Abstract
A system includes a first heater positioned in or proximate to an exhaust aftertreatment system in exhaust gas-receiving communication with an engine, a second heater positioned downstream of the first heater, and a controller coupled to the first and second heaters. The controller is structured to determine, based on information indicative of a temperature regarding the exhaust aftertreatment system, that the temperature is below a temperature threshold; receive information regarding a characteristic of a battery coupled to the first heater and the second heater; control the temperature regarding the exhaust aftertreatment system without using the first or second heaters in response to determining that the characteristic of the battery is below a first threshold; and control a temperature regarding the exhaust aftertreatment system using the first heater in response to determining that the characteristic of the battery is above the first threshold but below a second threshold.
