ELECTRICAL STORAGE MODULE

摘要

An electricity storage module (10) is provided with a stack (30) formed by stacking a plurality of power storage elements (32) having positive and negative lead terminals (34) that protrude outward from end portions, holder members (40) made of an insulating resin and attached at least to, among the end portions of the power storage elements (32), the end portions from which the lead terminals (34) protrude, the holder members holding the power storage elements (32), and heat-transfer plate members (60) disposed between the power storage elements (32) adjacent in a stacking direction, the heat-transfer plate members being made of a heat conductive material for conducting heat generated by the power storage elements (32) to the outside. A heat-transfer plate engaging portion (44A) is provided in either the holder members (40) or the heat-transfer plate members (60), and an engaged portion (63A) for being engaged by an engaging portion (44A) is provided in the other. The holder members (40) and the heat-transfer plate members (60) are integrated by mutual engagement of the engaging portions (44A) and the engaged portions (63A).
