Charging apparatus
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 ).
