Storage Battery Block Rotation for Project-Life Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage batteries with shorter useful lives than the project life of the battery system necessitate frequent replacement, leading to waste of resources and increased disposal costs, as well as environmental impact, due to the removal of batteries with remaining life.
Innovation Solution
A storage battery system is divided into blocks, with one block rested and the others operated in rotation, ensuring the total capacity meets project requirements and preventing the sum of actual and equivalent degradation from exceeding the project life, thereby extending the system's usable life.

Engineering Contradiction Analysis
1Duration of action of stationary object
If storage batteries are replaced before the end of their useful lives to match the project life, then the storage battery system can be used over the project life, but storage batteries having long remaining lives are forced to be removed and disposed of
Solution Approach 1:
The storage battery system is divided into multiple storage battery blocks (e.g., 5 blocks). Each block contains multiple storage batteries. This segmentation allows the system to rotate which blocks are operational and which are resting, preventing the need to dispose of batteries with remaining life while ensuring the system meets project life requirements.
Solution Approach 2:
The system implements periodic rotation between operational and resting states for different storage battery blocks. Each block cycles through operational periods followed by resting periods. This periodic action ensures that no single block is overused, allowing the system to maintain operation for the full project life while preserving individual battery life.
2Productivity
If storage batteries are operated continuously to meet project capacity requirements, then the system maintains required performance, but the useful life of individual batteries is shortened
Solution Approach 1:
By dividing the system into multiple blocks, the total capacity requirement is distributed across operational blocks while resting blocks preserve battery life. The sum of capacities of operational blocks meets or exceeds the required project capacity, while rotation ensures individual battery longevity.
Solution Approach 2:
The systematic rotation between operational and resting states provides periodic relief to individual battery blocks. This periodic rest allows batteries to recover and extend their useful life, while the system maintains continuous operational capacity through multiple blocks.
3Reliability
If all storage batteries are replaced every time the end of their useful lives arrives, then individual battery life is respected, but disposal costs increase and resources are wasted
Solution Approach 1:
The system proactively rotates battery blocks into resting states before their useful lives are fully exhausted. This preliminary action prevents the need for disposal by ensuring batteries are taken out of service while still having remaining life, thereby avoiding disposal costs and resource waste.
Solution Approach 2:
Instead of discarding batteries at the end of their useful lives, the system recovers them by rotating them into resting states where they can be preserved and potentially reused. This approach transforms what would be discarded resources into available assets.

AI summary
A plurality of storage batteries are divided into a plurality of storage battery blocks. A useful life of each of the storage batteries is shorter than the project life. Total capacity of the plurality of storage batteries is equal to or greater than the product of capacity required for a project and a ratio of the project life to the useful life. The project life is divided into a plurality of periods. For each of the plurality of periods, a rest storage battery block is selected from the plurality of storage battery blocks in rotation, the rest storage battery block is rested, and an operational storage battery block is operated. The sum of actual operating time of each of the storage battery blocks and equivalent operating time of each of the storage battery blocks is prevented from exceeding the useful life during the project life.
