Module for an electric energy storage assembly

Module comprising a casing comprising at least two opposite walls and at least one different wall other than said two opposite walls, at least two electric energy storage assemblies (20) being arranged in a plurality of lines respectively in said casing so that their axis of revolution are perpendicular to said two opposite walls (12, 13) of the casing (10), said at least two electric energy storage assemblies being connected by connection means, and at least one electronic board (40) for energy management and diagnosis of the energy storage assemblies is arranged in said casing,

• wherein
• said two opposite walls (12, 13) and said at least one different wall (14) of the casing, are electrically insulated,
• one of the two opposite walls (12, 13) being in physical contact with heat dissipation elements (15) which are connected to the electric energy storage assemblies (20), while said one of the two opposite walls is not in physical contact with the electronic management board,
• said at least one different wall (14) being in physical contact with the electronic management board, while said at least one different wall is not in physical contact with the heat dissipation elements (15), and
• said electric energy storage assemblies being in thermal contact with one of the two opposite walls by the way of the heat dissipation elements, while the electronic management board is in thermal contact with said different wall in order to promote cooling of said module.
