Abstract (en)
[origin: WO2020216516A1] The invention relates to a battery housing assembly (2), in particular in the form of a battery housing assembly (2) of a vehicle traction battery (1) which can be temperature-controlled using a fluid, comprising - a battery housing (4) which encloses an interior (5) for receiving a plurality of battery cells (3); and - a heat transfer device (6) which has an inlet (19), an outlet (20), and at least one fluid channel (7) arranged fluidically between the inlet and the outlet, wherein the fluid (8) can flow through the heat transfer device (6) from the inlet (19) to the outlet (20) via the at least one fluid channel (7), and - the at least one fluid channel (7) is arranged in the interior (5), and the contact side (10) of the fluid channel can be pressed against at least one contact element (9) for the battery cells (3) in order to transfer heat; and - at least one expansion element (11) which undergoes an expansion when the fluid (8) in the heat transfer device (6) is pressurized in order to press the at least one fluid channel (7) against the at least one contact element (9) by pressing on a support surface (16).
