Abstract: In one aspect, a cross-connect cable for charging an electric vehicle (EV) is provided. The cross-connect cable comprises wiring, first and second charging plugs, a sensor, and a controller. The wiring comprises power conductors and communication lines. The first and second charging plugs are electrically coupled to opposite ends of the wiring. The sensor is configured to measure a voltage of, and a current carried by, the power conductors. The controller is configured to determine whether the first and second charging plugs have been electrically connected to first charging port of a power source and a second charging port of the EV, respectively. The controller is further configured to initiate a charging session from the power source to the EV, and calculate, based the voltage and the current, energy delivered from the power source to the EV for the charging session.
