  • Patent number: 10259342
    Abstract: An overall loss L during non-execution of intermittent boosting (in ordinary boosting) is calculated from losses L1 and L2 of motors and a loss LC of a boost converter during non-execution of intermittent boosting. The overall loss L during execution of intermittent boosting is calculated from the losses L1 and L2 of the motors and the loss LC of the boost converter during execution of intermittent boosting. A minimum loss-time boosting voltage Vtmp at which the overall loss L provides a minimum loss Ltmp is set to a target voltage VH*. The boost converter is then controlled in a control state corresponding to the minimum loss-time boosting voltage Vtmp.

  • Patent number: 10259328
    Abstract: When connection of a charging gun is detected, a charging-control ECU wakes up, and turns on a power supply relay to activate a charging-communication ECU. The charging-control ECU subsequently actives a power-control computer by communicating therewith. The power-control computer closes an SMR, and closes a power supply switch to activate a monitoring unit. If an abnormality occurs in inband communication, the charging-control ECU opens the power supply relay, instructs the power-control computer to shift into sleep mode, and subsequently shifts itself into sleep mode. The power-control computer opens the SMR and the power supply switch, and subsequently shifts into sleep mode.
