6.4 Communication interface
6.4.1 Cascade communication interface
The number of “3” in Pic. 6-1 represents RS485 communication
ports which communicate with upper computer and the other modules
in the cascade connection among the modules. The ports adopt two
8P8C straight PCB welding telephone sockets (round pin). The
module panel is configured with two RS485 ports, which are serial
ports physically. When the battery modules are cascaded, the
communication address 000001 is defined as the master module, and
the others are defined as the slave module. The slave module can
communicate with the master module through the RS485. The master
module manages the data of each battery in the cascade system.
RS485 definition is shown in Table 6-3.

the master battery module can communicate with the upper computer.
When the modules are cascaded, only the master module can
communicate with the upper computer and upload data, status and
information of all of the battery module in the cascade system, which
achieves central monitoring and management, and realizes several
remote functions. RS232 communication interface definition is shown

The number of “9” in Pic. 6-1 represents the dry contact, which is
an interface through which the battery module sends the alarm or
protection signals. When the BMS has a protection or warning signal,
the dry contact sends a switch signal through the corresponding
interface.

6.9Air switch
The number of “11” in Pic. 6-1 represents the air switch, which
is used to disconnect the battery module and the other equipment
when the battery module is short-circuited or in over-current
condition.
6.10 Gyro anti-theftfunction(optional)
The BMS has a gyro anti-theft function, which can be
controlled by the host computer software to. By default, the gyro
anti-theft is activated by charging method.
The BMS PC software can set the gyro anti-theft function
activation mode. When use charging activation to activate the gyro
anti-theft function, the BMS detects that the charging current is
greater than 5A, and the time more than 30s, BMS automatically
activates the gyro anti-theft function.
After the gyroscope is fixed, the initial position state of the
gyroscope can be set by the PC software. When the gyroscope module
has an angular offset of more than 30°in any direction, After a period
of time delay (default 3s), BMS turn off the discharge MOSFET, and
lock the battery. The battery can be charged normally but cannot
discharge any more.
The locked battery can be unlocked by the host computer
software. If the gyroscope returns to the initial position after
unlocking, the battery can be charged and discharged normally. If the
gyroscope module is still offset from the initial position by 30°, the
BMSwill still delay for a period of time (default 3s). and then turn off
the discharge MOSFET, cut off the output and lock the battery. The
battery can be charged normally but cannot discharge.

6.11 GPS module installation window
The number of “12”in Pic. 6-1 represents theGPS reserved
window，When it is necessary toinstall the GPS module, remove the
screws at four corners and fix the GPS module witha cable tie。
7.Systemworking principle and parameters
7.1 Systemworking principle
48V100Ah LFP back up battery module working principle is
shown in Pic. 7-1. The rectifier inputs AC220V power source, and
output DC -48V. Under normal grid conditions, the rectifier supplies
the working current for the load and at the same time charges the
battery module. When grid is off, the battery module supplies direct
current for the load, which achieves uninterrupted power supply.
When the battery module voltage is extremely low, the BMS will
automatically cut off powersupply to extendthe battery life.
