Battery Pack Conductive Module Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery pack designs are hindered by the size due to the interposition of cases made of synthetic resin, which makes it difficult to miniaturize the battery pack.
Innovation Solution
A conductive module with a housing member that houses the circuit protection member, first and second electrical connection structural bodies, and a mounting structure that engages with insulating members to securely attach the module to the battery cells, allowing for a more compact design by eliminating the need for an additional case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a case made of synthetic resin is provided to collectively attach the conductive modules, then the conductive modules are securely attached to the battery module, but the size of the battery pack increases making miniaturization difficult
Solution Approach 1:
The patent removes the separate synthetic resin case from the structure by integrating its attachment function directly into the conductive module housing. The housing member now performs both the protective enclosure function and the attachment function through integrated engagement bodies, eliminating the need for an additional external case and reducing overall battery pack size.
Solution Approach 2:
The patent combines the functions of the housing member and the attachment mechanism into a single integrated structure. The engagement bodies (conductor-side and battery-side) are built into the housing member itself, merging the protective housing function with the mounting attachment function, thereby eliminating the need for a separate synthetic resin case.
2Volume of stationary object
If the housing member directly engages with insulating members without a separate case, then the battery pack size is reduced, but the protection against external inputs may be compromised
Solution Approach 1:
The housing member integrates both the protective enclosure function and the attachment function into a single component. The engagement bodies are built into the housing member itself, which maintains protection against external inputs while enabling direct attachment to insulating members without requiring a separate synthetic resin case.

AI summary
A conductive module includes a first conductive member electrically connected to an electrode terminal of a battery cell; a second conductive member that electrically connects a battery monitoring unit monitoring a battery state to the first conductive member; a circuit protection member arranged between the first conductive member and the second conductive member; a first electrical connection structural body electrically connecting the first conductive member and the circuit protection member; a second electrical connection structural body electrically connecting the second conductive member and the circuit protection member; a housing member housing the circuit protection member and the first and second electrical connection structural bodies; and a mounting structure that mounts the housing member to an insulating member with the insulating member sandwiching the battery cell as a mounting target. The mounting structure includes a conductor-side engagement body which is an engagement body provided in the housing member.
