[0002] Charging chips are usually placed inside electronic devices to manage the battery charging process. For example, there is a charging conversion efficiency, which refers to the efficiency of converting electrical energy into chemical energy stored in the battery during the charging process. The charging chip carries many functions. During the charging process, especially during fast charging, a large amount of heat will be generated inside the electronic device, resulting in a high temperature rise in the electronic device body. If the temperature rise of the electronic device body is too high, it will not only affect the safety performance of the battery, but also reduce the charging speed of the battery, resulting in a poor charging experience for users.

[0088] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0089] It can be understood that the terms "each", "multiple", and "any" used in the embodiments of the present application include two or more, each refers to each of the corresponding multiple, and any refers to any one of the corresponding multiple. For example, the multiple words include 10 words, and each word refers to each of the 10 words, and any word refers to any one of the 10 words.

[0090] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0091] Before executing the embodiments of the present application, the terms involved in the embodiments of the present application are first explained.

[0092] Type-C interface: also known as USB (Universal Serial Bus)-C interface, is a new connection standard developed by USB-IF (USB Implementers Forum) for connecting electronic devices and chargers, including Type-C plugs and Type-C female sockets.

[0093] PMU (Power Management Unit) is a highly integrated power management solution for portable applications. It integrates several traditional discrete power management chips, such as low-dropout linear regulators (LDOs) and direct-current direct-current converters (DC / DC), into the PMU to achieve higher power conversion efficiency, lower power consumption, and fewer components to adapt to reduced board space and reduce costs.

[0094] SoC (System on Chip), also known as system on chip, is a dedicated integrated circuit that contains all the contents of a complete system and embedded software.

[0095] The battery protection board is an integrated circuit board that protects rechargeable batteries (generally lithium batteries).

[0096] The Vbus (Voltage Bus) power line is a circuit line defined in the USB standard, representing the voltage bus in the USB interface. In a USB connection, the Vbus power line carries the power supply signal and provides the required power for the connected electronic devices.

[0097] TVS (Transient Voltage Suppressor) is an overvoltage protection device with bidirectional voltage stabilization characteristics and bidirectional negative resistance characteristics, similar to a varistor. TVS is used in various AC and DC power supply circuits to suppress instantaneous overvoltage. When a surge pulse voltage appears in the protected circuit, the bidirectional breakdown diode can quickly break down from a high resistance state to a low resistance state, shunting and clamping the surge voltage, thereby protecting the components in the circuit from being damaged by the instantaneous surge pulse voltage.

[0098] PMID is the output voltage in boost mode. In the absence of front-end USB or adapter power supply, the output voltage in boost mode is fixed at 5V and can be adjusted through REG0A.

[0099] VSYS, as the abbreviation of SYSTEM, usually refers to the system power supply of platform solutions (such as MTK).

[0100] Q4 usually refers to a specific electronic component in a circuit, and its specific role depends on its position and function in the circuit.

[0101] ‌With the popularity of mobile devices, fast charging technology has gradually become the focus of users. Compared with traditional charging methods, fast charging technology greatly shortens the charging time of electronic device batteries, allowing users to use electronic devices in a short time, thereby helping users better arrange their time and use electronic devices more efficiently.

[0102] The charging chip (i.e., charging IC (Integrated Circuit)) is responsible for managing the charging process of the battery. There are generally multiple charging chips, such as 3. The charging chip has a charging conversion efficiency. During the charging process, especially the fast charging process, such as in the standby charging scenario, the charging chip is the main source of heat inside the electronic device. For example, at an output current of 10A, the charging efficiency of the charging chip is 96%. If the charging power is 100W, the total heat generated by the charging chip is 4W. In addition, there are resistors in the charging circuit, which will also generate heat. The heat generated by the resistor is proportional to the square of the current I, that is, Q=I 2Rt. At the same time, a battery protection board is also provided inside the electronic device. There are resistors in the circuits related to the battery protection board, which will also generate heat, causing the internal body of the electronic device to heat up during charging, and the internal body temperature rise is too high. If the internal body temperature of the electronic device is too high, it will not only affect the safety performance of the battery. In order to improve the safety performance of the battery and the battery charging rate, and enhance the user's charging experience, the charging power of the battery will be limited according to the heating of the internal body of the electronic device during the charging process, which will further affect the charging speed of the battery. In the scenario of charging while playing, components such as Soc will also generate corresponding heat when working, especially under heavy load (such as large-scale games), components such as Soc will generate a lot of heat, resulting in excessive temperature rise of the internal body of the electronic device, and the problem of current limiting and affecting the charging speed will be more prominent due to the excessive temperature rise of the internal body of the electronic device. Typically, many users will feel that the charging speed of their mobile phones is very slow or even power off when they are charging while playing games, which seriously affects the user's charging experience.

