Electrical storage module

摘要

An electricity storage module includes a stack, holder members, and heat-transfer plate members. The stack is formed by stacking power storage elements having lead terminals protruding outward from end portions. The holder members are made of insulating resin and are attached to the end portions of the power storage elements, the holder members holding the power storage elements. The heat-transfer plate member are disposed between power storage elements adjacent in a stacking direction, the heat-transfer plate members made of heat conductive material. An engaging portion is provided on one of the holder members and the heat-transfer plate members, and an engaged portion arranged to be engaged by the engaging portion is provided on the other of the holder members and the heat-transfer plate members. The holder members and the heat-transfer plate members are integrated by mutual engagement of the engaging portions and the engaged portions.

主权项

1. An electricity storage module comprising:
a stack formed by stacking a plurality of power storage elements having positive and negative lead terminals that protrude outward from end portions thereof; holder members made of an insulating resin and attached at least to the end portions of the power storage elements from which the lead terminals protrude, the holder members being arranged to hold the power storage elements; and heat-transfer plate members disposed between power storage elements that are adjacent in a stacking direction of the stack, the heat-transfer plate members being made of a heat conductive material configured to conduct heat generated by the power storage elements to outside of the module, wherein an engaging portion is provided on one of the holder members and the heat-transfer plate members, and an engaged portion arranged to be engaged by the engaging portion is provided on the other of the holder members and the heat-transfer plate members, wherein the holder members and the heat-transfer plate members are integrated by mutual engagement of the engaging portions and the engaged portions, and wherein the holder members are formed with slide portions on which the heat-transfer plate members are slidably mounted.
