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 (41)

1. An onboard 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 through a charge line, 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; and

a relay that is disposed between the first noise filter and the battery,

wherein the relay switches off current flowing in the charge line when the battery is not electrically coupled to the direct-current power source.

2. The onboard 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 onboard 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 onboard 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 onboard charging apparatus according to claim 1 ,

wherein the first noise filter is a Y capacitor.

6. The onboard charging apparatus according to claim 1 ,

wherein the second noise filter is a Y capacitor.

7. The onboard charging apparatus according to claim 6 ,

wherein the AC/DC converter includes a transformer.

8. An onboard 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 through a charge line, wherein the first noise filter reduces noise; and

a relay that is disposed between the first noise filter and the battery,

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

wherein the relay switches off current flowing in the charge line when the battery is not electrically coupled to the direct-current power source.

9. The onboard charging apparatus according to claim 8 ,

wherein the first noise filter is a Y capacitor.

10. The onboard charging apparatus according to claim 8 ,

wherein the first noise filter is an X capacitor.

11. The onboard charging apparatus according to claim 8 ,

wherein the first noise filter is a coil.

12. The onboard charging apparatus according to claim 8 ,

wherein the first noise filter is a ferrite.

13. An onboard 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 through a charge line,

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

wherein the relay switches off current flowing in the charge line when the battery is not electrically coupled to the direct-current power source.

14. The onboard charging apparatus according to claim 13 ,

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

15. The onboard charging apparatus according to claim 13 , wherein the first noise filter is a Y capacitor.

16. The onboard charging apparatus according to claim 13 , wherein the first noise filter is an X capacitor.

17. The onboard charging apparatus according to claim 13 , wherein the first noise filter is a coil.

18. The onboard charging apparatus according to claim 13 , wherein the first noise filter is a ferrite.
