Battery Management System
BMS Introduction
Communication Interface
RS485 / RS232 / CAN
Signal Acquisition Function
It has acquisitions of single voltage and external busbar voltage, battery module total voltage,charging/discharging current,surface temperature of battery cell, BMS board temperature for each series.
Battery Cell Equalization Function
The battery has a passive equalization function. When the cell voltage difference exceeds a certain value during charging, the equalization function will be started.
Charging Current Limit Function
It has the ability to automatically enter current-limiting charging when the battery is detected with low voltage, high voltage, low temperature, high temperature, poor consistency, or charging overcurrent protection.
Voltage Acquisition Accuracy
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
System Device Failure Alarm
It has failure detection and alarm function for key components of BMS board. While it is detected with temperature sensor failure, voltage detection failures, charge and discharge MOS failure, 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.
Histroical Storage Function
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.
