some embodiments, the first sub-serial number includes a sixteen-bit code, wherein the first to twelfth bits are the battery manufacturer's code, and the thirteenth to sixteenth bits are the production date code.

[0032] In some embodiments, the second sub-serial number includes a 16-bit code. The first bit of the second sub-serial number can be a first sub-feature identification code, which can represent the current processing department of the battery, such as the production department, sales department, or after-sales department. The second bit of the second sub-serial number can be a second sub-feature identification code, which can represent the current processing personnel or sales mode of the battery. The first and second sub-feature identification codes together form a feature identification code. For example, in the first sub-feature identification code, 1-9 represent the production line number, 0 represents the after-sales department, and C represents the sales department. Feature identification code 11 represents the first production line processing personnel on production line 1, 03 represents the third after-sales personnel in the after-sales department, and C3 represents sales through physical stores (or online sales channels 1 and 2).

[0033] In some embodiments, the third to sixth digits of the second sub-serial number may identify the product model code of the walking aid device. The seventh to twelfth digits of the second sub-serial number may identify the production date code of the walking aid device. The thirteenth to sixteenth digits of the second sub-serial number may identify the serial number code of the walking aid device.

[0034] A2. Determine whether the first sub-sequence number and the second sub-sequence number are both compliant.

[0035] A3. In step A2 above, if both the first sub-serial number and the second sub-serial number are compliant, then the battery is valid, allowing the battery to supply power to the main body of the mobility aid device.

[0036] By ensuring that both the first and second sub-serial numbers are compliant, the battery is deemed valid, allowing it to supply power to the main body of the walking aid device. This enables the battery management device to respond quickly, allowing compliant batteries to rapidly supply power to the main body of the walking aid device.

[0037] B1. In step A2 above, if the first sub-sequence number and the second sub-sequence number are not compliant at the same time, then determine whether the first sub-sequence number is compliant. In some embodiments, the battery management device of the mobile device pre-stores a compliant first sub-serial number and a second sub-serial number. If the first sub-serial number in the obtained battery serial number matches the first sub-serial number in the pre-stored serial number, the first sub-serial number is determined to be compliant. The matching criterion is that every number and / or letter in the first sub-serial number is the same.

[0038] B2. In step B1 above, if the first sub-serial number is compliant, then the second sub-serial number is non-compliant. Within the first threshold time, the battery is allowed to supply power to the main body of the walking aid device, or the battery is prohibited from supplying power to the main body of the walking aid device.

[0039] In some embodiments, the first threshold may be 10 minutes, 15 minutes, or 20 minutes, etc.

[0040] B3. In step B1 above, if the first sub-serial number is not compliant, the battery is prohibited from supplying power to the main body of the mobility aid device.

[0041] By determining whether the first sub-serial number is compliant when the first and second sub-serial numbers are not simultaneously compliant, and prohibiting the battery from supplying power to the main body of the walking aid device when the first sub-serial number is non-compliant, the step of re-determining the compliance of the second sub-serial number can be eliminated, reducing the calculation steps of the battery management device and improving its calculation efficiency. Furthermore, by allowing the battery to supply power to the main body of the walking aid device within a first threshold time when the first sub-serial number is compliant and the second sub-serial number is non-compliant, or prohibiting the battery from supplying power to the main body of the walking aid device, the battery supplying power to the main body of the walking aid device can be made more compliant with the operating standards of the walking aid device, reducing the need for battery power supply. The risk of malfunctions, sudden stops, or rapid acceleration in mobility aids due to voltage or current mismatch or instability can be mitigated by improving battery safety, thereby enhancing the safety of mobility aid use. Furthermore, because compliant batteries have a more stable output current, the likelihood of the motor in the main body of the mobility aid generating extra heat due to current fluctuations is lower, which slows down the aging of the motor's insulation materials. The likelihood of damage to components in the controller of the main body of the mobility aid due to frequent voltage fluctuations is also lower. At the same time, the possibility of the battery experiencing false charges or incomplete charging is also lower, reducing the likelihood of limiting the range of the mobility aid.

