Features

• For the BMS positioned on the battery, with SMBus comm. port via USB tool kit to PC, to gain battery information, helpful for engineering services or via Host with RS232 port to PC; also with CANBus communication port to external devices.
• BMS monitoring battery SoC & SoH, such as Amperes, capacity; temperature, protection status and cell balance, etc. and also has Mosfet switch under management of the Host or under BMS itself, while the Host convey battery data to the internal devices.
• Conducting back electromotive force (bemf) circuit design.

Wiring Diagram and steps to install

1. Steps to install battery pack with BMS. Please follow from (1) to (5)

(1) Plug temperature sensors, JA5, JB5, JC5, JD5 onto the BMS..

(2) "B─" at CON3 of the Mosfet switch board, connected to the "─” negative pole of battery pack.

(3) CON6 marked as "BT +" of the Mosfet switch board shall be connected to "+ (the positive pole)" of the battery pack. This cable is used to conduct possible Back-EMF energy.

(4) On battery pack, its "BV9 ~ BV16 (Cell9 ~ Cell16) voltage sense wires" shall be connected to CON2 of the BMS board.

(5). On battery pack, its "GND, BV1 ~ BV8 (Cell1 ~ Cell8) voltage sense wires" shall be connected to CON1 of the BMS board.

After these, the red LED (LDA1) of BMS board will turn luminous for about 6 seconds and then turns off,

This red LED indicator will blink at an interval of every 8 seconds, indicating BMS normally operating.

(6). Fuel Guage LED display for Battery SoC (LED display on option)

 63mm*33mm TO BMS JB1

2. Steps to uninstall:

1.  Remove link on the "P─" at the CON5 of the Mosfet switch board, which connects to the "─ “ negative pole of the charger" or "load". 

2. Disconnect or unplug each of its connectors according to the reverse order of the installation, from (5) – (4) – (3) - (2).
