That is, step 011 and step 013 can be implemented by the microprocessor 21, and step 012 can be implemented by the first analog-to-digital conversion module 22.
Specifically, the charging system 100 may include an adapter 20; or the charging system 100 may include the adapter 20 and the terminal 30, and the adapter 20 may be a power adapter, which may be connected to the terminal 30 through a connection line to enable communication with the terminal 30 and charging the terminal 30.

Or, the microprocessor 21 may determine whether to enter the fast charging stage or stop the fast charging to enter the normal charging stage according to the battery parameter, for example, enter the fast charging stage when the battery capacity is less than 80%, and enter the normal charging stage when the battery capacity is greater than or equal to 80%. When entering the fast charging stage and stopping the fast charging and entering the ordinary charging stage, the corresponding fast charging start signal and the corresponding fast charging stop signal may be sent to the application processor 31. In addition, the microprocessor 21 may also collect abnormal information of the adapter 20, and send an abnormal signal to the application processor 31 when an abnormal condition occurs (such as the battery parameter cannot be acquired, the adapter 20 cannot be charged, etc.), so that the application processor 31 executes a corresponding process, such as disconnecting the terminal 30 from the adapter 20.
During the communication process (including the normal charging phase and the fast charging phase), the microprocessor 21 may continuously read the battery parameter through the first analog-to-digital conversion module 22. Specifically, the terminal 30 is provided with a sensor related to the battery 33, and can acquire an analog signal (i.e., a first battery parameter) of information such as a battery voltage, a battery current, and a battery temperature. The first battery parameter is sent to the adapter 20 via the connection 40 and converted into a second battery parameter by the first analog-to-digital conversion module 22, in which the analog signal is converted into a digital signal. The first analog-to-digital conversion module 22 is a 16-bit differential analog-to-digital signal converter, and the data conversion precision is high, so that the accuracy of the second battery parameter is high. An external electricity meter does not need to be arranged on the terminal 30, and miniaturization of the terminal 30 is facilitated. In addition, during the conversion process, the microprocessor 21 processes the battery parameter, for example, calculates the battery capacity according to the battery current and the charging duration, so as to obtain a second battery parameter containing more battery parameters.

That is, step 014 and step 015 may be implemented by the application processor 31.
Specifically, after the adapter 20 and the terminal 30 are connected, the terminal 30 determines whether the adapter 20 is a matching adapter 20, and before the adapter 20 is not determined to be a matching adapter 20, the terminal 30 does not give control to the adapter 20 to allow the microprocessor 21 to control the adapter 20 to perform quick charging in order to ensure charging safety.
In the determination process, the application processor 31 controls the adapter 20 to perform charging in a normal charging stage, the application processor 31 first obtains the third battery parameter, for example, the application processor 31 can directly obtain the third battery parameter through the platform electricity meter, because the current is small in the normal charging stage, the accuracy of the obtained third battery parameter is high, the application processor 31 can perform charging control in the normal charging stage accurately by matching with the platform electricity meter, and the accuracy of displaying the electric quantity according to the third battery parameter is also high.

0143: the first battery parameter is converted to a third battery parameter by a second analog-to-digital conversion module 34 of the application processor 31.
Referring again to fig. 5, in some embodiments, the second obtaining module 14 is configured to perform step 0141; or the second acquiring module 14 is also used for steps 0142 and 0143. That is, the second obtaining module 14 is configured to read the second battery parameter stored in the register 24 of the microprocessor 21 through the application processor 31 as the third battery parameter; or the second obtaining module 14 is further configured to obtain the first battery parameter through the application processor 31; the first battery parameter is converted to a third battery parameter by a second analog-to-digital conversion module 34 of the application processor 31.
