ESS is a system that enhances power efficiency by saving energy in the storage device while power consumption is low, and supplying it when demand is high. The ESS industry is forecast to show high growth as it is supported by government and prices of batteries will be lower. As secondary battery manufacturers enter the ESS market, the demand for ESS battery electronic products using secondary batteries is increasing. Based on our eco-friendly car battery pack electronic product development technology, we are supplying ESS electronic products, harness modules for battery modules, and connectivity modules for connection among modules.
Types and purposes
• BPU (Battery Protection Unit): Electronic box
Basically mounted with a BMS, the BPU protects rack units, converts charging/discharging modes, and transmits signals through voltage/current performance monitoring.
• Battery pack harness module
Various structures within the cable assembly pack for power withdrawal, and movement signal monitoring Modularizes and supplies terminal blocks, fuses, and inter connection boards
• External connectivity (Rack harness)
The best assembly construction for connection between battery packs and electronic boxes
Benefits
• Customized BPU for Battery Pack system
• Compact size, enables system construction according to standard rack specification
• Minimizes faults and secures assembly by modularizing inner harness
• Adopts optimized cable and connector components according to system requirements
• Maximizes assembly through various structures and modules for the battery module
• Selects connectivity layout according to system configuration and assembly (F. busbar, Cable, Busbar, etc.)
