2) Protection functions :
This BMS has applied with high quality IC chip specially for lithium battery protection purpose .highly detection precision degree on over-charge,over-discharge,voltage balancing ,and with detection on wires disconnection functions,with three layers of over-discharge and over-current detections and delay times in detecting process.( Over-current 1,over current 2,short cicircuit protection ) . short-circuit of charging port ,with two layers protection against over-voltage when charging :
3) With Mobile phone operation software systme to manage the detecting the battery working status and some parameters setting . also this board can be available for the PC operation and Parameters setting on the computer .
5) This BMS will includes such list :
with one Bluetooth module for Android system only ,4.3Version Above . with wire and connector for the Battery and Software system of mobile phone will be sent to the buyer .
And we can design and produce Battery protection circuit board in according to client’s demand with certain
reasonable order quantity .
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
What Bluetooth Communication Module can do ?
IOS APP for apple devices :
PC communication and parameters display pages :
A. Firstly ,Please connect two 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 !!!
9) Precautions for use
1. When in use, design parameters and work conditions must be followed, and the parameters in this specification must not be violated, otherwise it is easy to damage the protection plate, and then damage the battery pack.
2. When in use, there should be corresponding electro static-free measures for testing, installation and contacting with the protection board.
3. The charging port can withstand the specified DC voltage. If the charger is higher than this voltage, it cannot guarantee that the protection board will not be damaged. Please use the charger according to this specification. It is better to choose the charger with the function of closing the trickle current at the end of charging current, so as to achieve double security. Chargers without trickle current closed are designed for lead-acid batteries and do not work with lithium.
4. When in use, Pay attention to the electric lead, electric soldering iron and solder splash. Do not enable them to touch the components and parts on the circuit board; otherwise the protection board may be damaged.
5. The maximum discharge current is the maximum current that lasts for a few seconds. During the test, it cannot last too long to avoid overheating damage of power MOS.
6. When assembling the protection board and the battery pack, do not place the heat dissipating aluminum plate close to the surface of the cell. Otherwise, the heat will be transferred to the cell, affecting the safety of the battery pack.
7. If abnormal conditions occur during use, please stop using it immediately, return it to the original factory or ask professional maintenance personnel for maintenance.
8. If it is a split protection board, it is forbidden to use P- as a charging port. Because P- is used as a charging port, the battery pack has no overcharge protection. It is forbidden to use C- as a discharge port at the time of splitting
9. It is forbidden to use two or more protection boards in series and in parallel.
10. The protection board has already done a lot of reliability tests, the reliability is far higher than the general protection board on the market, and the process of the cell must be ensured at the same time, so as to reduce the occurrence of combustion as much as possible.
11. This BMS does not have 0V charge function,the battery performance will be deteriorated seriously and even dead
12. In order not to damage the battery ,user should charge the battery periodically when the battery does not work for long time ( battery capaicty are more than 2Ah , storage time exceeds 3 months) ,after discharge compeltely ,please charge the battery in time within 12 hours to prevent the battery from discharge to 0Volt due to self-current consumption with the battery . client should label the battery with clearly battery manitenance instructions to improve the battery heathly .
13. please do not make reverse charge as this bms does not have anti reverse charge function .any reverse charge will damage our BMS probably
10) Safety Precautions:
Our company is committed to improvement of quality and reliability, but in general, there will be a certain probability of failure in electrical components and parts, with different environment and conditions, the durability will be different. When in use, the lengthy design is adopted to avoid overload abnormal fever, smoking, and even casualty, fire accidents, social damage, etc.
Reminds : We will send the detail connection drawings to the client with this product if client needs and this BMS will includes all necessories connectors with wire to make sure client can connect it easily . please follow up it correctly to avoid of any mistake ,above connection is only for simple explaination purpose .
1)Do not apply the PCB which beyonds the specified criterias as above :
2)Sometime , the battery may not discharge when connected this PCB , please connect it to the charge and it can recover to the normal status .
3)The PCB may not work normarly When Mixing cells which were over-discharged or over-charged ,
4) Do not shock this PCB with big static even though the PCB has been designed with anti-stastic protection function.
