Abstract

The system has an auxiliary electrical heater heating air in an inner chamber before and after starting of a motor vehicle in a coolant circuit of a vehicle-internal combustion engine and a fuel cell. The coolant circuit is heated by the auxiliary electrical heater by using an energy storage i.e. lithium-ion-battery, of electric drives of the vehicle. Quantity of the coolant in the coolant circuit and engine parameters are provided under consideration of parameters such as external temperature, charging condition of a hybrid-battery and an intermediate level in a degree of coolant heating.

Description

Konventionelle Standheizungen, die mit dem Flüssigbrennstoff des Fahrzeugs betrieben werden, sind für die unteren Fahrzeugklassen oftmals nicht serienmäßig bestellbar oder aber im Vergleich zum Fahrzeugpreis überproportional teuer. Um die Vorzüge einer Standheizung auch für die vorgenannten Fahrzeuge finanziell attraktiv zu machen, bietet sich mit der Einführung von Hybridfahrzeugen und den damit im Fahrzeug verbauten leistungsstarken Akkus (Betriebsspannung 120 Volt und darüber) eine, wenn auch leistungsmäßig eingeschränkte, Alternative zu den nachfolgenden Hauptvorteilen einer konventionell betriebenen Standheizung an.conventional Parking heaters with the liquid fuel of the vehicle are for the lower vehicle classes often not available as standard or disproportionately expensive compared to the vehicle price. To the Benefits a heater also for offers the aforementioned vehicles financially attractive offers with the introduction of hybrid vehicles and thus built in the vehicle powerful Batteries (operating voltage 120 volts and above), albeit limited in terms of performance, alternative to the following main advantages of a conventionally operated Parking heater on.

Eine Standheizung ist im Kühlmittelkreislauf des Motors eingebaut und gibt ihre Wärme zum einen an den Motor zur Vermeidung von Kaltstarts und zum anderen an die Wärmetauscher der Lüftung zur Innenraumerwärmung ab. Bei entsprechendendem Zeitvorlauf besitzt der Motor je nach äußeren Umständen beinahe Betriebstemperatur, der Innenraum ist aufgeheizt und die Scheiben sind im Winter weitgehend eisfrei. Der vorgewärmte Motor emittiert beim Start weniger Schadstoffe. Weiterhin ist im Sommer eine Lüftungsfunktion aktivierbar.A Parking heater is in the coolant circuit of the Motors installed and gives their heat on the one hand to the engine to avoid cold starts and on the other to the heat exchangers the ventilation for interior heating from. If the lead time is sufficient, the engine will be almost depending on external circumstances Operating temperature, the interior is heated and the windows are largely ice-free in winter. The preheated engine emits at startup less pollutants. Furthermore, in the summer is a ventilation function enableable.

Bei einer mit Flüssigbrennstoff betriebener Standheizung ist die konstante Leistungsabgabe nur reglementiert durch eine unter einen Schwellenwert abfallende Fahrzeugbatteriespannung oder eine unter ein definiertes Minimum abfallende Tankfüllung. Mit den bisherigen 12-Volt-Fahrzeugbatterien war eine elektrische Alternative mangels Leistungsfähigkeit nicht realisierbar. Erst durch die Nutzung der leistungsstarken Hybrid-Akkus wird eine elektrische Kühlwasservorwärmung möglich, allerdings ist der Energievorrat nicht unbegrenzt.at one with liquid fuel operated auxiliary heating, the constant power output is only regulated by a vehicle battery voltage dropping below a threshold or a tank below a defined minimum tank filling. With the previous 12 volt vehicle batteries was an electrical alternative for lack of efficiency not feasible. Only through the use of powerful Hybrid batteries will An electric cooling water pre-heating possible, however the energy supply is not unlimited.

Die Akkukapazität sollte daher nur so schonend wie möglich eingesetzt werden, so ist nach meiner Ansicht eine Erwärmung des Kühlwassers auf 5–30 Grad Celsius im Winter für einen verschleißschonenden Motorstart ausreichend. Speziell bei den immer öfters aufgeladenen Motoren mit den hohen Leistungen aus kleinem Hubraum wirkt sich dies materialschonend aus. Entscheidend für die Erwärmung des Kühlwassers ist zum einen der Akkuladezustand, die Motorengröße und die Außentemperatur, welche die spätere Temperaturdifferenz zum erwärmten Kühlwasser beeinflusst. Aus letzteren Gründen ergibt sich die Notwendigkeit, dass das Heizsystem in die Fahrzeugelektronik integriert werden muss, da ebenso eine Schutzabschaltung des Systems bei Unterschreitung eines Schwellenwertes zum Schutz des Akkus vor Tiefentladung notwendig ist. Die Kühlwasserumwälzung, Innenraumbelüftung etc. kann zur Systemvereinfachung nach wie vor mit dem Bordstromnetz analog einer Standheizung erfolgen.The battery capacity should therefore be used only as gently as possible, so is a warming in my opinion of cooling water at 5-30 Degrees Celsius in the winter for a wear-resistant Engine start sufficient. Especially with the more often charged engines With the high performance from small cubic capacity, this material-friendly effect out. Decisive for the warming of the cooling water is on the one hand the battery charge state, the engine size and the outside temperature, which the later Temperature difference to the heated cooling water affected. For the latter reasons There is a need for the heating system in the vehicle electronics must be integrated, as well as a protective shutdown of the system when it falls below a threshold value to protect the battery Deep discharge is necessary. The cooling water circulation, interior ventilation etc. can continue to simplify the system with the on-board power supply system done analogous to a heater.

Die Möglichkeit zur Vorwahl einer Einschaltzeit sowie die zur System-Fernaktivierung mittels Funk, Telefon, etc. sollte neben dem manuellen Einschalten im Fahrzeug ebenfalls gegeben sein.The possibility for pre-selection of a switch-on time as well as for system remote activation by radio, telephone, etc. should be in addition to the manual power also be given in the vehicle.

Die technische Neuerung an diesem System ist die Nutzung des Energiespeichers vom Hybridantrieb zur ausschließlichen elektrischen Kühlwasservorwärmung in der Form, dass auch Zwischenstufen im Grad der Erwärmung des Kühlwassers (abhängig von den oben erwähnten Faktoren) zugelassen werden. Durch die ausschließliche elektrische Aufheizung ist die Nutzung auch in geschlossenen Garagen kein Problem. Durch die Möglichkeit mittels einer Umwälzpumpe die Wärmetauscher für die Lüftung mit vorgewärmtem Kühlwasser zu versorgen und somit eine (eingeschränkte) Innenraum-Temperaturerhöhung wie mit einer Standheizung zu bewirken, erleichtert zumindest das Eiskratzen und vermindert bei Fahrtantritt ein Beschlagen der Fahrzeugscheiben. Somit bietet diese Neuerung zumindest in den unteren Fahrzeugklassen eine kompakt bauende und kostengünstige technische Lösung zur Komfortsteigerung beim Fahrtbeginn im Winter.The technical innovation of this system is the use of energy storage from the hybrid drive to the exclusive electric cooling water heating in the form that also intermediates in the degree of warming of the cooling water (depending on the above mentioned Factors). Due to the exclusive electric heating is the use in closed garages no problem. By the possibility by means of a circulation pump the heat exchangers for the Ventilation with preheated cooling water to supply and thus a (limited) indoor temperature increase such to effect with a heater, at least facilitates the Eiskratzen and reduced when driving a fogging of the vehicle windows. Thus, this innovation offers at least in the lower vehicle classes a compact and cost-effective technical solution to increase comfort when driving in winter.
