Description

[Technical Field]

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

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

[0003] Electronic products are constantly being updated with new functions, and their lifespans are getting shorter and shorter, eventually evolving into consumables. After using electronic products for a period of time, they usually malfunction. At this time, people often send the malfunctioning electronic products to electronics stores, which then send them to the original manufacturer on their behalf. Because the original manufacturer receives a large number of electronic products for repair, their staff need to spend time testing and repairing them, resulting in consumers having to wait a long time to receive their repaired electronic products.

[0004] Consumers and distributors typically lack the tools to determine the condition of batteries. When electronic products fail to power on or experience other malfunctions, consumers and distributors often assume the battery is faulty and send the battery or the product back to the manufacturer. However, sometimes it may simply be a protection function activation, not a battery failure. Once the protection function 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 and creates a negative user experience. [Summary of the Invention]

[0005] To address the shortcomings of existing technologies, the present 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 a battery pack. The battery information control module is configured to display the battery status information received through the management information transmission module on the battery information network platform. When the battery information control module is connected to a user device through the management information transmission module, the battery information control module provides an internal connection between the battery information network platform and the user device through the management information transmission module.

[0011] Please refer to Figures 1 and 2, wherein Figure 1 is a block diagram of the battery state management device of the first embodiment of the present invention, and Figure 2 is a flowchart of the steps of the battery state management method of the first embodiment of the present invention.

[0012] 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 as a battery pack in this document, but in practice it can be replaced with a battery.

[0013] As shown in Figure 1, 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 may be a processor, a cloud server, or other hardware device.

[0014] As shown in FIG1, the battery state management device 100 of the present invention is suitable for executing steps S11 to S15 of the battery state management method of the present invention as shown in FIG2.

[0015] 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.

[0016] The battery information management module 120 wirelessly connects (or in practice, wiredly connects) to the battery pack 200 via the management information transmission module 110 to receive battery status information from the battery pack 200 (as shown in step S11 of Figure 2). The management information transmission module 110 described herein can be a wireless transmission element, such as a wireless router or other hardware device, employing WIFI, Bluetooth, or other wireless transmission technologies.

[0017] 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.

[0018] The battery information management module 120 transmits the received battery status information of the battery pack 200 to the battery information network platform 130 in real time, so as to display the battery status information on the web page of the battery information network platform 130 (as shown in step S12 of Figure 2).

[0019] Since the health status of the battery pack 200 changes with the length of time it is used, the management information transmission module 110 can continuously or repeatedly receive battery status information from the battery pack 200, and transmit the 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 time points / different usage durations, or it can only display the last updated battery status information.

[0020] 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 wired) to the battery status management device 100 of the present invention (as shown in step S13 of FIG2).

[0021] When the user device 300 connects to the battery information control module 120 through the management information transmission module 110 of the battery status management device 100 of the present invention (as shown in step S13 of FIG2), the battery information control module 120 of the battery status management device 100 of the present invention can provide an internal link of the battery information network platform 130, a URL of an internal webpage, or other related link information to the user device 300 through the management information transmission module 110 (as shown in step S14 of FIG2).

[0022] In detail, when a consumer wants to obtain battery status information of battery pack 200, the consumer can enter the wireless connection range of the battery status management device 100 of the present invention through service personnel such as store staff or preliminary assessment personnel holding user terminal device 300 (and after successfully authenticating their identity by entering or selecting account and password on user terminal device 300 and through management information transmission module 110), user terminal device 300 can obtain an internal link, an internal webpage URL or other related link information of battery information network platform 130 provided by battery information control module 120 through management information transmission module 110 and use the obtained link information to open and enter battery information network platform 130 on user terminal device 300 (on a browser).

[0023] When the user device 300 successfully connects wirelessly to or connects to the battery status management device 100 of the present invention, it means 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 (as shown in step S15 of Figure 2), and grants the user device 300 permission to open, view (set and modify) the battery status information of the battery pack 200 displayed on the battery information network platform 130.

[0024] 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.

[0025] In other words, the battery status management device 100 of the present invention can provide consumers with the option to go to the nearest store or other service institution when the battery pack 200 they are using malfunctions. At the service institution, 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 of the present invention to transmit the battery status information of the battery pack 200 to the battery status management device 100 of the present invention, which then displays it on the battery information network platform 130. Next, the service personnel use the user device 300 to wirelessly (or practically wired) connect to the battery status management device 100 of the present invention to view the battery status information of the battery pack 200 displayed on the battery information network platform 130, thereby determining whether the battery pack 200 they are using 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.

[0026] Please refer to Figures 3 and 4, wherein Figure 3 is a block diagram of the battery state management device of the second embodiment of the present invention, and Figure 4 is a flowchart of the steps of the battery state management method of the second embodiment of the present invention.

[0027] As shown in FIG3, 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.

[0028] The battery state management device 100 of the present invention is applicable to, or in practice further includes, a battery pack 200. As shown in FIG3, the battery pack 200 includes battery cells 210, a battery state detection unit 220, a battery management unit 230, and a battery state transmission unit 240, wherein the battery cell 210 may include multiple batteries BT. In practice, the number of batteries BT included in the battery cell 210 can be adjusted according to actual needs. If necessary, the battery pack 200 may further include a charging switch CT, a discharging switch DT, a sensing resistor R, or any combination thereof.

[0029] The battery status detection unit 220 is a sensor or other integrated circuit with sensing 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.

[0030] The battery pack 200 shown in FIG3 is suitable for performing steps S21 to S24 of the battery state management method of the present invention shown in FIG4.

[0031] 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.

[0032] The first terminal of the discharge switch DT of the battery pack 200 is connected to the positive terminal P1 of the 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 the 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 terminals of the batteries BT that preceded them.

[0033] Within the battery pack 200, the battery state detection unit 220 can be connected to the positive or negative terminal of any one or more of the multiple batteries BT to detect the current, voltage, or both of the battery cell 210, and output battery detection data (as shown in step S21 of Figure 4). The battery state detection unit 220 can also be connected to the first terminal, the second terminal, or both of the sensing resistor R. The first terminal of the sensing resistor R is further connected to the negative terminal of the last battery BT in the multiple battery pack 200, and the second terminal of the sensing 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 sensing resistor R. Then, the battery management unit 230 can use the current of the sensing resistor R as the current of the battery cell 210, or calculate the current of the sensing resistor R based on the voltage and resistance value of the sensing resistor R as the current of the battery cell 210, and output battery detection data based on the current, voltage, or both of the battery cell 210 (as shown in step S21 of Figure 4).

[0034] Within the battery pack 200, the battery status detection unit 220 determines the status of the battery pack 200 based on the battery detection data received from the battery status detection unit 220, such as determining whether the battery pack 200 is a defective product (as shown in step S22 of Figure 4), or determining whether it is a good product, so as to generate battery status information.

[0035] For example, when the battery status detection unit 220 determines that the voltage of the battery cell 210 contained in the battery detection data received from the battery status detection unit 220 after being charged for a preset charging time is lower than a voltage threshold value, the battery status detection unit 220 determines that the battery pack 200 is defective.

[0036] Conversely, when the battery status detection unit 220 determines that the voltage of the battery cell 210 contained in the battery detection data received from the battery status detection unit 220 after being charged for a preset charging time is not lower than a voltage threshold value, the battery status detection unit 220 determines that the battery pack 200 is a good product.

[0037] Further, when the battery management unit 230 determines that the battery pack 200 is a good product / 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 (as shown in step S23 of Figure 4). Conversely, when the battery management unit 230 determines that the battery pack 200 is a defective product / not a good product based on the battery detection data, the battery management unit 230 outputs battery status information containing a defective product information code (as shown in step S24 of Figure 4).

[0038] 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 modifies the good product information code to form a defective product information code and outputs battery status information containing the defective product information code.

[0039] The battery status transmission unit 240 of the battery status management device 100 of the present invention can be wirelessly connected (or wired in practice) to the battery status transmission unit 240 of the battery pack 200 to receive battery status information of the battery pack 200 from the battery status transmission unit 240 (as shown in step S11 of FIG2).

[0040] Please refer to Figure 5, which is a schematic diagram of 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.

[0041] The battery state management device and method of the present invention, such as the battery state management device of the present invention in FIG3 and the battery state management method of the present invention in FIG4, are applicable to the usage scenarios of the battery pack 200 and the user terminal device 300 shown in FIG5.

[0042] 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 a good product information to the battery management unit 230 of battery pack 200 for storage. Afterwards, battery supplier H1 ships battery pack 200 containing the good product information code / valid code representing a good product information.

[0043] Electronic product manufacturer H2 will purchase battery packs 200 from battery supplier H1 or other sources and install them into electronic products such as, but not limited to, notebook computers 2000 as shown in Figure 5, and ship them to electronics retail store H3.

[0044] A consumer purchases a notebook computer 2000 equipped with a battery pack 200 from an electronics retailer H3. When the consumer uses the notebook computer 2000, the battery pack 200 or other electronic components inside the notebook computer 2000 may be damaged or malfunction due to various reasons such as the consumer's usage habits and the length of time. Therefore, the battery status detection unit 220 inside the battery pack 200 of the notebook computer 2000 continuously detects the battery detection 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 detection data.

