Abstract

An electric battery unit (1), comprising an array of battery cells (2) arranged side by side within a housing (4) of the battery unit, wherein each cell (2) comprises an external housing (6) provided with a vent valve (17) configured to allow the exit from the housing of gases formed inside the cell when said gases exceed a predetermined pressure and/or a predetermined temperature, following the cell entering a thermal runaway condition, and wherein said housing (4) of the battery unit comprises a venting device, configured to rupture or deform so as to leave free a vent opening (18) provided in a wall (20, 26) of the housing (4) in case the pressure and/or temperature inside the housing (4) exceed predetermined threshold values. The battery unit (1) comprises a shield (34, 47, 62) disposed within said housing (4) and extending facing said vent opening (18) of the housing (4) in an intermediate position between the vent opening (18) and the cell (2) of said array of battery cells closest to said vent opening (18), in such a way that, when said venting device ruptures or deforms, said shield (34, 47, 62) defines, together with the walls (20, 26) of said housing (4), a passage (44, 54) for the gases, coming from said vent valves (17) and directed towards said vent opening (18) of the housing (4), spaced apart from the battery cell (2) closest to the vent opening (18).
