Patent number: 11766927Abstract: A vehicle includes: a low voltage battery constituted by a lithium-ion battery, the low voltage battery supplying an electric power to an electric component mounted to a vehicle; a high voltage battery constituted by a lithium-ion battery, the high voltage battery having an output voltage higher than an output voltage of the low voltage battery; a first rotating electrical machine that operates by an electric power supplied from the high voltage battery, the first rotating electrical machine generating a torque for driving the vehicle; and a second rotating electrical machine for starting the engine. The second rotating electrical machine operates by an electric power supplied from the high voltage battery.Type: GrantFiled: June 1, 2020Date of Patent: September 26, 2023Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Yoshimasa Nishihiro, Masahiko Tahara, Masaharu Mochizuki, Takurou Hirano

Publication number: 20220242246Abstract: The power supply device includes a low voltage battery, a high voltage battery, a starter generator, a DC-DC converter, a changeover switch, and a controller. When an abnormality or a failure has occurred in the DC-DC converter, the controller controls the changeover switch to connect the starter generator to the other battery without via the DC-DC converter and controls the output of the starter generator corresponding to the connected other battery.Type: ApplicationFiled: June 1, 2020Publication date: August 4, 2022Applicants: JATCO Ltd, NISSAN MOTOR CO., LTD.Inventors: Yoshimasa NISHIHIRO, Masahiko TAHARA, Masaharu MOCHIZUKI, Takurou HIRANO
