The program covers work performed on the EMBC114C Maintenance Free, Nickel-Cadmium Battery System. The EMBC114C consists of a hermetically sealed nickel-cadmium battery and an associated control logic and charger circuit. The Battery System is compatible with existing aircraft electrical systems and may be operated at altitudes up to 100,000 feet. The system is a two-terminal device connected in parallel with the aircraft 28 vdc power. This system was modified to reduce EMI and minimize bus power interruptions when switching from charge to discharge. Tests were performed to verify these modifications. A study was conducted to determine the best charge rate, whether sealed or vented cells were most suitable, and the advisability of using three terminal systems where possible. The EMBC114C is the modified system in accordance with the stated objectives and was qualification tested.
