Description

Electronic equipment and battery warning method

technical field

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

Background technique

Lithium-ion batteries have the characteristics of high voltage, high energy, high power and long service life, and have been widely used in consumer electronics, electric vehicles and other fields.

A commonly used lithium-ion battery is a graphite anode lithium-ion battery. Although the graphite anode lithium ion battery has the advantages of low price and low lithium intercalation potential, with the continuous increase of functions such as smart terminals and electric vehicles in recent years, the use intensity and requirements of the battery have gradually increased. It is increasingly difficult to meet the power consumption requirements of electronic devices.

Silicon material can form a multi-phase alloy (LixSi) with lithium, the theoretical specific capacity at room temperature is about 3600mAh/g, and the lithium intercalation voltage is about 0.4V, which is much higher than that of graphite anode lithium-ion batteries. The anode specific capacity of the traditional graphite anode lithium-ion battery is about 372mAh/g, and the lithium insertion voltage is about 0.05V. Therefore, silicon anode lithium-ion battery is a very potential research direction to improve the energy density of lithium-ion battery.

After a lithium-ion battery undergoes multiple charge-discharge cycles, the overall thickness of the battery will increase to varying degrees. One of the reasons for this is that the structure of the material expands after the continuous insertion of lithium ions. It has been reported in the literature that the volume of graphite negative electrodes expands by dozens of times after fully intercalated lithium ions, while the expansion of silicon-based negative electrodes can be as high as hundreds of times. Therefore, during the use of the battery, especially the use of the silicon anode lithium ion battery, the expansion of the battery should be the object of monitoring to avoid 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 form the prior art that is already known to a person of ordinary skill in the art.

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 in order to give a thorough understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be employed. In other instances, well-known structures, methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

Furthermore, in the description of the present disclosure, "plurality" means at least two, such as two, three, etc., unless expressly and specifically defined otherwise.

The electronic device 10 as shown in FIG. 1 may be, for example, a terminal or a communication terminal, including but not limited to being configured to be connected via a wired line, such as via a public switched telephone network (PSTN), digital subscriber digital subscriber line (DSL), digital cable, direct cable connection, and/or another data connection/network and/or via, for example, for cellular networks, wireless local area networks (WLAN), such as handheld digital video Digital video broadcasting handheld (DVB-H) network digital television network, satellite network, AM-FM (amplitude modulation-frequency modulation, AM-FM) broadcast transmitter, and/or wireless interface of another communication terminal to receive/transmit communications Signal device. A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", a "wireless terminal" and/or a "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal communication system (PCS) terminals that may combine cellular radio telephones with data processing, facsimile, and data communication capabilities; may include radio telephones, pagers, Internet/ Personal Digital Assistant (PDA) with intranet access, web browser, memo pad, calendar, and/or global positioning system (GPS) receiver; and conventional laptop and/or palmtop A receiver or other electronic device including a radiotelephone transceiver. In addition, the terminal may also include, but is not limited to, e-book readers, smart wearable devices, mobile power supplies (such as power banks, travel chargers), electronic cigarettes, wireless mice, wireless keyboards, wireless earphones, Bluetooth speakers, etc. Rechargeable electronic devices. In addition, the electronic device 10 may also be an electric vehicle using a lithium-ion battery as an energy source.

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

The detection module 12 is used to detect the volume change of the battery 11 .

The detection module 12 may, for example, perform detection when the battery 11 is being charged, such as periodically, or when the battery 11 starts to be charged and/or when the battery 11 is fully charged. In addition, the detection module 12 can also detect when the battery 11 is not charged, such as periodic detection, and the period can be set to be longer, such as one week or even one month. The present disclosure is not limited thereto.

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

The control module 13 can be implemented by, for example, an independent micro control unit (Micro Control Unit, MCU), or can also be implemented by an application processor (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 less than the second threshold When the battery 11 is larger than or equal to the second threshold, the battery 11 is controlled to stop supplying power to the electronic device 10 and/or the battery is controlled 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 close the power supply channel of the battery 11 to the electronic device 10 , and/or the control module 13 controls the charging of the battery 11 by controlling the closing of the charging channel to the battery 11 .

