It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0015] Referring to Figures 1, 2 and 3, the present application provides a technical solution: a data line, comprising an input controller, an output controller and a connecting line, the input controller and the output controller being connected through the connecting line;

[0016] The input controller comprises an input interface and an input chip module, the input interface being used for connecting a power adapter, and the input chip module being used for obtaining a target output power supported by the power adapter.

[0017] The output controller comprises an output interface and an output chip module, the output interface being used for connecting a device to be charged, and the output chip module being used for obtaining a target input power supported by the device to be charged, and determining an actual charging power of the device to be charged when the device to be charged is being charged according to the target input power and the target output power.

[0018] Specifically, as shown in Figure 1, the data line is a data line supporting a charging function. The data line is composed of an input controller, an output controller and a connecting line, wherein:

[0019] The input controller refers to the part of the data line connected to the power adapter at one end, i.e. the input end protocol module, which is responsible for identifying and executing the communication protocol between the power adapter and the input end protocol module, and can control the conduction state of the line between the power adapter and the input end protocol module. In addition, the input end protocol module can also obtain the maximum output power that the power adapter can support.

[0020] The input controller is composed of an input interface and an input chip module. The input interface refers to the part in the input end protocol module for accessing the power adapter. Understandably, it can be a physical socket or a wireless connection method such as Bluetooth, Wi-Fi, etc. The function of the input interface is to provide a stable connection point, so that the power adapter can supply power to the input controller, and allow communication between the two. The input chip module is composed of multiple chips, which work together to obtain the target output power supported by the power adapter.

[0021] The output controller refers to the part of the output end protocol module connected to the device to be charged on the data line, which is responsible for identifying and executing the communication protocol with the device to be charged, and can control the conduction state of the line between the device to be charged and the output controller. In addition, the output controller can also obtain the target input power required by the device to be charged.

[0022] The output controller is composed of an output interface and an output chip module. The output interface refers to the part in the output controller for accessing the device to be charged. It can be a physical socket or a wireless connection method such as Bluetooth, Wi-Fi, etc. The function of the interface is to provide a stable connection point, so that the device to be charged can receive the power supply provided by the output controller, and allow communication between the two. The output chip module is composed of multiple chips, which work together to obtain the target input power supported by the device to be charged, and determine the actual charging power of the device to be charged when charging according to the target input power and the target output power.

[0023] The connection line refers to the physical connection part between the input end protocol module and the output end protocol module, which can be a transmission medium such as a wire or an optical fiber, used to transmit power or signals generated by the power adapter to the device to be charged.

[0024] Optionally, the input chip module includes an input control chip and an input power management chip, the input control chip is used to obtain the target output power supported by the power adapter; the input power management chip is used to turn on the power transmission line between the input controller and the output controller according to the actual charging power.

[0025] Specifically, as shown in FIG. 3, the multiple chips in the input chip module include at least an input control chip and an input power management chip. Among them:

[0026] The input control chip refers to the part in the input controller that manages and controls the overall system operation. Understandably, the input control chip may contain one or more microcontrollers, digital signal processors, and other electronic components, which can be set according to actual needs. Its main task is to receive information from external devices (such as power adapters) and make appropriate decisions based on these information. For example, one of the tasks of the input control chip is to obtain the target output power value that the power adapter can support and send this value to the output control chip of the output controller for synchronization. At the same time, the input control chip also needs to monitor the running state of the entire system and adjust the working mode of each component according to the actual situation to ensure that the system is always in the best working state.

[0027] The input power management chip refers to the part in the input controller that manages and controls the power supply. Understandably, the input power management chip may contain one or more power converters, voltage stabilizers, battery chargers, and other electronic components, which can be set according to actual needs. Its main task is to ensure that the system always has sufficient power supply and improves energy utilization efficiency as much as possible. For example, one of the tasks of the input power management chip is to adjust the output voltage and current of the power adapter according to the instructions issued by the input control chip to meet the needs of different loads. At the same time, the input power management chip also needs to monitor the state of the power adapter and take measures to protect the system from overload, short circuit, and other problems when necessary.

