1) Introduction and Features：
This is a Smart protection board specially designed for battery packs of.It can be applied to lithium batteries with different chemical properties, such as lithium ion, Li-polymer. Lithium iron phosphate, etc. The protection board has strong loading capacity and the maximum continuous discharge current can reach 1500A.
- 6s 7S 8S 10S series cell protection for Lithium Battery pack (7*4.2=29.4V 8*3.65=29.2V Lifepo4 battery pack ),client can select suitable type based on your battery characteristics
- Various protection functions for charging and discharging ( over-charge , over-discharge ,high or Low temperature protection ,over-current protection , short circuit protection etc ) with double layers protection hardware and software protection .
- Precise SOC calculation with SOC function of automatic learning
- Automatically charge battery function or static balance function for the battery system
- Equipped with Bluetooth module with isolated UART communication which can enable the user to view battery information on our APP or Computer software which can be provided by us .client can use the PC software to set the protection parameters flexibly,client can download software with our appointed link .
Default Parameters setting :
Specification as below is our defaul setting value , clinet can use the PC module to set them on yourside without
problems .if you want us to set it , you can leave a message to us based on your battery specification without problems
Our Smart BMS with Bluetooth function will include free Bluetooth module and connection cables .if client needs PC communication module , you can buy it separately without problems
A.Mobile Phone APP Display and how to set parameters via APP software with the Bluetooth Communication module as below.
What Bluetooth Communication Module can do ?
With Bluetooth Communication Module , the APP Software can be connected , and all information of the BMS can display on your Mobile Phone . and you can set some parameters on Your APP software :Over-protection voltage , Over-discharge protection voltage Rlease voltage of over-charge and discharge .
B .With the PC communication Module as Below ,we can set parameter on PC software like this :
What PC communication Module can do ?
With PC communicaton module , you can set some basic protection parameters the same with APP software ,
and besides the setting scope , PC Module will extended the parameters setting ,such as battery series setting
Cell’s voltage calibration . some battery information input in according to the below pictures, client can choose
the PC Communication module flexibly in according to your practical application purpose
Connection diagram and instructions :
Notice of connection :
A. Firstly ,Please connect bold wires from B- port of the BMS to the negative port of the battery pack .(B- wire should be as short as possible ) ,then connect these voltage detection wires (Please take off these wires from the BMS before connecting these wires to the battery to avoid any connection mistakes )
B. Second ,Please start connect these balance wires to the Battery system from BC0 ,Black thin wire should be connected to the battery negative , and the second wire -white wire BC1 should be connect to the positive port of the first series cell . BC2 should connect to the positive port of second series cell ,and BC3 wire to the third cell’s positive ….connection in this way in order one by one till to the last cell postive port
C. Third . After connection of these balance wires finished , please measure connector voltage from each Neighbouring wires ,the voltage between each neighbouring wires for Li ion battery should be less than 4V and for Lifepo4 Battery should be less than 3.5V ,after confirmation of these wires connection order , you can plug cable connector into the BMS .–wrong connection order will damage our BMS surely . please be carefully with this step .
D. Finally , connect C- wire as negative of charge and discharge , B+ wire as positive of charge and discharge , those wires should
use bold wire to make connection for large current distribution purpose . then please comparing the voltage from the BMS and voltage directly from the Battery to see if they are the same or not . if they are the same value . your connection is correct , otherwise terrible things will happend !!!
