关于铅蓄电池充电电流接受率的研究

电流接受率反映了电池的充电性能，在马斯理想充电曲线上的电流接受率在实际充电中是很难达到的。实际的电流接受率总是与理想值存在差距，在某阶段会高于理想值，在某阶段又会低于理想值。在“恒流-恒压”充电过程中，电池的端电压U1=E＋I1（R1＋R2）。由于充电初期极化微弱，在忽略R1与R2的影响后，把电池的端电压近似为电极电势。当极化并不显著时，可以用电压的上升速度来衡量电流的接受率。得到“电压上升越快，电流衰减越快，电流接受率越好”的结论。

Study on the charging currentreceptance for lead-acid batteries

Charging current receptance reflected charge performance of battery.It is very hard to obtain the Maas ideal charge curve.There is difference between practical current receptance and ideal value.Terminal voltage of charge is U1=E I1(R1 R2)during the course of "constant current-constant voltage" charge.During the early period,as a consequence of polarization faint,we may take terminal voltage of charge as electrode potential when overlooking effects of R1 and R2.We may scale current receptance with ascending of voltage when polarization becomes not noteworthy.Consequently,we come to a conclusion that the quicker voltage uptrends,the quicker current decays,thus the current receptance becomes better.
