(6) cord on/off (7) POWER UP (1) Notes: 1) The system goes to idle when it is power-up. The system is waked up when cord is plugged, motor is turned on or both. 2) Motor is turned on/off by tact switch or slide switch. 3) Motor will be turned off automatically when: a) the voltage of the battery pack is lower than 1.8V or (adjustable externally); b) the motor is drawing current more than the preset limit or (adjustable externally); c) the battery pack temperature is higher than 55C (adjustable externally) 4) During charging when motor is turned on, the charging current is regulated at 1/10 of the fast-charging current. When motor is turned off, the system will determine to go back to pre-charge/fast-charge/full-charge according to the battery usage condition (more details could be obtained in the operation description). 5) Enter fast-charging when a) battery temperature is less than 45C b) battery voltage is higher than 2V or after pre-charging for 3 minutes 6) Enter full-charge state when one of the following full-charge criteria is reached: a) safety timer timeout (4 external selections) b) max. voltage 3.4V (adjustable externally) c) -∆V d) dT/dt (adjustable by component selections) 7) If the battery pack is previously fully-charged without any usage or self-discharged enough, the charger goes directly to maintenance (trickle charge) when cord is plugged again. 8) Charger stops charging current when battery temperature is higher than 55C but resume for charging when battery temperature falls below 45C fast chg (5) 45C > 55C > 55C (8) (8) (8) motor on/off (2)(3)(4) motor on/off (2)(3) motor on/off (2)(3)(4) motor on/off (2)(3) 45C cord off cord off |
