Abstract:
The present disclosure provides a battery module having more improved safety than the conventional battery pack and capable of protecting the battery cells more reliably. The current value at which a cell blocking portion CB inside each of a plurality of battery cells BC interrupts a current path inside the battery cell BC is larger than the current value at which the module fuse MF connected in series to the module terminals MT and the plurality of battery cells BC blows out.
