| 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.
