  • Patent number: 10682921
    Abstract: A system for charging one or more batteries of a vehicle may include a charging box mounted to a vehicle to facilitate connection to a charge coupler from under the vehicle. The charge coupler may be configured to provide an electrical connection between an electrical power source and the charging box. A vehicle including the charging box may maneuver to a position above the charge coupler, after which electrical contacts of the charging box and the charge coupler may be brought into contact with one another. The charge coupler and/or the charging box may be configured to provide electrical communication between the electrical power source and the one or more batteries, so that the electrical power source may charge one or more of the batteries. Thereafter, the electrical contacts may be separated from one another, and the vehicle may maneuver away from the charge coupler.

  • Patent number: 10640000
    Abstract: The invention relates to a method for detecting a direct-current fault current in an electrical alternating-current circuit, wherein a rectifier unit (14) is connected to an alternating-current network (34) by means of a primary side (13) and provides a direct current on a secondary side (15) and wherein the alternating-current network (34) is protected by means of a fault-current circuit breaker (38), which interrupts the circuit if an alternating-current fault current greater than a specified alternating-current tripping threshold occurs. A direct-current fault current on the primary side (13) is measured and is compared with a specified direct-current tripping threshold. An alternating-current fault current is produced if the direct-current fault current lies above the tripping threshold. The invention further relates to a device (10) for detecting a direct-current fault current and to a charging apparatus (12) comprising such a device (10).