In some embodiments, the microprocessor 21 is provided with a register 24, and the application processor 31 is provided with a second analog-to-digital conversion module 34; the application processor 31 is further configured to read the second battery parameter stored in the register 24 as a third battery parameter; alternatively, the application processor 31 is further configured to obtain a first battery parameter; the second analog-to-digital conversion module 34 is configured to convert the first battery parameter into a third battery parameter. That is, step 0113 may be implemented by the application processor 31, or step 0114 and step 0115 may be implemented by the application processor 31.
Specifically, the application processor 31 is further provided with a second analog-to-digital conversion module 34, after obtaining analog signals (i.e., first battery parameters) such as battery voltage, battery current, and battery temperature acquired by sensors related to the battery 33, the application processor 31 may perform analog-to-digital conversion through the second analog-to-digital conversion module 34 to convert the first battery parameter into a third battery parameter, and during the conversion process, the battery power may be calculated according to the battery current and the charging duration, so as to obtain a second battery parameter including more battery parameters.
Or, since the microprocessor 21 is provided with the register 24 to store each battery parameter, for example, the battery current register is provided to store the battery current, the battery voltage register is provided to store the battery voltage, the battery temperature register is provided to store the battery temperature, and the battery power register is provided to store the battery power, so that the application processor 31 can obtain the second battery parameter stored in the register 24 of the microprocessor 21 after establishing a communication connection with the microprocessor 21, the application processor 31 is not required to separately obtain and convert the first battery parameter, the computing resource of the application processor 31 is saved, and compared with the second analog-to-digital conversion module 34 of the application processor 31, the first analog-to-digital conversion module 22 of the microprocessor 21 is a 16-bit differential analog-to-digital signal converter, the sampling precision is higher, and the obtained second battery parameter is more accurate than the third battery parameter, therefore, the application processor 31 directly reads the second battery parameter stored in the register 24 of the microprocessor 21 as the third battery parameter, so as to improve the accuracy of the battery parameter, thereby realizing more accurate charging control and electric quantity display.
Referring to fig. 3 and 8, in some embodiments, the charging control method further includes the following steps:
016: when the terminal 30 enters a fast charging stage, recording the first electric quantity of the terminal 30 and clearing the second battery parameter stored in the register 24 in the microprocessor 21;
017: calculating a second amount of power based on the first amount of power and a second battery parameter in the register 24 during the rapid charging phase; and
018: the current power of the terminal 30 is displayed according to the value of the second power.
Referring to fig. 9, in some embodiments, the charging control apparatus 10 further includes a recording module 16, a calculating module 17, and a display module 18. The recording module 16, the calculating module 17 and the displaying module 18 are used for executing step 016, step 017 and step 018 respectively.

That is, step 016, step 017 and step 018 can be realized by the application processor 31.
Specifically, when the terminal 30 enters the fast charging phase, the application processor 31 gives control to the microprocessor 21, the microprocessor 21 performs charging control in the fast charging phase, and the application processor 31 can display the power of the terminal 30 according to the charging power to indicate the current charging condition (e.g. display the current power percentage of the battery 33 in real time).
The application processor 31 may perform battery power display according to a third battery parameter obtained by converting the first battery parameter by the second analog-to-digital conversion module 34. Because the current is in the condition of fast charging of large current, the accuracy of the acquired third current parameter is low, and the displayed electric quantity may not be matched with the actual electric quantity, so that the accuracy of electric quantity display is reduced.
Therefore, the application processor 31 can obtain the battery power by means of the high-precision first analog-to-digital conversion module 22 of the microprocessor 21, so as to improve the accuracy of power display.
Specifically, when the terminal 30 enters the fast charging stage, the application processor 31 records the current first electric quantity of the terminal 30, and then controls the microprocessor 21 to clear the originally retained historical battery parameters in the register 24, so that the battery parameters stored in the subsequent register 24 are all the battery parameters obtained in the fast charging stage, and therefore, sufficient storage space of the register 24 can be ensured, no historical battery parameters exist, and the efficiency of data reading can be improved.