[0103] In order to ensure the safety of the battery during the charging process, increase the charging speed of the battery, and enhance the user's charging experience, an embodiment of the present application provides a transfer cable component. As an external power boosting transfer cable, the transfer cable component expands the charging chip compared to the ordinary charging cable to carry the charging power during the battery charging process of the electronic device. Therefore, when the same charging power is achieved, a part of the heat generated by the charging chip during the charging process can be placed outside the electronic device, thereby reducing the heating of the internal body of the electronic device. In addition, by adjusting the length of different types of power lines in the charging cable and adjusting the impedance of different types of power lines, the current flowing through different types of power lines in the charging cable can be adjusted, thereby ensuring the temperature rise of the transfer cable component, improving the safety performance during the charging process, and enhancing the user's charging experience. When the same temperature rise is achieved, the current inside the electronic device can be retained as a large current for a longer time, thereby improving the charging speed. Furthermore, in the scenario of charging while playing, the charging strategy is controlled by the external charging chip in the adapter cable component, which can decouple the charging heat in the heavy load scenario from the discharge heat of the whole machine, so that the charging heat and the discharge heat of the whole machine do not affect each other, which can not only ensure the performance of the whole machine, but also ensure that the charging current is not limited by the thermal state of the whole machine.

[0104] The present application embodiment provides a switching cable component, see Figure 1 The adapter cable component includes an adapter cable interface, a first charging cable, a charging circuit, a charging plug, etc.

[0105] Among them, the first charging cable is connected to the adapter cable interface, the charging circuit and the charging plug.

[0106] The charging plug is inserted into the charging interface of the electronic device and is used to connect the electronic device and the adapter cable component.

[0107] The charging circuit includes an external charging chip, which is used to manage the charging of the battery of the electronic device. In the embodiment of the present application, a charging chip inside the electronic device and a charging chip in the adapter cable component are provided. To facilitate the distinction between different charging chips, the embodiment of the present application refers to the charging chip inside the electronic device as an internal charging chip, and the charging chip in the adapter cable component as an external charging chip. In addition to the external charging chip, the charging circuit may also include peripheral circuits, etc. The embodiment of the present application does not make specific limitations on the charging circuit. The alignment type of the charging chip may be a charge pump, staggered cascade, series-parallel architecture, etc., as long as the high-power charging function can be achieved. The architecture type of the charging chip may be the same as or different from the charging chip in the side charging circuit.

[0108] The adapter cable interface is used to connect the adapter cable component and the charger. The adapter cable interface can be a USB-A interface socket, or a Type-C interface socket, etc., which is not specifically limited in the present embodiment of the application.

[0109] In the embodiment of the present application, the adapter cable component has two forms, see Figure 1 In one form, the adapter cable interface can be set inside the charging circuit. In this case, the first charging cable has only one section, and the charging plug and the charging circuit are set at both ends of the first charging cable. The first charging cable connects the charging plug and the charging circuit, thereby realizing the connection function with the electronic device and the charger.

[0110] See also Figure 2 In another form, the adapter cable interface can be set outside the charging circuit. In this case, the first charging cable includes two sections, a first section connecting the charging plug and the charging circuit, and a second section connecting the charging circuit and the adapter cable interface. The charging plug and the charging circuit are located at both ends of the first section of the first charging cable, and the charging circuit and the adapter cable interface are located at both ends of the second end.

[0111] In the embodiment of the present application, a BAT power line and a Vbus power line are provided in the cable section of the charging cable for connecting the charging circuit and the charging plug. Figure 1 For the adapter cable components shown in FIG. 1 , the entire section of the first charging cable includes a BAT power line and a Vbus power line. Figure 2For the adapter cable component shown, the first section of the first charging cable includes a BAT power line and a Vbus power line. There are resistors in the BAT power line and the Vbus power line, and both can be equivalent to an impedance. Usually, the equivalent impedance of the BAT power line is not greater than 100mΩ. By adjusting the length of the BAT power line and the Vbus power line, the power flowing through the BAT power line and the Vbus power line can be adjusted to control the temperature of the charging circuit. Specifically, the longer the length of the BAT power supply, the smaller the current flowing through the BAT power line, and the smaller the temperature rise of the charging circuit; the shorter the length of the BAT power line, the larger the current flowing through the BAT power line, and the larger the temperature rise of the charging circuit. Conversely, the longer the length of the Vbus power line, the larger the current flowing through the Vbus power line, and the larger the temperature rise of the charging circuit; the shorter the length of the Vbus power line, the smaller the current flowing through the Vbus power line, and the smaller the temperature rise of the charging circuit.

[0112] Figure 3 and Figure 4 A schematic diagram showing the equivalent impedance of two forms of transition cable components, see Figure 3 and Figure 4 , R7 is the equivalent impedance of the BAT power line, and R8 is the equivalent impedance of the Vbus power line. Figure 3 and Figure 4 The length of the BAT power line and the Vbus power line can be adjusted to adjust the impedance values ​​of R7 and R8, thereby adjusting the current flowing through the BAT power line and the Vbus power line to achieve the purpose of evenly distributing the link loss on the cable and controlling the temperature rise of the charging circuit.

