Power management system based on BMS module

The invention, which relates to the technical field of power management, discloses a power management system based on a BMS module, comprising a data acquisition module, a data transmission module, a management center, a safety analysis module and an operation and maintenance management module. The data acquisition module is used for acquiring power battery data in real time; the data screening module is used for carrying out data cleaning on the collected power battery data, intercepting a slow charging segment from a continuous voltage and current curve as target data and caching the target data to a terminal database; the data transmission module is used for transmitting the cached target data to a management center in combination with a target transmission mode, so that the data transmission efficiency is improved; the safety analysis module is used for acquiring power battery data, performing battery load analysis and judging whether battery charging and discharging are abnormal or not; a manager is remi
