Storage Battery Internal Resistance Detecting System
摘要
Abstract
This essay analyzes the composition of storage battery in ternal resistance and its measurement. According to its characteristics, this essay mainly takes a view of AC inserting for storage battery on line measurement, illustrating its working principle. In order to measure the internal resistance of storage battery, this essay tells about phase locking amplification method, with TMS320F2812 as its controlling core, as well as designing storage battery internal resistance detecting system, which is composed by lock-in amplifier, filtering, differential amplifier and AD630 balanced modulation etc. The system is easy to be connected to PC, forming an automatic detection network. And it is able to restrain noise and interference, simplifying designing steps at the same time.关键词