[0113] Furthermore, during the charging process, the various heat-generating components inside the electronic device can be collectively equivalent to an impedance, and the different types of power lines in the charging cable can be collectively equivalent to an impedance. By adjusting the lengths of the different power lines inside the charging cable, the impedance ratio between the inside and outside of the electronic device during the charging process can be adjusted, thereby adjusting the power ratio of the adapter cable component and the electronic device, thereby breaking through the heat generation of the whole machine and the limitations of the charging chip, and achieving the purpose of increasing the charging power of the whole machine. For example, the original charging chip of the electronic device can provide a charging power of 120W, and the electronic device body carries a heat dissipation capacity of 100W, that is, the actual charging power of the electronic device is 100W. When the temperature rise of the whole machine reaches 40°C, the charging speed of the battery will be limited. By adopting the method implemented in this application, the adapter cable component can carry part of the charging power, thereby increasing the charging power of the battery, such as increasing the charging power of 100W to 150W.

[0114] Optionally, in another embodiment of the application, the external circuit of the adapter cable component includes not only a charging circuit, but also an anti-counterfeiting chip. The anti-counterfeiting chip may be an EEPROM (Electrically Erasable Programmable Read Only Memory) type device, or an Emark chip in the PD (Power Delivery) and UFCS (Universal Fast Charging Specification) charging protocol system. The anti-counterfeiting chip includes anti-counterfeiting information, electrical characteristics of the adapter cable component, maximum current supported and other parameters. The anti-counterfeiting chip can identify the adapter cable part, specifically for identifying whether the adapter cable component supports an external charging chip, and when the adapter cable component supports an external charging chip, instruct the electronic device to use the external charging chip of the adapter cable component to charge the battery; the anti-counterfeiting chip can also provide parameters of cable charging performance. If a charging protocol such as PD or UFCS is adopted, the identification of the adapter cable component and the acquisition of anti-counterfeiting information can be obtained by reading the Emark chip in the adapter cable component. When the anti-counterfeiting information is read successfully, it can be determined that the adapter cable component supports the external charging chip, and then the charging configuration parameters supporting the external charging chip are configured. Fig. 9 The charging channel of the middle switch 1 is used to charge the battery simultaneously through the internal and external charging chips of the electronic device.

[0115] In another embodiment of the present application, in order to realize externalization of the charging circuit and convert the voltage and current required for the battery charging process outside the electronic device instead of inside the electronic device, the current Type-C interface needs to be redefined. Figure 5 The existing female socket side, that is, the Type-C protocol on the electronic device side, is shown. Figure 6 The existing plug side, that is, the Type-C protocol on the connecting cable side is shown. Figure 7 The Type-C protocol on the female side is redefined for this application. Figure 8 The plug-side Type-C protocol redefined in this application is shown. Figure 5 and Figure 7 , Figure 6 and Figure 8 It can be seen that this application redefines the TX1+ pin, TX1- pin, RX1+ pin, RX1- pin, TX2+ pin, TX2- pin, RX2+ pin, RX2- pin and SBU pin without designated function (including SBU1 pin and SBU2 pin) in the standard Type-C protocol.

[0116] See also Figure 7The Type-C protocol on the female socket side redefined in the embodiment of the present application is to redefine the TX1+ pin, RX1+ pin, TX2+ pin, and RX2+ pin in the standard Type-C protocol on the female socket side as the connection pins for the output of the external charging chip and the battery input. In the embodiment of the present application, the connection pin can be called the BAT pin; the TX1- pin, RX1- pin, TX2- pin, and RX2- pin in the standard Type-C protocol on the female socket side are redefined as TX1- pin, RX1- pin, TX2- pin, and RX2- pin are redefined as the transmission of communication signals between the electronic device and the external charging chip. If the I2C protocol is used, the TX1-pin, RX1-pin, TX2-pin and RX2-pin can be redefined as the SDA pin and SCL pin of the I2C interface. In the application embodiment, the TX1-pin and TX2-pin can be called the SCL pin, and the RX1-pin and RX2-pin can be called the SDA pin; the SUB1 pin and SUB2 pin in the standard female socket side Type-C protocol are redefined as the pins for transmitting interrupt signals between the electronic device (specifically, Soc) and the external charging chip. In the embodiment of the present application, the pin can be called the INT pin. It should be noted that this definition can only be used as an example of implementation. The redefinition of the signal channel can be adjusted according to the actual power requirements and routing requirements. For example, RX2+ and TX2+ can also be used as the path pins for battery charging, and TX1- and RX1+ can also be used as the path pins for I2C. Here, only one feasible arrangement is described. In addition, the arrangement order of TX1+ pin, TX1- pin, RX1+ pin, RX1- pin, TX2+ pin, TX2- pin, RX2+ pin, RX2- pin, SBU1 pin and SBU2 pin can be the same as the arrangement order of the standard female socket side Type-C protocol, or can be adjusted randomly.

