STRUCTURAL BATTERY COMPRISING COOLING CHANNELS

A battery assembly (9) for an electric vehicle comprises two spaced-apart longitudinal profiles (6,7) extending in a length direction L, interconnected to a front and a rear transverse beam (40,50). At least three beam shaped battery modules (15-18) are interconnected along their longitudinal sides (26-29) via a plate-shaped interconnecting member (35,36), and extend in the length direction, to be attached to an inner surface (42) of the front transverse beam (40) via a bracket (43,48). [0002] Each battery module (15-18) is provided with cooling channels (23,24) extending it the length direction L and having an inlet (55,56) situated between a transverse end face (59,60) of the module and the inner surface (42) of the front transverse beam (40). [0003] A water inlet duct (52,53) extends from an external side the front transverse beam (40) in a central area situated between the brackets (43,48), for connecting to a coolant inlet of the central battery module (16,17). [0004] Connecting areas on the external side of the front transverse beam (40) are provided for attaching to a front frame part (2,45,46) being situated adjacent to the central area, opposite the brackets (43,48), and a branching duct (54) extends between a front transverse side (60) of the central module (16,17) to an inlet (55,56) that is situated between the transverse end face (59) of the side modules (15,18) and the front transverse beam (40) via a channel (57,67) through the bracket (43,48).
