Modular Battery Platform for Adjustable Energy Storage Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional energy storage systems have a fixed capacity, making it difficult and cumbersome to increase capacity to meet changing load demands, as they require direct connection of additional batteries to the power line, which is complex and inefficient.
Innovation Solution
An energy storage apparatus that allows for adjustable capacity by stacking battery platforms and trays, where connectors on each unit couple in series, enabling easy expansion and management of energy storage capacity without direct connection to power lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a new energy storage system is installed to increase capacity, then the energy storage capacity is increased, but the device complexity and installation difficulty increase
Solution Approach 1:
The energy storage system is divided into modular units (battery modules) that can be independently installed and connected. Each module contains standardized connectors and control units, allowing the system to be segmented into manageable sections that can be assembled in sequence without requiring complete system disassembly or complex wiring modifications.
Solution Approach 2:
Battery modules are designed with nested structural relationships where smaller battery cells are arranged within standardized module housings, which themselves can be stacked or connected to form larger energy storage systems. This nested architecture allows capacity expansion by simply adding more modules in a hierarchical structure.
2Quantity of substance
If a separate battery is connected to an existing energy storage system to increase capacity, then the energy storage capacity is increased, but the connection difficulty and operational complexity increase
Solution Approach 1:
The battery modules employ universal standardized connectors and interface protocols that can be used across different module configurations and system capacities. The same connector type and control interface are used whether connecting one module or multiple modules, eliminating the need for specialized connection procedures when expanding system capacity.
Solution Approach 2:
Multiple battery modules are merged into a unified control system through standardized communication interfaces. The control units of individual modules can be electrically connected in series or parallel configurations, allowing multiple independent battery units to function as a single integrated energy storage system with shared monitoring and control capabilities.
3Device complexity
If traditional energy storage systems are used with fixed capacity, then the system structure is simple, but the adaptability to changing load demands is poor
Solution Approach 1:
The energy storage system transitions from a fixed static configuration to a dynamic reconfigurable architecture. Battery modules can be dynamically added, removed, or reconfigured between series and parallel connections based on real-time load demands and system requirements, allowing the system capacity and voltage/current characteristics to adapt flexibly without fundamental structural changes.
