Power source that can be assembled from accumulator batteries to equip for insertion of primary batteries in the form of single-cell electrical devices

Primary batteries, intended for single discharge, are currently being used for operating electrical devices of various types, e.g. portable radio receivers, flashlights, Radiotelephones, cassette recorders, small computers, toys and the like more annually in very large numbers consumed. Special designs with a circular cross-section, as they are according to different capacities and accordingly different sizes and with different types are on the market, are both individually and especially frequently in series connections of two to eight Single cells for equipping electrical devices, used. These are the electrical devices on the market

formed with a battery compartment that corresponds to the operating voltage corresponding number of the device and the type of single primary cells to be used for the required battery capacity is adapted.

There are a number of advantages of being able to easily procure such primary batteries, which are traded everywhere serious disadvantages: The service life of the primary batteries is only very limited. The fresh state the primary batteries can only be deficient, without any information about the service life; to be controlled. Despite all efforts it also failed to eliminate the possibility of battery leakage, the mostly destructive consequence for the device includes eliminating a certain amount of gas exchange with the outside air in primary batteries is inevitable. Another major disadvantage is that the primary batteries used up annually by tar tons of Zinc and its compounds occur in the form of uncontrollable, mostly carelessly thrown waste in the environment.

There is therefore a considerable need for accumulators that can be recharged instead of the primary batteries that have to be used only once to use for the operation of such devices. It has therefore not yet attempted to use such Accumulators in electrical devices are missing. So are maintenance-free lead accumulators in the form of e.g. mono cells

on the market, but because of the voltage difference there is no real compatibility with the single primary cell.

In a similar way, alkaline accumulators, usually of a gas-tight design, are already made in the same external form manufactured as the described primary batteries, but with also here because of the lower tension of an individual Accumulator of approx. 1.2 V compared to the usual terminal voltage of a primary cell of 1.5 V is a simple exchange not possible. Apart from this lack of adaptation, there is a multi-cell primary battery, for example from four mono cells, not for reasons of cost to be replaced by four accumulators of the same dimensions which leads to the recharging of the alkaline batteries of such capacity and for such an application special, not usable for other accumulator numbers Charger must be provided.

It is due to these disadvantages that previously rechargeable Small accumulators in large numbers only for higher quality electrical devices, e.g. Büfcz devices, radio ' Intercoms, remote control systems and the like are used, i.e. only for those devices in which the accumulators are fixed

integrated and equipped with a special charger. On the other hand, accumulators could be used as an exchange for exchangeable Primary batteries have not yet gained a foothold on the market.

In contrast, it is the object of the invention to provide one from accumulator batteries Composable power source for equipping for inserting primary batteries, in particular in the form of single cells aligned electrical devices, with which both the previously unbridgeable voltage gap between primary batteries and accumulators as well as the Difficulties in charging these accumulators are eliminated, and on the other hand also at a sufficiently low price can be produced in order to be able to take the place of primary batteries.

This object is achieved according to the invention in that for the total number of individual primary cells to be used in the respective device, only a small one, the operating voltage number of accumulator batteries of the respective device, preferably only one accumulator battery, and a corresponding remaining number of electrically conductive filler pieces are provided, both the accumulator batteries wöbe as well as the filler pieces in their external dimensions, shape and contact arrangement each of a single primary cell of the corresponding type, and that accumulators

gate batteries of various numbers of accumulator cells according to the different operating voltages battery operated electrical devices are provided.

