Battery safety monitoring method based on BIT and BMS data interaction

According to the battery safety monitoring method based on BIT and BMS data interaction provided by the invention, through the data interaction of the BIT and the BMS, when the battery modules are mixed and merged each time, the influence of the historical mixing and merging times and the mixing and merging feasibility of the available balanced power pack on the power supply loss of the finally constructed mixed and merged battery pack on the electric equipment is considered; therefore, each time of mixing takes the condition that the performance of the battery module is improved to the greatest extent, and the set condition that the battery module is added into the dependency unit set can represent the suspected fault generation characteristic of the battery module. Therefore, in the application, whether the battery module is suspected to have a fault can be quickly and accurately identified only by judging whether the number of times of adding the battery module into the dependency unit set during the inter
