Industrial Semco SI-Y BMST 1–6S system for fast, precise testing of lithium battery protection boards. Supports 1–6 strings, overcharge/overdischarge, recovery voltage, delay, overcurrent, equalization, self-consumption and internal resistance. ±1 mV programmable 0.5–5 V output, up to 120 A current test, barcode start, data logging and Excel reports for production, IQC, QC and R&D.
The Semco SI-Y BMST 1–6S (60A/120A) is a dedicated protection board safety and function tester designed for 1–6-series lithium battery BMS/protection PCBs. It verifies whether protection parameters stay within defined limits, giving production, incoming inspection and R&D teams a standardised, repeatable test platform to improve yield and quality control. The system is compatible with positive/negative split-port boards, same-port designs, charge-protect/discharge-protect architectures and supports ternary, LFP, LCO, LMO and other lithium chemistries.
Multiple test modes cover the full workflow:
Rapid Test for high-throughput shipment/line testing using upper/lower design limits.
PBTS(M) Mode to analyse delay behaviour at configurable speeds.
Accurate Test with ±1 mV precision for exact parameter debugging and R&D.
Laboratory Mode to independently program each cell from 0.5–5 V, simulate charge/discharge and view per-string operating current, enabling equalisation, OV/UV and MOS on/off analysis.
Core test items include internal resistance, individual OV/UV and recovery voltages, OC/OD delay, charge/discharge protection current, over-current delay, secondary OC/OD delay, equalisation current/voltage and true per-cell self-consumption. High-current tests are handled by a 120 A module with ±0.1 A accuracy, and a programmable voltage module (0.5–5 V, ±1 mV).
Data is captured via USB–RS232 to the upper-computer software, which has independent IP and stores all results as Excel for full traceability. It supports barcode auto-start/manual start, pass/fail judgement based on user specs, and C++/C# DLLs for secondary development and custom automated test flows or lab calibration routines. Compact 430 × 420 × 190 mm, ~13 kg chassis makes it easy to integrate on benches or in production cells (max 600 W only at high current tests).
