What is a lithium battery power storage system?

Lithium battery energy storage system Large-scale energy storage system is an important part of future new energy systems and smart grids, and energy storage batteries are the key to large-scale energy storage systems. Lithium batteries have the advantages of high energy density, long cycle life, low self-discharge rate, no memory effect, and environmental protection, and have broad application prospects in the field of energy storage. At present, lithium battery technology mainly includes different types of lithium cobalt oxide, lithium manganate, lithium iron phosphate, and lithium titanate. From the perspective of market application prospects and technology maturity, lithium iron phosphate batteries are recommended as the first choice in the field of energy storage. Hefei lithium battery manufacturers and suppliers say, what about lithium battery energy storage systems? 1. Electric energy storage systems are equivalent to battery energy storage. There are many applications, such as power systems in power stations, communication base stations and data rooms for backup power sources. The backup power technology and power battery technology of the communication base station and data room belong to the direct current technology, which is lower than the power battery technology. The content of energy storage technology is more extensive. In addition to DC technology, it also includes converter technology, grid access technology and grid dispatching control technology. Therefore, the ability to design power lithium-ion batteries may not necessarily be able to design power storage systems. At present, the energy storage industry has no clear meaning on what is electrical energy storage. In my opinion, the energy storage system should have two characteristics: 1) The energy storage system can participate in grid dispatch (or the energy in the energy storage system can be fed back to the main grid). 2. Compared with power lithium-ion batteries, lithium batteries for energy storage have lower performance requirements, which is hard to say. The important reason is that there is currently no recognized successful commercial energy storage project in China, so what kind of battery can meet the application of energy storage is still unknown. At present, my country is more interested in using decommissioned power lithium-ion batteries for energy storage. There have been some small-scale demonstration projects. The sources of these projects and the actual operation of the projects are not known to the outside world. Interestingly, well-known foreign battery companies, such as LGC and Samsung SDI, have already applied several GWh projects in the field of energy storage. At the same time, they are also recognized as the world's leading power lithium-ion battery company, and there is no report on their use in the media. Foreign car companies, such as BMW, are keen on the cascading use of batteries. Therefore, the application of the decommissioned power battery cascade in the field of energy storage needs further verification and observation. Currently, domestic lithium battery companies generally have not established independent energy storage Ru0026D teams. Energy storage research and development is generally carried out by the power lithium-ion battery team in the spare time of the power lithium-ion battery project. Even if there is an independent energy storage Ru0026D team, the energy storage team will be smaller than the power team. Compared with the power lithium-ion battery, the technical feature of the energy storage system is high voltage (generally designed according to 1Vdc requirements), and multiple single-cell batteries are connected in series and parallel. Therefore, the electrical safety and battery status monitoring of the energy storage system are more complicated and require specialized personnel to study and solve them.
