Description

Technical Field

[0001] This invention relates to batteries, and more particularly to a battery state management device and method. Background Technology

[0002] Electronic products are now widely used in people's lives and have become an indispensable part of modern life. Many people purchase mobile phones, laptops, and other electronic products from electronics retailers. These electronic products, including laptops, are usually equipped with batteries to power other circuit components inside the electronic devices.

[0003] Electronic products are constantly being updated with new features, and their lifespans are getting shorter and shorter, eventually evolving into consumables. After using electronic products for a period of time, they often malfunction. At this point, people typically take the faulty electronic product to an electronics store, which then sends it to the original manufacturer. Because the original manufacturer receives a massive number of electronic products for repair, their staff needs time to test and repair them, resulting in consumers having to wait a considerable amount of time to receive their repaired electronic products.

[0004] Consumers and retailers typically lack the tools to determine battery quality. When electronic products fail to power on or experience other malfunctions, consumers and retailers often assume the battery is faulty and send the battery or the product back to the manufacturer. However, sometimes it might simply be a protection mechanism activating, not a battery failure. Once the protection mechanism is removed, the battery will function normally. Frequently sending perfectly good batteries back to the manufacturer for testing and damage assessment not only wastes time and money but also unnecessarily increases the workload of the manufacturer's staff, leading to a negative customer experience. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a battery status management device, comprising a battery information network platform, a management information transmission module, and a battery information control module. The management information transmission module is configured to receive battery status information from the battery pack. The battery information control module is configured to display the battery status information received via the management information transmission module on the battery information network platform. When the battery information control module connects to a user device via the management information transmission module, the battery information control module provides an internal link between the battery information network platform and the user device through the management information transmission module.

The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention. In addition, the term "or" as used herein may, depending on the actual situation, include any or more combinations of the associated listed items.

[0020] Please see Figure 1 and Figure 2 ,in Figure 1 This is a block diagram of a battery state management device according to a first embodiment of the present invention. Figure 2 This is a flowchart of the battery state management method according to the first embodiment of the present invention.

[0021] The battery status management device 100 of the present invention is suitable for managing information of a battery pack 200 (or, in practice, a single battery pack) and providing it to the user device 300 for viewing. For ease of explanation, it is described herein as a battery pack, but in practice it can be replaced with a battery.

[0022] like Figure 1 As shown, the battery status management device 100 of the present invention includes a management information transmission module 110, a battery information control module 120, and a battery information network platform 130. The battery information control module 120 described herein can be a processor, a cloud server, or other hardware device.

[0023] like Figure 1 The battery state management device 100 of the present invention shown is suitable for performing, for example... Figure 2 The battery state management method of the present invention shown includes steps S11 to S15.

[0024] The battery state management device 100 and battery state management method of the present invention are applicable to or further include a battery pack 200.

[0025] The battery information management module 120 wirelessly connects to the battery pack 200 via the management information transmission module 110 (or, in practice, via a wired connection) to receive battery status information (such as battery status data) from the battery pack 200 through the management information transmission module 110. Figure 2 (Step S11). The management information transmission module 110 described herein may be a wireless transmission component, such as a wireless router or other hardware device, employing WIFI, Bluetooth, or other wireless transmission technologies.

[0026] The battery status information of the battery pack 200 described herein may include relevant information indicating whether the battery pack 200 is a good or defective product, the voltage of the battery pack 200, the current of the battery pack 200, the power consumption of the battery pack 200, the usage time of the battery pack 200, the model of the battery pack 200, the type of the battery pack 200, the manufacturing date of the battery pack 200, the expiration date of the battery pack 200, or any combination thereof.

[0027] The battery information management module 120 transmits the received battery status information from the battery pack 200 to the battery information network platform 130 in real time, so that the battery status information (e.g., battery status information) can be displayed on the webpage of the battery information network platform 130. Figure 2 Step S12).

[0028] Since the health status of the battery pack 200 changes with the duration of its use, the management information transmission module 110 can continuously or repeatedly receive battery status information from the battery pack 200 and transmit subsequently received battery status information to the battery information network platform 130 for display, thereby updating the battery status information on the battery information network platform 130. The battery information network platform 130 can display the battery status information of the battery pack 200 at different times / different usage durations, or it can only display the last updated battery status information.

