Abstract: The present disclosure relates to a contactless charging device and a contactless charging method using the same, and particularly, to a location zone-based contactless charging device and a contactless charging method using the same that enable multiple passengers to be charged simultaneously in a one-by-N format without a need for direct tagging of a vehicle terminal, by utilizing a step sensor built into a passenger terminal. The present disclosure may accurately and automatically perform the charging without the terminal tag even when multiple passengers board and alight at the same time, such as in the tram, thereby reducing a boarding and alighting time and providing convenience and safety to the passengers. In addition, the present disclosure may accurately determine the boarding and the alighting of the passenger even when sensing of some beacons installed at multiple stations is uncertain or some beacons are broken, thereby improving reliability and preventing incorrect charging.
