Description

Technical Field

[0001] The present application belongs to the field of battery technology, and in particular relates to a battery type detection method, apparatus, terminal device, and computer program product. Background Art

[0002] In actual applications, rechargeable and non-rechargeable batteries are often mixed. Since rechargeable and non-rechargeable batteries of the same model (such as AA batteries and AAA batteries) are designed according to the same appearance standard, the external dimensions of rechargeable and non-rechargeable batteries are the same. Users need professional knowledge, time and patience to distinguish whether the two are rechargeable during use, which is difficult to do in daily use. The difficulty in distinguishing during discharge has little impact, but it has a greater hidden danger during charging. Charging non-rechargeable batteries may cause fires and explosions. Devices with built-in charging functions have a higher risk of mischarging due to the sealed battery. Due to the large number of battery types, there is currently no proper method to distinguish them. It mainly relies on manual identification, which is limited by the user's cognitive level. In particular, audio and video personnel are prone to errors when distinguishing between large numbers of batteries, resulting in incorrect matching of batteries and chargers, causing charging abnormalities and even explosions and fires.

[0047] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0048] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0049] The inventors of this application have noted that batteries distributed within certain voltage ranges include both non-rechargeable batteries. For example, batteries distributed within the 1V-2V voltage range include both non-rechargeable and rechargeable batteries. Non-rechargeable batteries primarily include dry-cell batteries with a nominal voltage of 1.5V, such as carbon batteries, alkaline batteries, lithium-iron batteries, and zinc-manganese batteries. Rechargeable batteries primarily include nickel-metal hydride and nickel-cadmium batteries with a nominal voltage of 1.2V, and nickel-zinc batteries with a nominal voltage of 1.6V.

[0050] Within the aforementioned voltage range, AA and AAA batteries are currently widely used. Whether rechargeable or non-rechargeable, these batteries, designed based on the AA or AAA battery appearance standards, have the same dimensions. Identifying whether a battery is rechargeable requires expertise, time, and patience, leading to a significant number of users being unable to distinguish between the two in daily use.

[0051] In order to solve the technical problem in the above-mentioned prior art that it is difficult for users to distinguish between rechargeable batteries and non-rechargeable batteries, the present application proposes a technical solution of a battery type detection method, device, terminal equipment and computer program product, which can automatically identify the battery type of the battery when the user cannot distinguish whether the battery type in a specific voltage range is a non-rechargeable battery type or a rechargeable battery type, while optimizing the user experience and ensuring the safety of battery charging.

[0052] In order to illustrate the technical solutions proposed in the embodiments of the present application, specific embodiments are provided below for illustration.

[0053] First, see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of a terminal device for detecting battery type provided by this application, such as Figure 1As shown, the terminal device of this embodiment includes: a processor 10, a memory 11, and a computer program 12 stored in the memory 11 and executable on the at least one processor 10. The terminal device of this embodiment also includes a charging unit 13 for charging the battery to be tested.

[0054] Figure 1 The terminal device shown may include, but is not limited to, a processor 10, a memory 11, and a charging unit 13. Those skilled in the art will understand that Figure 1 These are merely examples of terminal devices and do not constitute limitations on the terminal devices. The terminal devices may include more or fewer components than shown in the figure, or a combination of certain components, or different components. For example, the terminal devices may also include input and output devices, network access devices, etc. Figure 1 The terminal device shown may be a charging device dedicated to a certain type of battery.

[0055] In some embodiments, the memory 11 may be an internal storage unit of the terminal device, such as a hard disk or memory of the terminal device. In other embodiments, the memory 11 may also be an external storage device of the terminal device, such as a plug-in hard disk equipped on the terminal device, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), etc. Furthermore, the memory 11 may also include both an internal storage unit of the terminal device and an external storage device. The memory 11 is used to store an operating system, an application program, a boot loader (BootLoader), data, and other programs, such as the program code of the computer program. The memory 11 may also be used to temporarily store data that has been output or is to be output.

