    The Ultimate Charger!

    Hei,

    For NiMh lading fant jeg bla det nedenfor på nette, det som er de alle skriver er at 1 C er ok for rask lading, men at man ikke må overlade dem. Jeg har kjøpt noen av dem og i all manualen står det 1 C.

    NiMH battery,Charging methods for nimh batteries, nickel metal hydride batteries including slow charge, fast charge and smart charge techniques.


    The Ultimate Charger

    Sometimes the most important issue is the lifetime of the batteries or the total lifetime cost of the system. In this case PowerStream is in a good position to offer the ultimate charger because of our wide experience in microprocessor controlled battery chargers and power supplies. Specs for the ultimate charger are:

    1. Soft start. If the temperature is above 40 degrees C or below zero degrees C start with a C/10 charge. If the discharged battery voltage is less than 1.0 Volts/cell start with a C/10 charge. If the discharged battery voltage is above 1.29 V/cell start with a C/10 charge.

    2. Option: if the discharged battery voltage is above 1.0 Volts/cell, discharge the battery to 1.0 V/cell then proceed to rapid charge.

    3. Rapid charge at 1 C until the temperature reaches 45 degrees C, or the dT/dt indicates full charge.

    4. After terminating the fast charge, slow charge at C/10 for 4 hours to ensure a full charge.

    5. If the voltage climbs to 1.78 V/cell without otherwise terminating, terminate.

    6. If the time on fast charge exceeds 1.5 hours without otherwise terminating, terminate the fast charge.

    7. If the battery never reaches a condition where the fast charge starts time out the slow charge after 15 hours.

    8. Fuel gauge, communication to the device being powered, LED indicators all possible.
