Abstract
A battery module includes a cell stack including stacked pouch-type secondary battery cells, which have electrode leads in opposite directions; a bus bar frame having first and second vertical plates and an upper plate connected to the first and second vertical plates to be hinged to at least one of the first and second vertical plates; and a mono-frame having a rectangular tube shape with an inner space in which the cell stack mounted to the bus bar frame is disposed. A plurality of bus bars are provided at outer surfaces of the first and second vertical plates, and the electrode leads of the cells are electrically connected to the corresponding bus bars through slots formed in the first and second vertical plates. A sensing member electrically connected to the bus bars of the vertical plates to sense electrical characteristics of the cells is disposed at the upper plate.
