  • Publication number: 20150042288
    Abstract: A vehicle 10 according to an embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. In a state where the connector 21 of the electric power cable 20 is connected with the inlet of the vehicle 10, an electric power is discharged/supplied from the vehicle electric storage device 11 to an external electric load (e.g., external electric storage device 41). Further, the vehicle electric storage device 11 is capable of being charged by the external power supply 50 through the electric power cable 20. A control device 12 of the vehicle 10 obtains/detects a permissible current value of the electric power cable 20, based on a specific signal (control pilot signal) which is transmitted through a CPLT terminal of the connector 21 before it starts the discharge to the external electric load from the vehicle electric storage device 11.

  • Publication number: 20140327408
    Abstract: A vehicle 10 according to the embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. From the HEMS 40 to the vehicle 10, a request for charge to charge an electric storage device 11 and a request for discharge to allow an external electric load to use an electric power of the electric storage device 11 are transmitted. When a request is changed from the request for charge to the request for discharge, or vice versa, the vehicle 10 realizes a charge-discharge stop state in which neither a charging operation nor a discharging operation is performed without directly changing from the charging operation to the discharging operation, or vice versa.

  • Patent number: 8428803
    Abstract: An EV priority switch is configured to allow a user to request a change between an EV priority mode and an HV mode. If an SOC of a power storage device is less than a first threshold value when the change to the HV mode is requested from the EV priority switch during the EV priority mode, an ECU changes the running mode to attain the HV mode and controls the SOC to be close to the SOC at the moment of a request for the change to the HV mode. If the SOC is greater than or equal to the first threshold value, the ECU maintains the EV priority mode. If the SOC reaches a second threshold value less than the first threshold value, the ECU forcefully changes the running mode to attain the HV mode.

  • Patent number: 8297391
    Abstract: First and second converters are connected in parallel to positive and negative lines, respectively. When a required power is smaller than a reference value, an ECU controls the first and second converters such that one of the first and second converters operates and the other stops. When the required power is equal to or larger than the reference value, the ECU controls the first and second converters such that both the first and second converters operate.
