1.Parallel Parameter Setting of the Battery
Set up the battery pack that needs to be connected in parallel to the BMS software on the
PC computer via RS485.
Configure[BMS Address] parameter for each battery. The address of each battery is not
duplicated. The address of each battery is defined as 0 for the host and the address of 1 ~
7 for the slave.
2.Communication Line Connection
The communication ports that need to be connected in parallel will be connected in
parallel using the “7# parallel communication line” to connect the communication port
of one of the battery to the next adjacent group of battery port, and the communication
ports of all battery modules will be connected in this order.
The wiring method is detailed in "48V/50Ah parallel wiring diagram".
The communication interface of the device end should be equipped with CAN matching
resistor.