[0117] See also Figure 8The plug-side Type-C protocol redefined in the embodiment of the present application is to redefine the TX1+ pin, RX1+ pin, TX2+ pin, and RX2+ pin in the standard plug-side Type-C protocol as the connection pins between the output of the external charging chip and the battery input. In the embodiment of the present application, the connection pin can be called the Vbat pin; the TX1- pin, RX1- pin, TX2- pin, and RX2- pin in the standard plug-side Type-C protocol are redefined as pins for transmitting communication signals between the electronic device and the external charging chip. If the I2C protocol is adopted, the TX1- pin, RX1- pin, TX2- pin, and RX2- pin can be redefined as the SDA pin and SCL pin of the I2C interface. In the embodiment of the application, the TX2- pin can be called the SCL pin, and the RX2- pin can be called the SDA pin; the SUB1 pin and SUB2 pin in the standard plug-side Type-C protocol are redefined as pins for transmitting interrupt signals between the electronic device (specifically, Soc) and the external charging chip. In fact, the redefined Type-C protocol on the plug side corresponds to the redefined Type-C protocol on the socket side. The difference is that there is no need to consider the definition of forward and reverse insertion.

[0118] The charging plug included in the adapter cable component of the embodiment of the present application supports the redefined plug-side Type-C protocol, and the charging interface of the electronic device supports the redefined socket-side Type-C protocol. When the charging plug is inserted into the charging interface of the electronic device, the voltage and current required for the battery charging process can be converted outside the electronic device.

[0119] In addition, considering that the fast charging charger does not need to support USB data communication function, in the fast charging scenario, the USB3.x function is not needed, and the USB2.0 channel can be used as the communication channel for some charging communication protocols. Therefore, there is no need to change the adapter cable interface and the cable components it is inserted into, as well as the protocols supported by the charger.

[0120] Based on the redefined Type-C protocol on the female side, Fig. 9 A block diagram showing the circuit connections on the electronic device side is shown in FIG. Fig. 9, the Vbat of the A11 pin (i.e., BAT pin, corresponding to the RX2+ pin in the standard Type-C protocol on the female socket side), the B2 pin (i.e., BAT pin, corresponding to the TX2+ pin in the standard Type-C protocol on the female socket side), the A2 pin (i.e., BAT pin, corresponding to the RX1+ pin in the standard Type-C protocol on the female socket side), and the B11 pin (i.e., BAT pin, corresponding to the RX1+ pin in the standard Type-C protocol on the female socket side) in the battery interface of the electronic device are connected to the positive electrode of the battery through switch 1 as a charging channel, wherein switch 1 can control the opening of the charging channel of the external charging chip after identifying that the transfer cable component supports the function of the external charging chip. If the connected transfer cable component does not support the charging function using the external charging chip, switch 1 can be disconnected, and at this time, there is no effect on the connection of the transfer cable component to other cable components, charging devices, and electronic devices. The A10 pin (i.e., SCL pin, corresponding to the RX2- pin in the standard Type-C protocol on the female side), the B3 pin (i.e., SDA pin, corresponding to the TX2- in the standard Type-C protocol on the female side), the A3 pin (i.e., SDA pin, corresponding to the TX1- in the standard Type-C protocol on the female side) and the B10 pin (i.e., SCL pin, corresponding to the RX1- in the standard Type-C protocol on the female side) in the battery interface of the electronic device can be channels supporting the I2C protocol, and the A3 pin and the B3 pin can be connected together through SDA, and the A10 pin and the B10 pin can be connected together through SCL. The A3 pin and the B3 pin are connected to the I2C channel of the Soc through switch 2 to realize the communication function. The A10 pin and the B10 pin are connected to the I2C channel of the Soc through switch 3 to realize the communication function. In the fast charging scenario, the D+ pin and the D- pin can be used as the communication channel of the fast charging protocol. The CC pin can be used as the communication channel of the PD fast charging protocol. The functions of CC1 and CC2 are the same as those defined by the Type-C protocol on the female side of the original standard, including detection of insertion, identification of forward and reverse insertion, communication based on the PD protocol, and setting Vconn to VPA (VCONN Powered Accessory) and VPD (VCONN Powered USB Device) for power supply, etc. Fig. 9 R2 and R3 in the charger are used for forward and reverse plug identification. The charger power supply capacity identification function complies with the TYPE-C protocol. Fig. 9 In It means that each component in the charging circuit is effective only when the input signal is at a low level. Fig. 9 The whole charging circuit shown usually includes a fast charging chip and a buck charger, etc.

[0121] Based on the redefined plug-side Type-C protocol, Fig.10 A block diagram showing the circuit connections on the adapter side. Fig.10 , the Vbat of the charging plug A2 pin (i.e., Vbat pin, corresponding to the RX1+ pin in the standard plug side Type-C protocol), A11 pin (i.e., Vbat pin, corresponding to the TX2+ pin in the standard plug side Type-C protocol), B2 pin (i.e., Vbat pin, corresponding to the RX2+ pin in the standard plug side Type-C protocol), and B11 pin (i.e., Vbat pin, corresponding to the TX1+ pin in the standard plug side Type-C protocol) is connected to the Vbat power line of the charging circuit, and the Vbus of the A4 pin (i.e., Vbus pin, corresponding to the Vbus pin in the standard plug side Type-C protocol), A9 pin (i.e., Vbus pin, corresponding to the Vbus pin in the standard plug side Type-C protocol), B4 pin (i.e., Vbus pin, corresponding to the Vbus pin in the standard plug side Type-C protocol), and B9 pin (i.e., Vbus pin, corresponding to the Vbus pin in the standard plug side Type-C protocol) is connected to the Vbus power line of the charging circuit.

