The Sirius Module does not require periodic maintenance.
12.
Disposal:
Dispose according to local regulation.

Test Procedures:
13.1 Round Trip Efficiency Test:
Round Trip efficiency test is performed to evaluate the performance of the Module. There are three factors to
be considered in the design of the test cycle for round trip efficiency.
•
How to charge and discharge the Sirius Module.
•
At what voltage to start and end the charge/discharge?
•
At which points to do the measurement.
Considering the efficiency and cost involved in the production line, we used constant current load test method
for Round trip efficiency characterization.
Test Equipment:
•
DC Charger test system or any other test system which can be used to charge and discharge Module with
test cycle programing. We used
WRL48V80A27cd
DC Charger Motor for charging and
WRL-FDY48L20
Battery Discharge Tester for discharging.
Test Temperature:
•
Room temperature 23
o
C ±2
o
C.
•
Temperature controlled chamber can be used if testing at any environment other than room temperature.
Test Current:
•
Different current within the maximum limit specified by the test equipment manufacturer can be applied
to the test.
Test Process:
Step 1: Rest (open circuit):
•
Record test time, test current, and voltage at the start of the test (t1, I1, V1).
Step 2: Charge Cycle:
•
Charge voltage to its maximum voltage.
•
Record test time, test current, voltage and total charge energy at the end of charge cycle (t2, I2, V2, E1).
