摘　　要：研究并分析了120QNFT6-3方形密封MH/Ni电池在常温下不同倍率的充放电性能,并给出了充放电电压特性曲线;提出了单一恒流充电法、恒流-恒压两阶段充电法和分段恒流充电法,通过比较验证,实验结果表明:MH/Ni电池在常温下具有良好的大电流充放电能力,利用三段恒流充电法可提高充电效率。The charge-discharge performance of 120QNFT6-3 square seal MH/Ni batteries were studied and analyzed at different current rates under the room temperature. And the charge-discharge voltage curves were given too. The charge methods of single constant current, constant current-constant voltage in two stages and constant current in multi stages were proposed. Through comparison and validation, the test results show： MH/Ni battery has favorable high current charge-discharge ability under the room temperature and the charge efficiency can be improved based on the charge method of constant current in three stages.
