JK Smart BMS JK-B1A8S20P/JK-B2A8S20P User Manual
When the BMS turns on the balancing function and the balancing condition is reached, the balancing
current display area shows the balancing current in real time, unit: A.
When the balancing is in progress, the real-time status of the single unit voltage display area, blue
represents the discharged battery, red represents the battery being charged. The negative balance current
indicates that the battery is discharging, at this time blue flashes, and the positive balance current
indicates that the battery is charging, at this time red flashes.
JK BMS adopts active balancing technology. The principle of balancing is to take power from the high
voltage cell, store it in the BMS, and then discharge it to the low voltage cell.。
p) MOS Temp
Display the temperature of MOS in °C.
q) Battery T1
“NA” is displayed if temperature sensor 1 is not installed. If the temperature sensor 1 is installed, it is
displayed in real time in °C.
r)
Battery T2
“NA” is displayed if temperature sensor 2 is not installed. If the temperature sensor 2 is installed, it is
displayed in real time in °C.
Zone 2 in the figure shows the cell voltage area. The voltage data of each cell in the pack is
displayed in real time, where red indicates the cell with the lowest voltage and blue indicates the
cell with the highest voltage.
Zone 3 of the diagram is to display the resistances of balancing wires. The balance wire resistance
is the balance line resistance obtained from the BMS self-test, the value is only a preliminary
calculation, the purpose is to prevent the wrong connection or poor contact, when the balance
wire resistance exceeds a certain value, the display will be yellow, then can not open the balance.