[0028] Optionally, the input chip module also includes an input protocol chip, which is used to identify the first charging protocol type supported by the power adapter and to turn on the power transmission line between the input controller and the power adapter according to the first charging protocol type.

[0029] Specifically, the input protocol chip is included in the multiple chips in the input chip module. The input protocol chip can identify the charging protocol type (i.e. the first charging protocol type) used by the power adapter, such as USB PD, QC, etc. Different power adapters may use different charging protocol types, so the input protocol chip needs to have the support capability of multiple charging protocol types to adapt to power adapters of different charging protocol types. The input protocol chip confirms the communication method and parameter settings of both parties by performing handshaking with the power adapter. The handshaking process may involve negotiation of voltage, current, power, etc. to ensure stable and reliable communication between the power adapter and the input controller.

[0030] After protocol recognition and handshaking, the input protocol chip turns on the circuit between the power adapter and the input controller, allowing the power adapter to provide power to the input controller. This operation usually involves functions such as switch control or signal switching to turn the circuit on and off. The input protocol chip also needs to cooperate with the input control chip to transmit the power adapter's power information to the input control chip for subsequent power management. This includes obtaining the target output power that the power adapter can support and sending it to the input control chip for processing.

[0031] For example, once the input protocol chip identifies the charging protocol of the power adapter (i.e., the first charging protocol type), it activates or configures the necessary circuits according to the specifications of this protocol, thereby establishing an effective power transmission channel between the input controller (i.e., the control chip in the input protocol module) and the power adapter. This process may involve dynamic adjustment of voltage and current, execution of a safety handshake protocol to ensure efficient and safe power transmission. In short, the protocol chip acts as a smart "switch" that ensures power transmission meets all requirements of the identified protocol, maximizing compatibility and safety while optimizing charging efficiency.

[0032] Optionally, the output chip module includes an output control chip and an output power management chip. The output control chip is used to obtain the target input power that the device to be charged can support; the output power management chip is used to turn on the power transmission circuit between the input controller and the output controller according to the actual charging power.

[0033] Specifically, as shown in FIG. 3, the multiple chips in the output chip module include at least an output control chip and an output power management chip. Among them:

[0034] The output control chip is an integrated circuit whose main function is to process and control the operation of the output controller. Specifically, the output control chip is responsible for identifying the protocol required by the device to be charged and communicating with the input control chip of the input controller to synchronize the power support on both ends.

[0035] The output power management chip is an integrated circuit whose main function is to manage and control the power supply. In the output manager, the output power management chip is responsible for receiving instructions from the output control chip and controlling the output of the power supply according to these instructions. For example, if the output control chip instructs the output power management chip to output energy according to the demand power of the device to be charged (i.e., the actual charging power), the power management chip will adjust the output voltage and current of the power supply to meet the demand of the powered device.

[0036] Optionally, the output chip module further comprises an output protocol chip, which is configured to identify a second charging protocol type supported by the to-be-charged device, and to turn on a power transmission line between the output controller and the to-be-charged device according to the second charging protocol type.

[0037] Specifically, the output protocol chip can identify the charging protocol (i.e., the second charging protocol type) used by the to-be-charged device, such as USB PD (Power Delivery), Qualcomm Quick Charge, Apple's iPod / iPhone fast charging protocol, etc. Different to-be-charged devices may support different charging protocols, so the output protocol chip needs to have the ability to support multiple protocols to ensure compatibility with various to-be-charged devices.

[0038] After identifying the correct protocol (i.e., the second charging protocol type), the output protocol chip will perform a handshake with the to-be-charged device, which is a communication process to confirm the communication method and parameter settings of both parties. The handshake process may include some security authentication operations to ensure the security and effectiveness of data exchange.

[0039] After completing protocol identification and handshake, the output protocol chip will open the power transmission line between the to-be-charged device and the output controller, allowing power to flow from the output controller to the to-be-charged device. This process may involve switch control or signal switching to ensure smooth power transmission. The output protocol chip may also participate in the power management process, for example, in some cases it may need to limit the output power to protect the device from overload.

