Abstract
Die Erfindung betrifft ein Verfahren zum Laden einer Batterie eines Fahrzeuges mithilfe eines Ladegerätes des Fahrzeuges, wobei die Batterie und das Ladegerät über ein gemeinsames Kühlsystem gekühlt werden, wobei eine Temperatur der Batterie ermittelt wird, wobei die Temperatur mit einem Grenzwert verglichen wird, wobei ein Wirkungsgrad des Ladegerätes reduziert wird, um mehr Verlustleistung beim Laden der Batterie zu erzeugen, wenn die Temperatur der Batterie unter dem Grenzwert liegt.The invention relates to a method for charging a battery of a vehicle by means of a charger of the vehicle, wherein the battery and the charger are cooled by a common cooling system, wherein a temperature of the battery is determined, wherein the temperature is compared with a limit value, wherein an efficiency of the charger is reduced to generate more power loss when charging the battery when the temperature of the battery is below the limit.
Description
Die Erfindung betrifft ein Verfahren zum Laden einer Batterie eines Fahrzeuges gemäß Patentanspruch 1, ein Ladegerät gemäß Patentanspruch 6 und ein Fahrzeug mit einem Ladegerät gemäß Patentanspruch 12. The invention relates to a method for charging a battery of a vehicle according to claim 1, a charger according to claim 6 and a vehicle with a charger according to
Aus
Die Aufgabe der Erfindung besteht darin, ein verbessertes Verfahren und ein verbessertes Ladegerät zum Laden der Batterie des Fahrzeuges bereitzustellen. The object of the invention is to provide an improved method and an improved charger for charging the battery of the vehicle.
Die Aufgabe der Erfindung wird durch das Verfahren gemäß Patentanspruch 1, durch das Ladegerät gemäß Patentanspruch 6 und durch das Fahrzeug gemäß Patentanspruch 12 gelöst. The object of the invention is achieved by the method according to claim 1, by the charger according to claim 6 and by the vehicle according to
Vorteilhafte Ausführungsformen sind in den abhängigen Ansprüchen angegeben. Advantageous embodiments are given in the dependent claims.
Ein Vorteil des beschriebenen Verfahrens und des Ladegerätes besteht darin, dass die Batterie ohne Zusatzaufwand erwärmt werden kann, wenn die Temperatur zum Laden der Batterie unter einem vorgegebenen Grenzwert liegt. Dieser Vorteil wird dadurch erreicht, dass die Verlustleistung des Ladegerätes absichtlich erhöht wird, um die Batterie wenigstens nicht weiter abzukühlen bzw. um die Batterie zu erwärmen. Dazu ist das Ladegerät mit dem gleichen Kühlsystem wie die Batterie verbunden. Durch die Erhöhung der Verlustleistung des Ladegeräts wird vom Ladegerät Verlustwärme an das Kühlsystem abgegeben. Da die Batterie mit dem gleichen Kühlsystem gekoppelt ist, wird eine Erhöhung der Temperatur der Batterie erreicht. An advantage of the described method and the charger is that the battery can be heated without additional effort when the temperature for charging the battery is below a predetermined limit. This advantage is achieved in that the power loss of the charger is intentionally increased to at least not further cool the battery or to heat the battery. For this purpose, the charger is connected to the same cooling system as the battery. By increasing the power dissipation of the charger, the charger discharges heat loss to the cooling system. Since the battery is coupled to the same cooling system, an increase in the temperature of the battery is achieved.
In einer Ausführungsform wird das Ladegerät von einer externen Stromquelle mit Strom versorgt. Auf diese Weise ist es möglich, die Verlustwärme zum Erwärmen der Batterie von der externen Stromquelle zu beziehen. Somit wird die Ladung der Batterie des Fahrzeuges geschont. In one embodiment, the charger is powered by an external power source. In this way, it is possible to obtain the waste heat for heating the battery from the external power source. Thus, the charge of the battery of the vehicle is spared.
