Abstract

An electric battery pack comprises one or more electric battery units (1), each including an array of battery cells (2) arranged inside a container (4) and kept spaced apart from each other by respective spacer frames (8). A temperature-regulating liquid distribution system includes an inlet collector chamber (5) disposed below the array of battery cells (2) and an outlet collector chamber (6) disposed above the array of battery cells (2) and communicating with the inlet collector chamber (5) through the spaces (7) defined between the battery cells (2). Each space (7) between the cells (2) communicates with the inlet collector chamber (5) via one or more relatively narrow passages (9). The cells (2) each have a positive pole (3P) and a negative pole (3N) on a vertical end wall of the cell, facing a vertical side wall (40) of the container (4). The positive poles (3P) and negative poles (3N) of the cells are contained in one or more lateral chambers (CP, CN) of the battery unit (1), which are isolated from the space of the container occupied by the cells (2) by a separation wall (D) including a sealing panel (10) made of elastomeric material, for example silicone material, mounted on the ends of the cells (2) bearing the positive poles (3P) and negative poles (3N), and a rigid support frame (11) for the sealing panel (10), rigidly connected to the container (4). One or more rigid tubular elements (12) are associated with the sealing panel (10) for communication between the inlet collector chamber (5) and the lateral chambers (CP, CN).
