Problems solved by technology

[0005] However, due to the generally high number of low-voltage consumers in electric vehicles, the converter must have a correspondingly high converter power, which leads to a higher dead weight (Eigenmasse) and higher converter losses

Embodiment Construction

[0041] figure 1 A system 10 according to the invention is shown with an inventive protective window 12 for a vehicle 14 . Currently, the protective glass 12 is a windshield 16 for a motor vehicle 18 . vehicle 14 or motor vehicle 18 in figure 2 In detail.

[0042] back to figure 1 , the system 10 shown comprises a voltage source 20 capable of providing a supply voltage U typical for the vehicle 14 in the high voltage range B . Supply voltage U B Currently 380 volts to 400 volts. Such a supply voltage U B Particularly suitable for electric vehicles 22, as in the figure 2 as detailed in.

[0043] Also in figure 1As shown in , the cover glass 12 includes a first conductive layer 24 and a second conductive layer 26 . The first and second conductive layers 24 , 26 are disposed between the first glass layer 28 and the second glass layer 30 . Furthermore, a plastic layer 32 is arranged between the first and second conductive layers 24 , 26 . It should be understood that...

Abstract

The invention relates to an electrically heatable windscreen for a vehicle (14), which is typically operated at an operating voltage from 380 volts to 400 volts. The windshield has the following structure to allow connection of the windshield directly to said operating voltage, to implement such a heating function: integrated between two glass panes is a plastic pane in the material of which electrically conductive particles (36) are distributed and which thus grant the plastic layer (32) a defined specific electrical resistance. An electrical contact layer is provided between each glass pane and the plastic layer (32) to enable a current flow (I) to implement the heating function via the plastic layer (32),.

Description

technical field [0001] The invention relates to a protective window for a vehicle according to the preamble of claim 1 , a system according to the preamble of claim 7 and a motor vehicle according to the preamble of claim 9 . Background technique [0002] In the field of vehicles, such as motor vehicles, protective glazing, such as windshields, assumes the most diverse functions. Protection against external mechanical effects and radiation (eg infrared radiation) are among the main functions of windshields. [0003] Furthermore, it is known that windshields can be made heated, so that their anti-fog and anti-icing properties can always be guaranteed. [0004] Such heatable protective glasses are conventionally operated at a low voltage range of 14 volts to 48 volts. Due to the increased electrification in motor vehicles, which are generally operated in the high voltage range of more than 48 volts, in particular in the range of 380 to 400 volts, corresponding voltage conve...
