[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0040] In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically limited. In the present application, the term "in some embodiments" is used to mean "used as an example, illustration or description". Any embodiment described as "in some embodiments" in the present application is not necessarily interpreted as being more preferred or more advantageous than other embodiments. In order to enable any technician in the field to implement and use the present application, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can also be implemented without using these specific details. In other examples, well-known principles and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present application obscure. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0041] The embodiments of the present application provide a charging control module, method, electronic device and computer-readable storage medium, which are described in detail below.

[0042] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the functional architecture of the charging control module provided in the embodiment of the present application. The charging control module includes a charging management module, a protocol chip and a charging chip. The charging management module is connected to the charging chip through an integrated circuit bus (Inter-Integrated Circuit, IIC, also known as I 2 C) are connected to the protocol chip and the charging chip respectively. The charging management module can be, for example, an RG520N-EU communication module, the protocol chip can be, for example, an SC2021A chip, and the charging chip can be, for example, an SC89890H chip.

[0043] The integrated circuit bus is a bidirectional two-wire synchronous serial bus that realizes effective control between integrated circuits (ICs). It only needs two wires, namely the serial data line (SDA) and the serial clock line (SCL), to transmit information between devices connected to the bus. Therefore, in the embodiment of the present application, the charging management module can be used as a host, and the protocol chip and the charging chip can be used as slaves respectively. The charging management module uses the integrated circuit bus to control the protocol chip and the charging chip. For example, the charging management module can use the integrated circuit bus to read data from the protocol chip and use the integrated circuit bus to write data to the charging chip, thereby realizing charging management.

[0044] The protocol chip is connected to the charging interface, which may be, for example, a type-C interface, or other types of interfaces, which are not limited here. The charging interface is used to connect an external device, which may be a forward charging device or a reverse charging device. A forward charging device, such as a charger, can provide power to the charging interface for forward charging. A reverse charging device, such as a mobile phone, can provide power to the mobile phone for reverse charging. The protocol chip is used to determine the target charging protocol information adapted to the external device connected to the charging interface, wherein the charging protocol may specifically be a fast charging protocol such as USB PD (USB Power Delivery, Universal Serial Bus Power Delivery), or other common charging protocols, which are not limited here. The target charging protocol information includes information such as the current size, voltage size, and protocol specifications that are compatible with the external device. The target charging protocol information can be determined through the charging protocol negotiation process between the protocol chip and the external device. Taking the external device as a charger as an example, the charger can send the charging protocols it supports to the protocol chip through the charging interface. The protocol chip analyzes the received charging protocols and selects a charging protocol from them, and feeds back the selected charging protocol to the charger, so that the charger provides power to the charging interface according to the current size, voltage size, and other information corresponding to the selected charging protocol. The current size, voltage size, protocol specifications, and other information corresponding to the charging protocol selected by the protocol chip are the target charging protocol information that is compatible with the charger, an external device. The protocol chip can store the target charging protocol information in its own preset first register for reading by the charging management module.

[0045] Therefore, the charging management module can be used to obtain the target charging protocol information stored in the protocol chip through the integrated circuit bus connected to the protocol chip. For example, the target charging protocol information can be read from the preset first register of the protocol chip. The charging management module can also be used to determine the target charging parameters of the charging chip according to the target charging protocol information. The target charging parameters include information such as the current size and voltage size adapted to the external device. The target charging parameters can be used to know how much current (for example, 2A, 4.5A, etc.) and voltage (for example, 5V, 9V, 12V, etc.) are needed for charging. The charging management module can also be used to input the target charging parameters into the charging chip through the integrated circuit bus connected to the charging chip. For example, the charging management module can write the target charging parameters into the preset second register of the charging chip to configure the charging chip.

[0046] The charging chip is connected to the battery, and the battery is a battery that needs to be charged or discharged. For example, when the external device is a forward charging device, the battery is a battery that needs to be charged, and when the external device is a reverse charging device, the battery is a battery that needs to be discharged. The charging chip can read the configured target charging parameters from its own preset second register, and then perform charging processing based on the battery according to the target charging parameters. Among them, when the external device is a forward charging device, the battery can be charged based on the power provided by the external device, for example Figure 3 As shown in the figure, when the protocol chip determines the target charging protocol information and controls the MOS (metal oxide semiconductor field effect transistor) to turn on, the power provided by the external device can be transmitted to the charging chip through VBUS (voltage bus), MOS, and VBUS / OTG (on-the-go) line in sequence, and the charging chip charges the battery under the action of V-SYS (system voltage). When the external device is a reverse charging device, the external device can be charged based on the power provided by the battery, for example Figure 3 As shown, when the protocol chip determines the target charging protocol information and controls the MOS to be turned on, the charging chip can transmit the power provided by the battery to the external device through the VBUS / OTG line, MOS, and VBUS in sequence under the action of V-SYS to charge the external device.

