32-channel formation and grading system for battery packs (0–30 V, ±10 A, 300 W/channel) with energy-feedback discharge, dual closed-loop CC/CV conversion, 16-bit AD/DA high accuracy (±0.05%RD+0.05%FS), rich charge/discharge/pulse/slope modes, powerful SQL/MES data management, and full software/hardware protections for large-scale production testing.
The Semco SI-B BCDS 30V 10A 32CH is a high-integration, 30 V / 10 A, 32-channel formation and cycle test system for battery packs, ideal for formation, grading, performance and life testing in production lines and labs. Each channel delivers up to 300 W with a current range of -10 A to +10 A, minimum current 30 mA, and 16-bit AD/DA measurement for precise control. Voltage and current accuracy reach ±(0.05%RD + 0.05%FS) with 0.1 s sampling, ensuring stable, repeatable test results.
Powered by three-phase AC 380 V (max 12 kW), the system offers power factor ≥0.99 and THD ≤5%, with overall conversion efficiency above 85%. It supports comprehensive charge modes (CC, CV, CCCV, constant power, constant resistance), discharge modes (CC, CP, CR), plus pulse and slope (ramp) charge/discharge, with configurable stop conditions (voltage, current, time, capacity, pulse count, ramp value). Each loop can contain up to 128 steps, with 1–60,000 cycles and step times up to 50×24 hours, making it suitable for long-term aging.
Discharge energy is fed back to the grid, reducing heat and energy cost, while the dual closed-loop CC/CV structure ensures smooth transition without current spikes, protecting cells. Robust hardware protections (reverse connection, short circuit, poor contact, dual-path voltage protection) combine with software protections (power-off/offline data protection, voltage/current/capacity limits, cell-level under/over-voltage and temperature protection) for safe operation.
Data is centrally managed via SQL/MySQL/Access, with Excel/TXT export, full curve plotting (V–t, I–t, capacity–t, capacity–V), barcode scanning, and seamless MES compatibility. Communication uses TCP/IP over RJ45 (10M–1000M) with easy expansion via switches/routers. The system is housed in an IP20 cabinet (approx. 800×600×1300 mm), operates from -10°C to 40°C, noise ≤75 dB, and ships in a wooden case, ready for integration into high-volume battery pack testing and formation lines.
