Abstract

An electric battery pack comprises a container (2) including a bottom wall (2A), side walls (2C) and an upper lid (2B). Within the container are disposed assemblies of battery cells (4) arranged side by side and spaced apart from one another. A temperature-regulating system uses a temperature-regulating liquid that flows from an inlet collector chamber (11) located below the battery cells (4), through the spaces (9) defined between the battery cells (4), into an outlet collector chamber (13) arranged above the battery cells (4). The temperature-regulating system includes a heat exchanger (6) to maintain the temperature of the temperature-regulating liquid within a determined range. The heat exchanger consists of a heat exchange plate (6), including one or more passages (15) for a secondary fluid, which is associated with the lid (C) or the bottom wall (2A) of the container (2), so that the flow of the temperature-regulating liquid comes into contact with the heat exchange plate (6) inside the container (2). In a preferred example, the heat exchange plate (6) is associated with the lid (C) of the container (2), in such a way as to constitute a lower wall of the outlet collector chamber (13) of the temperature-regulating liquid, and is furthermore arranged in contact with upper surfaces of the battery cells (4), in such a way that the heat exchange plate (6) is able to exchange heat both with the flow of the temperature-regulating liquid and with the battery cells (4) that are in contact with it.
