Abstract
Description
Die Erfindung betrifft einen Energiespeicher gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an energy store according to the preamble of the claim 1.
Bekannte Fahrzeugbatterien, z. B. NiMH-Batterien oder LiIonen-Batterien bestehen aus mehreren in Reihe geschalteten Einzelzellen, die jeweils eine Teilspannung von wenigen Volt, z. B. 2 V, erzeugen. Die Anzahl der Zellen bestimmt dabei die Nennspannung der Batterie, die z. B. 12 V oder 42 V, bei Hybrid-Fahrzeugen auch 500 V betragen kann.Known Vehicle batteries, z. B. NiMH batteries or LiIonen batteries exist consisting of several series-connected single cells, each one Partial voltage of a few volts, z. B. 2 V generate. The number of Cells determines the rated voltage of the battery, the z. B. 12 V or 42 V, for hybrid vehicles can also be 500V.
NiMH- und LiIonen-Batterien arbeiten typischerweise nur bei Temperaturen von mehr als –20°C. Unterhalb dieser Temperatur ist der Innenwiderstand der Batterie so groß, dass kein oder nur ein schwacher Batteriestrom möglich ist.NiMH and Li ion batteries typically only operate at temperatures of more than -20 ° C. Below At this temperature, the internal resistance of the battery is so great that no or only a weak battery power is possible.
Um den Einsatzbereich der Batterien auf Temperaturen von bis zu –55°C zu erweitern, werden bekannte Batterien von außen durch eine externe Wärmequelle geheizt. Aufgrund des relativ hohen Wärmewiderstandes der Batterie dauert das Aufheizen jedoch sehr lange, in der Regel etwa 10 min bis 20 min. Diese Zeitdauer ist im Falle von Fahrzeugen nicht akzeptabel.Around extend the range of application of the batteries to temperatures of up to -55 ° C, Be known batteries from the outside by an external heat source heated. Due to the relatively high thermal resistance of the battery However, the heating takes a long time, usually about 10 min up to 20 min. This period of time is unacceptable in the case of vehicles.
Das Problem der mangelnden Verfügbarkeit bei niedrigen Temperaturen besteht auch bei anderen Energiespeichern, wie z. B. Kondensatoren.The Problem of lack of availability Low temperatures also exist with other energy storage systems, such as B. capacitors.
Es ist somit die Aufgabe der vorliegenden Erfindung, einen Energiespeicher mit einer Heizvorrichtung zu schaffen, der wesentlich schneller aufgeheizt werden kann. Darüber hinaus soll ein Verfahren zum Aufheizen eines Energiespeichers entwickelt werden, das wesentlich schneller und effektiver ist.It is thus the object of the present invention, an energy storage with a heater to create that much faster can be heated. About that In addition, a method for heating an energy store is being developed which is much faster and more effective.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1, sowie im Anspruch 6 angegebenen Merkmale. Weitere Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Is solved this task according to the invention by the features specified in claim 1, as well as in claim 6. Further embodiments of the invention are the subject of dependent claims.
Bezüglich des konstruktiven Aufbaus des Energiespeichers besteht ein wesentlicher Aspekt der Erfindung darin, den Energiespeicher bzw. wenigstens eine Zelle des Energiespeichers mit einem Heizelement zu versehen, das direkt auf einem Pol angeordnet ist. Wenn die Heizelemente so ausgelegt sind, dass zwischen Pol und Heizelement ein großflächiger thermischer Kontakt besteht, kann der Energiespeicher sehr schnell aufgeheizt werden.Regarding the constructive structure of the energy storage is an essential Aspect of the invention therein, the energy storage or at least to provide a cell of the energy store with a heating element, which is arranged directly on a pole. If the heating elements like that are designed that between pole and heating element, a large-scale thermal Contact, the energy storage can be heated up very quickly become.
Die einzelnen Heizelemente sind gegenüber ihrem jeweiligen Pol vorzugsweise elektrisch isoliert. Hierzu ist vorzugsweise eine sehr dünne, thermisch gut leitfähige Isolationsschicht zwischen Heizelement und Pol vorgesehen.The individual heating elements are preferably opposite to their respective pole electrically isolated. For this purpose, preferably a very thin, thermally good conductive Insulating layer between heating element and pole provided.
Bei den Heizelementen handelt es sich vorzugsweise um großflächige Elemente, die wenigstens 50% der Fläche des Pols bedecken.at the heating elements are preferably large-area elements, the at least 50% of the area of the pole.
Um einen (beliebigen) Energiespeicher mit Heizvorrichtung möglichst effektiv aufzuheizen wird folgendes Verfahren vorgeschlagen: Gemäß der Erfindung wird die Heizvorrichtung bei sehr niedrigen Temperaturen zunächst von einer externen Energiequelle mit elektrischer Leistung versorgt. Der Energiespeicher wird dadurch geringfügig erwärmt. Sobald der Energiespeicher genügend Leistung bereitstellen kann, um sich selbst weiter aufzuheizen, wird die Energieversorgung von der externen Quelle auf den Energiespeicher umgeschaltet. Dadurch findet eine Selbsterwärmung statt, bei der sich der Energiespeicher aufgrund seines ohmschen Innenwiderstandes (Verlustleistung) selbst aufheizt. Gleichzeitig wird der Energiespeicher noch durch die Heizvorrichtung aufgeheizt. Der Aufheizvorgang vollzieht sich daher sehr rasch.Around a (arbitrary) energy storage with heater as possible To effectively heat the following method is proposed: According to the invention The heater is initially used at very low temperatures powered by an external power source with electrical power. The energy storage is thereby heated slightly. Once the energy store enough Can provide power to further fuel itself, the energy supply from the external source to the energy storage switched. As a result, a self-heating takes place, in which the Energy storage due to its ohmic internal resistance (power dissipation) itself heats up. At the same time the energy storage is still through heated the heater. The heating process takes place therefore very fast.
Zum Umschalten der Versorgung zwischen der externen Energiequelle und dem Energiespeicher ist vorzugsweise eine entsprechende externe Beschaltung mit einer Schalteinrichtung vorgesehen.To the Switching the supply between the external power source and the energy store is preferably a corresponding external circuit provided with a switching device.
Der Prozess der Selbsterwärmung wird vorzugsweise durch eine Heiz- und Entladesteuerung oder -Regelung kontrolliert.Of the Process of self-heating is preferably by a heating and discharging control or regulation controlled.
Die Erfindung wird nachstehend anhand der beigefügten Zeichnungen beispielhaft näher erläutert. Es zeigen:The Invention will be exemplified below with reference to the accompanying drawings explained in more detail. It demonstrate:
