Abstract:
1. A member for measurement of cell voltage and temperature in a battery pack, comprising: temperature measuring elements (a) adapted for being attached to the surfaces of unit cells of the battery pack, wherein each of the temperature measuring elements comprise a sensing body coupled to connection feet; and a printed circuit board (b) having protrusions formed at an upper end thereof such that the protrusions are suited for connecting to electrode lead connection members that connect electrode leads of the unit cells, the electrode lead connection members being bus bars connecting the electrode leads, the printed circuit board comprising connection parts formed at a lower part thereof for connecting the temperature measuring elements to the printed circuit board, and a circuit for transmitting electric current for voltage measurement of the unit cells and electric current for temperature measurement of the temperature measuring elements; wherein attachment of the voltage and temperature measuring member to the battery pack is accomplished by attaching the protrusion of the voltage and temperature measuring member to the bus bars of the battery pack such that temperature measuring elements are located on the unit cells of the battery pack.
