Problems solved by technology

[0007] The purpose of the present invention is to provide an energy storage system with high energy density and easy transportation, so as to achieve the effect of low cost and low investment, and solve the problem that the current domestic energy storage containers cannot meet the requirements of foreign storage containers in terms of transportation and energy density. The weight of each warehouse is controlled within the maximum weight requirements for sea transportation, and there is no need to install battery modules on site; there is no need to set up an air conditioner and fire control center in the battery warehouse, and all control systems are under control. The integration in the compartment can not only increase the capacity of the battery compartment, but also facilitate the operation and management of maintenance personnel; in addition, multiple battery compartments support end-to-end connection to form an integration, which is convenient for capacity expansion and reduces the floor space

Abstract

The invention relates to a high-energy-density and convenient-to-transport energy storage system, which comprises at least one battery bin and a control bin. The battery bin and the control bin are in a container type and are detachably connected, a plurality of battery cabinets, confluence cabinets and fire-fighting modules are arranged in the battery bin, the fire-fighting modules are connected to a cooling water pipe and a fire-fighting pipe, the outer wall of the battery bin is provided with a first fire-fighting fast interface and a first circuit fast interface, the control bin is internally provided with an energy storage converter, a control cabinet, a fire-fighting master control center and a liquid-cooled air conditioner, and the outer wall of the control bin is provided with a second fire-fighting fast interface and a second circuit fast interface. Compared with the prior art, the weight of each bin is controlled within the maximum weight requirement of sea transportation; all control systems are integrated in the control bin, so that the capacity of the battery bin can be increased, and maintenance personnel can operate and manage conveniently; expansion is facilitated, and the occupied area is reduced.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to an energy storage system with high energy density and convenient transportation. Background technique [0002] With the world's attention and support for carbon neutrality, more and more new energy projects such as wind energy and photovoltaics are connected to the grid. However, these new energy sources cause large fluctuations to the grid, and sometimes the grid cannot absorb them, resulting in abandonment of wind Light, the burden on the power grid system is increasing day by day. [0003] The large-scale energy storage system is a means to effectively solve the problem of curtailment of wind and light. Store energy in the energy storage system when the grid cannot accommodate it, and supplement the energy in the energy storage system to the grid when the grid can absorb it, alleviating the impact of new energy such as wind energy and photovoltaics on the grid. , impr...
