铅酸蓄电池脉冲活化充电研究

Research on Pulse Activation Charging of Lead-Acid Batteries

铅酸蓄电池在使用过程中总是伴随着硫酸铅的沉积与溶解,在长期的使用过程或者不正确的操作下,会造成硫酸铅在极板表面的大量沉积,影响其寿命和效能。采用脉冲电流充电是现在常用的充电方式,能够有效缓解蓄电池的硫化问题。本文通过建立蓄电池电化学模型,对蓄电池脉冲充电过程中内部结构变化的仿真分析设计能够有效修复硫化铅酸蓄电池的充电曲线,同时设计充电电源电路拓扑。经过仿真实验分析,结果表面,本文所提出的充电方式能够有效去除电池极板表面硫酸铅,达到活化效果。

Lead-acid batteries are always accompanied by the deposition and dissolution of lead sulphate during use. Over a long period of time or under incorrect operation, this can result in the deposi-tion of large amounts of lead sulphate on the surface of the pole plate, affecting its life and effi-ciency. The use of pulsed current charging is now a common charging method that can effectively alleviate the sulphation problem of batteries. In this paper, we design a charging curve that can effectively repair sulphated lead-acid batteries by establishing an electrochemical model of the battery and simulating and analysing the internal structural changes during the pulse charging of the battery, as well as designing the charging power supply circuit topology. After simulation and experimental analysis, the results surface that the charging method proposed in this paper can effectively remove the lead sulphate from the surface of the battery pole plate and achieve the activation effect.
