Description
Die Erfindung betrifft ein Energiespeichermodul und einen elektrischer Energiespeicher.The invention relates to an energy storage module and an electrical energy storage.
Der Erfindung liegt die Aufgabe zugrunde, ein Energiespeichermodul und einen elektrischen Energiespeicher zur Verfügung zu stellen, die eine möglichst flexible und zuverlässige Realisierung von elektrischen Energiespeichern ermöglichen.The invention has for its object to provide an energy storage module and an electrical energy storage available that allow the most flexible and reliable realization of electrical energy storage.
Die Erfindung löst diese Aufgabe durch ein Energiespeichermodul nach Anspruch 1 und einen elektrischer Energiespeicher nach Anspruch 6.The invention solves this problem by an energy storage module according to claim 1 and an electrical energy storage device according to claim 6.
Das Energiespeichermodul weist eine Energiespeichermodulzelle zum Speichern von, insbesondere elektrischer, Energie auf.The energy storage module has an energy storage module cell for storing, in particular electrical, energy.
Das Energiespeichermodul weist weiter eine Energiespeichermodulsteuereinheit auf, beispielsweise in Form eines Mikrocontrollers, zugehöriger Software und Peripheriebeschaltung. Die Energiespeichermodulsteuereinheit ist dazu ausgebildet, Betriebsparameter der Energiespeichermodulzelle eigenständig zu ermitteln und in Abhängigkeit von den ermittelten Betriebsparametern den Betrieb des Energiespeichermoduls eigenständig, und insbesondere unabhängig von einer zentralen Steuereinheit, zu steuern.The energy storage module further has an energy storage module control unit, for example in the form of a microcontroller, associated software and peripheral circuitry. The energy storage module control unit is designed to independently determine operating parameters of the energy storage module cell and to control the operation of the energy storage module independently, and in particular independently of a central control unit, in dependence on the determined operating parameters.
Jedes einzelne Energiespeichermodul ist autark und nicht abhängig von nach- oder vorgeschalteten Energiespeichermodulen. Auch ist die Arbeitsweise eines jeweiligen Energiespeichermoduls nicht von einer zentralen Steuerung abhängig. Jeder Zellebene (beispielsweise xP, 1S) bzw. Energiespeichermodulzelle wird genau eine Energiespeichermodulsteuereinheit zugeordnet und bildet mit dieser das Energiespeichermodul.Each individual energy storage module is self-sufficient and not dependent on upstream or upstream energy storage modules. Also, the operation of each energy storage module is not dependent on a central controller. Each cell level (for example xP, 1S) or energy storage module cell is assigned exactly one energy storage module control unit and forms with it the energy storage module.
Die Energiespeichermodulzelle und die Energiespeichermodulsteuereinheit können in einem gemeinsamen Gehäuse angeordnet sein.The energy storage module cell and the energy storage module control unit may be arranged in a common housing.
Ein jeweiliges Energiespeichermodul bzw. dessen Energiespeichermodulsteuereinheit kann die vollständige und eigenständige Überwachung der zugeordneten Zellebene bzw. Energiespeichermodulzelle bezüglich Überspannung, Unterspannung und ggf. auch noch Temperatur übernehmen.A respective energy storage module or its energy storage module control unit can take over the complete and independent monitoring of the assigned cell level or energy storage modulator cell with respect to overvoltage, undervoltage and possibly even temperature.
Die Kommunikation zu einer zentralen Überwachungseinheit kann über nur eine oder zwei Leitungen erfolgen. Es können Messdaten zur Überwachung und ggf. auch ein Statussignal übertragen werden, das der redundanten Überwachung von sicherheitsrelevanten Zuständen dient.Communication to a central monitoring unit can take place via only one or two lines. Measurement data for monitoring and possibly also a status signal can be transmitted, which serves for the redundant monitoring of safety-relevant states.
Die erfindungsgemäßen Energiespeichermodule mit Eigenintelligenz auf Modulbasis sind beliebig, insbesondere seriell, verschaltbar, ohne dass für eine spezifische Verschaltung eine spezifische Elektronik entwickelt werden muss. Die Energiespeichermodule bilden einen modularen Baukasten, der praktisch beliebig skaliert „zusammensteckbar“ ist, um flexibel und schnell praktisch beliebige elektrische Energiespeicher bzw. Batteriemodule zu implementieren.The energy storage modules according to the invention with inherent intelligence on a module basis are arbitrary, in particular serial, interconnectable, without having to develop specific electronics for a specific interconnection. The energy storage modules form a modular construction kit that can be "scaled up" to practically any size in order to flexibly and quickly implement practically any desired electrical energy storage or battery modules.
