Battery voltage flexible acquisition method

Abstract

This invention relates to a flexible battery voltage acquisition method. Based on the presence of various complex voltage acquisition harnesses and connecting cables of different lengths on battery modules within an energy storage battery box, it proposes a method that uses the same single-cell battery management system to switch between different types of battery modules, thereby changing the voltage acquisition node and improving voltage acquisition accuracy. Simultaneously, it can also determine whether there is an abnormal battery voltage based on the read values ​​using corresponding algorithms, and can also identify abnormal voltage acquisition circuits.
