Abstract

An electric battery pack (100) comprises a plurality of stacks (101) of battery cells arranged within a container (4). In each cell stack (101), a temperature-regulating liquid flows from an inlet collecting chamber (13A), which extends below the cell stacks, through the spaces between the cells (2) and up to an outlet collecting chamber (13B) that extends above the cells (2) of the stack (101). The battery pack (1) includes a distribution system (D) configured to enable a major flow of the temperature-regulating liquid, corresponding to most or all of the incoming flow into the battery pack, to be cyclically supplied only to one of the cell stacks (101), or only to a group of cell stacks (101), while the other cell stacks (101) receive a reduced or no flow of the temperature-regulating liquid, such that, at the end of each cycle, a plurality of cell stacks (101) have in turn received, for a determined time interval, most or all of the incoming flow of thermal management liquid into the battery pack (1).
