Based on STM32 Battery Charging Post SOC Intelligent Measurement System Design

In order to further improve on the battery management system technology, the paper takes STM32 chip as the core control chip, and proposes a set of charging pile state of charge (SOC, State of Charge) measurement system design program. The thesis firstly introduces the SOC acquisition circuit during battery operation, and secondly, starting from the program writing, details the hardware acquisition circuit design of the system, the program implementation process of the main control program, battery sampling module, data transmission module and LCD module. Practical application proves that the design can realize the function of monitoring the battery power of the charging pile, ensure the stable and safe operation of the battery in the process of using and charging, and then effectively extend the service life of the battery.
