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.
