Description

The utility model relates to devices for effective battery charge (UEZA) and can be used in the electrical industry.

Known charger containing a rectifier, reference capacitance, transformer, load connection terminals (AC USSR No. 1001311, class. H02J 7/10, 1983).

The specified charger does not provide an effective battery charge.

The closest set of essential features and the achieved result is a charger containing a rectifier, a reference capacitance, a high-frequency transformer, a control system, a shunt, load connection terminals (RF No. 97880 U1, class H02J 7/10, 2010).

The specified charger does not provide an effective battery charge.

The technical result of the utility model is to increase the battery charge efficiency by reducing the internal resistance of the battery in terms of the polarization activation component.

The specified technical result is achieved in that the UEZA contains a rectifier, a reference capacitance, a high-frequency transformer, a control system, a measuring shunt, positive and negative terminals for connecting the battery, while the device further includes a modulation level controller, a pulse generator, a current chopper, a control system for microcontroller based.

The charge device, made in this way, allows to increase the battery charge efficiency by reducing the internal resistance in terms of polarization and activation components.

It is advisable that the load of the pulse generator is the primary winding of the high-frequency transformer and the capacitor connected in series, and the secondary winding of the transformer is connected in series with the positive terminal for connecting the battery.

This inclusion of a high-frequency transformer can significantly increase the efficiency of the charge due to the direct supply of the charging voltage to the battery.

It is advisable that the modulation level regulator be a half-bridge of key elements, and a pulse generator should be connected to the output of the regulator through a bC filter.

It is advisable that the circuit breaker was installed in series between the shunt and the negative terminal for connecting the battery.

In FIG. 1 shows the functional diagram of the UEZA. The circuit includes a rectifier B1, a reference capacitor C1, a regulator for modulating the RUM, a pulse generator GI, a high-frequency transformer T1, a measuring shunt Z1, a current breaker PT, a positive negative terminal OUT, a rechargeable battery.

The mains voltage (220 V. 50 Hz.) Supplied to the input of the rectifier B1 is converted to direct current with a voltage corresponding to the nominal battery (Urab).

From the output of the rectifier, the voltage is supplied to the RUM, SU and T1.

RUM, through control from the SU, provides power to the GI in the range from 0 to Urab.

GI provides pumping the transformer with pulses of duration and frequency, which sets the SU.

The positive voltage potential coming from B1, modulated by the transformer T1, goes directly to the terminal (+) of the battery.

The negative voltage potential through the current meter 21 and the current breaker PT is supplied to the terminal (-) of the battery.

SU sets;

1. PWM (pulse width modulation) for the RUM terminals GV1, GV2.

2. The formation of frequency and duration for the GI conclusions GV3, GV4.

3. Duration control PT output GV5.

4. Control the amount of battery charge current ADJ pin.

All of the above control signals are generated based on the measured values;

a) the measured current voltage of the battery,

b) the current value of the battery charge / discharge current,

c) the first derivative of the charging current with respect to time,

g) the first derivative of the charging voltage with respect to time,

d) battery temperature.
