Description
Die Erfindung betrifft ein Energiemanagementsystem zur Energieversorgung eines elektrisch betriebenen Fahrzeugs mit einer ersten Batterie, welche zumindest ein erstes und ein zweites Batteriemodul umfasst, wobei die zumindest zwei Batteriemodule austauschbar sind.The invention relates to an energy management system for supplying energy to an electrically operated vehicle having a first battery, which comprises at least a first and a second battery module, wherein the at least two battery modules are interchangeable.
Bei einem Elektrofahrzeug ist die maximale Reichweite der möglichen Fahrstrecke durch die Batteriekapazität begrenzt. Einschränkend sind außerdem Faktoren wie zum Beispiel die Klimaanlage, da die Energie für das Betreiben der Klimaanlage aus der Fahrzeugbatterie gespeist wird.
Für den Nutzer ist es dadurch wichtig, dass in regelmäßigen Streckenabständen Ladestationen für Elektroautos bereitgestellt werden.In an electric vehicle, the maximum range of the possible route is limited by the battery capacity. Also limiting are factors such as the air conditioning, as the energy for operating the air conditioning system is supplied from the vehicle battery.
It is therefore important for the user that charging stations for electric cars are provided at regular distances.

Die
Die Energieübertragung wird über eine zentrale Einheit geregelt, welche mit den einzelnen Batterien verbunden ist.The energy transfer is controlled by a central unit, which is connected to the individual batteries.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Verschleiß bei austauschbaren Batteriemodulen zu reduzieren.The object of the present invention is to reduce wear on replaceable battery modules.
Die Aufgabe wird durch ein Energiemanagementsystem zur Energieversorgung eines elektrisch betriebenen Fahrzeugs nach Anspruch 1 gelöst. Sinnvolle Weiterbildungen und vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The object is achieved by an energy management system for supplying energy to an electrically operated vehicle according to
Ein Aspekt der Erfindung besteht darin, dass ein Energiemanagementsystem vorgesehen ist, zur Energieversorgung eines elektrisch betriebenen Fahrzeugs mit einer ersten Batterie, welche zumindest ein erstes und ein zweites Batteriemodul umfasst, wobei die zumindest zwei Batteriemodule austauschbar sind, wobei an jedem Batteriemodul eine induktive bidirektionale Ladeschnittstelle ausgebildet ist und die Batteriemodule einen unterschiedlichen Ladezustand aufweisen, wobei das erste Batteriemodul mit einem höheren Ladezustand dazu ausgebildet ist, das zweite Batteriemodul mit einem geringeren Ladezustand über die bidirektionalen induktiven Ladeschnittstellen induktiv zu laden. Die induktive bidirektionale Ladeschnittstelle wirkt wie ein Gleichspannungswandler. Die induktive bidirektionale Ladeschnittstelle ist für die Energieübertragung der einzelnen Batteriemodule zuständig, wobei jedes Batteriemodul mit einer eigenen induktiven bidirektionalen Ladeschnittstelle ausgestattet ist. Die induktive Ladeschnittstelle kann Signale in entgegengesetzte Richtungen übertragen. Jedes Batteriemodul ist einzeln mechanisch austauschbar, dies bedeutet, dass ein Nutzer nach Belieben die Batteriemodule einzeln herausnehmen und wieder einsetzen kann. Um eine höhere Reichweite des Elektrofahrzeugs zu schaffen, kann ein Nutzer ohne weiteres ein oder mehrere Batteriemodule an eine Fahrzeugbatterie anschließen. Die Batteriemodule können verschiedene Ladezustände aufweisen. Wenn ein Batteriemodul einen nur noch sehr geringen Ladezustand aufweist, kann das Batteriemodul mithilfe der induktiven bidirektionalen Ladeschnittstelle von einem anderen Batteriemodul, welches einen höheren Ladezustand aufweist, wieder aufgeladen werden. Hierbei werden die unterschiedlichen Ladezustände umgeladen. Es können beispielsweise mehrere Batteriemodule gleichzeitig umgeladen werden.One aspect of the invention is that an energy management system is provided for supplying power to an electrically powered vehicle having a first battery comprising at least a first and a second battery module, wherein the at least two battery modules are interchangeable, wherein an inductive bidirectional charging interface on each battery module is formed and the battery modules have a different state of charge, wherein the first battery module is formed with a higher state of charge to inductively charge the second battery module with a lower state of charge via the bidirectional inductive charging interfaces. The inductive bidirectional charging interface acts like a DC-DC converter. The inductive bidirectional charging interface is responsible for the energy transfer of the individual battery modules, whereby each battery module is equipped with its own inductive bidirectional charging interface. The inductive charging interface can transmit signals in opposite directions. Each battery module is individually mechanically interchangeable, meaning that a user can disassemble and replace the battery modules one at a time. To provide a greater range of the electric vehicle, a user can easily connect one or more battery modules to a vehicle battery. The battery modules can have different states of charge. If a battery module has a very low state of charge, the battery module can be recharged by means of the inductive bidirectional charging interface of another battery module, which has a higher state of charge. Here, the different states of charge are reloaded. For example, several battery modules can be reloaded at the same time.
