摘要
针对蓄电池内阻测量方法的不足,利用锁相放大技术设计了一种改进的电池内阻在线测量电路,并在Lab-VIEW软件中对其进行了仿真分析。结果表明,该内阻测量电路能有效地抑制噪声干扰,减少相移误差,可实现对蓄电池微内阻的精确测量。
Aiming at the disadvantages of testing methods for lead- acid battery internal resistance, an improved on-line testing circuit is designed with the lock- in amplifying technology, and the simulation is analyzed in LabVIEW. It＇s shown that this proposed testing circuit can suppress noise disturbance effectively and reduce phase- shifting error to test battery internal resistance with high accuracy.
