摘要：
This paper introduces the principle of valve regulated lead acid (VRLA) battery internal resistance on-line measurement based on digital phase sensitive detection. According to this principle, hardware design such as exciting signal generating unit, single battery selection network and signal adjustment circuit was analyzed in detail. The comparing experiment results show that the system has strong anti-interference ability, high reliability, high accuracy and good repetitiveness.
