Fig. 3 is a flowchart of an implementation of a third embodiment of a charging processing method provided by the present invention, and as shown in fig. 3, the method includes:
step 301: reading the electrical parameters of the connecting wire;
here, taking the electrical parameter of the connection line (charging line) as one consideration in determining the input to the electronic device during charging, a memory/chip for storing the electrical parameter is provided in the connection line in this embodiment. The electrical parameters of the connecting wires are read from the memory chip/device. The electrical parameters may specifically be the voltage range, current range, temperature range, and resistance (impedance) or resistance (impedance) range of the connection line. It will be appreciated by those skilled in the art that the voltage/current/temperature ranges from a minimum value for the corresponding electrical parameter to a maximum value for the corresponding electrical parameter. In practical use, the maximum voltage, the maximum current and the maximum temperature are applied more; of course, the electrical parameters also include other parameters used during charging, such as the superconducting rate.

If the range of current that can be borne by the charging wire 1 is higher than 4.8A, the battery of the electronic device receives the input of the charging input parameter 5A (target input parameter) so that the self-electricity quantity gradually tends to be sufficient.
The above description is made by taking an electrical parameter as an example of voltage, and the description made by taking current, temperature or other parameters is similar to the above scheme, which is not listed here. In a word, the matching judgment of the electronic equipment in the charging process can enable the electronic equipment to quickly finish charging according to the input mode of the matching result, and the charging efficiency is greatly improved.
In the above scheme, the stored electrical parameters of the charging wire are read, the electronic device judges whether the charging input parameters are matched with the electrical parameters of the connecting wire, and the parameters matched with the electrical parameters of the connecting wire are determined according to the judgment result so that the electronic device can be normally charged. The electrical parameters of the charging lines are used as a reference factor for determining the input of the electronic device during the charging process, i.e. the influence of the electrical parameters of the connecting lines (charging lines) on the charging process is taken into account. The benefits of this are: the electronic equipment carries out the adjustment of input parameter according to the electrical parameter of charging wire, can satisfy the demand of carrying out intellectuality, the management that becomes more meticulous to charging.

That is, the present embodiment is directed to a case where the charging device charges the electronic device through the connection line, the charging device outputs charging energy to the electronic device through the connection line, and the electronic device receives the output energy of the charging device through the connection line so that the battery capacity in the electronic device is gradually in a sufficient state. The charging equipment outputs energy to the electronic equipment by outputting the charging output parameters, and the electronic equipment receives the charging energy output by the charging equipment by charging input parameters.
Fig. 4 is a flowchart of an implementation of a fourth embodiment of a charging processing method provided by the present invention, and as shown in fig. 4, the method includes:
step 401: reading the electrical parameters of the connecting wire;
here, taking the electrical parameter of the connection line (charging line) as one consideration in determining the input to the electronic device during charging, a memory/chip for storing the electrical parameter is provided in the connection line in this embodiment. The electrical parameters of the connecting wires are read from the memory chip/device. The electrical parameters may specifically be the voltage range, current range, temperature range, and resistance (impedance) or resistance (impedance) range of the connection line. It will be appreciated by those skilled in the art that the voltage/current/temperature ranges from a minimum value for the corresponding electrical parameter to a maximum value for the corresponding electrical parameter. In practical use, the maximum voltage, the maximum current and the maximum temperature are applied more; of course, the electrical parameters also include other parameters used during charging, such as the superconducting rate.
Step 402: acquiring a charging pre-output parameter of the charging equipment or acquiring a charging pre-input parameter of the electronic equipment;
step 403: adjusting the charging pre-output parameter of the charging equipment according to the electrical parameter of the connecting line to obtain a target output parameter of the charging equipment, so that the charging equipment outputs energy to the electronic equipment based on the target output parameter; or adjusting the charging pre-input parameters of the electronic equipment according to the electrical parameters of the connecting line to obtain target input parameters of the electronic equipment.
Here, the charging pre-output parameter of the charging device or the charging pre-input parameter of the electronic device is adjusted according to the electrical parameter of the charging line to obtain the target output parameter of the charging device or obtain the target input parameter of the electronic device, so that the charging process is guaranteed to be efficiently completed through the target output parameter of the charging device and the target input parameter of the electronic device.
As an embodiment, the adjusting the charging pre-output parameter of the charging device according to the electrical parameter of the connection line to obtain the target output parameter of the charging device includes:
acquiring attribute parameters of the electronic equipment; estimating electrical parameters of the connecting line according to attribute parameters of the electronic equipment to obtain first estimation parameters; obtaining a target output parameter of the charging equipment based on the first estimation parameter; and sending the target output parameters to the charging equipment through a connecting line so that the charging equipment charges the electronic equipment by outputting the target output parameters. That is, according to the attribute parameters of the electronic device, the resistance (impedance) parameters of the connection line connected under the current connection are estimated, and according to the estimation result, the target output parameters of the charging device, specifically, the target output voltage/current, are obtained.
The acquiring of the attribute parameters of the electronic device includes:
reading at least one input voltage parameter of the electronic device;
reading at least one set of impedance parameters of the electronic device (each set comprising at least two impedance parameters);
correspondingly, the estimating the electrical parameter of the connection line according to the attribute parameter of the electronic device to obtain a first estimation parameter includes:
calculating impedance parameters of at least one connecting line according to at least one input voltage parameter and at least one group of impedance parameters of the electronic equipment;
determining the impedance parameter of one connecting line or the average value of the impedance parameters of two or more connecting lines as a first estimation parameter;
correspondingly, obtaining the target output parameter of the charging device based on the first estimation parameter includes:
comparing the first estimated parameter to a first predetermined value;
when the first estimation parameter is larger than a first preset value, increasing a pre-output parameter of the charging equipment, and determining the increased pre-output parameter as a target output parameter of the charging equipment;
and when the first estimation parameter is smaller than the first preset value, reducing the pre-output parameter of the charging equipment, and determining the reduced pre-output parameter as the target output parameter of the charging equipment.
