External-Access Battery Container Layout for Higher Energy Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems have low energy density due to internal maintenance channels that occupy space, and pose safety risks for maintenance personnel due to the chemical instability of lithium-ion batteries.
Innovation Solution
A container-type energy storage system with external maintenance access, eliminating the need for internal maintenance channels by using compartment doors for external access to battery clusters, thereby increasing usable space and improving safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an internal maintenance channel is arranged inside the container, then maintenance personnel can enter to maintain energy storage equipment, but it occupies space inside the container resulting in low overall energy density
Solution Approach 1:
The maintenance channel is extracted from the internal space of the container and relocated to the external side. The container wall is designed with an openable structure that allows maintenance personnel to access the interior from outside, eliminating the need for internal maintenance channels and recovering the occupied space for energy storage battery arrangement.
2Ease of repair
If the maintenance channel is arranged inside the container, then maintenance can be performed, but the limited internal space makes the channel small and inconvenient for large maintenance equipment
Solution Approach 1:
The maintenance channel function is extracted from the container interior and implemented through an external access opening in the container wall. This allows maintenance personnel and equipment to approach from outside, utilizing the external environment rather than constrained internal space for maintenance operations.
3Ease of repair
If maintenance is performed inside the container, then energy storage equipment can be maintained, but lithium-ion batteries cause chemical instability dangers to maintenance personnel
Solution Approach 1:
The maintenance access function is extracted from the container interior and relocated to the exterior. The container wall incorporates an openable structure that enables maintenance personnel to access energy storage equipment from outside, eliminating exposure to harmful chemical emissions from lithium-ion batteries during maintenance operations.
4Ease of operation
If internal maintenance channels are used, then maintenance can be accessed, but the container space is reduced resulting in low overall energy density
Solution Approach 1:
The maintenance channel is extracted from the container's internal volume and repositioned to the external surface. The container wall is designed with an openable maintenance access that allows personnel to enter from outside, completely eliminating the need for internal maintenance corridors and maximizing the container's energy storage capacity.
