3.3 Battery management system (BMS)
3.3.1 Voltage protection
•Over-charge protection and recovery
During charging, if the voltage of any cell exceeds the setting for cell protection or total
voltage of the system is greater than the setting for the system, the BMS stop charging.
And when all voltage of each cell and total voltage of the battery drop to the recovering-
set values, the protection removes automatically. The voltage settings are shown as No. 1,

ASTERION RTL battery system manual
12
2 in table 3.8.
•Over-discharge protection and recovery
During discharge, if the voltage of any one cell or total voltage of the battery is lower than
the protection settings, the BMS stops discharge. And when all cell voltage and total
voltage go up to recovering-setting, the protection removeautomatically. The settings are
shown as No. 3, 4 in table 3.8.
3.3.2 CURRENT PROTECTION
•Charging over-current protection and recovery
When the charging current bigger than the charging over-current protection current
value andmore than the delay time of charging over-current protection, the system would
enter the mode of charging over-current protection and turn off the charging MOS. The
system would recover from the protection of the charging over-current in every 60
seconds. The settings are shown as No. 6, 7 in table 3.8.
•Charging current limit
During charging, if the charging current is greater than the setting value, the BMS will limit
the charging current to less than the setting value.
•Discharging over-current protection and recovery
When the discharging current beyond the charging over-current protection current and
more than the delay time of discharging over-current protection, the system would enter
the mode of discharging over-current protection and turn off the discharging MOS. The
system would recover from the protection of the discharging over-current in every 60
seconds. The settings are shown as No. 9, 10 in table 3.8.
•Short circuit protection and recovery
When the discharging current beyond the value of short circuit protection and reaches
the delay time of the short circuit protection, the system would enter the mode of short
circuit protection and turn off the discharge MOS. The system wouldn’t recover by itself
unless remove the load or charge the battery. The settings are shown as No. 11 in table 3.8.
•Reverse polarity protection and recovery
When the battery and rectifier are in reserve connection and reaches the delay time of the
reverse polarity protection, the system would enter the mode of reverse polarity
protection and turn off the discharge MOS. The system wouldn’t recover by itself unless
remove the rectifier or properly connected rectifier.

ASTERION RTL battery system manual
13
3.3.3 Temperature protection
•Cell temperature protection
There are several thermal sensors to monitor the cell temperature, if the temperature
of any cell is higher than 70℃or lower than 0℃，the BMS will stop charging, this is
charge temp. protection; If the temperature of any cell is higher than 75℃or lower than
﹣20℃(﹣40℃)
2
，BMS will stop the discharge. This is the discharging protection. The
settings are shown as No. 12 in table 3.8.
•PCB overheat Protection
There is a thermal sensor to monitor the PCB temperature, if the PCB temperature is
higher than 95 ℃, it will trigger the PCBprotection and stop charging or discharge until
the temperature drop to normal range. The settings are shown as 14 in table 3.8.
3.3.4 CELL BALANCE
During charging, If all cell voltages are greater than 3.40V and the voltage difference
between cells ΔU＞40mV, BMS will trigger the balancing process, the balance current
is designed base on the capacity of battery pack.
ΔU=max. Cell voltage –min. Cell voltage
3.3.5 DISPLAY (OPTIONAL)
The display screen is only for display –when the battery is on, it can show the battery
information. There are four buttons: Enter, Back, Up, Down.
By pressing the Enter the button, you can check battery cell voltage, Temperature and
Parameters Information. Press the Enter button to check the information of the parameter
that the cursor is pointing at. To scroll through the parameters press Up and Down buttons.