[0122] See also Fig.11 The present application embodiment provides a charging system, which includes an electronic device, a transfer cable component, a connecting cable component, and a charger. Figure 1 The adapter cable component shown in the figure includes a first cable charger plug, a second charging cable and a second cable charger plug, etc. The first cable charger plug and the second cable charger plug are arranged at both ends of the second charging cable. Figure 2 The structure of the charging system can be found in the adapter cable components shown in Fig.12 .

[0123] In an embodiment of the present application, when the charging plug of the adapter cable component is inserted into the charging interface of the electronic device, the first cable charger plug of the connecting cable component is inserted into the adapter cable interface of the adapter cable component, and the second cable charger plug of the connecting cable component is inserted into the charging interface of the charger, the charger converts the AC power into the voltage and current required for charging, thereby charging the battery of the electronic device.

[0124] In an embodiment of the present application, the charging interface of the electronic device supports the redefined Type-C protocol on the female socket side, and can convert the voltage and current required for the battery charging process outside the electronic device.

[0125] Fig.13 The system architecture diagram of this application is shown in FIG. Fig.13The electronic device includes a battery (i.e., a cell), a charging circuit, a charging interface, a battery protection board, etc. The battery protection board can be located between the battery (i.e., a cell) and the charging circuit. The charging circuit can include multiple charging chips, a system on a chip (Soc), and a PMU, etc. The battery can input power through the charging interface and be charged through the charging circuit. By adopting Fig.11 or Fig.12 The charging system shown can charge the battery of the electronic device.

[0126] In order to better average the output current of each charging chip (including the charging chip inside the electronic device and the external charging chip in the adapter cable component), improve the charging efficiency, and disperse the heat of the electronic device, such as Fig.14 As shown, the battery protection board can also be inverted, that is, the battery protection board is placed between the battery (ie, the battery cell) and the charging port.

[0127] Fig.15 This is a schematic diagram of the charging circuit inside the electronic device, see Fig.15, the internal charging circuit includes the charging path of the main charger (battery) and the SC chip (i.e., the charging chip). Among them, the main charger supports non-fast charging mode and fast charging mode, and the charging methods of the main charger include trickle charging mode, pre-charging mode, constant current charging mode, and constant voltage charging mode. The SC chip includes SC1 and SC2, etc. SC1 and SC2 include fast charging charging chips that support fast charging and their peripheral circuits, which are used to provide fast charging paths with higher power and efficiency than the main charger. The SC chip described here is only an example of a fast charging chip. A charge pump architecture can be adopted, for example, the input voltage is 4 times the output voltage, becoming a 4:1 charging chip, or an existing charging chip architecture in the industry, such as an interlaced cascade and series-parallel architecture, etc. The embodiment of the present application does not limit this, and can achieve the fast charging function. When the charger is inserted, the adapter cable component can be identified by the signal line CC1 and the signal line CC2. In the Type-C protocol, the signal line CC1 and the signal line CC2 are defined as: a signal line that is directly connected from the adapter cable charging plug to the adapter cable USB socket and transparently transmitted to the charging cable. After the cable is connected to the electronic device, the terminating resistor on the CC line of the charging cable forms a voltage divider with R2 and R3. For example, R2 and R3 are both 5.1K. R2 and R3 usually exist inside the chip. The figure only shows them as an illustrative example. The identification of the adapter cable component can also directly adopt the method of reading the cable information supported by the communication protocol (PD fast charging protocol, UFCS protocol, etc.) from the anti-counterfeiting chip (such as Emark chip). When the adapter cable component is identified as a fast charging cable, it can interact through the fast charging protocol, or it can interact with the fast charging protocol first to determine the fast charging protocol supported by the charger and the electronic device, and then check whether the adapter cable component is a fast charging cable. The purpose of this operation is to determine that the cable connected to the electronic device is a fast charging cable, USB SS is not supported, and the charger is a fast charging charger. In the interaction of the charging protocol, the charging protocol that supports SCP successfully interacts with the charger through D+ and D-, and after the adapter cable component is determined to be a fast charging cable, the SBU can be switched to the I2C channel. At this time, the anti-counterfeiting information in the anti-counterfeiting chip of the adapter cable component can be read through I2C. When the anti-counterfeiting information is read successfully, it can be determined that the adapter cable component is a fast charging cable that supports an external charging chip, and then the charging parameters that support the external charging chip are configured. After the charging parameters are configured, the charging can be turned on. Fig. 9 Switch 1 in the device can be used to charge the battery simultaneously through the internal charging chip of the electronic device and the external charging core in the adapter cable component.