The above-mentioned first threshold value and second threshold value can be determined based on the negative electrode material of the battery 11 , for example. For example, the expansion rate of graphite anode lithium-ion batteries and silicon anode lithium-ion batteries with a silicon content of less than 10% needs to be controlled below 8%, while the expansion rate of silicon anode lithium-ion batteries with a silicon content of 20% needs to be controlled. below 10%. Therefore, taking the graphite negative electrode lithium ion as an example, the first threshold can be set to the first data corresponding to the expansion rate of 8% according to the volume change data, and the second threshold can be set to the first data corresponding to the expansion rate of 15% according to the volume change data. Two data. It should be noted that, in practical applications, the settings of the first threshold and the second threshold may be determined according to actual requirements, and the present disclosure is not limited thereto.

In some embodiments, the first-level battery warning information can be used to prompt the user that the battery has aged and the battery status has begun to decline; the second-level battery warning information can be used to prompt the user to replace the battery 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 . For example, the thickness sensor may include a plurality of them. FIG. 2A and FIG. 2B are schematic diagrams showing the setting positions of the thickness sensor according to an exemplary embodiment, respectively. As shown in FIG. 2A , the thickness sensor may, for example, be arranged on the upper and lower sides of the battery 11 (as shown by the arrows in the figure), or may be arranged around the battery 11 as shown in FIG. 2B (as shown by the arrows in the figure) Show).

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

In some embodiments, the battery 11 may also be a battery pack used in an electric vehicle. FIG. 3 is a schematic diagram of a battery 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 11a. Wherein, each battery module 11a includes a plurality of battery cells 11b. In this case, the thickness sensors are respectively disposed on the upper and lower sides of each cell 11b, or are respectively disposed around each cell 11b. The thickness of the battery pack 11 is the accumulated value of the measured thickness of each cell.

For example, the thickness sensor can be a contact thickness sensor, such as an inductive displacement sensor, a capacitive displacement sensor, a potentiometer type displacement sensor, a Hall type displacement sensor, etc.; or, it can also be a non-contact thickness sensor, such as a laser thickness sensor , Eddy current thickness sensor, magnetic thickness sensor, capacitive thickness sensor, ultrasonic thickness sensor, nuclear radiation thickness sensor, X-ray thickness sensor, microwave thickness sensor, etc. The present disclosure is not limited thereto.

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

FIG. 4A is a schematic diagram of a tension sensor according to an exemplary embodiment. FIG. 4B is a schematic diagram of a thin-film-covered cell according to an exemplary embodiment.

As shown in FIGS. 4A and 4B , the tension sensor 12B is provided outside the film F, and detects the volume change data of the battery 11 by detecting the tension of the elastic film F covering the outer surface of the battery 11 . When the thickness of the battery 11 is increased, the film F is stretched accordingly, and then its tension is increased. The micro tension sensor 12B measures the tension of the film F, the tension change corresponding to the volume change of the battery 11 . The above-mentioned 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 tension sensors 12B, respectively covering the outer surface of each module 11a to measure the volume change data of each module 11a. It should be noted that this situation usually needs to be carried out in a closed space, otherwise the measured tension data may be inaccurate. Therefore, it is necessary to maintain good sealing properties 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 each battery module 11a.

In addition, the detection module 12 may also include a thickness sensor and a tension sensor, respectively, for measuring the thickness of the battery 11 and the tension of the film wrapped on the outer surface of the battery 11 . When making battery warning judgment, for example, two measured values can be converted into data with unified meaning (such as the volume of battery 11 ), and the final data value can be obtained according to the two data values (for example, a weighted average method is used), and then The threshold value is judged according to the final data value. Alternatively, it is also possible to independently perform the threshold value judgment on the two measurement values separately, and correspondingly different threshold values need to be set.
