1. Summary

This series of products is mainly needle 48V series power battery provides a set of data of power battery safety, based on intelligent management products. 

2. Application scope

48V(13~16S)Special in large capacity battery pack.

3. Product features

1) UARTcommunication,Read the voltage, current, temperature, circulation and other data.

2) RS-485 communication,Read the voltage, current, temperature, circulation and other data.

3) can data storage, support 4 channel temperature probe to collect temperature

4) Coulomb power calculation, accurate display of electricity, and has the power to learn.

5) smart dynamic equilibrium.

6) Store data periodically.

3.1 The following functions are extended, the default is not

7)Support switch off start.

4. Produce Specification

The following parameters are the default parameters, the specific parameters of the shipment report shall prevail

5. Function description

5.1 sleep function:

When the battery is not abnormal, static 30S, BMS into the system  sleep, reduce the consumption, at this time the charging and discharging MOS in the open state, charging or discharging can be activated to normal working state. After sleep, the power consumption is less than 100uA

Dormancy activation condition: current (charge, discharge) and communication activation

Note: in the case of a balanced start, do not start dormancy


6. Product connect description

6.1 Product picture

6.2  BMS description of each connection terminal:

Description: all products of Smart li-ion energy are from high to low to connect . That mean you should connect from P17 to P1 if you have 16 cells .

6.3 BMS and battery connection notes


1)step to connect BMS:

A. First, The wire from low to high sequentially welded to the battery pack(Welding it without BMS condition)

B. Connect the pack’s negative pole to the PCB’s B-,Welding the main current positive pole  wire to B+.

C. Confirm winding displacement(B4+,B3+……B1+,B-)welding with the corresponding electrode and the main current’s  negative wire winding to the pack’s negative pole then plug the corresponding’s into the BMS’S connecting terminal

D. After completing the above steps,the cells pack be finished


7.Data monitoring

 7.1 Information display (this picture is for reference only):

Information including voltage, current, temperature, electricity and other real-time data


7.2 BMS Parameter display and change(This picture is for reference only)

In more information interface, you can read the BMS protection parameters and other data, but also has the function of parameter modification.

7.3 Cycle record(This picture is for reference only)

In the cycle record interface, click on the start record, the communication data stored in the computer software running directory, named in time, to save the CVS suffix.

8. Intelligent dynamic balance function

8.1Smart li-ion intelligent dynamic balance method:

1)Intelligent dynamic normal balance (Energy consumption method)

2)Intelligent dynamic initiative balance (energy transfer method)(Patent No:ZL 2015 2 0597739.5).

All of the smart li-ion smart software products include intelligent dynamic normal balance.


9.Smart li-ion SOC algorithm

Intelligent lithium energy smart li-ion using independent research and development of the core algorithm, using the Coulomb method as the basis, coupled with the voltage static curve, the current dynamic curve, and the voltage and capacity change curve, multi line SOC estimation. Can be used in the battery group, to make up for the weaknesses of the Coulomb, the largest program to improve the accuracy of SOC.

10.1 PC communication:$12

The module is TTL to USB function, the use of the module can communicate with PC.

10.2 Bluetooth:$12

The module is a Bluetooth 4 module, using the module Android devices or IOS devices  to communicate, including mobile phones and flat equipment.

10.3 LCD display screen:$16

the module for the OLED display module, the use of the module can be directly read BMS data display, while supporting the Bluetooth function (built-in Bluetooth module)
