Abstract

An electric battery pack (1) comprises a plurality of electric battery groups. Each group comprises a plurality of battery cells (4), arranged side by side along a first horizontal direction (X). The different groups of battery cells (4) are arranged in at least one row along a second horizontal direction (Y) orthogonal to the first horizontal direction (X). The battery pack (1) is configured to receive a flow of a temperature-regulating liquid that passes through the battery pack (1) so as to come into direct contact with the battery cells (4). A system for distributing the temperature-regulating liquid includes a longitudinal feeding channel (6) and a plurality of transverse channels (7) extending beneath each group of battery cells (4) along said first horizontal direction (X). The transverse channels (7) are defined by a lower support structure (5) on which the battery cells (4) are supported and including a lower wall (50), an upper wall (51) parallel to and spaced above the lower wall (50) and formed integrally, or rigidly connected, with said lower wall (50), and a plurality of internal ribs (5B) parallel to and spaced apart from each other extending along the first horizontal direction (X) between the lower wall (50) and the upper wall (51). Each transverse channel (7) has a closed cross-section, defined by the lower wall (50), the upper wall (51), and two of the internal ribs (5B) of the lower support structure (5). In the upper wall (51) of the lower support structure (5) are formed relatively narrow apertures (9) for communication with the spaces between the cells (4).