[0056] Specifically, refer to Figure 2 When the terminal device of the embodiment of the present application detects that a battery to be tested is connected, the processor 10 executes the computer program 12 to implement steps S10 to S30 of the embodiment of the battery type detection method of the present application:

[0057] Step S10: When the battery to be tested is connected to the terminal device, performing voltage detection on the battery to be tested to obtain a first current voltage of the battery to be tested, and comparing the first current voltage with a first preset voltage threshold;

[0058] It is understandable that the computer program 12 is triggered when the battery to be tested is inserted into or connected to the terminal device. In this embodiment, when the terminal device detects that a battery is connected, it immediately starts a voltage detection program to measure the first current voltage Va of the battery to be tested.

[0059] Step S20: When the first current voltage is greater than the first preset voltage threshold, determining that the type of the battery to be tested is a non-rechargeable battery;

[0060] Step S30: When the first current voltage is not greater than the first preset voltage threshold, charging the battery to be tested to continue detecting the type of the battery to be tested.

[0061] It should be noted that the battery to be tested in this embodiment is an AA battery or a AAA battery as an example, and the specific battery voltage range of the AA battery or the AAA battery is within 1V-2V.

[0062] If the first current voltage Va exceeds the first preset voltage threshold V1, it means that the voltage exceeds the upper limit of the critical region, and step S20 is executed to directly determine that the battery to be tested is a non-rechargeable battery. Otherwise, the process continues to run down to step S30, charging the battery to be tested to continue detecting the type of the battery to be tested.

[0063] The embodiment of the present application executes steps S10 to S30 to achieve blind identification of non-rechargeable batteries and rechargeable batteries in a specific battery voltage range of 1V-2V, especially being able to identify the type of non-rechargeable battery. When the type of non-rechargeable battery is identified, the terminal device sends a prompt message to remind the user, thereby avoiding the user's blind charging of the battery.

[0064] Further, refer to Figure 3 In some embodiments, step S30 further includes:

[0065] Step S31: When the first current voltage is not greater than the first preset voltage threshold, charging the battery to be tested to obtain a charging internal resistance of the battery to be tested;

[0066] In a specific implementation, a short charging operation can be applied to the battery under test to measure its charging internal resistance Rc. The specific acquisition method is as follows: (1) Applying charging current: In the battery identification process under test, when the voltage detection does not directly determine the battery type, the terminal device will apply a known charging current (usually a small current to avoid damaging the battery) to the battery under test; (2) Measuring voltage change: While applying the charging current, the terminal device will measure the voltage change at both ends of the battery under test. There is a direct relationship between this voltage change and the charging current and the battery internal resistance. (3) Calculating internal resistance: According to Ohm's law (V=IR), the terminal device can calculate the charging internal resistance Rc of the battery under test by measuring the voltage change and the known charging current.

[0067] Step S32: determining the type of the battery to be tested based on a comparison between the charging internal resistance and a preset internal resistance threshold;

[0068] Understandably, different types of batteries (e.g., rechargeable and non-rechargeable) within the same specific battery voltage range will exhibit different internal resistance characteristics during charging. These characteristics are determined by the chemical materials and structure within the battery.

[0069] In a specific implementation, the embodiments of the present application can determine the internal resistance range of rechargeable and non-rechargeable batteries during the charging process by testing and analyzing a large number of battery samples. Based on this data, a series of internal resistance thresholds (such as a first preset internal resistance threshold Rc1, a second preset internal resistance threshold Rc2, a third preset internal resistance threshold Rc3, etc.) can be preset to distinguish different types of batteries;

[0070] During the actual identification process, the battery's charging internal resistance is measured and compared with a preset internal resistance threshold. Based on this comparison, the battery's type can be determined. For example, if the charging internal resistance is greater than a preset threshold, the battery may be identified as non-rechargeable; otherwise, it may be identified as rechargeable.

[0071] Step S33: If the comparison relationship cannot determine the type of the battery to be tested, determine the type of the battery to be tested according to the current change rate of the battery to be tested during the charging process.

[0072] It is understandable that in some cases, relying solely on internal resistance comparison may not be able to completely accurately identify the battery type. The introduction of charging speed comparison can adapt to more complex battery usage scenarios. Different types of batteries exhibit different charging speed characteristics during the charging process. These characteristics can be used as a basis for distinguishing battery types. This embodiment can capture the characteristic differences between different batteries by measuring the current change rate (i.e., charging speed) during the charging process.

