  • Publication number: 20140042983
    Abstract: In a vehicle including a charge circuit for carrying out external charging to charge a vehicle-mounted battery with a power supply external to the vehicle, a vehicle ECU. determines that there is an impedance error when a state where a reduction width of an input voltage Vin applied to the charge circuit from the power supply external to the vehicle is exceeding a threshold width ?V continues for a predetermined time, and outputs a first termination instruction to a charger ECU. The charger ECU receiving the first termination instruction causes the charge circuit to stop to terminate external charging. The charger ECU controls the charge circuit such that, when the input voltage Vin falls down to a threshold voltage V1 the current flowing through an external power supply system is reduced to suppress further reduction in the input voltage Vin.

  • Patent number: 7175698
    Abstract: In a canister, an activated charcoal layer is placed in a fluid passage by which an air intake port is connected to a charge port or purge port, and a chamber dividing the charcoal layer into sections so as to traverse the fuel passage is defined by a grid and a filter pad placed on the surface of the grid. The grid has apertures uniformly formed on the surface of the grid contacting with the filter pad, so as to communicate with the chamber. Formation of the apertures on the surface of the grid prevents the filter pad from coming into the mesh of the grid, thus maintaining flatness of the filter pad.
