1. A method, comprising:
receiving, by a controller, information indicative of a temperature of an aftertreatment system of a vehicle and a power output of an engine of the vehicle;
comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold;
comparing, by the controller, the power output to a power output threshold;
responsive to the comparisons indicating that the temperature of the aftertreatment system is below the temperature threshold and the power output of the engine is below the power output threshold, engaging an aftertreatment system heater;
responsive to the comparisons indicating that the temperature of the aftertreatment system is below the temperature threshold and the power output of the engine is above the power output threshold, reducing a power consumption from the aftertreatment system heater; and
responsive to the comparisons indicating that the temperature of the aftertreatment system is above the temperature threshold and the power output of the engine is above the power output threshold, disengaging the aftertreatment system heater.
