Description

TECHNICAL FIELD

[0002] In the related art, electronic devices such as mobile phones and tablets support high-power (for example, greater than 30W) charging, and the requirement for charging speed is increasingly high. However, slow charging often occurs at present. For example, when a charging architecture including a Power Management Integrated Circuit (PMIC) charging chip and a slave charger is adopted, when an abnormality occurs in the slave charger in the slave charger in the master charging chip, the slave charger cannot be switched to continue charging, and only the PMIC charger can be converted to perform charging; and the charging power supported by the PMIC charger itself is not high, which greatly reduces the charging speed of the electronic device and brings a poor experience to the user.

[0034] In the scheme, the switching circuit is configured to switch the controlled switch module from the second switch state to the first switch state when the first charging module is in normal charging, so as to enable the second charging module to enter a non-charging state.

[0035] According to a second aspect of the embodiments of the present disclosure, a charging method is provided, which is applied to a charging device, the charging device comprising: a charging circuit; the charging circuit comprising: N charging modules; wherein the N charging modules at least comprise: a first charging module and a second charging module; wherein N is an integer greater than 1; the method comprising:

[0056] It should be understood that the foregoing general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0068] The exemplary embodiments will be described in detail herein below with reference to the drawings. In the following description, the same drawings reference numbers are used to denote the same elements throughout the several several views. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0069] As Figure 1As shown, a charging architecture is disclosed; the charging architecture comprises a PMIC charging chip and a master-slave charging chip, the master-slave charging chip comprises a master charging chip and a slave charging chip; the master charging chip, the slave charging chip and the PMIC charging chip are connected in parallel between a charger and a battery. Here, the charging power of the PMIC charging chip per unit time is less than the charging efficiency of the master charging chip or the slave charging chip per unit time. During the charging process, the master-slave charging chip can charge the battery in the constant current (CC) charging phase; the PMIC charging chip can charge the battery in the constant voltage (CV) charging phase.

[0070] However, due to the fixed peripheral configuration circuit of the master-slave charging chip, when the master charging chip stops working, the slave charging chip also stops working. If the master-slave charging chip stops working at the same time when the master charging chip fails or the like during the CC charging phase, the charging power will be low and the charging speed will be slow if the PMIC charging chip is switched to charge.

[0071] In the embodiment of the present disclosure, a charging device is provided, which can automatically enter the charging state and charge when the first charging module (such as the master charging chip) fails to charge, so that the charging device can also charge based on one charging module, thereby speeding up the charging.

[0072] Figure 2 A block diagram of a charging device according to an exemplary embodiment is shown as follows, Figure 2 As shown, the charging device comprises:

[0073] The charging circuit 11 comprises N charging modules; wherein the N charging modules at least comprise a first charging module 111 and a second charging module 112.

[0074] The switching circuit 12 is connected to the first charging module 111 and the second charging module 112.

[0075] The switching circuit 12 is configured to control the first charging module 111 to enter the charging state or control the second charging module 112 and the first charging module 111 to enter the charging state when the first charging module 111 charges normally; or control the second charging module 112 to enter the charging state when the first charging module 111 charges abnormally.

[0076] The charging device described in this embodiment can be applied to a terminal, which can be a mobile terminal or a fixed terminal. For example, the terminal can be a mobile phone, computer, laptop, or a wireless charging receiver or transmitter.

[0077] In this embodiment, both the first charging module and the second charging module can be any type of charging chip or a module with charging functionality. The first charging module and the second charging module may be of the same or different types.

[0078] In one embodiment, the first charging module may be a main charging module, and the second charging module may be a slave charging module.

[0079] like Figure 3 As shown, in another embodiment, the first charging module can be a master charging chip, and the second charging module can be a slave charging chip.

[0080] In one embodiment, the switching circuit is used to control the second charging module to charge and control the first charging module to stop charging when a charging abnormality occurs in the first charging module.

[0081] In some embodiments, the N charging modules can also be three or more charging modules; when one charging module experiences a charging abnormality, at least one of the other N-1 charging modules will enter the charging state. Thus, in this embodiment, when one charging module among the N charging modules experiences a charging abnormality, one or more of the other N-1 charging modules can be charged, maintaining continuous charging of the wireless charging device and improving charging efficiency.

[0082] For example, there may be one first charging module and one second charging module; or one first charging module and multiple second charging modules; or multiple first charging modules and one second charging module; or multiple first charging modules and multiple second charging modules. Here, one first charging module corresponds to one second charging module, or one first charging module corresponds to multiple second charging modules.

[0083] In this embodiment, when the first charging module is charging normally, the first charging module can be controlled to enter the charging state, or the second charging module can be controlled to enter the charging state together with the first charging module. That is, the second charging module is a slave charging module of the first charging module. When the first charging module is charging normally, the second charging module can charge according to the first charging module or the first charging module can charge independently. And when the first charging module is charging abnormally, the second charging module can be controlled to charge. That is, when the first charging module cannot charge, it can also charge according to the second charging module.

[0084] Thus, in this embodiment, when the first charging module malfunctions, the second charging module can replace the first charging module to form the main charging module 2 for charging. This reduces the possibility of the second charging module also stopping working when the first charging module malfunctions, resulting in low charging efficiency and slow charging time. This can greatly improve charging efficiency and reduce charging time.

[0085] like Figure 4 As shown, the switching circuit 12 includes:

[0086] The controlled switch module 121 is connected to the first charging module 112 and the second charging module 112;

[0087] The control module 122 is connected to the controlled switch module 121 and is used to switch the controlled switch module 121 from a first switch state to a second switch state when the first charging module 111 experiences a charging abnormality, so that the second charging module 112 enters the charging state.

[0088] If the controlled switch module 121 is in the first switch state, and the first charging module 111 experiences a charging abnormality, the second charging module 112 enters a non-charging state.

[0089] In one embodiment, when the first charging module experiences a charging abnormality, the controlled switch module is in a first switching state; only when the control module of the switching circuit receives a first control signal will the switching state of the controlled switch module be switched to a second switching state.

[0090] The control module 122 here typically controls the charging device's charging operations, for example, controlling the connection switching between the terminals of the controlled switch module. The control module can be a module including one or more processing chips or processors. Alternatively, the control module can also be a control circuit with signal processing capabilities; the control circuit may include a control chip or controller, etc.

[0091] The control signal sent by the control module herein can be a high-level signal or a low-level signal. For example, the first control signal sent is a high-level signal, or the second control signal sent is a low-level signal. The high-level signal and the low-level signal are relative.

[0092] In the embodiments of the present disclosure, the switching circuit can be used to switch the switch state of the controlled switch module, so that when the first charging module has a charging abnormality, the second charging module that cannot be charged originally is changed to be able to charge the wireless charging device, thereby realizing that the wireless charging device charges according to the second charging module, and improving the charging efficiency of the wireless charging device and reducing the charging time.

[0093] Of course, in other embodiments, the control module can also switch the switch state of the controlled switch module to the first switch state based on the second control signal.

[0094] As shown in Figure 5 The charging device further includes an overvoltage protection circuit 13.

[0095] The controlled switch module 121 includes a first controlled switch 1211.

[0096] The overvoltage protection end of the first charging module 111 is connected to the input end of the overvoltage protection circuit 13.

[0097] The overvoltage protection end of the second charging module 112 is connected to the first end of the first controlled switch 1211, the second end of the first controlled switch 1211 is connected to the input end of the overvoltage protection circuit 13, and the third end of the first controlled switch 1211 is connected to the output end of the overvoltage protection circuit 13.

[0098] When the first charging module 111 has a charging abnormality, the connection between the first end and the second end of the first controlled switch 1211 is turned on, and the second charging module 112 enters a charging state.

[0099] In one embodiment, when the controlled switch module is in the second switch state, at least the connection between the first end and the second end of the first controlled switch is turned on.

[0100] In one embodiment, when the overvoltage protection end of the first charging module is connected to the input end of the overvoltage protection circuit and the overvoltage protection end of the second charging module is connected to the output end of the overvoltage protection circuit, the first charging module is a master charging module, and the second charging module is a slave charging module.

