Patent number: 10611258Abstract: A vehicle includes a low-voltage battery, a high-voltage battery, and a converter that decreases voltage provided from the high-voltage battery to the low-voltage battery. A system controller of the vehicle is programmed to use the converter, in a key-off cycle, to charge the low-voltage battery a calibrated number of times that the low-voltage battery drops below a predefined state-of-charge threshold, and send a wireless notification a subsequent time the low-voltage battery drops below the threshold. A notification is sent to a predefined contact address when a periodically computed state of charge of a low-voltage battery of a vehicle falls below a predefined threshold. Using a converter, voltage provided from a high-voltage battery of the vehicle to the low-voltage battery is decreased to charge the low-voltage battery responsive to receipt from the contact address of a response indicating approval of the charge.Type: GrantFiled: November 15, 2016Date of Patent: April 7, 2020Assignee: Ford Global Technologies, LLCInventors: David Anthony Symanow, Derek Hartl

Patent number: 10252622Abstract: A vehicle may include a battery and a controller programmed to set a bus voltage threshold such that during a next charging event a voltage of the battery achieves a desulfation value. The controller may set the bus voltage threshold in response to charge acceptance of the battery falling below a predetermined sulfation value. The controller may be programmed to lower the threshold such that the voltage of the battery falls below the desulfation value. The controller may lower the threshold in response to the charge acceptance exceeding the predetermined sulfation value during the event.Type: GrantFiled: October 13, 2016Date of Patent: April 9, 2019Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventor: David Anthony Symanow