[0131] See Table 1, under the conditions of 100W and 35W, the heat consumption of the mainboard side of the present application solution and the existing solution is compared. Under the power of 100W, the heat loss of the mainboard of the present application is 66.23% of that of the existing solution, and under the power of 35W, the heat consumption of the mainboard of the present application is 71.13% of that of the existing solution. The heat consumption of the solution of the present application is significantly reduced, and the temperature rise of the whole machine can be effectively reduced under the same whole machine heat dissipation environment, thereby improving the fast charging experience.

[0135] See Table 2, the impedance of the cable BAT power line is 25mΩ. When the power is 100W and 35W respectively, the heat loss of the circuit board of the solution of this application and the existing solution can be compared. It can be seen that at 100W power, the heat loss of the circuit board of this application is 54.70% of the existing solution, and at 35W power, the heat loss of the mainboard of the solution of this application is 74.71% of the existing solution. The heat loss is significantly reduced. Under the same whole machine heat dissipation environment, the heat loss of the cable charging circuit board can be effectively reduced, so that the cable has no hot spots and meets the temperature specifications, thereby improving the fast charging experience.

[0136] The present application embodiment provides a charging method, which applies Fig.11 or Fig.12 The charging system shown is shown in Fig.16 , the method flow provided in the embodiment of the present application includes:

[0137] 1601. When detecting connection with a charger, the electronic device determines whether the adapter cable component meets fast charging conditions.

[0138] Specifically, the electronic device determines whether the adapter cable component meets the fast charging condition, including the following steps:

[0139] 16011. The electronic device determines whether the adapter cable component is a proprietary fast charging cable component.

[0140] Among them, proprietary fast-charging cable components refer to fast-charging cable components developed by a certain manufacturer or company for electronic devices. When the adapter cable component is inserted into the charging port of the electronic device and the connecting cable component is inserted into the charger, the electronic device can obtain the cable identification of the adapter cable component and identify whether the adapter cable component is a proprietary fast-charging cable component through the cable identification.

[0141] 16012. When the adapter cable component is a proprietary fast charging cable component, the electronic device determines whether the adapter cable component supports a preset fast charging protocol.

[0142] Among them, the fast charging protocol can be SCP (Super Charge Protocol), UFCS, PD, QC (Quick Charge) protocol, etc. The embodiment of the present application does not make specific limitations on the fast charging protocol.

[0143] 16013. When the adapter cable component supports the preset fast charging protocol, the electronic device determines whether the adapter cable component supports the external charging chip based on the anti-counterfeiting chip.

[0144] When the adapter cable component supports the preset fast charging protocol, in order to realize the communication between the electronic device and the external charging chip, the electronic device needs to open the communication channel with the external charging chip in the subsequent steps. For example, when the adapter cable component supports the I2C protocol, the electronic device needs to switch the SBU channel to the I2C channel to realize the communication between the electronic device and the external charging chip. When the communication channel with the external charging chip is opened, the electronic device can read the anti-counterfeiting information from the anti-counterfeiting chip of the adapter cable component. If the anti-counterfeiting information can be successfully read, it can be determined that the adapter cable component supports the external charging chip.

[0145] 16014. When the adapter cable component supports an external charging chip, the electronic device determines whether the adapter cable component is a cable component that matches the charger.

[0146] When the electronic device determines whether the adapter cable component is a cable component that matches the charger, it can obtain the charging parameters of the charger and the charging parameters supported by the adapter cable component. If the parameters of the two match, the adapter cable component is determined to be a cable component that matches the charger. For example, if the maximum charging current of the charger is 5A and the maximum charging current supported by the adapter cable component is also 5A, the adapter cable component is determined to be a cable component that matches the charger.

[0147] 16015 When the adapter cable component is a cable component that matches the charger, the electronic device determines that the adapter cable component meets the fast charging conditions.

[0148] 1602. When the adapter cable component meets the fast charging conditions, the electronic device configures the first charging parameters.

[0149] The first charging parameter may be a charging parameter that supports charging with an external charging chip.

[0150] 1603. Based on the first charging parameter, the electronic device uses an external charging chip to charge the battery.

[0151] Based on the first charging parameter, the electronic device may open a communication channel with the external charging chip, and in response to the opening of the communication channel with the external charging chip, the external charging chip may be used to charge the battery of the electronic device.

[0152] 1604. When the adapter cable component does not meet the fast charging conditions, the electronic device configures the second charging parameters.

[0153] The second charging parameter is a charging parameter that does not support charging with an external charging chip.

[0154] Specifically, it is determined that the adapter cable components do not meet the fast charging conditions, including but not limited to the following situations:

[0155] In the first case, when the adapter cable component is not a dedicated fast charging cable component, the electronic device determines that the adapter cable component does not meet the fast charging conditions.

[0156] In the second case, when the adapter cable component does not support the preset fast charging protocol, the electronic device determines that the adapter cable component does not meet the fast charging conditions.

[0157] In the third case, when the adapter cable component does not support the external charging chip, the electronic device determines that the adapter cable component does not meet the fast charging conditions.

