Abstract
Controlling electric vehicle (EV) charging operation by controlling capturing, from a pilot line communicatively linking an EV with an EV charging apparatus, at least one signal of a pulse width modulated (PWM) signal or power line communication (PLC) signal indicating EV charging session information associated with charging the EV by the charging apparatus; determining, from session success information from a controller of the charging apparatus, whether to analyze the EV charging session information; and when the session success information is determined to not indicate successful completion of an EV charging session, extracting the EV charging session information from the at least one signal according to Internet protocol layer, and analyzing the extracted EV charging session information to determine a marginal operating condition or a failure condition associated with an EV charging session.
