Problems solved by technology

[0004] At present, the energy storage battery thermal management system mainly adopts air cooling, liquid cooling, phase change material cooling or several methods of coupling. These methods have disadvantages such as complex system structure and high system energy consumption. However, the relatively mature liquid cooling system is not It is suitable for large-scale power station battery energy storage systems. This is mainly because the battery energy storage system accumulates a large number of batteries in a certain space, and the unified management of temperature control and fire protection cannot be achieved uniformly, which will cause high energy consumption and high cost of the system. no problem

Abstract

The invention discloses a centralized energy storage equipment thermal management system and a working method thereof, and belongs to the technical field of energy storage. A main controller is directly connected with a water pump and temperature measuring points of each stage in an energy storage system, centralized management and control are conducted on heat management of distributed energy storage units, a heat management mechanism of a single energy storage unit is omitted, energy consumption of the energy storage system is effectively reduced, and the design, installation and maintenancecost of the system is reduced. Through the real-time communication state information of each monitoring point in each stage of the energy storage system, the environment temperature of each stage inthe energy storage system is accurately controlled; and forced separation and cooling can be carried out when a certain energy storage unit is in a sudden thermal runaway state, so that the occurrenceprobability of sudden safety problems is reduced, huge economic losses caused by thermal runaway of the energy storage system are reduced, and the safety and stability of the energy storage system are improved.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a thermal management system of a centralized energy storage device and a working method thereof. Background technique [0002] When analyzing the energy storage process, some objects or space ranges drawn in order to determine the research object are called energy storage systems. It includes energy and material input and output, energy conversion and storage equipment. An energy storage system often involves multiple energies, multiple devices, multiple substances, and multiple processes. It is a complex energy system that changes with time, and requires multiple indicators to describe its performance. Commonly used evaluation indicators include energy storage density, energy storage power, energy storage efficiency, energy storage price, and environmental impact. [0003] Electrochemical energy storage refers to various secondary battery energy storage. It...
