Storage Battery Unit Casing Segmentation for Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage battery units are difficult to maintain due to lack of accessibility and design limitations, making maintenance work cumbersome.
Innovation Solution
A storage battery unit design featuring a battery module with a module circuit connected via electric power and communication lines, a unit circuit connected to an external power conversion device, and a casing with tabular components that include a top plate, bottom plate, and lateral plates for easy disassembly and maintenance, allowing for improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a conventional integrated casing design is used, then structural integrity is maintained, but maintenance work becomes difficult and time-consuming
Solution Approach 1:
The casing is divided into multiple separable components: a first casing covering the top surface, a second casing covering the bottom surface, and at least one third casing covering a lateral surface. These segmented casings can be independently removed to access internal components for maintenance, resolving the contradiction between structural integrity and maintenance accessibility.
Solution Approach 2:
The lateral plate (third casing) is extracted as a separate removable component from the integrated casing structure. This extracted component can be easily removed to provide access to the battery module and unit circuit, enabling maintenance work without dismantling the entire casing structure.
2Productivity
If components are easily accessible for maintenance, then operational efficiency improves, but structural protection may be compromised
Solution Approach 1:
The casing is segmented into multiple protective layers (first casing, second casing, third casing) that can be independently opened or closed. When not in maintenance mode, all segments are closed to provide complete structural protection, ensuring reliability. During maintenance, only the necessary segment (third casing) is opened, maintaining protection for other components while enabling access for quick maintenance operations.

AI summary
A storage battery unit includes: a battery module having a plurality of cells, and a module circuit connected to (i) an electric power line and (ii) a communication line; a unit circuit connected to (i) the module circuit by the electric power line and the communication line, and (ii) an electric power conversion device disposed externally; and a casing that accommodates the battery module and the unit circuit. The casing includes a top plate, a bottom plate, and a front plate respectively disposed on a top surface, bottom surface, and front surface of the storage battery unit. The top plate includes a first top plate portion that substantially covers an entirety of the top surface. The front plate includes a first lateral plate portion that substantially covers an entirety of the front surface, and a fixing component. The fixing component is disposed along the first top plate portion.