In einer weiteren Ausführungsform wird ein effizienter Einsatz des Ladegerätes zum Erwärmen der Batterie erreicht. Dies wird dadurch möglich, dass bei steigender Temperatur der Batterie die Verlustleistung des Ladegerätes reduziert wird. Somit wird eine unnötige Erzeugung von Verlustwärme durch das Ladegerät vermieden. Bei steigender Temperatur der Batterie, insbesondere bei Überschreiten der Grenztemperatur, ist es weniger bzw. nicht mehr erforderlich, dass das Ladegerät zusätzliche Verlustwärme an das Kühlsystem abgibt. In another embodiment, an efficient use of the charger for heating the battery is achieved. This is made possible by the fact that with increasing temperature of the battery the power loss of the charger is reduced. Thus, unnecessary generation of heat loss by the charger is avoided. As the temperature of the battery rises, in particular when the limit temperature is exceeded, it is less or no longer necessary for the charger to deliver additional heat loss to the cooling system.
In einer weiteren Ausführungsform weist das Ladegerät einen Gleichrichter und einen Gleichspannungswandler auf. Abhängig von der gewählten Ausführungsform kann der Wirkungsgrad des Gleichrichters und/oder der Wirkungsgrad des Gleichspannungswandlers zur Erzeugung der Verlustwärme verändert werden. In a further embodiment, the charger has a rectifier and a DC-DC converter. Depending on the selected embodiment, the efficiency of the rectifier and / or the efficiency of the DC-DC converter for generating the heat loss can be changed.
In einer weiteren Ausführungsform wird der Wirkungsgrad des Ladegerätes durch eine Änderung einer Stromsollwertvorgabe eines Wechselstromeinganges und/oder durch eine Änderung einer Spannungsvorgabe des Wechselstromeinganges und/oder durch eine Änderung einer Stromsollwertvorgabe eines Gleichspannungsausganges und/oder eine Änderung einer Spannungsvorgabe des Gleichspannungsausganges und/oder eine Änderung einer Schaltfrequenz des Gleichspannungswandlers und/oder eine Änderung einer Resonanzfrequenzvorgabe des Gleichspannungswandlers erreicht. Abhängig vom gewählten Ausführungsbeispiel können eine oder mehrere der genannten Parameter zur Erhöhung der Verlustwärme des Ladegerätes geändert werden. In a further embodiment, the efficiency of the charger by changing a current setpoint input of an AC input and / or by changing a voltage specification of the AC input and / or by changing a current setpoint specification of a DC voltage output and / or a change in a voltage specification of the DC voltage output and / or a change a switching frequency of the DC-DC converter and / or a change of a resonance frequency specification of the DC-DC converter achieved. Depending on the selected embodiment, one or more of the mentioned parameters for increasing the heat loss of the charger can be changed.

Mit dem beschriebenen System kann beispielsweise ein Leistungskorrekturfilter des Ladegerätes und/oder eine Gleichspannungswandlerstufe derart angesteuert werden, dass bei einer vorgegebenen Ladeleistung bei tiefen Außentemperaturen der Batterie
Bei tiefen Außentemperaturen wird die Batterie nur mit einer relativ niedrigen Ladeleistung, zum Beispiel 5 Ampere, über das Ladegerät geladen, da die Batterie auch nur eine der niedrigen Außentemperatur entsprechende Temperatur aufweist. Bei solch niedrigen Ladeleistungen weist jedoch das Ladegerät nur eine relativ geringe Verlustleistung auf. Wenn nun das Kühlsystem betrieben wird, kann sich in Summe eine Kühlung der Batterie ergeben. Dies würde zu einer Verlängerung der Ladedauer führen. At low outside temperatures, the battery is only charged with a relatively low charging power, for example 5 amperes, via the charger since the battery only has a temperature corresponding to the low outside temperature. At such low charging power, however, the charger has only a relatively low power loss. Now, if the cooling system is operated, the cooling of the battery can result in total. This would lead to an extension of the charging time.
