| Abstract: | 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. |
