CHARGING APPARATUS FOR VEHICLE AND CONTROLLING METHOD THEREOF
First Claim
1. A vehicle-mounted charging apparatus for charging a portable device battery with a vehicle battery, comprising:
- a storage storing a charging table in which charging quantity ratios of the portable device battery to voltage bandwidths of the vehicle battery are written;
a voltage monitor monitoring voltage of the vehicle battery at a predetermined time interval;
a portable device connector receiving the portable device and charging the portable device battery by using voltage of the vehicle battery; and
a charging controller sensing the portable device received by the portable device connector and controlling the portable device connector so that the portable device battery is charged using voltage of the vehicle battery to a voltage value that corresponds to the monitored voltage of the vehicle battery in the charging table.

Abstract
An apparatus for charging a portable device battery with a vehicle battery is provided. The apparatus includes a storage, a voltage monitor for monitoring voltage of the vehicle battery, a portable device connector, and a charging controller. The storage stores a charging table in which charging quantity ratios of the portable device battery to voltage bandwidths of the vehicle battery are written. The charging controller controls the connector so that the portable battery is charged to a desired value of voltage that corresponds to the monitored voltage in the charging table. With this apparatus, it is possible to charge conveniently, among others.
