Testing the Charge-Discharge Functionality of the BOSS Using Battery
Racks
This test setup can be used to charge and discharge battery racks at a specific current set point.
As the current flows from the BUS to the BATT terminals the battery rack voltage on the BUS
side will decrease and the voltage of the battery rack on the BATT side will increase.
See the diagram in Figure 36 for a basic setup and follow the instructions below for the test.
Currently Alencon does not have the setup yet to perform battery charge-discharge test.
Figure 37: Charging and discharging of two battery racks using the BOSS
Connect the batteries to the both sides of the BOSS shown in Figure 36.
o
Ensure input and output cables are connected to the terminal block
o
Hit Reset command – wait for BOSS to transition to standby
o
Establish Power Flow Direction i.e. BUS
BAT
o
Provide Current Set Point
Observe the current flowing at the specified set point.
Change the current set point and observe the actual current flowing at the
specified set point.
Change the direction of the current and give a new current set point. Observe
the actual amount of current and its direction.
o
Observe the voltages on the both sides as the batteries’ state of charge change.
The voltage of the battery which provides current will drop.
The voltage of the battery which takes current will rise.
As the voltages on both batteries change due to their state of charge, the
current through the BOSS will stay constant at a specified set point. Observe
the actual amount of current and confirm that it stays at the specified set point.
o
Once test is complete, shutdown the BOSS using the shutdown command.
o
Disconnect the batteries.
