<p>A battery module is provided to enhance an accuracy of information on a physical operation state thereof by fitting detection units in respective battery cells, and ensure the safety of the battery module in a simple structure and with high precision. A battery module(100) is a medium and large-size battery module comprising many battery cells(201,202). The each battery cell has a detection unit(301,302) for monitoring a change in the physical operation state of the battery cell. The detection units are connected in series and joined to a control part(400) of the battery module. A signal(a detected signal) detected in each battery cell is integrated into the detected signals for all battery cells and transmitted to the control part.</p> |
