    Abstract: An aftertreatment system including a method which provides a selective catalytic reduction (SCR) catalyst disposed in an exhaust stream of an engine; determines that an ammonia pre-load condition for the SCR catalyst is present; determines a first amount of ammonia pre-load in response to the ammonia pre-load condition; injects an amount of ammonia or urea into the exhaust stream in response to the first amount of ammonia; and adsorbs a second amount of ammonia onto the SCR catalyst in response to injecting an amount of ammonia or urea, where the second amount of ammonia is either the injected amount of ammonia or an amount of ammonia resulting from hydrolysis from the injected amount of urea.

    Abstract: Systems and methods are disclosed that include an exhaust gas stream produced by an engine and an aftertreatment system including an SCR catalyst element receiving at least a portion of the exhaust gas stream. An exhaust outlet flow path has an inlet fluidly coupled to the exhaust gas stream at a position downstream of at least a portion of the SCR catalyst element that bypasses at least a portion of exhaust gas stream to provide for compositional measurement of the exhaust gas with a compositional sensor located downstream of a diagnostic catalyst positioned in the exhaust outlet flow path.

    Abstract: Systems and methods for determining state of health (SOH) of a battery. For example, a method includes conditioning the battery by determining an initial state of charge of the battery; charging the battery from the initial state of charge to a first target state of charge via a predetermined multi-stage charging sequence; and determining SOH of the battery by charging the battery from the first target state of charge to a second target state of charge at an ICA charging rate; acquiring a voltage vs. capacity (QV) data of the battery during charging of the battery from the first target state of charge to the second target state of charge; obtaining an incremental capacity (IC) data based on at least the acquired QV data; pre-processing the IC data; extracting an incremental capacity analysis (ICA) peak from the IC data; and determining the SOH of the battery based upon the ICA peak.
