A Collaborative Design and Modularized Assembly for Prefabricated Cabin Type Energy Storage System With Effective Safety Management Chen Chen1*, Jun Lai 2and Minyuan Guan 1State
The experimental setup employed in this study consists of four main components: the experimental chamber, the heating system, the signal acquisition system, and the inert gas displacement system
The battery cabin also included an energy management system (EMS), a safety monitoring management system (SMMS), as well as safety protection systems such as fire fighting system (FFS), temperature control system (TCS), electrical protection control system (EPCS) and uninterrupted power supply (UPS).
The EMS is mainly responsible for aggregating and uploading battery data of the energy storage system and issuing energy storage strategies to the power conversion system. These actions help it to strategically complete the AC-DC conversion, control the charging and discharging of the battery, and meet the power demand.
Several important parameters describe the behaviors of battery energy storage systems. Capacity [Ah]: The amount of electric charge the system can deliver to the connected load while maintaining acceptable voltage.
As shown in Fig. 1, the battery cabin has a total capacity of 1.75 MW and operates at a DC voltage of 1280 V. It consists of 10 battery cabinets, each connected to the high-voltage bus through a branch line equipped with electrical protection devices such as DC contactors, circuit breakers, and fuses.
As a result, battery energy storage systems (BESSs) are becoming a primary energy storage system. The high-performance demand on these BESS can have severe negative effects on their internal operations such as heating and catching on fire when operating in overcharge or undercharge states.
It is possible for an energy storage system with a good storage technology to perform poorly when implemented with a suboptimal architecture, while other energy storage systems with mediocre storage technologies can perform well when implemented with superior architectures.
