DEGSON Flexible Copper Busbar Energy Storage Connectors for C&I Energy Storage Projects
DEGSON Flexible Copper Busbar Energy Storage Connectors for C&I Energy Storage Projects
Project Background
A manufacturing enterprise constructed a commercial and industrial distributed energy storage system to ease peak power demand and cut electricity expenses. The system adopts air-cooled PACK modules with limited installation space. The project requires efficient connections between battery modules, busbars and BMS high-voltage boxes, as well as superior safety performance to withstand harsh industrial operating conditions.
Customer Pain Points
1. The confined interior of air-cooled PACKs makes traditional rigid wiring inflexible. It cannot compensate for angular deviations and thermal expansion & contraction between modules, which easily causes loose connections.
2. Standard connectors lack anti-misplug and anti-accidental-disassembly structures, bringing high-voltage safety risks. Their complicated assembly fails to meet the demand for rapid construction in industrial projects.
3. The customer required an integrated customized solution to reduce intermediate transfer links and minimize potential failure points.
Solution
DEGSON customized the S-ESPP-250A flexible copper busbar integrated energy storage connector solution for this project, paired with dedicated S-ESPP-250A-B70 low-protection connectors for air-cooled systems and tailor-made flexible copper busbars. It perfectly matches the working conditions of commercial & industrial air-cooled energy storage PACKs and delivers one-stop integrated supply of "connectors + flexible copper busbars".
Five Core Advantages of the Solution
1. Space Optimization to Improve PACK Energy Density
The S-ESPP series features a compact snap-lock release design. Matched with flexible copper busbars, it adapts to narrow inner spaces and irregular wiring paths inside PACKs. It automatically offsets assembly tolerances and absorbs thermal expansion and contraction to eliminate loose connections, tidy internal wiring and boost PACK space utilization by 20%.
2. Multi-Layer Safety Protection to Eliminate All High-Voltage Hazards
The connectors integrate polarity anti-misplug and secondary lock anti-disassembly functions. The socket provides full touch protection when unmated. All components are made of UL94 V-0 flame-retardant material. Equipped with an MSD manual service disconnect switch, it rapidly cuts off high-voltage circuits during maintenance to avoid operational risks, fully securing system operation.
3. Fast Assembly to Greatly Shorten Construction Cycles
Factory standardized pre-crimping technology and snap-in plug-and-play design lower operation thresholds. Compared with traditional rigid connection schemes, assembly efficiency rises by 60%, significantly shortening on-site construction time.
4. Customized Integrated Design to Reduce Failure Points
Flexible copper busbars are customized in length, hole positions, bending angles and insulation coating according to the customer’s PACK dimensions and current requirements. Perfect matching between connectors and busbars removes intermediate transition parts, cuts failure risks and enhances overall system reliability.
5. Complete International Certifications to Meet Commercial & Industrial Compliance Standards
The full solution has passed authoritative domestic and international certifications including UL, TUV and CE, fully complying with safety and electrical compliance criteria for commercial & industrial energy storage equipment.
Project Results
After commissioning, DEGSON’s integrated connection solution has operated stably without any connection-related failures:
• PACK internal space utilization increased by 20%;
• Overall installation cycle shortened by 30%;
• Annual electricity and maintenance costs reduced by approximately 200,000 RMB for the enterprise;
• Stable peak shaving and load balancing ensure continuous and reliable power supply for factory production.
Now this integrated solution has been widely deployed in manufacturing plants, commercial complexes and other commercial & industrial energy storage projects, serving as a benchmark flexible high-voltage connection scheme for air-cooled PACKs.
