Title:
ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/064794
Kind Code:
A1
Abstract:
This EHC (140) is configured so as to electrically heat a catalyst for purifying the exhaust gas discharged from the exhaust channel of an internal combustion engine installed in an electric vehicle, when power is on. A charger (120) converts AC power, which is supplied to a charging port from an external power source (210), into charging power for a storage device (70), by using a power conversion route including an isolation transformer (330). The EHC (140) is electrically connected to power lines (352p, 352g) to which DC voltage is outputted, and provided on the primary side of the isolation transformer (330) on the power conversion route. When the EHC (140) is operated while driving the vehicle, the charger (120) uses an inverse transformation for some of the power conversion when charging externally, and converts power from the storage device (70) into DC voltage to be outputted to the power lines (352p, 352g) connected to the EHC (140).