[0101] The overvoltage protection circuit herein is used to stabilize the input voltage value within a predetermined range and output.

[0102] In one embodiment, as shown in Figure 3 the overvoltage protection circuit includes a metal oxide semiconductor field effect (MOS) tube and a diode; the anode of the diode is connected to the drain of the MOS tube, and the cathode of the diode is connected to the source of the MOS tube; the source of the MOS tube is the input end of the overvoltage protection circuit, and the drain of the MOS tube is the output end of the overvoltage protection circuit. When the output voltage of the overvoltage protection circuit is higher than a predetermined value, the diode is turned on, and the output voltage is clamped, so that the output voltage is limited within a predetermined range. Of course, in other embodiments, the overvoltage protection circuit can be in any circuit form, as long as it can stabilize the input voltage within a predetermined range and output it. Here, the components included in the overvoltage protection circuit and the connection mode of each component are not limited.

[0103] In one application scenario, the input end of the overvoltage protection circuit is the front stage of the overvoltage protection circuit, and the output end of the overvoltage protection circuit is the rear stage of the overvoltage protection circuit.

[0104] The overvoltage protection end here is used for overvoltage protection of the input voltage of the first charging module or the second charging module. In one embodiment, as shown in Figure 3 the overvoltage protection end is the VAC pin of the charging chip; the VAC pin is used to detect the size of the input alternating current.

[0105] Here, the first controlled switch is a single-pole double-throw switch. The first controlled switch includes at least three terminals. Of course, in other embodiments, the first controlled switch can also be other types of switches, as long as it can switch between the input end or the output end of the overvoltage protection circuit.

[0106] Here, the second charging module enters a charging state, that is, the second charging module charges the connected battery.

[0107] Here, the overvoltage protection end of the second charging module is connected to the first terminal of the first controlled switch, the second terminal of the first controlled switch is connected to the input end of the overvoltage protection circuit, and the third terminal of the first controlled switch is connected to the output end of the overvoltage protection circuit. When the connection between the first terminal and the second terminal of the first controlled switch is turned on, the connection between the overvoltage protection end of the second charging module and the input end of the overvoltage protection circuit is turned on; when the connection between the first terminal and the third terminal of the first controlled switch is turned on, the connection between the overvoltage protection end of the second charging module and the output of the overvoltage protection circuit is turned on.

[0108] In related technologies, as shown in Figure 3As shown, if the second charging module is directly connected to the output end of the overvoltage protection circuit, when the first charging module has charging abnormality, the second charging module will also stop working; thus, the charging efficiency is greatly reduced.

[0109] In the embodiments of the present disclosure, when the first charging module has charging abnormality, the first end and the second end of the first controlled switch are connected, and the connection between the overvoltage protection end of the second charging module and the input end of the overvoltage protection circuit is turned on, so that the second charging module replaces the first charging module to charge, thereby reducing the situation that the second charging module also stops working due to the charging abnormality of the first charging module in the related art, and the charging efficiency of the charging device is not high and the charging time is too slow, greatly improving the charging efficiency and reducing the charging time.

[0110] In some embodiments, when the first charging module has charging normality, the connection between the first end and the third end of the first controlled switch is turned on, and the second charging module enters a non-charging state. Here, the controlled switch module is in a second switch state.

[0111] Here, the connection between the first end and the third end of the first controlled switch is turned on, that is, the connection between the overvoltage protection end of the second charging module and the output end of the overvoltage protection circuit is turned on. At this time, in the charging circuit, the first charging module mainly charges the battery connected thereto.

[0112] Thus, in the embodiments of the present disclosure, whether the first charging module or the second charging module is used for charging can be selected according to whether the first charging module has abnormal charging. For example, when the first charging module has charging abnormality, the charging circuit switches to the second charging module for charging; for another example, when the first charging module has charging normality, the charging circuit switches to the first charging module for charging. Thus, when one of the first and second charging modules in the charging circuit has charging abnormality such as damage or communication abnormality, the charging efficiency of the charging device can be basically maintained.