[0042] Example 3 Figure 3 In the embodiment shown, Figure 3 This is a schematic flowchart of another method of the battery management method, battery management device, and storage device for the mobility aid of the present invention; including the following battery management methods: A1. Obtain the battery's serial number, which includes the first sub-serial number and the second sub-serial number.

[0043] A2. Determine whether the first sub-sequence number and the second sub-sequence number are both compliant.

[0044] A3. In step A2 above, if both the first sub-serial number and the second sub-serial number are compliant, then the battery is valid, allowing the battery to supply power to the main body of the mobility aid device.

[0045] By ensuring that both the first and second sub-serial numbers are compliant, the battery is deemed valid, allowing it to supply power to the main body of the walking aid device. This enables the battery management device to respond quickly, allowing compliant batteries to rapidly supply power to the main body of the walking aid device.

[0046] B1. In step A2 above, if the first sub-serial number and the second sub-serial number are not compliant at the same time, then determine whether the first sub-serial number is compliant.

[0047] C1. In step B1 above, if the first sub-serial number is compliant, then the second sub-serial number is non-compliant. Determine whether the battery is being connected for the first time. C2. In step C1 above, if the battery is being connected for the first time, the battery is allowed to supply power to the main body of the walking aid device within the first threshold time, and a first error message is sent after the first threshold time to prohibit the battery from supplying power to the main body of the walking aid device.

[0048] By determining whether the battery is being connected for the first time when the first sub-serial number is compliant but the second sub-serial number is non-compliant, and if it is determined to be the first time, the battery is allowed to supply power to the main body of the walking aid device for a first threshold time, allowing the walking aid device to operate briefly, thus facilitating debugging and other operations. After the first threshold time, a first error message is sent, prohibiting the battery from supplying power to the main body of the walking aid device. This serves as a reminder to the user and ensures that the battery supplying power to the main body of the walking aid device is more in line with the device's operating standards. This reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery, thereby improving battery safety and ultimately enhancing the safety of the walking aid device.

[0049] C3. In step C1 above, if the battery is not being connected for the first time, send the first error message to prevent the battery from supplying power to the main body of the walking aid device.

[0050] By determining whether the battery is being connected for the first time when the first sub-serial number is compliant but the second sub-serial number is non-compliant, and sending a first error message when the battery is determined not to be connected for the first time, the system prevents the battery from supplying power to the main body of the walking aid device. This reduces the possibility of damage to the main body of the walking aid device caused by repeated unauthorized battery power supply, improves battery management efficiency, and enhances the protection of the main body of the walking aid device. Sending the first error message also serves as a notification to the user.

[0051] B3. In step B1 above, if the first sub-serial number is not compliant, the battery is prohibited from supplying power to the main body of the walking aid device; the first error message is sent to prohibit the battery from supplying power to the main body of the walking aid device.

[0052] By determining whether the first sub-serial number is compliant when the first sub-serial number and the second sub-serial number are not compliant at the same time, and prohibiting the battery from supplying power to the main body of the mobility aid when the first sub-serial number is non-compliant, the step of determining whether the second sub-serial number is compliant can be eliminated, reducing the calculation steps of the battery management device and improving the calculation efficiency of the battery management device.

[0053] In some embodiments, the method for "determining whether the battery is being connected for the first time" includes: D1. After obtaining the battery serial number each time, store the first sub-serial number.

[0054] In some embodiments, the first sub-serial number can be the first half of the serial number, that is, after obtaining the battery's serial number, the first half of the serial number is extracted and saved as the first sub-serial number.

[0055] In other embodiments, the first sub-sequence number can be the first third segment, the first two-thirds segment, etc. of the sequence number.

[0056] D2. After obtaining the battery serial number again, determine whether the current battery's first sub-serial number matches the stored first sub-serial number.

[0057] In some embodiments, the matching criterion is that each digit and / or letter in the current battery's first sub-serial number is the same as a certain stored first sub-serial number.

[0058] D3. In step D2 above, if the current battery's first sub-serial number matches the stored first sub-serial number, then the battery is not being connected for the first time.

[0059] D4. In step D2 above, if the current battery's first sub-serial number does not match the stored first sub-serial number, then the battery is being connected for the first time.