Ein weiterer Vorteil ist die Verringerung des Verkabelungsaufwandes aufgrund der dezentralen Auswertung der vor Ort (direkt an der Zelle) gewonnenen Daten.Another advantage is the reduction of the cabling effort due to the decentralized evaluation of the data obtained locally (directly at the cell).
Die Energiespeichermodulzelle kann eine einzelne elektrochemische Zelle oder mehrere parallel geschaltete elektrochemische Zellen aufweisen bzw. sein, wie beispielsweise solche, die auf Blei oder auf Lithium-Nickel basieren. Auch sind Energiespeichermodulzellen denkbar, die auf Kondensatortechnologien basieren.The energy storage modulator cell may comprise a single electrochemical cell or a plurality of parallel connected electrochemical cells, such as those based on lead or lithium-nickel. Also, energy storage modulator cells based on capacitor technologies are conceivable.
Die Energiespeichermodulsteuereinheit kann dazu ausgebildet sein, Betriebsparameter in Form einer Temperatur der Energiespeichermodulzelle, und/oder einer Spannung der Energiespeichermodulzelle, und/oder eine Anzahl von Ladezyklen der Energiespeichermodulzelle, und/oder einen Ladezustand der Energiespeichermodulzelle zu ermitteln.The energy storage module control unit may be configured to determine operating parameters in the form of a temperature of the energy storage modulator cell, and / or a voltage of the energy storage modulator cell, and / or a number of charge cycles of the energy storage modulator cell, and / or a state of charge of the energy storage modulator cell.
Die Energiespeichermodulsteuereinheit kann dazu ausgebildet sein, in Abhängigkeit von den ermittelten Betriebsparametern unter anderem eine Ladesteuerung, und/oder eine Ladeendabschaltung, ein Lade-Balancing, und/oder einen Überhitzungsschutz durchzuführen.The energy storage module control unit may be designed to perform, inter alia, a charge control, and / or a charge end cutoff, a charge balancing, and / or an overheat protection depending on the determined operating parameters.
Das Energiespeichermodul kann eine, insbesondere galvanisch trennende, Datenübertragungsschnittstelle aufweisen, mittels der die ermittelten Betriebsparameter zu einer zentralen Überwachungseinheit übertragbar sind.The energy storage module can have a, in particular galvanically separating, data transmission interface by means of which the determined operating parameters can be transmitted to a central monitoring unit.
Der elektrische Energiespeicher weist eine Anzahl, beispielsweise zwischen 2 und 200, von Energiespeichermodulen auf.The electrical energy store has a number, for example between 2 and 200, of energy storage modules.
Die Energiespeichermodule können in Reihe geschaltet sein.The energy storage modules can be connected in series.
Der elektrische Energiespeicher kann eine zentrale Überwachungseinheit aufweisen, wobei die zentrale Überwachungseinheit eine Datenübertragungsschnittstelle zur Kopplung mit den jeweiligen Datenübertragungsschnittstellen der Energiespeichermodule aufweist.The electrical energy store may have a central monitoring unit, wherein the central monitoring unit has a data transmission interface for coupling to the respective data transmission interfaces of the energy storage modules.
Der elektrische Energiespeicher kann einen Zentralschalter aufweisen, der von der zentralen Überwachungseinheit angesteuert ist und der in Reihe mit der Anzahl von Energiespeichermodulen zwischen ein Betriebspotential und ein Bezugspotential eingeschleift ist. Auf diese Weise kann beispielsweise eine Sicherheitsabschaltung erfolgen, wenn die Betriebsdaten mindestens eines Energiespeichermoduls einen kritischen Zustand anzeigen.The electrical energy store may have a central switch, which is controlled by the central monitoring unit and which is looped in series with the number of energy storage modules between an operating potential and a reference potential. In this way, for example, a safety shutdown occur when the operating data of at least one energy storage module indicate a critical condition.
