Abstract

A pile management system includes an electromotion execution device and an outer charging device and an outer discharging device, and which is characterized in that: it is comprised by a data processing unit, a charging balance regulation executing unit, a discharge control execution unit, a battery state sampling unit, a system power supply identification reference unit, a charging state indicating unit. Its operation method is as follow: a CPU analyses the voltage of each cell of the pile and then adjusts the balance of each cell. 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 charge and discharge, so that the service life can be prolonged, and the invention has widely application prospect.

Description

(1) Technical field: [0001] This system belongs to the field of batteries, especially a battery pack management system and its working method, especially for battery packs composed of lead-acid, nickel metal hydride, lithium-ion, lithium-ion polymer and other secondary batteries, aiming to develop the potential of the battery , A management system that prolongs the life of the battery pack. (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 and discharging cycles, these differences will gradually increase, eventually leading to the scrapping of the battery pack, which is a waste of resources. It is not conducive to environmental protection. The reason is that in the charging and discharging link, no matter the three-stage charging or the several-stage charging, it is the series charging of the battery pack as a ...
