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.