[0060] In some embodiments, the battery management method for the mobility aid device further includes (see steps E1 to E5): E1. If the battery power supply signal is not received for N consecutive times, it is judged as a communication timeout, N≥10; N is a natural number, such as 10, 15, 20, etc.

[0061] E2. Determine if the battery serial number can be obtained.

[0062] E3. In step E2 above, if the battery serial number cannot be obtained, the first error message is sent to prevent the battery from supplying power to the main body of the walking aid device.

[0063] If the battery serial number cannot be obtained when a communication timeout is detected, a first error message is sent to prevent the battery from supplying power to the main body of the walking aid device. This ensures that the battery supplying power to the main body of the walking aid device is more in line with the device's operating standards. It also reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery, thereby improving the safety of battery use and ultimately enhancing the safety of the walking aid device.

[0064] E4. In step E2 above, if the battery serial number is obtained and the battery is determined to be invalid, the first error message is sent to prevent the battery from supplying power to the main body of the walking aid device.

[0065] By sending a first error message when a communication timeout is detected and the battery is deemed invalid, the system prohibits the battery from supplying power to the main body of the walking aid device. This ensures that the battery supplying power to the main body of the walking aid device is more in line with the device's operating standards. It also reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery, thereby improving the safety of battery use and ultimately enhancing the safety of the walking aid device.

[0066] E5. In step E2 above, if the battery serial number is obtained and the battery is determined to be valid, then a second error message is sent.

[0067] If a communication timeout is detected, and the battery is deemed valid, a second error message is sent to alert the user.

[0068] After the second threshold time, cancel the error and reacquire the battery's power supply signal and serial number.

[0069] By canceling the error report after the second threshold time and re-acquiring the battery's power supply signal and serial number, the battery can promptly resume powering the main body of the walking aid device after communication is restored, thus improving the reliability of the walking aid device.

[0070] In some embodiments, the second threshold time can be 10 seconds, 15 seconds, or 20 seconds, etc.

[0071] Example 4 Figure 4 In the illustrated embodiment, a battery management device 10 for a walking aid includes a communication circuit 110 and a processor 120. It employs the battery management method for a walking aid described in one of the above embodiments. The communication circuit 110 is used to acquire the battery's serial number, which includes a first sub-serial number and a second sub-serial number. The processor 120 is connected to the communication circuit and is used to determine whether the first sub-serial number and the second sub-serial number are both compliant. If both are compliant, the battery is valid, allowing it to supply power to the main body of the walking aid. If the first sub-serial number and the second sub-serial number are not compliant simultaneously, the battery is allowed to supply power to the main body of the walking aid for a first threshold time period, or the battery is prohibited from supplying power to the main body of the walking aid. Other aspects are the same as in Embodiments 1, 2, and 3.

[0072] By allowing or prohibiting the battery from supplying power to the main body of the walking aid device within a first threshold time when the first and second sub-serial numbers are not simultaneously compliant, the battery supplying power to the main body of the walking aid device can be made more compliant with the operating standards of the walking aid device. This reduces the risk of malfunctions, sudden stops, or rapid accelerations caused by voltage or current mismatch or instability provided by the battery, thus improving the safety of battery use and consequently the safety of the walking aid device. Furthermore, because the output current of a compliant battery is more stable, the likelihood of the motor in the main body of the walking aid device generating additional heat due to current fluctuations is lower, which slows down the aging of the motor's insulation materials. The likelihood of damage to components in the controller of the main body of the walking aid device due to frequent voltage fluctuations is also lower. At the same time, the likelihood of the battery experiencing false charges or incomplete charging is also lower, reducing the possibility of limiting the driving range of the walking aid device.

[0073] Example 5 Figure 5 In the illustrated embodiment, a walking aid device battery storage device 20 includes a storage unit (i.e., a storage function unit typically found in storage devices). The storage unit stores program data 210, which can be executed by the walking aid device battery management device described in Embodiment 4 to implement the walking aid device battery management method described in any one of Embodiments 1 to 3. The storage device in this embodiment can be, but is not limited to, a USB flash drive, SD card, PD optical drive, portable hard drive, high-capacity floppy drive, flash memory, multimedia memory card, or server, etc. Other aspects are the same as in Embodiments 1, 2, 3, and 4.
