The invention discloses an electric bicycle battery charging and discharging state intelligent on-line monitoring fireproof protection system which comprises three functional units including a battery monitoring unit, a control and execution unit and an aerosol fire extinguishing unit. The battery monitoring unit comprises a single battery monitoring module, a storage battery monitoring convergence module, a group voltage current temperature monitoring module and a combustible gas monitoring module, and the single battery monitoring module can measure the single voltage, the single internal resistance and the single pole temperature of a single storage battery at the same time, so that the equalization charging function of the storage battery is realized; according to the invention, parameters such as voltage, current and internal resistance of the storage battery are monitored, a storage battery internal resistance model is constructed, storage battery health state diagnosis and tracking functions are realized, storage battery operation parameters and combustible gas are monitored, a storage battery thermal runaway model is constructed, and storage battery thermal runaway diagnosis and tracking functions are realized. Multi-level management of the thermal runaway abnormity of the storage battery is realized through normal state tracking, general abnormity early warning and emergency abnormity power-off protection of the thermal runaway of the battery.

    本发明公开了一种电动自行车电池充放电状态智能在线监测防火保护系统,包括电池监测单元、控制与执行单元以及气溶胶灭火单元三个功能单元,电池监测单元包括单电池监测模块、蓄电池监测收敛模块、组压电流温度监测模块、可燃气体监测模块,其中,所述单电池监测模块可同时测量单体蓄电池的单体电压、单体内阻及单体极柱温度,实现蓄电池的均衡充电功能,本专利通过对蓄电池的电压、电流、内阻等参数的监测,构建蓄电池内阻模型,实现蓄电池健康状态诊断与跟踪功能,通过对蓄电池运行参数及可燃气体的监测,构建蓄电池热失控模型,通过对电池热失控的正常状态跟踪、一般异常预警、危急异常断电保护实现蓄电池热失控异常的多层次管理。
