[0067] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0068] The following is a detailed description:

[0069] Figure 1 is a flow chart of a charging method of a terminal according to an exemplary embodiment. Figure 1 As shown, the method is applied to a non-magnetic charging terminal, including:

[0070] In step 101, it is detected that the terminal starts wireless charging, and the type of the wireless charging stand is determined;

[0071] In step 102, it is detected whether the terminal is equipped with a protective cover with an auxiliary magnetic suction function, wherein the protective cover includes a magnetic suction area covering the wireless charging area of ​​the terminal, and the magnetic suction area is used to assist the terminal in magnetic suction charging;

[0072] In step 103, when performing the wireless charging, corresponding charging compensation parameters are set according to the type of the wireless charging seat and whether the terminal is equipped with a protective cover; wherein the charging compensation parameters are used to adjust the sensitivity of foreign object detection during the charging process.

[0073] More and more electronic devices are beginning to support wireless charging functions, such as mobile phones, tablets, smart watches and other terminals, which can be charged by placing them on a wireless charging base. Common wireless charging bases include flat-placed ones, where the phone can be charged by placing it flat on the surface of the charging base; and inclined-placed ones, such as a charging base in the form of a mobile phone holder, where the phone is placed diagonally on it so that the charging coil on the back of the phone covers the charging area of ​​the charging base.

[0074] However, these charging bases need to be placed as close to the terminal as possible, and users need to pay attention to the placement. If the placement is not accurate, the charging effect will be affected. In addition, it is not convenient to move the terminal during charging, so it is difficult to charge on the go, which brings inconvenience to users.

[0075] Therefore, the magnetic charging base came into being. The magnetic charging base and the terminal with magnetic charging function can be fixed to each other through magnetism, so that they can be easily aligned with the charging area. Users can also easily move the terminal and the charging base during the charging process, and the two are not easy to separate, so as to maintain a better charging effect. Magnetic charging is also more suitable for terminals with smaller size that are more difficult to align with the charging area, such as smart watches, smart bracelets, etc. With the magnetic charging base, the two can be quickly adsorbed, which facilitates fast charging.

[0076] However, magnetic wireless charging requires the terminal to have a magnetic function, and a terminal without a magnetic function cannot experience the convenience and flexibility of magnetic wireless charging. In this regard, a protective cover with a magnetic function can be installed on the terminal, such as a magnetic mobile phone case, a watch case, etc.

[0077] Since metal foreign objects are easily attracted during magnetic wireless charging, which may cause interference, the terminal needs to have corresponding foreign object detection and protection functions during magnetic wireless charging. When interference from metal foreign objects is detected, charging needs to be stopped in time to prevent abnormalities caused by overheating.

[0078] For the above-mentioned non-magnetic charging terminal, if a protective cover with an auxiliary magnetic function is used, it is impossible to provide foreign object detection with appropriate sensitivity for magnetic charging, which may easily cause problems such as frequent charging interruptions or excessive charging temperature.

[0079] In the embodiments of the present disclosure, for a non-magnetic charging terminal, the type of the wireless charging stand can be detected during wireless charging, for example, whether it is a magnetic wireless charging stand. The terminal can establish a communication connection with the wireless charging stand during charging, and obtain relevant information about the wireless charging stand, including the type of the wireless charging stand, the charging power, etc.

[0080] In the disclosed embodiments, it is possible to detect whether the terminal is equipped with a protective cover with an auxiliary magnetic suction function. For example, the terminal can detect specific identification on the protective cover, such as an NFC identification, a sensing chip, etc., and can also directly detect the magnetic field generated by the magnetic suction area on the protective cover. Exemplarily, the protective cover here can be a mobile phone case, a tablet computer case, a laptop computer case, or a smart watch case, etc. Correspondingly, the terminal can be a mobile phone, tablet computer, laptop computer, or smart watch with a wireless charging function. The protective cover has a magnetic suction area. When the terminal is equipped with the protective cover, the magnetic suction area can cover the wireless charging area of ​​the terminal, thereby facilitating the auxiliary terminal to use a magnetic charging stand for magnetic suction charging.

[0081] It is understandable that even if the terminal is equipped with the above-mentioned protective cover, it can also be charged using a non-magnetic charging stand; conversely, if the terminal is not equipped with a protective cover, it can also be charged using a magnetic charging stand, but magnetic attraction cannot be achieved and manual alignment with the charging area is required. In other words, the possible situations include at least: using a magnetic charging stand with a protective cover, using a magnetic charging stand without a protective cover, using a non-magnetic charging stand with a protective cover, and using a non-magnetic charging stand without a protective cover.

