1、Physical interface and Communication mode
1.1 Physical interface
The serial communication mode is adopted for Physical Interface,which is adopted by standard RS232
communication mode.It provides a information transmission methods by Asynchronous mode,a start bit,a stop
bit,no check bit .The data transmission rate is 9600.
1.2 Communication mode
The Communication mode adopts the Master-Slave response mode.when the PC software or monitoring
equipment initiates communication command as the host,the BMS responds the return command as the slave.if
the host don’t receive the response caomand or error information in 500 ms when the host has sent the
command.in this case,this communication will be failed.

Remark：VER-means communication veision，usually uses V2.5，as 25H.
ADR-means battery pack address,BMS uses four-digit toggle switch to set the address，the address range
is 0~15.
2.3 Data format
2.3.1 Basic data format
Page 4

Beyond that the SOI and EOI is transmitted by 16-hex format,other items is transmitted by 16-hex ascii
format.every byte uses two ascii,for example,when the CID2 = 4HH,the 34H and 42H will be transmitted in
two bytes.

2.3.3 LEDID
LENID means the ascii byte number of INFO,when LENID = 0,that means INFO is not.all data bytes is not
uppt to 4096.
High byte is sent at first and low byte is sent at second for LENGTH information with four ASCII code.
2.3.4 LCHKSUM
The calculation method of check code：D11D10D9D8+D7D6D5D4+D3D2D1D0
After sum, module 16 takes inverse plus 1
For example：
INFO:中 ASCII code number is 18，that’s LENID＝0000 0001 0010B。
D11D10D9D8+D7D6D5D4+D3D2D1D0＝0000B＋0001B＋0010B＝0011B，module 16 is 0011B，0011B takes inverse plus
1 is 1101B，so LCHKSUM is 1101B。
so：LENGTH is 1101 0000 0001 0010B，that’s D012H。
2.4 CHKSUM data faomat
All char ascii code is calculated for sum without SOI,EOI and CHKSUM，the result module 65536 takes
inverse plus 1。
For example：
When send or receive the data sequence：
“~1203400356ABCEFEFC72\R”（“~”is SOI，“CR” is EOI），
So the last five char “FC72\R”FC72 is CHKSUM，
Calculation method：
‘1’＋ ‘2’＋ ‘0’＋ …＋‘F’＋ ‘E’＝31H＋32H＋30H＋…＋46H＋45H＝038EH
038EH module 65536 is 038EH，038EH take inverse plus 1 is FC72H。
2.5 DATA_INFO data faomat
This protocal use the fixed point data type to send information.
1）int format（INTEGER，2byte）
Signed int －32768－＋32767
Unsigned int 0－＋65535
High byte is send first,and the low byte is send second。

5、example
When we use this communication mode,the address is not limited.the BMS response information can be the
BMS address.besides CID2 code is 42H and 44H,other CID code is used for only one BMS pack.for example:
Getting pack analog information：
7E 32 35 30 30 34 36 34 32 45 30 30 32 30 31 46 44 33 31 0D （COMMAND = 01H）
7E 32 35 30 30 34 36 34 32 45 30 30 32 46 46 46 44 30 36 0D （COMMAND = FFH）
Getting pack warn information：
7E 32 35 30 30 34 36 34 34 45 30 30 32 30 31 46 44 32 46 0D （COMMAND = 01H）
7E 32 35 30 30 34 36 34 34 45 30 30 32 46 46 46 44 30 34 0D （COMMAND = FFH）

remark
when communication debugging between monitoring equipment and BMS by RS232,we should pay attention to
this situation:
1、 We should know the BMS is working or not,which can be judged by LED.if all LED is closed,we can push
the key at 3-6 seconds to wake up the BMS.
2、 We should confirm that the monitoring equipment’s baud is suitable with datasheet.
3、 When we analysis the data,please pay attention to the data’s type.
