Definitions

  • the invention relates to a charging or discharging station for a redox flow-through battery, with a number of flow-through cells, each consisting of two half-cells that can be flowed through by differently charged electrolyte liquids and separated by means of a selectively ion-permeable membrane, in each of which an electrode is arranged, which is electrically connected to the electrode of another cell or to an external connection.
  • Arrangements of the type mentioned are known, for example, from DE 29 27 868 AI or also WO 00/57507 AI and use electro-chemical reduction and oxidation processes for storing and releasing electrical energy, which are essentially in the liquid phase using soluble salts of Metals that have different oxidation states run off.
  • chrome redox batteries, iron-titanium redox batteries or, more recently, vanadium redox batteries (VRB) are known, which have now reached technologically and structurally mature stages and are used in practical use, for example for temporary storage in photovoltaic systems.
  • Redox batteries of this type have the serious advantage that the underlying electrochemical reactions take place completely in the solutions themselves, and thus no chemical compounds are deposited on or in the electrodes or are detached from them during charging or discharging. This makes it possible, for example, to charge the battery by simply and quickly replacing the otherwise charged electrolyte liquids, which also allows the use of batteries of this type in vehicles which, like the conventional filling stations, can also be charged at electrolyte filling stations.
  • the storage capacity of such redox batteries can be influenced in the simplest way via the volume of the available electrolyte solutions, the available discharge voltage and output being easily influenced via the cell size and number of interconnected cells.
  • Electrodes to be assigned to adjacent flow cells in the partition are themselves electrically conductive connections created by overlapping continuous electrically conductive fibers. In this way, too, there is an electrical series connection of a large number of flow cells which can be selected within wide limits, which makes it possible to select discharge voltages in a very simple manner.
  • the present invention now takes a different approach. It is based on the consideration that the requirements for a charging station for redox flow batteries can usually be met much better and more simply by connecting the individual flow cells in parallel, while in most cases it is simpler and more advantageous for the discharge station for the electrical ones Series connection of the cells remain.
  • the addressed electrically conductive connection of at least some of the electrodes via interposed switching elements which selectively connect parallel or series electrical connection of at least individual groups of cells enable, runs, which enables a very advantageous influence on the characteristics of the battery or the adaptation to the respective use of the cell network (for charging or discharging).
  • This allows the current and voltage to be adapted to the respective needs in the simplest way, both when charging and discharging the battery.
  • the parallel connection of all individual cells results, for example, in a charge or discharge voltage corresponding to the individual cell with a correspondingly multiplied charge or discharge current - the groupwise or parallel connection which is possible in groups enables a wide variety of gradations to be made between maximum voltage and maximum current.
  • Individual cells or even cell groups can be monitored very easily in the parallel connection, with which, for example, defective individual cells or cell groups can be recognized and taken into account. Local overloading of individual cells and thus dangerous gas development can occur This prevents them, which increases the lifespan and the security of the system.
  • the switching elements have a switching position in which at least individual connections of the electrodes are open. With these opened connections, for example, the self-discharges via the electrolyte fluids which are otherwise inevitable when such redox flow-through batteries are in the idle state, since there is no longer an electrically conductive connection between the electrodes of different electrolyte spaces.
  • the cell contents were shut off in an electrically insulating manner from the remaining electrolyte volume during standstill, so that this self-discharge was limited to the cell contents.
  • FIG. 1 shows a redox flow-through battery according to the known prior art
  • FIGS. 2 to 4 each show only the most essential components of a charging or discharging station for such a battery in an exemplary embodiment according to the present invention.
  • the redox flow battery according to FIG. 1 (for example a vanadium redox battery) has four flow cells 1, each of which consists of two half cells 3, 4 which can be flowed through by differently charged electrolyte liquids and separated by means of a selectively ion-permeable membrane 2.
  • each of the half cells 3, 4 there is in each case an electrode 5, 6 which is electrical in the manner explained in more detail below is conductively connected to the electrode 6, 5 of another cell or to an external connection (+ or - at the top in FIG. 1).
  • the electrolyte liquids (corresponding to the anode and cathode also referred to as a ⁇ olyte and catholyte) are stored in containers 7, 8 (the volume of which determines the storage capacity of the battery) and are fed via lines 9, 10 and pumps 11, if necessary, via the respective half cells 3 , 4 is circulated, the electrochemical reduction or oxidation processes which cause the storage or release of the electrical energy to take place (see, for example, the explanations in the aforementioned DE 29 27 868 A1).
  • the further electrodes 5, 6, respectively assigned to the half cells are arranged on bipolar partition walls 14, with flow between the two adjoining one another Electrodes to be assigned to cells are created via the partition 14 even electrically conductive connections. This results in an electrical series connection of all (in the example four) flow cells 1, the total voltage between the connections + and - (lines 12 and 13) corresponding to the sum of the individual cell voltages, which in turn depends on the redox potential of the respective redox partner depend.
  • the electrically conductive connection 15 at least some of the elec- trodes 5, 6 runs through interposed switching elements 16, which enable the optional electrical parallel (Fig. 3) or series connection (Fig. 2) at least individual groups of cells 1 or according to Fig. 4 can also have a switching position in which at least individual connections 15 of the electrodes 5, 6 are open at all.
  • the switching elements 16 (which can be imagined in FIG. 2 as two switching bridges lying in parallel and rotatable by one end point each) are now switched so that each electrode 5 with the plus connection and each electrode 6 with the minus connection in Connection is established, with which an electrical parallel connection is realized and the total voltage corresponds to that of a single flow cell.
  • the switching elements 16 are in the open position, the individual electrodes 6, 7 being potential-free, which prevents the electrolyte liquids from self-discharging.
  • the switching elements 16 or their attachment in the electrical connections 15 between the electrodes 5, 6 can be freely selected within wide limits - in particular, semiconductor switching elements, electronic switches such as IGBTs, Mosfets, electrical ones, for example Relays or transistors, are used and also controlled by an electronic feedback / control system. Apart from that, manually operated switches (cells are manually switched to parallel or serial operation) would also be possible.

Dans chaque demi-cellule (3, 4) se trouve respectivement une électrode (5, 6) qui est reliée de manière électriquement conductrice à l'électrode d'une autre cellule (1) ou à une connexion extérieure (+, -). Afin de permettre la régulation du courant et de la tension de charge ou de décharge pour le fonctionnement respectif, la liaison électriquement conductrice (15) d'au moins l'une des électrodes (5, 6) se fait par l'intermédiaire d'éléments de commutation (16) intercalés qui permettent le branchement parallèle ou série au moins de groupes individuels de cellules (1).