[0047] It can be seen that the charging control module provided in the embodiment of the present application adopts an independent protocol chip, a charging chip, and a charging management module. The charging management module controls the protocol chip and the charging chip based on the integrated circuit bus to achieve charging control, avoiding the integration of the charging control scheme in the same chip, making charging control more convenient and with a lower technical threshold, thereby reducing the chip cost and the implementation cost of the charging control scheme. In addition, the charging control module supports both forward charging and reverse charging to meet the charging needs of a variety of different scenarios.

[0048] In some embodiments of the present application, reference Figure 2 The charging control module may also include a charging metering chip, and the charging metering chip may be, for example, a CW2017BAAD chip. The charging metering chip is connected to the battery and is used to detect the battery status information of the battery in real time, such as the current battery power and the current battery temperature. The charging management module is also connected to the charging metering chip through an integrated circuit bus. For example, the charging management module may read the battery status information from the charging metering chip through the integrated circuit bus. In this way, the charging management module may report the battery status information to the upper-layer application to output the battery status information. For example, the battery status information may be displayed on a display screen associated with the upper-layer application so that the user can understand the current status of the battery in a timely manner.

[0049] In a further embodiment, the charging management module can also be used to control the end of the charging process. Specifically, the charging management module can also be used to: based on the battery status information, detect whether the preset charging end condition is met. When the external device is a forward charging device, the charging end condition may include, for example, that the current battery power is 100% (the charging end condition may also include detecting that the external device is unplugged from the charging interface, etc.), and when the external device is a reverse charging device, the charging end condition may include, for example, that the current discharge voltage of the battery is less than the preset discharge voltage (the charging end condition may also include detecting that the external device is unplugged from the charging interface, etc.); if it is detected that the charging end condition is met, control the charging chip to stop the charging process. For example, the charging management module may write the preset stop charging parameter into the preset second register of the charging chip, so that the charging chip ends the battery-based charging process according to the stop charging parameter, thereby completing the control of the entire charging cycle. The stop charging parameter may include a current value, a voltage value, etc. with a value of zero, for ending the charging process.

[0050] In some embodiments of the present application, the protocol chip can also be used to determine a target charging mode adapted to an external device, such as a forward charging mode, a reverse charging mode, etc. Specifically, the protocol chip is connected to the charging interface through a channel configuration pin (Channel Configuration, CC) (for example, Figure 3In the example, the protocol chip is connected to the charging interface through the CC1 and CC2 pins. The protocol chip is also used to determine the target charging mode adapted to the external device according to the voltage on the channel configuration pin. Taking the charging interface as the type-C interface as an example, based on the specification of the type-C interface, when the type-C interface is connected to a forward charging device such as a charger, the voltage on its channel configuration pin (at least one of the CC1 and CC2 pins) will be pulled up to VBUS, and the target charging mode at this time is the forward charging mode. When the type-C interface is connected to a reverse charging device such as a mobile phone, the voltage on its channel configuration pin (at least one of the CC1 and CC2 pins) will be pulled down to GND (Ground), and the target charging mode at this time is the reverse charging mode.

[0051] In addition, the protocol chip can also detect the positive and negative insertion of the external device relative to the charging interface through the CC1 and CC2 pins (positive insertion upward, negative insertion facing upward). For example, in the forward charging mode, it can be determined whether the external device is inserted forward or reversely relative to the charging interface based on whether the channel configuration pin whose voltage is pulled up to VBUS is the CC1 pin or the CC2 pin. For another example, in the reverse charging mode, it can be determined whether the external device is inserted forward or reversely relative to the charging interface based on whether the channel configuration pin whose voltage is pulled down to GND is the CC1 pin or the CC2 pin.

[0052] In a further embodiment, the charging management module is also used to obtain the target charging mode through the integrated circuit bus connected to the protocol chip, for example, reading the target charging mode from the preset third register of the protocol chip, and then inputting the target charging mode into the charging chip through the integrated circuit bus connected to the charging chip (for example, writing the target charging mode into the preset fourth register of the charging chip). Accordingly, the charging chip is also used to read the target charging mode from the preset fourth register, and when the target charging mode is the forward charging mode, perform charging processing from the external device to the battery according to the target charging parameters (i.e., forward charging processing), and when the target charging mode is the reverse charging mode, perform charging processing from the battery to the external device according to the target charging parameters (i.e., reverse charging processing), thereby ensuring the accurate implementation of the forward charging function and the reverse charging function.

[0053] In some embodiments of the present application, the charging control module can also realize the data communication function while realizing the charging function, for example Figure 3 In the embodiment, the charging interface can be connected to an external device through the VBUS pin to realize the charging function, and the charging interface can also be connected to an external device through the Data pin to realize the data communication function with the external device. Figure 3The charging control module also includes a data line (data minus / dataplus, DM / DP, also known as D- / D+) switching chip, and the data line switching chip can be, for example, an SGM7227 chip. The data line switching chip is connected to the charging interface, the protocol chip, and the charging management module through different data lines. For example, Figure 3 In the data line switching chip, the data line switching chip can connect to the charging management module through DM / DP, connect to the charging interface through DM1 / DP1, and connect to the protocol chip through DM2 / DP2.

