BATTERY CELL INTERCONNECTION BOARD HAVING PACKING FOR PROTECTING INFLOW OF FOREIGN SUBSTANCES

摘要

The present invention relates to a battery cell interconnection board with an inflow preventing member preventing an inflow of external foreign materials as a bus bar for the electrical connection of battery cells and the detection of voltages of the battery cells. In a battery cell assembly where the battery cells are arranged to be parallel to closely adhere or adjoin to each other, the battery cell interconnection board includes: at least one bus bar having an electrode terminal connection unit where battery cell electrode terminals are electrically connected to each other and a printed circuit board (PCB) connection unit formed in one end of the electrode terminal connection unit to detect the voltages and transmit the information of the detected voltages to a PCB; the PCB where a cell voltage temperature node (CVTN) connector for transmitting the voltage information received through the PCB connection unit of the bus bar is formed; and a base frame where the bus bar and the PCB are mounted and insertion through-holes are formed. The battery cell electrode terminals are inserted into the insertion through holes from the lower side to connect the battery cell electrode terminals to the bus bar. The inflow preventing member preventing the inflow of the external foreign materials through the insertion through-holes by having one end fixated to the insertion through-hole and the other end electrically coming into contact with an outer surface of the battery cell electrode terminal inserted into the insertion through-hole from the lower side is additionally installed in the insertion through-hole.
