Resumen de: WO2026125986A1
An electric battery unit, for example a battery pack or a single module contained in a battery pack, comprises a housing (4) and a plurality of battery cells (2) within the housing (4), which are configured and arranged to come into direct contact with a flow of a temperature-regulating liquid that passes through the housing (4) for maintaining the battery cells (2) within a determined temperature range. The temperature-regulating liquid flows from an inlet collector chamber (5), which extends below the battery cells (2), through the spaces (7) between the battery cells (2) and up to an outlet collector chamber (6) which extends above the battery cells (2). The inlet collector chamber (5) communicates with the spaces (7) between the battery cells via a plurality of relatively restricted passages (9), which offer the flow of the temperature-regulating liquid sufficient resistance to prevent the temperature-regulating liquid from tending to flow to a greater extent in the spaces that are closer to the inlet and/or the outlet for the temperature-regulating liquid. The inlet collector chamber (5) is defined by the internal cavity of a rigid hollow body (50), constituting an element independent of the structure of the housing (4), disposed inside the housing (4) below the battery cells (2). The rigid hollow body (50) has an inlet (5A) for the temperature-regulating liquid and an upper wall with a distribution of apertures (9) that define said restricted passages.
