一种新的基于模型的蓄电池检测技术

为保障蓄电池组的供电安全,对蓄电池进行检测、监测管理至关重要。容量是用户最为关心的问题,准确地检测到蓄电池的满充容量,分析其老化程度,有利于用户及时更换电池,保障备用电源的供电安全。基于电池模型的容量检测技术是根据多频点激励信号得到蓄电池内阻等模型参数,建立容量跟电池模型参数的Kalman滤波结构,反推电池实际满充容量。

A new model-based technology to detect battery

Testing, monitoring and management are essential for a battery in order to ensure the security of the battery power supply. Capacity is a matter of the utmost concern for users. Accurate detecting the full charge capacity of a battery and analyzing its aging level are benefi cial to users to replace batteries timely and to ensure the safety of power supply from the standby power source. Capacity detection technology is based on the battery model and the multifrequency excitation signal obtained battery internal resistance parameters of the model, then established the function of Kalman filter between capacity and cell model parameters. The actual maximum capacity of the battery is calculated with those parameters.