[0082] The disclosed embodiment can determine which of the above situations actually occurs by detecting the type of charging stand and whether a protective cover is installed, thereby facilitating setting of corresponding charging compensation parameters.

[0083] The charging compensation parameter in the embodiment of the present disclosure can be used to adjust the sensitivity of the foreign object detection function during the charging process. The parameter can be an electrical parameter or a temperature parameter. Exemplarily, the external foreign object detection function (FOD) of wireless charging can determine whether there is a foreign object by detecting the surface temperature of the terminal. Therefore, the charging compensation parameter at this time can be used to compensate for the temperature threshold range for detecting foreign objects, so the charging compensation parameter is a temperature parameter; in addition, the received power can be detected to determine whether there is a foreign object. Therefore, the charging compensation parameter at this time can be a power parameter. In other words, the type and dimension of the above-mentioned charging compensation parameter can match the parameters corresponding to the detection method of the foreign object detection function of the terminal itself.

[0084] In this way, by detecting different charging conditions (charging stand type and whether a magnetic protective cover is worn), the terminal can set different charging compensation parameters to facilitate matching the charging characteristics in different situations and reduce frequent charging interruptions caused by excessively high foreign object detection sensitivity or severe heating caused by too low sensitivity.

[0085] In some embodiments, Figure 2 As shown, the method also includes:

[0086] In step 104, when performing the wireless charging, a corresponding charging mode is set according to the type of the wireless charging stand and whether the terminal is equipped with a protective cover.

[0087] For the above different situations, the terminal can adopt different charging modes for charging, that is, set different charging powers to improve safety performance while charging as quickly and stably as possible.

[0088] In some embodiments, the setting of the corresponding charging mode according to the type of the wireless charging stand and whether the terminal is equipped with a protective cover includes:

[0089] If the type of the wireless charging stand is a magnetic charging stand and the terminal is equipped with the protective cover, the magnetic fast charging mode is set;

[0090] If the type of the wireless charging stand is a non-magnetic charging stand and the terminal is equipped with the protective cover, the magnetic slow charging mode is set;

[0091] If the type of the wireless charging stand is a magnetic charging stand and the terminal is not equipped with the protective cover, the normal slow charging mode is set;

[0092] If the type of the wireless charging stand is a non-magnetic charging stand and the terminal is not equipped with the protective cover, it is set to the normal fast charging mode.

[0093] It can be understood that when using a magnetic charging stand and the terminal is equipped with a protective cover, since the contact between the terminal and the charging stand is closer, a higher charging transmission efficiency can be achieved, so a magnetic fast charging mode can be adopted, which can use high charging power to achieve fast charging.

[0094] When using a non-magnetic charging stand, magnetic charging is not actually possible. If the terminal is equipped with a protective cover, it is more likely to attract metal foreign objects and cause foreign object interference. Therefore, a low-power magnetic slow charging mode can be used to improve the stability of the charging process and reduce the problem of foreign object interference.

[0095] When using the magnetic charging stand but the terminal is not equipped with a protective cover, magnetic charging cannot actually be achieved. Similar to the second case, the charging stand is also prone to attracting metal foreign objects and causing foreign object interference. Therefore, a low-power mode can also be used, which is called the normal slow charging mode here, thereby improving the stability of charging and reducing the problem of foreign object interference.

[0096] When using a non-magnetic charging stand and the terminal is not equipped with a protective cover, that is, conventional wireless charging, since there is no magnetic attraction function, the possibility of attracting metal foreign objects is low, and the problem of foreign object interference is not likely to occur, so the normal fast charging mode can be used to achieve fast charging with high charging power.

[0097] In some embodiments, the sensitivity corresponding to the charging compensation parameter of the magnetic fast charging mode is lower than the sensitivity corresponding to the charging compensation parameter of the magnetic slow charging mode;

[0098] The sensitivity corresponding to the charging compensation parameter of the normal slow charging mode is higher than the sensitivity corresponding to the charging compensation parameter of the normal slow charging mode.

