Detachable Wiring Connection for Battery Pack Design Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs have limited design flexibility due to the constraints imposed by wiring configurations for monitoring battery cell voltage, which restricts the configuration of battery modules within the pack case.
Innovation Solution
An energy storage apparatus with a detachable wiring connection component that allows for flexible connection of first and second wiring, enabling easy reconfiguration and simplification of the apparatus by attaching or removing the component as needed, and facilitating connection between different energy storage devices with varying configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wiring is wired from battery cell electrode terminal to outside the pack case for monitoring voltage, then voltage monitoring function is achieved, but design flexibility of battery module configuration is limited
Solution Approach 1:
The battery pack is divided into multiple battery modules, each with its own module case. The wiring system is segmented to connect individual battery cells within modules and then connect modules together in series, allowing independent configuration of each module while maintaining overall system functionality.
Solution Approach 2:
The wiring system is designed with universal connectors and standardized connection points that can accommodate different battery module configurations. The same wiring structure can serve multiple functions: monitoring voltage of individual cells, providing series connections between modules, and allowing flexible reconfiguration of the battery pack layout.
2Ease of operation
If battery modules are configured with fixed wiring arrangements for voltage monitoring, then monitoring reliability is ensured, but reconfiguration and simplification become difficult
Solution Approach 1:
The wiring system incorporates detachable connectors and flexible routing that allow the battery pack to be dynamically reconfigured. Modules can be added, removed, or rearranged while maintaining reliable electrical connections, enabling the system to adapt to different operational requirements without compromising monitoring reliability.
3Device complexity
If wiring is constrained to specific paths for monitoring purposes, then connection reliability is maintained, but device complexity increases
Solution Approach 1:
The wiring system uses a nested structure where individual cell connections are contained within module cases, module-level connections are organized separately, and pack-level connections are established through standardized interfaces. This hierarchical nesting simplifies the overall wiring structure while maintaining reliable connections at each level through dedicated connection points.
