Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren zum Laden eines elektrochemischen Energiespeichers, insbesondere einer Batterie, umfasst das Erfassen eines ersten Eingabesignals, das Erfassen eines zweiten Eingabesignals, das Bestimmen eines Istladezustands des elektrochemischen Energiespeichers und das Erfassen einer Anfangstemperatur des elektrochemischen Energiespeichers. Das Verfahren umfasst außerdem das Bestimmen eines Temperaturhubs in Abhängigkeit einer vorgegebenen Betriebsdauer und mindestens eines weiteren Parameters, sowie das Bestimmen einer Endtemperatur des elektrochemischen Energiespeichers, wobei die Endtemperatur eine Differenz einer maximal zulässigen Temperatur des elektrochemischen Energiespeichers und des Temperaturhubs ist. Das Verfahren umfasst weiterhin das Erzeugen eines Ladesignals in Abhängigkeit der Anfangstemperatur des elektrochemischen Energiespeichers, der Endtemperatur des elektrochemischen Energiespeichers, des ersten Eingabesignals, des zweiten Eingabesignals und des Istladezustands des elektrochemischen Energiespeichers, wobei das Ladesignal einen Ladestrom umfasst, und das Ansteuern einer Ladevorrichtung mittels Ladesignal zum Laden des elektrochemischen Energiespeichers.The method according to the invention for charging an electrochemical energy store, in particular a battery, comprises detecting a first input signal, detecting a second input signal, determining an actual charge state of the electrochemical energy store and detecting an initial temperature of the electrochemical energy store. The method also includes determining a temperature swing as a function of a predetermined operating time and at least one further parameter, and determining a final temperature of the electrochemical energy store, wherein the end temperature is a difference between a maximum allowable temperature of the electrochemical energy store and the temperature. The method further comprises generating a charge signal as a function of the initial temperature of the electrochemical energy store, the final temperature of the electrochemical energy store, the first input signal, the second input signal and the actual state of charge of the electrochemical energy store, wherein the charge signal comprises a charging current, and the driving of a charging device by means of a charging signal for charging the electrochemical energy store.
Der Vorteil ist hierbei, dass der elektrochemische Energiespeicher unmittelbar nach dem Beenden des Ladevorgangs einsetzbar ist.The advantage here is that the electrochemical energy store can be used immediately after the end of the charging process.
In einer Weiterbildung repräsentiert das erste Eingabesignal einen Nutzungszeitpunkt des elektrochemischen Energiespeichers. Mit anderen Worten es handelt sich hierbei um den Zeitpunkt an dem der elektrochemische Energiespeicher verwendet werden bzw. gestartet werden soll.In a further development, the first input signal represents a time of use of the electrochemical energy store. In other words, this is the point in time at which the electrochemical energy store is used or should be started.
In einer weiteren Ausgestaltung repräsentiert das zweite Eingabesignal einen Sollladezustand des elektrochemischen Energiespeichers zum Nutzungszeitpunkt. Mit anderen Worten es handelt sich hierbei um einen vom Nutzer gewünschten Ladezustand des elektrochemischen Energiespeichers zum Nutzungszeitpunkt.In a further refinement, the second input signal represents a nominal charging state of the electrochemical energy store at the time of use. In other words, this is a charge state of the electrochemical energy store desired by the user at the time of use.
In einer Weiterbildung ist der mindestens eine weitere Parameter ein konstant entnehmbarer maximaler Entladestrom des elektrochemischen Energiespeichers oder ein entnehmbarer Entladestrom, der aus einer bisherigen Verwendungsweise des elektrochemischen Energiespeichers bestimmt wird.In a development, the at least one further parameter is a constantly removable maximum discharge current of the electrochemical energy store or a removable discharge current, which is determined from a previous mode of use of the electrochemical energy store.
Der Vorteil ist hierbei, dass der Ladevorgang des elektrochemischen Ladevorgangs an die anschließende Verwendungsweise des Nutzers angepasst werden kann.The advantage here is that the charging of the electrochemical charging can be adapted to the subsequent use of the user.
In einer Weiterbildung wird ein Alterungszustand des elektrochemischen Energiespeichers bestimmt und das Ladesignal in Abhängigkeit des Alterungszustands des elektrochemischen Energiespeichers eingestellt.In a development, an aging state of the electrochemical energy store is determined and the charging signal is set as a function of the aging state of the electrochemical energy store.
Vorteilhaft ist hierbei, dass durch den angepassten Ladestrom die Alterung beeinflusst werden kann. Somit kann beispielsweise eine fortschreitende Alterung durch langsames Laden verringert werden. Es ist jedoch auch möglich bei definierter verbleibender Lebensdauer der Batterie, z.B. bis zum terminierten Tausch der Batterie, einen höheren Ladestrom zu verwenden und damit die Ladezeit zu reduzieren.It is advantageous here that the aging can be influenced by the adapted charging current. Thus, for example, progressive aging can be reduced by slow charging. However, it is also possible with a defined remaining life of the battery, e.g. until the battery is replaced at the scheduled time, to use a higher charge current and thus to reduce the charging time.
