Description

I

The invention of converting to converting technology and can be used in devices for forming, training, and testing batteries.

Known capable of forming, training and testing of batteries, by cycling their charge-reer dia. Currents 1.

. For the purpose of cyclic cycling processes, it is desirable to take the duration of wage and discharge cycles approximately equal, since the effect of Yip and% p on cycling within the applicable limits due to the low sensitivity of alkaline batteries to charge and discharge regimes does not have a significant influenced the number of "cycles obtained by test 2J.

 At the same time, the frequency of cycles does not exceed one cycle of charge-discharge in several hours.

High-efficiency systems are known for batteries for batteries, containing a reversible rectifier, to the output terminals of which is connected a common anode-cathode points battery, sectioned in the form of a symmetrical quadruple M-Shift, to a common anodic and cathode point of which the node has current of {3 |.

Due to the work of the reverse level of the body on the difference in voltage of the opposite-connected terminals of the battery, it is calculated on a lower power as a current source, rather than energy, providing "non-pumping of energy from the discharged to the charged sections. With

Thereby, the difference between the charge and discharge energies (energy, and losses) is compensated by an additional DC source.

A disadvantage of the lime system of charge. The relatively large installed capacity of the equipment and the reduced efficiency due to the partial compensations in the discharged sections of the currents of the reversing power supply and the DC source are relatively large. The purpose of the invention is to reduce the setting of the Equipment's Density and higher efficiency.

This goal is achieved by introducing two key elements into the system, connecting them with back-to-back D1P sections of the battery pack into four (the humeral bridge and connecting the accumulation point of the satellite to the iio and io and rum output clamp (source; direct current.

On fng. 1 shows the lrinnigal and the diagram of the proposed charging system, the circuit contains a reversible rectifier I, battery cell sections 2, 3, key elements 4, 5, and a source of constant current 6.

FIG. 2 a, b show current diagrams in the charge system;

Two circuits are connected to the output terminals of the reversing rectifier I, with:) consisting of counter-connected sections of the battery 2, 3 and of the connected-connected key elements 4, 5 in a free diagonal of which direct current source 6.

When the reversing rectifier 1 is turned on, for example, in the forward direction (see Fig. 1), the section of the battery 2 and the discharge of section 3 are charged by the same current of the reversing rectifier 1, the installed power of which is determined by the product of this current and the difference in nanowires of counter-sequentially connected sections of a battery, 3.

Since the discharge capacity of the sections of the battery 2, 3 is always less than their charge capacity due to joule and electrochemical losses and can reach up to 0.6 of the charge capacity, fjanpHMep, when testing or molding 2j, and being equal to the charge capacities and the discharge cycles for the corresponding magnitude must be greater and the charge current.

To do this, during the charge cycle of the section of the battery 2, the key element 4 is turned on and under the difference between the direct current source 6 and section 2 an additional charge current flows through this section.

When switching the reversing rectifier 1 and changing the direction of its current flow, the section of the battery 2 starts to discharge, and section 3 is charged. In accordance with the switching of the valves of the reversing rectifier 1, the switching of the key elements 4, 5 is performed - the key element 4 is opened and the key element 5 is closed. A second circuit of charge current flow formed by a series-connected DC source 6 is formed, a section of the battery 3 and key element 5.

Consequently, in both clock cycles of the system, the current of the charged section of the battery is determined by the sum of the currents of the reversing rectifier 1 and the source of direct current 6, and the current of the discharged section is only the current of the pkp-rsinigl pyrn mngol (see Fig. 2 l, b).

Due to the fact that the current is recursive), BbiiipHMHje.THs and with (), the response is set to 5pio and the .ieinias is set, its power is b) and is determined by TOL1. Co: 1r. cycling battery sections.

Due to the fact that the source of constant voltage alternately operates at half the voltage of the cycling battery, the installed power supply of the source equipment is approximately halved.

Due to the elimination of the mutual compensation and TOKO.CH reversible rectifier of the source and the source of direct current in the discharged sec, and x battery, the current load of all circuits of the charging system is reduced.

i and electrical losses, and accordingly increases the KPD.

The indicated advantages of the proposed charging system, as well as the need to expand the battery of the battery not by 4, but into two sections, with an excess of J compensate for the installation of two additional key elements.

In the simplest case, contact devices may act as follow-ups.

 (relays, contactors, reversors, circuit breakers, etc., or contactless semiconductor devices controlled from a common control unit of the system}.
