Abstract

The invention discloses a method and a system for carrying out load balancing control on a plurality of battery units. The method comprises the following steps: acquiring historical use data of each battery unit in a plurality of battery units in a first preset time period; calculating the initial health degree of each battery unit according to the acquired historical use data of each battery unit; determining a current state parameter of each battery unit; calculating the dynamic health degree of each battery unit according to the initial health degree of each battery unit and the current state parameter of each battery unit; and performing descending sort on the dynamic health degree of each battery unit, and determining the use priority of each battery unit according to a descending sort result so as to determine the use sequence of each battery unit according to the use priority of each battery unit. By determining the use priorities of the battery units in the charging and discharging processes, the service lives of all the battery units in the battery pack are consistent, so that the service life of the battery pack is prolonged.

Description

technical field [0001] The present invention relates to the technical field of battery usage, and more specifically, to a method and system for load balancing control on multiple battery units. Background technique [0002] As a reliable chemical power source, batteries are widely used in equipment in transportation, aerospace, electric power, communication, military industry and other departments. Among them, lead-acid battery has always maintained its leading position in the battery industry due to its mature technology, high electromotive force, large discharge current, wide temperature range, stable performance, reliable operation, low price and abundant raw material sources. Especially in electric vehicle power source, industrial and mining electric locomotive power source, electric locomotive, automobile starting power supply, etc., it has been more widely used. [0003] Most of the power batteries of existing power equipment are battery packs including a plurality of...
