Individually Detachable Energy Storage Modules for Motor Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle energy storage systems require complex replacement of individual modules, as multiple modules must be removed even if only one is defective, leading to increased repair complexity.
Innovation Solution
The apparatus features individually detachable energy storage modules with a main body that allows for independent removal and replacement of defective modules without disassembling other modules or the entire system, utilizing a frame-like main body, carrier means with wedges for non-positive fastening, electrical connections, coolant ducts, and a sealing plate for simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple energy storage modules are fastened together in a fixed configuration, then the system structure is stable and robust, but the repair complexity increases because multiple modules must be removed even if only one is defective
Solution Approach 1:
The energy storage system is divided into individually detachable modules, each with its own carrier means. The carrier means can be detached from the main body independently, allowing single module replacement without removing other modules. This segmentation enables maintenance of individual components while preserving the overall system structure.
2Ease of operation
If the entire main body is dismantled to replace a single module, then complete system access is achieved, but the repair time and complexity increase significantly
Solution Approach 1:
The defective module is extracted from the system by detaching only its carrier means from the main body, while other modules remain in place. This selective extraction allows access to and replacement of individual modules without dismantling the entire main body structure, significantly reducing repair time.
3Adaptability or versatility
If all carrier means are detached to replace one module, then full module accessibility is achieved, but the disassembly complexity and time loss increase
Solution Approach 1:
The fastening system is segmented into individual carrier means, each capable of independent attachment and detachment from the main body. This segmentation provides full accessibility to each module through simple individual carrier detachment, without requiring complex disassembly procedures or detachment of other carriers.

AI summary
An apparatus for storing electric energy for a motor vehicle includes a plurality of energy storage modules and a main body which can be fastened to the motor vehicle. Each energy storage module includes energy storage for storing the electric energy and a carrier, in which the energy storage is arranged. The carrier is fastened in an individually detachable manner to the main body in the state in which it is fastened to the motor vehicle, with the result that a first one of the energy storage modules can be removed from the apparatus without it being necessary for the carrier of a second one of the energy storage modules to be detached from the main body.
