Description

Electronic equipment and battery early warning method

Technical Field

The disclosure relates to the technical field of charging, in particular to an electronic device and a battery early warning method.

Background

Lithium ion batteries have the characteristics of high voltage, high energy, high power, long service life and the like, and have been widely applied to the fields of consumer electronics, electric vehicles and the like.

A commonly used lithium ion battery is a graphite cathode lithium ion battery. Although the graphite cathode lithium ion battery has the advantages of low price, low lithium intercalation potential and the like, along with the continuous increase of functions of intelligent terminals, electric vehicles and the like in recent years, the use strength and the requirements of the battery are gradually improved, and the graphite cathode lithium ion battery is more and more difficult to meet the power consumption requirements of electronic equipment.

The silicon material and lithium can form a multi-phase alloy (LixSi), the theoretical specific capacity at room temperature is about 3600mAh/g, the lithium intercalation voltage is about 0.4V, and the theoretical specific capacity and the lithium intercalation voltage are far higher than those of a graphite cathode lithium ion battery. The specific capacity of the negative electrode of the traditional graphite negative electrode lithium ion battery is about 372mAh/g, and the lithium intercalation voltage is about 0.05V. Therefore, the silicon cathode lithium ion battery is a very potential research direction capable of improving the energy density of the lithium ion battery.

After the lithium ion battery is subjected to multiple charge-discharge cycles, the overall thickness of the battery is increased to different degrees. One reason for this is that the structure of the material expands after lithium ions are continuously inserted, and it is reported in literature that the volume expansion of a graphite negative electrode is tens of times after lithium ions are completely inserted, while the expansion of a silicon-based negative electrode is hundreds of times. Therefore, during the use of the battery, especially during the use of the silicon cathode lithium ion battery, the expansion of the battery should be taken as the object of monitoring to avoid the occurrence of danger.

The above information disclosed in this background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not constitute prior art that is already known to a person of ordinary skill in the art.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known structures, methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.

In the present disclosure, unless expressly stated or limited otherwise, the terms "connected" and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or as an integral part; can be a mechanical connection, can also be an electrical connection, or can also be a communication connection; they may be directly connected or indirectly connected through intervening media, or may be connected through one or more other elements or in an interactive relationship between two elements. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

Further, in the description of the present disclosure, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise. "and/or" describes the association relationship of the associated objects, and means that there may be three relationships, for example, a and/or B, and that there may be three cases of a alone, B alone, and a and B simultaneously.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, the thickness of a graphite negative electrode lithium ion battery generally increases by 5% to 10% after about 500 charge-discharge cycles, whereas the thickness of a silicon negative electrode lithium ion battery exceeds 15%.

In addition, during the use of the battery, the safety performance of the battery is poor, and thermal runaway is easy to occur. In the case of abuse such as overcharge, overdischarge, overvoltage, overcurrent and the like of the battery, internal decomposition including decomposition of the electrolyte, reaction of the electrode with the electrolyte and the like occurs, and gas is generated and released. These gases are first stored inside the battery after being released, increasing the pressure inside the battery and causing the volume of the cell to expand and deform slightly. Accumulated to a certain degree and can be emitted to the outside through the periphery. If the reaction is violent enough, the released gas will increase continuously, and after a certain degree, the danger of fire or even explosion will occur.

Therefore, it is necessary to provide a method for monitoring the battery usage status and determining whether to warn the battery according to the battery usage status.

The electronic device provided by the embodiments of the present disclosure is specifically described below.

The electronic device 10 as shown in fig. 1 may be, for example, a terminal or a communication terminal including, but not limited to, a device configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network and/or via, for example, a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a digital video broadcasting-handheld (DVB-H) network, a satellite network, an amplitude modulation-frequency modulation (AM-FM) broadcast transmitter, and/or a wireless interface of another communication terminal. Communication terminals arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", and/or "mobile terminals". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communication System (PCS) terminals that may combine a cellular radiotelephone with data processing, facsimile and data communication capabilities; personal Digital Assistants (PDAs) that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. In addition, the terminal may further include, but is not limited to, a rechargeable electronic device having a charging function, such as an electronic book reader, a smart wearable device, a mobile power source (e.g., a charger, a travel charger), an electronic cigarette, a wireless mouse, a wireless keyboard, a wireless headset, a bluetooth speaker, and the like. The electronic device 10 may be an electric vehicle using a lithium ion battery as an energy source.

Referring to fig. 1, an electronic device 10 includes: the device comprises a battery 11, a detection module 12, a control module 13 and an early warning module 14.

