Battery Module End Plate Recess for Coupling Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules increase in size due to the mounting of battery monitoring units, which affects their compactness and efficiency.
Innovation Solution
A battery module design that incorporates a battery monitoring unit with a coupling connector accommodated in a recess of the end plates, allowing the connector to be positioned between the recess and the substrate, thereby reducing the module's height and preventing size increase.

1Reliability
If a battery monitoring unit with a coupling connector is mounted on the battery cell assembly, then the battery monitoring function is achieved, but the battery module increases in size
Solution Approach 1:
The coupling connector is nested within the recess of the end plate, allowing the connector to be housed inside the existing structure rather than protruding outward. This nesting approach enables the battery monitoring unit to be integrated into the battery module without increasing its external dimensions, as the connector is accommodated within the recess space that is part of the end plate's existing geometry
2Ease of operation
If the coupling connector is positioned on the battery cell assembly side, then the battery monitoring unit can be mounted, but the module height increases
Solution Approach 1:
Instead of positioning the coupling connector in a way that increases height in the vertical dimension, the recess provides accommodation in the lateral dimension. The recess is formed in the end plate such that the connector can be housed within it, shifting the space utilization from the height direction to the width/depth directions of the end plate structure

AI summary
A pair of end plates is a pair of members provided at both ends of a battery cell assembly in an array direction to clamp the battery cell assembly from both sides in the array direction. The pair of end plates has a plate upper surface and a recess. The plate upper surface is positioned on the same side as that of an electrode mounting surface. The recess is recessed from the plate upper surface and accommodates at least part of a coupling connector. With this configuration, a battery module and a battery monitoring unit mounting structure can prevent the battery module from increasing in size.
