催化栓对VRLA电池高温浮充性能的影响

Effect of catalytic plug on high-temperature performance of VRLA battery under floating-charge duty

比较安装和未安装Pd-C催化栓的浮充型GFM-600阀控式铅酸(VRLA)电池的高温浮充性能。安装催化栓后,电池的高温(55℃)浮充(2.25 V/只)电流下降约50%,失水量减小约65%,寿命得到延长。

The high-temperature floating-charge performance of floating-charge type GFM-600 valve regulated lead-acid （VRLA） batteries with or without Pd-C catalytic plugs was compared. By using catalytic plugs, the high-temperature （55 ℃ ） floating charge （2.25 V/cell）current was decreased by about 50%, the water loss was reduced by about 65%, the cycle life was prolonged.
