Gravity battery discharge model and equivalent circuit design

Gravity batteries, as an innovativealternative to existing energy storage systems, have the potential to offer a more efficient and sustainable solution.In this study, an equivalent circuitmodel has been created to analyze the discharge process of gravity batteries.First, the mechanical and electrical properties of the system wereexamined, and it was associated with an RL circuit, leading to the derivation of its mathematical model.Then, the identified model was simulated in theSimulink environment, and the dynamic behavior of the system was analyzed.Additionally, the system's motion equation was derived, and theminimum operating height was determined to evaluate the critical parameters in the energy conversion process.The proposed equivalent circuit model offers apractical method for examining the discharge process of gravity batteries.
