REC Q BATTERY MANAGEMENT SYSTEM 16S
Our REC BMS Q series with integrated CAN communication
protocol can manage up to 16 cells in series.


REC Q BMS:
- 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

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

Galvanically Isolated CAN:
- galvanically isolated CAN
- 100, 125, 250, 500, 1 MHz bit-rate selection
- message programming
- disable option
