Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery packs, electrical or magnetic noise generated in communication lines connected to batteries is not effectively suppressed by existing technologies.
Innovation Solution
A battery pack design incorporating a support member with electrical or magnetic shielding properties, where the communication line faces the support member along an intersecting direction, effectively reducing noise by blocking or attenuating electromagnetic fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication lines are connected to batteries for control purposes, then battery control functionality is improved, but electrical or magnetic noise is generated
Solution Approach 1:
A shielding member is introduced as an intermediary between the communication line and the batteries. This shielding member acts as a mediator that blocks or redirects electromagnetic fields, preventing noise from reaching the communication line while allowing the communication line to remain connected to the batteries for control functionality.
Solution Approach 2:
The harmful electromagnetic noise is extracted or separated from the communication line by positioning the shielding member in between. The shielding member effectively removes the noise component from the electromagnetic environment, allowing the communication line to function without interference while maintaining its connection to the batteries.
2Object-generated harmful factors
If shielding structures are added to suppress noise, then noise suppression is improved, but device complexity increases
Solution Approach 1:
The shielding member is designed as a thin-walled structure or shell that can effectively block electromagnetic noise without adding significant bulk or complexity. This thin-film approach provides adequate noise suppression while maintaining a simple and compact overall structure.
Solution Approach 2:
The shielding member is designed to perform multiple functions: it provides electromagnetic noise shielding, serves as a structural support element, and can be integrated with existing battery pack components. This multi-functionality reduces the need for additional separate shielding components, thereby limiting the increase in device complexity.

AI summary
A battery pack includes: a plurality of stacked batteries; a support member (an intermediate block) that is adjacent to the batteries along a width direction Y intersecting a stacking direction X of the batteries and supports the batteries; a control member (a control board) that is provided on one end side (a controller unit side) in the width direction Y and controls the plurality of batteries; and a communication line (an electric wire) that is conducted to the control board and extends from the controller unit side toward another end side (a junction unit side) facing the controller unit side along the width direction Y. The intermediate block has an electrical or magnetic shielding property. The electric wire faces the intermediate block in a region from the controller unit side to the junction unit side.
