Battery voltage measurement based on microcontroller and its application in battery life evaluation
Abstract
This paper designs and implements a battery current measurement system based on STM32. This system can monitor the working status of the battery in real time and evaluate the status of the battery based on the data obtained from voltage measurement. The system is mainly composed of two parts: one part is the voltage and current monitoring module, and the other part is the display module. With the help of the voltage and current monitoring module, the voltage and current conditions of the battery can be precisely monitored at any time. The single-chip microcomputer can quickly calculate some key parameter values, and the display module will show the voltage, current and other values, which makes it convenient for people to check the status of the battery. By using sensors with relatively high precision to measure the voltage and current of the battery, And by relying on the single-chip microcomputer to process the obtained information in a timely manner, the status of the battery can be monitored and calculated better and more promptly. In this way, abnormal discharge conditions of the battery, as well as battery damage or aging problems can be detected in a timely manner. The price of this device is not high. It can be widely applied in various types of batteries and is quite convenient to use. Through conducting experimental tests, the various functions of this system have been verified. That is, it can evaluate whether the battery state is good based on the measured voltage and current, which is conducive to extending the service life of the battery. The foundation for reducing the maintenance cost of batteries has been laid.
