Problems solved by technology

After the thermal runaway of the battery, a large amount of organic substances are released, including flammable and toxic gases such as CO and H2. The working environment of the battery energy storage system is relatively airtight, and the flammable gases cannot be released and there is a risk of explosion if they gather in large quantities.

Description

technical field [0001] The invention relates to the field of energy storage systems, in particular to a modular energy storage system. Background technique [0002] With the development of society, energy storage power stations are an important part of electricity use. In recent years, the energy storage industry has developed rapidly, and the large-scale commissioning of grid-side projects has brought changes and opportunities in the industry. The scale of electrochemical energy storage commissioning is increasing, and the energy storage system is bulky and inconvenient for transportation and assembly. Moreover, batteries are prone to thermal runaway combustion due to their high energy density and flammable and explosive material systems. Battery fire is a process of heat accumulation. After the thermal runaway of the battery, a large amount of organic substances are released, including flammable and toxic gases such as CO and H2. The working environment of the battery en...
