Description
Die Erfindung betrifft ein Kraftfahrzeug mit einem Elektroantrieb. The invention relates to a motor vehicle with an electric drive.
Eine Aufgabe der Erfindung ist es, ein Kraftfahrzeug mit einem Elektroantrieb zu optimieren. Die Aufgabe wird durch den Gegenstand des unabhängigen Patentanspruchs gelöst. Einige besonders vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen und der Beschreibung angegeben. Ausgestaltungen der Erfindung können als Alternativen zu vorhandenen Lösungen eine überraschend effiziente Batterieisolation ermöglichen. An object of the invention is to optimize a motor vehicle with an electric drive. The object is solved by the subject matter of the independent patent claim. Some particularly advantageous embodiments of the invention are specified in the subclaims and the description. Embodiments of the invention may provide surprisingly efficient battery isolation as alternatives to existing solutions.
Zu einigen Ausgestaltungen der Erfindung gemäß den Unteransprüchen:
Nach Ausgestaltungen der Erfindung kann zur thermischen Isolation der Kraftfahrzeugs-Antriebs-Batterie diese mit Wärmedämmungselementen und/oder Montageelementen am Kraftfahrzeug montiert sein. Nach Ausgestaltungen der Erfindung kann durch einen öffenbaren Lüftungsmechanismus, insbesondere mit einer oder mehreren Lüftungsklappen und/oder Lüftungsventilen, die Kraftfahrzeugs-Antriebs-Batterie nach innen und/oder außerhalb des Kraftfahrzeugs belüftbar sein, insbesondere für eine Temperaturregelung der Kraftfahrzeugs-Antriebs-Batterie. To some embodiments of the invention according to the subclaims:
According to embodiments of the invention may be mounted with thermal insulation elements and / or mounting elements on the motor vehicle for thermal insulation of the motor vehicle drive battery. According to embodiments of the invention can be ventilated by an openable ventilation mechanism, in particular with one or more ventilation flaps and / or ventilation valves, the motor vehicle drive battery to the inside and / or outside of the motor vehicle, in particular for a temperature control of the motor vehicle drive battery.
Weitere Merkmale und Vorteile einiger vorteilhafter Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung von einigen Ausführungsbeispielen der Erfindung anhand der Zeichnung. Further features and advantages of some advantageous embodiments of the invention will become apparent from the following description of some embodiments of the invention with reference to the drawing.
Dabei zeigt zur Veranschaulichung von einigen möglichen Ausgestaltungen der Erfindung, vereinfachend schematisch: It shows to illustrate some possible embodiments of the invention, simplifying schematically:
Kraftfahrzeugs-Antriebs-Batterien Bat wie in
Deshalb soll eine Kraftfahrzeugs-Antriebs-Batterien Bat in einem kleinen Arbeitstemperaturfenster gehalten werden. Dies liegt, je nach Kraftfahrzeugs-Antriebs-Batterietyp abweichend, z.B. zwischen 10° und 30°C. Um eine Kraftfahrzeugs-Antriebs-Batterie Bat in diesem Temperaturbereich zu halten wird sie, von der genauen Applikation abhängig, gekühlt oder beheizt oder beides. Dafür wird Energie benötigt, die z.B. während des Ladens aus einer Ladesäule kommt oder ohne Ladesäule aus der Kraftfahrzeugs-Antriebs-Batterie selber. Die Heiz- und Kühlenergie für die Kraftfahrzeugs-Antriebs-Batterie Bat soll also so klein wie möglich gehalten werden, da sie Reichweiten-relevant sein kann. Deshalb werden Kraftfahrzeugs-Antriebs-Batterien Bat thermisch isoliert. Z.B. kann dies durch Einbringen von Isolationsmaterialien und/oder Schaummaterialien oder Wandaufbauten in Sandwichbauweise (z.B. Alu, Schaum, Alu) erfolgen. Therefore, a motor vehicle drive batteries Bat should be kept in a small working temperature window. This is different depending on the automotive drive battery type, e.g. between 10 ° and 30 ° C. In order to keep a motor vehicle drive battery Bat in this temperature range, it is dependent on the exact application, cooled or heated, or both. This requires energy, e.g. comes during charging from a charging station or without charging station from the motor vehicle drive battery itself. The heating and cooling energy for the motor vehicle drive battery Bat should therefore be kept as small as possible, since they can be range-relevant. Therefore, motor vehicle drive batteries Bat are thermally insulated. For example, This may be done by incorporating insulation materials and / or foam materials or wall structures in sandwich construction (e.g., aluminum, foam, aluminum).
Nach Ausgestaltungen der Erfindung kann überraschend effizient Luft Lft als Isolator verwendet werden. Die Einbauposition einer Kraftfahrzeugs-Antriebs-Batterie kann nach Ausgestaltungen der Erfindung in einem Kraftfahrzeug Kfz so angepasst sein, dass z.B. um die gesamte Kraftfahrzeugs-Antriebs-Batterie Bat herum ein geschlossenes, nicht vom Fahrtwind umströmtes Luftvolumen Lft entsteht. According to embodiments of the invention, surprisingly efficient air Lft can be used as an insulator. The installation position of a motor vehicle drive battery can be adapted according to embodiments of the invention in a motor vehicle motor vehicle such that e.g. around the entire motor vehicle drive battery Bat around a closed, not circulated by the wind air volume Lft arises.
Wenn um die Kraftfahrzeugs-Antriebs-Batterie Bat eine Schicht aus stehender Luft Lft erzeugt wird, in der es vorzugsweise auch keine oder keine großen Verwirbelungen gibt, kann die Luft Lft als Isolator wirken. Nach Ausgestaltungen der Erfindung soll auch die Wärmeleitfähigkeit der Kraftfahrzeugs-Antriebs-Batterie Bat selbst zur Umgebung minimiert werden, um die Wärmeleitung zu minimieren, z.B. durch isolierende Wärmedämmungselemente. If a layer of stagnant air Lft is generated around the motor vehicle drive battery Bat, in which preferably there are no or no large turbulences, the air Lft can act as an insulator. According to embodiments of the invention, the thermal conductivity of the motor vehicle drive battery Bat itself should also be minimized to the environment in order to minimize the heat conduction, e.g. by insulating thermal insulation elements.
Zusätzlich kann durch gezielte Belüftung zur Temperaturregelung der Kraftfahrzeugs-Antriebs-Batterie Bat beigetragen werden. Durch Luftklappen VentIn, VentOut zur Umgebung (AirIn, AirOut) kann man die Kraftfahrzeugs-Antriebs-Batterie Bat mit Außenluft umströmen lassen und so kühlen. Durch Luftklappen VentOut zum Innenraum des Kraftfahrzeugs Kfz kann man eine Abführung der Luft um die Kraftfahrzeugs-Antriebs-Batterie Bat in den Innenraum des Kraftfahrzeugs Kfz durchführen. Beide Belüftungsmaßnahmen können nach Ausgestaltungen der Erfindung so gesteuert oder geregelt sein, dass sie die zur Kraftfahrzeugs-Antriebs-Batterietemperierung notwendige Energie minimieren. In addition, can be contributed by targeted ventilation for temperature control of the motor vehicle drive battery Bat. By vent valves VentIn, VentOut to the environment (AirIn, AirOut) can be the motor vehicle battery drive Bat flow with outside air and cool it. By means of dampers VentOut to the interior of the motor vehicle Kfz can carry out a discharge of air to the motor vehicle drive battery Bat in the interior of the motor vehicle Kfz. Both venting measures can be controlled or regulated according to embodiments of the invention so that they minimize the energy required for motor vehicle drive battery temperature control.
