Description

Battery Storage Device {Battery Storage Device}

The present invention relates to a battery storage device.

In modern society, as energy resources such as petroleum, coal, and natural gas are gradually depleted and environmental pollution is recognized as an important problem, efficient use of energy is emerging as an important issue. Accordingly, numerous efforts have been made to efficiently utilize energy. One of these efforts is an energy storage system.

An energy storage system is a system that increases energy efficiency by storing power generated in power plants, substations, transmission lines, etc. in a battery module and then selectively and efficiently using it when power is needed. Using an energy storage system, it is possible to equalize electric loads with large fluctuations in time and season. Through this, the overall load factor can be improved. And, it is possible to lower the unit cost of power generation. In addition, it is possible to reduce the investment cost and operation cost required for power facility expansion. In addition, electricity rates can be lowered and energy can be saved.

An important component for constructing such an energy storage system is a battery module.

Battery modules are largely classified into physical energy storage and chemical energy storage according to storage methods. As physical energy storage, there are methods using pumped storage, compressed air storage, and flywheels. And, as chemical energy storage, there is a method using a lithium ion battery, a lead acid battery, a Nas battery, and the like.

Recently, secondary batteries that can be repeatedly charged and discharged and can store energy have been widely used. Secondary batteries have a great advantage in that they can repeatedly store energy. In addition, a plurality of secondary batteries may be formed as one module according to the power consumption of the place where the secondary batteries are used. Using the advantages of these secondary batteries, various battery modules used in energy storage systems are being developed.

On the other hand, the battery module handles a large amount of power according to the power consumption of the place where it is used, so safety problems may occur. Also, since the battery module uses electrical energy and chemical energy, problems may occur in response to changes in the surrounding environment. Therefore, in order to protect the battery module from environmental factors and safety issues, it may be disposed in an internal space of a storage device or the like.

For example, Korean Patent Laid-open Publication No. 10-2012-0120650, “a battery storage device, a sub-storage device used therein, and a battery pack using the same” may be cited.

In the prior art, a technique of forming a sub-storage device combining a side plate and a support bar to accommodate a plurality of battery modules and forming a single storage device by stacking the sub-storage device is disclosed. In addition, the storage device formed as one is fixed only by being mounted on a separate fixing plate.

According to the prior art, it is inconvenient to separate the storage device formed into one in order to transport a plurality of battery modules. In addition, for maintenance of the battery module, it is necessary to separate the storage device formed into one unit.

In addition, the conventional storage device is only formed so that a plurality of battery modules are easily stacked, and there is a problem that it is vulnerable to water droplets penetrating into the inner space from the outside.

In addition, the conventional storage device has a problem in that the fixing plate and the side plate are interposed and coupled, so that the coupled portion is vulnerable to waterproofing.

Also, the other surface of the first extension part 24 may contact the fourth extension part 45 . At this time, in the third housing 40, a part of the first housing 20 is seated at a portion where one surface of the third housing 40 and one surface of the first extension part 24 meet. It may be referred to as section 49.

According to this structure, the first extension part 24 can come into contact with the fourth extension part 45 . In addition, since the fourth extension part 45 is formed upward from the first extension part 24, water droplets penetrate into the space between the first extension part 24 and the fourth extension part 45. that can be prevented

According to the present invention, it is possible to secure the safety of a battery accommodated inside the storage device, and to provide a battery storage device for convenient battery maintenance work. In addition, by forming a handle to facilitate transportation of the storage device, it is possible to approach the battery storage device that maximizes user convenience.
