Solution Overview

Problem

Energy storage containers are oversized due to the large volume of compressor air conditioners used for dehumidification, leading to uneven dehumidification and space inefficiency, and moisture affects battery modules and electrical equipment, reducing their service life.

Innovation Solution

The dehumidifiers are arranged in the gap between the battery clusters and the bottom cover, with their thickness aligned with the height direction of the box body, reducing space occupation and allowing for more efficient battery module arrangement and uniform dehumidification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compressor air conditioners are directly fixed on side plates for dehumidification, then dehumidification function is achieved, but container size becomes oversized and space utilization is reduced

Engineering Contradiction:
Improvedehumidification functionVSAvoidcontainer size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The dehumidifier is rotated 90 degrees and installed in the thickness direction (height direction) within the existing container volume, rather than placing it horizontally on side plates. This dimensional reorientation allows the dehumidifier to fit within the vertical space between battery clusters and bottom cover, eliminating the need to increase container length or width.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The dehumidifier is nested within the vertical space already occupied by battery cluster arrangements. By positioning the dehumidifier in the gap between the bottom of battery clusters and the bottom cover, the design utilizes otherwise wasted vertical space, effectively nesting the dehumidification system within the existing structural envelope.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If compressor air conditioners are directly fixed on side plates, then dehumidification is provided, but dehumidification effect becomes uneven

Engineering Contradiction:
Improvedehumidification functionVSAvoiddehumidification uniformity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

Multiple dehumidifiers are strategically positioned at different locations within the container (e.g., front and rear sections) to create localized dehumidification zones. This distributed arrangement ensures that moisture is removed uniformly throughout the entire container volume, rather than concentrating dehumidification capacity in one location.

Inventive Principle:
Principle #3Local quality

3Reliability

If large volume compressor air conditioners are used, then dehumidification capacity is sufficient, but space for battery modules is reduced

Engineering Contradiction:
Improvedehumidification capacityVSAvoidbattery module space
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The dehumidifier is installed vertically in the thickness direction, utilizing the height dimension that would otherwise be empty space. This orientation allows the dehumidifier to occupy minimal horizontal footprint, preserving maximum space for battery module arrangement while maintaining adequate dehumidification capacity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The dehumidifier is nested within the vertical gap between battery clusters and bottom cover, utilizing space that does not interfere with battery module placement. This nesting approach allows both battery storage and dehumidification functions to coexist within the same vertical envelope without compromising either function.

Inventive Principle:
Principle #7Nested doll (Nesting)
