Abstract

The invention relates to the technical field of battery management, in particular to a BMS equalization battery management control system, method and circuit. The BMS equalization battery management control system comprises an energy storage module, a charging module, a detection module and a thermal management module; the energy storage module is formed by connecting a super battery pack and a common battery pack in parallel, the charging module is electrically connected with a charger and the energy storage module, and hybrid charging is performed through the super battery pack and the common battery pack. The detection module is electrically connected with the master controller and is used for detecting the residual electric quantity of the super battery pack and the common battery pack, the heat management module is electrically connected with the slave controller and is used for adjusting the temperature according to the temperature data, and the temperature in the battery box is adjusted through the heat management module, so the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a BMS balanced battery management control system, method and circuit. Background technique [0002] Energy shortage is an important issue affecting the development of my country's national economy, and it is also a concern of the whole world. Energy conservation and emission reduction is a long-term strategic policy for my country's economic and social development, and it is also an extremely urgent task at present. my country's new energy vehicle power batteries account for more than 85% of the world's total, and improving power battery packs is of great importance. Taking into account the advantages of my country's rich rare earth resources and the world's leading battery production, it is imperative to develop high-energy, fast-charging, ultra-universal and long-range modular composite power battery packs. [0003] The charging of existing electric vehicles takes ...
