The invention relates to a battery unit (1) essentially comprising a plurality of cells, a housing (3) receiving and surrounding said cells, and means (5) for regulating the temperature of said cells by circulation of a heat-transfer fluid. Said battery unit (1) is characterised in that the housing (3) comprises, at least in a bottom region on which the cells are arranged, at least one, preferentially several, heat exchange zones for heat exchange between said cells and the heat-transfer fluid, said at least one zone being built into the structure of said housing (3), preferentially in the wall thereof.
