Modular energy storage system

The invention relates to the technical field of energy storage, in particular to a modular energy storage system. The system is composed of the energy storage device, the battery modules, the power supply module, the power consumption module and the control center, the number of the battery modules can be selectively set according to user requirements, then the working performance data of the battery modules and the electric energy supply and demand performance of the system are collected, the optimal battery module use scheme is obtained, and intelligent and efficient energy storage and energy consumption are achieved. The energy storage equipment is provided with the cooling assembly, and on one hand, air supply and cooling above the battery module are achieved through lifting of the piston plate. On the other hand, the fan blades rotate through rotation of the threaded sleeve, and air supply and cooling below the battery module are achieved. And through synchronous cooling and heat dissipation of the batte
