Mobile Energy Storage Rack Layout Without Maintenance Aisles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile energy storage systems require a significant floor space due to the need for a maintenance passage between battery racks and the complexity of wiring and fixing, which increases construction time and costs.
Innovation Solution
The highly integrated mobile energy storage system arranges battery racks back to back, eliminating the need for a maintenance passage, and uses L-shaped fixed adapters for easy fixing and wire holes for simplified wiring, reducing the overall floor space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a maintenance passage with sufficient width is arranged between two rows of battery racks to facilitate maintenance, then the ease of repair is improved, but the floor space of the system increases
Solution Approach 1:
The container is divided into a battery compartment and a device compartment. The two rows of battery racks are arranged back to back in the battery compartment, while maintenance access is provided through the device compartment wall via a maintenance door. This segmentation allows maintenance personnel to access battery racks from the device compartment side without requiring a wide maintenance passage between the battery rack rows, thus reducing the floor space while maintaining ease of repair.
2Ease of operation
If wire holes are arranged in the base of the container to facilitate wiring at the operation place, then the ease of operation is improved, but the construction period increases due to raising the base or deeply tearing up the land
Solution Approach 1:
Wire holes are pre-arranged in the base of the container at factory assembly stage. The wire holes include a first wire hole extending through the base, and second and third wire holes extending through the side walls along the width and length directions respectively. This preliminary arrangement of wiring paths eliminates the need for raising the base or deeply tearing up the land during installation, thus facilitating ease of wiring while reducing construction period.
3Reliability
If the container is fixed by welding foot members and bottom beams with pre-embedded flat steel, then the reliability of fixing is improved, but the difficulty of operation increases due to high demand on tools and operation conditions
Solution Approach 1:
The traditional welding-based fixing system is replaced with a mechanical bolt connection system. L-shaped fixed adapters are used to connect the container to the foundation through bolt connections instead of welding. This substitution eliminates the need for welding machines and pre-embedded flat steel, reducing the demand on special tools and operation conditions while maintaining fixing reliability through the L-shaped adapter structure that provides stable mechanical anchoring.

AI summary
A highly integrated mobile energy storage system is provided, which includes a container and battery racks. The battery racks are arranged in two rows along a length direction of the container, and the two rows of the battery racks are arranged back to back. For each of the two rows of battery racks, a maintenance door is arranged at a wall of the container close to the row of battery racks. In a case that a battery rack needs to be maintained, it is just required to open the maintenance door to maintain the battery rack. Since the two rows of battery racks are arranged back to back, no maintenance passage is required, thereby reducing a floor space along a width direction of the container, thus reducing the floor space of the system.
