Abstract
An embodiment charging apparatus includes a main battery, a charger configured to generate an initial charging power source by receiving a direct current (DC) power source from an auxiliary battery installed separately from the main battery or by receiving an alternating current (AC) power source to execute an initial charging operation, and a first switch configured to block or conduct an electrical connection between the auxiliary battery and the charger to thereby execute the initial charging operation depending upon whether the AC power source is supplied. The initial charging operation is terminated when the initial charging power source reaches a preset reference value calculated by multiplying an output power source of the main battery by a preset setting value.
Claims20
A charging apparatus comprising:
- a main battery;
- a charger configured to generate an initial charging power source by receiving a direct current (DC) power source from an auxiliary battery installed in a vehicle separately from the main battery or by receiving an alternating current (AC) power source to execute an initial charging operation;
- and
- a first switch configured to block or conduct an electrical connection between the auxiliary battery and the charger to thereby execute the initial charging operation depending upon whether the AC power source is supplied;
- wherein the initial charging operation is terminated when the initial charging power source reaches a preset reference value calculated by multiplying an output power source of the main battery by a preset setting value;
- and
- wherein when the AC power source is not supplied, the first switch is turned on to conduct the electrical connection between the auxiliary battery and the charger.
A charging method comprising:
- switching between blocking and conducting an electrical connection between an auxiliary battery and a charger using a first switch depending upon whether an alternating current (AC) power source is supplied, wherein switching comprises conducting the electrical connection between the auxiliary battery and the charger by turning on the first switch when the AC power source is not supplied;
- executing an initial charging operation by receiving a direct current (DC) power source from the auxiliary battery using the charger installed in a vehicle separately from a main battery or receiving the AC power source to generate an initial charging power source;
- and
- terminating the initial charging operation when the initial charging power source reaches a preset reference value calculated by multiplying an output power source of the main battery by a preset setting value.
The method of claim ii, wherein the first switch is turned on when the vehicle travels or requires the initial charging.
A charging method comprising:
- electrically connecting an auxiliary battery and a charger when an alternating current (AC) power source is not supplied;
- executing an initial charging operation by receiving a direct current (DC) power source from the auxiliary battery using the charger installed in a vehicle separately from a main battery;
- and
- terminating the initial charging operation when the initial charging power source reaches a preset reference value calculated by multiplying an output power source of the main battery by a preset setting value.
