Battery assemblies, particularly for use in electric VTOL aircraft.

Abstract

The present invention relates particularly to a battery assembly (42) for use in an electric propulsion VTOL aircraft, the battery assembly (42) comprising a base plate assembly (44) and at least one battery stack assembly (20), each battery stack assembly (20) comprising a plurality of battery cells (12) stacked on the base plate assembly (20) along a stacking direction (S) and thus forming a battery cell stack (10) and electrically connected in parallel or series, and a housing (22) surrounding the battery cells (12) on all four sides, each battery stack assembly (20) comprising at least one barrier plate member (16) inserted between adjacent battery cells (12) and connected to the housing (22) to form at least two separate sealed modules (14) of the battery cells (12) within the corresponding battery stack assembly (20).
