Abstract: A wireless-charging adapter is connectable to a direct current (DC) fast charger and includes an induction coil for wireless charging a second induction coil on a vehicle. In some instances, the adapter may include an electrical connector to mate with a DC fast charger. In addition, the adapter may include hardware and/or software to receive a DC from the DC fast charger and provide an alternating current (AC) to the induction coil. The induction coil of the adapter may be positioned (e.g., on a ground surface) to align with an induction coil on a vehicle.

Abstract: Methods and electric circuit arrangements for protecting metallic components in an electrolytic medium from corrosion due to direct-current (DC) stray current (Is) from a power supply system. The DC stray current may be jointly registered as a total sum current across all active conductors together with the protective conductor of the power supply system by a DC total differential-current sensor. Alternatively, a combined DC differential-current sensor is switchable by a switching device, a differential current being registered across all active conductors or the DC stray current being registered as a total differential current across all active conductors and the protective conductor. Alternatively, a differential current may be registered across all active conductors by a DC current sensor at the protective conductor and the DC stray current computed by forming differences of the differential current registered by the differential-current transformer and of the protective conductor registered by the DC current sensor.

Abstract: An example operation includes one or more of initiating, by a transport, a request to provide a first portion of stored energy to a charging station, determining, by the charging station, an actual amount of energy needed by the transport, wherein the determining is based on a first destination of the transport and on data received by the charging station based on a route associated with the first destination, wherein the actual amount of energy is not the same amount as the first portion of stored energy, and depositing, by the transport, the actual amount of energy in the charging station.

Abstract: A direct current fast charge (DCFC) system and associated method that lower standby power dramatically when the DCFC system is not in operation, and that provide a reset capability for communication needs. The DCFC system utilizes an appropriate load disconnection switch and an associated control and communication circuit, timer circuit, and automatic turn on system. This improves the reliability of the electronics by removing voltage stress during the standby mode. The DCFC system prevents energy waste, and therefore provides a “green” alternative to conventional DCFC systems.
