The invention belongs to the technical field of a storage battery pack management system, and particularly relates to a novel topological structure of an on-line remote checking capacity experiment and a control method of the novel topological structure of the on-line remote checking capacity experiment. The novel topological structure is provided with a battery management system integrating a single storage battery parameter collection sub system, a battery analysis and calculation sub system and an overall monitoring upper computer system. A battery pack is connected with a data collection DAQ module; the DAQ module is connected with a microprocessor through a CAN bus, and is then connected with an upper computer; the DAQ module obtains battery unit data and transmits the data to the microprocessor; and the microprocessor implements analysis calculation of the storage battery pack checking capacity experiment, and transmits the battery pack state to the upper computer. A remote operation function is realized; the cost is reduced; the energy is saved; and high incident response capability is realized. In the checking capacity experiment process, the storage battery pack is connected with a direct current bus all the time; and high incident resisting capability is realized. If an incident occurs during the checking capacity experiment, the storage battery pack can still supplyelectricity continuously.
