DEVICE FOR EXPRESS DIAGNOSTICS OF ELECTROCHEMICAL BATTERIES

Leader: supervisor of Autonomous Energy Laboratory,

Chief Scientist, Doctor of Technical Sciences, Professor Bezruchko K. V.

In the laboratory of autonomous energy of Kharkiv Aviation Institute are developed method and a device that allow a full diagnosis result of electrochemical batteries without interfering with their work in a short time.

Device based on pulse diagnostic method of electrochemical batteries. The essence of this method (developed in Kharkiv Aviation Institute) consists on a special impact the battery sequence current pulse, measurement and analysis of the response voltage and determining the basic parameters of the battery by means of special mathematical models.

The device allows you without a charge-discharge cycles, without interfering with the logic of the electrochemical battery life and using some test parameters to determine its basic parameters (such as the charging performance (Fig. 2), the discharge characteristic (Fig. 3), the current-voltage characteristic , the actual capacity, the

charged, the internal resistance, and others.) for a limited time.

DEVICE FOR RECOVERY OF

ELECTROCHEMICAL BATTERY

Leader: supervisor of Autonomous Energy Laboratory, Chief Scientist, Doctor of Technical Sciences, Professor Bezruchko K. V.

In the laboratory of autonomous energy of Kharkiv Aviation Institute are developed several

methods for the recovery of electrochemical batteries, which allow to fend off all the main degradation processes in electrochemical batteries.

The proposed device (Fig. 1) is based on two methods of recovery of batteries: battery deep discharge followed pulsed charge.

This device allows to restore degraded electrochemical batteries and secondary used them. Recovery electrochemical batteries will reduce costs for the purchase of new batteries and disposal costs of harmful components included in the composition of the electrochemical battery.

The proposed device allows not only rehabilitation activities, but also control and training cycles of electrochemical batteries, which significantly increase the battery life of some electrochemical systems and improve their working conditions.

The proposed device allows to restore the electrochemical batteries of different electrochemical systems.

The results of recovery batteries (for example NiCd with capacity 28 A∙h) shown in Fig. 2.
