韩国MXCARBON蓄电池电力电站应急配套电源

缺点是初始充电电流过小，充电后期 充电电流又过大充电时间长、析出气体多、对极板的冲击较大、能耗较高、效率较低(不超过65%)，在充电过程中需有人看守，一般在初充电和在小电流进行去硫充电才使用。因恒流充电的变型是分段恒流充电，充电时为防止充电后期电流过大，应及时调整充电电流，还应注意充电电流的大小、充电时间、转换电流的时机及充电终止电压的选取等。

充电过程中由于不能调整充电电流，不适用于UPS蓄电池的初充电和去硫充电。充电过程中对UPS蓄电池电压的变化很难补偿，对容量恢复较慢的UPS蓄电池完全充电很难完成。

The characteristic ofpulse fast charging is to use 1-2 times the C20A high currentcharging, so that the UPS battery can be charged to 50% to 60% ofthe rated capacity in a short period of time. When the single cellvoltage of the UPS battery reaches 2.4V, it stops charging and isautomatically switched to pulse charging by the control circuit;First stop charging for 25-40ms (stop charging before), thendischarge or reverse charge, causing the UPS battery to passthrough a large pulse current in the opposite direction (pulsedepth is 1.5-3 times the charging current, pulse width is150-1000um), then stop charging for 25ms (stop charging later), andso on until sufficient.
