REC SI-Q Series BMS 16S

Our REC BMS SI/Q series BMS with integrated CAN communication
protocol can manage up to 16 cells in series and supports most cell chemistries. For 16-62V systems

• from 5 to 16 in-series connected cells per unit
• single cell voltage measurement (0.1 – 5.0 V, resolution 1 mV)
• single cell – under/over voltage protection
• single cell internal resistance measurement
• SOC and SOH calculation
• over temperature protection (up to 3 temperature sensors)
• under temperature charging protection
• passive cell balancing up to 0.9 A per cell
• shunt current measurement (resolution 19 mA @ ± 500 A)
• galvanically isolated user defined multi-purpose digital input/output
• reduced 1 s measuring interval
• balancing transistors defect check @ restart
• EEPROM memory data corruption check @ restart
• cell’s voltage RMS voltage measurement
• self calibration @ restart
• BMS shutdown @ 0.98 x minimum cell disconnect threshold
• Ah counting

• galvanically isolated RS-485 communication
• fully compatible with REC LCD touch display and PC user interface BMS Master control

• galvanically isolated CAN
• 100, 125, 250, 500, 1 MHz bit-rate selection
• message programming
