step 201, a charge pump control application in an electronic device reads an analog voltage value of a current battery and converts the analog voltage value into a digital voltage value;
step 202, based on the digital voltage value V bat Obtaining an initial target voltage value V1 required by the operation of the charge pump;

step 204, the charge pump control application reads the input voltage V2 of the charge pump chip once every certain interval;
here, the certain time may be set or adjusted according to design requirements. For example, the certain time is set to 200 milliseconds to 1 second.
Step 205, determining whether the voltage difference between the input voltage V2 and the stored target voltage V3 is within the preset error threshold range, and if yes, executing step 206; if not, go to step 207;
here, the error threshold range may be determined according to a voltage difference value accumulated during the last charging.
Step 206, taking the sum of the target voltage value V3 and the voltage step threshold S1 stored in the electronic device as a new target voltage value V3, and then executing step 208;

step 208, the new target voltage V3 is set to the power transmitting terminal for charging the electronic device, and at the same time, the stored target voltage V3 is updated.
Illustratively, the range of S1 is set to (50-100) millivolts, the preset error threshold range between the initial target voltage value V1 and the actual input voltage V2 is set to (-300, 300) millivolts, the V1 is set to the power transmitting terminal that charges the electronic device, and V1 is saved in the memory area of the electronic device, and the value is saved to the target voltage V3 stored in the memory area. The charge pump control application reads the actual input voltage V2 every 200 milliseconds to 1 second, and subtracts V2 from V3 to obtain a voltage difference value; if the voltage difference is within (-300, 300) millivolts, setting the sum of the target voltage value V3 and the voltage step threshold S1 as a new target voltage value V3 to the power transmitting end, and updating the V3 stored in the memory area to be the new target voltage value V3; if the voltage difference exceeds (-300, 300), the sum of the input voltage value V2 and the voltage step threshold S1 is set as a new target voltage value V3 to the power transmitting terminal, and V3 stored in the memory area is updated to the new target voltage value V3.
Therefore, compared with the method for adjusting the target voltage value based on the voltage difference value only, the method for adjusting the target voltage value by combining the voltage difference value and the preset error range can enable the charge pump chip to be in a stable charging state in the whole quick charging stage, and reduces the overall charging time.
