Energy storage battery BMS and lithium ion battery BMS -Lithium - Ion Battery Equipment
1 Application scenario of large -scale energy storage system
New energy power stations, wind power or solar power stations, in order to achieve the purpose of flat -input power fluctuations, more and more power plants have begun to equip energy storage systems.
Independent energy storage power stations have gradually entered people's vision with the reform of the power system, and independent energy storage power stations that live up to sell electricity have gradually appeared.
Micro grids contain a small power supply network in the system containing distributed power supply, power load, energy storage system and power grid management system. In order to ensure the continuity and stability of the load, each micro grid is equipped with an energy storage system.

2 The difference between energy storage battery management system (ESBMS) and power lithium battery management system (BMS)
The energy storage battery management system is very similar to the power lithium battery management system. However, the power lithium battery system is on electric vehicles with high -speed motion. It has higher requirements for the power response speed and power characteristics of the battery, the SOC estimation accuracy, and the number of status parameters.(Lithium - Ion Battery Equipment)
The energy storage system is very large, and the centralized battery management system is obviously different from the energy storage battery management system. Here, only the power lithium battery distributed battery management system is compared with it.
2.1 The positions of batteries and their management systems are different in their respective systems.
In the energy storage system, the energy storage battery only interacts with the energy storage transformer on the high voltage, and the transformer is required from the AC power grid to charge the battery pack; Convert the transaction distribution to the AC grid.
The communication system of the energy storage system has an information interaction between the battery management system and the transformer and the energy storage power station scheduling system. On the one hand, the battery management system sends important status information to a variable -changing flow to determine the interaction of high -voltage power; on the other hand, the battery management system sends the most comprehensive monitoring information to the scheduling system of the energy storage power station PCS.
2.2 Different hardware logic structure
Energy storage management system, hardware generally adopts two or three -layer models. The larger scale tends to the three -layer management system.
The power lithium battery management system has only one layer of centralized or two distributed formulas, and there will be no three layers. An important application of a small car for a layer of centralized battery management system.
From a functional point of view, the first and second layers of the energy storage battery management system are basically equivalent to the first layer of the power lithium battery and the second layer of the main control module. The third layer of the energy storage battery management system is a new layer based on this to cope with the huge scale of energy storage batteries.
It's not so appropriate to hit one. The best subordinate of a manager is 7 people. If the department has been expanding and 49 people have appeared, then 7 people choose one team leader and then appoint one manager to manage the 7 team leaders. Beyond your personal ability, management is prone to confusion.
Merminating the energy storage battery management system, this management capability is the computing power of the chip and the complexity of the software program.
2.3 The communication protocol is different
The energy storage battery management system and internal communication basically use the CAN protocol, but it has an external communication and external important refers to the PCS of the energy storage power station scheduling system, which often uses the Internet protocol format TCP/IP protocol.
The power of the power lithium battery, the electric vehicle environment of the electric vehicle is used in the CAN protocol, but the internal CAN can be used according to the internal components of the battery pack.
