High-voltage battery

Abstract

The invention relates to a high-voltage battery (100) comprising a battery housing (110) with an actively cooled housing wall (112) lying in a longitudinal plane (xy112), an active cooling arrangement (120) adjacent to the actively cooled housing wall (112) for cooling the actively cooled housing wall (112), a plurality of battery cells (40) stacked in a longitudinal plane in the battery housing (110), each having a flat distal cell wall (42), wherein the distal cell walls (42) lie in a single longitudinal plane (xy42) and are spaced apart from the inner side (112') of the actively cooled housing wall (112), wherein the space between the distal cell walls (42) and the associated actively cooled housing wall (112) is filled by a cured thermal conductivity compound (12) with a specific thermal conductivity L12.and wherein several thermal insulator elements (200, 200', 200") embedded in the thermal conductivity (12) are provided between at least some distal cell walls (42) and the actively cooled housing wall (112), which have a specific insulator thermal conductivity L20 that is at least 30% lower than the specific thermal conductivity L12 of the thermal conductivity, so that the effective local thermal conductivities Leff between the distal cell wall (42) of the respective battery cell (40) and the actively cooled housing wall (112) are different from each other.
