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 battery to its maximum voltage.
•
Record the voltage (Vmax).
Step2:
•
Leave the battery idle for a period of 1 month.
•
Record the open circuit voltage after 1 month (Voc).
•
It can be seen from the graph that as
discharge current rate is increased, the
time required to discharge the Module is
decreased.
•
Similar to Module charge graph, also
while discharging, there is dramatic
voltage decrease from 53V to 50V in less
than 9 minutes regardless of discharge
current rate. Between 50V to 44V there
is linear behavior in all discharge voltage
curves.
Regarding the discharge test with 4
different
current
rate,
ambient
temperature reaches the maximum
value when Module is fully discharged
and there is quite correlation between
consumed
energy
and
Module
ambient temperature. Temperature
increase window is 5 Celsius.
