The utility model provides a real-time alarm system of magnanimity energy storage battery data exception, including host node, processing node and warning node. The host node direct data acquisition and monitored control system (SCADA) with energy storage battery dock, acquires the real-time data of hundreds thousand of monitoring points through the real-time communication network, there are a plurality of processing nodes in the real-time alarm system, acquire the real-time data of host node distribution through the internal network to carry out monitoring unusually, the warning node acquires each processing node to unusual some information processing result through the internal network to give data acquisition and monitored control system through outside communication with real-time unusual some information transfer, reach the warning purpose. Real-time alarm system on line real-time processing magnanimity the battery data with provide real-time alarming function, can guarantee that the battery just can obtain handling in the very first time unusually, ensured that the battery is healthy to move that messenger's battery energy storage power station is the safety and stability more.
