【摘要】：铅酸蓄电池以其容量大、寿命长、性价比高、输出电压稳定等优点被广泛应用于各个领域,其充电控制策略在铅酸蓄电池使用过程中占有极其重要的地位,也是当今蓄电池领域研究的热点问题之一。因此,研究铅酸蓄电池快速充电具有现实意义。论文深入分析了铅酸蓄电池工作原理、充电过程中极化现象产生的原因,以及如何消除极化现象;又以马斯理论为基础,归纳总结了各种铅酸蓄电池充电控制策略的特点和应用场合,包括恒压充电、恒流充电、阶段式充电、变电流间歇充电、变电压间歇充电、单相脉冲充电、正负脉冲充电、混合式充电等。在此基础上提出了一种新型铅酸蓄电池快速充电控制策略——带负脉冲多阶段充电控制策略,又根据马斯三定律,论证了所提控制策略对铅酸蓄电池进行快速充电的可行性,并定量计算了带负脉冲多阶段充电控制策略的各阶段充放电参数。为验证所提充电控制策略,提出了降压斩波电路加小电阻放电的主电路方案,对主电路进行了小信号建模,设计了补偿网络,并在MATLAB/Simulink中搭建仿真模型进行仿真,验证该电路结构能实现所提出的充电控制策略。搭建了研究铅酸蓄电池快速充控制策略实验平台,并进行了实验研究,实验数据表明,采用所提出的带负脉冲多阶段充电控制策略平均充电时间为232min,比采用普通恒流充电所用的平均时间减少了 7小时左右,验证了所提出的带负脉冲多阶段充电控制策略,能在不影响铅酸蓄电池寿命的前提下实现铅酸蓄电池快速充电。
[Abstract]:Lead-acid battery has been widely used in various fields because of its large capacity, long life, high performance to price ratio, stable output voltage and so on. The charging control strategy plays an extremely important role in the use of lead-acid battery. It is also one of the hot issues in the field of battery. Therefore, it is of practical significance to study the rapid charging of lead-acid battery. The working principle of lead-acid battery is deeply analyzed in this paper. The reason of polarization phenomenon in charging process and how to eliminate polarization phenomenon; On the basis of Mas theory, the characteristics and applications of various charging control strategies for lead-acid batteries are summarized, including constant voltage charging, constant current charging, stage charging and intermittent charging with variable current. Variable voltage intermittent charging, single-phase pulse charging, positive and negative pulse charging, hybrid charging, etc. Based on this, a new rapid charging control strategy of lead-acid battery with negative pulse multi-stage charging control strategy is proposed. The feasibility of the proposed control strategy for the rapid charging of lead-acid batteries is also demonstrated according to the Masthree law. The charging and discharging parameters of the multi-stage charging control strategy with negative pulse are calculated quantitatively. In order to verify the proposed charging control strategy, the main circuit scheme of the step-down chopper circuit with small resistance discharge is proposed. The main circuit is modeled with small signal, the compensation network is designed, and the simulation model is built in MATLAB/Simulink. It is verified that the circuit structure can realize the proposed charging control strategy. An experimental platform is built to study the rapid charging control strategy of lead-acid battery, and experimental research is carried out, experimental data show that. The average charging time of the proposed multi-stage charging control strategy with negative pulses is 232 mins, which is about 7 hours less than that of conventional constant current charging. It is verified that the proposed multi-stage charging control strategy with negative pulses can realize the rapid charging of lead-acid batteries without affecting the life of lead-acid batteries.