[0113] In other embodiments, when the first charging module has charging normality, the connection between the first end and the third end of the first controlled switch is turned on, and the second charging module maintains a charging state. Here, if the first charging module does not have charging abnormality, and the second charging module is also not damaged, the second charging module can still be used for charging; only the charging power of the second charging module is determined based on the charging power of the first charging module.

[0114] For example, in one embodiment, when the first charging module is in normal charging, the first controlled switch is turned on between the first end and the third end, and the second charging module maintains the charging state but reduces the charging power of the second charging module. At this time, as shown in Figure 3 the synchronization signal output end (such as the SYNC_OUT pin) of the first charging module is connected to the synchronization signal input end (such as the SYNC_IN pin) of the second charging module.

[0115] Here, the charging information of the first charging module can be sent to the second charging module based on the connection between the synchronization signal output end and the synchronization signal input end; in this way, the second charging module can be informed of the charging state or the current charging power of the first charging module.

[0116] For example, the charging information can be a high-level signal or a low-level signal; wherein the high-level signal is used to indicate that the first charging module is in normal charging, and the low-level signal is used to indicate that the first charging module is in abnormal charging. Here, the high level and the low level are relative, and the voltage of the high level is higher than the voltage of the low level.

[0117] For example, the charging information can be a predetermined level signal; wherein the predetermined level signal is used to indicate the charging power of the first charging module.

[0118] In some embodiments, as shown in Figure 6 the controlled switch module 121 further comprises a second controlled switch 1212 and a third controlled switch 1213; wherein,

[0119] the first end of the second controlled switch 1212 is used to connect with the positive electrode of the battery, the second end of the second controlled switch 1212 is connected with the positive electrode end of the battery of the second charging module 112, and the third end of the second controlled switch 1212 is connected with the positive electrode end of the battery of the first charging module 111;

[0120] the first end of the third controlled switch 1213 is used to connect with the negative electrode of the battery, the second end of the third controlled switch 1213 is used to connect with the negative electrode end of the battery of the second charging module 112, and the third end of the third controlled switch 1213 is connected with the negative electrode end of the battery of the first charging module 111;

[0121] when the first charging module 111 is in abnormal charging, the first end and the second end of the second controlled switch 1212 are connected, and the first end and the second end of the third controlled switch 1213 are connected, and the second charging module 112 detects the charging voltage of the battery.

[0122] In one embodiment, the controlled switch module is in the second switch state, at least including: the connection between the first end and the second end of the second controlled switch is conducted and the connection between the first end and the second end of the third controlled switch is conducted.

[0123] The second controlled switch and the third controlled switch herein can be single-pole double-throw switches. The second controlled switch and the third controlled switch include at least three terminals. Of course, in other embodiments, the second controlled switch and the third controlled switch can also be other types of switches, as long as the second controlled switch can switch between the positive electrode of the battery of the first switch module and the positive electrode of the battery of the second switch module, and as long as the third controlled switch can switch between the negative electrode of the battery of the first switch module and the negative electrode of the battery of the second switch module.

[0124] The positive electrode terminal and the negative electrode terminal herein are used to detect the charging voltage of the battery. In one embodiment, as shown in FIG. 1, the positive electrode terminal is the BATP pin of the charging chip, and the negative electrode terminal is the BATN pin of the charging chip. Figure 3 Or Figure 6 As shown in FIG. 1, the positive electrode terminal is the BATP pin of the charging chip, and the negative electrode terminal is the BATN pin of the charging chip.

[0125] The battery herein is the battery of the first charging module or the second charging module; the first charging module or the second charging module is connected to the battery based on the VBAT pin. In an actual application, the first charging module enters the charging state, that is, the first charging module charges the battery; the second charging module enters the charging state, that is, the second charging module charges the battery.

[0126] The connection between the first end and the second end of the second controlled switch and the connection between the first end and the second end of the third controlled switch herein are the connection between the positive electrode terminal of the second charging module and the positive electrode of the battery and the connection between the negative electrode terminal of the second charging module and the negative electrode of the battery; and the second switch module can be used to detect the charging voltage of the battery.

