First of all, the complete electrochemical energy storage system is mainly composed of battery pack, battery management system (BMS), energy management system (EMS), energy storage converter (PCS) and other electrical equipment, among which the battery pack is the most important component of the energy storage system and also the link with the largest cost.
Let's look at the battery pack first. Energy storage and photovoltaic also have an industrial chain. The battery pack is in the middle of energy storage. Its role is mainly to monitor, evaluate, protect and balance the battery. How much is the cost?
In the composition of energy storage system, the battery with cost accounting for 60% is undoubtedly the most valuable link. The leading companies such as Ningde Times and BYD have obvious advantages.
The second is the energy storage converter (PCS), which is the core component of the energy storage system, accounting for about 20% of the cost. Its main function is to control the charging and discharging process of the energy storage battery pack, and carry out AC/DC conversion.
The third is the energy management system (EMS), which is mainly responsible for data acquisition, network monitoring and energy scheduling.
In addition, how does the energy storage system prevent fire and extinguish fire? It is also a topic of great concern.
The fire protection system is also very important. Yes, don't look down on this box. There is also a fire protection system inside. Someone said: Since there is a fire protection system, there are so many fire news?
In fact, the energy storage battery fire should be detected and controlled as early as possible. In case of an accident, the fire should be controlled within a certain range as far as possible. The main function of the fire protection system is to cut off the fire source as soon as possible to avoid spreading to the surrounding area, leading to the expansion of the accident.
As mentioned above, the energy storage system adopts a walk-in design. What is "walk-in"? Generally speaking, it means opening an escape door where people can go in and out, and a corridor where people can walk in the middle.
Someone said, "I have seen a box without a door."
Yes, since there are "walk-in" and "non walk-in", what are the design features of containers with non-walk-in design? First, the temperature difference between battery clusters is small; External maintenance of all components of the container, high safety; Save safe escape space and improve the utilization rate of container space.
With regard to the design of energy storage system containers, some can even be customized (high cost), and the internal structure may not be exactly the same. To be more intuitive, the small box asked the industry's mature energy storage solution providers. Taking the 0.5MW/1MWh energy storage system as an example, the configuration list is attached for your reference.
