  • Publication number: 20240109433
    Abstract: A vehicle includes a high-voltage battery, a motor generator, a high-voltage system wire configured to electrically couple the high-voltage battery and the motor generator, a system main relay configured to turn ON or OFF electric coupling between the high-voltage battery and the motor generator on the high-voltage system wire, an atmospheric pressure sensor configured to detect an atmospheric pressure at a position of the vehicle, and a control device. The control device includes one or more processors, and one or more memories coupled to the one or more processors. The one or more processors are configured to execute a process including performing SMR-OFF control for controlling the system main relay to turn OFF when the system main relay is ON and the atmospheric pressure detected by the atmospheric pressure sensor is lower than a first atmospheric pressure threshold.

  • Publication number: 20240092216
    Abstract: A charging prediction system includes vehicles, a charging station, and a control device including one or more processors and one or more memories. The one or more processors are configured to execute a process. The process includes accumulating, in a storage device, record data that is actual data on a charged vehicle ratio for a first remaining traveling distance of each of the vehicles traveling along a specific traveling road. The process includes deriving, based on the record data, a predicted value of the charged vehicle ratio for each vehicle in a predetermined group including ones of the vehicles currently traveling along the specific traveling road. The process includes deriving a predicted waiting period that is a predicted value of a waiting period to a start of charging at the charging station based on the predicted values of the charged vehicle ratios.

  • Publication number: 20240034161
    Abstract: A vehicle charging and discharging system to be applied to an electric vehicle includes a rectifier, an inverter, a relay, and a control processor. The rectifier is disposed on a charging path through which a battery of the electric vehicle is to be contactlessly charged from external equipment via a coil in the electric vehicle. The inverter is disposed on a first path from the battery to an electric power output terminal of the electric vehicle, the electric power output terminal allowing for output of electric power stored in the battery. The relay is disposed on a second path from the inverter to the coil. The control processor controls an operation state of the relay to allow the electric power stored in the battery to be contactlessly discharged to the external equipment via the inverter, the relay, and the coil on the second path.

  • Publication number: 20240034160
    Abstract: A vehicle charging system to be applied to an electric vehicle includes a rectifier, an inverter, first and second relays, and a control processor. The rectifier is disposed on a charging path. The inverter is disposed on a first power feeding path. The first and second relays are respectively disposed on the charging path and a second power feeding path. The control processor performs control that allows for: contactless charging via the charging path from external equipment; and first power feeding to an external device via the charging path and the first power feeding path from the external equipment, or second power feeding to the external device via the second power feeding path from the external equipment. The control processor controls operation states of the relays in accordance with power being supplied from the external equipment, power requested at a battery, and power necessary at the external device.
