Abstract
The present invention relates to a battery module that includes a probe for detecting expansion of a battery cell. More particularly, the present invention relates to a battery module including: two or more of rechargeable battery cells; a sensing probe provided at an external surface of at least one of the battery cells to sense a local expansion change of the battery cell and transmitting a signal; and a controller receiving the signal from the sensing probe, estimating an internal pressure of the battery cell from the received signal, and generating a warning signal to assure safety of the battery module when the estimated internal pressure exceeds a threshold pressure level.
