<P>PROBLEM TO BE SOLVED: To provide a battery pack capable of enhancing an assembling property, and having light weight, low cost, and high reliability. <P>SOLUTION: The battery pack is equipped with a frame body holding a plurality of unit cells 14 each having a positive electrode at one end and a negative electrode at the other end. The frame body is comprised of two outer frames 2 having the same shape and an inner frame 3. The unit cells 14 constituting the battery pack 1 are arranged on both sides of the inner frame 3, and one outer frame 2 and the other outer frame 2 are arranged so as to interpose the unit cell 14 between the inner frame and itself. Two outer frames 2 are connected to the inner frame 3 by a side connection part 23 and upper and lower connection parts 24. Positive terminal bus bar, a negative terminal bus bar, and a between-unit cell bus bar for electrically connecting the unit cells 14 in series, and a voltage detecting lead wire 4 with connector for detecting the voltage of the unit cells 14 are fixed to the inner frame 3. <P>COPYRIGHT: (C)2007,JPO&INPIT |
