Problems solved by technology

The disadvantage is that flexible adaptation and / or shaping is not possible, especially for installation in batteries
Also, an insulating element with its brittle mica panels and its short-fiber fiber mats may crack and / or shatter easily due to uncontrolled heat build-up and associated pressure build-up, thus causing damage to the surrounding environment and / or premature loss of Its insulation function
Finally, a high weight per unit area is especially detrimental to vehicles

Embodiment Construction

[0064] Figure 1A The proposed multilayer thermal insulation element 1 is shown in a schematic cross-sectional view not to scale. Figure 1B and Figure 1C A further embodiment of the proposed multilayer thermal insulation element 1 is shown in a schematic sectional illustration, also not to scale. The illustrated embodiments are similar to one another and can also be combined with one another as desired. in particular different Figure 1A , Figure 1B and Figure 1C Used only to highlight different preferred aspects.

[0065] The thermal insulation element 1 is especially designed as a flat stack.

[0066] The insulating element 1 is in particular compressible and at the same time bendable.

[0067] The term "bendable" is preferably understood to mean that the bending stiffness of the insulating element 1 is sufficiently low, where bending stiffness is a measure of the force acting against bending deformation of the component or of the insulating element 1 . Bending sti...

Abstract

The invention relates to a multi-layer thermal insulation element for thermally insulating a battery, comprising a first cover layer, a second cover layer and a compressible and/or flexible intermediate layer arranged between the cover layers, said intermediate layer having at least one heat-resistant fiber layer, wherein the fiber layer is formed from a needled nonwoven fabric and/or wherein thecover layers are flexurally weak and the thermal insulation element is overall compressible and flexible.

Description

technical field [0001] The invention relates to a multilayer thermal insulation element for thermal insulation of batteries according to the preamble of claim 1 , a battery with a multilayer thermal insulation element according to the preamble of claim 35 , and a preamble according to claim 49 Use of multilayer thermal insulation elements in the sequence section. Background technique [0002] In the present invention, the term “insulation element” is preferably understood to mean a flat part composed of a layer structure, in particular a laminate, which is designed and / or used for thermal insulation of a battery. In particular, the insulating element is configured to reduce and / or delay the release of heat to the environment, in particular to the vehicle interior, and / or to block or reduce or delay heat in the battery in the event of uncontrolled or excessive heat generation in the battery diffusion. [0003] In the present invention, the term "battery" is understood to me...
