Measuring cell phone battery power 1. Voltage test method is relatively simple, and it is obtained by simply monitoring the battery voltage. But the battery power and voltage are not linear, so this test method is not accurate. Especially when the battery level of the mobile phone is less than 50%, this method is very inaccurate. 2. Battery modeling method. This method is to build a data table based on the discharge curve of the battery. The data table will indicate the power value under different voltages. This method can effectively improve the accuracy of the measurement. However, it is not easy to obtain an accurate data sheet, because the relationship between voltage and power also involves factors such as battery temperature, self-discharge, and aging. Only by combining many factors to make corrections can a more satisfactory power measurement be obtained. 3. The coulomb counter connects a current detection resistor in series with the positive and negative poles of the battery. When there is current flowing through the resistor, the coulomb counter will induce induction. The current flowing through the battery can be calculated through the detection and induction, so it can be accurate to track the battery. The accuracy can reach 1% when the power changes. It is the most accurate battery power detection method. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
