[0067] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0068] Refer to Figure 1 , which shows a flowchart of steps of a method for adaptively adjusting charging parameters of multiple adapters provided in an embodiment of the present invention, and specifically may include the following steps:

[0069] Step 101, initialize the charging IC and verify the communication function;

[0070] Step 102, detect the real-time charging current of the charging IC in the pre-charging mode and verify the charging working state;

[0071] Step 103, collect the charging current data of the charging IC multiple times, determine the power level of the adapter according to the continuous collection results, and set the adapter power level flag bit;

[0072] Step 104, set a corresponding charging current safety threshold based on the adapter power level, and store the charging current safety threshold as the charging parameter of the current adapter; the charging current safety threshold is lower than the rated current value of the adapter;

[0073] Step 105, switch between constant current or constant voltage charging mode according to the real-time battery power;

[0074] Step 106, clear the adapter power level flag bit after the adapter is disconnected;

[0075] Step 107, when the adapter is reconnected, read the charging parameters stored by the adapter, set the charging current according to the charging parameters, and detect whether the real-time charging current exceeds the set range corresponding to the charging parameters; if not, maintain the current charging parameters; if so, re-execute the adapter power level identification process.

[0076] During the boot process, the charging IC can be initialized and the communication function can be verified to ensure normal communication between the charging IC and the system, laying a foundation for the subsequent adjustment of charging parameters. Detect the real-time charging current of the charging IC in the pre-charging mode and verify whether the charging working state is normal to ensure that the charging IC can work properly.

[0077] By collecting the charging current data of the charging IC multiple times, determine the power level of the adapter according to the continuous collection results, and set the adapter power level flag bit. After the setting is completed, save the data, set the flag bit to the power_supply power subsystem node, and report it to the system service. By obtaining this driver node, the system can identify the type of power adapter currently in use. After the identification is completed, set an appropriate charging current according to the value of the different adapter flag bits, and store the charging current as the charging parameter of the current adapter. For example, set a charging current of 1.8A for a 2A adapter and 2.8A for a 3A adapter. To protect the adapter, the charging current value needs to be lower than the rated current value of the adapter.

[0078] After the adapter is unplugged, the flag bit will be cleared to 0. When the adapter is detected to be inserted again, the stored charging parameters are preferentially written, and the real-time current value is read through the register of the charging IC. If the current value does not exceed the set value, the requirement is met; otherwise, the detection process is restarted. This method reduces the number of judgments in the software logic, improving the accuracy and stability.

[0079] This method of the present invention can automatically distinguish adapters of different powers using a software logic algorithm, adaptively set charging parameters, save charging configuration parameters, can protect the machine power management module in real time, and extend the machine life cycle. While reducing the input of manpower and material resources, the product can be continuously optimized.

[0080] In an optional embodiment of the present invention, initializing the charging IC and verifying the communication function includes:

[0081] Perform an initialization setting on the charging IC, and communicate with the charging IC to request to obtain the ID value of the charging IC;

[0082] If the ID value of the charging IC cannot be obtained, it is determined that the charging IC communication is abnormal;

[0083] If the ID value of the charging IC is successfully obtained, it is determined that the charging IC communication is normal.

[0084] In this embodiment, during the boot process, the charging IC is initialized and set, and communicated with it to read the ID value of the charging IC, so as to determine whether the communication is normal. The specific process includes: First, perform an initialization configuration on the charging IC to ensure that it is in an operable state; then, send a communication request to the charging IC to obtain its ID value. If the ID value cannot be successfully obtained, it indicates that the charging IC communication is abnormal and further troubleshooting is required; if the ID value is successfully obtained, it means that the charging IC communication is normal and it can work properly. This step ensures that the charging IC can reliably perform various functions during the subsequent charging process, providing a basic guarantee for adaptively adjusting the charging parameters.

[0085] In an alternative embodiment of the present invention, during the pre-charge mode, the real-time charging current of the charging IC is detected to verify the charging working state, including:

[0086] Enter the pre-charge mode at the initial stage of charging and set the pre-charge current at the battery terminal;

[0087] Detect whether the real-time charging current is consistent with the pre-charge current. If not, stop charging and prompt charging abnormality; if consistent, determine that the charging IC is working properly for charging.

[0088] In this embodiment, the charging IC first enters the trickle pre-charge mode and sets the pre-charge current at the battery terminal, such as 100 mA. By reading the registers of the charging IC and the registers of the fuel gauge inside the intelligent module, the real-time charging current data is obtained. The system will read the current data three times in a loop and compare it with the set pre-charge current. If the read current data is consistent with the set pre-charge current, it is considered that the charging IC is working properly and the subsequent charging process can continue; if the current data is inconsistent, it is determined that the charging IC is working abnormally, and the system will immediately stop charging and prompt charging abnormality. This step ensures the normal operation of the charging IC by detecting and comparing the charging current in real time.

