| Summary: | 碩士 === 國立勤益科技大學 === 電子工程系 === 104 === Currently, Ni-Cd/NiMH battery is a very popular cell applied in emergency lights or other portable devices. It is known that the battery quality will affect its working life. However, the information about battery quality may not be assured or unveiled from the manufactory. To resolve this problem, this paper aims to design “NiCd and Ni-Mh batteries quality measurement system combined with database management”. Therefore, it can achieve 1. Automatic charging/discharging process, internal resistance measurement and long-term cycle test. 2. Computer-human interface with data acquiring/transmission. 3. On-line test outcome monitoring. The experimental results have confirmed that the proposed system can provide more efficient and convenient information for battery quality.
