Abstract

The present invention provides a charging device and a vehicle that reduce the amount of noise inflow to a quick charging facility. A pair of charging lines connecting the fast charging device (20) and the vehicle battery (30) are called fast charging lines, and relays (16‑1, 16‑2) are provided on each fast charging line. The relays (16‑1, 16‑2) switch on and off the current flowing through the fast charging line, and are connected during fast charging and disconnected during normal charging. In addition, on each quick charging line, a Y capacitor (17) is connected to the QC port (15) side than the relays (16-1, 16-2) of each quick charging line.

Description

technical field [0001] The present invention relates to an on-vehicle charger and a vehicle that receive quick charging from a quick charging facility installed outside the vehicle. Background technique [0002] In recent years, electric vehicles (hereinafter, simply referred to as "vehicles") such as electric vehicles (EV: Electric Vehicle) and plug-in hybrid electric vehicles (PHEV: Plug-in Hybrid Electric Vehicle) have become increasingly popular. Such a vehicle is equipped with a large-capacity battery, stores electric energy supplied from the outside in the battery, and runs using the stored electric energy. [0003] As a method of supplying power to the battery of the vehicle from the outside, there is a method in which a charger installed in the vehicle receives AC power from a 100V AC power supply used in general households, converts the AC power to DC, and charges the battery. In this method, in order to prevent the inflow of noise to the AC power supply, a noise r...
