Internal Electrical Connections of the Battery
Note:
A. The internal connecting wires are packed in the box;
B. Before connecting cables, ensure that the switches of the devices are
3.1 Connection of Battery Cable
The battery expansion modules in the ESS battery cabinet are
connected in series.
The top battery expansion module "+" is connected by
the power control module "battery cascading terminal
+", the top battery expansion module "-" is connected
to the next battery expansion module "+", and so on.
The lowest battery expansion module "-" is connected by the
"battery cascading terminal" of the power control module- .
3.2 Connection of Communication Cables
The ESS Battery Cabinet uses Daisy chain for internal
communication.
As shown in the figure, the battery expansion modules are
connected one by one.
The battery expansion module at the top is connected with the
power control module internal communication interface
the bottom battery expansion module's internal COM port is
connected to a terminal resistance.
3.3 Connection of Internal Ground Cable
For the internal ground cable of the ESS Battery Cabinet,
connecting each component unit one by one as shown in right
picture.
turned off. Otherwise, high voltage electric shock and equipment