[0127] In the embodiments of the present disclosure, when the first charging module has a charging abnormality, the connection between the first end and the second end of the second controlled switch and the connection between the first end and the second end of the third controlled switch are conducted, so that the second switch module can detect the charging voltage of the battery; thereby the safety of charging the battery by the second charging module can be improved.

[0128] In other embodiments, if the first charging module has a charging normality, the connection between the first end and the third end of the second controlled switch and the connection between the first end and the third end of the third controlled switch are conducted, and the first charging module detects the charging voltage of the battery.

[0129] The connection between the first end and the third end of the second controlled switch and the connection between the first end and the third end of the third controlled switch are in conduction, that is, the connection between the positive electrode end of the first charging module and the positive electrode of the battery and the connection between the negative electrode end of the first charging module and the negative electrode of the battery are in conduction; and the first switch module can be used to detect the charging voltage of the battery.

[0130] In the embodiment of the present disclosure, when the first charging module is in normal charging, the connection between the first end and the third end of the second controlled switch and the connection between the first end and the third end of the third controlled switch are in conduction, so that the first charging module can detect the charging voltage of the battery; thereby the safety of the battery charging by the first charging module can be improved.

[0131] Please refer again to Figure 6 In some embodiments, the controlled switch module 121 further comprises a fourth controlled switch 1214 and a fifth controlled switch 1215; wherein,

[0132] The first end of the fourth controlled switch 1214 is connected with the second charging module 112, the second end of the fourth controlled switch 1214 is suspended, and the third end of the fourth controlled switch 1214 is used to be connected with the first resistor;

[0133] The first end of the fifth controlled switch 1215 is connected with the first charging module 111, and the second end of the fifth controlled switch 1215 is suspended.

[0134] When the first charging module 111 is in charging abnormality, the connection between the first end and the second end of the fourth controlled switch 1214 and the connection between the first end and the second end of the fifth controlled switch 1215 are in conduction; or, the connection between the first end and the third end of the fourth controlled switch 1214 and the connection between the first end and the second end of the fifth controlled switch 1215 are in conduction.

[0135] In one embodiment, the controlled switch module is in the second switch state, at least comprising:

[0136] The connection between the first end and the second end of the fourth controlled switch and the connection between the first end and the second end of the fifth controlled switch are in conduction; or, the connection between the first end and the third end of the fourth controlled switch and the connection between the first end and the second end of the fifth controlled switch are in conduction.

[0137] The first end of the fourth controlled switch 1214 is connected with the second charging module 112, that is, the first end of the fourth controlled switch 1214 is connected with a predetermined end of the second charging module 112; when the predetermined end of the second charging module is connected with resistors of different resistance values in conduction, the different I2C addresses of the second charging module are configured. Here, the I2C address is used to identify whether the second charging module is a master charging module or a slave charging module.

[0138] The first end of the fifth controlled switch 1215 is connected with the first charging module 111, that is, the first end of the fifth controlled switch 1215 is connected with a predetermined end of the first charging module 111; when the predetermined end of the first charging module is connected with resistors of different resistance values in conduction, the different I2C addresses of the first charging module are configured. Here, the I2C address is used to identify whether the first charging module is a master charging module or a slave charging module.

[0139] In an embodiment, as shown in Figure 3 The predetermined end is CDRVL_ADDRMS of the charging chip.

[0140] The connection between the first end and the second end of the fourth controlled switch is in conduction, and the connection between the first end and the second end of the fifth controlled switch is in conduction, that is, the predetermined end of the second charging module is suspended and the predetermined end of the first charging module is suspended. In this way, the charging device is in a single charging module charging state; the single charging module is only one charging module in all charging modules of the charging device for charging. In the example, the single charging module charging is charging according to the second charging module.

[0141] The connection between the first end and the third end of the fourth controlled switch is in conduction, and the connection between the first end and the second end of the fifth controlled switch is in conduction, that is, the predetermined end of the second charging module is connected with the first resistor and the predetermined end of the first charging module is suspended. In this way, the charging device is in a single charging module charging state of the second charging module. Here, the first resistor is used to configure the I2C address of the second charging module as a master charging module.

