钒电池充放电测试系统及测试方法研究

为了检测钒电池的充放电性能,根据全钒液流电池的特点,标称出钒电池的额定参数。在不同电流密度下对单体钒电池进行充放电容量测试实验。比较了不同电流密度下的充电曲线,从理论上分析充电差异的原因,总结充电电流与钒电池容量的关系。实验表明,对钒电池进行充放电时采用的电流密度为60~80 m A/cm2之间的值,钒电池电学性能参数最佳。

Research of Charge and Discharge Test System and Test Method for Vanadium Redox Flow Batteries

Based on the characteristics of the vanadium redox flow batteries, the charge and discharge capacity tests at different current densities were conducted on a vanadium redox flow battery for detection of the charge and discharge performance and rating the nominal parameters of vanadium redox flow batteries. The relationship between the charging current and vanadium battery capacity was summarized by theoretical analysis of the charging differences and comparison of different charging curves at different current densities of charging. Experimental results show that the battery has the best electrical performance when it is charged and discharged at the value of current density between 60 mA/cm2 and 80 mA/cm2.
