Publication number: 20230278447Abstract: A vehicle that supports rapid charge and normal charge and discharge includes an electrical load, a first power line, a second power line, a third power line, a first relay, a second relay, a first current sensor, a second current sensor, and an electronic control unit. The electronic control unit of the vehicle is configured to measure a current using a detection value from the second current sensor with the first relay controlled to an open state and with the second relay controlled to a closed state when the normal charge and discharge is executed. The electronic control unit is configured to measure a current using a detection value from the first current sensor with the first relay controlled to a closed state and with the second relay controlled to an open state when the rapid charge is executed.Type: ApplicationFiled: December 6, 2022Publication date: September 7, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke SHIMOGAKI

Publication number: 20230128750Abstract: A vehicle is configured to perform charging/discharging between an EVPS and the vehicle via a vehicle inlet. The vehicle includes an ECU that controls charging/discharging of the vehicle, and a control signal circuit including at least one control signal line connected between the vehicle inlet and the ECU. The control signal circuit includes a compatible circuit for ensuring compatibility of a control signal transmitted through the at least one control signal line between the EVPS and the ECU, and an isolating element of capacitive coupling type or magnetic coupling type electrically isolating the compatible circuit from the ECU.Type: ApplicationFiled: October 20, 2022Publication date: April 27, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yusuke Shimogaki

Patent number: 11444565Abstract: A power device includes: a DC voltage output circuit that generates a DC internal power voltage from external supply power; a capacitor that is connected to the internal power voltage; and a voltage supply control circuit that monitors a voltage level of the internal power voltage and that, when detecting a drop in the internal power voltage, cuts off supply of the internal power voltage. The power device supplies internal power to a load. The power device supplies, to a first load that is a part of the load, the internal power voltage, and supplies, to a second load that is a load other than the first load, the internal power voltage via the voltage supply control circuit.Type: GrantFiled: July 11, 2019Date of Patent: September 13, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Satoshi Furukawa, Yusuke Shimogaki

Patent number: 11293997Abstract: A diagnostic apparatus includes a control device and an extension device connectable to the control device. The control device includes one or more cutoff blocks that switch between allowing and cutting off power supply to a load, a first diagnostic pulse generator that generates a diagnostic signal indicating that the power to the load is to be cut off, a first cutoff diagnosing device that detects a supply voltage to the load, and an extension device detector that determines whether the extension device is connected to the control device. The extension device includes a second diagnostic pulse generator that generates a diagnostic signal, and a second cutoff diagnosing device that detects a supply voltage to the load.Type: GrantFiled: April 17, 2018Date of Patent: April 5, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Taro Kishibe, Hideyuki Kishida, Yusuke Shimogaki

Patent number: 10978987Abstract: A motor drive device includes: an inverter circuit; a drive circuit which receives voltage supplied from a control power source; a first cutoff circuit which cuts off voltage supply from the control power source to the drive circuit; a second cutoff circuit connected between the first cutoff circuit and the drive circuit; a voltage detection circuit which detects a detection voltage corresponding to the voltage supplied from the control power source and which is capable of changing the detection voltage; a comparison circuit which, upon determination that the detection voltage is not within a predetermined range, cuts off the first cutoff circuit; and a diagnosis circuit which diagnoses the first cutoff circuit. The diagnosis circuit causes the comparison circuit to cut off the first cutoff circuit, diagnoses the first cutoff circuit, and upon diagnosing the operation of the first cutoff circuit as being abnormal, cuts off the second cutoff circuit.Type: GrantFiled: April 17, 2018Date of Patent: April 13, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Tomoya Hosokawa, Taro Kishibe, Yusuke Shimogaki
