The BMS battery management system is simply the steward of the battery, which plays important functions such as ensuring safety, extending the service life, and estimating the remaining power. It is an indispensable component of power and energy storage battery packs. , Reduce losses caused by battery damage.

The energy storage battery management system is very similar to the power battery management system. Most people do not know the difference between the power battery BMS management system and the energy storage battery BMS management system. Next, briefly introduce the difference between the power battery BMS management system and the energy storage battery BMS management system.

1. The position of the battery and its management system in the respective system is different

In Residential Energy Storage System, energy storage batteries only interact with high -voltage energy storage storage transformers, transformers from the AC power grid, charge the battery pack, or power the battery pack to the market. AC grid.

The communication and battery management system of Residential Energy Storage System mainly have information interaction with the degeneration and energy storage power station scheduling system. On the other hand, the battery management system sends important status information to a variable -changing current to determine the situation of high -voltage power interaction. On the other hand, the battery management system sends the most comprehensive surveillance information to the scheduling system PCS of the energy storage power station.

In terms of communication between electric vehicle BMS with energy switching with electric and chargers, electric vehicle BMS has information interaction with the charger during the charging process, and has the most detailed information interaction with the vehicle controller during all application processes.

2. The logic structure of hardware is different

Energy storage management system, hardware generally adopts two or three -layer modes, with a large tendency to three -layer management system. The power battery management system has only one layer of centralized or two layers of distribution, with almost no three layers. Small cars mainly use centralized battery management systems. Two layers of distributed power battery management systems.

From a functional point of view, the first and second -layer modules of the energy storage battery management system are basically equivalent to the first -layer collection module and the second main control module of the power battery. The third layer of the energy storage battery management system is the increase in increased on this basis, and the huge scale of energy storage batteries should be cope with. Merminating to the energy storage battery management system, the management capability is the computing power of the chip and the complexity of the software program.
