Partitioned Battery Pack Layout for Higher Space Utilization

Solution Overview

Problem

Battery packs have a low inner space utilization rate, leading to low grouping efficiency.

Innovation Solution

A partition assembly divides the sealed cavity of the battery pack into multiple independent mounting cavities, with electrode assemblies and electrolyte placed within these cavities to fully utilize the space, increasing the energy density.

VSEngineering Contradiction Analysis

1Device complexity

If the battery pack uses a conventional single-cavity structure, then the structure is simple, but the inner space utilization rate is low

Engineering Contradiction:

Improvestructure simplicityVSAvoidinner space utilization rate

Core Design Contradiction:

Device complexityVSVolume of moving object

Solution Approach 1:

The sealed cavity is divided into multiple independent mounting cavities using partition assemblies, allowing each cavity to be independently filled with electrolyte and accommodate electrode assemblies. This segmentation increases the inner space utilization rate by eliminating wasted space between electrode assemblies while maintaining a relatively simple overall box structure.