[0089] In an alternative embodiment of the present invention, the charging current data of the charging IC is collected multiple times, and the power level of the adapter is determined according to the consecutive collection results, including:

[0090] Compare the charging current data with multiple increasing preset current thresholds in sequence. The multiple preset current thresholds include a first threshold, a second threshold, and higher-order thresholds, where each threshold corresponds to the boundary value of adjacent power levels;

[0091] If the consecutive comparison results are all less than or equal to the lowest-order first threshold, it is determined that the adapter is of the lowest power level;

[0092] If the consecutive comparison results are all greater than the Nth threshold and less than or equal to the (N + 1)th threshold, it is determined that the adapter is of the intermediate power level associated with the (N + 1)th threshold;

[0093] If the consecutive comparison results are all greater than the highest-order threshold, it is determined that the adapter is of the highest power level.

[0094] Refer to Figure 2, in this embodiment, the real-time current value of the charging IC is collected multiple times, and the power level of the adapter is determined according to the continuous acquisition results. The specific method is as follows: Compare the read charging current value with a preset threshold. For example, set a current value greater than 2.1A as the comparison benchmark. Since the maximum output of the adapter with the minimum power is 2A, such adapters can be screened out by setting a threshold higher than 2A. The system will compare the current value 3 times in a loop. If all 3 values are less than 2.1A, it is determined that the adapter is of the lowest power level with a rating of 2A; if all 3 values are greater than 2.1A, it is determined that the adapter is of the intermediate power level with a rating of 3A. And so on, by comparing the current values of different thresholds, adapters with higher power levels can be identified in turn. This method can accurately distinguish adapters with different powers through multiple comparisons and logical judgments, providing a reliable basis for setting subsequent charging parameters.

[0095] In an alternative embodiment of the present invention, switching between constant current and constant voltage charging modes according to the real-time battery power includes:

[0096] When the real-time battery power reaches the second preset power, adopt the constant voltage charging mode and gradually reduce the charging current according to the increase of the real-time battery power;

[0097] When the real-time battery power is between the first preset power and the second preset power, adopt the constant current charging mode and dynamically adjust the upper limit of the charging current according to the rated power of the adapter.

[0098] In this embodiment, corresponding judgment conditions are set according to the different real-time battery powers to switch between constant current and constant voltage charging modes. The system first obtains the real-time battery power value and adopts different charging strategies according to the power range. When the battery power is greater than or equal to 95%, the battery enters the constant voltage charging mode. At this time, the charging current begins to gradually decrease (based on measured data), and only by setting a charging current of 2A at the battery end can the charging requirement be met. When the battery power is between 1% and 95%, the system adopts the constant current charging mode, which occupies most of the charging process. In the constant current mode, the charging current can be appropriately increased, but not exceeding the rated power of the adapter, to ensure the safety and efficiency of the charging process. This segmented charging strategy can effectively optimize the charging efficiency while protecting the battery and the adapter.

[0099] In an alternative embodiment of the present invention, the method further includes:

[0100] Respectively set the maximum charging currents at the battery end and the adapter end according to the maximum output power inside the adapter;

[0101] Read the voltage at the adapter end, the voltage at the battery end, the charging current at the adapter end, and the charging current at the battery end in real time, synchronously save them to the power subsystem node, and report them to the system for real-time monitoring.

[0102] In this embodiment, according to the limitation of the maximum output power inside the adapter, the maximum charging currents at the battery end and the adapter end are set respectively. For example, the maximum value of the charging current at the battery end is set to 2.2A, and the maximum value of the charging current at the adapter end is set to 3.3A. After the parameter setting is completed, the system will read and read back in real time four key data: the adapter end voltage, the battery end voltage, the adapter end charging current, and the battery end charging current of the chip. These data will be synchronously saved to the node of the power_supply power subsystem and reported to the system for real-time monitoring. In this way, all parameters during the charging process can be comprehensively grasped.

[0103] In addition, the present invention can be adapted to multiple systems and has the following advantages in terms of versatility:

[0104] ① It has strong transplantation compatibility, is applicable to different android systems, and can be compatible with different interfaces.

[0105] ② It is automated, does not require manual intervention, uses software algorithms to implement logical judgment, and can also capture charging anomalies in a timely manner and notify the system.

[0106] ③ It is efficient and stable, adaptively sets charging parameters and saves data, and preferentially uses the stored data when the adapter is inserted next time, improving the detection efficiency and being stable.

[0107] Generally speaking, the present invention can keep the power management module in the product in an efficient and stable working state.