In einer weiteren Ausgestaltung wird der Ladestrom auf einen maximal zulässigen Ladestrom des elektrochemischen Energiespeichers begrenzt.In a further embodiment, the charging current is limited to a maximum permissible charging current of the electrochemical energy store.
Der Vorteil ist hierbei, dass der elektrochemische Energiespeicher durch den Ladevorgang nicht zerstört werden kann.The advantage here is that the electrochemical energy storage can not be destroyed by the charging process.
In einer Weiterbildung wird ein Informationssignal insbesondere zum Zeitpunkt eines Ladebeginns erzeugt. Das Informationssignal gibt an, dass ein tatsächlicher Ladezustand des elektrochemischen Energiespeichers zum Nutzungszeitpunkt kleiner sein wird als der Sollladezustand, d. h. der vom Nutzer gewünschte Ladezustand.In one development, an information signal is generated in particular at the time of starting charging. The information signal indicates that an actual state of charge of the electrochemical energy storage at the time of use will be smaller than the nominal state of charge, ie the desired state of charge by the user.
Vorteilhaft ist hierbei, dass ein Nutzer über den tatsächlichen Ladezustand zum Nutzungszeitpunkt bei Ladebeginn informiert werden kann. Dadurch erhält der Nutzer die Möglichkeit seine Eingaben bezüglich des Nutzungszeitpunkts und des gewünschten Ladezustands gegebenenfalls anzupassen.It is advantageous here that a user can be informed about the actual state of charge at the time of use at the start of charging. This gives the user the opportunity to adjust his inputs regarding the time of use and the desired state of charge, if necessary.
In einer weiteren Ausgestaltung wird das Informationssignal auf einem HMI des elektrochemischen Energiespeichers, einem HMI eines Fahrzeugs oder einem mobilen Endgerät angezeigt bzw. ausgegeben.In a further refinement, the information signal is displayed or output on an HMI of the electrochemical energy store, an HMI of a vehicle or a mobile terminal.
Das erfindungsgemäße Batteriemanagementsystem umfasst eine Steuereinheit und einen Speicher, wobei das Batteriemanagementsystem eingerichtet ist, das erfindungsgemäße Verfahren auszuführen.The battery management system according to the invention comprises a control unit and a memory, wherein the battery management system is set up to carry out the method according to the invention.
Das erfindungsgemäße Batteriesystem umfasst mindestens einen elektrochemischen Energiespeicher und ein erfindungsgemäßes Batteriemanangementsystem.The battery system according to the invention comprises at least one electrochemical energy store and a battery management system according to the invention.
In einer Weiterbildung umfasst der elektrochemische Energiespeicher Li-Ionen-Zellen, LiS-Zellen, LiO-Zellen oder Feststoffzellen.In a development, the electrochemical energy store comprises Li-ion cells, LiS cells, LiO cells or solid cells.
Erfindungsgemäß wird das Batteriesystem in einem Fahrzeug verwendet.According to the invention, the battery system is used in a vehicle.
In einer Weiterbildung ist das Fahrzeug ein elektrisch betriebenes Zweirad, insbesondere ein Roller.In a further development, the vehicle is an electrically operated two-wheeler, in particular a scooter.

In einem weiteren Ausführungsbeispiel wird ein Informationssignal erzeugt, wenn der Ladestrom durch den maximal zulässigen Ladestrom begrenzt wird. Das Informationssignal repräsentiert die Information, dass der tatsächliche Ladezustand der Batterie zum Nutzungszeitpunkt kleiner ist als der vom Nutzer gewünschte Ladezustand. Dieses Informationssignal kann zum Zeitpunkt des Ladestarts beispielsweise auf einem Display des elektrochemischen Energiespeichers, einem Display eines Fahrzeugs oder dem mobilen Endgerät angezeigt werden.In a further embodiment, an information signal is generated when the charging current is limited by the maximum allowable charging current. The information signal represents the information that the actual state of charge of the battery at the time of use is less than the state of charge desired by the user. This information signal can be displayed at the time of the charging start, for example, on a display of the electrochemical energy storage, a display of a vehicle or the mobile terminal.
Alternativ kann eine verbleibende Ladezeit bis zum Erreichen des ersten Ladezustand und ein aktueller Ladezustand angezeigt werden.Alternatively, a remaining charging time until reaching the first state of charge and a current state of charge can be displayed.

Das elektrisch betriebene Fahrzeug kann ein Zweirad sein, insbesondere ein Roller.The electrochemical energy storage is used for example in an electrically powered vehicle application. The electrically powered vehicle may be a two-wheeler, in particular a scooter.
Das Verfahren kann auch für andere elektrisch betriebene Systeme und Geräte verwendet werden, wenn diese direkt nach dem Laden verwendet werden sollen. Die vorliegende Erfindung optimiert das Laden also auf die im unmittelbaren Anschluss an den Ladevorgang oder in absehbarer Zeit geplante Nutzung des Systems, Gerätes oder Fahrzeug.The method can also be used for other electrically operated systems and devices if they are to be used directly after charging.
