Step 3: Discharge Cycle:
•
Discharge Module to its minimum voltage.
•
Record test time, test current, voltage and total discharge energy at the end of discharge cycle (t3, I3, V3,
E2).
Step 4: Round Trip Efficiency Calculation:
Round trip efficiency = [
total discharge energy (E2)
total charge energy (E1)
] × 100

Test Method for Self-Discharge:
The self-discharge method is designed to see the natural decay of the Module
’s
total voltage over time after
it is fully charged. The result will be influenced by the temperature, the voltage at which the device is charged
and the aging condition.
The following steps describe the process for measuring self-discharge.
Step 1:
•
Charge the Module to its maximum voltage.
•
Record the voltage (Vmax).
Step2:
•
Leave the Module idle for a period of 1 month.
•
Record the open circuit voltage after 1 month (Voc).
Step 3:
•
Self-discharge (%) =
[
Vmax−Voc
Voc
] × 100

FAQs:
Q. How to determine the current status (charging/discharging)?
A. When the current value on the LCD is negative it means the Module is discharging and when it is positive,
it means the Module is charging.
Q. The current reading on the LCD is not accurate for the first charging/discharging Session?
A. The user should wait for 5 minutes after starting the Module for the first charge/discharge session (it is only
one time for warming up).
Q. How to reset the current to zero?
A. Please refer to the video.
Q. If we leave the Module turned ON after it reaches 44V or below. What will happen?
A. When the Module reaches the minimum voltage and below (whether terminal is ON or OFF), the LCD will
