Abstract

The invention relates to a wireless power transfer method, a wireless charging method, and an electric vehicle. The wireless power transfer (WPT) method based on a state of an auxiliary battery and anelectric vehicle (EV) for the same includes receiving, by an EV charging apparatus, a wireless jump start request message from a user terminal; transmitting, by the EV charging apparatus, a primary jump start power according to the wireless jump start request message to the EV; driving an auxiliary power supply device provided in the EV by a secondary jump start power induced by the primary jumpstart power; driving a controller of the EV based on a preset power outputted from the auxiliary power supply device; and charging, by the controller of the EV, an auxiliary battery of the EV.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority to Korean Patent Application No. 2016-0083678 filed on July 1, 2016 and Korean Patent Application No. 2017-0076882 filed on June 16, 2017 with the Korean Intellectual Property Office (KIPO) rights, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a wireless power transfer (WPT) method and an electric vehicle thereof, and more particularly, to a WPT method and an electric vehicle in which the auxiliary battery is first charged with the auxiliary battery discharged, and then , to charge the high-voltage battery of the electric vehicle at the appropriate auxiliary battery state.