[0158] In the fourth case, when the adapter cable component is not a cable component that matches the charger, the electronic device determines that the adapter cable component does not meet the fast charging conditions.

[0159] 1605. Based on the second charging parameter, the electronic device does not use an external charging chip to charge the battery.

[0160] Based on the second charging parameter, the electronic device uses an internal charging chip instead of an external charging chip to charge the battery.

[0161] Fig.17 A flowchart of the charging method provided in the embodiment of the present application is shown. Fig.17When it is detected that a charger is inserted, the electronic device determines whether the adapter cable component is a dedicated fast charging cable. When the adapter cable component is not a dedicated fast charging cable, non-fast charging parameters (i.e., the second charging parameters) can be configured, and then the internal charging chip is used to charge the battery of the electronic device; when the adapter cable component is a dedicated fast charging cable, it can be determined whether the adapter cable component supports the fast charging protocol. If the adapter cable component does not support the fast charging protocol, non-fast charging parameters (i.e., the second charging parameters) are configured, and then the internal charging chip is used to charge the battery of the electronic device; if the adapter cable component supports the fast charging protocol It is proposed that the socket interface can be switched to the I2C channel, and then the anti-counterfeiting information can be read from the anti-counterfeiting chip. If the anti-counterfeiting information is read from the anti-counterfeiting chip, it is determined whether the adapter cable component is the target cable, that is, the fast charging cable that matches the charger. If the adapter cable component is not the target cable, the non-fast charging parameters (that is, the second charging parameters) are configured, and then the internal charging chip is used to charge the battery of the electronic device; if the adapter cable component is the target cable, the fast charging parameters (that is, the first charging parameters) are configured, and then the internal charging chip and the external charging chip are used to charge the battery of the electronic device.

[0162] The adapter cable component provided in the embodiment of the present application can be used as a fast charging cable, using an external charging chip to charge the battery, and can also be used as an ordinary cable to connect an electronic device and a charger. By judging the adapter cable component, an external charging chip can be used to charge the battery when the adapter cable component meets the fast charging conditions, thereby providing a variety of charging methods.

[0163] The present application embodiment provides a charging strategy determination method, which is applied to Fig.11 or Fig.12 The charging system shown is shown in Fig.18 , the method flow provided in the embodiment of the present application includes:

[0164] 1801. During charging of a battery of an electronic device, the electronic device determines a maximum charging current of the battery based on at least one of a battery temperature and a body temperature.

[0165] During the process of charging the battery of an electronic device, the user can use the electronic device while charging. To improve the charging safety and speed, the electronic device can obtain the battery temperature of the electronic device, or the battery temperature and the body temperature, and then determine the maximum charging current of the electronic device based on the battery temperature, or based on the battery temperature and the body temperature.

[0166] Specifically, the electronic device determines the maximum charging current of the battery based on at least one of the battery temperature and the body temperature, and may adopt the following method:

[0167] 18011. The electronic device determines whether the battery temperature is greater than a first preset temperature.

[0168] The first preset temperature may be set by a technician, and the first preset temperature may be expressed as Tb.

[0169] 18012. When the battery temperature is greater than a first preset temperature, the electronic device determines that the maximum charging current is a first current.

[0170] The maximum charging current can be expressed as It, and the first current can be expressed as Ir.

[0171] 18013. When the battery temperature is lower than the first preset temperature, the electronic device determines whether the body temperature is higher than the second preset temperature.

[0172] The second preset temperature can be set by a technician, the second preset temperature is lower than the first preset temperature, and the second preset temperature can be expressed as T1.

[0173] 18014. When the body temperature is lower than a second preset temperature, the electronic device determines that the maximum charging current is the second current.

[0174] The second current can be expressed as I1, and the second current is smaller than the first current.

[0175] 18015. When the body temperature is greater than the second preset temperature, the electronic device determines whether the body temperature is greater than the third preset temperature.

[0176] The third preset temperature may be set by a technician, the third preset temperature is greater than the second preset temperature, and the third preset temperature may be expressed as T2.

[0177] 18016. When the body temperature is lower than a third preset temperature, the electronic device determines that the maximum charging current is a third current.

[0178] The third current can be expressed as I2, and the third current is greater than the second current and less than the first current.

[0179] 18017. When the body temperature is greater than the third preset temperature, the electronic device determines whether the body temperature is greater than a fourth preset temperature.

[0180] The fourth preset temperature may be set by a technician, the fourth preset temperature is greater than the third preset temperature, and the fourth preset temperature may be expressed as T3.

[0181] 18018. When the body temperature is lower than a fourth preset temperature, the electronic device determines that the maximum charging current is a fourth current.

[0182] The fourth current can be expressed as I3, and the fourth current is greater than the third current.

[0183] 18019. When the body temperature is greater than the fourth preset temperature, the electronic device determines that the maximum charging current is the fifth current.

