Can you tell us about the requirements and selection criteria for the Schottky barrier diode (SBD) to be inserted?
Please comment on whether SBDs are appropriately selected for the charging conditions.
The charging conditions are as follows.
<Charge condition 1>
VAC1 input : 12V
VAC2 input : 5V
Charging voltage: 7.2V
CC charging current: 1000mA
Cut-off current: 120mA
Input current limitation: 1600mA
<Charge condition 2>
VAC1 input : 12V
VAC2 input : None(only VC1 input)
Charging voltage: 8.0V
CC charging current: 1300mA
Cut-off current: 160mA
Input current limitation: 1150mA