[0029] When the user device 300 wants to obtain the battery status information of the battery pack 200, the user device 300 wirelessly connects (or in practice, wiredly connects) to the battery status management device 100 of the present invention (e.g., Figure 2 Step S13).

[0030] When the user device 300 connects to the battery information control module 120 (e.g., the battery status management device 100 of the present invention) through the management information transmission module 110, the battery information control module 120 is connected to the battery information control module 120. Figure 2 In step S13), the battery information control module 120 of the battery state management device 100 of the present invention can provide an internal link, an internal webpage URL, or other relevant link information of the battery information network platform 130 to the user device 300 through the management information transmission module 110. Figure 2 Step S14).

[0031] In detail, when a consumer wants to obtain the battery status information of the battery pack 200, the consumer can enter the wireless connection range of the battery status management device 100 of the present invention through a service personnel such as store staff or preliminary assessment personnel holding a user terminal device 300 (and after successfully authenticating their identity by entering or selecting an account and password on the user terminal device 300 through the management information transmission module 110). The user terminal device 300 can obtain an internal link, an internal webpage URL, or other relevant link information of the battery information network platform 130 provided by the battery information control module 120 through the management information transmission module 110 and use the obtained link information to open and enter the battery information network platform 130 on the user terminal device 300 (on a browser).

[0032] When the user device 300 successfully connects wirelessly to or connects to the battery status management device 100 of the present invention, it indicates that the user device 300 has been authenticated by the battery status management device 100 of the present invention. At this time, the battery status management device 100 of the present invention grants the user device 300 permission to access the battery information network platform 130 (e.g., Figure 2 In step S15), the user device 300 is granted permission to open, view (set and modify) the battery status information of the battery pack 200 displayed on the battery information network platform 130.

[0033] When the user device 300 successfully connects wirelessly to or connects to the battery status management device 100 of the present invention, the user device 300 can immediately open and access the battery information network platform 130 to view the battery status information displayed on the battery information network platform 130 opened by the user device 300.

[0034] In other words, the battery status management device 100 of this invention enables consumers to go to the nearest store or other service center when their battery pack 200 malfunctions. At the service center, service personnel such as store staff or preliminary assessment personnel remove the battery pack 200 from the electronic product and then wirelessly (or practically wired) connect the battery pack 200 to the battery status management device 100 to transmit the battery status information of the battery pack 200 to the battery status management device 100, which then displays it on the battery information network platform 130. Next, the service personnel use a user device 300 to wirelessly (or practically wired) connect to the battery status management device 100 to view the battery status information of the battery pack 200 displayed on the battery information network platform 130, thereby determining whether their battery pack 200 is damaged. If a consumer learns from a service representative that only the battery pack 200 is damaged (and is beyond the warranty period), they can easily find a nearby store to buy a new battery for replacement. If it is still under warranty, the electronic product can be sent back to the manufacturer.

[0035] Please see Figure 3 and Figure 4 ,in Figure 3 This is a block diagram of a battery state management device according to a second embodiment of the present invention. Figure 4 This is a flowchart illustrating the steps of a battery state management method according to a second embodiment of the present invention.

[0036] like Figure 3 As shown, the battery status management device 100 of the present invention includes a management information transmission module 110, a battery information control module 120, and a battery information network platform 130.

[0037] The battery state management device 100 of the present invention is applicable to, or in practice also includes, a battery pack 200. For example... Figure 3 As shown, the battery pack 200 includes battery cells 210, a battery status detection unit 220, a battery management unit 230, and a battery status transmission unit 240. Battery cells 210 may contain multiple battery BTs. In practice, the number of battery BTs in a battery cell 210 can be adjusted according to actual needs. If necessary, the battery pack 200 may also include a charging switch CT, a discharging switch DT, a detection resistor R, or any combination thereof.

