All parallel power cables should be of the same length:
(L1 = L2 = L3 = L4 = L5 = L6 = L7 = L8)
You are advised to use the EV power cables with minimal size of 25 mm2 or 3AWG
(600V, 125A) and length min.1500mm.
The P+ and P- power line between the busbar and the PCS should be able to
support 200A rated current, You are advised to use the EV power cable with size
min. 50 mm2 or 0AWG (600V, 210A).
Before assembling Power cable, label the cable polarities correctly to ensure
correct cable connections and identification.
The power cables installation and connection must be carried out by trained
professionals.
The Master battery can automatically identify the Slaves batteries connected in parallel using
its internal software control. The communication terminals Port In and Port Out (RJ45 port) are
integrated with the signal for automatic coding function.
4.3. Parallel Cascade Connection
All parallel power cables should be of the same length.
The parallel system supports an operation with up to 4 parallel connections. The following de-
scribes the connections of a system with four batteries packs, one Master, and three Slaves.
The CAN communication port of the Master pack should connect to PCS;
Port In from the Master pack should not be connected;
The Port Out from the master PACK should connect the Port In of the first slave PACK using
a parallel communication wire;
The Port Out of the first Slave pack should connect to the Port In of the second Slave PACK;
Following the same pattern, the Port Out of the second Slave pack should connect to the
Port In of the third Slave PACK;
The Port Out of the third and last slave PACK should not be connected.
