Abstract
The present invention relates to a system for diagnosing a battery cell by using a direct BMS, and more particularly, to a system for diagnosing a battery cell by using a direct BMS, in which the direct BMS physically and electrically makes direct contact with an electrode of each of battery cells to measure a voltage of each of the battery cells and currents of the battery cells, calculate an impedance of each of the battery cells based on the measured voltage and the measured current, diagnose a state of each of the battery cells through the impedance, and wirelessly transmit a diagnosis result to a master BMS.
