• Supply reliability of modern energy systems,
• Ensuring system stability,
• More efficient use of energy resources,
• Reducing the transmission distribution problem,
• Minimization of costs.

Why;
Research and examination of energy storage units, especially for off-grid applications, is of great importance.
Alternative energy sources are highly dependent on the conditions of nature.
Energy storage units are of great importance in successfully meeting the load’s energy need in any case.
The excess energy produced from alternative sources is transferred to different types of energy storage units, and this stored energy is used to meet the load demand in cases where the main sources are not available or insufficient.
One of the most important arguments of Energy Storage Systems is battery systems.
Battery systems are one of the oldest applied methods of storing electrical energy in chemical form.
Battery systems are divided into non-rechargeable primary batteries and rechargeable secondary batteries. A battery system is composed of one or more electrochemical cells.
In the discharge state, electrochemical reactions at the electrodes generate a flow of electrons in an external circuit. In the charging state, electrochemical reactions occur in the opposite direction by applying a voltage to the electrodes.
