Abstract: A method for an online service provision platform includes establishing a service product database containing a plurality of digitized service products, obtaining a search term from a user, and searching the service product database based on the search term to obtain a plurality of candidate service products. Each digital service product corresponds to a service item identifier, and the service item identifier uniquely identifies a service item and contains a plurality of fields including a category field, one or more sub-category fields, and a service item field. The method also includes displaying the candidate service products to the user to obtain a selected service product chosen from the candidate service products by the user, and performing a service provision process of the selected service product.

Abstract: An electric vehicle charging method includes obtaining charging information about a wireless charging station including at least one charging pad for wirelessly transmitting power to at least one charge receiving pad of the electric vehicle; establishing a charging position between the at least one charging pad and the at least one charge receiving pad; and displaying on a display screen the at least one charging pad overlapped by a virtual charge receiving pad representing the at least one charge receiving pad. The method also includes determining whether the charging position is desired to start a wireless charging session between the charging station and the electric vehicle; prompting a readiness for charging on the display screen after determining that the charging position is desired to start the wireless charging session; and starting the wireless charging session between the electric vehicle and the wireless charging station.
