Commonly used single battery test methods

What are the commonly used single battery testing methods? Extending the service life of the single battery is the key to improving the power of the battery and electrical equipment, because the performance of the single battery is very important to the overall performance of the battery. In order to manage and utilize each battery on a larger scale, it is necessary to continuously monitor the status of each battery. The following are the most common ways to test a single battery. What are the commonly used single battery testing methods? 1. The resistance partial pressure method is also a common method to judge the quality of a single battery. Among them, the resistance partial pressure method is one of the commonly used detection methods. In the detection process, the actual voltage is first attenuated to the range that the measuring chip can withstand by means of the partial voltage of the resistance, and then the analog-to-digital conversion is performed on it. It is necessary to note that the local voltage resistance test method is that a certain error will occur as the number of single cells increases. 2. Floating measurement Floating measurement is also an effective single cell detection method at present. When measuring the battery terminal voltage, the window comparator will automatically determine the current low level. Under the appropriate low potential, the analog-to-digital conversion will start and measure directly. When the low potential is too high or too low, the low potential is floated through the mathematical model through the microcontroller. 3. The method of analog switch If you want to use the analog switch method to test a single battery, usually first select the channel to be measured. Then the output of the analog switch is sent to adc through the voltage follower for conversion test. Under normal circumstances, the analog switch method can select the appropriate magnification according to the total voltage of the battery in series. In addition to the above three commonly used battery detection methods, various other advanced methods can also be used to detect individual batteries in practical applications. Therefore, if you want to know how the single battery service is, you can also know whether the quality and service provided by the single battery manufacturer are trustworthy from the perspective of battery testing.
