  • Patent number: 9490064
    Abstract: A wireless power transmission method transmits power from a first resonance antenna to a second resonance antenna in a noncontact manner through resonance of a magnetic field. The first resonance antenna is a resonance antenna of a power transmitting device, the second resonance antenna is a resonance antenna of a power receiving device. The wireless power transmission method includes setting a first transmission efficiency between the first resonance antenna and the second resonance antenna by changing a frequency of supply power of the power transmitting device. Power transmitted from the first resonance antenna to the second resonance antenna is gradually increased.

  • Patent number: 9472973
    Abstract: A non-contact charging apparatus includes a power-feeding coil, a power-receiving coil, a relative-position detector, and a feeding-power changing device. The power-receiving coil is configured to receive power from the power-feeding coil in a non-contact manner to charge a battery. The relative-position detector is configured to detect a distance between a center of the power-feeding coil and a center of the power-receiving coil. The feeding-power changing device is configured to decrease the power from the power-feeding coil to the power-receiving coil as the distance increases.

  • Patent number: 9428067
    Abstract: A vehicle running management system under renewable energy includes an electrically driven vehicle having a battery ECU. The battery ECU manages a remaining amount of renewable energy in a vehicle-mounted electric storage device as it increases and decreases when renewable energy is charged into the vehicle-mounted electric storage device and renewable energy is discharged from the vehicle-mounted electric storage device.

  • Patent number: 9233616
    Abstract: A vehicle-mounted electric storage device of an electrically driven vehicle is charged with a necessary amount of energy, which corresponds to an amount of energy consumption in a next-time running of the electrically driven vehicle, such that a shortage of renewable energy at a charging site is compensated for by charging the electrically driven vehicle with system energy.

  • Patent number: 9174548
    Abstract: An energy power depositing/charging management system and method is provided. When energy is deposited in an energy storage station from an onboard power storage device of a vehicle, a vehicle energy management unit manages reductions in the remaining stored energy level of energy in the onboard power storage device. The vehicle energy management unit and a storage station energy management unit manage increases in the energy remaining amount of deposited energy in the energy storage station, thereby allowing for charging up to the remaining amount of deposited energy of energy identified with an ID for the vehicle in the energy storage station.

  • Patent number: 8061294
    Abstract: To provide a temperature-sensitive indicator which, when using the temperature-sensitive indicator having a capsule packed with a heat-sensitive material, enables easy rupture of the capsule, without being affected by the temperature of a finger of a user. The indicator includes: a base; a concave portion formed in the base; a capsule accommodated in the concave portion and packed with a heat-sensitive material; an absorbing member placed on the capsule; pressing means which is arranged above the absorbing member, and which is formed of a transparent heat insulating material; and a cover which covers at least the capsule and the absorbing member. By pressing on the capsule using the pressing means 6, the capsule is ruptured.
