Detachable composite cooling device for energy storage system package and its cooling method {DETACHABLE COMPLEX COOLING APPARATUS AND METHOD FOR ENERGY STORAGE SYSTEM PACKAGE}

The present invention relates to a detachable composite cooling device for an energy storage system package and a cooling method thereof, and more specifically, the electric energy generated by solar power generation for an average of about 3.6 hours a day by sunlight is transmitted through a transmission line of the Korea Electric Power Corporation. At the same time, it is stored in the energy storage system (ESS), and the energy storage system can generate heat and increase temperature due to charging and discharging, so it has energy with a constant temperature and humidity function as well as a cooling function that reduces the temperature of the energy storage system. The present invention relates to a removable composite cooling device for a storage system package and a cooling method therefor.

In the power environment, the existing centralized transmission/distribution system causes problems in energy management efficiency due to inconsistency in power supply and demand, and quality of new and renewable energy (solar power, wind power, etc.) is caused by irregular electricity production. It is degrading the stability and reliability of the power grid.

In addition, large-scale power outages are frequently occurring due to the rapid demand for electricity in summer and winter. As a solution to these problems, the need for an energy storage system (ESS) is emerging.

The energy storage system can be an alternative to improve the stability and reliability of the power grid, solve the irregular output characteristics according to the weather of new and renewable energy, secure efficient power, secure high quality power, and achieve the goal of stable power supply. have.

The energy storage system (ESS) required in the power system is largely classified into long-term ESS and short-term ESS according to various outputs and storage times.

An energy storage system (ESS) is a system that stores excess power generated in a power plant in a power grid, and then increases power efficiency by supplying power when the power is most needed or temporarily lacking power.

That is, it refers to a technology that stores large-scale power in various ways, such as large-sized secondary cells such as lithium-ion batteries, or using fly wheels and compressed air (CAES).

The energy storage system (ESS) is composed of a battery that stores electricity and a related device that efficiently manages it.

The long-term ESS uses active power at the base load and is used for energy management to increase the efficient operation and stability of the power system. Lithium ion batteries, Redox Flow Battery (RFB), NaS and Compressed Air Energy Storage (CAES) systems.

The short-term ESS is used to improve the power quality to prevent instantaneous power failure of the smart grid and to mitigate output fluctuations of renewable energy sources, and includes ultra-high capacity capacitors and FESS (Flywheel Energy Storage System).

In the future, the medium-sized ESS market is expected to increase rapidly due to the expansion of renewable energy and the expansion of the electric vehicle market. It is expected to be formed into the market for electric vehicle power supply, renewable energy, and arbitrage trading. By capacity, battery industries such as lithium-ion batteries, NaS, RFB of 50 MW or less are categorized, and CAES and pumped power generation of 50 MW or more. It is expected to form a market with large power generation industries such as systems.

The secondary battery market using a lithium ion battery (LIB, Lithium Ion Battery) has attracted great attention not only in the field of energy storage systems (ESS) but also in the field of electric vehicles (EV).

However, in the conventional energy storage system (ESS), when the battery receives a physical shock, the structure of the battery cell may change, and the internal separator of the battery may not function properly, or the battery may generate heat and ignite (heat runaway, about 170℃~ 70℃) There are problems in safety accidents, such as an explosion leading to a fire.

Conventionally, in order to solve the heat generation problem of the battery of the energy storage system (ESS), a ceramic coating is applied on both sides of the separator, and a binder having high heat resistance is used to withstand high temperatures at 150 to 200°C, but manufacturing cost increases. There is a problem, it is technically unable to completely solve the existing fire problem.

On the other hand, the Peltier effect (Peltier effect, thermoelectric effect) was discovered in 1834 and theoretically established in the early 1900s, it is also called an electric refrigeration system.

The Peltier effect is a phenomenon in which a temperature difference persists at both ends of several layers of a conductive material when a current is passed, and when the high-temperature portion of the opposite side requiring low-temperature cooling is forcedly cooled, heat of the low-temperature portion is transferred to the high temperature. When one side is cooled by the control back effect, the other side becomes hot. Cooling the hot side well improves efficiency, and if overheated, the efficiency decreases, and the Peltier element may be destroyed only after a sudden supply, or a low temperature portion and a high temperature portion may be reversed.

Conventionally, although there is a Peltier element cooling system that uses a heat sink of a Peltier element and a heat dissipation fan in a heat pump, due to the characteristics of the system, cooling performance is insufficient due to the efficiency limitation of the Peltier element, and the system Since the heat dissipation of the product is entirely dependent on the heat dissipation fan, it is difficult to downsize and has a big disadvantage such as noise during operation.

Domestic Patent Publication No. 10-2010-0088947

There is a need for a stabilization technique that safely discharges electricity to prevent power supply from disrupting.

The lithium ion battery used in the energy storage system is a secondary battery, and the technology for folding and manufacturing in the form of a folder to reduce the volume in the form of cells and modules in the early stage has been generalized.Although there are overcharge and overdischarge circuits during charge and discharge, cells, modules, There have been cases where packs are burned down.

In terms of fire-fighting and disaster prevention technology, lithium-ion batteries are folded inside the cell, so they are impaled by external shocks and sharps, and the active material of the separator and the ion plate inside the cell is short-circuited, causing short-circuit and ignition.

If heat generation is not dissipated through temperature reduction during heat generation, thermal runaway (170°C to 70°C or less) occurs in the battery cells, modules, and packs of the energy storage system due to the accumulated heat, which ignites and explodes, leading to the explosion of the power plant. Energy storage systems are often burned down.

Due to the thermal runaway phenomenon, there is a technical difficulty in dispersing and releasing heat quickly, and it is necessary to install an air conditioning system such as a chiller, which increases the installation cost and the maintenance cost.

In the case of energy storage systems, lithium ion batteries, not simple electric fires and metal fires, should be considered as chemical fires, and fire prevention and initial suppression facilities for early detection of fires (eg smoke detectors, temperature detectors) Example: sprinkler) must be installed and operated within a limited size.
