JK Smart BMS JK-B1A8S20P/JK-B2A8S20P User Manual
m)
Max Discharge Curr.(A), Discharge OCP Delay(S), Discharge OCPR Time(S)
When discharging the battery pack, the current exceeds the "Max Discharge Curr.(A)" and the duration
exceeds the "Discharge OCP Delay(S)" time, the BMS generates the "discharge over-current alarm" and
turns off the discharge MOS at the same time. After the time of "Discharge OCPR Time(S)", BMS will
release the "Discharge Over-current Alarm" and turn on the Discharge MOS again.
Example: Set the " Max Discharge Curr.(A)" to 100A, " Discharge OCP Delay(S) " to 10 seconds, and "
Discharge OCPR Time(S)" to 50 seconds. If the discharge current exceeds 100A for 10 seconds, the
BMS will generate the 'discharge over-current alarm' and turn off the discharge MOS. 50 seconds after
the alarm is generated, the 'discharge over-current alarm' will be released and the BMS will turn on the
discharge MOS again.
n)
SCP Delay(us), SCPR Time(S)
When short-circuit protection occurs, the short-circuit protection is released after the time set by “SCPR
Time(S)”..
o)
Start Balance Vol.(V)
The Start Balance Vol.(V) is used to control the voltage phase of balancing. Balancing will be triggered
only when the cell voltage exceeds this value and the maximum voltage difference between the cells
exceeds the balancing trigger voltage difference.
p)
Max Balance Cur.(A)
The balancing current indicates the continuous current of discharging the high-voltage cell and charging
the low-voltage cell during the energy transfer. The Max Balance Cur.(A) indicates the maximum
current in the energy transfer process, and the maximum balancing current should not exceed 0.1C.
For example: The balancing current for 20AH battery should not exceed 20*0.1=2A.
q)
Charge OTP(
℃
), Charge OTPR(
℃
)
When the battery temperature exceeds the "
Charge OTP(
℃
)" value during charging, the BMS
generates the "Charge Over Temperature Protection" alarm and turns off the charging MOS. When the
temperature falls below the "
Charge OTPR(
℃
)", the BMS release the "Charge Over Temperature
Protection" alarm and turns on the charging MOS again.
r)
Charge UTP(
℃
), Charge UTPR(
℃
)
When the battery temperature is lower than the "Charge UTP(
℃
)" value during charging, the BMS
generates the "charge low temperature protection" alarm and turns off the charging MOS. When the
temperature is higher than "
UTPR(
℃
)", BMS will release the 'charge low temperature protection' alarm
and turn on the charging MOS.
