Ultra High Energy Rechargeable Battery (Army)
Abstract
The BB-2590/U battery is rechargeable. It consists of nickel/lithium-ion cells and is used in many US Army portable radios & electronics equipment. It is the most widely used battery in the Army inventory. The new BB-2590/U weighs 2.8 pounds with dimensions of 4.4 x 2.45 x 5.00 inches. The nominal voltage and capacity is 28.8 Volts and 7.9 Amp-hours (Ah), respectively. Compared to the current production battery, the new BB-2590/U battery will have one hour (30 percent) greater service time, 1.6 Ah (24 percent) greater capacity, and 38 Watt-hours (20 percent) greater energy. At -32 °C and five amperes (Non-Line-Of-Sights requirement), the new battery will provide 1.3 hours service time and 165 Watt-hours energy; whereas, the current production battery will not operate at all at -32 °C . The battery weight will be reduced by 71 grams per battery. Not only will the new battery weigh less than the current battery, the soldier will have to carry fewer quantities of batteries for a specific mission. This is because the new battery will provide greater run time; therefore, fewer quantity of batteries required.
