  • Patent number: 11901751
    Abstract: An indexed sequence of bits in a buffer is allocated for tracking a battery charging state. The indexed sequence of bits has a first number of bits. A battery voltage of a rechargeable battery is sampled at a sampling rate. For each sampled battery voltage, the battery voltage is compared with a voltage threshold. A next bit position in the indexed sequence of bits is identified. In accordance with a determination that a comparison result is true, a predefined first value is added to the next bit position. A second number of bits that are filled with the predefined first value is determined. A ratio between the second number and the first number is also determined. In accordance with a determination that the ratio exceeds a threshold step-down ratio, a battery charge voltage is stepped down. The rechargeable battery is charged to a step-down voltage.

  • Patent number: 11894696
    Abstract: In a method and an apparatus for detecting electrically conductive foreign bodies during inductive energy transmission between a primary coil (1) and a secondary coil (2), at least one sensor coil (5) is arranged between the primary coil (1) and the secondary coil (2), and a current flowing in the sensor coil (5) due to the induced voltage during the energy transmission is detected and evaluated. In this case, the sensor coil (5) is connected to at least one capacitor to form a resonant circuit which is matched to the excitation frequency of the primary coil (1). The phase position of the current in the resonant circuit in relation to a reference signal is then used to determine whether there are electrically conductive foreign bodies (4) between the primary coil (1) and the secondary coil (2). A high degree of sensitivity, also in relation to small electrically conductive foreign bodies within the energy transmission path, is achieved by means of the method and the apparatus.
