1. A vehicle comprising:

  • a power connector configured to mate with an electrical power grid receptacle and receive a grid power therefrom;

    a heating and cooling system electrically connected to the power connector to receive grid power therefrom and configured to modify a temperature in a cabin of the vehicle;

    a temperature control loop configured to selectively activate and control the heating and cooling system; and

    a controller configured to;

    receive a first input signal comprising a desired vehicle activation time;

    receive a second input signal comprising a starting vehicle cabin temperature and a desired vehicle cabin temperature;

    determine a temperature control loop activation time based on the first and second input signals, the temperature control loop activation time being a time prior to the desired vehicle activation time;

    transmit an activation signal to the temperature control loop at the temperature control loop activation time to activate the heating and cooling system;

    determine if the vehicle is activated at the desired vehicle activation time or within a pre-determined time thereafter; and

    if the vehicle is not activated at the desired vehicle activation time or within the pre-determined time thereafter, then transmit a deactivation signal to the temperature control loop to deactivate the heating and cooling system.
