AI Technical Summary
Technical Problem
In power storage devices, refrigerant leakage from the connection between the heat exchanger and refrigerant piping can lead to adhesion on the power storage elements, potentially causing adverse effects.
Method used
A partition wall is positioned between the refrigerant piping and the energy storage elements, with through-holes and inclined portions guiding leaked refrigerant away from the elements, and a protective member covers the housing to manage gas discharge.
Benefits of technology
The configuration effectively prevents refrigerant adhesion to the energy storage elements, ensuring reliable operation and safety by managing refrigerant leakage.

Abstract
This suppresses the adhesion of refrigerants used in heat exchange systems to energy storage elements. [Solution] The energy storage device comprises a plurality of energy storage cells 29, a heat exchange plate 32 positioned between the plurality of energy storage cells 29 and facing the long sides of the plurality of energy storage cells 29, and extending in the longitudinal direction of the long sides, a main supply pipe 37A for circulating a refrigerant to the heat exchange plate 32, and a housing case that houses the plurality of energy storage cells 29, the heat exchange plate, and the main supply pipe 37A. The housing case 10 is provided with a partition wall 22 positioned between the main supply pipe 37A, which is connected to the heat exchange plate 32, and the energy storage cells 29 when viewed from above.
