  • Patent number: 11519709
    Abstract: A position sensor is configured to use a Wiegand wire, position magnet(s) and a reset magnet in which changes in polarization of the Wiegand wire caused by the position magnet(s) can be reset by the reset magnet. The position magnet(s), which can move in relation to the Wiegand wire, can have relatively stronger magnetic flux densities, and the reset magnet, which can be fixed in relation to the Wiegand wire, can have a relatively weaker magnetic flux density. When the position magnet(s) are proximal the Wiegand wire, the relatively stronger position magnet(s) overcome the reset magnet to cause a change in polarization of the Wiegand wire which produces an electrical pulse which can be counted. However, when the position magnet(s) become distal to the Wiegand wire, the relatively weaker reset magnet can reset the polarization of the Wiegand wire to prepare for a next count.

  • Patent number: 11465525
    Abstract: The invention relates to means for a calibration standards-compliant determination of the electrical energy transferred from a charging station, which make a measurement at the transfer point, that is to say at the vehicle-side end of the charging cable, unnecessary. Here, the electrical energy transferred from a charging station is determined by a measurement of the energy before the transfer point, wherein the reactive power component from the termination point as far as the transfer point is compensated. The reactive power component is determined from at least one second electrical variable, for example a resistance of a conductor or a conductor shield, which is in a fixed relationship with an analog electrical variable that is relevant to the transferred electrical energy, for example an ohmic total resistance of at least two conductors involved in a charging circuit.
