System and method of maintaining high voltage battery charging with detected auxiliary battery fault
Patent number: 10112487Abstract: A system using a computer to be configured to perform particular actions by virtue of having software, firmware, hardware, or a combination installed. One aspect includes a system, programmed to receive a fault signal from an auxiliary battery sensor. The system also determines if a low voltage set point is greater than the main battery voltage, and sends an open switch signal to a battery isolation switch if the low voltage set point is greater than the main battery voltage value. The system will send an auxiliary set point signal to an auxiliary battery charger to maintain a low voltage. The system will receive a current signal from an auxiliary battery sensor to indicate an auxiliary battery current value. The system also determines if the auxiliary battery current is above a maximum current value, and send a disable auxiliary battery maintenance signal to the auxiliary battery charger.Type: GrantFiled: April 18, 2017Date of Patent: October 30, 2018Assignee: Ford Global Technologies, LLCInventors: Josephine S. Lee, Cathleen Tistle, Jeff Raymond Mohr, James Brian Keyse, Jeremy L. Russell -

Patent number: 10093198Abstract: A method is provided for determining a lower voltage set-point, an upper voltage set-point, a temperature-dependent upper current set-point, a time limit value, and a lower current hysteresis threshold set-point based on a measured temperature of a battery. A charge current from a battery charging circuit is provided. If a charge voltage is above the lower voltage set-point and below the upper voltage set-point and the charge current exceeds the temperature-dependent upper current set-point, timer is started. If the timer reaches a time limit value while the charge current exceeds the temperature-dependent upper current set-point and the charge voltage is between the lower voltage set-point and the upper voltage set-point, the charge current is reduced.Type: GrantFiled: August 24, 2017Date of Patent: October 9, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Cathleen Tistle, Mark Eifert, Christopher Semanson

Patent number: 9828964Abstract: A auto-stop/start vehicle with an engine and a battery includes at least one controller that calibrates an engine auto-stop delay time based on a state of charge (SOC) of a battery. The calibrated engine auto-stop delay time increases as the SOC of the battery decreases, and decreases as the SOC of the battery increases. The controller further initiates shutdown of an engine upon expiration of the calibrated engine auto-stop delay time.Type: GrantFiled: July 26, 2016Date of Patent: November 28, 2017Assignee: Ford Global Technologies, Inc.Inventors: David Crist Gabriel, Cathleen Tistle

Publication number: 20160352120Abstract: A vehicle includes a traction battery, an auxiliary battery, a voltage converter selectively coupled with the traction battery and coupled with the auxiliary battery, an indicator, and a controller. The controller may be programmed to activate the indicator to indicate presence of a voltage on a high-voltage bus indicative of a current from the traction battery to the auxiliary battery during an ignition-off period in response to detecting an auxiliary voltage on a low-voltage bus less than a minimum voltage and a voltage on the high-voltage bus greater than a predetermined threshold.Type: ApplicationFiled: May 26, 2015Publication date: December 1, 2016Inventors: Karin Lovett, Cathleen Tistle, William David Treharne

Publication number: 20150331686Abstract: A symptom database may associate vehicle parameters indicative of vehicle issues with software updates correcting the issues. A diagnostic server may receive vehicle parameters from a vehicle responsive to vehicle generation of a diagnostic code, utilize the symptom database to identify a software update corresponding to an issue indicated by the vehicle parameters, and provide a response identifying the software update for automatic installation by the vehicle to correct the issue. A processor of a vehicle may send, to a diagnostic server responsive to vehicle generation of a diagnostic code, vehicle parameters including the diagnostic code and an identifier of the vehicle, receive, from the diagnostic server, a response identifying a software update corresponding to an issue indicated by the vehicle parameters, receive the software update responsive to the response identifying the software update, and automatically install the software update.Type: ApplicationFiled: May 15, 2014Publication date: November 19, 2015Applicant: Ford Global Technologies, LLCInventors: Peter Eric PETERSEN, Cathleen TISTLE
