SYSTEM OF ESTIMATING STATE OF HEALTH FOR BATTERY AND METHOD THEREOF

摘要

The present invention relates to a system for predicting the lifespan of a battery. The present invention configures a closed circuit in the battery, which one or more battery cells are coupled to, in a voltage measuring mode not in a state that the battery is charging, and compares an input pulse value inputted through the closed circuit after outputting the pulse of a set level, thereby calculating the remaining service life of the battery through the calculated resistance value.
