Connection Module Vertical Routing for Power Storage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection modules for power storage element groups occupy a larger area as the number of power storage elements increases, particularly when more detection lines are required, limiting their placement on vehicles with exhaust ducts or similar constraints.
Innovation Solution
A connection module design featuring an insulating protector with a vertical extension and a flexible printed circuit with a bent part that reduces the occupied area without compromising wiring space, allowing for adjustable configuration to accommodate increasing numbers of power storage elements and efficient attachment.

1Measurement precision
If the number of power storage elements is increased and more detection lines are provided, then the detection capability is improved, but the occupied area on the upper surface of the power storage element group increases
Solution Approach 1:
The flexible printed circuit is configured to extend in the vertical direction from the upper surface of the power storage element group, utilizing the third dimension (height) rather than only the horizontal plane. This allows detection lines to be routed vertically along the side surface, reducing the occupied area on the upper surface while maintaining adequate wiring space for enhanced detection capability.

AI summary
A connection module includes: an insulating protector that holds a plurality of bus bars to connect between electrode terminals; and a flexible printed circuit that is held by the insulating protector, and includes a detection line that is connected to the each of the bus bars and detects a state of the power storage element. The insulating protector includes a protector horizontal part including a holding part which holds each of the bus bars and is formed at one end; and a vertical part that is extended in a vertical direction from the protector horizontal part in at least a part of another end, opposite to the one end, of the protector horizontal part. The flexible printed circuit includes: a substrate horizontal part that is held by the protector horizontal part; and a bent part that is bent perpendicularly to the substrate horizontal part and held by the vertical part.
