As Base Energy Storage (BESS) projects become increasingly complex with higher energy densities and more stringent technical requirements, the use of modified standard ISO containers has revealed many limitations. To truly optimize performance, ensure safety and maximize return on investment (ROI), leading system integrators and developers are turning to OEM/ODM BESS container shell solutions. This is not just a trend, but an inevitable step forward to meet the challenges of the industry.
Why is custom machining superior?
Choosing custom manufacturing over a standard solution offers strategic benefits that cannot be overlooked.
1. Design optimizes space and operating performance
Instead of trying to fit equipment into an existing space, the best option is to manufacture BESS containers with optimized designs from the start.
- Maximize energy density: Arrange battery racks scientifically to contain the most energy in a given space.
- Optimize airflow: Precisely design the cooling system and vents to ensure efficient airflow, eliminating “hot spots” that can reduce battery life.
- Enhanced maintainability: Arrange aisles, doors and access points reasonably, making it easy for technical staff to check, maintain and replace equipment without encountering obstacles.
2. Integrated active and comprehensive safety system
Safety is a non-negotiable priority in BESS projects. Custom-engineered containers allow safety systems to be deeply integrated into the design phase, rather than being an add-on.
- Specialized fire protection system: Integrating the most advanced fire suppression systems such as clean gas (Heptafluoropropane), water mist systems, or Aerosol, precisely positioned at the highest risk locations to extinguish incidents as soon as they arise.
- Active thermal management: Design the HVAC or liquid cooling system with a capacity suitable for the amount of heat emitted from the battery system, ensuring the battery always operates within a safe temperature range, preventing the risk of thermal runaway.
- Resistant and protective structure: The housing is reinforced to withstand the heavy load of the battery packs and meets the seismic standards at the installation site. At the same time, tightness standards such as IP54 or IP55 will be guaranteed to protect the device from dust and water.
3. Specialized materials and coatings for every environment
Each installation site has its own environmental conditions, a customized solution will allow the investor to choose the most suitable materials and coatings.
- Corrosion resistance level C5: For coastal projects or in industrial zones with chemicals, the container shell for the BESS system can be treated with a multi-layer paint system that meets C5 anti-corrosion standards, ensuring decades of durability against termites and high humidity.
- Wide range of materials: In addition to standard corten steel, other materials can be selected according to project requirements to optimize weight or other technical properties.
