Test procedures.

System efficiency. Total input energy to the system and total energy input to the batteries will be measured while batteries are charging. Batteries will be verified to have reached 100% state of charge. Efficiency will be calculated as the ratio of input power to the batteries to input power to the system during charge. A set of (2) BB-2590 batteries and a set of (8) BB-2590 batteries will be charged from both AC and DC power for this test.

Indicator visibility. While operating under Standard Test Conditions (STC) of an irradiance of 1,000 W/m², a solar spectrum of AM 1.5 (per ASTM G173), and a module temperature of 25°C, verify that displays are readable from not less than 3 feet away from the charger.

Direct Query (DQ) protocol. Verify through analysis that the charger is compatible with the BQ2050 standard communication and timing requirement. Verify through testing, using simulated data (for safety), that the charger is capable of charging batteries using the DQ communications interface. Test verification is required for AN/PRC-148 and AN/PRC-152 batteries.
