Redundancy equalization lithium battery management circuit and method of genetic algorithm combined with K-means clustering

Abstract

The invention relates to a redundancy equalization lithium battery management circuit and method based on a K-means clustering genetic algorithm. The circuit comprises a single-chip microcomputer unit, and a switch driving unit, an AD sampling unit, a passive equalization driving unit and a Hall sensor which are connected with the single-chip microcomputer unit, and also comprises a battery pack module. The single-chip microcomputer unit collects data according to the AD sampling unit and the Hall sensor, controls corresponding switches through the switch driving unit and the passive equalization driving unit, and further controls all the lithium battery units and all the single lithium batteries in the battery pack module to participate in power supply of the whole redundant equalization lithium battery management circuit or not. The circuit has applicability, can solve the problem that the electric quantity of the discrete battery pack is inconsistent, and reduces the energy difference among the single batteries in the battery pack, thereby improving 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 a genetic algorithm of K-means clustering. 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, etc. The battery balance management is controlled by the voltage and current parameters of the lithium battery pack sampled and calculated by the single-chip computer, which can realize the balanced management of the charging and discharging process of the power lithium battery and when the parameters such as the voltage and temperature of the single battery are abnormal or damaged, the redundant The battery has replaced the faulty battery to ensure that the battery pack as a whole can be used normally. [0003] At present, redundant equa...
