A method performed by an interface system that provides payment information to electric vehicle charging networks, the method comprising: automatically determining whether a charging station is within a predetermined distance to an electric vehicle, including tracking, by a mobile application provided by the interface system, a location of the electric vehicle to one or more specific charging stations; if the charging station is within a predetermined distance, automatically providing payment information to a charging network that provides the charging station, including: identifying, by the interface system, the charging network (140; 210, 220, 230) associated with the charging station, calling an application programming interface provided by the charging network to retrieve information identifying a payment protocol associated with the charging network, retrieving payment information for the electric vehicle that satisfies the payment protocol, and automatically providing the retrieved payment information from the interface system to the charging network via the payment protocol; and before providing the payment information to the charging network, determining the electric vehicle is not registered with the charging network, identifying a registration protocol associated with the charging network, capturing information for the electric vehicle that is identified by the registration protocol, registering the electric vehicle with the charging network by providing the captured information to the charging network. automatically determining whether a charging station is within a predetermined distance to an electric vehicle, including tracking, by a mobile application provided by the interface system, a location of the electric vehicle to one or more specific charging stations; if the charging station is within a predetermined distance, automatically providing payment information to a charging network that provides the charging station, including: identifying, by the interface system, the charging network (140; 210, 220, 230) associated with the charging station, calling an application programming interface provided by the charging network to retrieve information identifying a payment protocol associated with the charging network, retrieving payment information for the electric vehicle that satisfies the payment protocol, and automatically providing the retrieved payment information from the interface system to the charging network via the payment protocol; and before providing the payment information to the charging network, determining the electric vehicle is not registered with the charging network, identifying a registration protocol associated with the charging network, capturing information for the electric vehicle that is identified by the registration protocol, registering the electric vehicle with the charging network by providing the captured information to the charging network. identifying, by the interface system, the charging network (140; 210, 220, 230) associated with the charging station, calling an application programming interface provided by the charging network to retrieve information identifying a payment protocol associated with the charging network, retrieving payment information for the electric vehicle that satisfies the payment protocol, and automatically providing the retrieved payment information from the interface system to the charging network via the payment protocol; and before providing the payment information to the charging network, determining the electric vehicle is not registered with the charging network, identifying a registration protocol associated with the charging network, capturing information for the electric vehicle that is identified by the registration protocol, registering the electric vehicle with the charging network by providing the captured information to the charging network.
