Battery management control system and control method

Abstract

The invention discloses a battery management control system. The battery management system comprises a plurality of analog detection modules, a plurality of digital detection modules, a plurality of bypass modules, a plurality of switching control modules, a buck-boost module, a battery information acquisition module, a battery management module and a main control module, a plurality of switchingcontrol modules, a plurality of bypass modules and each battery module are additionally arranged to form a battery pack; when a certain battery module fails or the voltage detection signal is lower than a first preset value, the switching control modules control the battery module to be disconnected; the bypass modules corresponding to the battery module is switched and connected; therefore, otherbattery modules can form passages with the bypass modules; therefore, the battery pack is enabled to continuously perform normal charging and discharging, the battery management control system is enabled to still continuously and normally work when one or more battery modules break down, the grouping difficulty of the single batteries is reduced, the utilization rate of the battery modules is improved, and real-time dynamic balance of charging or discharging can be realized.

Description

technical field [0001] The invention belongs to the technical field of battery charge and discharge management, and in particular relates to a battery management control system and control method. Background technique [0002] At present, when a single battery works under different conditions such as temperature, charge and discharge rate, and state of charge, or as the number of charge and discharge of the battery increases, its voltage, capacity, internal resistance, and self-discharge rate will vary, making the battery The module is difficult to control during the charging and discharging process, and it is prone to overcharge and overdischarge, which not only affects the life of the entire battery module, but also increases the difficulty of grouping the battery cells; in addition, when one or more battery modules When a failure occurs, the entire battery management control system will be in a paralyzed state, resulting in the failure of all battery modules to work norma...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a battery management control system and control method, aiming to solve the problem in the battery management control system in the traditional technical solution that when a certain battery module fails, all battery modules cannot be put into operation normally