In the above scheme, consider: the resistance of the charging wire read can be a specific value or a range of values. The resistance of the charging wire is in a range value, so that the charging wire is matched with different charging devices for use; on the other hand, Vin of the electronic equipment is fixed and unchangeable within a period of time, and to achieve high charging efficiency, the change of the resistance is calculated according to the change of Vin, namely a reasonable resistance value is selected from the resistance range value through calculation, and the output of the charging equipment is reasonably adjusted according to the resistance value, so that on one hand, the charging efficiency can be met, and on the other hand, the requirement of reducing loss caused by the existence of the resistance on a charging line as much as possible can be met; and the charging wire can be used with different specifications charging equipment in a matched manner, charging overheating, damage and other phenomena cannot be caused, and intelligent and fine management of charging can be met.
The foregoing is further described with reference to fig. 6.
In fig. 6, on the electronic device side, a control circuit is added in addition to the battery circuit. The control circuit comprises resistors R1 and R2 and a switch 1; the battery circuit includes resistor R3, switch 2, and a battery.
In the charging process, Vin of the electronic device is fixed and unchangeable within a period of time, when the Vin changes, the impedance of the charging line needs to be calculated every other section for achieving the high efficiency of charging, and the output of the charging device is reasonably adjusted according to the resistance value, so that the smooth completion of the charging process is ensured.
During charging, the switch 2 in the battery circuit is turned to the position 3, and the switch 1 of the control circuit is turned to the position 2, that is, the control circuit is in an off state during charging, and only the charging input current Vin is directly input to the battery through the R3 to charge the battery.
When the electronic device learns that Vin has changed (becomes V' in), switch 2 of the battery circuit is turned from position 3 to position 4, and switch 1 of the control circuit is turned from position 2 to position 1, i.e. the battery circuit is not charged and is in an off state. In this case, the electronic device reads the resistances of the resistors R1 and R2 in the control circuit, obtains the charging output parameter Vbus of the charging device through a USB-PD protocol (USB Power Delivery Specification, universal serial bus charging protocol), and then calculates according to the formula (1), to obtain the estimated impedance Rx of the charging line:
the resistance values of the resistors R1 and R2 are a group of resistance parameters and are attribute parameters of the electronic equipment; vbus is an input voltage parameter of the electronic device, and is an attribute parameter of the electronic device.
The foregoing is the estimated impedance Rx that the electronic device derives from knowing one Vbus. In consideration of the accuracy of estimation of the impedance of the charging lines, at least two Vbus may be known, the impedance of one charging line is calculated according to formula (1) for each of the known Vbus, and the calculated impedance values of all the charging lines are averaged, thereby obtaining a final estimated impedance value (first estimation parameter) of the charging line. Next, the electronic device compares the first estimated parameter with a predetermined ideal impedance value (first predetermined value);
when the first estimated parameter is larger than or equal to the first preset value, the actual resistance of the charging line is larger than the ideal resistance value, so that the energy consumed on the charging line is increased, in order to ensure the normal operation of the charging process, the output parameter of the charging equipment such as Vbus/Ibus needs to be increased, and the increased Vbus/Ibus is sent to the charging equipment by the electronic equipment through the charging line, so that the charging equipment charges the electronic equipment by using the increased Vbus/Ibus. The charging equipment charges the electronic equipment by using the increased Vbus/Ibus, the energy consumed on a charging line is taken into consideration, the electronic equipment is charged by using the increased Vbus/Ibus, and the charging of the electronic equipment is not influenced even if the output energy of the charging equipment is consumed on the charging line; that is, the increased Vbus/Ibus is used to integrate the voltage/current consumed on the charging line, and the output voltage/current (Vbus/Ibus) of the charging device can still maintain the input voltage/current (Vin/Iin) expected by the electronic device when the voltage/current consumed on the charging line reaches the electronic device side.
When the first estimated parameter is smaller than the first preset value, the actual resistance of the charging line is smaller than the ideal resistance value, so that the energy consumed on the charging line is smaller, the output parameter of the charging equipment at the moment can be properly reduced, and normal charging can be guaranteed. The electronic equipment reduces the pre-output parameter of the charging equipment, determines the reduced pre-output parameter as the target output parameter of the charging equipment, and sends the reduced Vbus/Ibus to the charging equipment through a charging wire, so that the charging equipment charges the electronic equipment by using the reduced Vbus/Ibus. Thus, efficient charging is achieved on the basis of no energy waste.
The increasing and decreasing amplitudes of the pre-output parameters can take any reasonable values, and are not particularly limited.
After the target output parameter of the charging device is adjusted by the electronic device for V' in, the electronic device controls the switch 2 in the battery circuit to be turned to the position 3, and controls the switch 1 in the battery circuit to be turned to the position 2, that is, the charging process is started in the charging process. And the charging equipment charges the electronic equipment by using the adjusted output parameters.
In the scheme, the electrical parameters (impedance values) of the connecting line are estimated according to the attribute parameters (R1, R2 and input voltage parameters) of the electronic equipment to obtain a first estimation parameter (impedance average value); obtaining a target output parameter of the charging equipment based on the first estimation parameter; and sending the target output parameters to the charging equipment through a connecting line so that the charging equipment charges the electronic equipment by outputting the target output parameters. The accurate impedance value of the charging line connected under the current connecting condition with the charging equipment and the electronic equipment can be obtained through accurate estimation of the impedance value of the connecting line; the target output parameter of the charging equipment can be accurately adjusted according to the impedance value so as to efficiently charge the electronic equipment.
