1. An electrified vehicle assembly, comprising:
- a coolant circuit;
a resistor bank;
a controller configured to direct energy from an energy recovery mechanism into at least one component of the coolant circuit when an energy dissipation mode is activated, and configured to direct energy from the energy recovery mechanism into a battery of an electrified vehicle when the energy dissipation mode is not activated, the energy dissipation mode activated in response to a grade; and
the controller configured to direct energy from the energy recovery mechanism to the resistor bank when the energy dissipation mode is activated, the resistor bank cooled by ram airflow.

10. A method of dissipating energy within an electrified vehicle, comprising:
-
selectively activating an energy dissipation mode in response to a grade; generating an amount of energy from an energy recovery device, wherein the amount of energy is a first amount of energy; directing the amount of energy to at least one component of a coolant circuit of an electrified vehicle when the energy dissipation mode is activated; directing the amount of energy to a battery when the energy dissipation mode is not activated; generating a second amount of energy using the energy recovery device and directing the second amount of energy to a resistor bank when the energy dissipation mode is activated; and cooling the resistor bank with ram airflow. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
