Charging device that reduces an amount of noise flowing through a quick charging system in a vehicle
View Patent ↗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 ).
1. A charging apparatus comprising:
a quick-charging line for supplying direct-current power supplied from an external direct-current power source to a battery, the quick-charging line having one end being connected to a line between a battery and a component which becomes a noise source when the component operates during quick charging to the battery, and having the other end being connected to an input side of quick charging,
a first noise filter that is disposed on the quick-charging line and eliminates noise,
an AC/DC converter having a transformer, the AC/DC converter converting alternating-current power supplied from an external alternating-current power source to direct-current power and supplying the power to the battery; and
a second noise filter that is disposed on a normal charging line connecting the external alternating-current power source to the AC/DC converter and eliminates noise.
2. The charging apparatus according to claim 1 , further comprising:
a relay that is disposed on the quick-charging line and switches on and off a current flowing through the quick-charging line, wherein
the first noise filter is disposed on the input side of quick charging with respect to the relay.
3. The charging apparatus according to claim 1 , wherein each of the first noise filter and the second noise filter is a Y capacitor.
4. The charging apparatus according to claim 3 , wherein the relay is switched on during quick charging, and is switched off during normal charging.
5. A vehicle comprising:
a battery; and
a quick-charging line for supplying direct-current power supplied from an outside of a vehicle to the battery, the quick-charging line having one end being connected to a line between a battery and a component which becomes a noise source when the component operates during quick charging to the battery, and having the other end being connected to an input side of quick charging,
a first noise filter that is disposed on the quick-charging line and eliminates noise,
an AC/DC converter having a transformer, the AC/DC converter converting alternating-current power supplied from an external alternating-current power source to direct-current power and supplying the power to the battery; and
a second noise filter that is disposed on a normal charging line connecting the external alternating-current power source to the AC/DC converter and eliminates noise.
6. The vehicle according to claim 5 , further comprising:
a relay that is disposed on the quick-charging line and switches on and off a current flowing through the quick-charging line, wherein
the first noise filter is disposed on the input side of quick charging with respect to the relay.
7. The charging apparatus according to claim 1 , wherein the first noise filter eliminates noise from a plurality of components which become a noise source.
8. The charging apparatus according to claim 7 , wherein the first noise filter is disposed outside the plurality of components.
