Abstract: A method for controlling an exhaust after-treatment system connected to a diesel engine via a gas passage and having a diesel oxidation catalyst (DOC) and a “diesel-exhaust-fluid” (DEF) injector arranged downstream of the DOC and upstream of a selective catalytic reduction catalyst (SCR) includes detecting a flow of exhaust gas emitted by the engine into the gas passage. The method also includes detecting a level of nitrogen oxides (NOx) in the exhaust gas downstream of the SCR. The method additionally includes activating the DEF injector for a period of time to reduce the level of NOx to a predetermined NOx value. Furthermore, the method includes regulating an injection of fuel upstream of the DOC to clean the DEF injector via a stream of superheated exhaust gas if the period of time used to reduce the level of NOx to the predetermined NOx value is greater than a predetermined threshold value.

Abstract: An exhaust treatment system to treat exhaust gas includes a particulate filter configured to trap soot contained in the exhaust gas, and a pressure sensor that outputs a pressure signal indicative of a pressure differential of the particulate filter. A soot mass module is configured to determine a soot mass indicative of an amount of soot stored in the particulate filter based on the pressure differential. The soot mass is selectively determined according to a first soot model or a second soot model. An adaptation soot load module corrects the first soot model based on the second soot model such that the first soot model is adapted to the second soot model. A frequency regeneration module determines an actual rate at which the first soot model is corrected. The frequency regeneration module further determines the particulate filter is excessively regenerated based on the actual rate and a threshold.

Abstract: Aspects of the disclosure include degas equipment and degassing process schemes for providing high throughput extraction of battery cell formation gas. An exemplary method can include loading a battery cell in a sampling chamber of a degas station and creating an opening in the battery cell to release formation gas. A first portion of the formation gas can be routed to a collection chamber of the degas station while the formation gas is prevented from venting. After routing the first portion of the formation gas to the collection chamber, a second portion of the formation gas can be vented until degassing is complete. The first portion of the formation gas can be diluted with a dilution fluid and the diluted first portion of the formation gas can be routed to a cell quality control gas manifold configured to measure battery cell formation gas compositions.

Abstract: A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to be filled with a gas. The quality control system includes a computational system including a processor and a memory, a manifold defining a passageway extending between an inlet port for receiving the gas and an outlet port, and at least one sensor in electronic communication with the computational system. The sensor is arranged to measure a physical property of the gas and transmit a signal to the computational system corresponding to the physical property of the gas. The computational system analyzes the physical property of the gas, accesses a threshold value corresponding to the physical property, compares the physical property to the threshold value, and assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.

Abstract: A method for fabricating an anode for a lithium ion battery cell is described and includes forming a solid electrolyte interface (SEI) layer on a raw anode prior to assembly into a battery cell by applying a first SEI-generating electrolyte to the raw anode to form a first intermediate anode, applying a second SEI-generating electrolyte to the first intermediate anode to form a second intermediate anode, and applying a third SEI-generating electrolyte to the second intermediate anode to form a cell anode, wherein the cell anode includes the raw anode having the SEI layer. Thus, a cell anode is formed by sequentially applying SEI-generating electrolytes to a raw anode to form the cell anode with an SEI layer, and a lithium ion battery cell is formed by assembling the cell anode into a cell pack, with a cathode, and a separator, and adding a cell electrolyte prior to sealing.
