This invention relates to electrical industry and can be used in the development of si. The system of charging and forming batteries of various types and purposes.

A device for cycling a battery containing a charge source, a charge-discharge current sensor and a stabilization unit l., 0 is known.

However, this device does not allow a change in the ratio of the durations of the pulses of the charging and discharge currents of various shapes.

The closest in technical essence is an asymmetric current device for charging a battery, which contains a stable frequency generator, a frequency driver with a variable sharing factor, a stabilization unit, a Walsh function synthesizer, whose outputs are connected to the input through the weight setting blocks. power amplifier .and, and the output of the power amplifier through the current sensor is connected to the battery (2).

The disadvantage of this device is that, if it is necessary to change the duration of the charging and discharging current pulses, some reorganization of the Walsh functions synthesizer is necessary.

The purpose of the invention is to expand the functionality of the device.

This goal is achieved by the fact that four matching schemes are introduced into the device, the OR scheme and the second and third variable frequency drivers. the division factor, whose inputs through the corresponding coincidence circuits are connected to the output of the first frequency driver, and the outputs through the corresponding coincidence circuits and. the OR circuit is connected to the input of the Walsh function synthesizer, the second inputs of the coincidence circuit are connected to the corresponding outputs of the Walsh function synthesizer. The drawing shows a functional diagram of the device. The device includes a stable frequency generator 1, drivers 2, 3 and frequencies with a variable division factor, a matching circuit, a circuit OR 9 a Walsh function synthesizer 10, blocks 11 and 12 for setting weights, a power amplifier 13, a current sensor I and a stabilization unit 15. The device works as follows. The frequency pulses f from the stable frequency generator 1 are fed to a frequency generator 2 with a variable division factor q. Using schemes 5, 7, and 6, 8, match the frequency formers 3 and 4 with variable division factors q. -CH are alternately connected by control signals to the output of the frequency generator 2 frequencies and the corresponding input of the circuit OR 9. From the output of the circuit OR-9, the pulses go to the input of the synthesizer 10 Walsh functions, and their frequency is equal to time of formation of a charge current pulse and Chz in ° time of the formation of a pulse of discharge current. The time of formation of the pulses of the charge and discharge currents is determined by the pulse frequency received at the input of the Walsh function synthesizer. Thus, by changing the division coefficients Ч CH. H, we are able to adjust the duration, the ratio of the durations and the frequency of the pulse of charge current and discharge. The signals from the outputs of the synthesizer 10 Walsh functions are fed to the inputs of the blocks 1 1 and 12 sets the weights. The formation of charge and discharge current pulses occurs separately, which makes it possible to regulate their parameters separately. Pulses with an output of blocks 11 and 12 of the task of weighting factors are fed to the input of the amplifier 13 power. The output voltage of the power amplifier 13 through the current sensor 1i is supplied to the battery 16. As the battery 16 charges and the counter-EMF increases, the stabilization of the charging current is carried out by the stabilization unit 15, the input of which is received from the current And This ensures that the current pulse shape of the charge current corresponds to the shape of the pulse coming from the weight setting unit 11, and the current pulse shape to the shape of the pulse coming from the weight setting unit 12. If the shape of a pulse of discharge current corresponds to the shape of a pulse of charge current, then it is advisable to build a device with one unit for setting weighting coefficients. The use of the proposed device will allow to obtain the required frequency, duration and ratio of the durations of the charging current of a darazr. As a result, the functional capabilities of the device will be expanded, which will increase the scope of its application and eliminate the need to develop a number of devices, the range of operating parameters of which is close to the range of operating parameters of the proposed device.
