| Information sampling function | With each series-connected single cell voltage,extemal busbar voltage,total battery pack voltage,charging and discharging current,cell surface temperature,BMS single-board temperature sampling function |
| Battery Cell equalization function | The battery has a passive equalization function,which can be activated when the cell pressure difference exceeds a certain value during charging. |
| Charging current Limit function | With the function of automatically entering the current-limiting charging mode when detecting the battery cell:low voltage,high voltage,low temperature,high temperature,poor consistency charging over-current protection |
| Voltage acquisition accuracy | 0~5V,Detection accuracy≤10mV;0~60V Detection accuracy≤0.5% |
| Current acquisition accuracy | Detection accuracy≤1%(0.5C charging/discharging) |
| Anti-theft function | Software anti-theft,communication anti-theft,gyroscope anti-theft and other functions are optional |
| System component failure alarm | It has failure detection and al arm function for key components of BMS board.Whileit is detected with temperature sensor failure,voltage detection failures,charge and discharge MOSfailure,an alarm will be generated and the charge and discharge loops will be disconnected (if the charge and discharge loop is damaged,it is not required to disconnect) the battery cannot recover automatically,and all the indicators flash to prompt |
| History logs | 500 historical records,10000 historical records and life-cycle storage are optional;Independent storage space;BMS has power failure preservation capability;Historical data records include battery voltage,current,ambient temperature,SOC,SOH,cycle times,cumulative discharge capacity and other data |
