In order to meet the future development trend of “ low-carbonand “ greenenergy ，theexperimental equipment was built to investigate the gravitational energy storage and discharge and the relatedfactors affecting its efficiency.The experimental results show that the efficiency of gravitational energy storageand discharge has the best peak value for a certain weight mass and supply voltage.The experimental setup issimple in structure, easy to build, and suitable for conducting research on gravitational energy storage anddischarge.
