Abstract

A system for determining identity information corresponding to an electrically operable machine is disclosed, where the electrically operable machine receives electricity from a power supply port. The system includes at least one sensor to generate a signal indicative of the electricity being drawn by the electrically operable machine from the power supply port. The system further includes a controller communicatively coupled to the at least one sensor and configured to determine the identity information corresponding to the electrically operable machine based on one or more electrical characteristics of the signal sensed by the at least one sensor. Method and non-transitory computer readable media for determining the identity of the electrically operable vehicle are also disclosed. Moreover, a system for controlling charging of a vehicle that is operated at least partially by the electricity is also disclosed.
