5 Installation Steps under Parallel Connection
If voltage difference is measured more than 1V, the difference shall be adjusted to be less
than 1V either by charging the battery with lower voltage or discharging the battery with
higher voltage before conducting the parallel-connected installation.
Step 1
Install battery.
Power on two batteries in condition of no
load, measure their voltages with a
multi-meter and confirm the voltage
difference not more than 1V. After that, power
off two batteries and install them according to
the procedures specified in Section 3.3. Keep
the minimal distance between two batteries,
wall and battery, bus bar box and wall as
shown (unit: mm)
Step 2
Insert power cables into battery terminals.
Make the power cables of both batteries
based on Section 4.2 Step 2. Plug one end of
positive and negative terminals into DC
breaker. Respectively measure the positive
and negative terminal blocks of two batteries
with a multi-meter, and ensure the voltage
outputs under off mode are both 0V. After
that, plug the other end of power cables into
terminals on two batteries.
Step 3
Insert network cables into battery terminals.
Make RS485 and CAN network cables based
on Section 4.2 step 3. Connect two batteries
with the RS485 network cable, and connect
battery and PCS with the CAN network
cable. Specifically, Plug RS485 network
cable into one network port of each battery,
plug one end of CAN network cable into the
CAN network port of any battery, and plug
the other end into PCS network port.