Vorzugsweise ist vorgesehen, dass das erste und das zweite Batteriemodul jeweils mit einer Kommunikationsschnittstelle ausgebildet sind. Die Kommunikationsschnittstelle kann in dem Batteriemodul installiert sein und kann beispielsweise als eine Bluetooth-Verbindung oder ein WLAN-Verbindung ausgebildet sein. Die Kommunikationsschnittstelle kann beispielsweise mit der induktiven bidirektionalen Ladeschnittstelle verbunden sein. Es kann von der Kommunikationsschnittstelle beispielsweise ein geeignetes zweites Batteriemodul zum Umladen der Ladezustände ermittelt und an die induktive bidirektionale Ladeschnittstelle kommuniziert werden. Die Kommunikationsschnittstelle kann vorzugsweise den aktuellen Ladezustand des Batteriemoduls überprüfen.It is preferably provided that the first and the second battery module are each formed with a communication interface. The communication interface may be installed in the battery module and may be configured, for example, as a Bluetooth connection or a WLAN connection. The communication interface can be connected, for example, to the inductive bidirectional charging interface. It can be determined by the communication interface, for example, a suitable second battery module for reloading the charge states and communicated to the inductive bidirectional charging interface. The communication interface may preferably check the current state of charge of the battery module.
Weiterhin ist vorgesehen, dass eine Gesamtleistung der ersten Batterie bei einem Umladen der Ladezustände der einzelnen Batteriemodule unverändert ist. Die Gesamtleistung der Batteriemodule wird auf die einzelnen Batteriemodule verteilt. Während des Umladens der Ladezustände der Batteriemodule verhalten sich die Batteriemodule zueinander gegenläufig. Die induktive bidirektionale Ladeschnittstelle wirkt wie ein Gleichspannungswandler. Die von dem zweiten Batteriemodul zugeführte Gleichspannung wird in höhere Spannung umgewandelt und in das erste Batteriemodul, welches den niedrigeren Ladezustand aufweist, gespeist. Beispielsweise kann der Nutzer die Batteriemodule herausnehmen beziehungsweise austauschen, wenn eine höhere oder geringere Reichweite des Elektrofahrzeugs benötigt wird.Furthermore, it is provided that a total power of the first battery is unchanged when the charge states of the individual battery modules are recharged. The total power of the battery modules is distributed to the individual battery modules. During the recharge of the charge states of the battery modules, the battery modules behave in opposite directions. The inductive bidirectional charging interface acts like a DC-DC converter. The DC voltage supplied by the second battery module is converted into higher voltage and into the first battery module which has the lower one Charge state, fed. For example, the user can take out or replace the battery modules, if a higher or lower range of the electric vehicle is needed.
Vorzugsweise ist vorgesehen, dass die Batteriemodule zueinander in Serie oder parallel geschalten sind. Die Gesamtleistung der Batteriemodule bleibt bei beiden Schaltungsvarianten gleich, da sich die Gesamtleistung sowohl bei der Serienschaltung, als auch bei der Parallelschaltung aus den Teilleistungen der einzelnen Batteriemodule ergibt. Bei einer Serienschaltung wird eine hohe Spannung erzielt. Die Parallelschaltung bietet den Vorteil, dass bei einem Ausfallen eines Batteriemoduls die Gesamtspannung in den Batteriemodulen gleich bleibt.It is preferably provided that the battery modules are connected to each other in series or in parallel. The overall performance of the battery modules remains the same for both circuit variants, since the overall performance results both in the series connection, as well as in the parallel circuit of the partial power of the individual battery modules. In a series connection, a high voltage is achieved. The parallel connection has the advantage that when a battery module fails, the total voltage in the battery modules remains the same.
In einer sinnvollen Weiterbildung ist mit der Kommunikationsschnittstelle des ersten Batteriemoduls Auskunft über den Ladezustand des ersten Batteriemoduls an die zweite Kommunikationsschnittstelle des zweiten Batteriemoduls übertragbar. Die Kommunikationsschnittstelle, welche am Batteriemodul angeordnet sein kann, kann beispielsweise den aktuellen Ladezustand des zugehörigen Batteriemoduls überprüfen. Wenn der Ladezustand überprüft wurde und ein Umladen notwendig ist, kann ein geeignetes zweites Batteriemodul mit einem höheren Ladezustand ermittelt werden. Hierbei läuft die Kommunikation über die Kommunikationsschnittstellen der Batteriemodule ab.In a meaningful further development, information about the state of charge of the first battery module can be transmitted to the second communication interface of the second battery module with the communication interface of the first battery module. The communication interface, which can be arranged on the battery module, can check, for example, the current state of charge of the associated battery module. If the state of charge has been checked and a recharge is necessary, a suitable second battery module with a higher state of charge can be determined. In this case, communication takes place via the communication interfaces of the battery modules.
In einer Ausführungsform ist die erste Batterie zu einer zweiten Batterie parallel geschalten. Bei der zweiten Batterie kann es sich um eine Traktionsbatterie oder andere diverse Batterien, welche zum Antrieb eines elektrisch angetriebenen Fahrzeugs geeignet sind, handeln. Die erste Batterie weist die Batteriemodule auf und kann über ein kabelgebundenes Laden oder ein induktives Laden aufgeladen werden. Das elektrisch angetriebene Fahrzeug kann beispielsweise ein elektrisch angetriebenes Auto, ein Elektroroller oder ein Elektrobus sein. Beispielhaft können die Batteriemodule auch für ein Batteriemanagementsystem eines elektrisch betriebenen Fahrrads genutzt werden. Anhand der Verbindung zwischen der ersten Batterie und der zweiten Batterie wird mehr Leistung erzielt, wodurch eine höhere Reichweite erzielt werden kann.In one embodiment, the first battery is connected in parallel with a second battery. The second battery may be a traction battery or other various batteries suitable for driving an electrically powered vehicle. The first battery has the battery modules and can be charged via a wired charging or inductive charging. The electrically powered vehicle may be, for example, an electrically powered car, an electric scooter or an electric bus. By way of example, the battery modules can also be used for a battery management system of an electrically operated bicycle. The connection between the first battery and the second battery provides more power, allowing for longer range.
