Abstract
Exterior thermal battery-cover for a battery housing characterised in that the cover comprises at least a thermal insulating layer with a thermal resistance (R-value) of at least 0.070 m2·K/W, preferably with a thermal resistance of at least 0.078 m2·K/W and whereby the thermal insulating layer is at least one of a fibrous layer, an open cell foam layer or closed cell foam layer.
Claims16
An exterior thermal battery cover for a battery housing, comprising:
- a thermal insulating layer with a thermal resistance (R-value) of at least 0.070 m2·K/W, wherein the thermal insulating layer is a porous fibrous layer made of a porous fibrous material comprising staple fibers and/or filaments and a binder;
- and
- wherein the porous fibrous layer is moulded to form a panel with a density of between 150 and 600 kg/m3, a thermal conductivity between 0.03 and 0.06 W/mK and a thickness of between 2.5 and 10 mm.
