Title:
POWER STORAGE MODULE
Document Type and Number:
WIPO Patent Application WO/2012/015068
Kind Code:
A1
Abstract:
Provided is a power storage module in which life-shortening damage to the module is prevented by restricting increases in the temperature of the module due to the generation of heat, the characteristics of the module are maximized by homogenizing the cell temperature, and a level of insulation compliant with the required safety specifications can be achieved. The power storage module (11) of the present invention is provided with a case (21), a plurality of stack plates (41), a heat-transferring metal plate (51), and a heat-radiating fin (61). The case (21) has an exposure opening (23) in the side of the case (22), and houses a plurality of storage cells (31). The stack plates (41), which have an opening (42), are interposed between the plurality of storage cells (31), and the position of each of the stack plates is determined by the engagement with the adjacent stack plates. The heat transferring metal plate (51) has a flat section (52) and a bent section (53), and is arranged so as to be in close contact with the principle surface (33) of the power storage cell (31). The heat radiating fin (61) protrudes from the exposure opening (23) to the exterior of the case (21), and is thermally coupled to the bent section (53) of the heat transferring metal plate (51) at surface contact state via a heat transferring insulation sheet (65).