The invention provides a system of accumulator batteries and filler pieces created, with a corresponding one electrical device as a rule - one at a time Operating voltage corresponding accumulator battery and for the remaining number of filler pieces are used. One might initially assume that this type of exchange power source even greater disadvantages than previous attempts, namely the replacement of the single primary cells by accumulator cells would bring with it. In fact, this is not the case the case because of the deliberate limitation of the capacity of the single primary cell in terms of dimensions and shape clustered accumulator battery is a more common one Charging is required, but a very simple one Charger can be used by using that today The usual current limiter is used very simply and cheaply to charge the accumulator batteries of the most varied of clamping voltages, which have the same external shape and dimensions can be. Another major advantage of the first The limitation of the battery capacity, which appears disadvantageous, is that this limited battery capacity is

sufficient to operate with a power source according to the invention to operate the equipped electrical device for a sufficient period of time, for example for a day, and that in the breaks in operation that exist with every electrical device, for example at night, a complete charging of a Accumulator battery of the limited capacity in such a way can be done. Even if the respective electrical Device should be in operation practically uninterrupted, there is still the simple possibility of the power source to be provided with two identical accumulator batteries, of which one is in operation and the other is charged will. The power source according to the invention also offers the particular advantage that throwing away items that have become unusable Batteries are not required. The filler pieces, which form the bulk of the power source, are practically never unusable. When an accumulator battery has been recharged many times becomes unusable, the substances it contains, e.g. nickel and cadmium, are still sufficient Material value that justifies chemical regeneration. Manufacturers and sellers can do that Grant buyers of an accumulator battery a sufficiently high reimbursement for the old accumulator battery, which prompts the buyer or user to return the old accumulator battery instead of throwing it away.

In a particularly advantageous embodiment of the invention, all accumulator batteries, regardless of their number of cells, built from accumulator cells of the same capacity. This offers the advantage that a single type of accumulator cells is used for all accumulator batteries of different clamping voltage, whereby the production of the Accumulator batteries is significantly cheaper. This also offers the opportunity for each of the Accumulator batteries regardless of their terminal voltage one and the same charger equipped with a current limiter to use. Since experience has shown that these accumulator batteries are not exhausted at the same time and therefore do not have to be charged at the same time, it is normally sufficient single charger for a large number of accumulator batteries.

In a preferred embodiment of the invention, the current source is therefore also equipped with an associated current limiter Charger provided that only has a small number of series-connected charging positions, but preferably only one has only one loading space. As provided within the scope of the invention is, usually an electrical device with a single accumulator battery and for the remaining number with filling

To equip pieces, you can usually get by with a charger with only one charging place. Exceptional cases for which a special charger with several charging stations connected in series could be desirable. An example for such an exceptional case it could be that electrical devices with a relatively high operating voltage, for example 24 V with, for example, two or three accumulator batteries connected in series (for example two accumulator batteries rien with 12 V terminal voltage each) and the remaining number of filler pieces be populated. In such a case it might be desirable. be able to recharge the batteries that have been in operation at the same time. Such a charger with several, but at least a small number, charging places can still be used for charging a smaller one Use the number of accumulator batteries when you go to the unused cargo space with what belongs to the system Filler piece occupied. However, within the scope of the invention, it should be irrelevant whether the charger contains one or more charging places, It must be guaranteed that the charger is not only filled with fillers or even with primary cells and put into operation can be. This is achieved according to the invention in that in a charging station or the only charging station of the charger additional locks are arranged, which are attached to each accumulator battery with corresponding input

directions fit together. This ensures that a charging station or the only charging station of the charger can only be occupied by one accumulator battery. For example, in the context of the invention, the lock on the one con. be arranged clock of the charging station, and the corresponding contact of each accumulator battery with a shape that fits into this lock, for example with a mushroom-shaped cross-section. In this way, a simple safeguard against the insertion or the electrical connection of fillers or primary elements at this loading area is prevented. At the same time, by attaching the lock to one contact of the charging station, it is ensured that the accumulator battery can only be inserted into the electrical connection of the charging station in the correct position, ie with the correct polarity. A related backup will also be made at every charging point of the charging device.

The invention finally creates a very versatile power source that can be combined for a wide variety of operating voltages. It is therefore of particular advantage if, within the scope of the invention, the FÜ11 eafel pieces and the accumulator batteries of different cell
