Vehicle systems and methods are provided for preheating an aftertreatment system prior to engine ignition. A method involves obtaining a first measurement indicative of a current temperature associated with the aftertreatment system, obtaining a second measurement indicative of a current state of an energy source coupled to a heating element integrated with the aftertreatment system, determining an amount of electrical energy to be applied to the heating element based at least in part on a difference between the current temperature associated with the aftertreatment system and a target temperature for the aftertreatment system, and automatically enabling current flow from the energy source to the heating element prior to ignition of the engine for a duration of time in a manner that is influenced by the amount of electrical energy to be applied to the heating element and the current state of the energy source.
A method of preheating an aftertreatment system downstream of an engine of a vehicle prior to ignition of the engine, the method comprising:
A vehicle system comprising:
A non-transitory computer-readable medium comprising executable instructions that, when executed by a processor, cause the processor to provide an aftertreatment system preheating service configurable to:
