Abstract
An exhaust gas treatment system for an internal combustion engine is provided. The exhaust gas system includes an exhaust gas conduit, a generator, a vehicle electrical system, a primary energy storage device, a rechargeable secondary energy storage device, an electrically heated catalyst ('EHC') device, and a control module. The primary energy storage device is selectively connected to the generator. The primary energy storage device has a threshold state of charge ('SOC'). The rechargeable secondary energy storage device is selectively connected to the generator and the vehicle electrical system. The EHC device is in fluid communication with the exhaust gas conduit. The EHC device has an electric heater that is selectively connected the generator for receiving energy and a selectively activated catalyst that is heated to a respective light-off temperature.
