Abstract

An electric battery unit (1) comprises a container (2) and a plurality of battery cells within the container (4) spaced apart from each other by one or more spacer frames (11) such as to define spaces (7) between the cells (2). The battery cells (2) come into direct contact with a flow of a temperature-regulating liquid that passes through the container (4) from an inlet collector chamber (5) below, or above, the battery cells (2), through the spaces (7) between the battery cells (2), up to an outlet collector chamber (6) above, or respectively below, 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), configured to offer the flow of the temperature-regulating liquid a sufficient resistance to prevent the temperature-regulating liquid from tending to flow to a greater extent in the spaces that are closer to an inlet and/or an outlet for the temperature-regulating liquid. The spacer frames (11) define a plurality of parallel paths (13) in each of the spaces (7) between the cells (2) configured so as to further uniform the temperature of each cell along the vertical direction.
