Aftertreatment heater management for efficient thermal management

A method for decreasing harmful emissions from an engine system, comprising:

• determining, by a controller, whether the engine system is idling;
• in response to determining that the engine system is idling, determining, by the controller, whether a value regarding operation of the engine system is greater than a threshold value;
• in response to determining that the value is greater than the threshold value, determining, by the controller, whether a temperature associated with at least one of the engine system or an aftertreatment system is greater than a threshold temperature;
• and
• in response to determining that the temperature of the at least one of the engine system or the aftertreatment system is greater than the threshold temperature, disabling or at least partially disabling, by the controller, a heater coupled to the aftertreatment system.

An apparatus, comprising:

• a controller having a processing circuit comprising at least one memory having computer-executable instructions stored thereon that is coupled to at least one processor, the computer-executable instructions, when executed by at least one processor, causes the processing circuit to perform operations comprising:
• determining whether a value regarding operation of an engine system is greater than a threshold value;
• in response to determining that the value is greater than the threshold value, determining whether a temperature regarding at least one of the engine system or of an aftertreatment system coupled to the engine system is greater than a threshold temperature;
• and
• in response to determining that the temperature of the at least one of the engine system or of the aftertreatment system is greater than the threshold temperature, disabling or at least partially disabling a heater coupled to the aftertreatment system.
