  • Voltage and polarity negotiation based mobile device battery charging
    Patent number: 10153648
    Abstract: A method and apparatus for implementing a charging process is provided. The method includes determining that a charging surface of a mobile device is currently located on a charging surface of a structure including a charging apparatus. The charging surface of the mobile device includes charge receiving contacts electrically connected to a battery and a processor. The charging surface of the structure includes charging contacts electrically connected to a charging circuit and in communication with a controller. The processor determines that at least two contacts of the charge receiving contacts are in electro/mechanical contact with at least two contacts of the charging contacts and in response, a negotiation process with the controller with respect to selecting at least one associated charging voltage and polarity for charging the battery is executed resulting in a charging process between the charging circuit and the battery being enabled.
    Type: Grant
