The invention discloses a cooperative control system for a marine power lithium battery device and a control method of the cooperative control system. The system is based on a general control, master control and slave control three-level control mode, considers the problem of collaborative control of a power system of the whole ship, solves the problem of collaborative control and management of a ship lithium battery pack through internal grading and external collaborative strategies, and ensures that a lithium battery device provides guarantee for safe operation of the ship; a modularized data acquisition unit is arranged, different sensing devices are matched with a processing circuit, the requirement for multi-type data or signal acquisition is met, and the system supports data processing of the battery state and SOC/SOH estimation of the battery state of charge of a battery pack; the real-time data information of the slave control battery is acquired and processed through a CAN (Controller Area Network); management and control of charging and discharging of the battery pack are achieved after processing is completed; two paths of total voltage detection of the battery end and the load end are adopted, voltage sampling is reliable, detection errors are small, and overvoltage and undervoltage protection is supported through threshold value comparison.

    本发明公开了一种船用动力锂电池装置协同控制系统及其控制方法。系统基于总控、主控和从控三级管控模式,考虑整船电力系统协同管控问题,通过内部分级、外部协同的策略,解决船舶锂电池组协同控制与管理问题,确保锂电池装置为船舶安全运行提供保障;设置模块化数据采集单元,通过不同传感器件与处理电路配合,满足多类型数据或信号采集需要,系统支持对电池状态的数据处理,支持对电池组的电池荷电状态SOC/SOH估算;支持通过CAN获取并处理从控电池实时数据信息;完成处理后实现对电池组充放电的管理及控制;采用电池端和负载端2路总电压检测,采压可靠且检测误差小,通过阈值比较,支持过压、欠压保护。
