1. An assembly comprising:
a plurality of cells (10) or of groups (100) of cells of an electric vehicle battery (1), of which at least:
a first cell and a second cell separated from each other by a gap (15), or
a first group of cells and a second group of cells separated from each other by a gap (115),
at least two of:
at least one first fluid passage (17, 117) passing in said space (15, 115), and located between two opposing first sides (11a, 13; 111a, 113a) which face each other:
on the first cell and of the second cell (11, 13) respectively, or
on the first and second groups (111, 113) of cells respectively, the first passage (17, 117) being connected to a first supply (27) of fluid to be circulated in thermal exchange with the first and second cells or the first and second groups of cells,
at least one second fluid passage (19, 119) located on second sides (11b, 111b, 113b):
of the first cell and of the second cell respectively, or
of the first and second groups of cells respectively, and,
at least one peripheral passage (21) of fluid located around the cells (10) or groups (100) of cells, in thermal exchange with them, on sides (643) thereof other than said first sides (11a, 13;111a, 113a) of the cells or groups of cells, respectively, said peripheral fluid passage (21) being connected to an additional supply (25) of fluid to be circulated in thermal exchange with said cells or groups of cells, and
a thermal insulator (33) located such that said second fluid passage (19, 119) and/or the peripheral fluid passage (21) is interposed between the thermal insulator (33) and:
at least the first and second cells, or
at least the first and second groups (640′) of cells,
the second fluid passage (19, 119) being connected to a second supply (29) of fluid to be circulated in thermal exchange with the first and second cells or with the first and second groups of cells.
