Nickel/Cadmium Aircraft Batteries: Thermal Considerations,
Abstract
Thermal problems in nickel/cadmium aircraft batteries are serious due to effects on battery life and safety of operation. In this study theoretical background of battery heating and cooling was reviewed and confirmatory experiments were carried out. It was found that when nickel/cadmium batteries are charged at low rates cooling takes place but the reverse is true at high rates. Rapid heating takes place during high rate discharges and also during overcharge if the separator materials permit oxygen to reach the negative plate. Magnitudes involved are illustrated by typical examples.
