<P>PROBLEM TO BE SOLVED: To provide a surface pressure distribution detector for laminated batteries, capable of detecting a surface pressure distribution without deteriorating power generation performance. <P>SOLUTION: The surface pressure distribution detector includes an inner insulated section 61 elastically deformable in a laminating direction of a unit cell 10; a plurality of first electrodes 63 disposed on one of side surfaces of the inner insulated section 61; a plurality of second electrodes 62 disposed on the other side surface of the inner insulated section 61 and facing the first electrodes 63; a pair of outer insulated sections 64 disposed between the first electrodes 63 and the unit cell 10 on the first electrode side, and disposed between the second electrodes 62 and the unit cell 10 on the second electrode side; and a plurality of conductive sections 65 configured elastically deformable in the laminating direction, electrically insulated from the first electrodes 63 and the second electrodes 62, and electrically connecting the unit cell 10 on the first electrode side and the unit cell 10 on the second electrode side. A surface pressure distribution measuring section 90 calculates a laminated surface pressure based on a capacitance changing according to a distance between the first electrodes 63 and the second electrodes 62 to obtain a laminated surface pressure distribution. <P>COPYRIGHT: (C)2011,JPO&INPIT |