Then, when displaying the electric quantity, the application processor 31 superimposes the first electric quantity and the battery electric quantity accumulated in the register 24 to obtain a second electric quantity, where the second electric quantity is the current electric quantity of the terminal 30, and the application processor 31 can display the current electric quantity of the terminal 30 according to the second electric quantity to complete electric quantity display. Therefore, the second electric quantity with higher accuracy can be obtained without wasting the computing resources of the application processor 31 to obtain the third battery parameter alone, and the accuracy of electric quantity display is improved.
Referring to fig. 3 and 10, in some embodiments, the charging control method further includes:
019: after each calculation of the second electrical quantity, the second battery parameter in the register 24 is cleared and the value of the second electrical quantity is assigned to the first electrical quantity.
Referring to fig. 11, in some embodiments, the charging control apparatus 10 further includes a clearing module 12, and the clearing module 12 is configured to execute step 019. That is, the clearing module 12 is configured to clear the second battery parameter in the register 24 after each calculation of the second power amount, and assign the value of the second power amount to the first power amount.
In some embodiments, the application processor 31 is further configured to clear the second battery parameter in the register 24 and assign the value of the second power to the first power after each calculation of the second power. That is, step 019 may be implemented by the application processor 31.
Specifically, in order to ensure time synchronization between the power of the register 24 and the power of the terminal 30, the second battery parameter in the register 24 is cleared each time the application processor 31 reads the second battery parameter in the register 24 to update the display power according to the calculated second power. After the second electric quantity is obtained through calculation each time so as to update the display electric quantity, the second battery parameter accumulated in the register 24 is cleared, the calculated second electric quantity is assigned to the first electric quantity, the second battery parameter (such as the battery electric quantity) accumulated in the register 24 is obtained between every two adjacent times of reading the second battery parameter, and the value of the first electric quantity when the second electric quantity is calculated is always the value of the second electric quantity obtained through previous calculation, so that the accuracy of obtaining the second electric quantity through calculation each time is ensured, and the accuracy of displaying the electric quantity is further ensured.
For example, after entering the fast charging phase, the application processor 31 records the first power (e.g. 50% in percentage) of the terminal 30 at the time, and at intervals of a predetermined time (e.g. 5S, 6S, 10S, 60S, etc.) during the fast charging, the application processor 31 calculates the second power to update the display power. If the predetermined time is 6S, after entering 6S of the fast charging phase, the application processor 31 acquires the battery power from the register 24 for the first time (e.g. 0.1%), then calculates a second power according to the battery power and the first power, where the second power is equal to the sum of the first 6S battery power and the first power (i.e. the second power is 50% + 0.1% — 50.1%), clears the battery power acquired by the first 6S register 24 after the calculation is completed (i.e. the battery power of the register 24 at this time becomes 0), and assigns the second power to the first power (the first power at this time becomes 50.1%); after 6S, the battery power (for example, 0.1%) is obtained from the register 24 for the second time, then the second power is calculated according to the battery power and the first power, where the second power is 50.1% + 01% — 50.2%, after the calculation is completed, the battery power obtained from the register 24 in the second 6S is cleared (that is, the battery power of the register 24 becomes 0 again at this time), and the second power is assigned to the first power (where the first power becomes 50.2%), so that the above process is repeated, and the second power after the nth predetermined time period can be obtained, where N is a positive integer.
In other embodiments, a register 24 for storing the second charge may be separately provided, and the microprocessor 21 may be capable of accumulating the first charge upon entering the fast charge to determine the second charge. The second amount of power is then stored in the register 24 and the application processor 31 retrieves the second amount of power directly from the register 24 for display of the amount of power. Not only can the computing resources of the application processor 31 be saved, but also the accuracy of the second electric quantity acquired by the application processor 31 can be ensured without performing electric quantity synchronization processing on the application processor 31 and the microprocessor 21 due to the second electric quantity directly calculated by the microprocessor 21.