[0142] In the embodiments of the present disclosure, the charging device can be in a single charging module charging state by suspending the predetermined ends of the first charging module and the second charging module; or, by suspending the first charging module and connecting the second charging module with a predetermined impedance first resistor, the single charging module charging state of the second charging module charging is determined. In this way, the peripheral configuration of switching the second charging module to a master charging module when the first charging module appears abnormal charging can be improved.

[0143] Of course, in other embodiments, the charging device further comprises a second resistor;

[0144] The third terminal of the fifth controlled switch is connected with the second resistor;

[0145] When the first charging module is in normal charging, the connection between the first terminal and the third terminal of the fourth controlled switch is turned on, and the connection between the first terminal and the third terminal of the fifth controlled switch is turned on;

[0146] Or,

[0147] When the first charging module is in normal charging, the connection between the first terminal and the second terminal of the fourth controlled switch is turned on, and the connection between the first terminal and the second terminal of the fifth controlled switch is turned on;

[0148] Or,

[0149] When the first charging module is in normal charging, the connection between the first terminal and the second terminal of the fourth controlled switch is turned on, and the connection between the first terminal and the third terminal of the fifth controlled switch is turned on.

[0150] Here, the connection between the first terminal and the third terminal of the fourth controlled switch and the connection between the first terminal and the third terminal of the fifth controlled switch are that the predetermined terminal of the second charging module is connected with the first resistor and the predetermined terminal of the first charging module is connected with the second resistor. In this way, in the present example, the first charging module and the second charging module are used for charging together; the first charging module is the master charging module, and the second charging module is the slave charging module. Here, the predetermined terminal of the first charging module is connected with the first resistor to configure the identity of the first charging module as the master charging module, and the predetermined terminal of the second charging module is connected with the first resistor to configure the identity of the second charging module as the slave charging module.

[0151] Here, the connection between the first terminal and the second terminal of the fourth controlled switch and the connection between the first terminal and the second terminal of the fifth controlled switch are that the predetermined terminal of the second charging module is suspended and the predetermined terminal of the first charging module is suspended. In this way, the charging device is in a single charging module charging state. In the present example, the single charging module charging is charging according to the first charging module.

[0152] Here, the connection between the first terminal and the second terminal of the fourth controlled switch and the connection between the first terminal and the third terminal of the fifth controlled switch are that the predetermined terminal of the second charging module is suspended and the predetermined terminal of the first charging module is connected with the second resistor. In this way, the charging device is in a single charging module charging state of the first charging module. Here, the second resistor is used to configure the I2C address of the first charging module as the master charging module.

[0153] Here, the resistance of the first resistor is different from the resistance of the second resistor. For example, as shown in Figure 3 , the resistance of the first resistor is 39 kilo-ohms, and the resistance of the second resistor is 18 kilo-ohms.

[0154] In this way, in the embodiments of the present disclosure, when the first charging module is in normal charging, the charging diversification configuration can be realized through different configuration modes of the predetermined end of the first charging module and the second charging module. For example, whether the predetermined end of the first charging module and the second charging module is suspended determines whether only the first charging module is used for charging or the first charging module and the second charging module are used for charging together; for another example, the identity of the master and slave charging modules when the first charging module and the second charging module are used for charging together is determined by connecting different resistors to the predetermined end of the first charging module and the second charging module.

[0155] Please refer again to Figure 7 In some embodiments, the synchronization signal output end of the first charging module 111 is connected with the synchronization signal input end of the second charging module 112.

[0156] In the embodiments of the present disclosure, if the first charging module and the second charging module are both used for charging, the first charging module can send a synchronization signal to the second charging module through the synchronization signal input end, wherein the synchronization signal is used to indicate the power consumption of the second charging module for charging the battery. Here, the second charging module receives the synchronization signal based on the synchronization signal input end. Alternatively, if one of the first charging module and the second charging module is used for charging, the first charging module does not need to send a synchronization signal to the second charging module.

