Power Selector
Battery pack
to power the BMS. the battery pack must be 16S-24S LiFe or LiPo or LiTO.
External power
supply, BMS24T supports 2S to 24S LiPo, LiFe or LiTo battery pack. The
external input supply
Voltage
range is 13V to 100V.
External power
port
External power input, the voltage should be 13V to 100V, 3A minimum, the current
depends on the relay coil, the connector is 5.5*2.1 DC jack,
Charge controller
Charge controller, connected to relay / DC contactor. will "OPEN" the relay by releasing the
coil power when any cell voltage is OVER setup values. Otherwise the BMS24T will output
12V
power the coil to close the relay when everything is within programmed settings.
The relay must be a "Normally Open" type.
Discharge
controller
Discharge controller, connected to relay / DC contactor. will "OPEN" the relay by releasing
the coil power when any cell voltage is UNDER setup values. Otherwise the BMS24T will
output
12V
power the coil to close the relay when everything is within programmed
settings. The relay must be a "Normally Open" type.
COM1
The COM1 port (black connector) is connected to external device such as Charger. If
connect to Chargery charger, BMS24T can control charge current to shorten charge time
COM2
The COM2 (gray connector) port is connected BMS main unit to display module by gray
spring wire
COM3
Output RS232 level on the port, any external device can read out all data from BMS24T
Temperature
sensor
Two temperature sensors monitor the battery temperature, the sensor must tie to battery
surface or gap of cells where the temperature should be the highest during charge or
discharge. The temperature range is -20 to 150
℃
LED
1)
Connect to high light LED, the LED will flash when any warning event happened
Beeper
1)
Connect to beeper or others to alarm. It will output 12V 25mA max.
Current sense
Connect to single current shunt. Charge current and discharge current can be measured
simultaneously.
USB
Connect to PC update the firmware by Chargery UpdateTool.exe
Socket 1
Connect to 2S to 8S battery,
Socket 2
Connect to 9S to 16S battery. for over 8S battery, please connect 8S battery to socket 1
and then connect to socket 2, such as 8S + 2S for 10S and 8S +5S for 13S
Socket 3
Connect to 17S to 24S battery. for over 16S battery, please connect 8S battery to socket
1 and second 8S to socket 2, then connect other cells to socket 3, such as 8S + 8S + 6S
for 22S
Note:
1)
On the BMS display module
Absolute maximum or Minimum ratings
Maximal cell voltage
LiPo
4.35V
Larger than the absolute maximum voltage,
BMS24T will force to cut off charge
LiFe
3.90V
LiTO
2.80V
Minimum cell voltage
LiPo
2.50V
Less than the absolute minimum voltage, BMS24T
will force to cut off discharge
LiFe
2.00V
LiTO
1.50V
Battery temperature
LiPo&
LiFe&LiTO
1-80
℃
Over the temperature, BMS24T will force to cutoff
the charge and discharge
