Definitions

• Charger of electric accumulators The sector of the technique of this patent is that of the chargers for electric accumulators, both batteries and batteries, of the type of which are called rechargeable, as of the so-called non-rechargeable ones, which by means of this type of charger accept and maintain the recharge.
• ES P9101267 per circuit and apparatus for recharging accumulators, batteries or electric batteries and other specific use, of the same applicants as this one, is constituted by a circuit that in direct current provides for consumption in a part of the circuit and a load terminal .
• US A3391321 per battery charger (batteries) in series holders, which is formed by a battery case attached to a series circuit; It has a resistor and a diode on a branch of the circuit, a warning light and a switch.
• the present invention aims at a charger of electric accumulators that produces an input current flow of greater voltage than the nominal output of the corresponding accumulator, being provided with a circuit that determines a charge regulation, according to the specific use for batteries, and for batteries of any kind.
• a traditional battery charger carries out charging by providing a current flow of a stable voltage and decreasing amperage depending on the charge level of said battery.
• the charging system proposed by this patent carries out the charging by means of a contribution of a current flow whose voltage is higher than that of the battery to be charged, and the. amperage.
• This charger consists of a circuit in which the output voltage of the transformer is greater than the voltage of the battery to be charged, for example from 5 to 10 volts more than the voltage of the battery to be charged, and from the voltage of the battery, the increase in this voltage determines a significant reduction in charging time, being optimal - this increase from 10 volts, producing a constant charge, derived from the voltage drop that occurs through interleaving well before the transformer or after this, a circuit, such as one or more reactances, a transformer, a set of diodes, a resistor, whose consumption will be in accordance and in relation to the voltage and amperage of the transformer.
• This system also performs its function because it acts differently from the traditional loaders known today in the following cause effect.
• a conventional charger that connects to a more or less discharged battery and marks a current input of 10 A. If another charger is connected to the same battery, of the same characteristics, the latter will not add a current input of 10 A As the first one marked, but the two will significantly lower the current input to the battery, when the first one is divided between the two with a minimum increase of the initial 10 A.
• both the current input would be 20 A., which is the sum of the 10 A. + 10 A. provided by each charger of the same characteristics that we were connecting to the battery, as if we connected to a battery a charger 7 A. where two of 10 A. had already been connected, the sum would be 27 A., with an oscillation of between ⁇ 1 and 3 A for losses not inherent in the charging system.
• the input current is cut by means of a relay, kit, clock or other technically available means.
• the principle on which this charging system is based is derived from the possibility of producing a load input that linearly provides during the charging process all the energy that is capable of absorbing the accumulator, according to the corresponding circuit. This determines that the electricity supply does not decrease according to the state of charge, and therefore it is absolutely effective, and obtains the total charge of the accumulators.
• the battery charging system is carried out in the same way and under the same principle; the voltage drop due to voltage difference.
• the difference between the two is that for the batteries, the diverter or compensator cutting system of the charging current, acts by means of rectifiers and diodes. In these circuits, when the battery has been charged, the current is diverted by the rectifiers and diodes, not overloading the batteries to be charged.
• Figure 1 shows an example of a complete circuit.
• Figure 2 shows a pole of said circuit according to a possible embodiment.
• Figure 3 shows a pole of said circuit in a third embodiment.
• Figure 4 shows a second example of a complete circuit.
• the voltage input to the circuit with 2 a reactance arranged before a transformer 3, the diverting or compensating circuit of the load current is formed by at least one diode bridge or rectifier that is indicated 4, preceded by at least one diode 7, and without being inherent in the system but only a control means, an ammeter 5 is arranged before the load output terminals indicated by 6.
• the rectifier one or more in series, indicated by 10.
• Figure 2 has the difference between the embodiment of Figure 1 that the reactance is in the transformed current circuit and is indicated by 2.1; It has the advantage that the reactance of a low voltage current needs less thickness of turns and therefore is lighter.
• Figure 3 has as characteristic against the previous two that in the same type of circuit, the reactance has been replaced by a set of series diodes that are indicated by 8.
• This described circuit carries out the charging, preferably of small accumulators. Its principle is based on the fact that the current that has output from terminals 6 is rejected by the accumulator when it is full, and under these conditions it is absorbed by the compensating circuit; on the one hand by the reactance, by the diode bridge, and by the diodes in series in the case of figure 3, determining an energy absorption that does not reach the last part of the circuit if the accumulator is full.
• Figure 4 shows a circuit essentially similar to the previous one, whose application is intended for charging more powerful accumulators, allocating instead a circuit for the absorption of energy that is no longer provided to the accumulator, a circuit cut by state of charge .
• the voltage input coming from 1.1 is represented: either from the power grid, or from an alternator or dynamo. With 2 the reactance that can occupy the position 2.1 and possibly be formed by a series set of diodes as indicated by 8 is indicated.
• the cutting circuit 9 is located in the rectified current circuit, thereby detecting the voltage of the battery, in whose predetermined limit it cuts the power supply.