[0073] By performing charging tests on a large number of battery samples, the charging speed range of rechargeable batteries and non-rechargeable batteries during the charging process can be determined. In the actual identification process, the current charging speed of the battery to be tested is measured and compared with the preset charging speed. Based on the comparison result, the type of the battery to be tested can be determined. For example, if the charging speed is greater than a certain preset charging speed, it may be determined to be a certain type of battery; otherwise, it may be determined to be another type of battery (for step S33 of this embodiment, in some embodiments, the following can be performed to determine the type of battery to be tested). Figure 4 Steps S33a to S33f mentioned in the embodiment are used to further determine the battery type).

[0074] The beneficial effects of the embodiments of this application are as follows. By comparing the internal resistance and the rate of change of current during the charging process of the battery, the type of the battery can be further and more accurately identified, and more complex battery usage scenarios can be adapted.

[0075] Further, in some embodiments, there is another control method for the battery type detection method of the embodiments of this application. In this embodiment, the preset internal resistance threshold further includes a first preset internal resistance threshold Rc1, a second preset internal resistance threshold Rc2, and a third preset internal resistance threshold Rc3, where the first preset internal resistance threshold Rc1 is greater than the second preset internal resistance threshold Rc2, and the second preset internal resistance threshold Rc2 is greater than the third preset internal resistance threshold Rc3.

[0076] The specific process of the battery type detection method in this embodiment can refer to Figure 4 the flow schematic diagram shown below:

[0077] First, execute S10 to start the computer program to detect the first current voltage Va of the battery to be tested. If Va > V1, it means that the voltage Va exceeds the upper limit of the critical region, and step S20 can be executed to directly determine that the battery to be tested is a non-rechargeable battery; otherwise, the process continues to run downward to execute step S31 to obtain the charging internal resistance Rc of the battery to be tested by charging:

[0078] If the charging internal resistance Rc is greater than the first preset internal resistance threshold Rc1 (Rc > Rc1), then execute step S32a to determine that the type of the battery to be tested is a 1.5v constant voltage battery; otherwise, the process continues to run downward:

[0079] If the charging internal resistance Rc is greater than the second preset internal resistance threshold Rc2 (Rc > Rc2), then execute step S32b to determine that the type of the battery to be tested is a 1.5v non-rechargeable battery; otherwise, the process continues to run downward:

[0080] If the charging internal resistance is not greater than the third preset internal resistance threshold Rc3 (Rc < Rc3), then determine that the type of the battery to be tested is a rechargeable battery. Otherwise, enter the internal resistance critical region process and continue to run downward to execute:

[0081] Step S33a: Perform voltage detection on the battery to be tested to obtain the second current voltage Vb of the battery to be tested, and compare the second current voltage Vb with the second preset voltage threshold V2 (where the first preset voltage threshold V1 is greater than the second preset voltage threshold V2):

[0082] If the second current voltage Vb is greater than the second preset voltage threshold V2, then execute step S33b to determine that the type of the battery to be tested is a non-rechargeable battery; otherwise, the process continues to run downward:

[0083] Step S33c: collecting the current charging speed Ic_spd of the battery under test during the charging process; comparing the current charging speed Ic_spd with the second preset charging speed Ic_spd2:

[0084] If the current charging speed Ic_spd is greater than the second preset charging speed Ic_spd2 and greater than the first preset charging speed Ic_spd2, step S33d is executed to determine that the type of the battery to be tested is a non-rechargeable battery; otherwise, the process continues to run downward:

[0085] Step S33e: Determine the kth moment corresponding to executing step S33c, and count the charging time tc starting from the kth moment; compare the charging time tc with the preset charging duration tc1. If the charging time tc is greater than the preset charging duration tc1, execute step S33f to determine that the type of the battery to be tested is a rechargeable battery.

[0086] The beneficial effects of the embodiments of the present application are as follows: by incorporating two factors, namely the current change rate and charging duration of the battery under test during the charging process, the battery type of the battery under test can be further determined when the battery type cannot be determined solely by the battery voltage and internal resistance. This improves the accuracy and reliability of identification and helps protect the battery from damage. In addition, the battery type detection method of this embodiment automatically identifies the battery type, which can help users charge rechargeable batteries according to the identification results. This optimizes the user experience while ensuring battery charging safety, reduces the number of charging devices, and further saves users' selection time.

[0087] Furthermore, in one embodiment, the present invention also provides a battery type detection device, comprising:
