Abstract

A power charging apparatus and a battery apparatus quickly charge a battery with power by separately charging each battery cell with power. The power charging apparatus includes: a power supplier supplying power; and a charging part having at least two chargers corresponding one-to-one to at least two battery cells connected to each other in parallel, each of the at least two chargers charging the corresponding battery cell with power transmitted from the power supplying unit. The battery apparatus includes: a battery having at least two battery cells connected to each other in parallel; and a charging part having at least two chargers corresponding one-to-one to the at least two battery cells and charging the at least two chargers with power received.

Claims

1. A power charging apparatus, comprising:

a power supplier configured to supply power; and

a charging part comprising chargers configured to receive the power from the power supplier to charge a battery,

wherein the battery comprises battery groups connected to each other in parallel, and each of the battery groups comprises battery cells connected to each other in series, and

wherein each of the chargers charges one battery cell of a corresponding one battery group.

2. The power charging apparatus of claim 1, wherein the power supplier supplies power to the charging part in a wired scheme.

3. The power charging apparatus of claim 2, wherein each of the at least two chargers receives power from a plurality of power sources which are independent from each other.

4. The power charging apparatus of claim 2, wherein each of the at least two chargers is insulated from each other.

5. The power charging apparatus of claim 1, wherein the power supplier transmits power to the charging part in a wireless scheme.

6. The power charging apparatus of claim 5, wherein the power supplier includes:

a power converter providing a preset power; and

at least one power transmission coil transmitting power from the power converter in a wireless scheme.

7. The power charging apparatus of claim 6, wherein each of the chargers of the charging part includes:

a power reception coil receiving power transmitted from the at least one power transmission coil in a wireless scheme; and

a charging controller receiving power from the power reception coil to thereby control a current value of power charged into the corresponding battery cell.

8. The power charging apparatus of claim 7, wherein a number of the power transmission coils corresponds to a number of the power reception coils.

9. A battery apparatus, comprising:

a battery comprising battery groups connected to each other in parallel, wherein each of the battery groups comprises battery cells connected to each other in series; and

a charging part comprising chargers, wherein each of the chargers charges a corresponding one battery cell of a corresponding one battery group.

10. The battery apparatus of claim 9, wherein the charging part receives power in a wired scheme.

11. The battery apparatus of claim 10, wherein each of the at least two chargers receives the power from a plurality of power sources which are independent from each other.

12. The battery apparatus of claim 10, wherein each of the at least two chargers is insulated from each other.

13. The battery apparatus of claim 9, wherein the charging part receives power in a wireless scheme.

14. The battery apparatus of claim 13, wherein each of the chargers of the charging part includes:

a power reception coil receiving power transmitted in the wireless scheme; and

a charging controller receiving power from the power reception coil to thereby control a current value of power charged into the corresponding battery cell.

15. A charging apparatus configured to charge a battery having battery groups connected to each other in parallel, wherein each of the battery groups has battery cells connected to each other in series, the apparatus comprising:

a charging part comprising chargers receiving power from an external power supplier to the battery,

wherein each of the chargers charges one battery cell of a corresponding one battery group.

16. The charging apparatus of claim 15, wherein the charging part receives power in a wired scheme.

17. The charging apparatus of claim 15, wherein the charging part receives power in a wireless scheme.

18. The charging apparatus of claim 15, wherein each of the chargers of the charging part includes:

a power reception coil receiving power transmitted in the wireless scheme; and

a charging controller receiving power from the power reception coil to thereby control a current value of power charged into the corresponding battery cell.

19. The charging apparatus of claim 15, wherein each of the chargers is insulated from each other.
