The invention discloses a state monitoring module for a mobile type power bank battery management system. The state monitoring module is formed by connecting multiple measuring units in series through a CAN bus; each measuring unit comprises a CPU, a voltage detection unit and a temperature detection unit. The state monitoring module for the mobile type power bank battery management system can be used for monitoring state parameters of a battery pack at the charging stage, the discharging stage, the storage stage and the transportation state, such as charging current, discharging current, voltage, temperatures, pressure and leakage current parameters.
