Patent ID: 8860366

Claim:
An apparatus for connecting an electric vehicle to an electrical socket and for selectively receiving and delivering either level I voltage or level II voltage, comprising: a first socket connector configured to couple with the electrical socket providing either level I voltage or level II voltage; a power conduit having a first end connected to the first socket connector and configured to convey a voltage from the electrical socket to the electric vehicle, the power conduit configured to deliver either the level I voltage or the level II voltage; a relay placed inline with the power conduit and configured to control voltage along the power conduit; a control circuit connected to the power conduit and configured to generate signals corresponding to the voltage along the power conduit, wherein the signals indicate whether the voltage is the level I voltage or the level II voltage; a switch connected to the power conduit and the relay, the switch being configured to be controlled by the control circuit in order to provide the level I or the level II voltage to the electric vehicle depending on whether the control circuit indicates the voltage is the level I voltage or the level II voltage; a vehicle connector connected to a second end of the power conduit and configured to connect to the electric vehicle to provide one of the level I voltage and the level II voltage; a processor connected to the control circuit and configured to receive signals from and send signals to the control circuit; a voltage monitor connected to the processor; and a display connected to the processor, wherein the level I voltage comprises a nominal 120 Volts A/C and the level II voltage comprises a nominal 240 Volts A/C.