[0045] When a laptop 2000 malfunctions and becomes unusable, previously neither the consumer nor the service personnel at the electronics retailer H3 knew whether the problem was caused by a damaged battery pack 200 installed in the laptop 2000. Therefore, the electronics retailer H3 would send the battery pack 200 of the electronic product (such as a laptop 2000 or a mobile phone) to the battery supplier H1 and the electronic product 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 the present 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.

[0046] When the battery pack 200 is a good product, the code displayed by the battery information control module 120 on the battery information network platform 130 remains the same as the good product message code / valid code representing a good product. Conversely, when the battery pack 200 becomes a defective product, the code displayed by the battery information control module 120 on the battery information network platform is updated to the same as the defective product message code / invalid code representing a defective product.

[0047] When a consumer experiences a malfunction in an electronic product, such as a laptop computer 2000, equipped with a battery pack 200, 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, wiredly connect) the battery pack 200 to obtain the battery pack 200's code and display it on the battery information network platform 130.

[0048] Next, the service personnel of the electrical appliance store H3 operate the terminal device 300 to wirelessly (or in practice, wired) connect to the battery status management device 100 of the present invention provided by the electrical appliance store H3 in order to view the current code of the battery pack 200 displayed on the battery information network platform 130.

[0049] 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 store 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 store 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 store 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 that the battery supplier H1 receives for repair, thus effectively reducing the workload of the service personnel of the battery supplier H1 in the work of receiving and repairing.

[0050] Please refer to Figure 6, which 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.

[0051] 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.

[0052] For example, the service personnel of the battery supplier H1 can operate the terminal device 300 to fill in / modify one or more preset valid codes / preset good codes that represent that the battery pack 200 is a good product as displayed on the battery information network platform 130, such as, but not limited to, the multiple preset valid codes shown in FIG6, such as, but not limited to, “0x0018H”, “0x0010H”, “0x0008H”.

[0053] As shown in Figure 6, when the service personnel of the electrical appliance store H3 view / read the current code "0x0010H" of the battery pack 200 displayed on the battery information network platform 130, and it is the same as at least one of the multiple preset valid codes "0x0010H", they can know that the battery pack 200 purchased by the consumer (and used by the consumer) is currently a good product.

[0054] Please refer to Figure 7, which 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.

[0055] Compared to the fourth embodiment in Figure 6, which sets three preset valid codes / preset good codes “0x0018H”, “0x0010H”, and “0x0008H” to represent that the battery pack 200 is a good product and displays them on the battery information network platform 130, as shown in Figure 7, in the fifth embodiment, only two preset valid codes “0x0010H” and “0x0008H” are set to represent that the battery pack 200 is a good product.

[0056] Therefore, when the service personnel of the electrical appliance store H3 view / read the current code of the battery pack 200 displayed on the battery information network platform 130, such as "0x0018H", as shown in Figure 7, which is different from each of the multiple preset valid codes / preset good codes "0x0010H" and "0x0008H", they can know that the battery pack 200 purchased by the consumer (and used by the consumer) is currently a defective product.

[0057] Please refer to Figure 8, which is a schematic diagram of a preset good product message code representing a good product set on the battery information network platform included in the battery status management device of the sixth embodiment of the present invention.

[0058] To set or modify the default valid code displayed on a homepage / battery information webpage of the battery information network platform 130 as shown in Figures 6 and 7, you can click or otherwise trigger a setting page switching key BU1 displayed on a homepage / battery information webpage to switch the homepage / battery information webpage displayed on the battery information network platform 130 to a setting page as shown in Figure 8 or 9.

[0059] Service personnel of battery supplier H1 can operate the user terminal device 300 to fill in 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 fill in or modify one or more preset valid codes in a valid code setting block BK2, such as but not limited to "0018" as shown in FIG8. After modification, a save key BU3 displayed on the setting page is triggered to trigger the battery information network platform 130 to save and display the updated preset valid codes on a homepage / battery information webpage. Then, service personnel of battery supplier H1 can operate the user terminal device 300 to select or otherwise trigger a homepage switch key / battery information webpage switch key BU2 to switch the setting page displayed on the battery information network platform 130 to a homepage / battery information webpage.

[0060] Please refer to Figure 9, which is a schematic diagram of the battery information network platform included in the battery status management device of the seventh embodiment of the present invention setting multiple preset good product message codes representing good products.

[0061] Unlike Figure 8, which only sets a single preset valid code / preset good product message code "0018", Figure 9 shows multiple preset valid codes / preset good product message codes "0008", "0010", and "0018". In practice, users with different information modification permissions can set different numbers and values ​​of preset valid codes according to different actual needs and usage habits.

[0062] 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 instantly acquire battery status information 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 terminal device to the battery status management device, the device receives relevant information such as internal connections to the battery information network platform. This allows the user to access the battery information network platform on their terminal device and view battery-related status information to confirm whether the battery is damaged.
