NOTES:
1.
Always on
means the LCD back-light will be ON forever.
2.
NO
means BMS24T will not cut off charge or discharge but alarm by LED flash and Beeper Sound.
Cut-Off Delay Time
is very important and different for different battery capacities and
applications, please carefully verify and use proper settings for your application. For EV's, you can
select
NO
to control the EV manually,
NOT
controlled by the BMS24T, but when the cell voltage
and/or temperature trigger the absolute maximum or minimum settings, the BMS24T will force
the cut off to Charge / Discharge to protect the battery and prevent damage and the possibility of
fire or explosion.
3.
Current Calibration
is not recommended unless you are using a different shunt than supplied.
Voltage and current is calibrated before delivery for the supplied shunt.
4.
Temperature Alarm OFF means Battery and Difference of battery Temperature is disabled.
5.
Cell Empty Voltage and Cell Full Voltage is to set up cell voltage bar graph, the value should be as
same as Over Charge Protection(P) Voltage and Over Discharge Protection(P) Voltage
6.
Setup the battery starting voltage, when minimum cell voltage over the setup value, the balancing will
start automatically
7.
Setup the minimum cell difference, when the difference of the cell voltage under setup value is
reached, balancing is stopped automatically
8.
Balance switcher, default Balance is OFF,
a)
If balance "in storage" setup is ON, balance will
start in storage status, STORAGE means charge
or discharge current under 1A. So the current
shunt and current sensor wire must be
connected to BMS.
For EV's, balance "in storage"
OFF is suggested. For storage systems, ON is
recommended.
b)
If balance "in charge" setup is ON, balance will
start during charge
c)
If balance "in discharge" setup is ON, balance
will start during discharge
d)
Balance current is 1.2A max. per cell,
9.
Setup accurate battery capacity, then charge or discharge 25% of the battery capacity, the BMS will
calibrate SOC automatically,