[0038] The battery status detection unit 220 is a sensor or other integrated circuit with detection functions. The battery status transmission unit 240 is a communication chip or other integrated circuit with connection functions. The battery management unit 230 is a processor or other integrated circuit with the same or similar functions.

[0039] like Figure 3 The battery pack 200 shown is suitable for performing, for example Figure 4 The battery state management method of the present invention shown is as follows: Figure 4 Steps S21 to S24 are shown.

[0040] Within the battery pack 200, the control terminals of the charging switch CT and the discharging switch DT are connected to the battery management unit 230. The battery management unit 230 controls the operation of both the charging switch CT and the discharging switch DT.

[0041] The first terminal of the discharge switch DT of battery pack 200 is connected to the positive terminal P1 of battery pack 200. The second terminal of the discharge switch DT is connected to the first terminal of the charging switch CT. Multiple batteries BT are arranged sequentially and connected in series. The second terminal of the charging switch CT is connected to the positive terminal of the first battery BT in battery cell 210. Among the multiple batteries BT, except for the first one, the positive terminals of the other batteries BT are connected to the negative terminal of the preceding battery BT.

[0042] Within the battery pack 200, the battery status detection unit 220 can be connected to any one or more of the positive or negative terminals of the multiple batteries BT to detect the current, voltage, or both of the battery cells 210, and output battery detection data (such as...). Figure 4 (Step S21). The battery state detection unit 220 can also be connected to the first terminal, the second terminal, or both terminals of the detection resistor R. The first terminal of the detection resistor R is further connected to the negative terminal of the last battery BT in the plurality of batteries, and the second terminal of the detection resistor R is connected to the negative terminal P2 of the battery pack 200. In this configuration, the battery state detection unit 220 can detect the voltage, current, or both of the detection resistor R. Then, the battery management unit 230 can use the current of the detection resistor R as the current of the battery cell 210, or calculate the current of the detection resistor R as the current of the battery cell 210 based on the voltage and resistance value of the detection resistor R, and output battery detection data (e.g., ...) based on the current, voltage, or both of the battery cell 210. Figure 4 Step S21).

[0043] Within the battery pack 200, the battery status detection unit 220 determines the status of the battery pack 200 based on battery detection data received from the battery status detection unit 220, for example, determining whether the battery pack 200 is defective (e.g., ...). Figure 4 Step S22), or determine whether it is a good product, to generate battery status information.

[0044] For example, when the battery status detection unit 220 determines that the voltage of the battery cell 210 included in the battery detection data received from the battery status detection unit 220 after being charged for a default charging time is lower than a voltage threshold, the battery status detection unit 220 determines that the battery pack 200 is defective.

[0045] Conversely, when the battery status detection unit 220 determines that the voltage of the battery cell 210 included in the battery detection data received from the battery status detection unit 220 after being charged for a default charging time is not lower than a voltage threshold, the battery status detection unit 220 determines that the battery pack 200 is a good product.

[0046] Furthermore, when the battery management unit 230 determines that the battery pack 200 is a good product or not a defective product based on the battery detection data, the battery management unit 230 outputs battery status information containing a good product information code (e.g., ...). Figure 4 Step S23). Conversely, when the battery management unit 230 determines that the battery pack 200 is defective / not good based on the battery detection data, the battery management unit 230 outputs battery status information containing a defect information code (e.g., ...). Figure 4 Step S24).

[0047] For example, the battery management unit 230 of the battery pack 200 pre-stores a good product information code. When the battery management unit 230 determines that the battery pack 200 is defective based on the battery detection data, the battery management unit 230 modulates this good product information code to generate a defective product information code and outputs battery status information containing this defective product information code.

[0048] The battery status transmission unit 240 of the battery status management device 100 of the present invention can be wirelessly connected (or practically wired connected) to the battery status transmission unit 240 of the battery pack 200 to receive battery status information (such as battery status information of the battery pack 200) from the battery status transmission unit 240. Figure 2 Step S11).

[0049] Please see Figure 5 This is a schematic diagram illustrating the application of the battery state management device and method of the third embodiment of the present invention to an electronic product equipped with a battery.

