Abstract

An electric battery pack (1) comprises one or more groups of battery cells (2) arranged inside a container (4). The battery cells (2) are cylindrical cells (2) or pouch cells arranged horizontally and immersed in a flow of a temperature-regulating liquid that maintains them within a predetermined temperature range. The temperature-regulating liquid flows from an inlet collector chamber (5), situated below the battery cells (2), through spaces (7) defined between the cells (2), into an outlet collector chamber (6) arranged above the cells. The spaces between the cells communicate with the inlet collector chamber (5) via a plurality of restricted passages (9). The battery cells (2) each have their respective positive and negative poles (P, N) situated at a same end, or on opposite ends, of the cell, facing a respective vertical side wall (40) of the container (4). All the poles (P, N) of the cells that are facing a respective vertical side wall (40) of the container (4) of the battery pack (1) are contained in one or more lateral chambers (C). The temperature-regulating liquid can flow from the inlet collector chamber (5) to the outlet collector chamber (6) also passing through the lateral chambers (C), which are isolated from the spaces (7) between the cells (2) by means of a separation wall (D) including a sealing panel (10) of elastomeric material, for example of silicone material, mounted on the ends of the cells (2) bearing the poles (P, N). Associated with the sealing panel (10) and/or with a rigid support frame (11) of the sealing panel are one or more rigid tubular elements (12) for the communication of the inlet collector chamber (5) with each lateral chamber (C).
