BATTERY PACK

摘要

The present invention relates to a battery pack, and disclosed is a battery pack comprising: a pair of battery cells respectively having anode and cathode electrodes formed on the front ends thereof; a plurality of battery modules having battery cells accommodated in a tubular case of which a front end and a base are open, and having a first cover provided to the base of the case and closed, and including bus bars electrically connected with the electrodes of the battery cells protruding from the case; a battery pack housing for accommodating the plurality of battery modules; voltage sensing units respectively and electrically connected to the bus bars of the battery modules accommodated in the battery pack housing, and sensing voltages of the battery cells; slave BMS modules electrically connected to the voltage sensing units so as to adjust voltage deviations of the battery cells and sense the temperature; and a second cover provided on the battery pack housing so as to prevent the voltage sensing units and the slave BMS modules from being exposed to the outside.
