Description

[0001] ESS BATTERY RACK [0002]

The present invention relates to an ESS battery storage apparatus which is easy to install and maintain, and which absorbs vibration when an earthquake or the like is generated to prevent breakage of a large number of ESS batteries.

Energy demand has been on an increasing trend every year due to recent high oil prices and widespread use of heating and cooling equipment due to unusual climate change. In addition, the demand for energy, quality of life, and service upgrading demands new energy demand continuously, and direct power dependency is intensified, which can cause power supply shortage. Especially, every summer and winter, There are power problems such as 'energy saving'.

In addition, since many domestic energy sources depend on crude oil and nuclear power, improvement of energy supply and demand is urgent national task.

ESS (Energy Storage System) is one of the ways to solve this power crisis. ESS can save electricity generated by surplus production or make electricity produced by using renewable energy available at required time As a device, idle power can be stored at a time when electricity demand is low, and power can be stably supplied by supplying electricity at a time when demand is high.

Therefore, by storing electric energy and using it when needed, it improves the efficiency of energy use, improves the utilization of new and renewable energy, and stabilizes the power supply system. Therefore, the importance of ESS, which is one of the new growth engine industry, is getting attention.

An ESS battery RACK having a predetermined storage structure for storing and storing such ESS in pack form has been developed and used. ESS Battery RACK has an appropriate structure to prevent damage of ESS from various external environments including vibration. Expansion of exponential market and safety of ESS battery rack as a national task are as important as ESS Has been highlighted.

In Korea, most civil facilities are very vulnerable to earthquakes, and earthquake application standards are in place, but facilities are not being reinforced. Damage to earthquakes occurs in public as well as in Japan, which we know well. There are various damage cases regardless of the magnitude of the earthquake, but in the primary aspect, power outages cause huge inconveniences and damage to industries.

In addition to the power outage caused by the general electricity demand, as mentioned above, the earthquake-induced power outage is more damaging. ESS (Energy Storage System) is a spare battery Can be utilized.

However, the existing Rack Type ESS battery rack manufactured by the integral welding method takes a long time to manufacture and the manufacturing cost is high. In addition, it can not be replaced partly due to the nonconformity of the component, which increases the manufacturing cost, and it is vulnerable to vibration, thus failing to guarantee the safety of the internal ESS device. Also, it is deformed due to weak corrosion and durability. It often leads to destruction.
