电池交流内阻自动分选系统

研究了电池交流内阻的自动分选系统。该系统按照ＩＥＣ标准测量电池的交流内阻，使用数字式信号发生器产生测量用的激励信号，稳定性好；消除了接触电阻带来的误差；且具有精度高和抗干扰能力强、实时性好等优点。

Automatic Classifying System of Alternating Internal Resistance of Batteries

The title system is given, in which alternating internal resistance of batteries is measured according to the IEC s tandard.Excitation signal generated by a digital signal generator isstable, the tester with four-terminals eliminates the measuring errors caused by the contact resistance, and high precision and strong anti-disturbance is due to integral A/D converter, andsoftware system using multitasking techniques has the advantage of real-time ca pability.
