As energy storage systems, electric vehicles, power equipment, and charging infrastructure expand worldwide, the demand for sheet metal fabrication in new energy equipment continues to rise. From battery cabinets and inverter enclosures to EV charging stations and Battery Exchange Cabinet systems, structural components not only provide mechanical support and protection but also need to meet heat dissipation, waterproofing, and fire safety standards. This article explores the main applications of sheet metal structures in new energy equipment, industry trends, and future opportunities.
1. Energy Storage Systems: The Fastest-Growing Sheet Metal Application
Energy storage systems (BESS) have become one of the fastest-growing segments in the global new energy industry. Core structural components are mostly manufactured from sheet metal, including:
- Battery Cabinets
- Energy Storage Enclosures
- PCS Inverter Cabinets
- Energy Storage Container Structures
- Battery Module Racks
These structures support the equipment while ensuring heat dissipation, fire resistance, dust and water protection. According to Research and Markets, the global market for battery enclosures and cabinets is expected to reach USD 1.32 billion in 2026 and grow to approximately USD 1.98 billion by 2032, at a compound annual growth rate of 6.8%. As grid-scale and commercial energy storage projects increase, the demand for structural components continues to rise.
2. Solar and Renewable Power Equipment Driving Cabinet Demand
Renewable energy generation equipment also requires significant sheet metal structures. Typical applications include:
- Solar Inverter Enclosures
- Integrated PV Energy Storage Enclosures
- Wind Power Control Cabinets
- Electrical Distribution Cabinets
These devices operate outdoors, requiring high IP protection, corrosion resistance, thermal management, and vibration-proof design. Global market data shows the inverter cabinet market was approximately USD 392 million in 2024 and is expected to grow to USD 529 million by 2031, driven by the expansion of PV and renewable energy installations.
The market for electrical cabinets in renewable power systems continues to grow steadily and is expected to maintain stable growth in the coming years.
3. Electric Vehicle Battery Structures
Electric vehicles are another major application area for sheet metal components. The battery system is one of the most critical parts of an EV, and battery pack enclosures are typically high-strength metal structures providing support and safety. Typical components include:
- Battery Pack Enclosures
- Battery Trays
- Battery Protection Structures
- Electronic Control System Enclosures
These components require mechanical strength, collision safety, waterproofing, and thermal management. Automotive applications account for more than 35% of the global battery enclosure market, making it one of the largest use cases. Common structural materials include high-strength steel, aluminum sheet metal, and lightweight composites. Achieving lightweight design while ensuring safety and thermal efficiency is a key focus in EV battery structure design.
4. Charging and Battery Exchange Infrastructure
As EV adoption grows globally, both traditional charging and Battery Exchange Cabinet systems are becoming essential infrastructure. These devices rely on metal enclosures and structural components for housing and support. Some modern charging stations also integrate intelligent storage solutions, such as Smart Locker systems, to manage battery modules or auxiliary equipment efficiently.
Typical equipment includes:
EV charging stations: DC fast-charging cabinets, AC charging station enclosures, power control cabinets, power module housings
Battery Exchange Cabinet systems: battery swap cabinets, storage cabinets, automated battery exchange frames
These components operate in demanding environments and require high strength, durability, waterproofing, corrosion resistance, and efficient heat dissipation. As global charging and battery swapping networks expand, demand for related sheet metal structures continues to grow.
5. Trends in New Energy Equipment Structure Design
With the increasing scale of new energy equipment, structural design is evolving along three main trends:
Modular Design: Standardized battery cabinets and modular energy storage enclosures reduce transportation, installation, and maintenance costs, enabling scalable manufacturing.
Higher Safety and Protection Standards: Rising power density drives higher safety requirements, including fireproof and explosion-resistant designs and enhanced protection levels.
Automated Manufacturing: Rapid market growth encourages manufacturers to adopt robotic welding, automated bending, and smart quality inspection systems to improve production efficiency and consistency.
6. The New Energy Industry Driving Manufacturing Upgrades
The new energy industry is expected to maintain high growth, with energy storage systems, power equipment, and charging infrastructure driving ongoing demand for structural components and equipment cabinets. Sheet metal fabrication is no longer just an enclosure manufacturing step; it is becoming a critical factor for the safety, stability, and reliability of new energy equipment. As modular designs and advanced manufacturing technologies continue to evolve, the growth of the new energy sector offers significant opportunities for the sheet metal fabrication industry.
