2.2.2 BMS
As the core component of energy storage systems for collection, control, and protection, BMS is divided into a three-level architecture, including
BAU , B C U , B M U
BAU conducts comprehensive management and coordination of multi cluster battery systems. It integrates the functions of BMU and BCU, and has more advanced features such as fault diagnosis and warning, system status assessment, etc. BAU can also communicate with external systems to achieve remote monitoring and management
BCU is generally placed in the high-voltage box of the battery cluster to achieve real-time monitoring of the total voltage, total current, insulation resistance, and internal temperature of the high-voltage box of the battery cluster. At the same time, it summarizes the voltage, temperature, and other information of individual cells in the cluster to estimate the SOC/SOH of the battery cluster, perform balancing strategy judgment, battery fault diagnosis and alarm, and realize on-site protection and relay control of the battery cluster based on the battery fault information. Finally, it exchanges information with EMS, PCS and other equipment through CAN/RS485 communication interface. When the battery cluster experiences serious overvoltage, undervoltage, overcurrent (short circuit), overheating, leakage (insulation) and other abnormal faults, the BCU can effectively control the disconnection of the battery cluster, avoiding overcharging, overdischarging, overheating, overcurrent, and ensuring the efficient, reliable, and safe operation of the energy storage system.
BMU provides real-time monitoring of single cell battery voltage and temperature, as well as balancing capability. It forms a highly flexible battery management system (BMS) through daisy chain communication and battery cluster management unit (BCU).
2.2.2.1 Main functions of BCU
The main control unit is mainly composed of the following parts: auxiliary power conversion, MCU and peripheral circuits, real-time clock, total voltage and insulation monitoring, charge and discharge current detection, external relay (contactor) drive and detection, communication interface, etc. The main functions include: detection of total voltage of the battery pack, detection of charging and discharging current of the battery pack, detection of insulation resistance of the battery pack to ground, management of battery pack charging and discharging, thermal management of the battery pack, real-time dynamic estimation of SOC and SOH, system self check and fault diagnosis alarm, safety protection for various abnormal and fault situations, communication with other devices such as PCS and EMS, data storage, transmission and processing, storage of recent alarm information, reset information, and sampling abnormal information of the system. The stored information can be exported as needed. During the charging and discharging process of the system, the temperature of individual cells is monitored, and there are alarms for high or low cell temperature, or large temperature difference between cells. When a second level alarm occurs, the alarm information is actively reported. When a third level alarm occurs, the system automatically cuts off the contactor.

2.2.7 Fire Protection System
The use of aerosol fire extinguishing devices in the fire protection system is a new environmentally friendly fire protection product with world advanced level. Working principle: When the ambient temperature reaches the starting temperature of the thermal wire or comes into contact with an open flame, the thermal wire self ignites and is transmitted to the aerosol series fire extinguishing device. After receiving the start signal, the aerosol fire extinguishing device activates the internal fire extinguishing agent, rapidly producing nano aerosol fire extinguishing agent and spraying it out, achieving rapid fire extinguishing. The parameters of the fire protection system are as follows:
