PURPOSE: A battery pack is provided to improve stability by lower the output voltage of the battery pack to the level of a battery module to reduce ignition or electric shock. CONSTITUTION: One or more battery modules(100) are composed of a plurality of battery cells(10). An anode terminal(11) and a cathode terminal(12) of the battery cell are coupled to a bus bar(15). A relay(20,30) is installed in a connection line(21) between the battery modules and an output line(31,41) of the battery module. A battery controller(200) controls battery cells by being connected to the relays. A detection sensor includes an impact sensing sensor for an airbag(50a,50b,50c), an impact sensing sensor(70a,70b) and a moisture sensing sensor(60). |
