BMS protection board installation and wiring
1 Charge and discharge line connected to BMS board negative C-port 4 blue lines must be connected to BMS board same port design Charge and discharge load are connected to BMS board C-port
2 Battery negative line connected to BMS board B-port wiring Be sure to connect the negative pole to the B-port of the BMS board first. Insert the sampling line B-, C- output line. Do not press or twist the wire. Be sure to solder. Due to the pressure line or Screw wire burnout protection board is not guaranteed
1 CAN communication JN1939 protocol CAN2.0A/B communication for use with vehicle controller/motor controller/instrument/charger
2 RS485-1 communication with isolation special charger
3 RS485-2 communication Support RS-485 communication 2500V isolation. Baud rate standard 19600.
4 built-in Bluetooth
When the equalization switch is turned on or off, any string exceeds the control voltage. The charging automatically turns on the equalization until the differential voltage is set to stop the equalization. The equilibrium temperature is reached.
And voltage drop will stop equalization
Equalization is on. Any string exceeds the equalization start voltage. Exceeding the set differential voltage turns on the equalization automatic equalization. To control the voltage and set the differential voltage. Stop the equalization.
There is a discharge current and an equilibrium temperature to the set value. The equilibrium temperature is not inserted and the voltage is dropped.
6 Current correction: Under discharge condition. Use the meter to read the correct current discharge APP and the upper computer input actual current value. The unit is mA directly press the correction button to correct.
Look at the input current of the display to the host
7 SOC correction: First, fill the actual capacity of the battery pack into the capacity setting. Set the charging protection voltage to correct the current when charging the current to the BMS protection SOC.
8 Actual capacity correction: First fill the battery to the protection voltage (the highest voltage can not be lower than the charge recovery voltage)
After the power is discharged (discharged to the set protection voltage), the calibration capacity inside the actual APP will come out.
