Redundant balanced lithium battery management circuit and method based on genetic algorithm combined with k-means clustering

Abstract

The invention relates to a redundant balanced lithium battery management circuit and method combined with K-means clustering genetic algorithm. The circuit includes a single chip unit, a switch drive unit connected to the single chip unit, an AD sampling unit, a passive equalization drive unit, a Hall sensor, and a battery pack module; the single chip unit collects data according to the AD sampling unit and the Hall sensor, The corresponding switches are controlled by the switch drive unit and the passive balance drive unit, thereby controlling whether each lithium battery unit and each single lithium battery in the battery pack module participate in the power supply of the entire redundant balanced lithium battery management circuit. The invention has applicability, can solve the problem of inconsistent power of discrete battery packs, reduce the energy difference between the battery cells in the battery pack, and improve the consistency of the battery pack.

Description

technical field [0001] The invention relates to a redundant balanced lithium battery management circuit and method combined with K-means clustering genetic algorithm. Background technique [0002] Redundant balanced lithium battery system: Redundant balanced lithium battery system is a power lithium battery management system: including lithium battery pack, main control unit, data acquisition unit, bus, host computer and display unit. The voltage and current parameters of the lithium battery pack sampled and calculated by the single-chip microcomputer are used to control the battery balance management, which can realize the balanced management of the charging and discharging process of the power lithium battery, and when the voltage, temperature and other parameters of the single battery are abnormal or damaged, the redundant The battery has replaced the faulty battery to ensure the normal use of the battery pack as a whole. [0003] At present, redundant equalization is a ...
