關于蓄電池組充電的思考

摘要：　　在現今大部分后備電源（直流系統、UPS）中能量的儲存都是采用蓄電池組來實現的，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重要了，我們提出采用對每節單體電池單獨充電和檢測的思路，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合導致的不能科學的對蓄電池進行充電以及充電中采用大容量高頻模塊實現困難，可靠性低三方面問題。 敘詞：高頻開關電源；IGBT MOS-FET；記憶效應；N+1冗余備份；浮充電；熱插拔 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。 Keyword：High frequency switch power supply;IGBT MOS-FET;Memory domino offect;N+1 redundant stock;Float charging;Hot insert and draw
