==============================================
Works with most cell chemistries and 5-16S Cell packs with a 16-62 VDC range.
REC Q BATTERY MANAGEMENT SYSTEM 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)
