NTC 100A 16S 48V Battery Management System BMS

Product: Smart BMS with Bluetooth for 16S 48V LifePO4 Battery Pack With NTC 100A Discharge Current

Customer can adjust the paramter of overcharge or overdischarge by the parameter sitting if customer need to.

Attention:

Customer need to identify the battery's series, then choose the same series BMS. Such as your battery is 24S, you must choose 24S BMS, can not choose 20 or other one. The number of series of BMS is fixed ,not adjustable once the BMS is shipped out .

◆ Control instructions: remote control device monitoring.

◆ Vehicle icon: data transmission send command

◆ Statistical report: Collect the data information, the customer can monitor the battery capacity & other alarm infomation.

◆ Electronic fence: fence setting limit range.

◆ Device information: device parameter information, etc.

The information on your battery can be checked on your host computer, then you can monitor your battery status anytime. Which is easly control your device. Smart BMS make our life to become easy.

What advantage of the BMS?

1. Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.

2. Strong load ability, use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling.

3. IC itself has power balancing function. The circuit is simple and reliable.

4. Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load won't affect the PCB and the battery.Temperature protection can be added.

5. Extreme low power consumption. The consumption of the whole device is less than 50uA.

6. PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.

How to test if the bms is good or not?

1. Make sure to use the attached detective wires of our bms.

Ensure volt-detect red wires are connected correctly.

2. Connect the wire to the battery pack,measure the voltage through the wire,it should be equal with the voltage of each cell.

If the votage is different,it means wrong wiring.

3. Make sure the voltage is same,plug the bms in.Make the multimeter point to Ω, measure the resistance between P- and B-. If the resistance is 0, then the BMS is good.

BMS wiring directions

First, Preparation before installation.

Make sure the batteries are of good consistency.The volt difference is no more than 0.05V,inner resistance is no more than 5mΩ,capacity difference lower than 30mAh. Connect the batteries in parallel first and then in series.the better performance of batteries consistency is, the higher performance of the BMS.

Second, wiring instructions.

Attention: please use our wires for our BMS.Don’t use other factories’ wires which can’t match with our BMS.

Step 1 B-(blue thick wire): Connect to battery pack total negative pole -

Step 2, Disconnect the wires for batteries from the BMS side.

Step 3,Connect the wires to batteries. Start from the thick black wire to total negative pole(B1-),then connect the 2^nd red thin wire to the 1^st battery positive pole(B1+)

B2+,B3+B4+......till the last red thick wire.

Step 4,Finishing all the wires to each batteries,don’t plug into the BMS directly. We suggest you use multimeter measure the voltage of two adjacent metal terminals(You can see the white connector with silver metal pins on the BMS).if the voltage is 3.0~4.2V(LiNCM),2.0~3.6V(LiFepo4), 1.5~2.75V(LTO),which means the wiring is correct.

Step 5,Ensure the wires are connected to batteries correctly, all voltage is normal, you can plug the wires into the BMS.

Step 6 P-: Connect P-(black thick wire) to load - and charger -

(if you ordered “common port”)

Charger+ connect to C-(yellow wire) load+ connect to P-(Black thick wire)

(if you ordered “separate port”)

Step 7 charger+ and load+ connect to battery +,please use thick wire

Third, Measure the total volt of the pack, and the output voltage of the BMS.if the voltage is the same,it means the wiring is correct.You can use the BMS now. Otherwise please check the wiring again according to the tips above.
