NOVEL BUS BAR FOR ELECTRIC CONNECTION AND BATTERY MODULE COMPRISING THE SAME

摘要

A bus bar simultaneously performs electrical connection between unit cells and detection of voltage of the unit cells in a battery module having the same and includes: vertical bent parts formed by bending opposite ends of a strip-shaped bar body in the same direction, the vertical bent parts being provided with coupling grooves or protrusions; and a horizontal bent part formed by bending one of the vertical bent parts toward the bar body such that the horizontal bent part is parallel with the bar body. The electrode terminals of the unit cells are connected to the rear surface of the bar body of the bus bar, whereby the electrical connection between the unit cells is accomplished, and the horizontal bent part of the bus bar is directly connected to a battery management system for monitoring the potential difference and the temperature of the unit cells to control the unit cells.
