Abstract: The present disclosure provides a method for operating a three-way catalyst system at high temperatures. The method includes passing a high-temperature exhaust stream exiting an engine over a thermally stable three-way catalyst system including a metal oxide support; two or more catalytically active metals disposed on the support; and a porous metal oxide coating disposed on one or more exposed surfaces of the support. At least one of the catalytically active metals may be platinum (Pt). The method further includes reducing an amount of the nitrogen oxides (NOx), carbon monoxide (CO), and non-methane hydrocarbons (HCs) in an effluent stream exiting the thermally stable three-way catalyst system so that the effluent stream has a combined amount of nitrogen oxides (NOx) and non-methane hydrocarbons (HCs) of less than or equal to about 30 mg/mile and less than or equal to about 0.5 g/mile of carbon monoxide (CO).

Abstract: A vehicle includes an electric motor and a battery operable to provide electrical power to the electric motor. The battery system includes a first battery pack and a second battery pack. The first battery pack has a relatively high power density, and the second battery pack has a relatively high energy density. An electronic controller determines a remaining driving range of the first battery pack, and a remaining driving range of the second battery pack. The vehicle has a human-machine interface (HMI) operatively connected to the electronic controller and configured to indicate the remaining driving range of the first battery pack and the remaining driving range of the second battery pack. The controller executes a method of monitoring the battery system.
