摘要: 在現(xiàn)今大部分后備電源(直流系統(tǒng)、UPS)中能量的儲存都是采用蓄電池組來實(shí)現(xiàn)的,那么作為不間斷供電最后保障的蓄電池組的充電就顯得至關(guān)重要了,我們提出采用對每節(jié)單體電池單獨(dú)充電和檢測的思路,用以解決由于蓄電池特性不一致引起的過充電,過放電、蓄電池檢測裝置不能很好的和充電裝置結(jié)合導(dǎo)致的不能科學(xué)的對蓄電池進(jìn)行充電以及充電中采用大容量高頻模塊實(shí)現(xiàn)困難,可靠性低三方面問題。

Abstract:All of storage of energy adopt battery in mothball electrical source such as direct current system and UPS now。It is very important that charging of battery that is last ensurance to uninterrupt power。We put forward charging soley for every unit battery to solve overcharging ,overdischarging, difficult realization and low reliability as a result of battery device haven’t combined charing device efficiently so that battery can’t be charged well and adpot bulky module in during of charging。
