Abstract

A pile charging balance management system and operation method thereof is provided, which includes an external charging equipment, and which is characterized in that it is comprised by a data processing unit, a charging balance regulation executing unit, a battery state sampling unit, a system power supply identification reference unit, a charging state indicating unit; and its operation method is as follow: a CPU analyses the voltage of each cell of the pile and then adjusts each cell to balance the same. The advantage and the technical effect of the invention rests with realizing real time sampling for the voltage of each cell of the pile and effective variable current adjusting to each cell, keeping balance of the same in charging, so that the service life can be prolonged, and the invention has widely application prospect.

Description

(1) Technical field: [0001] The invention belongs to the field of batteries, in particular to a charging balance management system for a battery pack and its working method, especially a battery pack composed of lead-acid, nickel metal hydride, lithium ion, lithium ion polymer and other secondary batteries, aiming to play A management system for battery potential and extended battery pack life. (two) background technology: [0002] At present, the performance difference between the individual cells of the battery pack is small at the beginning of use, but in use, with the increase in the number of charging cycles, these differences will be gradually enlarged, and eventually the battery pack will be scrapped, which is a waste of resources and a waste of time. Not conducive to environmental protection. The reason is that whether it is three-stage charging or several-stage charging, it is a series charging of the battery pack as a whole, which cannot meet the technical require...
