Abstract

Provided are a charging device and a vehicle capable of reducing the amount of noise flowing into a quick-charging facility. The pair of charging lines connecting the quick-charging facility ( 20 ) to an onboard battery ( 30 ) are referred to as quick-charging lines, and each of these quick-charging lines is provided with a relay ( 16 - 1, 16 - 2 ). Each relay ( 16 - 1, 16 - 2 ) is used to switch the current flowing in the respective quick-charging line on and off, the current being switched on during quick-charge and being switched off during normal charging. Each quick-charging line has a Y-capacitor ( 17 ) connected thereto closer to a QC port ( 15 ) than the respective relay ( 16 - 1, 16 - 2 ).

Claims (45)

1. A charging apparatus comprising:

a first noise filter that is coupled to a connector, the connector being configured to couple a direct-current power source to a battery, wherein the first noise filter reduces noise;

a second noise filter that is coupled to an AC/DC converter that converts alternating-current power supplied from an alternating-current power source to a direct-current power, the second noise filter being operative to reduce noise;

a relay that is disposed between the first noise filter and the battery, the relay switches on and off a current flow

wherein, the relay switches the current on when the battery is electrically coupled to the direct-current power source.

2. The charging apparatus according to claim 1 , further comprising:

a DC/DC converter that lowers a direct-current power supplied from the battery and supplies the lowered direct-current power to electric components, the DC/DC converter is coupled to the first noise filter.

3. The charging apparatus according to claim 1 , further comprising:

an air-conditioning compressor that uses the direct-current power supplied from the battery to compress a refrigerant for air conditioning, wherein the air-conditioning compressor is coupled to the first noise filter.

4. The charging apparatus according to claim 1 ,

wherein the second noise filter is disposed on an alternating-current power source side with respect to the AC/DC converter.

5. The charging apparatus according to claim 1 ,

wherein the first noise filter is a Y capacitor.

6. The charging apparatus according to claim 1 ,

wherein the second noise filter is a Y capacitor.

7. The charging apparatus according to claim 6 ,

wherein the AC/DC converter includes a transformer.

8. A charging apparatus comprising:

a first noise filter that is coupled to a connector, the connector being configured to couple a direct-current power source to a battery, wherein the first noise filter reduces noise; and

a relay that is disposed between the first noise filter and the battery, the relay switches on and off a current flow,

wherein, the relay switches the current on when the battery is electrically coupled to the direct-current power source.

9. A charging apparatus comprising:

a first noise filter that is coupled to a connector, said connector being configured to connect a direct-current power source to a battery, wherein the first noise filter reduces noise; and

a relay that is disposed between the first noise filter and the battery, the relay switches on and off a current flow,

wherein the first noise filter includes at least one of a Y capacitor, an X capacitor, a coil, or a ferrite.

10. The charging apparatus according to claim 9 ,

wherein the first noise filter is a Y capacitor.

11. The charging apparatus according to claim 9 ,

wherein the first noise filter is an X capacitor.

12. The charging apparatus according to claim 9 ,

wherein the first noise filter is a coil.

13. The charging apparatus according to claim 9 ,

wherein the first noise filter is a ferrite.

14. A charging apparatus comprising:

a first noise filter that is coupled to a relay that switches on and off a current flow,

a connector that is configured to connect a direct-current power source to a battery,

wherein the first noise filter is disposed between the relay and the connector.

15. The charging apparatus according to claim 14 ,

wherein the first noise filter includes at least one of a Y capacitor, an X capacitor, a coil, or a ferrite.

16. The charging apparatus according to claim 14 , wherein the first noise filter is a Y capacitor.

17. The charging apparatus according to claim 14 , wherein the first noise filter is an X capacitor.

18. The charging apparatus according to claim 14 ,

wherein the first noise filter is a coil.

19. The charging apparatus according to claim 14 ,

wherein the first noise filter is a ferrite.