[0054] The data line switching chip is used to establish a first communication connection between the charging interface and the protocol chip by using the data line DM1 / DP1 between the data line switching chip and the charging interface and the data line DM2 / DP2 between the data line switching chip and the protocol chip when detecting that an external device is plugged into the charging interface. The protocol chip determines the target charging protocol information based on the first communication connection. For example, the protocol chip can perform data communication with an external device plugged into the charging interface based on the first communication connection, complete the charging protocol negotiation process between the protocol chip and the external device, and determine the target charging protocol information.

[0055] The data line switching chip is also used to establish a second communication connection between the charging interface and the charging management module by using the data line DM1 / DP1 between the data line switching chip and the charging interface and the data line DM / DP between the data line switching chip and the charging management module after determining the target charging protocol information. Data is transmitted between the external device and the charging management module based on the second communication connection. For example, when the external device is a reverse charging device such as a mobile phone, the mobile phone can communicate data with the charging management module based on the second communication connection, thereby transmitting user data in the mobile phone to the electronic device where the charging management module is located, or transmitting user data in the electronic device where the charging management module is located to the mobile phone.

[0056] In addition, Figure 3 The charging management module can also be connected to the data line switching chip via the first selection signal line (SEL1). The charging management module is also used to send a selection signal including a preset first identifier to the data line switching chip using the first selection signal line when detecting that an external device is inserted into the charging interface, so that the data line switching chip establishes a first communication connection between the charging interface and the protocol chip. and after acquiring the target charging protocol information, using the first selection signal line to send a selection signal including a preset second identifier to the data line switching chip, so that the data line switching chip establishes a second communication connection between the charging interface and the charging management module

[0057] It can be seen that the charging control module provided in the embodiment of the present application divides the data line DM1 / DP1 between the data line switching chip and the charging interface into two. When charging protocol negotiation is required, the charging interface is switched to the protocol chip using the data line switching chip. After the target charging protocol information is determined, the charging interface is switched to the charging management module using the data line switching chip, so as not to affect data communication while charging. This design of splitting into two realizes resource sharing of the data line DM1 / DP1 between the data line switching chip and the charging interface, thereby further reducing the cost of the charging control module.

[0058] In a further embodiment, referring to Figure 3 , the charging control module also includes a Universal Serial Bus (USB) chip, and the Universal Serial Bus chip can be, for example, an AW35710 chip. The charging management module is also connected to the charging interface through the Universal Serial Bus chip, so that data transmission between the external device and the charging management module is performed based on the Universal Serial Bus chip or the second communication connection. It should be noted that since the data line DM1 / DP1 between the data line switching chip and the charging interface belongs to the data line in USB2.0, the communication based on the USB2.0 specification can be realized through the second communication connection, but the communication based on the USB3.0, 3.1 and other specifications cannot be realized. Therefore, the embodiment of the present application also sets a Universal Serial Bus chip to realize the communication based on the USB3.0, 3.1 and other specifications. Taking USB3.0 as an example, the Universal Serial Bus chip can be connected to the charging interface through the two pairs of differential signal lines SS-TX / RX1 and SS-TX / RX2, so as to carry out the USB3.0 specification communication based on the two pairs of differential signal lines SS-TX / RX1 and SS-TX / RX2, thereby realizing higher-speed data communication.

[0059] In addition, Figure 3 In the embodiment, the charging management module can also be connected to the universal serial bus chip through the second selection signal line (SEL2). The charging management module is also used to send a selection signal including a preset third identifier to the universal serial bus chip using the second selection signal line when communication based on USB3.0, 3.1 and other specifications is required, so as to use the two pairs of differential signal lines SS-TX / RX1 and SS-TX / RX2 between the universal serial bus chip and the charging interface to achieve communication based on USB3.0, 3.1 and other specifications. When communication based on USB3.0, 3.1 and other specifications is not required, the selection signal including the preset third identifier is not sent to the universal serial bus chip.

[0060] In order to better implement the charging control module in the embodiment of the present application, based on the charging control module, a charging control method is also provided in the embodiment of the present application. The charging control method is applied to the charging management module in the charging control module. The charging management module is connected to the protocol chip and the charging chip respectively through the integrated circuit bus. Figure 4 As shown, the charging control method includes:

[0061] 401. Obtain target charging protocol information determined by the protocol chip through an integrated circuit bus connected to the protocol chip;

[0062] 402. Determine a target charging parameter of the charging chip according to the target charging protocol information;

[0063] 403. Input the target charging parameters into the charging chip through the integrated circuit bus connected to the charging chip, so that the charging chip performs charging processing according to the target charging parameters.

[0064] The charging control method provided in the embodiment of the present application adopts an independent protocol chip, a charging chip, and a charging management module. The charging management module controls the protocol chip and the charging chip based on an integrated circuit bus to achieve charging control, thereby avoiding integrating the charging control scheme into the same chip, thereby reducing the chip cost and the implementation cost of the charging control scheme.

[0065] In addition to the charging control module and charging control method described above, the embodiment of the present application also provides an electronic device that integrates any charging control module provided in the embodiment of the present application. The electronic device may be, for example, a MIFI (Mobile WIFI) device. The MIFI device is a portable broadband wireless device that integrates dialing, routing and access functions.
