    Abstract: A palladium-only (i.e., platinum free) oxidation catalyst body is used to oxidize carbon monoxide and hydrocarbons in the exhaust stream of a diesel engine powered vehicle, which is operated at a fuel-lean air-to-fuel ratio (A/F) for much of the time it powers a vehicle. Periodically, a recent history of the temperatures of the exhaust gas at the inlet to the palladium oxidation catalyst body is prepared in a computer control module. And a recent history of the A/F of the operating engine is considered. These temperature and A/F values are then used in determining whether the engine should be temporarily operated in a fuel-rich or stoichiometric A/F mode to provide an exhaust gas composition suitable for rejuvenation of the palladium by reducing its oxide formed during lean operation of the engine.

    Abstract: Presented are control systems for operating rechargeable electrochemical devices, methods for making/using such systems, and motor vehicles with intelligent battery pack charging and charging behavior feedback capabilities. A method of operating a rechargeable battery includes an electronic controller receiving battery data from a battery sensing device indicative of a battery state of charge (SOC). Using this battery data, the controller determines a number of low SOC excursions at which the battery SOC is below a predefined low SOC threshold and a number of high SOC excursions at which the battery SOC exceeds a predefined high SOC threshold. The controller then determines if the number of low SOC excursions exceeds a predefined maximum allowable low excursions and/or the number of high SOC excursions exceeds a predefined maximum allowable high excursions. If so, the controller responsively commands a resident subsystem to execute a control operation that mitigates degradation of the rechargeable battery.
