Abstract: This deformation detection sensor for a sealed secondary battery comprises: a polymer matrix layer attached to an exterior body among members constituting a battery; a casing sandwiching the exterior body together with the polymer matrix layer; a spacer layer sandwiched, along with the polymer matrix layer, between the exterior body and the casing; and a detection unit detecting a change in the external field arising in response to a deformation of the polymer matrix layer. When C is the surface area on a placement surface of the exterior body for attaching the polymer matrix layer and the spacer layer, A is the contact surface area between the placement surface and the polymer matrix layer, and B is the contact surface area between the placement surface and the spacer layer, the relationship 0.15≤(A+B)/C≤1 is established.

Abstract: According to the present invention, the residual capacity in a fully-charged state is measured for each of a plurality of batteries (A, B, C) which become candidates to constitute a serial body (step S11). Then, the batteries (A, B) to constitute the serial body are selected from among the candidate batteries (A, B, C) on the basis of the residual capacities (step S12). Here, only the batteries (A, B), wherein the absolute value of the difference between the residual capacity and the maximum residual capacity of each battery is within 10% of the maximum residual capacity, are selected from among the batteries constituting the serial body. Then, the serial body is formed by connecting only the selected batteries (A, B) in series (step S13).
