A high reliability battery management system

Abstract Over a period of some 5 years Canadian Astronautics Limited (CAL) has developed a system to autonomously manage, and thus prolong the life of secondary The system handles the cells of a battery individually and thus avoids the problems of over, and under, drive that inevitably occur in a battery of cel As developed, the system contains a dedicated, redundant, microprocessor, but the capability exists to have this computing capability time shared, or r A number of the units comprising the system were developed to the level of qualification hardware, including a fully redundant discharge converter.
