汽车铅酸蓄电池低温大电流放电性能研究概况

Development Status of the Cold-Cranking Performance of Automotive Lead-Acid Batteries

本文综述了汽车铅酸蓄电池低温大电流放电性能的研究现状。近期研究表明，温度对正、负极板在低温下的放电容量及充电接受能力有极大的影响，且影响的程度各不相同；提高冷起动性能的主要方法是改进电池的结构；此外，还建立了计算机模拟电池低温放电过程的数学模型。

This paper reviewes the status of study on the cold-cranking(CCA) performence of automotive lead-acid batteries.It was showed: the temperatures has strong and different effect on the discharge capacity and charge receptibility of positive and negative electrodes. The main method of improvement on the CCA performance of an automotive battery is to change the batteryconfiguration. In addition, mathematical model can simulate thedischarge process.
