Solution Overview
Problem
Large-scale energy storage systems are bulky, heavy, difficult to transport, and inconvenient to assemble, and are typically designed for a single application, making them inflexible for adapting to different uses.
Innovation Solution
A battery system comprising a first battery module with a battery management system and first battery cells, and a plurality of second battery modules with more battery cells but no management system, allowing for modular design with same-sized housings to achieve varying voltage capacities, enabling easy transport and assembly, and integration into large-scale systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large-scale energy storage systems are designed with high voltage capacity, then power supply capability is improved, but the system becomes bulky and heavy
Solution Approach 1:
The battery system is divided into multiple modular units, each containing a manageable number of battery cells (e.g., 9-11 cells per module). These modules can be combined in series to achieve high voltage capacity while keeping each individual module lightweight and compact, thus resolving the contradiction between power supply capability and system weight.
2Power
If large-scale energy storage systems are designed with high voltage capacity, then power supply capability is improved, but the system becomes difficult to transport
Solution Approach 1:
By segmenting the battery system into standardized modular units with compact dimensions, each module becomes easy to transport individually. The modular design allows flexible configuration to achieve high voltage capacity without requiring transport of a single large, cumbersome system.
Solution Approach 2:
The modular battery modules are designed with nested or stackable configurations that optimize space utilization during transport. Multiple modules can be arranged efficiently within container spaces or transport vehicles, maintaining compact form factor while achieving high overall voltage capacity through modular assembly.
3Power
If large-scale energy storage systems are designed for single application, then voltage capacity specification is fixed, but the system becomes inflexible for adapting to other uses
Solution Approach 1:
The standardized modular battery modules are designed with universal interfaces and configurations that can be adapted to multiple applications. By varying the number and arrangement of modules, the same basic module design can serve different voltage and capacity requirements across diverse applications, achieving both fixed voltage specification and application flexibility.
Solution Approach 2:
The modular architecture enables dynamic reconfiguration of the battery system. Modules can be added, removed, or rearranged to adapt to different application requirements, transforming a static single-purpose system into a dynamic multi-purpose platform that maintains optimal voltage capacity specification for each specific application.
4Volume of stationary object
If large-scale energy storage systems are assembled in container-type configurations, then space utilization is improved, but the system becomes inconvenient and dangerous to assemble
Solution Approach 1:
The container-type space is filled with standardized modular battery units that are pre-assembled with integrated management systems. Each module is a self-contained unit that can be easily handled and assembled by standard procedures, making the overall assembly process convenient and safe while achieving optimal space utilization through systematic arrangement of modules within the container.
