Simplified Mathematical Model

This paper proposes a model for metal hydride elements which are used as hydrogen accumulators for different types of thermal powered systems. The quasi-stationary method has been used to obtain a simplified mathematical model. Calculations to predict the dynamic response of a thermal energy engine have been made.

Nowadays, batteries used in many areas such as RES have an important place in energy storage. Because of the unstable and intermittent structure of RES, battery energy storage technology is becoming important. There are many different types of batteries in the market, such as lead-acid, nickel-metal hydride, and lithium-ion. It is very important that these batteries are well recognized and controlled accordingly to extend their cycle life. In this study, necessary parameter values were obtained by conducting lead acid, nickel-metal hydride and lithium-ion charge-discharge experiments by using climatic chamber in the laboratory environment. A single model was created using curve fitting for three different battery types. In addition the electrical model of the batteries, the temperature model was also combined to conduct state analyzes at different operating temperatures of the batteries and a mathematical model was derived. The obtained mathematical model MATLAB/M-File program was used to compare with the experimental results. In this paper, electrical and thermal mathematical equations for different types of batteries are compared with experimental and model results and the accuracy ratios are given.
