Publication number: 20240166073Abstract: A system is provided for performing an automated power charging process for one or more electric vehicles using a processor. Included in the processor is a charge controller that calculates a capacity of a power grid system by communicating with the power grid system via a network, and a power demand level of the one or more electric vehicles to satisfy one or more mission requirements of each electric vehicle. The power demand level of the one or more electric vehicles is compared with the capacity of the power grid system. In response to the comparison, at least one charging mode is selected from an override mode and an internal combustion engine mode for performing the automated power charging process. The charge controller automatically charges the one or more electric vehicles based on the selected at least one charging mode.Type: ApplicationFiled: January 29, 2024Publication date: May 23, 2024Inventors: Jennifer K.

Patent number: 11280283Abstract: An engine control system and method includes sensing the quality of fuel in the engine relative to emissions, by for example sensing the level of an emission related constituent, such as sulfur. A fuel quality sensor detects a fuel quality of a fuel, such as the sulfur level the fuel, and provides a signal in response to the fuel quality. The engine control system also includes a navigation device to determine whether an engine is located in a regulated or non-regulated region. The engine control system receives the signal and controls engine operation by, for example, enabling or disabling one or more engine algorithms to improve performance of the engine based on the fuel quality signal or, in other embodiments, the combination of the fuel quality and the location of the engine.Type: GrantFiled: April 10, 2018Date of Patent: March 22, 2022Assignee: CUMMINS INTELLECTUAL PROPERTY, INC.Inventor: Jennifer K.

Publication number: 20220009472Abstract: A system is provided for performing an automated electrification operation for an electric vehicle (102) using a processor (122). An electrification controller (126) communicates with a model generation unit (128). The model generation unit (128) generates a model representative of a power consumption trend of the electric vehicle (102). The electrification controller (126) sets a target power margin for the electric vehicle (102) based on the model such that the target power margin is close to a minimum state-of-charge (SOC) threshold of an energy storage supply (124) of the electric vehicle (102). The target power margin represents a difference between the minimum SOC threshold and an ending power level of the energy storage supply (124) after completion of a mission associated with the electric vehicle (102). The processor (122) performs the automated electrification operation for the electric vehicle (102) based on the target power margin.Type: ApplicationFiled: November 9, 2018Publication date: January 13, 2022Inventors: Martin T. Books, Jennifer K. Light-Holets

Patent number: 10538237Abstract: A hybrid electric vehicle system comprises an internal combustion (IC) engine and an electric engine providing power to a drive shaft of the vehicle. The IC engine receives a fuel from a fuel tank. Exhaust gases from the IC engine are treated at an exhaust treatment apparatus including a reagent tank containing a reagent. A controller monitors a quality of the fuel in the fuel tank and the reagent in the reagent tank and if needed, initiates fuel degradation reduction event or a reagent degradation reduction event. These events can include running the IC engine even if a battery supplying power to the motor is not discharged. The fuel degradation reduction event includes dosing the fuel tank with an antioxidant to reduce the rate of degradation of the fuel.Type: GrantFiled: November 20, 2017Date of Patent: January 21, 2020Assignee: Cummins Inc.Inventors: Jennifer K.
