According to information from the China National Intellectual Property Administration, Schneider Electric Industries SAS has been granted a utility model patent titled “Integrated Switch and Energy Storage High-Voltage Box Including the Same” (Grant Publication No. CN224053939U), filed on December 2024.
The invention introduces an integrated switching architecture designed for use in energy storage high-voltage battery cabinets, aiming to improve system integration, reduce wiring complexity, and enhance overall reliability and thermal performance.
Overview of the Invention
The patented solution describes an integrated switch module deployed within an energy storage high-voltage box. The system primarily includes:
Input/output interfaces, configured to receive control signals and transmit feedback signals
Multiple switching units, responsible for executing connection or disconnection operations between battery clusters and power conversion systems (PCS) based on control signals
A feedback mechanism that reports the operational status of switching actions
Through this architecture, the system enables coordinated control of battery strings and energy storage converters within a unified switching framework.
Key Technical Innovation
The core innovation lies in the functional integration of multiple control and switching circuits into a single unified switch module, significantly reducing the need for extensive external wiring inside the high-voltage enclosure.
By embedding control logic and switching functions directly into the integrated switch unit, the system achieves:
1. Reduced Wiring Complexity
The number of internal wiring harnesses required in the energy storage high-voltage box is significantly reduced, simplifying system design and installation.
2. Lower Thermal Load and Improved Safety
Reduced wiring density helps decrease internal heat accumulation, improving thermal management performance and enhancing overall system safety and stability.
3. Easier Installation and Maintenance
With fewer wiring connections and simplified architecture, system assembly becomes easier, while maintenance and troubleshooting are more straightforward.
4. Higher System Reliability
Integration of control and switching functions reduces potential failure points associated with complex wiring networks, improving overall operational reliability.
Application Scenario: Energy Storage High-Voltage Systems
The invention is particularly applicable to battery energy storage systems (BESS), where high-voltage battery cabinets interface with power conversion systems in grid-scale or industrial energy storage applications.
In such systems, wiring complexity and thermal management are critical challenges due to:
High current density
Dense electrical architecture
Long-term continuous operation requirements
Safety constraints in confined enclosures
The integrated switch design directly addresses these challenges by simplifying internal architecture while improving system-level efficiency.
Industry Significance
This patent reflects a broader trend in energy storage system engineering:
From Discrete Components → Highly Integrated Electrical Architectures
Key implications include:
Improved compactness of energy storage cabinets
Reduced assembly and commissioning complexity
Enhanced thermal stability in high-density designs
Greater suitability for modular and scalable energy storage deployments
As battery energy storage systems continue to scale globally, especially in grid stabilization, renewable integration, and industrial backup applications, integration-level innovations such as this play a critical role in improving system performance and reducing lifecycle cost.
Conclusion
Schneider Electric’s integrated switch patent demonstrates a clear shift toward highly integrated, thermally optimized, and maintenance-friendly energy storage architectures.
By reducing wiring complexity while consolidating control and switching functions, the innovation enhances both engineering efficiency and operational reliability, supporting the continued evolution of next-generation energy storage infrastructure.
