Testing Methodology
1.4.1.
Pre-Charge
In order to stabilize the testing battery, a pre-charge step is introduced at the start of all steps in each
methodology automatically. The system will apply a small charging current (200mA) for 5 minutes.
1.4.2.
Waken Charge
Small current rate is used to charge the battery pack. It will not check for the output current since some batteries
will not allow any current flow during the initial stage. The Waken Recover will be self terminated in programmed
time.
