Bess Container Assembly Line Solution

Bess Container Assembly Line Key Features

• Comprehensive automation—from cabin lifting and inspection to final PACK installation and liquid-cooling system integration, enabled by PLC/HMI control, robotics-assisted handling, and reliable fault-detection mechanisms.
• Liquid cooling integration—installation of cooling pipes and liquid chiller connections with validated leak-tightness and pressure-hold testing to ensure thermal performance and system safety.
• End-to-end assembly workflow—includes interior box cleaning, busbar harness laying, MC cabinet installation, PACK insertion, high-voltage components integration, and routing of service lines.
• System-level verification—safety regulation testing, fire protection testing, and airtightness testing to satisfy strict industry and grid-application requirements.
• Electrical & fluid interfaces—precise system liquid filling, unit function testing, and comprehensive End-of-Line (EOL) testing, followed by packaging and off-line handling based on customer process requirements.
• Customization capability—the line is adaptable to specific process requirements, enabling configuration changes without major retooling for different PACK specifications.
• Data-driven quality and traceability—process data captured via MES, test results and welding parameters stored for traceability and continuous improvement.

Process Modules and Capabilities

• Cabin handling—handling and inspection of cabins to ensure accessibility and alignment for downstream assembly steps.
• Liquid cooling subsystem—installation and routing of liquid cooling pipes, integration with chiller units, and associated plumbing tests.
• Pipeline and pressure management—pipeline pressure holding tests and leakage checks for fluid systems.
• Interior cleaning and preparation—cleaning the interior of the PACK housing to ensure optimal bonding and assembly quality.
• Electrical harnessing—busbar harness laying, cable routing, and connector termination with controlled tension and routing verification.
• Electrical cabinet assembly—installation of MC cabinets and high-voltage interconnects with proper shielding and safety interlocks.
• PACK installation—precise placement and securing of PACK modules, alignment verification, and pre-load checks.
• High-voltage & safety assemblies—integration of high-voltage boxes, insulation checks, and compliance with safety standards.
• Cooling system integration—connectivity of cooling circuits to PACKs, validation of flow paths and temperature control behavior.
• System verification—safety regulation testing, fire protection testing, airtightness testing, and functional system tests.
• Fluid management—systematic liquid filling procedures and verification of liquid levels, concentrations, and return paths where applicable.
• Testing & validation—unit function testing, End-of-Line (EOL) testing, and charge/discharge testing to validate battery performance and safety margins.
• Packaging & off-line handling—final packaging, labeling, and safe off-line transport preparation tailored to customer requirements.
