摘要(Abstract)：

随着大容量、高功率密度储能的需求增长，液冷式储能成为行业发展趋势。液冷式电池模组容量大、电芯数量多、系统电压高，对电池管理系统实现电池数据采集、系统控制管理与系统运维功能提出了更高要求。提出了一种基于液冷一体储能系统的电池管理系统，介绍了整个系统通信架构以及各级管理单元的设计，阐述了各单元的功能配置。对比目前市场常见的4种被动均衡方案所存在的局限性，按照外置MOS的方案设计了被动均衡电路，实现了均衡控制并减少了人为补电操作。提出的系统已在实际工程中得到应用，获得了完整充放电循环数据曲线，验证了系统的可实施性。
With the increasing demand for energy storage with large capacity and high power density, liquid-cooling energy storage has become the development trend of the industry. Featuring large capacity, large number of electrodes, and high system voltage, the liquid-cooling battery module makes higher demands on the battery management system in terms of battery data acquisition, system control management, and system operation and maintenance functions. This paper presents a battery management system based on a liquid-cooling integrated energy storage system. It introduces the communication architecture of the system and the design of management units at all levels and expounds the functional configuration of each unit. Four passive equalization schemes in the market are compared concerning their limitations. A passive equalization circuit is developed based on the external MOS to realize the equalization control and reduce the manual power supply. The proposed scheme has been applied to practical engineering. A complete data curve of the charging and discharging cycle has been obtained to verify the practicability of the system.
