Abstract: A method for charging sequence control of a power electronics system, in which a charging power is provided by the power electronics system, in which a charging unit, which is operated by a user and which transfers the charging power to a battery, is controlled by a charging control system. A communication exchange is carried out at least between a control device of the power electronics system and the charging control system, in which a plurality of charging process states are predetermined, in which sequences between the charging process states are stored in a program sequence plan and in which the program sequence plan is used for charging sequence control of the power electronics system. For the event of a fault the charging process states “Not ready to charge” and “Fault in charging process” are predetermined.

Abstract: A method for controlling a vehicle-external charging device for charging a vehicle. The charging device has an AC current grid having a neutral conductor, a protective conductor and at least one phase conductor, a protection and monitoring apparatus, and a DC current charging terminal. The vehicle includes a high-voltage on-board power system and an electrical energy storage element connected to the on-board power system. The method includes electrically connecting the on-board power system to the DC current charging terminal of the charging device, and detecting a protective conductor resistance between the neutral conductor and the protective conductor by feeding in a test current by way of the protection and monitoring apparatus. A frequency of the test current is either outside of a compensation frequency range of the protection and monitoring apparatus or within the compensation frequency range and is filtered out of the compensation frequency range on a narrowband basis.

Abstract: An air inlet device for a cooling device of an electric vehicle, having an air inlet duct with a duct wall delimiting a duct volume and at least one duct opening for the admission of ambient air for guiding to the cooling device. An acoustic device for pedestrian protection is arranged in the duct wall in a flow-neutral manner with respect to the flow of ambient air, with a speaker device for generating a protective noise.

Abstract: A sensor-controlled key system for a motor vehicle for releasing an access authorization and for actuating auxiliary functions includes a control device having an electronic key device. The key system further includes at least one optical sensor device with at least one optical sensor element. The optical sensor element has a beam path that defines at least two observation regions B1, B2, Bn. The control device has a switching function that switches observation regions B1, B2, Bn on and off in dependence on a verified or non-verified access authorization.

Abstract: A closure device for closing an access opening in a motor-vehicle body. An inner chamber is accessible via the access opening and the access opening can be closed by a cap element. The cap element is connected to a guide device, which is arranged in the inner chamber and via which the cap element can be adjusted between a closed position and an open position. The guide device is configured such that the cap element executes a pushing movement and a lifting movement as it moves between the closed position and the open position. The cap element, in the open position, is arranged in the inner chamber.
