Patent number: 10220835Abstract: In a vehicle, a first energy storage device has a first direct current (DC) operating voltage; and a second energy storage device has a second DC operating voltage. The second DC operating voltage is greater than or less than the first DC operating voltage the first DC operating voltage. A switch is connected between the first and second energy storage devices. A fault diagnostic module, while an internal combustion engine of the vehicle is shut down, diagnoses that a fault is present when a voltage of the first energy storage device is less than a predetermined DC voltage. The predetermined DC voltage is less than the first DC operating voltage. A switch control module closes the switch when the fault is diagnosed. A starter control module, when the fault is diagnosed, applies power to a starter from the second energy storage device via the switch.Type: GrantFiled: March 1, 2017Date of Patent: March 5, 2019Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Scott W.

Patent number: 9828963Abstract: A method for fault-tolerant coasting control of a powertrain system having an engine and a first energy storage system (ESS) includes receiving a real impedance value of the first ESS from a frequency analyzer device at a calibrated frequency while the engine is running, and comparing the real impedance value to a calibrated impedance. A coasting maneuver is enabled allowing the engine to turn off above a threshold speed when the real impedance value is less than the calibrated impedance. The method may include starting the engine using a second ESS in parallel with the first ESS to exit the coasting maneuver when the real impedance value exceeds the calibrated impedance. Subsequent execution of the coasting maneuver may be prevented as long as the real impedance value exceeds the calibrated impedance. A powertrain system includes the engine, starter motor, rechargeable ESS, frequency analyzer, and controller.Type: GrantFiled: November 24, 2015Date of Patent: November 28, 2017Assignee: GM Global Technology Operations LLCInventors: Robert S.

Patent number: 8573513Abstract: An inlet check valve assembly with flame arresting feature. An internal flame arresting feature utilizes a flame arrester body attached to a valve member which protrudes into the valve throat. An external flame arresting feature utilizes a hood concentrically disposed relative to the valve member. The flame arresting feature is configured relative to movement of the valve member with respect to the throat such that fluidic communication between the fuel fill pipe and the fuel tank is limited to less than the minimum flame propagation distance of the fuel and air mixture in which a combustible mixture may exist in the fuel fill pipe, whereby any flame front in the fuel fill pipe will quench thereat before reaching the fuel tank.Type: GrantFiled: May 27, 2011Date of Patent: November 5, 2013Assignee: GM Global Technology Operations LLCInventors: Vincent J.

Publication number: 20130052509Abstract: A lithium ion battery in which electrically-non conducting ceramic particles are interposed between the anode and cathode to enforce separation between them and prevent short circuits is described. The particles, preferably equiaxed or monodisperse, may be generally uniformly dispersed in a non-aqueous gelled or high viscosity electrolyte. The electrolyte may be applied to one or both of the anode and cathode in suitable thickness to deposit the particles with the electrolyte and form a layered composite with substantially uniformly spaced particles suitable for holding the opposing anode and cathode faces in spaced-apart relation. The thickness of the applied electrolyte layer will be selected to enable deposition of the particles substantially as a fractional monolayer, a monolayer, or a multilayer as required for the application.Type: ApplicationFiled: August 25, 2011Publication date: February 28, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Ion C.