The detecting module 12 is used for detecting the volume change of the battery 11.

The detection module 12 may, for example, detect when the battery 11 is charging, such as periodically, or when the battery 11 begins to charge and/or the battery 11 is fully charged. Furthermore, the detection module 12 may also detect when the battery 11 is not charged, such as periodically detecting, and the period may be set to be longer, such as one week, even one month, etc. The present disclosure is not so limited.

The control module 13 is connected to the detection module 12 and the warning module 14, and configured to acquire volume change data of the battery 11 detected by the detection module 12, and send different levels of battery warning information to the warning module 14 according to the size of the volume change data.

The Control module 13 may be implemented, for example, by a separate Micro Control Unit (MCU), or may also be implemented by an Application Processor (AP) inside the electronic device 10.

In some embodiments, when the volume change data of the battery 11 is equal to the first threshold, the control module 13 sends first-level battery warning information to the warning module 14; when the volume change data of the battery 11 is greater than the first threshold and smaller than the second threshold, sending second-level battery warning information to the warning module 14; and when the volume change data of the battery 11 is greater than or equal to the second threshold, controlling the battery 11 to stop supplying power to the electronic device 10 and/or controlling the battery to be charged. For example, the control module 13 controls the battery 11 to stop supplying power to the electronic device 10 by controlling to turn off a power supply channel of the battery 11 to the electronic device 10, and/or the control module 13 controls to charge the battery 11 by controlling to turn off a charging channel of the battery 11.

The first threshold value and the second threshold value described above may be determined based on the negative electrode material of the battery 11, for example. For example, the expansion rate of a graphite negative electrode lithium ion battery and a silicon negative electrode lithium ion battery having a silicon content of 10% or less needs to be controlled to 8% or less, and the expansion rate of a silicon negative electrode lithium ion battery having a silicon content of 20% needs to be controlled to 10% or less. Therefore, taking the graphite negative electrode lithium ion as an example, the first threshold value may be set as the first data corresponding to the expansion rate of 8% according to the volume change data, and the second threshold value may be set as the second data corresponding to the expansion rate of 15% according to the volume change data. It should be noted that, in practical applications, the setting of the first threshold and the second threshold may be determined according to practical requirements, and the disclosure is not limited thereto.

In some embodiments, the first level battery warning information may be used to prompt the user that the battery has aged, that the battery status begins to drop, etc.; the second level battery warning information can be used for prompting a user to replace the battery so as to avoid danger.

The volume change data of the battery 11 detected by the detection module 12 may include, for example, thickness change data of the battery 11. The detection module 12 may include, for example, a thickness sensor for detecting the thickness of the battery 11. The thickness sensor may include a plurality of sensors. Fig. 2A and 2B are schematic views illustrating a thickness sensor arrangement position according to an exemplary embodiment, respectively. The thickness sensors may be disposed, for example, on both upper and lower sides of the battery 11 as shown in fig. 2A (as indicated by arrows in the figure), or may be disposed around the battery 11 as shown in fig. 2B (as indicated by arrows in the figure).

When the battery 11 includes a plurality of battery cells, the plurality of thickness sensors may be disposed on the upper and lower sides of each battery cell, or disposed around each battery cell. In this case, the thickness of the battery 11 is an accumulated value of the measured thickness of each cell.

In some embodiments, the battery 11 may also be a battery pack (pack) applied in an electric vehicle. Fig. 3 is a schematic diagram of a battery pack (pack) according to an exemplary embodiment. As shown in fig. 3, the battery pack 11 is a battery pack including a plurality of battery modules 11 a. Each battery module 11a includes a plurality of battery cells 11 b. In this case, the thickness sensors are disposed on the upper and lower sides of each of the battery cells 11b, respectively, or disposed around each of the battery cells, respectively. The thickness of the battery pack 11 is an accumulated value of the measured thickness of each cell.

The thickness sensor may be, for example, a contact-type thickness sensor, such as an inductive displacement sensor, a capacitive displacement sensor, a potentiometer-type displacement sensor, a hall-type displacement sensor, or the like; alternatively, a non-contact thickness sensor such as a laser thickness sensor, an eddy current thickness sensor, a magnetic thickness sensor, a capacitive thickness sensor, an ultrasonic thickness sensor, a nuclear radiation thickness sensor, an X-ray thickness sensor, a microwave thickness sensor, or the like may be used. The present disclosure is not so limited.

