High-safety module partition type energy storage system and working method thereof

Abstract

The invention discloses a high-safety module partition type energy storage system and a working method thereof, and belongs to the technical field of energy storage batteries. The energy storage system comprises a battery module, a temperature sensor, a battery module cooling system, a fire monitoring device, a fire extinguishing system, an isolation bin and a smoke exhaust system, wherein each battery module comprises a plurality of single batteries, and each battery module is independently arranged in the closed isolation bin; and the temperature sensor, the battery module cooling system, the fire monitoring device and the fire extinguishing system are arranged in the isolation bin, and the smoke exhaust system is connected with the isolation bin. According to the invention, it can be ensured that the battery module in the energy storage system works at a proper temperature, meanwhile, the fire-fighting emergency capability when the battery in the energy storage system has a local problem is greatly improved, the occurrence of a spreading accident caused by the local safety problem of the energy storage system is completely eradicated, and the application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and in particular relates to a high-safety modular partition type energy storage system and a working method thereof. Background technique [0002] With the vigorous development of renewable energy, a large-scale energy storage system is needed to support the relief of peak-shaving and frequency-regulating pressure on the power grid and improve the ability to accommodate new energy. At present, the electrochemical energy storage system is one of the fastest-growing methods among all energy storage methods. With the large-scale application of electrochemical energy storage systems, its safety issues cannot be ignored. Because the battery contains a large amount of organic electrolyte, the battery energy storage system has certain safety risks. When the temperature uniformity between the batteries is poor or the battery is overcharged and overdischarged, some parts of the battery m...

AI Technical Summary

Problems solved by technology

Because the battery contains a large amount of organic electrolyte, the battery energy storage system has certain safety risks. When the temperature uniformity between the batteries is poor or the battery is overcharged and overdischarged, some parts of the battery may smoke or catch fire. If it is not handled properly, it may cause the entire energy storage power station to catch fire or even explode, causing huge personal casualties and property losses

[0003] At present, the safety protection of the battery energy storage system is mainly for the protection of the entire energy storage container. Usually, fire sprinklers are installed directly in the energy storage container. , this will not only cause large losses, but also easily generate a large amount of toxic and harmful combustible gases in the entire container to cause secondary hazards. Extensive fire management cannot support the further large-scale application of energy storage systems
