Patent number: 11951843Abstract: A vehicle power supply device converts power from high voltage to low voltage by selectively connecting a predetermined power storage element group to a low voltage electric load from a high voltage power supply formed by connecting power storage elements in series. A leakage current from the high voltage power supply is measured during the dead time period when the power storage element group is not connected to the low voltage electric load. When the value exceeds a predetermined value, the connection between the power storage element group and the low-voltage electric load is interrupted, so that electric shock is prevented.Type: GrantFiled: December 7, 2020Date of Patent: April 9, 2024Assignee: IMASEN ELECTRIC INDUSTRIAL CO., LTD.Inventors: Daisuke Makio, Koichi Yamanoue

Patent number: 11945313Abstract: A vehicle power supply device converts power from high voltage to low voltage by selectively connecting a predetermined power storage element group to a low voltage electric load from a high voltage power supply formed by connecting power storage elements in series. A leakage resistance from the high voltage power supply to the ground is measured when the high voltage circuit is cut by the cutoff means placed between the high voltage power supply and the high-voltage load device. When the value less than a predetermined value, the connection between the high voltage power supply and the low-voltage load device is interrupted, so that electric shock is prevented.Type: GrantFiled: March 8, 2021Date of Patent: April 2, 2024Assignee: IMASEN ELECTRIC INDUSTRIAL CO., LTD.Inventors: Daisuke Makio, Koichi Yamanoue

Publication number: 20230391201Abstract: In a vehicle power supply device mounted on a vehicle and obtaining a low voltage power supply from a high voltage power supply via a step-down means, electric shock to the human body is prevented without using an insulating means such as a transformer. A vehicle power supply device converts power from high voltage to low voltage by selectively connecting a predetermined power storage element group to a low voltage electric load from a high voltage power supply formed by connecting power storage elements in series. A leakage current from the high voltage power supply is measured during the dead time period when the power storage element group is not connected to the low voltage electric load. When the value exceeds a predetermined value, cutting off the power supply from the high-voltage power supply to the high-voltage load device, so that electric shock is prevented.Type: ApplicationFiled: September 17, 2021Publication date: December 7, 2023Inventors: Daisuke MAKIO, Koichi YAMANOUE