[0040] Optionally, the input chip module comprises an input control chip, and the output chip module comprises an output control chip; the input control chip and the output control chip are electrically connected, and the output control chip is configured to obtain a target output power acquired by the input control chip from the power adapter, and to determine an actual charging power of the to-be-charged device when charging according to the target input power and the target output power.

[0041] Specifically, as shown in FIG. 2, the output control chip of the output controller first establishes a communication link with the input control chip of the input controller to exchange necessary information therebetween. After receiving the information of the power adapter, the input control chip of the input controller calculates the target output power that the power adapter can provide. The input control chip of the input controller sends the calculated target output power to the output control chip of the output controller. After receiving the target output power sent by the input control chip of the input controller, the output control chip of the output controller stores the target output power for subsequent use. Similarly, the output control chip of the output controller also acquires the target input power required by the device to be charged and sends the information to the input control chip of the input controller. Finally, the two control chips synchronize the information according to the target output power and the target required power acquired by each of them, so as to ensure that the power transmission of the entire system meets the actual requirements.

[0042] In one embodiment, the input power management chip and the output power management chip can adopt the following models: master IC, master controller integrated circuit (MP5316, ETA6884, SW6103S, SW6208, IP5389, SW6003, SW6206, IP5353, IP5356, IP5320, SW6007, SW6202, SC8910, SW6238, SC8910A, SC8812, SC8905).

[0043] In one embodiment, the input control chip and the output control chip can adopt the following models: MCU, microcontroller (CSU32G10, CS32G020, KS08F102GSD, CMS8S6990, ZX9025, PFS122, ZWS8025).

[0044] In an example, the output control chip is configured to: in a case where the target input power is greater than the target output power, determine the target output power as the actual charging power for charging the device to be charged.

[0045] In an example, the output control chip is configured to: in a case where the target input power is less than the target output power, determine the target input power as the actual charging power for charging the device to be charged.

[0046] In an example, the output control chip is configured to: in a case where the target input power is equal to the target output power, determine the target input power or the target output power as the actual charging power for charging the device to be charged.

[0047] Specifically, during the actual charging process, the output control chip in the output controller determines the actual charging power of the device to be charged according to the known target output power and target input power. Specifically, the following cases are included:

[0048] Case one: the target output power of the input end is greater than the target input power of the output end, and the energy is output according to the target input power of the output end.

[0049] Case two: the target output power of the input end is less than the target input power of the output end, and the output is performed according to the target output power of the input end.

[0050] Case three: the target output power of the input end is equal to the target input power of the output end, at this time, since the powers of the two are the same, the output can be performed according to the target output power and the target input power.

[0051] The purpose of this is to ensure the safety and efficiency of the charging process, and to avoid the occurrence of battery damage or other problems caused by overcharging or undercharging.

[0052] Optionally, the output control chip is configured to: in the case where the target input power is equal to the target output power, determine the target input power or the target output power as the actual charging power of the device to be charged.

[0053] Specifically, the selection of the target input power and the target output power can be set according to actual needs. For example, the target output power is the maximum output power supported by the power adapter, and the target input power is the maximum input power supported by the device to be charged. By setting the target output power to be the maximum output power supported by the power adapter and the target input power to be the maximum input power supported by the device to be charged, the following beneficial effects can be achieved:

[0054] First, through information synchronization, the power transmission during the charging process can be optimized, unnecessary energy waste can be avoided, and the charging efficiency can be improved.

[0055] Second, by limiting the charging current and voltage, overcharging or undercharging problems can be prevented, and the battery can be protected from damage.

[0056] Third, since different devices have different charging power requirements, through information synchronization, the charging power can be adjusted according to the specific requirements of the device, so that this scheme is suitable for various types of electronic devices.

[0057] Fourth, through information synchronization, the circuit design is simplified, the cost and complexity are reduced, and the reliability and stability of the product are improved.