[0184] The fifth current can be expressed as I4. The first preset temperature, the second preset temperature, the third preset temperature and the fourth preset temperature are, in descending order: the first preset temperature, the fourth preset temperature, the third preset temperature, the second preset temperature; the first current, the second current, the third current, the fourth current and the fifth current are, in descending order: the first current, the fifth current, the fourth current, the third current, the second current.

[0185] 1802. Based on the maximum charging current and the reference maximum current, the electronic device determines a current charging current of the battery.

[0186] In the embodiment of the present application, when determining the current charging current based on the maximum charging current and the reference maximum current, the minimum current between the maximum charging current and the reference maximum current can be obtained, and then the minimum current is used as the current charging current. The reference maximum current is determined according to the maximum current at the current voltage required by the temperature-controlled maximum current and the battery charging curve. The current charging current can be expressed as Ib.

[0187] 1803. Based on the current charging current, the electronic device determines a charging strategy for the battery.

[0188] Specifically, based on the current charging current, the electronic device determines the charging strategy of the battery, which may include the following steps:

[0189] 18031. The current charging current is greater than a first current threshold, and the electronic device determines that the charging strategy of the battery is the first strategy.

[0190] Among them, the first current threshold can be set by a technician, and the first current threshold can be expressed as Is1. The first strategy is to use all the internal charging chips and external charging chips of the electronic device to charge the battery. Assuming that the electronic device includes three charging chips, of which there are two internal charging chips and one external charging chip, the first strategy is to use two internal charging chips and one external charging chip to charge the battery of the electronic device at the same time.

[0191] 18032. The current charging current is less than the first current threshold but greater than the second current threshold, and the electronic device determines that the charging strategy of the battery is the second strategy.

[0192] The second current threshold can be set by a technician, and the second current threshold can be expressed as Is2. The second strategy is to use the internal charging chip and the external charging chip of the electronic device to charge the battery. Assuming that the electronic device includes three charging chips, of which there are two internal charging chips and one external charging chip, the second strategy is to use one internal charging chip and one external charging chip to charge the battery of the electronic device at the same time.

[0193] 18033. The current charging current is less than the second current threshold, and the electronic device determines that the charging strategy of the battery is the third strategy.

[0194] The third strategy is to use an external charging chip of the electronic device to charge the battery. Assuming that the electronic device includes three charging chips, including two internal charging chips and one external charging chip, the second strategy is to use only one external charging chip to charge the battery of the electronic device.

[0195] Fig.19 The flowchart of the charging strategy determination method provided by the embodiment of the present application is shown, assuming that the electronic device has two internal charging chips (i.e., the charging IC on the motherboard) and an external charging chip (i.e., the external charging IC) on the adapter cable component. Fig.19In the process of charging the battery of the electronic device, the battery temperature of the electronic device can be obtained to determine whether the battery temperature of the electronic device is greater than a first preset temperature Tb. If the battery temperature of the electronic device is greater than the first preset temperature Tb, the maximum charging current It is set to the first current Ir; if the battery temperature of the electronic device is less than the first preset temperature Tb, the body temperature (i.e., the temperature of the entire housing) is obtained to determine whether the body temperature is greater than a second preset temperature T1. If the body temperature is less than the second preset temperature T1, the maximum charging current It is set to the second current I1; if the body temperature is greater than the second preset temperature T1, it is determined whether the body temperature is greater than a third preset temperature T2. If the body temperature is less than the third preset temperature T2, the maximum charging current It is set to the third current I2; if the body temperature is greater than the third preset temperature T2, it is determined whether the body temperature is greater than a fourth preset temperature T3. If the body temperature is less than the fourth preset temperature T3, the maximum charging current It is set to the fourth current I3; if the body temperature is greater than the fourth preset temperature T3, the maximum charging current It is set to the fifth current I4. After determining the maximum charging current It, the electronic device obtains the reference maximum current, and then obtains the minimum value of the maximum charging current It and the reference maximum current as the current charging current Ib. Next, the electronic device determines whether the current charging current Ib is greater than the first current threshold Is1. If the current charging current Ib is greater than the first current threshold Is1, the two charging ICs on the mainboard and the external charging IC are used to charge the battery at the same time; if the current charging current Ib is less than the first current threshold Is1, it is determined whether the current charging current Ib is greater than the second current threshold Is2. If the current charging current Ib is greater than the second current threshold Is2, one charging IC on the mainboard and the external charging IC are used to charge the battery at the same time; if the current charging current Ib is less than the second current threshold Is2, the external charging IC is used to charge the battery at the same time.

[0196] This application introduces an external charging chip and flexibly adjusts the charging strategy according to the battery temperature and the body temperature. Different charging chips are used to charge the battery at different battery temperatures and body temperatures. This not only completely externalizes the charging heat to achieve thermal balance, but also ensures that the body performance is not affected by the charging heat, thereby improving the user's charging experience. Especially in the scenario of playing while charging, the battery charging and discharging temperature rise are completely decoupled, which not only ensures the user's entertainment experience, but also allows the battery to be charged quickly.

[0197] An embodiment of the present application provides a computer-readable storage medium, wherein at least one computer program is stored in the computer-readable storage medium.
