摘要： A battery module which uses a flexible printed circuit board (FPCB) to provide a transmission path of information on the voltage or temperature thereof sensed by a bus bar. The battery module may have a smaller size in a height direction compared to a case of using a rigid printed circuit baord (RPCB) or a wire instead of the FPCB to provide the transmission path of the information on the voltage or temperature, and may thus have improved energy efficiency per volume.
