  • Patent number: 10076966
    Abstract: This contactless power transmission device transmits power to a contactless power reception device having a reception-side coil and a reception-side resonator which resonates with the reception-side coil. The contactless power transmission device has a transmission unit including a transmission-side coil, a transmission-side resonator which resonates with the transmission-side coil, and an inverter for feeding power to the transmission-side resonator. The inductance value of the transmission-side coil and/or the capacitance value of the transmission-side resonator is set so that the frequency range in which the phase difference of a primary-side current flowing through the transmission unit relative to a primary-side voltage applied to the transmission unit is zero or above is wider than when the inductance value of the reception-side coil are equal to each other as are the capacitance value of the reception-side resonator and the capacitance value of the transmission-side resonator.

  • Patent number: 10071788
    Abstract: A speed control system for electric bicycles includes a bicycle having pedals, a motor and a battery which provides electric power to the motor. The bicycle includes a speed detector to detect speed of the bicycle to create a current speed value. A controller is electrically connected to the motor, the battery and the speed detector. The controller has a preset constant-speed setting value. The controller receives the current speed value from the speed detector, and compares the current speed value with the preset constant-speed setting value to adjust output of the motor and the battery. The controller changes the output of the motor and the battery according to the current speed so that the motor assists the rider to operate the bicycle instantly.

  • Patent number: 10065517
    Abstract: Methods and systems for autonomous vehicle recharging or refueling are disclosed. Autonomous electric vehicles may be automatically recharged by routing the vehicles to available charging stations when not in operation, according to methods described herein. A charge level of the battery of an autonomous electric vehicle may be monitored until it reaches a recharging threshold, at which point an on-board computer may generate a predicted use profile for the vehicle. Based upon the predicted use profile, a time and location for the vehicle to recharge may be determined. In some embodiments, the vehicle may be controlled to automatically travel to a charging station, recharge the battery, and return to its starting location in order to recharge when not in use.