[0099] For the above-mentioned different charging modes, the above-mentioned charging compensation parameters may also be different. Considering that the magnetic suction function will increase the possibility of attracting metal foreign matter, therefore, when the charging seat has a magnetic suction charging seat and / or the terminal has a protective cover with an auxiliary magnetic suction function, the sensitivity corresponding to the charging compensation parameter can be greater than the sensitivity corresponding to the charging compensation parameter when the charging seat is not a magnetic suction charging seat and the terminal does not have a protective cover. That is, the sensitivity of the above-mentioned three modes, namely, the magnetic suction fast charging mode, the magnetic suction slow charging mode and the ordinary slow charging mode, is greater than the sensitivity of the ordinary fast charging mode.

[0100] In addition, since the above-mentioned magnetic fast charging mode terminal can fit tightly with the charging base and is not particularly easy to attract metal foreign matter, if the sensitivity corresponding to the above-mentioned charging compensation parameters is too high, it will easily cause charging interruption and affect the fast charging efficiency. Therefore, the sensitivity at this time can be appropriately reduced relative to the magnetic slow charging mode to ensure the charging effect.

[0101] In some embodiments, the protective cover includes: an NFC tag; and the detecting whether the terminal is equipped with a protective cover with an auxiliary magnetic attraction function includes:

[0102] activating the NFC chip of the terminal;

[0103] The NFC chip is used to determine whether the NFC coil of the terminal senses the NFC identifier to determine whether the protective cover is installed.

[0104] Figure 3 3 is a schematic diagram of the terminal back panel 310 and the protective cover 320, which shows the positions of the NFC coil 301 and the wireless charging coil 302 in the terminal and the positions of the magnetic attraction area 303 and the NFC logo 304 in the protective cover. Figure 3 As shown, the NFC tag 304 of the protective cover can be set at a position corresponding to the NFC coil 301 of the terminal, so as to facilitate NFC recognition by the terminal. For example, the NFC tag 304 can overlap with the NFC coil 301 of the terminal, or can be located within the sensing range of the NFC coil 301 of the terminal.

[0105] In addition, the magnetic area 303 of the protective cover 320 may be a concentric ring with the terminal wireless charging coil 302 , and the size of the magnetic area 303 is similar to that of the wireless charging coil 302 , so as to be matched with the magnetic charging stand.

[0106] In some embodiments, the method further comprises:

[0107] The identification information of whether the terminal is installed with the protective cover is saved; wherein the identification information is used to identify whether the terminal is installed with the protective cover when the terminal is in a powered-off state for charging.

[0108] In the disclosed embodiment, it is considered that the CPU (Central Processing Unit) can be started for charging when the terminal is turned off, but the NFC chip cannot be started, so it may not be possible to identify whether the protective cover is installed. Therefore, the terminal can save the identification information of whether the protective cover is installed, and when wireless charging is performed in the off state, the identification information can be directly read to determine whether the protective cover is installed.

[0109] Of course, this method has certain limitations and cannot completely guarantee accurate determination of the current terminal status. Therefore, in other embodiments, other methods that can be started in the shutdown state can also be used to identify whether the terminal is equipped with a protective cover.

[0110] For example, the terminal can determine whether the protective cover is installed by magnetic field detection. Alternatively, the terminal can communicate with the charging stand, and the charging stand identifies whether the terminal is installed with a protective cover (in this case, the charging stand can perform NFC identification), and then the charging stand notifies the terminal whether the protective cover is installed.

[0111] The present disclosure also provides a terminal charging method, including:

[0112] Enable the wireless reverse charging function of the terminal;

[0113] According to whether the terminal is equipped with the protective cover, a charging compensation parameter of a corresponding wireless reverse charging function is set.

[0114] The terminal's wireless charging coil can not only receive electrical energy to charge itself, but can also be used as a charging station to charge other terminals.

[0115] At this time, the terminal is charging another terminal, so there is no need to detect the type of the charging cradle, but only to detect whether the terminal is equipped with a protective cover, thereby setting corresponding charging compensation parameters based on whether the protective cover is installed.

[0116] It is understandable that this method can be combined with the methods of other embodiments described above. In the other embodiments described above, the terminal detects whether a protective cover is installed, and sets corresponding charging compensation parameters according to the detection results when reverse charging is performed. Of course, the terminal can also detect whether a protective cover is installed after starting the wireless reverse charging function, so as to facilitate setting more accurate charging compensation parameters.

[0117] The present disclosure also provides a protective cover, such as Figure 3 The protective cover 320 shown in FIG. 1 comprises:

[0118] Magnetic area 303; when the terminal is installed with the protective cover 320, the magnetic area 303 covers the wireless charging area of ​​the terminal; the magnetic area 303 is used to assist the terminal in magnetic charging;

[0119] Detection mark, such as Figure 3 The NFC identifier 304 in the protective cover is used to enable the terminal to identify the protective cover 320 as a protective cover with an auxiliary magnetic attraction function.

[0120] In some embodiments, the detection identifier includes: an NFC identifier;

[0121] When the terminal is installed with the protective cover, the NFC logo is located within the identifiable area of ​​the NFC coil of the terminal.

[0122] The method in the above embodiment has been introduced and will not be repeated here.

[0123] like Figure 4 As shown, the embodiment of the present disclosure further provides a charging device 400 for a terminal, the device being applied to a terminal for non-magnetic charging, comprising:

[0124] The determination module 410 is configured to detect that the terminal starts wireless charging and determine the type of the wireless charging stand;

[0125] The detection module 420 is configured to detect whether the terminal is equipped with a protective cover with an auxiliary magnetic suction function, wherein the protective cover includes a magnetic suction area covering the wireless charging area of ​​the terminal, and the magnetic suction area is used to assist the terminal in magnetic suction charging;

[0126] The first compensation module 430 is configured to set corresponding charging compensation parameters according to the type of the wireless charging seat and whether the terminal is equipped with a protective cover during the wireless charging; wherein the charging compensation parameters are used to adjust the sensitivity of foreign object detection during the charging process.

[0127] In some embodiments, the apparatus further comprises:

[0128] The setting module is configured to set a corresponding charging mode according to the type of the wireless charging seat and whether the terminal is equipped with a protective cover when performing the wireless charging.

[0129] In some embodiments, the setting module is specifically configured as follows:

[0130] If the type of the wireless charging stand is a magnetic charging stand and the terminal is equipped with the protective cover, the magnetic fast charging mode is set;

[0131] If the type of the wireless charging stand is a non-magnetic charging stand and the terminal is equipped with the protective cover, the magnetic slow charging mode is set;

[0132] If the type of the wireless charging stand is a magnetic charging stand and the terminal is not equipped with the protective cover, the normal slow charging mode is set;

[0133] If the type of the wireless charging stand is a non-magnetic charging stand and the terminal is not equipped with the protective cover, it is set to the normal fast charging mode.

[0134] In some embodiments, the sensitivity corresponding to the charging compensation parameter of the magnetic fast charging mode is lower than the sensitivity corresponding to the charging compensation parameter of the magnetic slow charging mode;

[0135] The sensitivity corresponding to the charging compensation parameter of the normal slow charging mode is higher than the sensitivity corresponding to the charging compensation parameter of the normal slow charging mode.

[0136] In some embodiments, the protective cover includes: a near field communication NFC tag; the first detection module is specifically configured as follows:

[0137] activating the NFC chip of the terminal;

[0138] It is detected whether the NFC chip senses the NFC identifier to determine whether the protective cover is installed.

[0139] In some embodiments, the apparatus further comprises:

[0140] The storage module is configured to store identification information of whether the terminal is equipped with the protective cover; wherein the identification information is used to identify whether the terminal is equipped with the protective cover when the terminal is in a powered-off state for charging.

[0141] In some embodiments, the apparatus comprises:

[0142] A startup module configured to start a wireless reverse charging function of the terminal;

[0143] The second compensation module is configured to set a charging compensation parameter of a corresponding wireless reverse charging function according to whether the terminal is equipped with the protective cover.

[0144] The present disclosure also provides the following examples:

[0145] like Figure 5 As shown, the non-magnetic wireless charging mobile phone 500 includes: a wireless charging coil 501, a wireless charging chip 502, an NFC coil 503, an NFC chip 504, a CPU 505, a storage chip 506, a charging circuit 507, a battery 508, etc.

[0146] In order to realize magnetic wireless charging for non-magnetic wireless charging mobile phones, a mobile phone case with auxiliary magnetic function can be used, which includes a magnet and an NFC TAG (NFC tag). After the mobile phone is equipped with the mobile phone case, the NFC tag and the NFC coil of the mobile phone partially overlap or the offset distance is less than a certain threshold, such as 2mm.

[0147] There are three scenarios for wireless charging, which are described below:

[0148] Usage scenario 1: Wireless charging when the phone is turned on.

[0149] like Figure 6 As shown, the following steps are included:

[0150] S601: Start wireless charging. The mobile phone is turned on and placed on the wireless charging base to start wireless charging.

[0151] S602: The mobile phone CPU notifies the NFC chip to start the identification function and determine whether there is an NFC TAG.
