摘要
根据铅酸蓄电池组的充放电特性,采用工作电流放电法测量蓄电池组的蓄电能力。设计了铅酸蓄电池组蓄电容量的计算机在线监测系统。该系统在测量过程中可以对电池放电时的剩余电量给出线性的指示。蓄电池组放电时对电池组单节电压进行巡检,发现性能开始下降的电池,排除电池失效的隐患。在浮充状态下在线测量电池的内阻,在非放电的条件下发现电池性能的变化。通过计算机对铅酸蓄电池组的各参数的在线监测,实现了铅酸蓄电池组监测和预警的自动化。
The computer on-line monitoring system of value regulated lead acid batteries（VRLA） capability is designed using the method based on operating current discharge in accordance with charge/discharge characteristics of VRLA.The system could show the linear instructions of residual capacity of VRLA while discharging in the measurement process.Also the system can detect the single voltage of VRLA,and find out the batteries with degenerate performance to rule out the hidden trouble of failed VRLA batteries.The system can measure internal resistance of battery on floating condition,and find changes of performance of VRLA on condition of non-discharge.The automation of monitoring and early warning of VRLA is achieved,through online monitoring various parameters of VRLA using computers.
