The invention provides a gravity energy storage system which specifically comprises a mass block, a transmission assembly and a motor, and when gravitational potential energy needs to be stored, the motor acts to lift the mass block through the transmission assembly so as to store the gravitational potential energy; when electric power is needed, the mass block falls to release gravitational potential energy, the falling mass block pulls the motor through the transmission assembly to generate electric energy, the height of the mass block and the gravitational energy storage height are in a preset height ratio, and the preset height ratio ranges from 0.4 to 0.6, so that more gravitational potential energy can be stored/released as much as possible under the limited gravitational energy storage height. Therefore, the energy density of the gravity energy storage system is obviously improved.
本申请提供一种重力储能系统,其具体包括质量块、传动组件以及电机,在需要存储重力势能时,电机做功通过传动组件抬升质量块,以存储重力势能;在需要电力时,质量块下坠释放重力势能,下坠的质量块通过传动组件拉动电机产生电能,其中,质量块的高度与重力储能高度成预设高度配比,预设高度配比在0.4至0.6之间,这样可以在有限的重力储能高度下,尽量存储/释放更多的重力势能,从而显著提升重力储能系统的能量密度。
