Power Storage Module Layout With Internal Connector Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power storage modules are bulky due to the outward projection of connector arrangement sections, which increases their overall size.
Innovation Solution
The power storage elements are arranged such that their electrode surfaces face each other, with a conductive member and wiring module disposed between them, both within the outline of the elements, eliminating the need for external projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector arrangement section projects outward from the outline of the power storage elements, then the connector can be arranged in the power storage module, but the power storage module increases its size as a whole
Solution Approach 1:
The connector arrangement section is nested within the outline of the power storage elements by utilizing the space between adjacent power storage elements. The connector is arranged in this interstitial space rather than projecting outward, allowing the connector to be integrated into the internal structure of the power storage module without increasing its external dimensions.
2Reliability
If the conductive member is disposed between adjacent power storage elements to electrically connect electrode surfaces, then electrical connection is achieved, but space for connector arrangement is reduced
Solution Approach 1:
The conductive member is designed with differentiated functional zones: one region makes electrical contact with the electrode surfaces of adjacent power storage elements, while another region provides space for the connector arrangement. This local differentiation allows the conductive member to simultaneously fulfill both electrical connection and connector accommodation functions without compromising either requirement.

AI summary
A power storage module includes power storage elements having electrode surfaces of positive electrode surfaces and negative electrode surfaces on front and back surfaces thereof, a conductive member electrically connected to the electrode surfaces of the power storage elements, and a wiring module electrically connected to the conductive member. The power storage elements are arranged in an arrangement direction such that the electrode surfaces of the power storage elements that are adjacent to each other are opposed to each other. The electrode surfaces of the power storage elements that are adjacent to each other are electrically connected by the conductive member that is disposed between the power storage elements that are adjacent to each other. The wiring module is disposed between the power storage elements that are adjacent to each other. The conductive member and the wiring module are disposed inside an outline of the power storage elements seen from the arrangement direction.
