BATTERY MODULE AND BUSBAR APPLIED FOR BATTERY MODULE

摘要

PURPOSE: A battery module is provided to obtain safety of use by easily braking a bus bar when an overcurrent flows in a battery module. CONSTITUTION: A battery module(1) comprises one or more unit cells; a case(300) for accommodating the unit cell; and a bus bar(200) which is electrically connected to the unit cell. The bur bar comprises a first metal plate; a second metal plate spaced from the first metal plate; and a metal bridge which connects the first metal plate and second metal plate, and has a lower melting point than the metal plate. The metal bridge is a smokeless alloy including tin and copper as main ingredients.
