Power storage module of energy storage system and energy storage system

Abstract

The invention discloses a power storage module of an energy storage system and an energy storage system. The power storage module comprises an independent shell and a battery pack; the independent shell is of a sealed structure and comprises a shell body and a door body; the shell body is provided with a containing cavity, and the door body is used for opening and closing a cavity opening of the containing cavity; and the battery pack is mounted in the containing cavity. According to the power storage module of the energy storage system, a sealing structure is formed through the independent shell, and the battery pack is installed in the independent shell, so that the containing cavity in the independent shell is completely isolated from the outside, and the situation that the energy storage system cannot work normally due to false fire alarms caused by wind and sand entering the containing cavity is avoided; meanwhile, the situation that thermal runaway of a single power storage module induces thermal runaway of other power storage modules of the energy storage system can be avoided, large fire disasters caused by fire chain reactions are avoided, and fire disaster losses and fire extinguishing difficulty are reduced.

Description

technical field [0001] The present invention relates to the technical field of energy storage, and more specifically, to an electric storage module of an energy storage system and an energy storage system. Background technique [0002] In the related art, battery racks equipped with battery clusters are arranged in the container to form an energy storage system. If the battery cluster on one of the battery racks is thermally out of control, the battery clusters in the entire container will be scrapped. Moreover, the air circulation space is formed between the container and the outside world, and it is inevitable that wind and sand will enter the container, which will trigger the smoke detector, cause a false fire alarm, cause the energy storage system to fail to work normally, and even cause the energy storage system to automatically extinguish the fire and cause damage to the battery cluster. Contents of the invention [0003] The present invention aims to solve at least ...
