A solar system for a motor vehicle has a solar generator and an energy storage for supplying power to at least one power consuming device, the solar generator being intended for charging of the energy storage, which is formed by at least one high-capacitance capacitor.

Solar system for a motor vehicle

A solar cover for a motor vehicle roof, which is provided with an outside transparent cover plate ( ) and an inside cover ( ) between which at least one solar cell ( ) is embedded, an electrical contact ( ) from which the solar current from the at least one solar cell is directed to the motor vehicle, and an electrical connector element which produces electrical contact between the at least one solar cell and the contact is embedded between the cover plate and the cover. The contact ( ) is located in the horizontal direction outside of the area of the cover plate ( ) which is covered by the cover ( ) and the electrical connector ( ) extends in the horizontal direction beyond the area covered by the cover to the contact.

Solar cover for a motor vehicle roof and a process for its manufacture

A motor vehicle roof with a roof opening which can be closed or at least partially exposed by a displaceable closure element ( ) which has an electrical element ( ), an displaceable headliner part ( ) for concealing the closure element and at least one coupling element ( ) which acts as a driver to entrain the headliner part in the displacement motion of the closure element. The coupling element furthermore provides for electrical contact between the electrical element of the closure element and a contact element ( ) which is provided on the headliner part to establish electrical contact between the electrical element of the closure element and a vehicle-mounted electrical element.

Motor vehicle roof with adjustable closure element

A solar system for a motor vehicle, which is provided with a solar generator and a DC/DC converter unit, the solar system being switchable for supplying a power consuming device in the motor vehicle or for recharging of the motor vehicle battery. The DC/DC converter unit is made with two poles on the output side and functionally comprises a first and a second DC/DC converter which are respectively optimized with respect to the supply function of the power consuming device and the recharging function, there being a changeover unit which acquires the voltage at the output of the DC/DC converter unit and switches the output depending on the acquired voltage to either the first DC/DC converter or the second DC/DC converter.

A ventilation device for the seat ( ) of a motor vehicle ( ) which has an electrically driven fan ( ), the vehicle ( ) having a solar cell arrangement ( ) which, with the vehicle ( ) turned off, provides a supply of solar generated power for operation of the fan ( ).

Ventilation device for the seat of a motor vehicle

A motor vehicle roof with a solar generator which is securely attached on the outside on the solid roof skin for producing solar current for the vehicle. The solar generator can be adjusted between a first spatially compact configuration and a second, less spatially compact configuration in which its active solar surface projected onto the plane of the roof is larger than in the first configuration. The invention also relates to a motor vehicle roof with an attachment element which runs in the lengthwise direction of the roof and which is mounted externally on the solid roof skin and which is made such that a mobile flat solar generator can be pushed into the attachment element and is held in the working configuration by it to produce solar current.

Motor vehicle roof with outside solar generator

A solar module ( ) for mounting on motor vehicles, which is provided with a top cover layer ( ) and a bottom cover layer ( ), between which a solar generator ( ) is embedded which has a plurality of electrically interconnected solar cells ( ), and with two electrical connections ( ) on a connection side for tapping of the solar current generated by the solar generator. There are connections ( ) on a connection socket ( ) which is located on one side of the solar module ( ), and of which the side ( ) facing away from the connection side is embedded in a sealed manner between the two cover layers ( ).

Solar module for attachment to motor vehicles and a process for its manufacture

A motor vehicle roof with a closure element (,) for a roof opening (,) which can be displaced between a closed position and an open position and which is provided with a primary solar generator (,). The closure element (,) is made such that an additional element (,) which has an additional solar generator (,) can be coupled to the closure element in the open position of the closure element, such that the additional element assumes a working position on the outside of the vehicle to generate solar current.

Solar motor vehicle roof

A circuit for power supply of a ventilation fan for cooling the interior of a motor vehicle and/or a motor vehicle battery by means of solar cells, with a manually actuated switch for switching the solar cell power supply to the ventilation fan or battery. An automatic control provides a fully automatic mode for automatic switching of the solar cell power supply depending on the temperature in the motor vehicle interior and/or the battery charging state which can be overridden by activating an actuating element of a manually activated switch in a semiautomatic mode. Furthermore, there is an optical display for indicating which of the automatic and semiautomatic mode is activated.

An improved motor vehicle roof is provided which includes a roof opening provided in a fixed roof surface, at least one closing element for selectively at least partially closing the roof opening, an electrical adjusting drive for driving the closing element and a sensor engineering system for detecting a situation which adversely affects the safety of the passengers and for producing a corresponding danger signal. Importantly, the roof includes a quick-action closing device coupled to the sensor engineering system which causes the closing element to close from its open or partially open position when a danger signal is present. The closing device includes means for producing an electrical voltage which exceeds the normal feed voltage (rated voltage) of the adjusting drive by several times, and for applying the voltage to the electric adjusting drive.

Motor vehicle roof

An arrangement for supplying power to a motor vehicle electrical system (,) by means of a motor driven vehicle generator (,) and a solar generator (,). To efficiently save fuel, for power generation the arrangement compares the output or energy balance of the solar generator (,) relative to the vehicle generator (,) and reduces the vehicle generator output in proportion to the solar current supplied when a positive energy balance exist in favor of the vehicle generator (,) and separates the vehicle generator (,) from the vehicle engine (,) when a positive energy balance exists in favor of the solar generator (,).

Method and arrangement for supplying power to a motor vehicle electrical system

Solar roof for motor vehicles with a solar generator having solar cells for supplying power to a power consumer and/or a battery and with a D.C. converter for impedance matching between the solar generator and the consumer and/or battery. The D.C. converter is a flat module and is integrated into the solar cell carrying roof panel.

Solar roof for motor vehicles

Circuit arrangement for supplying power to a fan and/or battery from solar energy generator in a motor vehicle. A DC voltage converter using impedance matching between the solar energy generator and the fan or the battery includes a switch that is alternately opened and closed by a pulse-width-modulated operating signal, and is part of the circuit arrangement. To generate the operating signal, a microprocessor, a frequency generator and a pulse width modulator, which is acted on by the output signal of the frequency generator and a control signal of the microprocessor, are provided. These components also are used as components of an actuating device to displace a movable part of a sun roof, a changeover signal switching between use for charging a battery and/or powering a fan and use operating the sun roof. Thus, the circuit arrangement is able to fulfill multiple functions.
