B.
Relation of MBMS and battery strings (PowerCube-M2s) in the ports of Ethernet Switch
The both side of BMS to MBMS communication cable must be marked with labels.
The last port of Ethernet Switch is for the MBMS.
From the 1
st
port to the n
th
port are for the corresponding battery string (PowerCube-M2).
3.6.3 ADD Switch Setting (Address Assignment)
ADD Switch - Battery Controller
is a 6 bit dial switches to manually
distribute the communication address of the battery system. Down
position is OFF, means “0”. Up position is ON, means “1”. 1
st
bit to 5
th
bit
is for address, and the 6
th
bit dial switch support a 120
Ω
resistance (
Terminal Resistance
).
ADD Switch - MBMS
is a 6 bit dial switches to manually distribute the communication address of
the battery system. Down position is OFF, means “0”. Up position is ON, means “1”. 1st bit to 4th
bit is for address, the 5th and the 6th bit dial switch support a 120
Ω
resistance (Terminal
Resistance).
3.6.3.1 Under communication for single BMS (battery string qty. 1 set)
The BMS’s first five bits must set in below <
BMS’s Address Configure Table
>. The last BMS’s terminal
resistance must set in “1” (X=1);
The address is configured follow ASCII code: (“X” is terminal resistance).

3.6.3.2 Under CAN Communication Mode between MBMS and BMS (battery string qty. s6 set)
The BMS’s first five bits must set in below <
BMS’s Address Configure
Table
>. The last BMS’s terminal resistance must set in “1” (X=1), and
other BMS’s terminal resistance must set in “0”.
