Abstract
A charging device includes a charger configured to use power entered from an external device to charge a secondary battery with a charging current at a set current value, and a charging controller configured to set the current value. The charging controller sets, at beginning of charging of the secondary battery, the current value to a set value among a plurality of predetermined set values, and sets, during charging of the secondary battery, when an input voltage from the external device lowers below a predetermined value, the current value to another set value among the plurality of set values.
Claims7
A charging device comprising:
- a charger configured to charge a secondary battery with a charging current at a current value being presently set, the charging is carried out by using power entered from an external device;
- and
- a charging controller configured to set the current value,
- wherein the charging controller
- sets, at beginning of charging of the secondary battery, the current value to a set value among a plurality of set values predetermined, and
- sets, during charging of the secondary battery, when an input voltage from the external device lowers below a predetermined value, the current value to another set value among the plurality of set values.
