Client: Confidential | Industry: Energy Storage & Utility Scope: 3D Engineering Model, HVAC Integration & CFD-Based Thermal Analysis Discipline: Electrical Engineering | Mechanical (HVAC) | Energy Storage 

🧱 Project Overview 

ECF Engineering Consultants was engaged to develop a detailed three-dimensional model and thermal performance analysis of a 42-rack battery bank container system, supporting the next generation of Battery Energy Storage Systems (BESS). 

The objective was to evaluate spatial coordination, heat generation, and HVAC capacity requirements to ensure reliable performance under real-world discharge conditions. The work was informed by performance data from Hyosung’s CFD Battery Container report and a technical evaluation worksheet produced by ECF. 

🔧 Scope of Work 

🧊 3D Spatial & HVAC Integration Modeling 

• Constructed a full 3D model of the 42-rack battery container system, including: 

  • Accurate battery rack spacing based on OEM specifications 

  • Structural envelope and service clearances 

  • HVAC layout integration for forced-air thermal regulation 

    
    

🔥 Thermal Load Analysis 

• Modeled operational discharge performance at a 2-hour rate, consistent with application demands for grid support or peak-shaving functions. 

• Evaluated internal heat gain based on real-time electrical load and battery chemistry parameters. 

• HVAC system design was sized to manage heat dissipation during peak load cycles, using results from computational fluid dynamics (CFD) simulations. 

📊 Reporting & Engineering Deliverables 

• Delivered a summary engineering report presenting: 

• Modeled thermal performance 

• Estimated equipment heat losses 

• Recommendations for HVAC performance optimization 

• Spatial layout validation for fabrication or field installation
