Movable Insulation Component for Battery Housing Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery housings with solid electrolytes face significant heat loss through cable ducts due to the high thermal conductivity of electrically conductive materials, which cannot be fully prevented by existing insulation methods, especially when connections are made.
Innovation Solution
A battery housing design featuring a movable insulation component that cuts off connections and thermally insulates contact elements when not in use, using a combination of thermal insulation materials and mechanical components to prevent heat dissipation, allowing for reversible connection restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact elements are permanently connected to enable continuous electrical connection, then electrical functionality is maintained, but heat loss through the connection increases significantly
Solution Approach 1:
The patent transforms the static permanent connection into a dynamic removable connection. The connection elements can be inserted when electrical functionality is needed and removed when insulation is prioritized, allowing the system to adapt between reliability and energy conservation based on operational requirements.
Solution Approach 2:
The patent applies different thermal properties to different parts of the connection system. The connection elements themselves are conductive when inserted, but the housing and surrounding structure remain highly insulated. This localized differentiation allows electrical connection without compromising overall thermal insulation performance.
2Adaptability or versatility
If data lines and coolant ducts pass through the battery housing, then necessary functional connections are established, but these create additional pathways for heat loss that cannot be prevented by insulation material
Solution Approach 1:
The patent extracts the data lines and coolant ducts from the insulated housing volume by providing removable connection elements that interface with the housing externally. This allows the housing insulation to remain continuous while enabling necessary functional connections to be made outside the insulated environment.

AI summary
A battery housing including at least one interior space for accommodating at least one battery, and including at least one contact element which, in a connection position, establishes a connection to a counter-contact element, the connection passing through the battery housing out of the interior space and/or into the interior space, the connection being cut off in an out-of-contact position with the counter-contact element, the counter-contact element being situated on an insulation component movable relative to the battery housing, which is movable from a first position, in which the counter-contact element and the contact element are in the connection position, into a second position, in which the counter-contact element and the contact element are in the out-of-contact position, the contact element being thermally insulated in the out-of-contact position by the insulation component.
