  • Publication number: 20190131803
    Abstract: A wireless charger output protection system and method is provided for protecting a battery in an electric vehicle during wireless charging from both a desired power source and a stray power source. A wireless power transfer system includes a wireless charger on the electric vehicle side that receives power wirelessly from a charging base. The wireless charger output protection system and method shuts down the wireless charger output and dumps energy in a receive antenna (e.g., a vehicle pad) when a low-voltage battery connected to the wireless charger is lost. The wireless charger output protection system and method also shuts down the wireless charger output and dumps unwanted energy in the receive antenna (e.g., a vehicle pad) when power is transferred from a stray power source coupled to the receive antenna.

    Abstract: A wireless charger output protection system and method is provided for protecting a battery in an electric vehicle during wireless charging. A wireless power transfer system includes a wireless charger on the electric vehicle side that receives power wirelessly from a charging base. The wireless charger output protection system and method shuts down the wireless charger output and dumps energy in a receive antenna (e.g., a vehicle pad) when a charging error is detected before the charging base can be shut down. The system and method employs a zero-voltage switching (ZVS) scheme to shut down the wireless charger output, in response to the charging error, to protect the switching devices and enhance overall reliability.

  • Patent number: 10011193
    Abstract: Seats and methods for controlling a seat are described. A position of the user's leg is sensed relative to the position of the front of the seat. A determination is made as to if the position of the user's leg from a front of the seat is greater than a gap minimum. If the gap is greater than the gap minimum, a cushion length extender portion of the seat is moved until the sensed position is less than or equal to the gap minimum. In an example, the remainder of seat base is held in a fixed position within the vehicle environment. The gap minimum can be with the cushion length extender portion in slight contact with the user's leg. The sensor can be at a front face of seat. The sensor can be on the cushion length extender portion of the seat.