[0050] The battery state management device and method of the present invention, for example Figure 3 The battery state management device of the present invention and Figure 4 The battery state management method of the present invention is applicable to, for example, Figure 5 The battery pack 200 and the user device 300 shown are used in the following scenarios.

[0051] During the production and inspection of battery pack 200, when battery supplier H1 detects that battery pack 200 is a good product, the user device 300 of battery supplier H1 transmits a good product information code / valid code representing good product information to the battery management unit 230 of battery pack 200 for storage. Afterwards, battery supplier H1 ships battery packs 200 containing the good product information code / valid code representing good product information.

[0052] Electronics manufacturer H2 will purchase battery packs 200 from battery supplier H1 or other sources and install them in electronic products, for example, but not limited to, Figure 5 The laptop computer shown was shipped to electronics store H3 within 2000 hours.

[0053] A consumer purchases a laptop computer 2000 equipped with a battery pack 200 from an electronics retailer, H3. When the consumer uses the laptop computer 2000, the battery pack 200 or other electronic components within the laptop computer 2000 may be damaged or malfunction due to various reasons such as the consumer's usage habits and the duration of use. Therefore, the battery status detection unit 220 within the battery pack 200 of the laptop computer 2000 continuously monitors the battery status data of the battery pack 200 as described above, and the battery management unit 230 determines whether the battery pack 200 has changed from a good product to a defective product based on the battery status data.

[0054] When a laptop computer 2000 malfunctions and becomes unusable, neither the consumer nor the service personnel at the electronics retailer H3 could determine whether the problem was caused by a damaged battery pack 200. Therefore, the electronics retailer H3 would send the battery pack 200 of the electronic product (such as a laptop computer 2000 or a mobile phone) to the battery supplier H1 and the electronics manufacturer H2 for repair, which was time-consuming, increased manpower, and transportation costs. Therefore, the battery information control module 120 of the battery status management device of this invention obtains the code of the battery pack 200 (included in the aforementioned battery status information) through the management information transmission module 110, and updates and displays the code of the battery pack 200 on the battery information network platform 130 in real time.

[0055] When battery pack 200 is a good product, the code displayed by battery information control module 120 on battery information network platform 130 remains the same as the good product information code / valid code representing a good product. Conversely, when battery pack 200 becomes a defective product, the code displayed by battery information control module 120 on battery information network platform is updated to the same as the defective product information code / invalid code representing a defective product.

[0056] When a consumer experiences a malfunction in an electronic product equipped with battery pack 200, such as a laptop computer 2000, the laptop computer 2000 can be returned to the electronics retailer H3. The service personnel at the electronics retailer H3 can first remove the battery pack 200 from the laptop computer 2000, and then use the battery status management device 100 of this invention to wirelessly connect (or in practice, wired connect) the battery pack 200 to obtain its code and display it on the battery information network platform 130.

[0057] Next, the service personnel of the electronics retail store H3 operate the terminal device 300 to wirelessly (or in practice, via wired connection) connect to the battery status management device 100 of the present invention provided by the electronics retail store H3 in order to view the current code of the battery pack 200 displayed on the battery information network platform 130.

[0058] When the code of the current battery pack 200 displayed on the battery information network platform 130 is the same as a good product information code representing a good product, the service personnel of the electronics retailer H3 determine that the malfunction of the laptop computer 2000 is not caused by damage to its built-in battery pack 200, and notify the consumer that there is no need to send the battery pack 200 to the battery supplier H1 through the electronics retailer H3. In other words, using the battery status management device and method of the present invention, the battery supplier H1 will only receive battery packs 200 that have been initially identified as defective by the electronics retailer H3, and will not receive a large number of battery packs 200 that are still good products. Therefore, the battery status management device and method of the present invention can effectively reduce the number of battery packs 200 or electronic products containing battery packs 200 received by the battery supplier H1 for repair, thus effectively reducing the workload of the battery supplier H1's service personnel in receiving and repairing these products.

[0059] Please see Figure 6 This is a schematic diagram showing that the battery pack is in good condition on the battery information network platform included in the battery status management device of the fourth embodiment of the present invention.

