ELECTRICAL POWER DISTRIBUTION SYSTEM FOR A MOTOR VEHICLE
The invention relates to an electrical power distribution system for a motor vehicle, comprising a first partial power distribution system providing a first power distribution system voltage and a first power storage unit and at least one electrical consumer, and a second partial power distribution system providing a second power distribution system voltage and a second power storage unit and at least one electrical consumer. Said two partial power distribution systems can be selectively coupled to each other by means of a controllable electrical coupling device. A generator driven by the vehicle provides electrical energy to the power distribution system via the first partial power distribution system and is sized so that the value of the first power distribution system voltage at the maximum generator excitation exceeds that of the second power distribution system voltage by a multiple. According to the invention, the first power storage unit is formed from at least two storage elements that can be selectively switched between a series and a parallel connection by means of a controllable switching device.

An electronic actuating device is disclosed for activating and/or for controlling the power consumption of an electric load in the form of a heating element. Said actuating device comprises an electric activation device, which is connected in series to the load and switches the electric load on/off, or controls the power consumption thereof, depending on actuating signals of a control electronics unit. According to the invention, the electric activation device is composed of two activation elements, which are connected in series to each other, and an over-current detection circuit is provided, which blocks one of the two switching elements if the current supplied to the load exceeds a predetermined amperage.
The invention relates to an electric heater comprising a fluid-conducting housing, in which at least one, preferably helical, heating unit, preferably a wire resistance heating element, is accommodated. The heating unit can have a tubular outer body, in which a heating element electrically contacted with a control circuit accommodated in an electronics housing is embedded. According to the invention, end sections of the heating unit extend in a sealed manner through the fluid-conducting housing to, and preferably into, an electronics housing. The invention further discloses a method for actuating an electric heater and to a heater that can be operated according to such a method, wherein said heater is designed with at least one resistance heating element, which acts as a temperature sensor, so that the temperature thereof can be used for actuating the heater.

The invention relates to a tank removal device (1), comprising a cold start heater (6) for frozen fluids (11) from a motor vehicle tank system having at least one primary tank (2), at least one heat emission element (13, 27, 33), which is connected to at least one heating element (19) in a heat-conducting manner and conducts the heat produced in the heating element (19) into the frozen fluid (11), whereby a cold start volume (5) is melted, and to a method for removing a frozen fluid (11) from the motor vehicle tank system. In order to be able to remove the fluid (11) of the cold start volume (5) from the motor vehicle tank system, without requiring an additional ventilation device (10) or a separate removal line (20, 20'), it is provided according to the invention that the cold start volume (5) extends from a gas volume (12) above the frozen fluid (11) to the removal opening (4). The invention further relates to a method, wherein the cold start volume (5) is melted by a fluid level (O) of the frozen fluid (11) adjoining a gas volume up to a removal opening (4) of the tank system.