The detection module 12 may further include: and a tension sensor for detecting volume change data of the battery 11.

Fig. 4A is a schematic diagram of a tension sensor shown in accordance with an example embodiment. Fig. 4B is a schematic diagram illustrating a thin film covered battery according to an exemplary embodiment.

As shown in fig. 4A and 4B, the tension sensor 12B is provided outside the film F, and detects the tension of the elastic film F covering the outer surface of the battery 11, thereby detecting the volume change data of the battery 11. When the thickness of the battery 11 is increased, the film F is stretched accordingly, and then the tension thereof is increased. The micro tension sensor 12B measures the tension of the film F, which changes in tension correspond to the change in volume of the battery 11. And the volume change data can be determined according to the tension change data of the film.

When the battery 11 is the battery pack shown in fig. 3, the tension sensor 12B includes a plurality of sensors respectively covering the outer surface of each module 11a to measure the volume change data of each module 11 a. It should be noted that this is usually performed in a closed space, otherwise the measured tension data may be inaccurate. Therefore, it is necessary to maintain good sealability of the module or the battery pack. The volume change data of the battery pack shown in fig. 3 is the sum of the volume change data of the battery modules 11 a.

In addition, the detection module 12 may also include: and a thickness sensor and a tension sensor for measuring the thickness of the battery 11 and the tension of the film wrapped around the outer surface of the battery 11, respectively. When the battery warning judgment is performed, for example, the two measured values may be converted into data with a uniform meaning (for example, the volume of the battery 11), a final data value is obtained according to the two data values (for example, a weighted average method is adopted), and then the threshold judgment is performed according to the final data value. Alternatively, the threshold value determination may be performed separately for the two measurement values, and accordingly, it is necessary to set different threshold values for the two measurement values.

The warning module 14 is configured to prompt the user for the different levels of battery warning information.

In some embodiments, the early warning module 14 may, for example, comprise a multimedia component in the electronic device 10. The multimedia component includes a display module that provides an output interface between the electronic device 10 and the user. Different levels of battery warning information may be displayed to a user through the display module. The display module may include a Liquid Crystal Display (LCD) and a Touch Panel (TP). If the display module includes a touch panel, the display module may be implemented as a touch screen to receive an input signal from a user. The touch panel includes one or more touch sensors to sense touch, slide, and gestures on the touch panel. The touch sensor may not only sense the boundary of a touch or slide action, but also detect the duration and pressure associated with the touch or slide operation.

In some embodiments, the early warning module 14 may also include an audio module in the electronic device 10 configured to output and/or input audio signals. The battery early warning information of different levels can be prompted to the user by sending voice to the user through the audio module. For example, the audio module includes a speaker for outputting an audio signal. In addition, the audio module may also include a Microphone (MIC) configured to receive external audio signals when the electronic device 10 is in an operational mode, such as a call mode, a recording mode, and a voice recognition mode. The received audio signal may further be stored in a memory or transmitted via a communication component.

In addition, the prompt can be simultaneously provided for the user through the display module and the audio module.

The battery 11 in the electronic device 10 may be charged by a wired charging method or a wireless charging method, and the disclosure is not limited thereto.

It should be clearly understood that this disclosure describes how to make and use particular examples, but the principles of this disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.

For example, the volume change of the battery 11 may be detected by the detection module 12 in the electronic device 10.

As described above, the volume change data of the battery 11 detected by the detection module 12 may include, for example, the thickness of the battery 11. Alternatively, the volume change data of the battery 11 detected by the detection module 12 may also be determined according to the tension of the film wrapping the outer surface of the battery 11.

The arrangement of the detection module 12 in the battery 11 can be referred to the above device embodiments, and is not described herein.

The difference from the battery warning method shown in fig. 5 is that it further illustrates how to determine different levels of battery warning information according to the size of the volume change data of the battery, that is, fig. 6 further provides a specific embodiment of step S204.

As shown in fig. 6, step S204 may include:

in step S2042, when the volume change data is equal to the first threshold, it is determined that the battery warning information is first-level battery warning information.

The first-level battery warning information can be used for prompting the user that the battery is aged, the battery state begins to drop and the like.

In step S2044, when the volume change data is greater than the first threshold and smaller than the second threshold, it is determined that the battery warning information is the second-level battery warning information.

The second level battery warning information can be used for prompting a user to replace the battery so as to avoid danger.

In step S2046, when the volume change data is greater than or equal to the second threshold, the battery is controlled to stop supplying power to the electronic device and/or to charge the battery.