[0060] Battery supplier H1 can operate the user terminal device 300 to wirelessly connect to the management information transmission module of the battery status management device 100 of the present invention, and operate the user terminal device 300 to input or select an account and password. After successful authentication through the management information transmission module 110, it obtains the right to access the battery information network platform 130 and fill in / modify the battery status information and other information displayed on the battery information network platform 130.

[0061] For example, service personnel from battery supplier H1 can use the user-end device 300 to fill in / modify one or more default valid codes / default good codes displayed on the battery information network platform 130, representing that the battery pack 200 is a good product, such as, but not limited to, such as Figure 6The following are some of the default valid codes shown, such as, but not limited to, “0x0018H”, “0x0010H”, and “0x0008H”.

[0062] Service personnel at H3 electronics retail store, such as Figure 6 If the code "0x0010H" of the current battery pack 200 displayed on the battery information network platform 130 is the same as at least one of the multiple default valid codes "0x0010H", it can be known that the battery pack 200 purchased by the consumer (and used by the consumer) is currently a good product.

[0063] Please see Figure 7 This is a schematic diagram showing that the battery pack is defective on the battery information network platform included in the battery status management device of the fifth embodiment of the present invention.

[0064] compared to Figure 6 The fourth embodiment sets three default valid codes / default good codes "0x0018H", "0x0010H", and "0x0008H" to be displayed on the battery information network platform 130, representing that the battery pack 200 is a good product. Figure 7 As shown, in the fifth embodiment, the display is set to indicate that the battery pack 200 is a good product, and only two default valid codes "0x0010H" and "0x0008H" are displayed.

[0065] Therefore, the service personnel of the H3 electronics retail store, such as Figure 7 If the code of the current battery pack 200 displayed on the battery information network platform 130, such as "0x0018H", is different from each of the multiple default valid codes / default good codes "0x0010H" and "0x0008H", it can be known that the battery pack 200 purchased by the consumer (and used by the consumer) is currently a defective product.

[0066] Please see Figure 8 This is a schematic diagram of a default good product information code representing a good product being set on the battery information network platform included in the battery status management device of the sixth embodiment of the present invention.

[0067] To set or modify as follows Figure 6 and Figure 7 The default valid code displayed on the homepage / battery information webpage of the battery information network platform 130 can be clicked or otherwise activated by a setting page switching key BU1 displayed on the homepage / battery information webpage, so that the homepage / battery information webpage displayed on the battery information network platform 130 switches to, for example... Figure 8 or Figure 9 The settings page shown.

[0068] Battery supplier H1's service personnel can operate the user-end device 300 to enter or modify a network address in a network address setting block BK1 on a setting page of the battery information network platform 130, and / or enter or modify one or more default valid codes in a valid code setting block BK2, such as, but not limited to, Figure 8 The "0018" shown indicates that after modification, a storage key BU3 displayed on the settings page is activated to activate the battery information network platform 130 to store and display the updated default valid code on a homepage / battery information webpage. Next, the service personnel of battery supplier H1 can operate the user device 300 to select or otherwise activate a homepage switch key / battery information webpage switch key BU2, thereby switching the settings page displayed on the battery information network platform 130 to a homepage / battery information webpage.

[0069] Please see Figure 9 This is a schematic diagram showing how the battery information network platform included in the battery status management device of the seventh embodiment of the present invention sets multiple default good product information codes representing good products.

[0070] Unlike Figure 8 The example shown only sets a single default valid code / default good product information code "0018", such as... Figure 9 The diagram shows multiple default valid codes / default good product information codes "0008", "0010", and "0018". In practice, users with different information modification permissions can set different numbers and values ​​of default valid codes according to their actual needs and usage habits.

[0071] In summary, the present invention provides a battery status management device and method. The battery status management device and method of the present invention can acquire battery status information in real time and transmit it to a battery information network platform for display. Furthermore, when a user (e.g., a salesperson, a preliminary assessment personnel, or other service personnel) connects their device to the battery status management device, the device is provided with internal links to the battery information network platform and other relevant information, allowing the user to access the battery information network platform and view battery-related status information to confirm whether the battery is damaged.
