Cabinet type container for energy storage and energy storage system

Abstract

The invention discloses a cabinet type container for energy storage and an energy storage system. The cabinet type container comprises a cabinet body in the shape of a rectangular box body, the two side faces of the cabinet body in the width direction are of an open structure, a plurality of vertical plates are arranged in the cabinet body in parallel, and all the vertical plates are evenly arranged at intervals in the width direction of the cabinet body. A plurality of transverse plates are uniformly arranged between adjacent vertical plates in parallel at intervals, battery modules are oppositely arranged on each transverse plate at intervals, a rectangular air duct notch is formed in the center of the top surface of the cabinet body, and the air duct notch downwards cuts all the vertical plates and the transverse plates between the two vertical plates located on the outermost side from the top surface of the cabinet body. A plurality of openable cabinet doors are arranged on the two side faces of the cabinet body in the width direction. According to the energy storage system, a traditional maintenance passage is omitted, doors are opened on the two sides, the integral battery rack is adopted, installation and maintenance are convenient and fast, meanwhile, the energy density can be improved, installation of the battery modules on the battery rack is improved, and the structural stability of the energy storage system is improved.

Description

Technical field [0001] The present invention relates to the field of lithium battery accommodation, and more particularly to an energy storage cabinet container and an energy storage system. Background technique [0002] With the continuous development of lithium electrical technology, and the strong support of lithium batteries and new energy technologies in the world, large lithium battery energy storage devices have been more and more R & D and application. At present, there are many container structural energy storage devices, which is to install battery modules and battery management systems in containers, and install numerous auxiliary systems such as fire extinguishing systems, refrigeration systems, ventilation systems, etc. [0003] Traditional energy storage container structure figure 1 As shown, there is two row of battery holders in the container and there is a aisle between the two-row battery holder. Due to the lanes in the container, it is not conducive to the incr...

AI Technical Summary

Problems solved by technology

Due to the aisle in the container, it is not conducive to the improvement of the volume energy density of the energy storage device, and it is difficult to assemble the battery module in the aisle, which also causes great difficulties for maintenance.

Moreover, the battery rack is independent from the container, and the battery rack needs to be installed twice. Due to the heavy weight of the battery rack itself and the limitation of the internal space of the container, the installation is very difficult, which seriously affects the production cycle

In addition, the fixing of the battery module on the battery rack is only limited in the horizontal direction, and there is no limit in the vertical direction. The fixing strength of the battery module is low. After earthquake or transportation vibration, it will have a certain impact on the system stability.
