Patent number: 11794607Abstract: An electrically powered vehicle includes a plurality of batteries and a plurality of DC to DC converters, each coupled to a respective battery of the plurality of batteries. Each DC to DC converter transfers power from a respective battery to a common DC bus. The common DC bus is coupled to a plurality of inverter circuits that convert the DC power to AC power. A plurality of electric motors receive power from the plurality of inverter circuits to propel the vehicle. During a regenerative event, the DC to DC converters can transfer power from the motors back to the batteries. In response to the failure of a battery, the DC to DC converters can isolate the remainder of the system from the failure.Type: GrantFiled: February 2, 2021Date of Patent: October 24, 2023Assignee: Wisk Aero LLCInventors: Geoffrey Alan Long, Michael John Burgart

Patent number: 11787307Abstract: A MPU controls a changeover switch, which is an FET switch that connects a main battery and a sub-battery having a low rated voltage. The changeover switch is set to an ON state in a case where a potential difference, which is a difference between a voltage of the main battery and a voltage of the sub-battery, is equal to or greater than a positive first predetermined value. A PWM signal is output to a driver to cause the changeover switch to be in a half-ON state in a case where the potential difference is less than the first predetermined value and is greater than a second predetermined value equal to or less than 0. The changeover switch is set to an OFF state in a case where the potential difference is equal to or less than the second predetermined value.Type: GrantFiled: October 6, 2021Date of Patent: October 17, 2023Assignee: Yazaki CorporationInventor: Atsushi Takahashi

Patent number: 11780438Abstract: A motor vehicle having a combustion engine for vehicle propulsion can be automatically stopped when engine propulsion is not needed, such as during a gliding condition when the vehicle is coasting down to a slower speed (e.g., stopping) or down an incline. The engine is automatically restarted as needed. To ensure a capacity of a battery or other electrical storage device to support nominal operation of electrical loads (including a starter motor for restarting the engine) during an Auto Stop event, predicted future states of a vehicle battery are determined using a battery state of function (SOF) in response to load transients that may need to be supported.Type: GrantFiled: August 31, 2022Date of Patent: October 10, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Mark Eifert, Pankaj Kumar
