Abstract
A power train battery assembly of an electric, fuel-cell or hybrid vehicle, said assembly having a plurality of battery cells (16), each encased in an individual and externally-closed cell housing (18), that are combined into a cell stack and moreover having at least one pipe (36) conducting cooling fluid for the removal of heat energy from the battery cells (16). At least one heat-conducting fin (42) that originates from the pipe (36) flatly abuts, at least in sections, at least one cell housing (18).

Power train battery assembly of an electric, fuel-cell or hybrid vehicle, said assembly having a plurality of battery cells (16), each encased in an externally-closed cell housing (18), that are combined into a cell stack and moreover having at least one pipe (36) conducting cooling fluid for the removal of heat energy from the battery cells (16), characterized by at least one heat-conducting fin (42) that originates from the pipe (36) and that at least sections flatly abuts at least one cell housing (18).
Power train battery assembly of an electric, fuel-cell or hybrid vehicle, said assembly having a plurality of battery cells (16), each encased in an externally-closed cell housing (18) of its own, as well as having at least one pipe (36) which conducts cooling fluid and is laterally flattened in sections in the region of an adjacent battery cell (16).
Power train battery assembly of an electric, fuel-cell or hybrid vehicle, said assembly having a plurality of battery cells (16), each encased in an individual, externally-closed cell housing (18), that are combined into a cell stack (16) and moreover having at least one pipe (36) conducting a zeotropic coolant for the removal of heat energy from the battery cells (16), the pipe section positioned within the assembly being designed so that the coolant therein undergoes a decrease in pressure in such a manner that the saturation temperature of the coolant in the pipe section substantially remains constant.
Power train battery assembly of an electric, fuel-cell or hybrid vehicle, said assembly having a plurality of battery cells (16), each encased in an individual and externally-closed cell housing (18), that are combined into a cell stack (16) and moreover having a plurality of pipe sections (82, 84) conducting an azeotropic coolant that, within the assembly, are in direct thermal contact and are flowed through in a counter-current manner.
