Abstract
Description
Die Erfindung betrifft ein Flurförderzeug mit einem elektrischen Antrieb, einer Batterie, einer elektrischen Steuerung und einer Batterieladevorrichtung.The Invention relates to an industrial truck with an electric drive, a battery, an electric Control and a battery charger.
Gattungsgemäße Flurförderzeuge werden vorzugsweise dort eingesetzt, wo größtmögliche Flexibilität beim Einsatz des Flurförderzeugs gewährleistet sein soll, da es zum Aufladen des Flurförderzeugs genügt, dieses an eine Steckdose anzuschließen und keine Ladestation mit einem fest installierten Ladegerät benötigt wird. Insbesondere bei kleineren Flurförderzeugen mit niedriger Batteriekapazität, die nicht im Dauerbetrieb stehen, ist diese Lösung verbreitet. Solche Flurförderzeuge sind im Bauraum zumeist sehr beschränkt und müssen kostengünstig herstellbar und betreibbar sein.Generic trucks are preferably used where maximum flexibility in use of the truck guaranteed should be, since it is sufficient to charge the truck, this to be connected to a power outlet and no charging station with a fixed charger is needed. Especially for smaller industrial trucks with low battery capacity, which are not in continuous operation, this solution is widespread. Such trucks are in the space usually very limited and must be inexpensive to produce and be operable.
Ein wichtiger Kostenfaktor beim Betrieb batteriebetriebener Flurförderzeuge sind die verwendeten Batterien. Dabei handelt es sich zumeist um Bleiakkumulatoren, bei denen sich durch unsachgemäße Lade- und Entladevorgänge im Vergleich zu optimal betriebenen Batterien eine erheblich niedrigere Lebensdauer und damit höhere Kosten ergeben können. Insbesondere Tiefentladungen sowie dauernde Überladung schädigen die Batterien. Um diese Schädigung zu vermeiden, werden in Flurförderzeugen nach dem Stand der Technik so genannte Batteriemanagementsysteme verwendet. Dabei handelt es sich um elektronische Vorrichtungen, die den Lade- und Entladevorgang der Batterien überwachen, indem beispielsweise Lade- und Entladeströme und -spannungen sowie die Batterietemperatur erfasst werden. Aus diesen Größen kann der augenblickliche Ladezustand der Batterie bestimmt werden. Auch die Zahl der Lade- und Entladevorgänge kann erfasst werden. Damit ist es möglich, den Lade- und Entladevorgang an den Zustand der Batterie anzupassen. Bei Flurförderzeugen mit Wechselbatterien sind diese Batteriemanagementsysteme zumeist als Bestandteil der Batterie ausgeführt, da sonst eine kontinuierliche Erfassung der Batteriedaten, beispielsweise beim Ladevorgang außerhalb des Flurförderzeugs, nicht möglich ist. Bei Fahrzeugen mit fest installierter Batterie wird diese nur ausgetauscht, wenn das Ende der Lebensdauer erreicht ist. Ein in die Batterie integriertes Batteriemanagementsystem muss dabei mit ausgetauscht werden, auch wenn dieses noch vollkommen funktionsfähig ist. Dadurch entstehen zusätzliche Kosten. Nachteilig beim Einsatz eines Batteriemanagementsystems sind insbesondere bei kleineren und selten verwendeten Flurförderzeugen mit fest installierter Batterie zudem der benötigte Bauraum zur Unterbringung des Systems sowie die höheren Herstellkosten.One important cost factor in the operation of battery-powered industrial trucks are the batteries used. These are mostly around Lead-acid batteries which cause improper charging and unloading operations compared to optimally operated batteries a significantly lower Lifetime and thus higher Costs can result. Deep discharges in particular, as well as continuous overcharging damage the Batteries. To this injury to avoid, are in forklifts after used in the prior art so-called battery management systems. These are electronic devices that the charging and Monitor discharging process of batteries, by, for example, charging and discharging currents and voltages and the Battery temperature are detected. From these sizes can the instantaneous State of charge of the battery can be determined. The number of charging and unloading operations can be detected. This makes it possible to load and unload to adapt to the condition of the battery. For industrial trucks with replaceable batteries, these battery management systems are mostly executed as part of the battery, otherwise a continuous Acquisition of battery data, for example when charging outside of the truck, not possible is. For vehicles with fixed battery, this only replaced when the end of life is reached. One in the Battery integrated battery management system must be replaced with it even if it is still fully functional. This creates additional Costs. Disadvantageous when using a battery management system especially for smaller and rarely used industrial trucks with fixed battery also the required space for housing of the system as well as the higher ones Production costs.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Flurförderzeug mit einem elektrischen Antrieb, einer Batterie, einer elektrischen Steuerung und einer Batterieladevorrichtung zu schaffen, das einen einfachen Aufbau besitzt, kostengünstig zu betreiben ist und eine effektive Überwachung der für die Lebensdauer der Batterie relevanten Größen ermöglicht. Relevante Daten sind der Lade- beziehungsweise Entladestrom und die Lade- beziehungsweise Entladespannung der Batterie, deren Temperatur und der Säuregehalt sowie bei aus mehreren Zellen aufgebauten Batterien die Teilspannungen einzelner Zellen oder von Gruppen von Zellen.Of the Invention is therefore the object of an industrial truck with an electric drive, a battery, an electric To provide control and a battery charger, the one has simple structure, is inexpensive to operate and effective monitoring the for the life of the battery relevant sizes allows. Relevant data is the charging or discharging current and the charging or discharging voltage the battery, its temperature and acidity as well as from several Cells constructed batteries the partial voltages of individual cells or groups of cells.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass für den Be- und Entladevorgang der Batterie relevante Daten in einer im Flurförderzeug von der Batterie getrennt angeordneten Vorrichtung sammelbar und/oder speicherbar sind. Somit sind die für die Überwachung der Batterie und deren optimalen Betrieb benötigten Daten an einer Stelle verfügbar. Beim Austausch einer alten oder defekten Batterie wird nur die eigentliche Batterie ersetzt.The The object is achieved in that for the Loading and unloading of the battery relevant data in a in Truck Collectible and / or arranged separately from the battery device are storable. Thus, those for monitoring the battery and their optimal operation needed Data available in one place. At the Replacing an old or defective battery will only be the real thing Battery replaced.
Es ist besonders vorteilhaft, wenn der Ladevorgang der Batterie anhand der gesammelten und/oder gespeicherten Daten steuerbar ist. Dadurch wird eine übermäßige Belastung der Batterie, beispielsweise durch Überladung oder zu hohe Ladeströme, vemieden.It is particularly advantageous when charging the battery based the collected and / or stored data is controllable. This will an excessive burden the battery, for example, by overcharging or excessive charging currents, avoided.
Es ist ebenfalls von besonderem Vorteil, dass der Entladevorgang der Batterie anhand der gesammelten und/oder gespeicherten Daten steuerbar ist. Eine beispielsweise durch Tiefentladung oder zu hohe Entladeströme verursachte übermäßige Belastung der Batterie wird so vermieden.It is also of particular advantage that the unloading of the Battery is controlled based on the collected and / or stored data. For example, by deep discharge or excessive discharge currents caused excessive load The battery is thus avoided.
