Abstract: A method, apparatus and computer program for supplying power through grouping of charging modules for electric vehicle are provided. A method for supplying power through grouping of charging modules for electric vehicle according to various embodiments of the present disclosure, the method being performed by a computing apparatus, the method includes outputting a first signal in response to receiving power from a power source; collecting a plurality of second signals output in response to each of external plurality of charging modules receiving power; and selecting at least one charging module from among the plurality of charging modules using a parameter of the first signal and the plurality of second signals, and grouping into one group with the selected at least one charging module.

Abstract: The present invention relates to a power supply method of an electric vehicle charger in which multiple chargers are connected to the same power supply source, the power supply method comprising operations of allowing an electric vehicle to be connected to a first charger, generating a charging start signal from the first charger, receiving, by one or more other chargers, the charging start signal, generating a charging state signal from the other chargers, receiving, by the first charger, the charging state signal and determining the amount of supplied power of the first charger.

Abstract: The present invention relates to a position recognition method comprising the steps of: measuring a space in a first direction by means of at least one measurement device provided in a vehicle; recognizing a first marker by means of the measurement means; computing first positional information of the vehicle; acquiring map information; and specifying comprehensive positional information of the vehicle, wherein the first marker includes a coordinate value of the first marker, the first positional information is a coordinate value of the vehicle computed through recognition of the first marker, and the step of specifying the comprehensive positional information combines the first positional information of the vehicle with the map information.
