In modernen Fahrzeugen werden üblicherweise leistungsfähige Akkumulatoren zum Versorgen der elektrischen Fahrzeugverbraucher mit elektrischer Energie verwendet. Bei elektromotorisch betriebenen Kraftfahrzeugen, insbesondere in Hybrid- oder Elektrofahrzeugen, wird der Akkumulator häufig stationär über eine elektrische Steckdose geladen. Hier ist es besonders wichtig, technische Randbedingungen wie beispielsweise eine kurze Ladezeit und einen sicheren und unterbrechungsfreien Ladebetrieb einzuhalten.In modern vehicles, powerful accumulators are usually used to supply electrical vehicle consumers with electrical energy. In electric motor-powered motor vehicles, especially in hybrid or electric vehicles, the accumulator is often loaded stationary via an electrical outlet. Here it is particularly important to comply with technical constraints such as a short charging time and a safe and uninterrupted charging operation.

Die Aufgabe wird gelöst durch die Merkmale der unabhängigen Ansprüche. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The object is solved by the features of the independent claims. Advantageous embodiments of the invention are characterized in the subclaims.
Gemäß einem ersten Aspekt zeichnet sich die Erfindung aus durch eine Sicherungsvorrichtung, mit einer Stromerfassungseinheit, die ausgebildet ist zum Erfassen eines Stroms durch eine elektrische Sicherung, einer Ermittlungseinheit, die dazu ausgebildet ist abhängig von dem erfassten Strom durch die elektrische Sicherung einen Wert zu ermitteln, der repräsentativ ist für einen aktuellen Zusatzstromwert um den der Strom durch die elektrische Sicherung maximal erhöht werden kann ohne ein Auslösen der elektrischen Sicherung zu bewirken, und einer Kommunikationsschnittstelle, die dazu ausgebildet ist, den Wert, der repräsentativ ist für den aktuellen Zusatzstromwert, bereitzustellen zur Übertragung an eine Ladevorrichtung.According to a first aspect, the invention is characterized by a safety device having a current detection unit which is designed to detect a current through an electrical fuse, a detection unit which is designed to determine a value depending on the detected current through the electrical fuse, which is representative of a current boost current value by which the current through the electrical fuse can be maximally increased without causing the electrical fuse to trip, and a communication interface configured to provide the value representative of the current boost current value Transfer to a loading device.
Eine derartige Sicherungsvorrichtung hat den Vorteil, dass Informationen darüber zur Verfügung stehen können, mittels denen eine Überlastung der elektrischen Sicherung vermieden werden kann. Insbesondere kann ein Auslösen der elektrischen Sicherung vermieden werden. Damit können Unterbrechungen der Stromversorgung aufgrund von Überlastungen der elektrischen Sicherung vermieden werden.Such a security device has the advantage that information about it can be available by means of which an overload of the electrical fuse can be avoided. In particular, a triggering of the electrical fuse can be avoided. This can be avoided interruptions in the power supply due to overloading the electrical fuse.
Vorzugsweise ist der Wert, der repräsentativ ist für einen aktuellen Zusatzstromwert, um den der Strom durch die elektrische Sicherung maximal erhöht werden kann, ohne ein Auslösen der elektrischen Sicherung zu bewirken, abhängig von einem Wert, der repräsentativ ist für den maximal zulässigen Dauerstrom durch die elektrische Sicherung.Preferably, the value representative of a current boost current value by which the current through the electrical fuse can be maximally increased without causing the electrical fuse to trip is dependent on a value representative of the maximum allowable persistent current through the fuse electrical fuse.
Gemäß einem zweiten Aspekt zeichnet sich die Erfindung aus durch eine Ladevorrichtung, mit einer Kommunikationsschnittstelle, die ausgebildet ist zum Empfangen eines Werts, der repräsentativ ist für einen aktuellen Zusatzstromwert um den der Strom durch eine elektrische Sicherung maximal erhöht werden kann ohne ein Auslösen der elektrischen Sicherung zu bewirken, und einer Verarbeitungseinheit, die ausgebildet ist zum Anpassen eines Stroms für eine elektrische Verbrauchereinheit abhängig von dem Wert, der repräsentativ ist für den aktuellen Zusatzstromwert. Eine derartige Ladevorrichtung ermöglicht, den Strom für die elektrische Verbrauchereinheit so anzupassen, dass der Wert für den maximal zulässigen Strom für die elektrische Verbrauchereinheit erreicht wird. Damit kann eine Überlastung der elektrischen Sicherung sicher vermieden werden. Damit kann eine Sicherheitsreserve für den Strom durch die elektrische Sicherung zur Verfügung stehen. Des Weiteren kann die zur Verfügung stehende Ladeleistung sehr gut genutzt werden. Umfasst die elektrische Verbrauchereinheit einen Akkumulator, so kann damit die Ladezeit zum Laden des Akkumulators klein gehalten werden.According to a second aspect, the invention is characterized by a charging device, with a communication interface, which is designed to receive a value that is representative of a current additional current value by which the current through an electrical fuse can be maximally increased without triggering the electrical fuse and a processing unit configured to adjust a current for an electrical load unit depending on the value representative of the current boost current value. Such a charging device makes it possible to adjust the current for the electrical consumer unit so that the value for the maximum allowable current for the electrical consumer unit is reached. Thus, an overload of the electrical fuse can be safely avoided. This can provide a safety reserve for the current through the electrical fuse. Furthermore, the available charging power can be used very well. If the electrical consumer unit comprises an accumulator, then the charging time for charging the accumulator can be kept small.
In einer vorteilhaften Ausgestaltung des zweiten Aspekts ist die Verarbeitungseinheit dazu ausgebildet, ein vorgegebenes Testmuster auf den Strom für die elektrische Verbrauchereinheit aufzuprägen, und im Falle einer Korrelation zwischen dem vorgegebenen Testmuster und an der Kommunikationsschnittstelle empfangenen Werten, die repräsentativ sind für den aktuellen Zusatzstromwert um den der Strom durch die elektrische Sicherung maximal erhöht werden kann ohne ein Auslösen der elektrischen Sicherung zu bewirken, darauf zu schließen, dass die Ladevorrichtung mit der elektrischen Sicherung elektrisch gekoppelt ist.In an advantageous embodiment of the second aspect, the processing unit is designed to impose a predetermined test pattern on the current for the electrical load unit, and in the case of a correlation between the predetermined test pattern and values received at the communication interface, which are representative of the current additional current value around the the current through the electrical fuse can be maximally increased without causing the electrical fuse to trip, suggesting that the charging device is electrically coupled to the electrical fuse.