[0157] Please refer again to Figure 4 In some embodiments, the switching circuit 12 is configured to switch the controlled switch module 121 from the second switch state to the first switch state when the first charging module 111 is in normal charging, so as to make the charging module enter the non-charging state.

[0158] In one embodiment, the controlled switch module in the first switch state at least includes one of the following:

[0159] The connection between the first end and the third end of the first controlled switch is conducted;

[0160] The connection between the first end and the third end of the second controlled switch is conducted, and the connection between the first end and the third end of the third controlled switch is conducted;

[0161] The connection between the first end and the third end of the fourth controlled switch is conducted, and the connection between the first end and the second end of the fifth controlled switch is conducted.

[0162] In the embodiments of the present disclosure, when the first charging module is normal, it is considered that the first charging module recovers to normal charging. At this time, the second charging module stops charging the wireless charging device, and the first charging module is used for single charging again.

[0163] Please refer to Figure 6 In some embodiments, the control module 122 is configured to send a first control signal to the controlled switch module 121 if the first charging module 111 is abnormal.

[0164] The controlled switch module 121 conducts the connection between the first end and the second end of at least one of the first controlled switch 1211, the second controlled switch 1212, the third controlled switch 1213, the fourth controlled switch 1214 and the fifth controlled switch 1215 based on the first control signal.

[0165] Alternatively,

[0166] The controlled switch module 121 conducts the connection between the first end and the second end of at least one of the first controlled switch 1211, the second controlled switch 1212, the third controlled switch 1212 and the fifth controlled switch 1215, and conducts the connection between the first end and the third end of the fourth controlled switch 1214 based on the first control signal.

[0167] For example, in an embodiment, the first control signal is a high-level signal, which is used to control the connection between the first end and the second end of each controlled switch.

[0168] The first controlled switch, the second controlled switch, the third controlled switch, the fourth controlled switch and the fifth controlled switch all include four terminals.

[0169] For example, in an embodiment, the fourth terminal of the first controlled switch is connected with the control module, the fourth terminal of the second controlled switch is connected with the control module, the fourth terminal of the third controlled switch is connected with the control module, the fourth terminal of the fourth controlled switch is connected with the control module, and the fourth terminal of the fifth controlled switch is connected with the control module.

[0170] For example, in another embodiment, as Figure 7As shown, the fourth end of the first controlled switch, the fourth end of the second controlled switch, the fourth end of the third controlled switch, the fourth end of the fourth controlled switch, and the fourth end of the fifth controlled switch are respectively used for connecting with a general input and output interface (GPIO) of the charging device. The GPIO interface herein is connected with the control module. In this way, in the present example, the switching of each end of the first controlled switch, the second controlled switch, the third controlled switch, the fourth controlled switch, and the fifth controlled switch can be controlled by the control signal received through the GPIO interface.

[0171] The GPIO interface herein can include a first pin and a second pin. In one embodiment, as shown in FIG. 6, the first pin (GPIO_0) of the GPIO interface is connected with the first controlled switch, the second controlled switch, the third controlled switch, and the fourth controlled switch; and the second pin (GPIO_1) of the GPIO interface is connected with the fifth controlled switch. Figure 5 As shown, the first controlled switch, the second controlled switch, the third controlled switch, and the fourth controlled switch are respectively connected with the first pin (GPIO_0) of the GPIO interface; and the fifth controlled switch is connected with the second pin (GPIO_1) of the GPIO interface. In this way, the first controlled switch, the second controlled switch, the third controlled switch, and the fourth controlled switch together can be controlled respectively from the fifth controlled switch.

[0172] In the embodiments of the present disclosure, when the first charging module has a charging abnormality, the first control signal sent by the control module can be used to control the connection between the first end and the second end of the first controlled switch to be conductive, so that the second charging module is connected to the input end of the overvoltage protection circuit to enable the second charging module to charge; or the first control signal sent by the control module can be used to control the connection between the first end and the second end of the second controlled switch and the third controlled switch to be conductive, so that the second charging module detects the charging voltage of the battery; or the first control signal sent by the control module can be used to control the connection between the first end and the second end of the third controlled switch and the fourth controlled switch to be conductive, so as to perfect the peripheral configuration of the second charging module for charging. In this way, the second charging module can replace the first charging module to continue charging, thereby improving the charging efficiency of the charging module and reducing the charging time.

