Design and Implementation of New Smart Battery Management System

摘要

The purpose of the battery management system is to improve the efficiency and prolong cycling life of the battery pack which is connected in series, SH79F329 is used as the main control IC of the hardware. The system can detect the voltage, current, temperature of the battery by AD sampling, and can calculate the SOC by the value of current and the way of SOC algorithm, as well as communicating with the host computer and it has been implemented in the process of charging equalization, overcharge protection, overdischarge protection and a series of other processes. It proves that this design has high reliability and real-time performance in the test.
