Problems solved by technology

At very low ambient temperatures, for example between -10°C and -35°C, the required heating power can be greater than the required driving power, that is to say, the driving range of the vehicle is thus greatly reduced
Additionally, defrosting windows becomes increasingly difficult as the ambient temperature decreases
If one further considers that battery capacity decreases at low temperatures, battery-powered electric vehicles are significantly less efficient at heating than vehicles with internal combustion engines

Embodiment Construction

[0032] In the different figures, the same components are always given the same reference numerals, so they are usually only described once.

[0033] figure 1 is a side sectional view of a motor vehicle 1 (in this example a passenger car). figure 2 is a rear view of the motor vehicle 1 and also serves as a sectional view. The motor vehicle 1 has an interior 2 in which a front seat 3 and a rear bench seat 4 are arranged. A dashboard 6 and a steering wheel 7 are arranged on the front console 5 . In the upward direction, the interior space 2 is delimited by the roof 8 , forwardly by the windshield 9 , laterally by the side windows 10 , and rearwardly by the rear window 11 .

[0034] In order to heat windshield 9 from the inside, for example for defrosting, a heating system 20 is provided. Integrated below the console 5 is a fan unit 21 which delivers hot air from a heat source 22 . In this case, the heat source 22 is only schematically shown. If the motor vehicle 1 is desig...

Abstract

A heating system (20) for a windshield (9) of a vehicle (1), in which a fan unit (12) is configured to produce a hot air flow (W) at the inner side of the windshield (6). In order to enable efficientheating of a windshield of an electric vehicle, there is provision for the heating system to have an at least predominantly transparent partition unit (24), which in a shielding position (A) is secured in the vehicle (1) in such a manner that it is arranged in the longitudinal vehicle direction between at least a predominant portion of the windshield (9) and an inner region which is provided for passengers, whereby the hot air flow (W) can be guided at least partially in a heating region (2.2) between the windshield (9) and the partition unit (24).

Description

technical field [0001] The invention relates to a heating system for a windshield of a vehicle, wherein a fan unit is configured to generate a hot air flow inside the windshield. Background technique [0002] In a battery powered electric vehicle (also called BEV, battery electric vehicle) it is not possible to use excess heat from the engine for heating purposes, which is possible with vehicles with an internal combustion engine. Therefore, a significant portion of the battery power must be used to heat the vehicle or defrost the windshield, side and rear windows. At very low ambient temperatures, for example between -10° C. and -35° C., the required heating power can be greater than the required driving power, ie the driving range of the vehicle is thus considerably reduced. Additionally, defrosting windows becomes increasingly difficult as ambient temperatures decrease. If it is further taken into account that battery capacity decreases at low temperatures, battery-powe...