[0173] For example, in an application scenario, the first controlled switch, the second controlled switch, the third controlled switch, and the fourth controlled switch are respectively connected with the first pin (GPIO_0) of the GPIO interface, and the fifth controlled switch is connected with the second pin (GPIO_1) of the GPIO interface; in this application scenario, a specific control logic of the charging device is disclosed. As shown in FIG. 7, the steps of the control logic are as follows: Figure 8

[0174] Step S601: Determine whether the first charging module and the second charging module have normal communication; if yes, execute step S602; if no, execute step S604;

[0175] Step S602: Set GPIO_0 to output low voltage and GPIO_1 to output low voltage;​

[0176] Here, the high level is used to control the connection between the first end and the third end of each controlled switch to be conductive, and the low level is used to control the connection between the first end and the second end of each controlled switch to be conductive

[0177] In an optional embodiment, the GPIO_0=0 and the GPIO_1=1.

[0178] Step S603: Determine whether the first charging module and the second charging module are normally charging.

[0179] Step S604: Determine whether the first charging module is normally charging; if yes, execute step S605; if no, execute step S607.

[0180] Step S605: Set the GPIO_0 to output a high level and the GPIO_1 to output a low level.

[0181] In an optional embodiment, the GPIO_0=1 and the GPIO_1=0.

[0182] Step S606: Determine that the first charging module is normally charging and the second charging module is stopped charging.

[0183] Step S607: Determine whether the second charging module is normally communicating; if yes, execute step S608; if no, execute step S610.

[0184] Step S608: Set the GPIO_0 to output a low level and the GPIO_1 to output a high level.

[0185] In an optional embodiment, the GPIO_0=0 and the GPIO_1=1.

[0186] Step S609: Determine that the second charging module replaces the first charging module to charge.

[0187] Step S610: Set the GPIO_0 to output a low level and the GPIO_1 to output a low level.

[0188] In an optional embodiment, the GPIO_0=0 and the GPIO_1=0.

[0189] Step S611: Determine that the first charging module and the second charging module are charging simultaneously.

[0190] In this way, in the present example, different level signals output by the first pin and the second pin of the GPIO can be set to control the switching between the ends of each controlled switch, thereby controlling the charging device to be in different charging states.

[0193] Alternatively,

[0194] The controlled switch module 121 is configured to turn on the connection between the first end and the third end of at least one of the first controlled switch 1211, the second controlled switch 1212, the third controlled switch 1212 and the fifth controlled switch 1215, and turn on the connection between the first end and the second end of the fourth controlled switch 1214 based on the second control signal.

[0196] The high-level signal herein is used to control the connection between the first end and the third end of each controlled switch to be turned on, and the low-level signal herein is used to control the connection between the first end and the second end of each controlled switch to be turned on.

[0197] In the embodiments of the present disclosure, when the first charging module is in normal charging state, the connection between the first end and the third end of the first controlled switch, the second controlled switch and the third controlled switch can be turned on, and when the second charging module is in loss or communication abnormality, the charging can still be performed through the first charging module, so as to basically maintain the charging efficiency of the charging device. Moreover, the connection between the first end and the second end of the fourth controlled switch and the fifth controlled switch can be turned on to indicate that the charging device is for charging of a single charging module.

[0198] In other embodiments, the control module is further configured to send a third control signal to the controlled switch module when the first charging module is in normal charging state and it is determined that the second charging module can work normally;

[0199] The controlled switch module turns on the connection between the first end and the third end of the first controlled switch, the second controlled switch, the third controlled switch, the fourth controlled switch and the fifth controlled switch based on the third control signal.

[0200] In an embodiment, the third control signal is a low-level signal.

[0201] In the embodiments of the present disclosure, the first charging module and the second charging module work in parallel for charging, so that the charging efficiency of the charging module can be greatly improved and the charging time can be reduced.
