Abstract

The invention provides a power storage module and a method of manufacturing the same. The power storage module can hold a plurality of power storage units without looseness, and can reduce the amountof movement of the power storage unit when an acceleration input from the stack direction of the power storage unit is input, thereby improving the reliability of electrical connection. In the power storage module (1), a plurality of power storage units (3) are housed in a cell housing (2); in the cell housing (2), a plurality of unit accommodating spaces (27) having parallel wall surfaces (23a,26a) are arranged straightly in the arrangement direction of the parallel wall surfaces (23a,26a); in the unit accommodating spaces (27), the power storage units (3) are accommodated and sheet-like pressing members (4) which apply pressing force towards the wall surfaces (23a,26a) to the power storage units (3); the power storage units (3) are configured to between the pressing members (4) and the wall surfaces (23a,26a).

Description

technical field [0001] The invention relates to an electric storage module and a manufacturing method of the electric storage module. Background technique [0002] A power storage module mounted in a hybrid car, an electric vehicle, etc. is formed by stacking a plurality of power storage cells. As an electric storage unit, in addition to housing a battery element including a positive electrode and a negative electrode in a metal cell can, there is also known a battery element enclosed in a resin laminate film. The electric storage unit has a pair of positive and negative electrode terminals externally, and the electrode terminals of adjacent electric storage units are electrically connected in series or in parallel by using a bus bar. [0003] The power storage module mounted on the vehicle is subjected to vibrations such as when running, and the power storage unit becomes loose, which may impair the reliability of the electrical connection between the power storage units o...
