Nickel -hydride battery charger charging program logic

　　Fast charging: 1cma (fast charging temperature range: 0 ℃ -40 ℃) is to properly control the fast charging, and the charging current should be between 0.5 --1.0C. The charging current is greater than 1C, which may increase the internal voltage of the battery but the safety valve starts, causing the battery to leak. When the battery is charged than 0 degrees or more than 45 degrees, the trickling should be charged.

　　2. Using a large current to discharge or deeply discharge batteries, it is impossible to fully restore the capacity of the battery

　　When charging a battery that discharge or deep discharge, first charging with a trickle. After the voltage rises, the fast charging current is charged.

　　3. Quick charging start voltage: about 0.8 volts/one

　　4. The upper limit of the charging voltage control L: about 1.8 volts/one

　　When the battery voltage is close to 1.8 volts/size in some aspects, the charging should be converted to a trickle charging.

　　5.-AV value: 5TO 10mv/only.

　　In fast charging, when the voltage decreases from 5-10mV, the fast charging should be stopped or converted to a trickle charging.

　　6.DT/DT value: about 1TO2 degrees/minute

　　In fast charging, when the temperature rise of the battery during the unit time of the thermocouple or other temperature measuring components, the fast charging should be stopped or turned to the trickle charging.

　　7.TCO: 55 ℃

　　During the charging process, if the battery is overheated, it will damage the cycle life and other characteristics of the battery. To prevent such situations, when the battery temperature reaches the preset value, quickly charging stops and turns to the trickle charging

　　8. Initial delay time: 10 minutes.

　　This can not start at the specified time after the fast charging start. However, the DT/DT monitoring circuit can work normally during this time.

　　9. Po-charging current: 0.033 --- 0.05cma.

　　When the cave charging current is too high, the battery temperature will increase, which will worsen the performance of the battery.

　　10. Quick charging timer: 72 minutes (1C charging)
