Canadian Astronautics Limited (CAL) has developed a system to autonomously manage, and thus prolong the life of secondary storage batteries. The system has been aimed at the space vehicle application using nickel-cadmium batteries but it is expected to be suitable for any recharge able electrochemical couple. The system handles the cells of a battery individually and thus avoids the problems of over, and under, drive. This individual handling allows cells to be totally bypassed in the event of failure, thus avoiding the losses associated with low capacity, partial short circuit, and open circuits. The system contains a dedicated, redundant, microprocessor, but the capability exists to have this computing capability time shared, or remote, and operating through a data link. As adjuncts to the basic management system CAL has developed high efficiency, poly-phase, power regulators for charge and discharge power conditioning.
