Abstract

The US Army has developed a nickel-metal hydride (NMH) BB-390 battery system and a two hour charger for Sincgar radios. It can provide 240 watts (10 amperes at 24 volts) of power in the radio´s transmit operational mode. The BB-390 battery replaced the BB-590 nickel cadmium battery. The BB-390 battery contains 40 “A” size cells and provides up to two times the capacity over the nickel cadmium battery with same weight. During charging of the BB-390 NMH battery, the battery will heat up to as high as 57 degrees C. This NMH battery contains 10 thermal devices for protection during both charge and discharge. It is also protected from external short as well as overdischarge. This evaluation is to verify the NMH battery can exceed the military specification requirement as well as to characterize the boundary conditions for NMH battery
