Patent number: 11891001Abstract: A vehicle power supply system, being mounted on a vehicle, includes: a main power supply system including a main low-voltage power supply and a normal load; and a backup power supply system including a backup low-voltage power supply and an emergency important load and connected to the main power supply system. A backup power supply control device of the backup power supply system is configured to execute a backup low-voltage power supply state estimation processing, and output a signal indicating that the backup low-voltage power supply is in a state allowing supplying electric power for operating the emergency important load based on an estimation result of the backup low-voltage power supply state estimation processing, in a case in which the state of the vehicle does not satisfy a predetermined condition.Type: GrantFiled: July 11, 2022Date of Patent: February 6, 2024Assignee: HONDA MOTOR CO., LTD.Inventors: Kazuki Toyooka, Yuhei Matsuo, Hayahito Ukai, Yasuhiro Ikeda, Hironori Deno

Publication number: 20230001868Abstract: A vehicle power supply system, mounted on a vehicle including an internal combustion engine, includes: a main power supply system including a main low-voltage power supply; and a backup power supply system including a backup low-voltage power supply. A starter motor that starts the internal combustion engine is connected to the main power supply system. At least one of a vehicle control device, configured to control the main power supply system, the backup power supply system, the internal combustion engine and the starter motor, and a backup power supply control device of the backup power supply system is configured to execute an abnormality determination processing of determining whether an abnormality occurs in the main power supply system, and does not execute the abnormality determination processing when the starter motor is in operation, or determines that no abnormality occurs in the main power supply system in the abnormality determination processing.Type: ApplicationFiled: June 29, 2022Publication date: January 5, 2023Applicant: HONDA MOTOR CO., LTD.Inventors: Kazuki TOYOOKA, Yuhei MATSUO, Hayahito UKAI, Yasuhiro IKEDA, Hironori DENO

Patent number: 11522371Abstract: A power-supply control device includes a processor that performs a battery abnormality recognizing process and a control process. In the control process, the processor performs a first power-supply control operation of enabling supply of electric power from a secondary battery to a first load by a first connection circuit and supply of electric power from a secondary battery to a second load by a second connection circuit and, when an abnormality of the secondary battery is recognized in the battery abnormality recognizing process, performs a second power-supply control operation of controlling the first relay into a disconnected state to stop the supply of electric power from the secondary battery to the first load by the first connection circuit and maintain the supply of electric power from the secondary battery to the second load by the second connection circuit.Type: GrantFiled: March 4, 2021Date of Patent: December 6, 2022Assignee: HONDA MOTOR CO., LTD.Inventors: Satoshi Sekiguchi, Takeshi Itagaki, Kazutaka Yoshimura, Kosuke Murata, Hironori Deno, Yuto Fukusho
