1. A device for providing adaptive charging of an electric vehicle (EV), the device comprising:
a memory; and
at least one processor configured for:
receiving a set of parameters of an aggregate power waveform carried on a power line from a set of sensors;
receiving a set of relationships between a set of power signatures and a set of power sources, wherein the set of power signatures includes respective sets of parameters for each power signature in the set of power signatures;
determining, using the set of parameters and the set of power signatures, a subset of the set of power signatures represented in the set of parameters;
identifying, using the subset of the set of power signatures and the set of relationships between the set of power signatures and the set of power sources, a subset of the set of power sources contributing to the aggregate power waveform;
determining a variance between a set of parameters for a power signature in the set of power signatures and the set of parameters of the aggregate power waveform;
identifying the power signature in the set of power signatures as represented in the set of parameters of the aggregate power waveform;
updating, to include the determined variance, the set of parameters for the power signature in the set of power signatures; and
controlling, responsive to identifying identified subset of the set of power sources, a charging circuit, wherein the charging circuit is configured to be electrically coupled between the power line and the EV.
