1. A plug-in electric vehicle comprising:

  • an electric motor;

    a traction battery configured to power the electric motor during a driving operation of the plug-in electric vehicle;

    a charging plate including at least a secondary coil of an inductive charging system; and

    a diode including an anode connected directly to the charging plate and a cathode connected to the traction battery;

    wherein the secondary coil of the charging plate is configured to interact with a stationary primary coil of the inductive charging system when the plug-in electric vehicle is suitably positioned relative to the stationary primary coil;

    wherein the inductive charging system is configured to inductively charge the traction battery when the secondary coil interacts with the stationary primary coil; and

    wherein the diode enables a current flow from the secondary coil of the charging plate to the traction battery when the plug-in electric vehicle is suitably positioned relative to the stationary primary coil, but prevents a current flow from the traction battery to the charging plate during driving.
