CONTROLLING THE ELECTROCHEMICAL ENERGY STORAGE CHARGING PROCESS

Purpose. Substantiation of the impulse galvanostatic method of monitoring and controlling the process of charging an electrochemical energy storage device based on a lead-acid electrochemical system, and developing an algorithm for its implementation. Methodology. The investigations using the pulse method of automated monitoring the energy storage device current state, in which the values of the informative parameters are determined from the storage response signal to the current test pulse, and the charging process is controlled according to the developed algorithm taking into account the current state of the storage device, were carried out. Findings. The developed method of monitoring and controlling the process of storage charging and the algorithm for its implementation allow to reduce the storage charging time in comparison with the galvano-potentiostatic method. Information about the dynamics of the charging process is displayed on the monitor screen, which allows visually monitoring the storage charging process and record the completion time. Originality. The authors substantiate the impulse galvanostatic method of monitoring and controlling an electrochemical energy storage device charging process, in which the parameters of the electrochemical process in the storage reflecting it’ s current state are used as informative parameters for the charging process . Practical value. An algorithm for the implementation of a method for monitoring and controlling the process of an electrochemical energy storage device charging, which can be used to provide an optimal charging regime for energy storage devices in autonomous photovoltaic power supply systems has been developed.
